7 Disorders Related to Social Anxiety Disorder

7 Disorders Related to Social Anxiety Disorder February 18, 2020 Social Anxiety Disorder Overview Symptoms & Diagnosis Causes Treatment Living With In Children Slavica/E/Getty Images In This Article Table of Contents Expand Avoidant Personality Disorder Panic Disorder Generalized Anxiety Disorder Depression Alcoholism Eating Disorders Schizophrenia Comorbidity in social anxiety disorder (SAD) refers to having another disorder in addition to SAD. Having SAD increases the chance that you will be diagnosed with another disorder, and also makes receiving treatment more complex.?? Many disorders are related to social anxiety disorder (SAD), including other anxiety disorders, depression, and personality disorders. Avoidant Personality Disorder If you have avoidant personality disorder (APD), you will experience many of the same symptoms as someone with SAD. However, your symptoms will be broader and more severe.?? Because of the overlap between the two disorders, it is possible to be diagnosed with both APD and social anxiety disorder. One of the key defining features of avoidant personality disorder that tends not to be present to the same degree in SAD is a lack of trust in the motives of others. While those with APD feel others are not to be trusted, those with SAD tend more toward feeling as though others are judging them. Panic Disorder Panic disorder differs from SAD in terms of the triggers of panic, the kind of symptoms that are experienced, and beliefs about the underlying causes. It is possible to be diagnosed with both panic disorder and social anxiety disorder, and the treatments may or may not be the same for both disorders. While individuals with panic disorder and social anxiety disorder may share similar patterns of avoidance and experience some of the same types of symptoms, a key defining difference is that persons with panic disorder often feel better in the presence of a trusted companion, while this may cause those with SAD to feel more anxiety.?? Generalized Anxiety Disorder If you suffer from generalized anxiety disorder (GAD), your worry tends to be broad and general, rather than focused on social or performance situations. You might worry about finances, your job, global warming, family issues, or any number of things. Your worry probably keeps you awake at night and may morph into physical symptoms such as tension headaches or migraines. People with social anxiety disorder, on the other hand, usually are limited to feeling anxiety about social and performance situations. Depression There is an established relationship between depression and social anxiety disorderâ€"if youve been diagnosed with SAD, you are more likely to develop depression later in life.?? Whats more,  people who suffer from both depression and social anxiety disorder  often only seek help for depression, even though they may have had severe social anxiety for many more years. Unfortunately, treating depression without also treating underlying social anxiety will not be as effective. This is why it is important to share all of your symptoms with your doctor, and for physicians to be alert to potential signs of social anxiety disorder. Alcoholism If you suffer from social anxiety disorder, you are more likely to also suffer from alcoholism.?? Often people with SAD begin drinking to copeâ€"but eventually drinking becomes a problem in its own right. If you have both social anxiety disorder and alcoholism, treatment must be tailored to your unique situation to address both issues. Eating Disorders Social anxiety disorder and eating disorders, such as anorexia nervosa, bulimia nervosa, and binge eating disorder may sometimes be diagnosed together.?? Fear of eating in public is a common symptom, but the types of behavior and motivation underlying it are quite different. People with anorexia may fear being judged for overeating and may shift food around on their plate, while someone with SAD may fear spilling a drink or have shaking hands while eating. Schizophrenia While comorbid SAD and schizophrenia has received less attention, there is some evidence of increased risk for social anxiety disorder among those with schizophrenia.?? For those with schizophrenia as well as SAD, quality of life can be lowered.   A Word From Verywell If youve been diagnosed with social anxiety disorder along with another comorbid disorder, your doctor will determine the best course of treatment to manage the complex interaction between your symptoms. In order to receive the best possible treatment, be sure to share all of your symptoms during diagnosis, so that a complete picture of your circumstances emerges.

Over the years, there have been many definitions of insurance but the most accepted definition is that given by ALAN WILLET in 1901. He defined insurance â€Å"As the accumulation of reserves for the purpose of contingencies†. Thus it is a business activity wherein some people or parties who are subject to certain risk pay monthly or yearly premium to an insurance company to transfer the burden of such risks. We will write a custom essay sample on An invesigation of the contribrution or any similar topic only for you Order Now Insurance also may be defined â€Å"as a contract whereby a person called the insurer or the assure agrees in consideration of money paid to him called the premium by another person called the insured or assured to indemnify the latter against losses resulting to him on the happening of certain events†¦. J. O. Rusk (1991)†. The origin of insurance initially had a connection with ships and cargoes achieving a spread of risk. This origin dates back to as early as BBC (carter, 1991) when the â€Å"Babylonians developed a system of loans on maritime ventures whereby the loans were not repayable in the event of the loss of the venture†, to the emergence of modern insurance development which owes its credence to Great Britain, though insurance Ewing introduced into Britain by the Lombard in the 14th and 1 5th centuries (Cooker, 2002). Insurance is an intangible service paid for and received at a future date. The technicality of insurance makes it obvious for uneven incidence of risks when there are infinite numbers of identical risks. It is also a risk transfer mechanism which provides enormous benefits to the individual/organizations (both profit and non- profit), government and socio-economy at large. Every individual or organization is faced with the likelihood of a loss, injury, destruction of life or properties; hence, it is asserted that â€Å"Risk is concomitant of life† (Chipolata 2006). In other words, risk is unavoidable. Since It is a form of risk management primarily used to hedge against the risk of a contingent, uncertain loss, it is therefore because of the liability of an organization to predict the future that insurance is purchased. 1. 2 DEFINITION OF RISK The term risk is a simple notion which cut across a layman’s definition to the technicalities of business practices. When someone states that there is risk in a particular situation or context, be it business or an event, the ordinary listener understands what it means on the face of it. What then is Risk? This question can easily be answered by adopting a generally accepted definition of Risk by a renowned scholar, Dry Matthias G. Healer. He defines it as the possibility that positive expectation of a goal-oriented system will not be achieved (uncertainty) and this will be due to either certain human or inhuman factors. Furthermore, risk refers to the uncertainty that surrounds future events and its outcomes. It has an expression which looks again at likelihood and impact of an event with the potential to influence the achievement of organizations objectives. When â€Å"risk† is said to exist, there is also the likelihood that expected results may not match those results hoped for I. E. A deviation. Benjamin Franklin in his book observed that in this world nothing can be said to be certain, except death and taxes. Yet there is some uncertainty about those two phenomena: no one can be sure when he/she will die, and tax rules and rates are frequently changed. In fact, the whole of life is surrounded by uncertainty. In some situation uncertainties are within the control of individuals or firm, others are part of the environment in which our lives operate. However, the word ‘risk used here changes. Insurance is an unsought good and the uncertainty in future events is what is being insured. Insurers’ profitability in any portfolio depends largely on the frequency, the severity of its impact and its final results (uncertainty). Uncertainty is not merely a dimension of threats, hazards and risks but opportunities which if anticipated may result in a reward. The risk is the thing which is insured, the insured peril, the expected claims cost for any given policy, or as a general term for unwanted and uncertain future events. 1. 3 RISK MANAGEMENT AND INSURANCE Organizations had long practiced various parts of what has come to be called risk management. Risk management is attempting to identify and manage the threats that could severely impact or bring down an organization. The management of risk is a fundamental aspect of entrepreneurial activity. Entrepreneurs manage the risk of accidental loss by weighing the costs and benefits of each alternative. In a structured risk management process, this involves: 1. Identify and analyze the loss exposure. 2. Formulate alternatives to dealing with such exposure 3. Select the apparent best techniques to treat exposure . Implement the decisions made 5. Monitor the effectiveness of the decisions implemented. Those who do not apply a structured process still make decisions about risk, although sometimes by default rather than design. For industrial or commercial firm, the objective of risk management may be to maximize profits, or to increase revenue, net worth or perhaps market share over some period, or to achieve a combination of several objectives, or Just to stay in business. Managing a multitude of internal and external risks is one of the most significant challenges facing organization set up today. Insurance serves a number of valuable functions that are largely distinct from other types of financial intermediaries. In order to highlight specifically the unique attributes of insurance, it is worth focusing on those services that are not provided by other financial services providers, excluding for instance the contractual savings features of whole or universal life products. The indemnification and risk pooling properties of insurance facilitate commercial transactions and the provision of credit by mitigating losses as well as the measurement and management of non diversifier risk more generally. Typically insurance contracts involve small periodic payments in return for protection against uncertain, but potentially severe losses. Among other things, this income smoothing effect helps to avoid excessive and costly bankruptcies and facilitates lending to businesses. The scope of an economy’s insurance market affects both the range of available alternatives and the quality of information to support decisions. For example, a manufacturer might produce only for the local market, forgoing more lucrative opportunities in distant markets in order to avoid the risk of losing goods in shipment. Transport insurance can mitigate this loss exposure and enable the manufacturer to expand. Similarly, to avoid the risk of total loss from drought, a commercial farmer may keep half of his seed in reserve. 1. 4 INSURANCE CONTRIBUTION TO AN ORGANIZATION Insurance through effective risk management contribute specialized expertise in the identification and measurement of risk. This expertise enables them to accept carefully specified risks at lower prices than non-specialists. They also have an incentive to collect and analyze information about loss exposures, since the more precisely they measure the cost of risk, the more they can expand. Over the years, the realization of risk management with the help of insurance has contributed enormously in achieving organizational goals severally. For instance, 0 It guarantees as far as possible, that the organization will not be prevented from pursuing its other goals as a result of losses associated with pure risks. 0 It contributes to profit by controlling the cost of risk for the organization 0 It can also reduce expenses through risk control measures (insurance) and as such increasing income. As a result, the insurance market generates price signals not only to manufacturing sector but to the entire economy, helping to allocate resources to more productive uses. Insurers also have an incentive to control losses, which is a significant social benefit. Most fundamentally, the availability of insurance enables risk averse individuals, entrepreneurs and organizations to undertake higher risk, higher return activities than they would do in the absence of insurance, promoting higher productivity and growth. . 5 PROBLEM ANALYSIS All manufacturing companies are set up with a primary objective to produce goods that meet the needs of their customers and also to maximize profit. In the process of manufacturing goods the company is often exposed to varying and diverse risk(s) which affects all the factors of production. In as much as these factors are exposed, the logical conclusion is that the income of the company is threatened. Human lives are exposed to industrial injuries which sometimes end up in death, permanent or temporary disability, properties could be destroyed through fire out break or explosions, and liabilities could be incurred arising from the consumption of the product. When less emphasis is placed on these loss exposures, it will definitely lead to the demise of the company. This project therefore, will look at the effect of insurance in manufacturing sector and also whether manufacturing companies who place major significant on insurance are successful in their total business effort all other things being equal. . 5 PURPOSE OF STUDY As earlier mentioned, the aim of any manufacturing company is to maximize profit and ensure customer satisfaction. It is quiet obvious that in carrying out production the organization is exposed to so many risks. This study is focused on the effect of insurance in manufacturing these products, in essence, how risks that could not be voided, minimized, reduced or retained can be transferred to insurance companies while the organization focuses its attention to its real business. Our study seeks: 1. To find out how risks/ loss exposures has been managed in Banana breweries 2. To examine the effect of insurance in the development of the organization (Banana Breweries) as a case study 3. To examine risks that they have managed by way of transfer to insurance and how adequate are the various insurance covers. 4. To consider the extent to which insurance has contributed to the attainment of the corporate goals of Banana Breweries 5. To make policy recommendations on how insurance will assist to further develop Banana Breweries, GAMBLE, and The Gambia. 1. 6 RELEVANT RESEARCH QUESTIONS The research exercise is set out to answer the following questions: 1 . What is the level of insurance awareness in the manufacturing sector of The Gambia 2. Does insurance enhance corporate development 3. Has your company ever sustained any unusual, large or unique losses either insured or uninsured 4. Is insurance an effective risk transfer mechanism. Due to time and other constraints, the researchers had to narrow the scope of their duty to Banana Breweries co. Ltd and Gamble in The Gambia. The study shall focus on the effect of insurance in the above listed companies as well as its benefits. It will assist the company to continue appreciating the role that insurance plays in their activities, and also serve as a means of reviewing improvement measures in place which hopefully will bring about uncovered areas of loss exposures to their operations. 1. 9 SIGNIFICANCE OF STUDY All manufacturing companies exist to ensure that the shareholders maximize their wealth. Companies therefore undertake economic activities for profit. However, in heir pursuit of this venture all the factors of production are exposed to one risk or the other. Those study is primarily laying emphasis on the essence of insurance which will significantly aid the manufacturing concern to achieve their broad objectives, through a well coordinated and scientific measurement and assessment of the various risks that the manufacturing company is exposed to. The study will assist the company to continue appreciating the role that insurance plays in their activities, serve as a review of existing measures in place and hope to bring out uncovered areas of risks to their operation.

