Digital Terrestrial Television

DTG members maintain and support the technical specifications of the DTT platform, detailed in our definitive D-Book, through numerous expert working groups. While ensuring technical integrity across the D-Book, these groups also ensure interoperability and define the profiles that form the basis of the Freeview and YouView trademark licenses.

Looking forward, DTG members are committed to developing a roadmap to cover the clearance of 700MHz, while resolving any uncertainties. The groups will also establish the potential for efficiency improvements in migrating the market to DVB-T2, and to explore the future impact of HEVC.
