    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.

  • TEN YEARS of INNOVATION DVB Celebrates Tenth Anniversary at IBC
    PRESS RELEASE Contact: Harold Bergin Tel: +44 (0)20 7799 3100 WHD Public Relations E-mail: [email protected] P.O. Box 3035, London SW1P 3BH United Kingdom TEN YEARS OF INNOVATION DVB Celebrates Tenth Anniversary at IBC Amsterdam – 12 September – At this year’s IBC, DVB is celebrating ten years of creating standards that have formed the backbone for cable, satellite and terrestrial digital transmissions around the world. The DVB Project provided the forum for gathering the major television interests into one group to develop a complete set of digital television standards based on a unified approach. Ten years on DVB is globally the most important force in the on-going development of the digital broadcasting world which now boasts over one hundred million digital homes worldwide. Today, there are forty-five DVB created standards/specifications that are published by the European Telecommunications Standards Institute and a further twenty implementation guidelines. The successful work of the DVB Project is demonstrated in the fact that DVB-S, the specification for digital satellite and DVB-C, the specification for digital cable systems, are available and in use on every continent. The standard for digital terrestrial television, DVB-T, goes from strength to strength and is highlighted by the recent overnight switch from analogue to digital in Berlin, the one hundred thousand a month take-up in the United Kingdom, and the rapid deployment of services in other countries around the world. For example, the mobile capabilities of DVB-T are employed in Singapore for the public transport system to provide customer information.

  • Designing Interactive Tv for a Universal Platform
    PRESS RELEASE For Immediate Release Contact: Harold Bergin Tel: +44 (0)20 7799 3100 WHD Public Relations E-mail: [email protected] P.O. Box 3035, London SW1P 3BH United Kingdom DESIGNING INTERACTIVE TV FOR A UNIVERSAL PLATFORM Key Standards Bodies Worldwide Cooperate To Foster iTV. Geneva – 8 December 2003 – The DVB’s objective to create a write once, run anywhere environment for interactive television applications is now closer to realisation. With the earlier announcements from CableLabs and the ITU, followed by the ARIB in Japan and now the ATSC all endorsing the principle of a global standard for interactive television, DVB’s market driven initiative will foster dynamic creative content and the future development of interactive television. The main thrust behind these announcements has been these standards bodies adoption of the DVB-GEM (Globally Executable MHP) specification, which is at the core of MHP. Up until now, the world has been dominated by a multitude of proprietary middleware systems and application developers are anxious to ensure that the advent of open middleware systems does not mean that they simply have yet another platform to target for their applications. DVB, by developing GEM, and the set of measures around it, has ensured that those organisations wishing to adopt MHP for non-DVB environments can now do so. With market analysts predicting that by the end of 2005 there will be over 250 million iTV enabled homes around the world, harmonisation under a single platform is seen as a major breakthrough that will drive the success of iTV. Content that has a universal appeal and can be formatted to a single standard has a far greater degree of mobility and therefore a larger audience potential.

  • NCTA Comments on the ENERGY STAR Version 4.1 STB Specification
    April 13, 2012 Katharine Kaplan EPA Team Lead ENERGY STAR Product Development US Environmental Protection Agency 1200 Pennsylvania Avenue, N.W. Washington, DC 20460 [email protected] Re: ENERGY STAR® Specification for Set-top Boxes Version 4.0 Dear Ms. Kaplan: On behalf of the National Cable & Telecommunications Association (“NCTA”), I am responding to the Environmental Protection Agency’s (“EPA”) March 20, 2012 request for comment on ENERGY STAR® Specification for Set-top Boxes Version 4.0 (“ESv4”). Since the adoption of EPA’s Energy Star Version 3.0 and 4.0 specifications for set-top boxes, the cable industry has launched new initiatives dedicated to improving the energy efficiency of cable-provided consumer set-top boxes on an aggressive timeline. These new initiatives include (1) the creation of CableLabs - Energy Lab (a specific facility within CableLabs1 dedicated to improving energy efficiency); (2) focused projects to increase the efficiency of set-top boxes through development of “light sleep” and “deep sleep” set-top box modes that function with U.S. cable system architectures; and (3) cable operator volume procurement commitments for set-top boxes that meet ENERGY STAR standards to move the 1 Cable Television Laboratories or CableLabs, founded in 1988, is the cable industry’s R&D consortium playing a role similar to that played by BellLabs for the telephone industry. CableLabs has over 40 cable operator members representing over 80 million customers, predominantly in North American (US and Canada), but also internationally in Europe, Asia, and Central America. Among other things, CableLabs developed common specifications for the cable modem enabling the size and price of such modems to plummet in a short time as they were made available at retail outlets across the country which, in turn, spurred the revolution in broadband access the Nation has experienced in recent years.

  • JAPAN in LINE for MHP ARIB Decision on GEM Opens the Way for Global Interactive Television Standard
    PRESS RELEASE Contact: Harold Bergin Tel: +44 (0)20 7799 3100 WHD Public Relations E-mail: [email protected] P.O. Box 3035, London SW1P 3BH United Kingdom JAPAN IN LINE FOR MHP ARIB Decision on GEM Opens the Way for Global Interactive Television Standard. Geneva – 12th September 2003 – The Japanese television standards organisation ARIB’s decision to adopt a new DVB-GEM based ARIB Standard B-23 “Application Execution Engine Platform for Digital Broadcasting” sets the scene for MHP to be recognised as the true world standard for interactive television (iTV) applications, services and content. The move by ARIB will allow MHP based interactive services to run on ISDB (Japan’s digital television system) networks. GEM offers a means of ensuring that MHP applications can be carried over networks other than DVB. In territories where DVB has not been adopted, and therefore where the original MHP standard cannot be fully implemented, application interoperability is assured by combining MHP based GEM with the appropriate specifications with similar functionality from another body to produce a GEM receiver. The next stage in the process is to finalise the next version of DVB’s GEM specification including the elements necessary to ensure interoperability with ARIB- GEM based receivers. While certain issues need to be resolved by DVB and ARIB experts, the result will be a significant boost for iTV developers around the world. Japan's satellite broadcasting market is divided between ISDB-S and DVB-S systems. Interactive applications running on ISDB-S services in Japan are currently based on BML (Broadcast Mark-up Language).
