Known as the D-Book, the reference guide has now reached its 12th edition. How a device conforms to the D-Book relates to whether or not the manufacturers can say their device works with Freeview Play, YouView or any service that links up with the UK digital terrestrial TV signal, with aspects of the D-Book also covering digital satellite television via Freesat.
The latest annual edition bins requirements relating to High Definition/Standard Definition Logical Channel Number (LCN) switching and Broadcast Record lists, as well as the complete removal of the Standard Definition receiver profiles - as no new devices bearing the Freeview logo are allowed to be SD only.
And following the end of over-the-air software downloads for devices in favour of online updates, the new specs require that you can still update your device remotely, for example via a network connection or locally from a flash drive (or similar).
Chapters describing UK-specific Common Interface and Conditional Access requirements have also been removed because of the increased availability of SVoD services. The now defunct Top Up TV was the last provider to make use of these requirements for its pay TV service.
The changes affect all new devices that are coming on to the market who want to carry an official platform operator logo in their marketing and packaging.
Richard Lindsay-Davies, CEO of the DTG commented on the release of D-Book 12:
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.