In other words, there may be no cause at all for being fired. Nonetheless, there are some instances when an employee may be summarily dismissed from work for a very good reason. There is no written work contract between an employer and employee when it comes to the terms and conditions of the employment-at-will (Sentell Robbins, 2008). In sp ite of the missing written contract, it does not imply that employers have the right to fire their workers at any time they wish and of course without any good reason. It is vital to mention that the terms of service for employees should be guaranteed so that they can feel safe and secure throughout their working period. When it comes to the law, there is a general assumption that workers are employed at will except when they are in a position to prove otherwise. This implies that it is the duty of employers to provide either verbal or written statements for employees before they assume duty in order to minimise any possibilities of erroneous dismissal from work. However, it can be cumbersome to substantiate oral statements from an employer especially when there are no records in place (Sentell Robbins, 2008). The respect of workers is violated when they are employed at will. It is indeed true that employees should be contended with any outcome of their terms of service having acce pted the prevailing conditions voluntarily. Nonetheless, it still calls for caution, respect and dignity before an employer makes the final decision to dismiss an employee from workplace. For example, whey would a worker be fired without any reason? After employees have been hired, they are usually expected to be top performers and productive workers throughout their tenure. As a matter of fact, employers expect a lot from employees once they have been hired. It does not matter whether there are written contracts in place. The main point of concern is productivity at workplace. On the other hand, an employee should be rewarded as part of motivation.Advertising Looking for essay on business economics?

As already hinted out, job security is a crucial source of motivation for employees. Eve n for a short period an employee is hired, he or she should feel a sense of security. This goes along with respect and dignity (Sentell Robbins, 2008). The latter also account for motivation that employees require at workplace. On a final note, most job seekers are often desperate to secure employment opportunities whenever any chances show up. They hardly care about reading the terms and conditions of the available working opportunities. In the event that they clearly understand the terms, the urgent desire to land on any job is usually the first priority. Consequently, they are employed-at-will and eventually subjected to the involuntary firing from workplace. Needless to say, employers who dismiss employees without any apparent good reason grossly violate the basic rights of such workers. Reference Sentell, E., Robbins, R. (2008). Employment at-will.

Free Essays on Gangs

"Once inside, I was walked through a gauntlet of desperate men. Their hot smell in the muggy corridor was as foul as their appearance. None of them seemed to have a full set of front teeth. Many bore prominently displayed tattoos of skulls or demons. One could argue whether it was the look of these men that led them to prison or whether it was the prison that gave them their look. Just looking at them made me fear for my life" (Hassine, 7). Most inmates in correctional facilities felt the way that Victor Hassine felt on his first day in a correctional facility in Pennsylvania called Graterford State Prison. New inmates are seen as "fresh meat". They fear their life. Most of these inmates find sanctuary in gangs. Inmates join gangs for protection. Gangs in correctional facilities are more of a necessity, unlike street gangs. People don't need a gang to survive in the street because there are other ways one can find help, a family, protection, belongingness, etc. But in correctional facilities one's outlets are limited. One's preoccupation in jail is survival, which leads inmates to change their habits, personality, and even their values. Living in an environment where "an unexpected smile could mean trouble, a man in uniform is not a friend, being kind is a weakness, and eye contact is a threat" doesn't leave one much of a choice, does it? There are numerous gangs in correctional facilities but among the most common are the Latin Kings, Five Percent Nation, and the Netas. Some gangs in these facilities are extensions of neighborhood street gangs. Their names are based on their urban location, like the 21st and Norris Gang, the 60th and Market Gang, and the 10th Street Gang in Philadelphia. There are also less common prison gangs like Los Solidos, Latin Locos, G27, Nation, Brotherhood, Elm City Boys, 20 Luv, and Esses. White gangs almost always originate in prison and are a minority. They a... Free Essays on Gangs Free Essays on Gangs The book that I chose to read was a book called â€Å"Gangs† by a woman named Karen L. Kinnear. I chose this book for one simple reason, the tag at the bottom of the front cover. The tag on the cover says Contemporary World Issues. I wanted to read something that was current in today’s society and it was something that is pretty familiar to many young black men these days. If black men are not involved in gangs then they are very knowledgeable about them. This book talked about what gangs are, who joins gangs and why, and many other facets involving gangs. According to the book, a gang is very difficult to define. This is so because of the questions proposed. One question that was asked was if a gang is just a group of people who hang around each other. Then another question that was asked was if adults in a group could be classified as a gang. Then it was asked if the group has to be involved in some kind of criminal behavior. All these questions make it obvious to see that gangs plague today’s society to a point that we can not even put a definition on what a gang really is. According to this book by Karen Kinnear, defining gangs is often a political issue that reflects the interests and agendas of the various individuals and agencies involved with gangs. These individuals and agencies would happen to be law-enforcement personnel, politicians, advocates, social workers, the media, and researchers. After reading this part, I was highly shocked at how true that really was, and I really never recognized that until readin g it here in this book. The definition of a gang has changed from each person who defines it to the next. A researcher named Frederic Thrasher decided to offer his definition in the year of 1927. He said that a gang â€Å"is an interstitial group, originally formed spontaneously, and then integrated through conflict. It is characterized by the following types of behavior; meeting face to face, milling,... Free Essays on Gangs Gangs are a violent reality that people have to deal with in today's cities. What has made these groups come about? Why do kids feel that being in a gang is both an acceptable and prestigious way to live? The long-range answer to these questions can only be speculated upon, but in the short term the answers are much easier to find. On the surface, gangs are a direct result of human beings' personal wants and peer pressure. To determine how to effectively end gang violence we must find the way that these morals are given to the individual. Unfortunately, these can only be hypothesized. However, by looking at the way humans are influenced in society, there is good evidence to point the blame at several institutions. These include the forces of the media, the government, theatre, drugs and our economic system. On the surface, gangs are caused by peer pressure and greed. Many teens in gangs will pressure peers into becoming part of a gang by making it all sound glamorous. Money is also a crucial factor. A kid (a 6-10 year old, who is not yet a member) is shown that s/he could make $200 to $400 for small part time gang jobs. Although these are important factors they are not strong enough to make kids do things that are strongly against their morals. One of the ways that children’s morals are bent so that gang violence becomes more acceptable is the influence of television and movies. The average child spends more time at a TV than she/he spends in a classroom. Since no one can completely turn off their minds, these children must be learning something while watching the television. Few hours of television watched by children are educational, so other ideas are being absorbed during this period of time. Many shows on television today are extremely violent and are often shown from a gang's perspective. A normal adult can see that this is showing how foully gangs are living.

