Collectively, these Working Group's provide for the industry-approved introduction of new solutions and services to the D-Book, currently on its seventh iteration, D-Book 7.[5] D-Book 8 is due to be published in late 2014/early 2015,containing support for the forthcoming Freeview Connected platform, a profile for tablet computer DTT receivers and preparations to smooth the potential 700 MHz clearance.[6]

About

The DTG publish and maintain the D-Book, the technical foundation of the United Kingdom's Freeview, Freeview HD, Freesat and YouView television platforms – covering 95% of UK homes with a digital TV.[7] It also actively encourages and supports the development of Sky, Virgin Media, BT TV, TalkTalk, Connect-TV and VuTV.

History

The DTG was formed in 1995 by the BBC, BSkyB, BT Group, Channel 4, ITV (TV network) NTL Incorporated, Pace and Sony to set technical standards for the implementation of digital terrestrial television in the UK.

From these initial eight members, the DTG has grown to include over 120 UK and international members and played a decisive role in the success of the UK television industry.[4]

Current work

The DTG, working with its members, has identified six priority television technologies to pursue and bring to fruition with the maximum benefit, these are:

  • Ultra high definition: creating a revolution in next-generation TV definition, not a resolution, working through the DTG UK UHD Forum.[8]
  • Digital terrestrial television: maintenance of the technical specification (D-Book).[9]
  • Video-to-mobile: improving the efficiency of delivery and the consumer experience of streaming video on portable devices using mobile data.[10]
  • Spectrum: driving full value by managing change/coexistence through supporting the introduction of new services.[11]
  • Connected TV: developing industry-wide ad insertion and home-networking solutions.[12]
  • Accessibility: improving the experience of TV for viewers with accessibility requirements.[13]

Membership

The DTG is a members association with four categories of membership:[14]

  1. Full Member for organisations who are active in the UK market.
  2. New Entrant for new organisations in their first two years of operation.
  3. World Member for organisations who are interested in, but not active, in the UK market.
  4. Affiliate Member for charities, governments and regulators with an interest in the UK market and/or technical aspects of the television industry.

DTG Testing

The DTG owns and operates DTG Testing, an ISO 17025 accredited test laboratory in Central London. DTG Testing ensures digital television products in the United Kingdom conform to the D-Book specification[15] – a requirement of obtaining the Freeview trade mark licence.[16]

  • Training[22]

The D-Book

The DTG publishes and maintains the D-Book. It is currently on its seventh edition (released March 2011[5]) providing the detailed interoperability specification for digital terrestrial television in the United Kingdom with extended Connected TV functionality. D-Book 7 provides the baseline specification that YouView, Sky, Virgin Media and others can build on for trademark requirements to support their services.
