The D-Book is updated annually and underpins the technology used by Freeview, YouView, Freesat, EE TV, BT TV and TalkTalk TV.
Richard Lindsay-Davies, CEO of the DTG said: “The pace of change and complexity for our industry increases every year, with PSB prominence and new technologies being discussed in Parliament. It is now more important than ever that industry collaborates to sustain the delivery of cutting technology with the levels of performance, quality, resilience and universality they expect from UK television. Bridging the old with the new and delivering a world-leading television experience for consumers wherever they are, on whatever device”
D-Book 11 includes an update to the RF test process to account for LTE co-existence performance in the 700MHz band instead of the 800MHz band. This comes ahead of the arrival of 5G mobile services.
There are also updates to Alignment with HbbTV 2.0.2 and DVB-DASH and the removal of standard definition profiles following the withdrawal of the Freeview logo in January 2017.
