Terrestrial Digital Broadcasting Convergence and Implication

Terrestrial Digital Broadcasting Convergence and Implication Reza Tadayoni*, Knud Erik Skouby Center for Tele-Information, Technical University of Denmark, Building 371, DK-2800 Lyngby, Denmark Abstract This paper is a contribution to the development of analyses of the process of converging media and to the  clarification of the regulatory implications of this process. It is generally agreed that the process of  convergence between telecommunications, IT and broadcasting through its technological, organisational,  and market/service aspects has far-reaching inßuence on the sectors involved and on future socio-economic  settings. The paper explores the preparation for introduction of terrestrial digital television in Denmark as an  aspect in the general process of convergence. The explorative analysis establishes an understanding of the  technological issues and drivers in the development, which in interaction shape a digital distribution  structure that is a concrete part of convergence. Based on this understanding, a model à  the OSA-model à  is  suggested for the techno-economic structure of distribution of terrestrial digital TV. The model is used to  dis cuss market prospects and regulatory implications, as these are derived from the interplay of traditional  areas of regulation in the three sectors and areas emerging as candidates for regulatory activity based on their  functionality. The discussion of the process of introduction of terrestrial digital TV in Denmark thus provides  a general analysis of convergence and its regulatory implications. ( 1999 Elsevier Science Ltd. All rights  reserved. Keywords: Terrestrial digital broadcasting; Convergence; DAB; DVB 1. Introduction During the past few decades the communication landscape has been subject to radical changes. Traditionally, communication has been divided in three sectors à  telecommunication, broadcasting  and information technology (IT) à  which cover di ¤erent communication applications. The sectoral  0308-5961/99/$ à  see front matter ( 1999 Elsevier Science Ltd. All rights reserved. PII: S 0 3 0 8 5 9 6 1 ( 9 8 ) 0 0 0 8 6 X 1 This work is a result of participating in two Danish research projects: Service development, Internationalisation and Competences (SIC) project. Distributed Multi Media (DMM) project. 2DAB and DVB is used for digital audio broadcasting and digital video broadcasting, respectively, without reference  to the speciÞc European technologies/protocols-agreements using DAB and DVB as brand names.   Division has been based not only on di ¤erent technologies being used in the di ¤erent sectors but it  has also evolved in close interplay between political-regulatory interventions, economic considerations  and technological characteristics. Understanding the di ¤erent aspects of regulation in the information age requires a solid  understanding of the development in the communication landscape as well as of the ongoing  process of convergence between the traditionally separate forms of communication and of the  Ãƒâ€information fusionÕ. Technological speciÞcity has not been determining for sectoral division and is  not determining for the convergence process but it has been a vital factor in this process. Technological innovations like digitalisation, audio and video coding technologies, computerisation  and broadband infrastructures à  such as cable and satellite networks à  make service  provision across the sectoral boundaries possible. This also imposes new political and regulatory  challenges and makes re-thinking and re-designs of the existing regulatory framework for communication  a necessity. This paper1 discusses digital broadcasting as an instance in the convergence process where this is  seen as a process with technological, economic/structural and regulatory aspects. Within digital  broadcasting a focused area namely the terrestrial digital broadcasting in Denmark will be studied  in details. Broadcasting is quickly moving into the era of digitalisation as digital audio broadcasting  (DAB)2 and digital video broadcasting (DVB) to replace traditional analogue broadcasting  technologies. Full digitalisation of the whole production chain, from recording and editing over  transmission media to receivers in the end usersÕ homes, will be a reality in 10 to 15 years. This is  a challenging and extensive change that will face broadcasters, politicians and regulators in the  coming years. The main political and economic focus is generally on DVB and the transition has  already started in some European countries, most notably the UK and Sweden. For users, DAB/DVB will o ¤er many advantages over analogue broadcasting, such as better  technical quality, more programs and services on a given set of frequencies, and the option of  multimedia and interactive services. This development is an expression of converging media:  DAB/DVB will integrate elements from several di ¤erent media, computers, telecommunications  and broadcasting. The shift to digital broadcasting is not simple, however, as it introduces a range  of interrelated political, economic and technical challenges. Some of these challenges are speciÞc to  the mode of distribution à  satellite, cable or terrestrial with the latter having special problems and  potentials. As the basic technologies are now ready, solutions to two sets of regulatory issues are pertinent  for the development and di ¤usion of terrestrial DVB. One set of issues is related to the concept of  Public Service Broadcasters. In almost all countries, cultural policy considerations have given  rise to privileges and obligations for a few broadcasters.