Free Essays on Gangs Gangs have been and will always be a part of society, They have in one form or another been around for hundreds of years. For example pirates were in some way or another a form of an organized gang. The groups that traditionally come to mind when one thinks of modern day gangs are the Crips and the Bloods from California, and the people Folk originating from Chicargo. The origins of the Crips and Bloods can be traced to the late 60's, and the gang culture is so ingrained on the west coast that many families have three and even four generations of gangsters residing in the same residence. The people Folks started out in the late 70 and early 80’s Depending on whose figures you listen to (some officials have a tendency to downsize the numbers). As of January, 1993, L.A. gangs set’s numbered between 800 and 1000, with anywhere from 120,000 to 220,000 members. These numbers are often debated, and depending on whose criteria is used to decide who is and is not a gangbang er. The figures could be considerably higher. This paper will elaborate on some of the facts surrounding Juvenile gangs. Over the past several years we have seen a increase in the number of juvenile crimes and juveniles joining organized gangs. These juveniles are not only joining at a younger age but are committing more violent crimes then there antecedent. What makes these young men and women decide to participate in the violent and often deadly crimes of gangs? Why would a youngster be so eager to submit himself or herself to the torture of initiation or risk there life by having sex with a known person that’s HIV positive? Although varies regions of the country may have different meanings or definition for the term "gang member" a good description for a gang can be found in the November 1991 issue of school safety update published by Pepperdine University’s National School Safety Center, it defines a gang as "A group of three or more individuals with...

Free Essays on Gangs GANGS AND THEIR EFFECTS ON FAMILIES Introduction The aim or objective of this paper is to thoroughly report on why individuals join gangs and how gang membership can put people’s friends, family and even themselves in jeopardy of being seriously injured or killed. The researcher is aiming towards a few topics on this paper such as gang membership, graffiti, violence and vandalism, and spreading gangs. Most people do not realize or do not know how dangerous gangs can be and this can lead to serious consequences. Literature Review Gangs affect the enviroment or city in which people live. They affect the enviroment of families and cause harm to victims and witnesses in areas of gang territory. Incentives or becoming a gang member, graffiti in the neighborhood, gang violence, the spread of gangs, and gang prevention will be explored thoroughly. The research found on gangs mainly focused on adolescent and young adult males. The most popular reason for joining a gang is coming from a dysfunctional family and wanting a sense of having a family (Lahey). These types of people do not think very highly of themselves. They feel good belonging to a gang because they believe that their family, friends or community has not paid any attention to them. People of certain races or cultures may believe that they are powerless or have no opportunities. Gus Gedatus states that â€Å"they may not feel that they are apart of society† (Gedatus 8). These types of people look at participating in a gang as being cool. Another popular reason for joining a gang is to follow family tradition. Some people’s parents or maybe even grandparents have belonged to a certain gang and will be upset or feel that the person is betraying the family. Youth form gangs because people fear it. This fear may give the members a sense of power. These types of gangs tend to move into neighborhoods that are unfamiliar with gang activit y in ... Free Essays on Gangs â€Å"GANGS† Across the United States there is a type of subculture that needs to be dealt with and destroyed. Gangs are the type of subculture at hand. Gangs can be defined as a subculture because they exist within society while maintaining their own norms, beliefs, and values. Gangs are a subculture of violence, whose values demand the use of violence in overt situations (Adler, Mueller, Laufer 2001). Gang membership promotes violence and other delinquent behavior from its members (such as vandalism and drug relations). Gangs need to be abolished if we hope to clean up our streets, get our children back in school, and have a chance at winning the drug war. Are you as person looking to seek a public office ready to deal with this issue? I will continue to give you some background knowledge of gangs. Let the fact be known that it is not illegal to be in a gang, but once a criminal action takes place gang members have stepped over the line and their membership is now perceived as illegal. One of the main ways that gang membership forms is from generation to generation. A child is exposed to the gang activity taking place in his or her neighborhood and may want to take part in this gang to fill an emotional void. This void might be in need of love from a â€Å"family† group, respect, or a sense of belonging to a peer group. A child might have older siblings that are members of a gang and the younger child longs to be like the older sibling. Youth might also join a gang for the protection from other gang violence and the chance to make money fast. Whatever the reason is for joining gangs, America’s youth believe that gang membership allows them to achieve a level of status that was impossible to attain outside of the gangs. It is estimated that there are more than 24,500 gangs active the United States in 2000 (Egley, 2001). The average number of gang members for 2000 was 750,000 (Egley, 2001). These number...

Technical Definitions - Coursework Example The attack is considered to be a deliberate action whereby the terrorists release the viruses, bacteria and the germs in order to come with an effect into the environment which will affect any living creature around. The germs, bacteria and viruses are said to be natural and they can be accelerated by use of the biological chemicals and tactics in order to be used negatively into the society. The effects spread into the whole society affecting the living creatures. One of the major reasons for the use of the biological agents is because they have the ability to spread through air, water and food ("Bioterrorism: Learn the Definition and Agents Used." 14). All the three modes of the agent’s flow can affect the environment very greatly. One of the major question over Bioterrorism is, How can it be stopped or be regulated? In the prevention of the attacks there are certain ways that can be used in order to prevent the attack. As a resident of Texas, one must report any suspicious attack that can be realised by reporting the matter to the Department of state of the health services. This is because the staff in the Department depend on the interactive and information of the citizens. Another second way on how to prevent such actions is to elect officials in the offices of the health services in Texas who will be concerned with the health and well being of the living creatures in the city of Texas. However those may not be the only prevention methods for the attacks but with the two key points, the state of Texas can be well prevented from the biological effects and enable a solid prevention over the threats by the bioterrorists.

Health care professional inerview - Essay Example These tasks are done both in the hospital setup, at the home of patients, within the community schools as well as in industries. Community paramedics thus deliver services to emergencies with the main objectives of prevention of health harm. Paramedics offer their services round the clock to address the health concern of people in the community. This work mainly targets those whose capacity is impaired and the vulnerable members with the intention of achieving a universal coverage of health. Vickie L. Martin elaborated that a typical day for a community paramedics is one parameter that is difficult to predict. She states that a paramedic officer is an individual trained to be prepared all the time for an emergency whether on duty or off duty. A typical day for a paramedic officer can begin by responding to an emergency entailing fire outbreak or flood. Paramedics are responsible for the resuscitation of the victims of the crisis, offering first aid services and transferring those in need of special health services to a health care facility. The duty of a paramedic can take unpredictable duration in an emergency sport. Nevertheless, community paramedics are trained to offer their services within the shortest time possible as a way of allowing time to respond to other situations. The day is equally spent reporting emergency services to the relevant authority as well as collaborating with other health care workers to deliver services in hospital and community setting. A community paramedic works in a multivariate practice setting, these include in the community, giving services to the community. A professional in this field can equally practice in a health facility as well as in the research institutions. Working in an environment that demand speed in action, community paramedics work with the ambulance services as well as with the emergency airlift services for quick delivery of health care needs. According to Vickie L. Martin, the requirements

The Potential Of Wind Assisted Ship Propulsion Engineering Essay

The Potential Of Wind Assisted Ship Propulsion Engineering Essay Wind is present all around the world, and in some places with abundant energy density. Wind had been extensively used in the past, for mechanical power in addition to transportation (J.F. Manwell and J.G. McGowan, A.L. Rogers (2009)).Wind energy has evolved into one of the most practical, cost-effective and both environmentally and technically attractive, of all the renewable energy options in the world. So the wind energy has a lot of potential at sea for assisting in ships propulsion. Wind is the cheapest, most powerful, and greenest source of energy on the high seas. The accelerating fuel costs over the last decade have led to growing interest in the application of wind assistance for ship propulsion and reduce fossil fuel consumption. Using wind energy for propulsion of ships in sea is in fact one of mankinds oldest ocean-going technologies. In one-way or another, with modern advances in ship design and propulsion the use of wind energy was almost forgotten Sail systems were the dominant form of propulsion until the 19th century (http://en.wikipedia.org/wiki/Marine_propulsion) Astrophysicist Carl again writes, for example, that: the consequences of scientific illiteracy are far more dangerous in our time than in any that has come before. Its perilous and foolhardy for the average citizen to remain ignorant about global warming, say, or ozone depletion, air pollution, toxic and radioactive wastes, acid rain, topsoil erosion, tropical deforestation, exponential growthà ¢Ã¢â€š ¬Ã‚ ¦.How can we affect national policyà ¢Ã¢â€š ¬Ã‚ ¦ if we dont under stand the underlying issues? Aim and Objectives: The main of the project is to analysis into the potential of Wind Assisted Ship Propulsion (WASP) and its application into the modern day shipping. WASP systems will be explained, analysed by showing its benefits and drawbacks. The applications and possible benefits of the use of the WASP will also be investigated showing all the relevant factors that are affected by the use of WASP. The key objectives are summarized as: Research into present and evolution of WASP systems, Potential of present WASP system and their applications. Advantages and future development of WASP systems Discussion of economic and environmental factors Analysis into the use of alternative energy sources at sea. Evaluation of WASP by application to a case study Critical analyse into all findings to produce a logical and well founded conclusion. EXISTING WASP SYSTEMS: The following are the remaining WASP Systems in use at present in the sea Aerofoil(Wing-Sail) Flettner Rotor Rig Soft Sail Towing Kites (Skysails) Wind Turbine (Skysails) Aerofoil (Wing-Sail): This form of marine propulsion works in the similar way as an aeroplane wing, producing pressure differences between opposite sides which create a force , supported by central mast. The trust provided by the solid structures of the sail is more with less drag than conventional sails. This technology came into wide development in 1980s by Japanese