What we do

Our mission

Through world-class collaboration, bring audio-visual innovation to life.

What we've accomplished

The D-Book

We publish and maintain the technical specifications for Freeview, the most popular platform in the UK, known as the D-Book.

Digital Switchover

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)

High Definition

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 ISO17025 accredited digital TV test centre which provides benchmark test and conformance services for the Freeview and Freesat services and international platforms.

Future programmes

We're bringing industry together to understand new technologies and create new opportunities, in six main worksteams
