What we do
Through world-class collaboration, bring audio-visual innovation to life.
The DTG is the unique self-funding UK collaboration centre for innovation in digital media technology, set up in 1995 with the purpose of looking after the digital TV marketplace. It underpins the free-to-air platforms Freeview, Freesat and YouView, and supports the development of pay-TV and other platforms.
It has been central to the distribution of TV in the UK for two decades and is currently embracing the convergence of content and networks to focus on the efficient delivery of video to all screens in all formats.
The DTG is currently supporting the next generation of video delivery technologies through its work in the delivery of video to mobile devices, spectrum coexistence management, home networking, connected TV, accessibility, and UHD.
Who we are
What we've accomplished
We publish and maintain the technical specifications for Freeview, the most popular platform in the UK, known as the D-Book.
The DTG was instrumental in the UK's move to digital TV, with the D-Book specifications and test regimes underpinning the switchover certification mark (the digital tick)
The D-Book 6 represented a landmark in UK broadcasting, providing the specification for the launch of HD services on Freeview, powered by the DVB-T2 modulation standard.
Interoperability and co-existence
We run DTG Testing, the UKAS ISO/IEC 17025:2005 accredited digital TV test centre which provides benchmark test and conformance services for the Freeview and Freesat services and international platforms.