and still some vessels use this technology nowadays with research into the application of such systems proceeding. Various research is been carried out and one of the example using this aerofoil concept is this ship model which is called the ecoliner. It is a type of cargo vessel which propels by using combination of high-tech sail and engine power. This combined feature, make it possible to work like a normal cargo ship with similar service of speed, freight price and other factors. Using this ecoliners , as ocean transports will decrease the pollution emissions to 50% of the ship. MV Ashington vessel is a bulk carrier which has auxiliary propulsion with the use aerodynamic wing sail. (http://www.shipspotting.com/gallery/photo.php?lid=823976) A computer controlled wingsail fitted to the 6,500 dwt dry cargo ship mv Ashington resulted in a fuel savings average of 8% and, under favourable circumstances, of up to 20%. (htt p://www.maritimejournal.com/features101/power-and-propulsion/wingsail_ready_for_small_commercial_vessels) The wing-sail have two significant drawbacks which are considered. First one is that the moments coupled with the lift forces which produce the propulsion also can create a large aerodynamic drag force which acts as a huge drawback when sailing directly into a head wind(Clayton, 1987).Rigid sails then usually themselves into the wind direction when no force can be created while some design allow the surface to be folded using hydraulic controls such that the direction can be controlled. In general wing-sails have a high lift coefficient compared to soft sails which will be discussed in further topics. This means this system has more advantage over the other conventional sails even though initial investment in the system will be high. Various designs now incorporate a frame with a material surface to keep the minimum weight. Flettner Rotor Rig: Flettner rotors consist of cylinders which are of spinning type and tall mounted onto the vessels deck. The vessel is set in motion by using the Magnus effect. The Magnus effect is produced whenever pressure difference occurring around spinning object. This concept was done by researcher Anton Flettner, a German naval architect. Later researchers conducted experimenting into its operation in 1980 when Saudi oil crisis happened. But this system never overtook the diesel engine usage. However in the 1920s Fletner rotor operated in sea for a quiet a long year proving reliable form of wind propulsion. To understand this system works, an understanding of the Magnus effect is necessary. The Magnus effect or force happens when there is a pressure difference around a spinning object. Because of this change in boundary later around this object happens, a lift force is generated in direct propulsion to the acceleration it imparts on the air streaming by (Seufert, 1983). This lift force happens due to Bernoullis principle; this use of the principle is highly effective and is described as practicable. Soft Sail: Soft Sail system consists of two main types, the modern square rig and the fore and aft rig. The square rig is the most efficient running rig and useful to longer routes with more constant and foreseeable winds.Fore and aft rig type is suitable to short routes, where the wind speed and direction be unlike. In modern day shipping the soft sails is not used, because of its large propulsion of deck space and needs constant manning. The reason for this is because the other types of sailing systems are more effective and efficient compared to these soft sails. The sky sail lakes large portion of deck space and always need constant manning. With deck space is considered more important for carrying cargos in present shipping world, it makes less effective in use and outweighs the advantages of any soft sail systems. The future of ship propulsion may consider this soft sail with combining with other types of propulsion to take advantages and use it in a efficient way. However there are some smaller vessels like fishing boats still depend on soft sails as an auxiliary propulsion force and the uses of soft sail are important in this fishing boats Towing Kites (Skysails): Towing Kites function on same basis as several conventional kite arrangements used on such things as Paragliding and kite boarding, etc. the propulsion of the vessel is assisted by the kite which harness the energy from wind. Since wind-conditions are not always sufficient, the Skysails system is designed to function as a supplementary power source, in addition to the ships engine. Skysail consists of a towing kite, a control system, a launch and recovery system and a wind-optimized routing system. The Para foil kite is constructed out of  high-strength, weatherproof textiles, and  is designed in such a way that it can achieve optimal aerodynamic efficiency at any wind speed. The steering system operates automatically and is composed of the control pod and the control system. The towing kite and the towing rope are linked by the control pod. Much like autopilot systems in airplanes, the Skysails sensors collect data that is processed by the systems software, which sends control orders accordingly. The launch and recovery system is responsible for automatically recovering and launching  the towing kite, control pod and towing rope. The kite is attached at only one point to the launch and recovery mast, enabling high manoeuvrability. A telescopic mast lifts the towing kite  during its launch. The wind unfolds the kite to its full size while the reef system launches the reef ropes. While the towing kite is decoupled from the launch and recovery mast, the towing rope is released. The power transmission system consists of a  towing rope, a force transmission point (tow point), and winch, and is responsible for transferring the tractive force from the kite to the ship.  The mounting system ensures that the towing kites force is aligned ideally to suit the winds direction. The routing system is composed of  a weather forecasting performance calculator, which processes the weather forecasting data and of a decision-making model, which calculates the optimal route following priorities set by the ships owner. Finally, the routing system has a route recommendation feature, which translates the information into a series of waypoints read by the shipmaster. The SkySails system also improves the ships safety and performance on water as it damps the waves so that the ship suffers from less slamming and torsion forces. In addition, as a result of smoother sailing, the ships life is extended. A short video of a ship equipped with the SkySails system is available (http://www.maplesoft.com/company/casestudies/skysails.aspx) The steering system of skysail operates automatically meaning that there is no input need via crew, just observation. The skysail system will have a control pod situated on the high strength towing rope and the kite. This pod changes the profile of the kite such that it ultimately controls its flyting path in line with ship needed direction. Wind-Turbine: Wind turbines are widely used in land; however it has not yet been applied on at large scale in the shipping industry. Wind turbines at sea could perform two functions as electricity generation and in aid of propulsion. The drawback using wind turbine is it will be ineffective at no wind and counterproductive at high wind conditions.many smaller vessels have used wind turbines directly connected through gearbox to the propeller. But large vessels need large size machine to drive the generators which makes complex engineering to make it work stable. Also this system will need more time to get fitted, assembled such that it means it will be suitable for future vessels. APPLICATION OF WASP SYSTEMS: The use and development of WASP systems in the modern day shipping should be considered to make an adequate conclusion .At present WASP system are at very small percentage of the global marine transportation industry. The different types of systems are already present in use various ships and also in small vessels such that it makes easy to have a very good potential in upcoming years since the price of fossil fuels hikes and also they pollute the air which made global impact to cut the harmful exists of these pollution.by looking at the advantages and the usefulness of WASP systems and its drawbacks, various factors related to it can be analysed. The further topics will discuss about the advantages and applications of these systems. POTENTIAL OF PRESENT WASP IN PLACE: WASP is already in place for long ago in small vessels like boats in fishing industry. Currently WASP is present in less in global marine industry but its still considered as notable, potential system to avoid fossil fuels.by analysis the various factors and cases, understanding can be done greater. Oil crisis happened in 1970s and 1980s , the Japanese were very conscious and tried to look into alternative to the field of ship propulsion and some 17 sail- assisted tankers were produced with all having similar design. The first vessel with name Shin-Aitoku-Maru (DWT: 1600), in 1980 reached 11knots speed when the sea and ship conditions were good. These sails travelled in sea during that oil crisis but later the oil prices dropped down again .this made the diesel engines to overcome those sails and the marine industry discarded to use the systems .however the environmental concern arrived in 2010 regarding water and air pollution due to the fossil fuel .this play a massive role to change the world to look into alternative energy sources that can be used in sea and imposing rules and regulations on various pollution factors. APPLICATION OF WASP: The application of WASP systems are vastly used in fishing industry in smaller vessels. Many American and European boats have small auxiliary soft sails but they are used rarely. Large commercial fishing vessels does not utilise wind at all, since it would be impractical most often. They increase work load on crew with others factors including cost of the equipment and less knowledge to use the system of WASP will make it difficult to use it. It can be seen in statistics that WASP could be used in fishing fleet to a greater extent that actually works. By looking at historical research, wind has been used ad earlier way of propulsion when no engines exists. The transaction from the main form of propulsion changing from wing to coal- fire propulsion units took place so quick over a time spam of 30 years. However increase in price of fuel and pressure to reduce fuel consumption. Skysails are used by Wesselss Sipping Company on three vessels where some good results have ben obtained. WHERE WASP MAY BE APPLIED: Although climate change has occurred since the creation of the Earth today it represents a setback to a society that grew in the last two centuries to over 7 billion with an associated energy demand based primarily on the consumption of fossil fuels. The global population is expected to peak at 9.2 billion around 2075, while social development is desired to continue.so its important that WASP could be used in various ships propulsion. WASP may not be a good solution in making all vessels more efficient and reduce fuel consumption. But some vessels use the benefit of this systems.in recent years Ultra Large Crude Carriers (ULC) and Very Large Crude Carriers (VLC) dominates the transport of crude oil and the benefits of WASP on such kind of carriers are hard to be seen in practice. But smaller carriers may benefit from WASP technology and vessels which run on lower speed can use this type of propulsion to reduce fuel consumption. For example, steam coal and iron ore are usually stored on a very large scale before the resource is even utilised. In that case the vessels can carry them with the use of WASP which can produce 11-13 knots speed and its practicable. FACTORS One of the weapons used by all vessels, the WASP combat is essentially highly advanced missiles that contain a variety of sub munitions. The computer that controls each one is also able to analyse tactical situations and plot the best path to achieve your goal and ensure success. The WASP has a maximum acceleration of 20g when using standard fusion fuel. This acceleration and speeds allows the WASP conditions for manoeuvre and more power. This speed advantage and acceleration allows you to run more. In addition to attacking enemy ships or space stations, WASP combat can also be used as a defines drones. In this mission profile, WASP can also be used as thermonuclear warheads or anti-matter ahead of the enemy. The health and economic impacts In this area, we are only beginning to