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. He is Founder and President of the Institute for Advanced Studies in Communications (Iecom) and has consulted for several companies and R&D agencies. -
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. -

Meintel, Sgrignoli & Wallace CPB A Report To The Corporation for Public Broadcasting Regarding ATSC 3 Digital Television Implementation for Public Television Dennis Wallace MEINTEL, SGRIGNOLI, & WALLACE, LLC 1282 Smallwood Drive, Suite 372 Waldorf, MD 20603 (202) 251-7589 January 31, 2018 ATSC 3 Implementation 1 of 27 Meintel, Sgrignoli & Wallace CPB Executive Summary The firm of Meintel, Sgrignoli, and Wallace, LLC (MSW) is pleased to provide the following report to the Corporation for Public Broadcasting (CPB) regarding the adoption and implementation of the ATSC 3 television standard. Specifically, MSW was tasked with studying the potential impacts and opportunities for public television (PTV) stations as the new ATSC 3 television standard is implemented by broadcasters. The purpose of this report is to highlight some of the technological advances and focus on some of the potential opportunities and business considerations, as well as to generally outline the transition plan for TV broadcasters to transition to ATSC 3 in their respective markets. PTV broadcasters are particularly interested in ATSC 3 as an opportunity to provide new and innovative services to their audiences and communities, as well as to explore new revenue models that may be attractive in today’s environment. Additionally, PTV broadcasters, with their specific missions, are particularly well suited to benefit from the advances available in ATSC 3. However, with all the excitement of new services, new highly-efficient technologies, and new potential business models, PTV stations must also approach ATSC 3 with feasible business plans while minimizing financial risk to their organizations. As ATSC 3 is deployed and implemented across the United States, stations must also safeguard their existing operations, organizational missions, and financial resources in order to take full advantage of ATSC 3 once it is fully deployed and viable. -

Experience DTV Using LCD TV
Experiencing DTV on the LCD TV What is DTV? DTV stands for Digital Television, the latest standard and the future of television broadcasting. Unlike analog TV, DTV is broadcast digitally to transmit an audio and video signal for movie-like picture quality and surround sound. HDTV, your ticket to movie theater experiences on your home TV set, is a Digital TV (DTV) format. There are many benefits to DTV, as we will explain below. In addition, on February 1st, 2006, Congress passed a law mandating that all analog TV broadcasts must cease on February 17, 2009. At present, many television stations have begun broadcasting programs digitally. Benefits of Digital Television Improved image and sound quality Digital signals are not prone to interference during transmission, resulting in high fidelity signals all the way to the TV set for immaculate colors, incredible image sharpness and great sound. With DTV we can say goodbye to “ghosting” and “snow” on the TV screen and noise from the speakers. In addition, DTV supports high quality picture formats such as HDTV, meaning you will be able to enjoy movie-like programming right in the comfort of your own living room! Interactive programming With analog TV, we could do very little else with our TV programs other than change the channel. DTV provides us with an interactive viewing experience, a good example of which is the ability to order whichever program we please directly through the TV. That was impossible in the analog TV age. DTV Picture Quality Levels There is more than one DTV picture quality level or format. -
