The DTG has released D-Book 12.7 – the latest update to the technical specification for all digital terrestrial television products and services in the UK market.
The D-Book was developed in partnership with industry and is based on International Standards. It ensures interoperability from the broadcaster to the viewer and allows service providers and manufacturers to deliver high-quality products and content to the market with confidence.
The DTG working groups create the D-Book each year to support the consumer electronics industry by ensuring device interoperability through the entire product lifecycle. This critical set of technical specifications is the foundation for Freeview Play, Freesat TV, BT TV Now, TalkTalk TV, and YouView.
D-Book 12.7 supports the current DTT platform, updated following the closure of the UK’s only Single Frequency Network, COM7, on channel 55 and further revising the receiver profiles in Chapter 22 to reflect the HD HbbTV baseline for all UK receivers.
The D-Book is constantly evolving with the market to support rapid development of products and services in highly successful UK markets. It also removes requirements that are not needed. Harmonization with HbbTV/DVB is a priority to ensure international and European harmonisation.
Simon Fell, Chairman, DTG, said, “We’re delighted to continue delivering the only technical standard universally deployed in UK televisions. The D-Book represents a great example industry uniting and working together in order to provide viewers with a reliable and resilient experience. It is crucial in a fragmented marketplace like today. Digital television is essential for education, news, and companionship in a country like the UK, which is facing economic challenges and tighter home finances. It is critical that, as an industry, we protect it.”