understand the true extent of the consequences on utilization of WASP systems. Intuitively there is an accumulation of pollutants through the food chain and possibly in our drinking water supplies. But, according to Technical Document Management Measures National Pollution Control Environmental Protection Agencies, published in November 2001, petrol, oil, diesel fuel, and batteries and acidic cleaning compounds, and solvents involved in the maintenance of the boats ( as methylene chloride, tetrachloroethene, trichloroethene, and trichlorethylene) trickle in lakes, rivers and coastal areas, and many of these pollutants, particularly some of the heavy metals are attached to sediments and are eventually found in the food chain through either plankton or other organisms and then concentrated through the food chain, being a major environmental threat as well as a big human health problem when it comes to fish consumption. The high speed of supply and refuelling system used by WASP does not mask the problems caused by liquid spills and toxic gases; rather, it completely solves the problems. Industry There are economic consequences for the marine industry. The short-term impacts that cause direct financial costs are cleaning and punitive actions associated with them. Over time, the waters are much polluted, further legislative measures are introduced. Clean water is essential for multibillion dollar industry. Environment Supply system by WASP system is a high-speed refilling helps the environment in many respects, eliminating damage caused by other products refuelling. This product eliminates the smoke harmful gas that gives off the oil, polluting the air. It eliminates the greenhouse gases that pollute the earth and our ozone layer. This system prevents leaks that harm the soil. There was never a supply system created before can eliminate all kinds of damage, and that works without causing pollution. The high speed of supply and refuelling system using the WASP does not mask the problems caused by liquid spills and toxic gases, however, solve them by complete. Most of the damage caused by the emission engines and oil leaks comes from petroleum. Small leaks, despite being isolated events tend to occur every day around the world, they are, gallons of oil pollution in our waters. A small fuel leak affects a disproportionate amount of water on the surface of the ocean. In the UK the legal limit leaking oil and one drop of oil for every 2 litres of water in a proportion of 15mg per litre. Therefore, a single litre of oil can contaminate one million litres of water. And this is a chronic problem to be solved, and the reaction of sunlight, the chemicals become infinitely more toxic, and prolonged exposure affects thousands of fish species and a myriad of creatures such as shellfish, marine plants and damage as algae and their reproduction when exposed to oil. And the old trick of using soap or detergents to make the brightness disappear, is not only illegal, but it only makes pollution worse, and eventually adding surfactants to the mixture, whic h attach to the gills of fish and destroy their ability to breathe. The effect is catastrophic. And, as if that were not enough, the increase in population drives the development of the industry, and a lot of pressure on the marine environment. The impact on marine life inevitably leads to an impact on human health. WASP Systems are specialized in projects for supply, installation and commissioning of water systems and wastewater treatment systems, gray water recycling, along with some simple write-downs and innovative energy systems. The system creates a vacuum seal ventilating, and dramatically reduces the incidence of unintended leakage of gas that would normally escape to the atmosphere. The main advantage of the invention is that it allows the filling very quickly, which will significantly reduce operating costs for operators of vessels and facilities loading terminals. Applications for the WASP system will focus initially on three distinct segments in the market within the maritime industry: nautical recreation, navigation and commercial refuelling (as tugs, barges, ferries and commercial vessels), and loading of liquid cargo from ships that cross oceans. The deployment of this system in the world will eliminate millions of tons of harmful particles of gas to the atmosphere, and prevent millions of gallons of fuel from spreading into watercourses .freighters with this product, which is able to increase the delivery time cargo 100% and thus may reduce the time spent in each vessel terminals. We can shorten the terminal for vessels which reduces the rate per ton of whole load of liquid therefore increase the amount of deliveries for all vessels. We can reduce the waiting time for vessels which reduces the rate per ton of whole load of liquid therefore increase the amount of deliveries to all ships refuelling and increased how it works at high speeds. Our product also eliminates many greenhouse gases and gases hazardous to health that are associated with refuelling which in turn becomes safer for everyone to use our product to refuel. Currently we are working together this time with a major oil company and help them in their oils movement worldwide. 6.2 Economic factors Economic factors in the application of WASP freighters These ships can perform rapid sustained combat operations at sea as a centrepiece strategy. To carry out its core mission, WASP has a support system that synchronizes the simultaneous horizontal and vertical flow of cargo and vehicles throughout the ship. The ship propulsion can generate a total of 400 tons of steam per hour. If the energy of the two boilers were converted into electrical current could power a city of 160,000 inhabitants. Electric generators aboard a ship can provide more than 16,000 kilowatts of energy. Two stations provide a capacity of 450,000 litres to 200,000 litres of water per day supply. Chapter 5: Case Study 5.1: MS Beluga Skysails MS Beluga Skysails with its computer-controlled kite (top right corner) One of the latest innovations in the heavy cargo ship which increases fuel prices has been a return to wind power. The MS Beluga SkySails is a heavy carrier that uses a towing kite system as part of its propulsion systems. The ship was launched and followed early sea trials in the North Sea in January 2008, the vessel embarked on its maiden voyage from Bremerhaven, Columbuskaje to Guanta, Venezuela. On route, the efficiency of the system was applicable in winds of up to force five for 8 hours a day. The system was hailed as a success, with calculated savings of up to 2.5t of fuel/$1,000 a day. With larger sails of 600m ², fuel savings can get up to 35%, possible. CONSTRUCTION The system has been developed by SkySails SkySails GmbH and Co. KG. The Beluga SkySails was equipped to navigate with a candle paraglider 160m  ². The area of à ¢Ã¢â€š ¬Ã¢â‚¬ ¹Ãƒ ¢Ã¢â€š ¬Ã¢â‚¬ ¹the kite can be increased to 320m ². A pipe controlled by computer, is connected to the ship by a system of rope. The system can control the kite at altitudes between 100m and 500m to maximize the benefit of the wind. With oil prices so high, a cargo ship 87m average could save about à ¢Ã¢â‚¬Å¡Ã‚ ¬ 300,000 a year. The system can potentially be adjusted to any ship. The overall reduction of carbon dioxide transport arrives at an estimate of considerable million tons per year. The BBC said there is something magical, a giant cargo ship being pulled on its way to the sea with ten thousand tons of metal, and with the sun shining giant masts. But there is something even more magical about the MS Beluga SkySails. On the face of it, this ship leading, for example, parts of a production line of wood to Venezuela looks like any other cargo ship. MS Beluga SkySails believes its fuel bill will be cut by  £ 800 ($ 1,560) a day. We can demonstrate that it is possible to combine economy and ecology, says Verena Frank of Beluga Shipping, and explains, Economy, because you can reduce consumption and fuel costs and, moreover, contribute to ecology, reducing emissions carbon dioxide. the kite is controlled by computers. a computer helps to make it fly, and maximize the power it produces, the other computer adjusts the direction of the kite. If the project is successful, we expect to see kites even higher very soon sum up to 5,000 square feet in size, pulling ships ac ross the seas and oceans. Graphic Steve Rosenberg explains, See how the ship kite works: of all the CO2 that is pumped into the atmosphere today, 4% comes from ships. Thats more than the aviation industry, mainly because 90% of world trade is done by sea. The MS Beluga SkySails believes it has the solution environmentally, with a mission to transform the green oceans. Once the ship reaches the open sea, reveals a new weapon in the fight against global warming: a kite. The 160m2 kite is hoisted on a mast and for half an hour or so, he stands there at the top of the mast, not making a big thing. The wind and certainly a wonderful thing, because it only needs a bit of wind to make everything else work. Half an hour later, however, the wind makes the kite start to fly hundreds of feet in the air and helping to pull the ship. The paragliding and synonym of power to the engines of the ship, so you can work on reduced power: which means less carbon emissions. It also means lower bills in fuel costs. With the price of trans portation fuel that has doubled in the past two years, paragliding promises great savings. How the Ship-Parrot The kite helps reduce annual fuel costs 10-35%. Fuel economy also means fewer carbon emissions harmful to the atmosphere. The large towing kite resembles a glider and is shaped like an airplane wing, so you can take advantage of different wind directions. The kite operates at 100-300m above the surface much larger than a normal sailing boat where winds are stronger and more stable. The kite can be used in winds of 12-74 km / h (or 7 to 40 knots).

The Future of Iptv and Ip-Video

ECE 6613: Broadband Access Networks The Future of IPTV and IP-Video Ji Hwan Kim Georgia Institute of Technology 325050 Georgia Tech Station Atlanta, GA 30332 Abstract— This paper describes the various IPTV architectures and components, which enables large-scale integration of current and future IPTV network. IPTV technologies are transforming how we perceive TV services today and global television industry as whole. However, there is pressing need for improvement on IPTV side to meet the Quality of Experience that is equal to or better than traditional TV services.In recent years, we have seen tremendous growth in Information Technology industry with the emergence of smart phone. Various new technologies are in its development to meet the demand of higher data rate, reliable data transfer, and readily available resources with distributed cloud servers to improve quality of service to the customers. With growing number of smart phone users, IPTV service has become ever more pop ular in telecommunication companies to provide streaming videos through the different new infrastructures.The biggest competitors in IPTV service in the U. S. are Verizon FioS (FTTP) and AT&T U-verse (FTTN) providing triple-play bundle service to the customer. In this paper, we are going to discuss IPTV service architecture difference of Verizon FiOS, AT&T U-verse, Cable Company, and Netflix as well as current IPTV research and development to increase quality of experience through multicast and cloud computing. Also we will analyze some of the emerging IPTV application in the future. Key Words — Internet Protocol Television (IPTV), Verizon FiOS, AT&T U-verse, MulticastIntroduction Today’s IPTV services IPTV technologies are transforming how we perceive TV services today and global television industry as whole. It is a collection of modern technologies in computing, networking, and storage combined to deliver high quality television contents through IP network. It is be coming a platform which changing how we access information and entertainment. In recent years, we have seen tremendous growth in video and networking technologies with the emergence of smart phone.Various new technologies are in its development to meet the demand of higher data rate, reliable data transfer, and readily available resources, distributed cloud servers, to improve quality of service to the customers. The figure below [1] is an example of IPTV broadband network inside a home. [pic] Fig. 1. Diagram of IPTV Broadband Network Inside Home. With IPTV service, video contents are not only limited to the TV but can utilize in multiple platforms to enjoy video content anywhere, anytime, and anydevice.IPTV alter the way the customer consume video content like personal video recorders have done and lets customer have complete control of their entertainment experience to a next level. [pic] Fig. 2. U. S. Multichannel Video Subscriber Census Above is a figure of U. S. Multichannel Vi deo Subscriber Census by SNL Kagan [2]. In 2011, the cable industry lost 1. 