The DTG has published a new version of the D-Book, the technical standard for digital terrestrial TV in the UK.
It’s followed by Freeview, YouView, Freesat, EE TV, BT TV and TalkTalk TV.
A number of sections covering areas that are no longer required have been removed.
This includes High Definition (HD)/Standard Definition (SD) Logical Channel Number (LCN) switching and Broadcast Record lists, as well as the complete removal of the Standard Definition receiver profiles.
Chapters describing UK-specific Common Interface and Conditional Access requirements are also no longer in the book.
In D-Book 12 there are changes to receiver update mechanisms following the closure of the Engineering Channel. Remote updates via a network connection or a flash drive are still required.
Richard Lindsay-Davies, CEO of the DTG said; “The D-Book uniquely specifies every TV sold in the UK supporting the key principle of universality, namely that Public Service Broadcaster (PSB) programmes should be available to everyone, free at the point of use. The critical tenet will remain at the centre of our work as we embrace the converged media future of UK television.”
D-Book 12 is available free to all DTG Members.
Non-DTG Members can purchase the D-Book for £50,000.