Just War Theory :: Free Essay Writer

Just War Theory Questions About The War I think the just war tradition is a great way to rate if a war is really worth fighting or is it really not worth fighting. For the first law Just Cause, yes I would say that we as the United States have just cause to end the terrorist attacks because it is really starting to get out of hand. The Second law Comparative Justice yes I would say that we have comparative justice because we have definitely suffered more than Afghanistan because we have lost many more people in their attacks than they have in any of our attacks. The Third Law Legitimate Authority is definitely being used in our country to begin our war against terrorism. Our highest rank is the president and he is the one that did declare war against terrorism. The Fourth Law Right Intention, yes I do think that right intention is being used because they killed 4500 of our citizens and all we are doing is wiping out terrorism not necessarily killing any people. We as a country just want to out do the terrorist actions and bring peace to all countries. The Fifth Law Probability of Success, yes I think that the probability of success is greater than the probability of success for the terrorists. The probability of success against terrorism is greater to prevail because the United States and Britain are just taking the initial step and if any thing goes wrong the United States has 90% of the other countries around the world to help us if we need them. The Sixth Law Proportionality is being put in effect that they keep the civilian casualties down to a minimum because that is not the purpose of the war and after the war the will have out done evil and the good and peaceful will prevail.

Steve Jobs Personality

Type Today marks part four of our 16 part series exploring the sixteen Myers-Briggs Type [email  protected] test personality types and related notable Celebrity figures throughout time. Previously we examined Celebrity John D Rockefeller and the [email  protected] test EST] personality type. This week we examine the SITS (Introversion-sensing-Thinking- Perceiving) and the late great mastermind behind the â€Å"Apple†, Steve Jobs. Most people remember Steve Jobs as the co-founder and CEO of Apple Inc and Paxar Inc.Steve Jobs was also an individual that mastered his AMBIT type, the SITS, allowing him o excel in a unique position in his industry that lead to technical advancements that we often take for granted in this day of age. Like many Myers-Briggs Type Indicator Introverts who prefer thinking and sensing, Steve Jobs used his preferences primarily internally to analyze the data he gathered in an organized fashion much like the computers he helped develop. He was able to detach and objectively criticize the projects he worked on.This sometimes insensitive approach to problems was a double edged sword that lead to Jobs being fired from Apple in 1985 after losing a rower struggle with Apple's board of directors. Fortunately, Steve Jobs didn't give up, and utilized his Perceiving preference to remain flexible and spontaneous in his approach to work. He acquired the computer graphics division from Localisms and turned it into the critically and financially acclaimed Paxar Studios. He also started up NeXT Inc. That was acquired by Apple Inc. In 1996, and over the next four years Steve Jobs ascended to CEO of Apple bringing him full circle with the company.Steve Jobs also showcased how SITS types focus on efficiently working on projects and was a rim believer in doing only what was needed with the least amount of fuss. Efficiency and innovation were key focus points throughout his career. You can see this today in the products that Apple releases. From th e mimic, to the pod, to the phone, all three are innovations which are streamlined, clean, and efficient products that attract a full spectrum of customers. Apple produces a set amount of products that are mass produced for cost efficiency and quality control.This has allowed Apple to control the image of all the products they produce unlike open sourced platforms like he PC. This did not come without risk as many manufacturers looked down on Apple for their lack of flexibility in the ass's but it is that exact mentality of adaptable, action- orientated risk taking that is synonymous with SITS personality types. Not many people got to know the man behind the keynote speeches closely while he was alive. This is something that is common with Introverts. Most accounts were from people that worked for Steve Jobs. At one point Fortune named Steve Jobs â€Å"one of Silicon Valleys leading egomaniacs.He was also known as a demanding perfectionist, but that was a side effect of the extreme SITS preference that is often seen as confident, independent, and self-determined. Steve Jobs set the bar high and worked until the very end to meet those standards. In the end Jobs did things his own way. Through his successes and failures he changed the technical landscape forever and showed what a motivated SITS can achieve. – See more at: http://carcinogenicity's.