8 million video subscribers whereas IPTV providers gained 1. 6 million. This shows that IPTV industry is gaining market share on video content provider and it is expected to grow even more.Cable TV delivers entire line-up of broadcast content channels all the time which requires huge amount of bandwidth being delivered all the time into the home and cable companies are moving toward IPTV delivery services to reduce bandwidth on their infrastructure. IPTV architecture is very different in that it only delivers the single channel that is requested by the consumer’s individual TV. Therefore, IPTV architecture can greatly reduce bandwidth by only providing specific request from the consumer at any given time [4]. [pic] Fig. 3.Expected Growth in IPTV subscribers. However, there is pressing need for improvement on IPTV side to meet the Quality of Experience that is equal to or better than traditional TV ser vices. To provide great quality of experience in IPTV requires almost no packet loss, delay variation of 200ms, and delivery of no more than one perceivable error during a two-hour movie. This constrains and requirements puts heavy burden on service provider to provide reliable and lossless IPTV to customers and requires video admission control. The paper is outlined as follows.In Section II, we overview the different IPTV system and architecture exist today and how service providers are planning to improve their IPTV infrastructure. In Section III we will discuss the multicast protocol in depth and current research from Cisco to deliver IPTV service with multicast protocol. In Section V, we will discuss some of the potential future application that can be seen in near future with IPTV service. IPTV System and architecture IPTV networks generate their video contents for transmission using many clustered components collectively called headends.There are three common types of IPTV hea dends to meet national, regional and local content distribution requirements. Super Headends (SHE) receives and digests content on the national level typically from satellites. After processing and encoding, the SHEs distribute the national content to video hub offices (VHO) over a core IP/MPLS network. VHOs aggregate national, regional, and local content with the on-demand services, and serve metropolitan areas with a population of between 100,000 to 500,000 homes.VHOs are connected to video switching offices (VSO) over metro aggregation networks. VSOs distributed the IPTV streams to the customer premises over access network. The IPTV architecture is shown in Figure. 4. [pic] Fig. 4. End-to-End IPTV Network Architecture. The most conventional transport technique for IPTV is to multicast UDP/IP packets with MPEG-2 video compression scheme. The newer standard video architectures use RTP protocol which can provide error repair and stream monitoring unlike UDP protocol.IPTV service hav e slower channel change time compare to CATV service provider since all the TV channels are broadcasted simultaneously whereas IPTV needs to request certain channel from the provider. IPTV zapping time is affected by several factors such as Internet Group Management Protocol (IGMP) signaling delay of leaving and joining multicast group, MPEG decoding delay, program specific information (PSI) including program association table (PAT) and program map table (PMT) acquisition delay, random access point (RAP) delay, conditional access system (CAS) key acquisition delay, and de-jittering buffer delay in the STB [4].More detail of video admission control in IPTV multicast protocol will be discussed in Section III. IPTV service over a packet-switched network demands near zero packet loss and limited jitter. Thus, it is often necessary to enforce traffic management and admission control in IPTV network by sufficient provisioning and resource allocation [4]. More detail on resource allocation through retransmission server to improve IPTV will be discussed in Section III. Telco companies are embracing the IPTV technology since this will open up huge market share with Cable TV companies.Telco companies have been delivering packet-based IP traffic over their xDSL technology for many years and utilizing their existing technology to move to IPTV is a natural choice for them. However, there are great roadblocks to deploy IPTV over DSL which primarily concerned with quality of experience that is equal or better than traditional CATV. Below is the figure of IPTV infrastructure for Telco companies [1]. [pic] Fig. 5. Telco End-to-End IPTV Network Architecture. The primary difference in Telco companies’ architecture can be seen in red cloud shown in Fig. 5.Digital subscriber line access multiplexer (DSLAM) is located in environmentally controlled vaults or huts. It is also called video ready access devices (VRAD), which is placed on lawns or easements or a common space in a partment building. DSLAM often serves 100 to 200 residential gateways (RGs) that are attached to the outside of a residence and various techniques are used to transport signal between DSLAM and RG. Very high-bit-rate DSL (VDSL) for copper and broadband passive optical network (BPON) and gigabit PON (GPON) for giber transport. This metro access segment uses a hub-and-spoke architecture [5].Cable companies have been utilizing Hybrid fiber coaxial (HFC), combine optical fibers and coaxial cables, network since early 1990s to provide broadband internet access over existing cable TV system and its been employed this protocol globally and Data Over Cable Service Interface Specification (DOCSIS) is the international standard for developing equipment for HFC networks. Cable IPTV architecture is able to evolve from the traditional CATV with simple changes by adding few more components: cable modem (CM), cable modem termination system (CMTS), and a PacketCable Multimedia (PCMM).The cable comp anies’ architecture is shown in the figure below. [pic] Fig. 6. Cable Company Network Architecture. The CMTS and CM can provide a bidirectional IP over DOCSIS transport in the HFC network. CMTS can provide media access control (MAC) and physical protocol layer (PHY) in a single device by integrate with DOCSIS however, cable industry is moving toward a modular CMTS (M-CMTS). M-CMTS separates MAC and PHY layers to improve the scalability of DOCSIS transport.The CMTS manages DOCSIS QAM switching and provides QoS over the DOCSIS channel as well as manages residential CMs by dynamically load-balancing CMs among DOCSIS downstream channels to optimize traffic flow. PCMM policy server in DOCSIS networks defines admission control QoS policies by using session managers to request and reserve bandwidth for CMTS to enforce these QoS policies. A. Verizon Fios In 2004, Verizon began deployment of its Fiber to the Premises (FTTP) access network. The initial deployment used the ITU-T G. 983 BPON standard and in 2007, Verizon began using equipment with the ITU-T G. 84 G-PON standard. Fig. 6 below is Verizon’s BPON FTTP architecture diagram describing the connection between Optical Line Terminal (OLT) and Optical Network Terminal (ONT). OLT provides interface between Core network with voice, data, and video signals and Erbium Doped Fiber Amplifier (EDFA) boosts the [pic] Fig. 6. Verizon BPON FTTP architecture optical video signal. ONT performs the optical to electrical signal conversion and provide the data, voice, and video service to the subscriber. Wavelength division multiplexer (WDM) combines the three wavelengths onto a single fiber for transmission to the premises. 310nm wavelength is used for upstream traffic and for downstream, 1550nm (broadcast video) and 1490nm (data and voice) are being utilized. Fiber Distribution Hub (FDH) cabinet contains 1Ãâ€"32 passive optical splitters. Each subscriber is connected to a dedicated fiber between FHD and the premis es. BPON delivers 622 Mbps downstream and 155 Mbps upstream per PON for voice and data through ATM. FiOS provide over 600 channels between 50 to 870 MHz RF signal transmitted over the 1550nm wavelength. [pic] Fig. 7. Verizon FiOS RF spectrumGPON physical architecture is same as BPON however it provides significant improvements over BPON in bandwidth. GPON can provide 2. 5 Gbps downstream and 1. 2 Gbps upstream for data and voice and in addition, GPON have different transport by implementing Ethernet based protocol to transfer data instead of ATM. The comparison of BPON and GPON is shown in Table 1 below. [pic] Verizon uses Multimedia over Coax Alliance (MoCA) technology to provide data communication inside the resident. MoCA is installed in the ONT, Broadband Home Router, and set-top boxes and permits two-way IP data transmission over coax.By using MoCA, Verizon can reduce installation cost by using existing coax cable instead providing Ethernet cables to connect devices in the resi dent. [pic] Fig. 7. Verizon FiOS MoCA Verizon is using two main FTTP deployment schemes, the FTTP Overlay architecture and the FTTP Full Build. The [pic] Fig. 8. FTTP Overlay and Full Build Deployment Choice between two deployment scenarios is dependent on the specific deployment area and the likely take rates. In the FullBuild architecture, the fiber is deployed to each house and each subscriber gets an ONT together.In Overlay architecture, fiber is available to pass all homes and business in a distributed area but only a small percentage of homes and businesses are connected to and served with FTTP [7]. B. AT&T U-Verse In 2006, AT&T launched its U-Verse IPTV service (project lightspeed), comprising a national head-end and regional video-serving offices. AT&T offered over 300 channels in 11 cities through FTTN technology. AT&T utilizes copper pair to connect VRAD to Residential Gateway (RG) using xDSL technology. With U-verse, it can provide 25Mbps to home approximately 2500~4000 f eet away.By using MPEG-4 H. 264 compression technique, U-verse can provide 4 simultaneous TV stream (2HD and 2 SD TV), 2 VoIP and POTS service to the resident. Figure below is U-verse architecture. [pic] Fig. 9. U-verse FTTN Architecture The DSL technology at its beginning stages could only deliver 6 Mbps but now with ADSL2+ and VDSL, it can provide much higher bandwidth over a single copper pair. [pic] Fig. 10. xDSL technology. The various techniques are being implemented to improve the bandwidth and physical loop length capabilities of different DSL technologies.Bonding copper cable pairs can provide higher bandwidth by terminating 2 copper cable pairs together to act as 1 larger copper pair. ADSL2+ and VDSL is bonded together to provide higher bandwidth. VDSL can provide higher throughput than ADSL2+ however, it can only support short loop length. There is newest xDSL technology standard VHDSL2, which approved in February 2006, can provide bandwidth of 200 Mbit/s but maximum dist ance of 300 meters. xDSL technology goal is to provide VDSL speed with longer loop length [4]. The various different xDSL technology characteristics are shown in table below. TABLE 2. xDSL SELECTED CHARACTERISTICS. pic] AT&T typically uses mix of xDSL technologies to deliver broadband service to subscribers. Mainly ADSL2+ from the central office and VDSL2 from the VRAD through FTTN fiber based technology. C) Cable TV to IPTV Transition Cable companies are the largest subscription television service provider in the world and can easily integrate IPTV services to their existing infrastructure. In cable TV infrastructure, there are two main categories of digital video services: broadcast and on-demand Broadcast service defined as a service in which one copy of a program is sent to all subscriber in a broadcast manner.Broadcast services include : – Digital broadcast- Encoded/compressed programs are sent to a subscriber’s STB, where they are decoded/uncompressed for playbac k on a TV. All programs are transmitted regardless of which programs are currently watched by the customer – Switched digital video (SDV) – SDV is similar to digital broadcast but only requested programs are sent to a subscriber group. This group typically consists of all the subscribers served by HFC node which can serve range o 125 to 2000 subscribers. SDV is first two-way communication with subscriber for program selection.The digital broadcast architecture begins with the polling the content in the headend