The Digital TV Group (DTG) is the industry association for Digital Television in the United Kingdom : The Group was formed in 1995 to set technical standards for the implementation of digital terrestrial television in the UK (known as the D-book) and now encompasses all digital TV platforms and convergence issues. The DTG’s members are companies and organisations involved in digital television.
The Group operates a test centre (DTG Testing) which ensures manufacturer’s products conformance to D-Book specification - allowing them to use the Freeview, Freeview Plus and Digital Tick logos. The centre also offers access to the UK’s over-air download channel.
The Group published the sixth edition of the D-book in March 2009. D-Book 6 includes the detailed specification for high definition television services on the UK Freeview platform.
In March 2011 the Group published D-Book 7: the detailed interoperability specification for digital terrestrial television with extended Connected TV functionality. D-Book 7 provides the baseline specification that YouView, Sky, Virgin Media and others can build on for trademark requirements to support their services.
Following the publication of D-Book 7, the DTG is now focused on developing the test and conformance regime for UK Connected TV products and services.
The Group is also committed to profiling the UK standard for 3DTV products and services once there is a clear commercial requirement.
Famous quotes containing the word group:
“It’s important to remember that feminism is no longer a group of organizations or leaders. It’s the expectations that parents have for their daughters, and their sons, too. It’s the way we talk about and treat one another. It’s who makes the money and who makes the compromises and who makes the dinner. It’s a state of mind. It’s the way we live now.”
—Anna Quindlen (20th century)
