  • 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.

  • Development of a Digital Terrestrial Front End
    DEVELOPMENT OF A DIGITAL TERRESTRIAL FRONT END J D Mitchell (BBC) and P Sadot (LSI Logic, France) ABSTRACT BBC Research and Development and LSI Logic are jointly developing a front end for digital terrestrial television transmitted according to the DVB-T specification. The front end consists of two separate components. First, an analogue down-converter that converts the input signal from UHF to a low IF. Second, an integrated circuit that accepts the analogue signal from the down-converter and performs the required DSP operations, which include synchronisation and demodulation, to form a stream of soft decisions suitable for presentation to an FEC decoder. The development process began by agreeing a set of requirements to which the two components must conform. This paper begins by outlining these requirements. During the development of the components, many issues have been considered and resolved. A selection of the key issues and the decisions that were reached is given and, finally, a discussion of the architecture that results from these decisions is presented. INTRODUCTION BBC Research and Development and LSI Logic are working together on the development of a digital terrestrial front end which is capable of decoding transmissions compliant with the European DVB-T specification (1). This development unites the BBC's system expertise in COFDM, see Nokes et al. (2), Stott (3) and (4), and LSI Logic's long-established chip design capability. As part of the front end development, LSI Logic and the BBC are working together on two distinct, but related, development projects: a single CMOS chip implementing a complete OFDM demodulator, and a new terrestrial down-converter designed for use with the digital chip.

  • Digital Television: Has the Revolution Stalled?
    iBRIEF / Media & Communications Cite as 2001 Duke L. & Tech. Rev. 0014 3/26/2001 April 26, 2001 DIGITAL TELEVISION: HAS THE REVOLUTION STALLED? When digital television technology first hit the scene it garnered great excitement, with its promise of movie theater picture and sound on a fraction of the bandwidth of analog. A plan was implemented to transition from the current analog broadcasting system to a digital system effective December 23, 2006. As we reach the half point of this plan, the furor begins to die as the realities of the difficult change sink in. The History of Digital Television ¶1 The technological possibilities of digital television are immense.1 It could provide the broadcast of theater quality sound and picture via cable, antenna or satellite; multicasting which enables the transmission of multiple programs within one digital signal; and signals for data communications that could potentially bring to the TV the capabilities of web pages and interactive compact discs.2 ¶2 The motivation behind the development of digital television technologies can be traced back to the history of analog broadcasting. As television became a viable medium in the United States at the start of the Second World War, the establishment of technical standards in transmission and reception equipment was of vital importance. In 1940, the National Television Systems Committee (NTSC) met to determine guidelines for the transmission and reception of television signals. With the US leading the charge into early broadcasting in the late 1940s, the technology available at the time became entrenched and remains a part of our lives today, with the familiar 525-line low-resolution screens that bring us the evening news.

  • Digital Radio in Europe
    CORE Metadata, citation and similar papers at core.ac.uk Provided by UCLouvain: Open Journal Repository (Université catholique de Louvain) A GREAT FUTURE ? DIGITAL RADIO IN EUROPE Hans J. Kleinsteuber1 This article is about the diffi cult path towards digital radio in Europe. In technical terms, digitalisation refers to the transformation of commu- nication technologies from an analogue to a binary logic. Digital may be seen as a synonym for « sampled, quantifi ed, and presented in binary characters »; digital broadcasting refers to the transmission of digitised audio, video, and auxiliary information as data signals. (Reimers 2005 : 1) One might say that the logic of the computer, which always worked digitally, is gradually taking over all aspects of the production, distri- bution, consumption, and storing of broadcast messages. What sounds like a purely technical process has strong effects on all aspects of the media, including politics and economics, the production process itself, as well as programme content. One aspect of digitalisation is that it allows for convergence, meaning the fusion of the traditionally separate functions of radio and 1 Professor, University of Hamburg Recherches en communication, n° 26 (2006). 136 HANS J. KLEINSTEUBER the Internet – of mono-directional mass media and interactive individual communication. According to this understanding, technical conver- gence leads to content convergence. As such, convergence does not just describe a technological possibility ; it is seen much more as a model that guides the thinking of engineers, business managers, and political decision-makers about the future of the media. Because of this scenario, it is not only important to analyse what is going to happen, but it is also of central importance to look at the actors behind the process of digita- lisation regarding their interests, their strategies, and their errors.

  • Analysis of the Single Frequency Network Gain in Digital Audio Broadcasting Networks †
    sensors Article Analysis of the Single Frequency Network Gain in Digital Audio Broadcasting Networks † Kamil Staniec Telecommunications and Teleinformatics Department, Wrocław University of Science and Technology, 50-370 Wrocław, Poland; [email protected] † This paper is an extended version of the published conference paper “Staniec, K. SFN gain analysis in digital audio broadcasting networks. In Proceedings of the Microwave and Radar Week (MRW’20), MIKON 2020, Warsaw, Poland, 5–7 October 2020”. Abstract: The single frequency network (SFN) is a popular solution in modern digital audio and television system networks for extending effective coverage, compared to its traditional single- transmitter counterpart. As benefits of this configuration appear to be obvious, this paper focuses on the exact analysis of so-called SFN gain—a quantitative effect of advantage in terms of the received signal strength. The investigations cover a statistical analysis of SFN gain values, obtained by means of computer simulations, with respect to the factors influencing the coverage, i.e., the protection level, the reception mode (fixed, portable, mobile), and the receiver location (outdoor, indoor). The analyses conclude with an observation that the most noteworthy contribution of the SFN gain is observed on the far edges of the networks, and the least one close to the transmitters. It is also observed that the highest values of the SFN gain can be expected in the fixed mode, while the protection level has the lowest impact. Keywords: DAB+; MFN; SFN gain; coverage; protection level; portable; mobile 1. Introduction Citation: Staniec, K.