from satellite and terrestrial sources. The acquired content is generally forward to a multifunction media processing device performing following three functions: – Statmux – performs statistical time-devision multiplexing of real-time video content from various sources. – Groomer – adjust rates of content into a maximum bandwidth and limiting the rate of video burst – Splicer – inserts ads into programming breaks as need ed for a regional market. [pic]Fig. 11. CATV Architecture. The content is then forwarded across IP transport network to an IP-enabled quadrature amplitude modulator (QAM), where video content is encrypted and forward to STB for the customer. An out-of-band (OOB) channel provides the STB with basic tuning information, basic tuning information, decryption keys, software upgrade, and other communications. Switched Digital Video (SDV) was designed as a cost-effective method to expand bandwidth capacity in a way different than plant upgrades or better video compression method.Traditional digital broadcast sends all the channels into the HFC network but with SDV, programming terminates at the headend (VHO) or hub (VSO) and does not send channel unless it’s requested. When an SDV program is selected, tuning software in the receiver sends an upstream message and SDV session manager receives the quest and maps the program to a frequency within the allocated pool. If the program is alr eady being viewed within the same subscriber group, the task is as simple as reusing the existing session frequency information. On-Demand service is an interactive service where a requested video program is streamed to one subscriber.All on-demand content is encoded/compressed and stored on server to be received by individual subscriber’s request. On-demand services include following: – Video on demand- Content is stored on a server and subscriber views a list of titles and requests to view a specific title. The VOD system authorizes and streams the requested content to the requested user. – Network-based personal video record (nPVR) – this service is like home PVR except the content is on the service provider network. A subscriber uses the STB to record specific content to record and watches content at a user-chosen time which is same manner as VOD. pic] Fig. 12. Integrated Cable Video Service Architecture Cable IPTV architecture needs three newly added components to enable IPTV to their customers: Cable modem (CM), Cable Modem Termination system (CMTS), and a PacketCable Multimedia (PCMM). [pic] Fig. 13. Cable IPTV Architecture The CMTS and CM provide a two-way IP over DOCSIS transport in the HFC network. Cable Companies are moving toward M-CMTS technology, which can separate, MAC and PHY layer to improve scalability of DOCSIS transport unlike traditional CMTS where both MAC and PHY layer in a single device.In order to utilize IPTV in Cable company network, IP STBs or other IPTV capable devices must be able to receive video over IP transport and remove network delay variation. Major Cable companies are finding hybrid STBs as attractive solution for IPTV. The Hybrid STB with an embedded cable modem can receive video from either IP path or traditional QAM/RF transport path, which is good strategy to migrate from traditional cable architecture to IPTV. Admission control in Cable IPTV can be applied to both the IP network from the vi deo source to the CMTS, and the HFC network between the QAM and the CM through PCMM policy server.Policy server in DOCSIS networks defines QoS policies for CMTS to enforce them. Admission control signaling can be categorized as off-path and on-path. Off-path is when the control path is different from the data path and on-path signaling traverses the data path for bandwidth requests that use the commonly selected Resource Reservation Protocol (RSVP). In order to provide better IPTV services to the customers, Cable industry must improve bandwidth efficiency in the last mile. The biggest recent innovation to optimize available bandwidth is SDV but additional solutions are becoming more important as cable company transition to IPTV service.QAM sharing holds great promise of improving bandwidth efficiency without the need of major change in their current infrastructure. However, there are several factors contribute to the bandwidth efficiency of QAM sharing: †¢ Even if SDV and VOD h ave the same peak hours, a viewer is likely to receive only one service at a time. †¢ The gain of QAM sharing comes from the statistical advantage of a bigger QAM pool, shared by two or more services. †¢ Differing peak hours of DOCSIS and video service contribute additional gains.For instance, the spectrum allocated for DOCSIS commercial services during the day may by reallocated for video services in the evening. Dynamic QAM sharing is being realized through new technologies and standards for the following reasons: †¢ The DOCSIS M-CMTS architecture, which separates the DOCSIS MAC and PHY protocol layers. This allows the PHY layer (specifically the QAMs) to be dynamically allocated and de-allocated. †¢ The recent emergence of universal QAMs, which can function as either MPEG video QAMs or DOCSIS QAMs. †¢ Standardization in edge QAM resource management. pic] Fig. 14. Dynamic QAM Sharing with M-CMTS Architecture ERMI specifies several interfaces to an edge res ource manager (ERM). The ERM is a plat- form that manages and leases QAM channel bandwidth for all applications: †¢ ERMI-1 is an interface for edge devices to register QAM channels to the ERM and notify the ERM of any QAM failures or state changes. †¢ ERMI-2 is an interface for the ERM to bind the QAM resources from an edge device to the resource allocation request. †¢ ERMI-3 is an interface for the M-CMTS core to allocate QAM-channel andwidth from the ERM. Variable bit rate (VBR) video provides considerable bit saving compared to constant bit rate (CBR) video. WITH VBR statistical multiplexing, Cable Company can save as much as 30 percent of bandwidth by just varying the output data per time segment. Recently, DOCSIS 3. 0 was release to compete with Telco companies FTTx deployment and it is redefined the communication between cable modem (CM) located at subscriber premises and cable modem termination system (CMTS) at cable service provider’s network headend. D OCSIS 3. are design to allow channel bonding to boost up network throughput and number of bonded channel is usually 4 or 8. With DOCSIS 3. 0 standard, it can provide 300 Mbps download and 100 Mbps upload [8]. TABLE 3. DOCSIS 3. 0 Standards and Characteristics [pic] D) Netflix OTT IPTV System and Architecture Netflix is the leading provider of OTT on-demand internet video streaming in the US and Canada with more than 23 million subscribers. Netflix can stream out HD quality video with average bitrate of 3. 6 Mbps and it is single largest source of Internet traffic in the US by consuming 29. % of peak download traffic. [pic] Fig. 15. Netflix Architecture Designing large-scale network infrastructure to support fast growing video streaming platform with high availability and scalability is technically challenging. The Majority Netflix infrastructure used to be hosted in its own datacenter but recently resorted to the use of cloud services, Content Distribution Networks (CDNs), and other public computing services. Amazon AWS cloud is being utilized by replacing its in house IT infrastructure along with SimpleDB, S3 and Cassandra for file storage.Video streaming is distributed out of multiple content distributed networks (CDNs), UltraDNS, and a public DNS service is used as its authoritative DNS servers. Microsoft Silverlight is employed as the video playback platform for Netflix desktop users and Netflix manages to build its IPTV with little infrastructure of its own. †¢ Netflix data centers – Netflix uses its own IP address space for the host name www. netflix. com. This server primarily handles registration of new user accounts and captures payment information and redirect users to movies. etflix. com or signup. netflix. com. This server does not interact with the client when handling movie request and playback. †¢ Amazon Cloud service – Most of the Netflix servers are served from various Amazon cloud services and key functions are content ingestion, log recording/analysis, DRM, CDN routing, user sign-in, and mobile device support †¢ Content Distribution Networks (CDNs) – Netflix utilize multiple CDNs to deliver the video content to the subscriber. The encoded and DRM protected videos are stored in Amazon cloud and copied to CDNs.The three main CDNS are Akamai, LimeLight, and Level-3. These three servers provide same quality level content to all the subscribers. †¢ Player – Netflix employ Silver light to download, decode and play Netflix movies on desktop web browser. There are different players for mobile phones and other devices such as Wii, PS3, Xbox, Roku, etc. Netflix utilize Dynamic Streaming over HTTP (DASH) protocol for streaming. In DASH, each video is encoded at several different quality levels and is divided into small chunks. The client requests one video chunk at a time via HTTP.With each download, it measures the received bandwidth and runs a rate determination algorithm to deter mine the quality of the next chunk request. It allows the player to freely switch between different quality levels depending on the bandwidth of subscriber. TABLE 4. KEY NETFLIX HOSTNAME [pic] Netflix Client player have many functions to improve its performance and quality of experience (QOE). Netflix video streaming is controlled by instruction in a manifest file, which Silverlight client downloads. This metafile provides the DASH player metadata to conduct the adaptive video streaming capability.It is client-specific and generated according to each client’s playback and bandwidth capability. It is in XML format and contains several key pieces of information including list of the CDNs, location of trickplay data, video/audio chunk URLs for multiple quality level, and timing parameters such as time-out interval, polling interval and other data to provide QoE to users. Manifest files ranks CDNs to indicate which CDNS are preferred for content delivery. Trickplay is achieved by downloading a set of thumbnail images for periodic snapshot during network congestion [15]. IPTV multicasting protocolIn early IP networks, a packet could be sent either in unicast (single device) or broadcast (all devices). With multicast, single transmission for a group of devices is possible. Multicast transmissions enable efficient communication between groups of devices by allowing Data to be transmitted to a single multicast IP address and received by the group of interest. Multicast over IPTV network presents many challenges related to reservation of resource and maintaining quality of experience (QoE). Backbone can be built based on IP/MPLS and the routers can be enabled for multicast using IGMP protocols.Before going into detail of multicast protocol in IPTV, we will discuss multicast protocol in detail and how it can help IPTV through multicast mechanism. TABLE 5. IGMPV2 AND IGMPV3 MAJOR DIFFERENCE [pic] The IGMP was defined to allow a host computer to select a stream fro m a group of multicast streams a user request. Following is the basic functions IGMP protocol: †¢ Join: an IGMP host indicates that it wants to receive information from a multicast group to become a member. †¢ Leave: An IGMP host indicates that it no longer wishes to receive information from a multicast group. Query: An IGMP router can ask the hosts which groups they are member of. This is done to verify a JOIN/LEAVE request or to look for error conditions. Queries maybe be: o Specific Query: Asks whether the host is a member of a specific multicast group o General Query: Asks the host to indicate all groups that it belongs to †¢ Membership Report: an IGMP host tells the IGMP host what group it belongs to. This report can be either: o Solicit Membership Report: Sent in response to a QUERY o Unsolicited Membership Report: initiated by the client.In the IPTV network, each broadcast TV channel is an IP multicast group. The subscriber changes the channel by leaving one gr oup and joining a different group. IGMPv1 is not suitable for IPTV because it does not include an explicit â€Å"Leave† capability. The client will continue to receive all requested stream until the multicast router issues next query. The standard for IGMPv2 and IGMPv3 major difference is shown in Table 5. IGMPv2 supports Any Source Multicast (ASM) networks and which allows host to specify which multicast group it wishes to join.Most deployed IPTV clients supports IGMPv2. The Major enhancement in IGMPv3 