History of the DVB Project
History of the DVB Project (This article was written by David Wood around 2013.) Introduction The DVB Project is an Alliance of about 200 companies, originally of European origin but now worldwide. Its objective is to agree specifications for digital media delivery systems, including broadcasting. It is an open, private sector initiative with an annual membership fee, governed by a Memorandum of Understanding (MoU). Until late 1990, digital television broadcasting to the home was thought to be impractical and costly to implement. During 1991, broadcasters and consumer equipment manufacturers discussed how to form a concerted pan-European platform to develop digital terrestrial TV. Towards the end of that year, broadcasters, consumer electronics manufacturers and regulatory bodies came together to discuss the formation of a group that would oversee the development of digital television in Europe. This so-called European Launching Group (ELG) expanded to include the major European media interest groups, both public and private, the consumer electronics manufacturers, common carriers and regulators. It drafted the MoU establishing the rules by which this new and challenging game of collective action would be played. The concept of the MoU was a departure into unexplored territory and meant that commercial competitors needed to appreciate their common requirements and agendas. Trust and mutual respect had to be established. The MoU was signed by all ELG participants in September 1993, and the Launching Group renamed itself as the Digital Video Broadcasting Project (DVB). Development work in digital television, already underway in Europe, moved into top gear. Around this time a separate group, the Working Group on Digital Television, prepared a study of the prospects and possibilities for digital terrestrial television in Europe. -

Digital Television Systems
This page intentionally left blank Digital Television Systems Digital television is a multibillion-dollar industry with commercial systems now being deployed worldwide. In this concise yet detailed guide, you will learn about the standards that apply to fixed-line and mobile digital television, as well as the underlying principles involved, such as signal analysis, modulation techniques, and source and channel coding. The digital television standards, including the MPEG family, ATSC, DVB, ISDTV, DTMB, and ISDB, are presented toaid understanding ofnew systems in the market and reveal the variations between different systems used throughout the world. Discussions of source and channel coding then provide the essential knowledge needed for designing reliable new systems.Throughout the book the theory is supported by over 200 figures and tables, whilst an extensive glossary defines practical terminology.Additional background features, including Fourier analysis, probability and stochastic processes, tables of Fourier and Hilbert transforms, and radiofrequency tables, are presented in the book’s useful appendices. This is an ideal reference for practitioners in the field of digital television. It will alsoappeal tograduate students and researchers in electrical engineering and computer science, and can be used as a textbook for graduate courses on digital television systems. Marcelo S. Alencar is Chair Professor in the Department of Electrical Engineering, Federal University of Campina Grande, Brazil. With over 29 years of teaching and research experience, he has published eight technical books and more than 200 scientific papers.

The Transition to Digital Television*
DIGITAL TELEVISION 1 The Transition to Digital Television* Jérôme Addaa and Marco Ottavianib University College London; London Business School This paper studies the role of economic policy for the transition from analogue to digital television, with particular attention to the switch off of the analogue terrestrial signal. The analogue signal cannot be credibly switched off until almost all viewers have migrated to digital, due to universality of access to television. But before switch off, only part of the population can be reached with the digital signal. In addition, those who are reached need to spend more to upgrade their reception equipment than after switch off, because the capacity to increase the power of the digital signal will be made available only then. After reviewing the competitive structure and the role of government intervention in television markets, we present the early experience of a number of industrialised countries in the transition to digital television. We then formulate a micro-econometric model of digital television adoption by individual viewers. The model is calibrated to UK data and simulated to predict the impact of government policies on the take up of digital television. Policy makers can affect the speed of take up of digital television by: (i) controlling the quality of the signals and the content of public service broadcasters; (ii) intervening in the market for digital equipment with subsidies; and (iii) publicising the conditions and date of switch off of the analogue signal. We find that if the analogue terrestrial signal is switched off conditionally on aggregate adoption, strategic delays possibly arise and expectations affect the success of the switch off policy. -

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. -
