Glenn Reitmeier, David Samoff Research Center Will Stackhouse, Consultant Craig Van Degrift, National Institute of Standards and Technology INTRODUCTION A workshop was held May 10-11, 1994, in Washington DC, to highlight technical issues for industry and government decision makers with respect to Advanced Digital Video (ADV) in the National Information Infrastructure (Nil). The purpose of the workshop was to: (1) define a vision of the role of digital video within the Nil, (2) identify the architectural, scaling, and performance issues in realizing this vision, and (3) recommend the research, experiments, and steps to be taken to resolve these issues. The workshop was attended by approximately 180 people from industry, government, and academia and consisted of talli and discussions by experts in information services, broadcasting, computing, consumer electronics, and government policy. Robert Kahn of the Corporation for National Research Initiatives, Michael Nelson from the Office of Science and Technology Policy, and D. Joseph Donahue, Senior Vice President for Technology and Business Development, Thomson Consumer Electronics, Inc. were among the many speakers at the Workshop. The discussions were facilitated by participants forming four breakout groups to focus on architectural considerations, modular decomposition and interoperability; display performance; image capture and display requirements; and digital delivery services. In addition, there were three demonstrations of new video technology. The Grand Alliance demonstrated three of the proponent high-definition television systems (HDTV) that have been incorporated into the Grand Alliance proposal to the Federal Communications Commission for adoption as the U.S. broadcast standard. Nippon Television (NTV) demonstrated a 525-line, 16:9 widescreen, progressive-scan television camera which offers improved picture resolution compared to today's television standards. And, NIST demonstrated the Mosaic/World Wide Web information retrieval system on the Internet, a possible model for advanced information retrieval within the NIL This summary by the Program Committee reports on some of the important ideas expressed by the speakers and the conclusions reached by the breakout groups. Discussion of an item in the KEY CONCEPTS section does not imply that the view was 1 universally accepted by the workshop participants, rather that it was expressed by one or more of the speakers. The Recommendations are based on the plenary discussions including two straw polls. The Breakout Group summaries (starting on p. 5) are a synthesis by the Program Committee of the reports from each group. The Breakout Group reports (starting on p. 11) appear without editing by the Program Committee. Speakers' slides and other contributions from the participants appear as an appendix. KEY CONCEPTS Definition of the National Information Infrastructure system to deliver to all Americans the Information they need when they want It and where they want It - at an affordable price, ” —Michael Nelson, OSTP The Nil will be an amalgam of information networks, appliances, and services. It will consist of thousands of interconnected, interoperable communication networks, including terrestrial and satellite broadcasting, cable television networks, wired and wireless telephone systems, commercial computer network services, and the Internet and its successor. Computer systems, televisions, telephones, and other devices will all converge to serve as "information appliances" on the Nil. Digital libraries, information services, and databases will be needed to provide the Nil information content; users will buy content, not technology. Content and useful applications will attract the usage necessary for Nil success. The cultural industries, particularly motion pictures and television, can thus be seen as an essential part of the NIL It is critical that intellectual property rights associated with cultural items be protected by audit and control mechanisms at all service levels. Furthermore, the Nil should be open to all information suppliers on an equitable basis. Nil applications will include distribution of entertainment programming, educational information, government data, manufacturing information, and access to health care. The production and distribution of entertainment programming today is a $37 billion information industry in the United States. Digital program delivery over interactive networks will permit additional cost-effective services such as video-on-demand and shopping at home. Electronic distribution of educational material will expose all students, even those in remote locations, to a high-quality education. Government, in part, is a vast information gathering and disbursing system. Electronic availability will facilitate access

They may be offered to those who are at high risk of cardiovascular disease and need to improve their diet, increase physical activity, stop smoking, or reduce alcohol consumption. Despite the popularity of these interventions, there is no overall summary and comparison of the effectiveness of different modes of delivery of a digital intervention to inform policy. Objective: This review aims to summarize the effectiveness of digital interventions in improving behavioral and health outcomes related to physical activity, smoking, alcohol consumption, or diet in nonclinical adult populations and to identify the effectiveness of different modes of delivery of digital interventions.

  • Content Is Not King
    Content is not king Andrew Odlyzko AT&T Labs - Research [email protected] http://www.research.att.com/ amo Revised version, January 3, 2001 Abstract The Internet is widely regarded as primarily a content delivery system. Yet historically, connectivity has mattered much more than content. Even on the Internet, content is not as important as is often claimed, since it is email that is still the true “killer app.” The primacy of connectivity over content explains phenomena that have baffled wireless industry observers, such as the enthusiastic embrace of SMS (Short Message System) and the tepid reception of WAP (Wireless Application Protocol). Combined with statistics showing low cell phone usage, this also suggests that the 3G systems that are about to be introduced will serve primarily to stimulate more voice usage, not to provide Internet access. For the wired Internet, the secondary role of content will likely mean that the dangers of balkaniza- tion are smaller than is often feared. Further, symmetrical links to the house are likely to be in greater demand than is usually realized. The huge sums being invested by carriers in content are misdirected. 1. Introduction The Internet is widely predicted to produce “digital convergence,” in which computing, telecommuni- cations, and broadcasting all merge into a single stream of discrete bits carried on the same ubiquitous network. The popular images of convergence are heavily tinged with the flavor of Hollywood. “Con- tent is king” is the universal buzzword, where content is usually taken to mean professionally prepared material such as books, movies, sports events, or music.

