Transformative Choices: A Review of 70 Years of FCC Decisions Sherille Ismail FCC Staff Working Paper 1 Federal Communications Commission Washington, DC 20554 October, 2010 FCC Staff Working Papers are intended to stimulate discussion and critical comment within the FCC, as well as outside the agency, on issues that may affect communications policy. The analyses and conclusions set forth are those of the authors and do not necessarily reflect the view of the FCC, other Commission staff members, or any Commissioner. Given the preliminary character of some titles, it is advisable to check with the authors before quoting or referencing these working papers in other publications. Recent titles are listed at the end of this paper and all titles are available on the FCC website at http://www.fcc.gov/papers/. Abstract This paper presents a historical review of a series of pivotal FCC decisions that helped shape today’s communications landscape. These decisions generally involve the appearance of a new technology, communications device, or service. In many cases, they involve spectrum allocation or usage. Policymakers no doubt will draw their own conclusions, and may even disagree, about the lessons to be learned from studying the past decisions. From an academic perspective, however, a review of these decisions offers an opportunity to examine a commonly-asserted view that U.S. regulatory policies — particularly in aviation, trucking, and telecommunications — underwent a major change in the 1970s, from protecting incumbents to promoting competition. The paper therefore examines whether that general view is reflected in FCC policies. It finds that there have been several successful efforts by the FCC, before and after the 1970s, to promote new entrants, especially in the markets for commercial radio, cable television, telephone equipment, and direct broadcast satellites. -

High Frame-Rate Television
Research White Paper WHP 169 September 2008 High Frame-Rate Television M Armstrong, D Flynn, M Hammond, S Jolly, R Salmon BRITISH BROADCASTING CORPORATION BBC Research White Paper WHP 169 High Frame-Rate Television M Armstrong, D Flynn, M Hammond, S Jolly, R Salmon Abstract The frame and field rates that have been used for television since the 1930s cause problems for motion portrayal, which are increasingly evident on the large, high-resolution television displays that are now common. In this paper we report on a programme of experimental work that successfully demonstrated the advantages of higher frame rate capture and display as a means of improving the quality of television systems of all spatial resolutions. We identify additional benefits from the use of high frame-rate capture for the production of programmes to be viewed using conventional televisions. We suggest ways to mitigate some of the production and distribution issues that high frame-rate television implies.

Public Service Broadcasting in Transition: A Documentary Reader Abstract This is a book of documents, comments, and cases that has been prepared, at the request of the European Institute for the Media, for the use of government officials and citizens interested in strengthening public service broadcasting in transition societies. In this book we try to provide a small chest of tools and background information that will be of assistance. We start, in Chapter 1, with an overview of some of the general principles of public service broadcasting, and include pertinent comments on each of them. Here, as throughout the book, we concentrate on issues of governance and financing, with some attention as well ot issues surrounding programming. In Chapter 2, we turn to current issues in the European-level debate, partly from the perspective of European expectations and standards that are employed in evaluation and accession processes. -

This document was developed by the companies and organizations listed in the Appendix. Updates to the Guide are open to input from all companies and individuals that wish to contribute. Those interested in suggesting changes or updates to this document can do so at [email protected]. 2 ATSC 3.0 Transition and Implementation Guide EXECUTIVE SUMMARY Television service continues to evolve as content distributors – from traditional cable operators to internet-delivered services – utilize the latest technologies to reach viewers and offer a wide variety of program choices. New receiving devices are easily connected to the internet, which relies on the language of Internet Protocol (IP) to transport content. Now terrestrial broadcasters are preparing both for the adoption of an IP-ready next-generation digital TV (DTV) standard and a realignment of the U.S. TV spectrum. Viewers are already buying high-quality displays that respond to 4K Ultra HDTV signals and High Dynamic Range (HDR) capabilities. Immersive and personalized audio is also emerging, with the ability to enhance the quality and variety of audio. -

Digital Television: an Overview
Order Code RL31260 CRS Report for Congress Received through the CRS Web Digital Television: An Overview Updated June 22, 2005 Lennard G. Kruger Specialist in Science and Technology Resources, Science, and Industry Division Congressional Research Service ˜ The Library of Congress Digital Television: An Overview Summary Digital television (DTV) is a new television service representing the most significant development in television technology since the advent of color television in the 1950s. DTV can provide sharper pictures, a wider screen, CD-quality sound, better color rendition, and other new services currently being developed. The nationwide deployment of digital television is a complex and multifaceted enterprise. A successful deployment requires: the development by content providers of compelling digital programming; the delivery of digital signals to consumers by broadcast television stations, as well as cable and satellite television systems; and the widespread purchase and adoption by consumers of digital television equipment. The Telecommunications Act of 1996 (P.L. 104-104) provided that initial eligibility for any DTV licenses issued by the Federal Communications Commission (FCC) should be limited to existing broadcasters. Because DTV signals cannot be received through the existing analog television broadcasting system, the FCC decided to phase in DTV over a period of years, so that consumers would not have to immediately purchase new digital television sets or converters. Thus, broadcasters were given new spectrum for digital signals, while retaining their existing spectrum for analog transmission so that they can simultaneously transmit analog and digital signals to their broadcasting market areas. Congress and the FCC set a target date of December 31, 2006 for broadcasters to cease broadcasting their analog signals and return their existing analog television spectrum to be auctioned for commercial services (such as broadband) or used for public safety communications.