is that it allows Support Specific Multicast (SSM). Host can specify the source address it wants to listen to. Here’s basic IGMP operation involving two devices: †¢ IGMP host (client or STB) – issues messages to join or leave a multicast group. The client also responds to queries from the multicast router. †¢ IGMP router – responds to the join and leave messages to determine if multicast groups should be forward out an interface. Periodic queries are used to discover from error conditions and verify requests.The IGMP router receives multicast groups either through the use of a multicast protocol such as PIM or static flooding. It is the termination point for IGMP messages and does not send any IGMP information to its upstream neighbors. [pic] Fig. 16. DSL Access Network IPTV Service In xDSL IPTV architecture, the subscriber initiates channel change requests and responds to status inquiries. The Routing Gateway (RG) at the subscriber’s site and DSLAM aggregate traffic from multiple subscribers in order to act on request from the STB.However, IGMP networks were not originally designed to have networking equipment between IGMP client and the IGMP routers. This creates some challenges to the multicast implementation: – Excessive multicast traffic: When delivering high bandwidth IPTV over broadband network, it is important to ensure that IPTV channels are forward only to those subscriber currently viewing them sinc e bandwidth is scarce. If the intermediate devices are unaware of IGMP flows then all multicast traffic is broadcast out all ports – Excessive IGMP traffic: Extra bandwidth is consumed as IGMP flows are broadcast to across the network.A single STB IGMP request can result in responses from thousands of IGMP peer clients. – Excessive time to Leave a group: With small spare bandwidth in broadband networks, Leave request often must be processed before additional join request can be served. To mitigate above challenges, several techniques are proposed and developed in intermediary devices: Local Replication, Proxy routing, Proxy Reporting, and Immediate Leave. Local replication, IGMP snooping from DSLAM, allows DSLAM to inspect incoming IGMP Join and Leave request and take appropriate action.If the channel being requested to view is already being received at the DSLAM, it will replicate the stream and forward to the subscriber. The DSLAM builds a table to track which channe l are being forwarded to each port. [pic] Fig. 17. DSLAM with IGMP Snooping Proxy routing works by allowing intermediate device (DSLAM) takes active role of terminating all IGMP flows. This makes DSLAM to act as IGMP host and responds to all incoming requests. DSLAM will recreate the IGMP request and use its own IP address as source.The major benefit of proxy routing is scaling since router is not aware of individual subscribers. [pic] Fig. 18. IGMP Proxy Routing Proxy Reporting reduces the number of IGMP packets flowing across the network by selectively dropping IGMP packets that are not need to be forwarded. The Proxy Reporting can be subdivided to two categories: Query Suppression and Report Suppression. Query Suppression reduces traffic between the DSLAM and the subscriber premises by having the DSLAM intercept and respond to IGMP queries sent by the router.DSLAM will never send a specific query to any clients and forward general queries only to those client receiving at least o ne multicast group. [pic] Fig. 19. Query Suppression. Report Suppression reduces traffic from DSLAM to the router by having DSLAM aggregate the response. The DSLAM can intercept IGMP reports coming from STB and forwards a summarized version to the IGMP router only when it is necessary. There are two categories of reports. Unsolicited membership reports are forward when first subscriber joins a multicast group or last subscriber leaves a multicast group.This tells router to begin or stop sending channel to this DSLAM. Solicited membership reports are forward once per multicast group. The DSLAM will aggregate multiple responses together into a single membership report to save bandwidth. [pic] Fig. 20. Report Suppression Immediate leave alleviate IPTV challenge to change channel rapidly. The standard IGMP Leave operation for channel change is as follow: – The STB sends a request to leave one multicast group – Router responds by issuing Membership Query to confirm the requ est. The STB responds with a Membership Report which does not include the multicast group By implementing immediate leave, STB can leave the multicast group by just simply sending a request to leave one multicast group [16]. [pic] Fig. 21. Standard IGMP Leave and Immediate Leave. The emerging IPTV deployments utilize Real-time Transport Protocol (RTP) in order to deliver media content. Unlike UDP, RTP protocol can provide sequence numbers to maintain packet ordering and detect losses, and timing information to determine network delay and synchronize timing between senders and receivers.RTP control protocol maintains session state between senders and receivers and report sender and receiver statistics bi-directionally [17]. The rapid acquisition is illustrated in the Fig 22 flow diagram below. [pic] Fig. 22. Rapid Acquisition Flow Diagram 1) The RTP receiver sends a Multicast Leave message to its upstream multicast router to leave the current multicast session and end the currently v iewed channel. 2) The RTP receiver sends a feedback message to the feedback target asking for rapid acquisition for the session it wants to join. In this feedback message, the RTP receiver can specify its specific requirements. ) The retransmission server receives the feedback message and decides whether or not to accept the request. If the retransmission server accepts the request, it sends a message to the RTP receiver that describes the burst that the retransmission server will generate and send, including the indication when the RTP receiver should join the new multicast session. The unicast burst stream consists of retransmission of a specific block of packets which will allow the RTP receiver to begin displaying video without waiting for a certain random access point to arrive in the multicast flow.If the retransmission server denies the request, it informs the RTP receiver immediately. 4) If the retransmission server accepts the request, it transmits the unicast burst data an d any additional message(s) needed to carry the key information about the new channel. The key information is used to prime the decoder inside the IPTV STB so that it can start decoding sooner. The unicast burst continues at a higher than natural rate until the unicast burst catches up with the real-time multicast flow. The sustainable burst rate depends on the access network link characteristics. ) At the appropriate moment (as indicated or computed from the burst parameters), the RTP receiver joins the new multicast session by sending a Multicast Join message to its upstream multicast router. 6) The RTP receiver starts receiving the multicast flow and completes the rapid acquisition. The STB will not join multicast session immediately with rapid acquisition since there would not be enough available left over on the access link. By utilizing unicast burst sent from the retransmission server o catch up with the multicast flow in a reasonable amount of time before joining to multicas t group allows faster channel switching capability rather than joining multicast group immediately [18]. Cloud Computing service in IPTV IPTV videos can be delivered to subscribers through various different network structures. For many years, Proxy servers have been utilized to decrease network traffic and delays through high speed and robust connection. Telco companies are looking for ways to keep service calls rejections to minimum through cloud service for on-demand IPTV service. Figure below shows on-demand IPTV service for cloud architecture. pic] Fig. 23. On-demand IPTV cloud services Video can be streamed from any of the virtual servers by load balancing among server and handle peak loads by avoid overload to achieve continuous, high utilization levels of servers. Virtual servers can provide low cost computing resources. The Virtual server acts like a dedicated server but it co-reside on a single physical machines acting as multiple physical dedicated server. However, if too many virtual servers reside on the single physical machine, services may face problem due to scarce computing resource per virtual server.Virtual storage through cloud computing allow easy share of resources among themselves. Physical storage is virtualized into virtual disk, which allows storage consolidation across heterogeneous vendors and protocols, enabled by dynamically growing and shrinking of storage through live migration, in the enterprise storage area network to be used by applications [22]. F uture application of IPTV The key to differentiating IPTV from traditional TV service of VOD and Network-based personal video record (nPVR) is the real-time interactive application and social TV.With FTTx or Gigabit Ethernet providing more bandwidth in broadband network allows new killer application to maximize the value of the IPTV service. A) SayUTV SayUTV service allows users’ participation into TV sports, discussion, variety show, and so on. SayUTV allow mixing their vide o and sources into provider’s content to allow maximum interactive and customize IPTV content. The subscriber can click participation button on SayUTV GUI. After service provider or host of the content allows his/her participation, the subscriber’s audio and video content is mixed into program’s content.All the viewer of the content can view the participant’s image and voice. [pic] Fig. 26. SayUTV Service System Architecture SayUTV service divides the role of users into three major roles: †¢ Controller – who creates a service session and has a control over that session. †¢ Participants – who joins the session and contributes his/her own multimedia content. †¢ Simple Viewer – who enjoys this service in a passive way [pic] Fig. 27. SayUTV Implementation. SayUTV is an advanced IPTV service, which combined with bidirectional multimedia communication technologies allowing interactive user-participation [20].B) IPTV Interacti ve Online Shopping In order for IPTV service provider to maximize the profit from IPTV service require smart ad insertion based on customers’ preference. TV series and sports media are well known for effective product advertisement aid. Apparels worn by a main actress of TV series or MVP sports athletes have greater potential for larger sales than conventional display by online shopping website. In order to provide customer’s shopping craving while watching TV series or sports event is to add additional information to the product description field such as TV series name, and character or athletes name.This will allow customers place some tags on that particular product through watching particular TV series or service provider can collect customers’ preference based on content and insert smart ad targeting each subscriber. [pic] Fig. 28. Shopperama Service Screen in Korea Shopperama is OTT provider in Korea providing series, which have broadcasted through a TV st ation, online along with smart ad insertion. The apparels worn by main actors and products inside the episode are displayed in a synchronized manner with video content as shown in Fig 25.This allows customer to shop for products very easily while watching TV series and reduce customer’s burden of trying to find particular product [21]. To improve interactive online shopping with IPTV service still needs many enhancements to fully flourish in E-business model. Behavior targeting content to users is estimate to be 20 billion dollar industry and in order for IPTV interactive online shopping to gain market share requires smart integration of cross layer platforms. C) Final Remarks With IPTV service deployment, Cable Company is afraid of cord-cutting case.The IPTV service is gaining popularity amongst consumer and there are many opportunities for new killer application to integrate with IPTV service. In this paper, we described current IPTV architecture in the market and presented recent efforts to improve IPTV technology. Emerging IPTV mobile systems are also gaining a lot of attention and consumer trends demonstrate that IPTV will continue to be in demand. Acknowledgment I would like to thank Prof. G K Chang for giving me an opportunity to work on this topic and learn more about multicast protocol to provide IPTV service.I was able to learn more about IPTV architecture and current trend in network research in video streaming protocol.