Diabetes

Diabetes DIABETES PAGE \* MERGEFORMAT 1Running head: DIABETESDiabetesDiabetesDiabetes is a common metabolic condition that results from elevated blood sugar levels. Diabetes is medically described as diabetes mellitus. This condition is known to cause underlining problems in individuals who acquire the disease. This condition is usually described as a combination of many diseases that eventually causes individuals to have high blood sugar (Parsaik et al., 2010).High blood sugar is attributable to inadequate production of the insulin hormone, which is a hormone, glycogen, responsible for regulating the blood sugar. Additionally, blood sugar imbalances can result from failure of the body cells to respond to insulin hormone. The insulin hormone is produced in the pancreas hence the condition is usually a defect of the pancreatic cells (Cook et al., 2008).Diabetes exists in three main types Diabetes type I, Diabetes type II, and Gestational Diabetes. The symptoms of each are attributable to the effects and the mode of occurrence of the type.Ulcus bei Diabetes à ¼ber dem HalluxThis paper provides an elaborate insight on diabetes and how it affects the body systems and metabolism. Moreover, it discusses how the condition can be properly prevented, managed and solved in critical cases (Glasgow et al., 2012).Type I Diabetes MellitusThis condition results from a metabolic failure. The condition is seen when the pancreas fails to produce hormone insulin. The human body is strictly dependent on insulin in order to reduce the sugar levels. Failure of the body to produce insulin will make the sugar levels in the blood uncontrolled making the sufferers to start developing the diabetes symptoms. Type I diabetes can only be treated when individuals inject insulin into their body systems. It is also known as Juvenile or Insulin Dependent Diabetes Mellitus (IDDM). Type I diabetes is not very common and is...

A Chapter Of My Life Essays - Indian Films, New Delhi India

A Chapter Of My Life Essays - Indian Films, New Delhi India A Chapter of My Life "God helps those who help themselves." This sounds like a simple passage from a religious book, but it has an overwhelming significance in my life. This phrase is greatly responsible for building self- esteem and confidence in me. It can also be credited for transforming a shy, introverted, and confused boy into a very confident and enlightened adult. I neither read the phrase from a book nor heard it at a religious service. I heard these words from someone who really understands the meaning of the phrase. That person's name is Ameet Handa. Ameet is suffering from multiple disabilities. I met him at the institution for the Disabled People in New Delhi, India, where I was sent by the school I was attending in India, to observe and understand the lives of people who are incapacitated. At that time I was on the high school cricket team and I was having problems with my shoulder, which was dislocated from the joint. This incident happened while I was playing cricket with my teammates. I was a fast bowler and my team needed me to win one game in which I hurt myself by throwing the ball. I did not play cricket for almost one year. After one year the school wanted me to play cricket and I played one game. I did not have any problem in that game, but in the second game I broke my hand so badly that I could not lift any we! ight with my hand. My school sent me to the All India Institute of Medical Sciences (AIIMS) in New Delhi, which was the best hospital in India, for surgery on my shoulder. There I met Ameet Handa who was 20 years old. Ameet was a person of charming personality. In spite of his multiple disabilities, I always saw him smiling. We soon became good friends. The first week before the surgery, when they were treating my shoulder the only place I was aware of was my room in the hospital. One day Ameet came up to me and said, "Bhavesh, what is wrong with you, I have never seen you smile." I told him everything about my shoulder condition, and how I felt about it. He did not say anything at that moment, but after few hours he asked me to accompany him on a trip within the institute. What I saw during that trip was unbelievable. I saw many people whose physical disabilities were worse than mine. There was a girl who was learning to type with her toes, and there was another blind young man who was working on some machine. Ameet looked at me and said, "The difference between you and these people is that you have conceded the battle, and they are still fighting, and many of them are winning the battles of life." He also said that if I thought that I could not do anything, there was no way I could achieve anything in my life. He said, "God helps those who help themselves." This trip opened the closed door of my mind. I realized that life is too precious to waste by worrying about the things that are beyond my control. Ameet's inspiration and the support of my family, friends and teachers have contributed in the success I have achieved. Due to the surgeries, which were performed on my shoulder about six years ago, my shoulder improved a lot. I do not! know what my life would have been like if I had not met Ameet. The first moment after the surgery when I opened my eyes, I did not feel my hand moving. I cried for that moment until the doctor said that my shoulder was fine, but also he told me that I could not play again at least for next six month. I was so happy that I could play again. The one thing I am not happy with is that I can not bowl as fast as I used to bowl. I started playing again after three months, but I miss those days when I was hero of my high school. Life is too short to waste on unimportant matters. I now enjoy every moment of

