The D-Book

The D-Book is the technical specification for all UK Digital Terrestrial Television (DTT) based platforms including Freeview Play, YouView, EETV, Now TV, Freesat, and several international adaptations such as Freeview New Zealand.

The D-Book defines the DTT platforms in the UK and provides requirements for interoperability in clear, unambiguous language. Based on international standards it is produced collaboratively by industry experts and only includes features where there is a guarantee or shared wish to implement on the platform. Where appropriate it delivers harmonisation with other international bodies, enabling manufacturers and service providers to deliver products to market.

D-Book conformance is a requirement for compliance with the UK market

There are three conformance test suites connected to the D-Book:

D-Book Conformance Test Suites (required for Freeview Play)

Freesat Conformance Test Suites

Freeview NZ Conformance Test Suites

The test suites can be licenced for use in-house via end-user licencing agreements, or full testing can be carried out by DTG Testing to an agreed test plan.
