  • 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.

  • “Authentic” News: Voices, Forms, and Strategies in Presenting Television News
    International Journal of Communication 10(2016), 4239–4257 1932–8036/20160005 Doing “Authentic” News: Voices, Forms, and Strategies in Presenting Television News DEBING FENG1 Jiangxi University of Finance and Economics, China Unlike print news that is static and mainly composed of written text, television news is dynamic and needs to be delivered with diversified presentational modes and forms. Drawing upon Bakhtin’s heteroglossia and Goffman’s production format of talk, this article examined the presentational forms and strategies deployed in BBC News at Ten and CCTV’s News Simulcast. It showed that the employment of different presentational elements and forms in the two programs reflects two contrasting types of news discourse. The discourse of BBC News tends to present different, and even confrontational, voices with diversified presentational forms, such as direct mode of address and “fresh talk,” thus likely to accentuate the authenticity of the news. The other type of discourse (i.e., CCTV News) seems to prefer monologic news presentation and prioritize studio-based, scripted news reading, such as on-camera address or voice- overs, and it thus creates a single authoritative voice that is likely to undermine the truth of the news. Keywords: authenticity, mode of address, presentational elements, voice, television news The discourse of television news has been widely studied within the linguistic world. Early in the 1970s, researchers in the field of critical linguistics (CL; e.g., Fowler, 1991; Fowler, Hodge, Kress, & Trew, 1979; Hodge & Kress, 1993) paid great attention to the ideological meaning of news by drawing upon a kit of linguistic tools such as modality, transitivity, and transformation.