The Future of Terrorism Essay Example | Topics and Well Written Essays - 1500 words

The Future of Terrorism - Essay Example t governmental agencies, including the CIA, FBI, and FEMA to work collectively, and sort out effective tactics to be immediately implemented for combating terrorism (Ward, Kiernan & Mabrey, 2006, p.2). The Future of Terrorism Task Force is also a part of the US government’s strategic foundations on protecting America, and was created for predicting the status of terrorism in the coming years. The main task for this force was to accumulate evidence regarding the scope of terrorist activities in future, and then develop effective policies and recommendations for the Government to prevent upcoming attacks from happening. The January 25, 2007 report contained guidelines for the next five years. This paper is aimed at reviewing this report presented by the Future of Terrorism Task Force. â€Å"In designing homeland security policies, uncertainty about the forthcoming threat creates a number of problems. If we do not know the scale and nature of future threats, deciding how many resources to devote to homeland security efforts and choosing among different security measures is difficult† (Jackson, 2008, P.11). This explains the reason behind the creation of a proper task force to assess the future of terrorism and determine the most effective actions to counter terrorism. In the report, firstly the areas of weaknesses have been acknowledged and presented before the DHS to evaluate and respond, which is commendable (Security & Council, 2007, p.3). That is because first-hand knowledge and an in-depth analysis of the areas to work on will not just ensure the workability of these recommendations but effective policy management too. Another point to be noted is that the task force has covered every aspect of probable terrorist attacks, ranging from reviewing al-Qaed a’s future status to cyber terrorism and state-sponsored terrorism possibilities (Security & Council, 2007, p.3). This provides an overview of the diversity of ways the nation could be attacked along with

Instructional method and comprehension Essay Example | Topics and Well Written Essays - 2000 words

Instructional method and comprehension - Essay Example Thus, the terminology of ‘classroom management’ introduced in education with the objective is to create a positive relationship not only between teachers, but also among the peers themselves, and also to help those students who need psychological help (Stough & Emmer, 2001) The two domains of Instruction and learning play the most important role in the learning process of an individual. Instructional and learning style approach is discussed below. 1 Instructional method Methods are the means for instruction for the students. Mostly, instruction method depends upon the content, the students and the level of intellect of the students. Content is categorized into three main domains of knowledge, i.e., skills, attitudes, and values. According to the content and a set goal, students are made to engage themselves actively in the learning process. While, teaching skill, it is necessary to alter the content giving the learners more practical exposure and pointing out the important practical aspects. When teaching attitude, those methods are used which are required to apply in particular situations. There is several level of learning the knowledge of the content from simple recitation without complete understanding to learning so well that the learner has full understanding of listing, discussion, analysing, practical application, and extrapolation of the knowledge in a naà ¯ve situation (Bloom et al., 1956).
