The Digital TV Group (DTG)  is the industry association for Digital Television in the United Kingdom : The Group was formed in 1995 to set technical standards for the implementation of digital terrestrial television in the UK (known as the D-book) and now encompasses all digital TV platforms and convergence issues. The DTG’s members are companies and organisations involved in digital television and associated technologies.
The Group published the sixth edition of the D-book in March 2009. D-Book 6 includes the detailed specification for high definition television services on the UK Freeview platform.
In March 2011 the Group published D-Book 7: the detailed interoperability specification for digital terrestrial television 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.
Following the publication of D-Book 7, the DTG is now bringing industry together to understand new technologies and create new opportunities, in six main worksteams:
Ultra HD, via the DTG UK UHD Forum DTT, maintaining the technical specifications (D-Book) Mobile, improving delivery and interoperability of video to mobile devices Spectrum, driving full value from spectrum while ensuring coexistence Connected TV, leading the search for an industry-wide solution for Ad Insertion and improving Home Networking Accessibility, improving the TV experience for accessibility users
The DTG also operates a ISO17025 UKAS accredited test centre (DTG Testing) which ensures manufacturer’s products conformance to D-Book specification - allowing them to use the Freeview, Freeview Plus and Digital Tick logos. The centre also offers access to the UK’s over-air download channel.
