  • 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.

  • R-Rec-Bt.1722-1-200712-S!!
    Rec. ITU-R BT.1722-1 1 RECOMMENDATION ITU-R BT.1722-1 Harmonization of the instruction set for the execution engine for interactive TV applications (Question ITU-R 13/6) (2005-2007) Scope This Recommendation is intended to harmonize the application environment for interactive TV applications. The potential for commonality in the executable application environment is based on the analysis of the common core identified in the work leading to this Recommendation. Such commonality would benefit content providers through knowledge of commonly adopted executable functionality and economies of scale. The ITU Radiocommunication Assembly, considering a) the need to avoid proliferation of protocols for interactive multimedia services; b) that digital broadcasting services (satellite, terrestrial and cable) are becoming widely available and offer multimedia applications; c) that multimedia applications comprising video, audio, still-picture, text, graphics, etc. associated with interactive features have been developed; d) that multimedia applications planned or deployed in some Regions are using the executable application environment; e) that common instruction sets are desirable for production and international exchange of multimedia content; f) that continuous work and review of Application Programming Interfaces (APIs) is being carried out in the ITU-R and ITU-T Sectors; g) that ITU-T Recommendation J.200 defines the high-level architecture for a harmonized set of interactive instruction sets and APIs and identifies the structure of application environment comprising the executable application environment and the declarative application environment for digital television services; h) that ITU-T Recommendation J.202 defines the executable application environment within ITU-T Recommendation J.200 and is the corresponding Recommendation to Recommendation ITU-R BT.1722, recommends 1 that the harmonized instruction set for the execution engines specified in Annex 1 should be used for interactive TV applications in the executable application environment.

This document is paginated for recto-verso printing EBU R 106r2-2008 Statement on the use of DVB-MHP EBU Recommendation on Interactive Multimedia for Digital Broadcasting Geneva, November 2008 Considering: a) Earlier in 2008, the EBU withdrew its Recommendation for the use of MHP in new digital broadcasting services because of uncertainties about licence fees (see overleaf). b) Recently the licence holder Via Licensing announced that its licences for the MHP system will be free of licence charges for free-to-air broadcasters. The EBU Recommends; MHP is considered an appropriate system for interactive television services for new digital broadcasting services by EBU Members. 3 Statement on the use of DVB-MHP EBU R 106r2-2008 4 EBU R 106r2-2008 Statement on the use of DVB-MHP EBU Statement on MHP (Multimedia Home Platform) Geneva, March 2008 MHP At the end of the 1990s, the DVB Project developed, in open discussion, an API termed MHP (Multimedia Home Platform). MHP development was supported by the EBU, and was seen as a 'future proof' API that would evolve over time in different versions. A major element of MHP is the use of the JAVA programming language, developed by Sun Microsystems. In 2001, the EBU issued R106, in which it recommended that MHP should be the API of choice for new digital broadcast services by EBU members, accepting that those who had already started using alternative APIs might not be able to change them.

Chapter 1 Introduction From a developer’s perspective, the APIs for desktop PCs and enterprise systems have been a daunting combination of complexity and confusion. Over the last 10 years, Java™ technology has helped simplify and tame this world for the benefit of everyone. Developers have benefited by seeing their skills become applicable to more systems. Users have benefited from consistent interfaces across different platforms. And systems vendors have benefited by reducing and focusing their R&D investments while attracting more developers. For desktop and enterprise systems, “Write Once, Run Anywhere”™ has been a success. But if the complexities of the desktop and enterprise world seem, well, complex, then the connected device world is even scarier.