  • Advanced Broadcast Media
    Introduction to Broadcast Media (Notes) Tutorial Cutting to the chase: Broadcast media is radio and television. Even amidst the pop culture dominance of the internet, broadcast media still commands the largest share of the advertising pie nationwide. Put the audio and visual media to work for you as your company earns larger market share, stronger branding, and increased sales. If you are looking for cost-efficient lead generation, you need to be looking at radio and television advertising. Not only are radio and television the main media for advertising today, they are continually developing new ways to reach their audience. The SyFy cable network launched a show (“Defiance”) that combines interactions on a video game with the plot of a series show. Radio stations are supplementing on-air campaigns with digital media to provide on-air and on-screen promotions to those who stream the station through their computer. Multiple studies have shown that combining radio and television can help advertisers reach audiences not achievable with only one medium or the other. Broadcast Media Broadcast television Cable television On-demand television TV/web integration Local, network, and national radio On-air endorsements Long-form programming Multi-language programming The Power of Radio Radio reaches more Americans than any other advertising media. As an example, let’s look at Los Angeles, CA. It is the #1 radio revenue market in the world and generates more than $1 billion dollars in sales each year. In that market alone, more than 9 million people listen to radio each week. People are loyal to radio and love listening to their favorite DJ or talk show host.

  • Who Are Children with Visual Impairment
    New Mexico Directory of Resources for People who are Blind or Visually Impaired 2008/2009 Editor: Sherri D. Lyle Distributed by: New Mexico School for the Blind and Visually Impaired 2 January 1, 2008 As Schools for the Blind around the country move forward into the 21st century, it is increasingly clear that it does, indeed, “take a village” to raise a child. When that child is blind, the village, by necessity, becomes even larger. While New Mexico School for the Blind and Visually Impaired continues to have an integral role in the education of many of New Mexico’s children, many other services can be provided through the resources listed on the following pages. As local school districts begin to develop their own services in the field of vision impairment, this resource can help locate services, find an expert in the field or provide a contact for a family seeking information. We invite you to consider this a working document; if you identify other areas that should be included, or if you have resources of your own that you would like to share, please contact Sherri Lyle with your ideas. Changes, additions, corrections can be made by contacting Sherri at [email protected]. We look forward to continuing our shared journey with you as together we seek the best for our children in New Mexico. With that end in mind, we offer the 2008-2009 Directory of Resources for your use. Sincerely, Linda M. Lyle, Superintendent New Mexico School for the Blind & Visually Impaired New Mexico Directory of Resources for Individuals who are Blind or Visually Impaired 2008/2009 Sherri D.

  • Management of Radio and Television Stations in Nigeria
    New Media and Mass Communication www.iiste.org ISSN 2224-3267 (Paper) ISSN 2224-3275 (Online) Vol.10, 2013 Management of Radio and Television Stations in Nigeria I.W. UDOMISOR • Associate Professor in the Department of Mass Communication, University of Maiduguri; Borno State, Nigeria. • ABSTRACT Broadcasting is very important in Africa because majority of Africans get their information, education and entertainment chiefly from radio and television. Because of this vital role of broadcasting in developing countries, radio and television mediums have become the most controlled for both technical and political reasons. The study aimed at critically examining the role of government in the management and control of radio and television stations in Nigeria, its policy thrust and impact on editorial and programming independence. The study also examined how government strict monopoly affects programming content which in turn also affects political, social and cultural development of the country. The study relied mostly on historical data generated through documentary sources for analysis. The study found out that mass media policy which affects media management in Nigeria has been a sensitive, undecided and unconcluded phenomenon, not only because of diversity of the Nigerian society but also because of the failure of majority of Nigerians and their leaders to visualize the role of their mass media in the development of Nigeria. Mass media development in Nigeria has not only been painstakingly slow and erratic but has also followed the western pattern. The study therefore recommends that government must regard the media industry as an agglomeration of stakeholders all of whom are important to the business.

Subscribers included clerics, diplomatic staff, and noble families. Older folks listen more to the radio. Episode 1. The Inter Press Service , founded in , has served as an intermediary for Third World press agencies. As Schudson has given emphasis to, the answer is not easily found; "the ground journalists walk upon is shaking, and the experience for both those who work in the field and those on the outside studying it is dizzying". These were carved in metal or stone and posted in public places. This is precisely the key to the existence of a network relationship: the parties were dependent on the resources controlled by both parties, both goods and information, so by mutual co-operation both parties gained mutual benefits. Journalists should be honest and courageous in gathering, reporting and interpreting information. It used Arabsat to broadcast.
