Conformance explained

The ‘digital tick’, was developed as a certification mark to help consumers through switchover in the United Kingdom.

The logo was designed to identify digital TV products (such as integrated digital TV sets, digital boxes and digital television recorders/DTRs) and digital TV services (such as Freesat, Freeview, Sky and Virgin Media) that will work through digital switchover.

The digital switchover process completed in October 2012, therefore products released after this date do not bear the digital tick logo.

Freeview is the UK’s free-to-air digital terrestrial television (DTT) service, offering up to 50 TV channels and 24 digital radio stations with no subscription or contract. Freeview is now in over 70% of UK homes. Since the service launched in 2002, the total sales of DTT devices in the UK has reached over 60 million units. Around 98.5% of the UK can receive Freeview.

Freeview+ is Freeview’s subscription and contract free digital recorder service. The receiver allows viewers to record a series, record directly from a seven-day TV guide with one button, pause live TV and store hundreds of hours of programmes.

The BBC, ITV, Channel 4 and S4C in Wales broadcast high definition channels on Freeview HD.

Freeview HD is currently available to 98.5% of the UK population. In order to receive Freeview HD, consumers will need to purchase new Freeview HD digital boxes or Freeview+ HD recorders or integrated Freeview HD TVs.

The Freeview and Freeview HD logos are given to products that meet D-Book standard. The D-Book is the technical specification for digital terrestrial television in the UK.

Freesat is the UK's subscription-free satellite TV service offering more than 140 TV, radio and interactive services.

DTG Testing developed and implemented the test and conformance regime for Freesat, building on the experience the Test Centre gained on the Freeview DTT platform. DTG Testing works with manufacturers to ensure their Freesat equipment meets the Freesat and Freesat+ specification. The test centre holds a contract to provide product testing for Freesat and all products have to pass the DTG’s tests before they can use the Freesat, Freesat+ and Freesat HD logos.

DTG Testing has created a set of industry-approved test suites that ensure products meet the performance required to meet the criteria for the Freeview, Freeview+, Freeview HD and Freesat logos.

Manufacturers use reports generated by product conformance testing at the DTG’s Test Centre as evidence to achieve the Freeview, Freeview +, Freeview HD and Freesat logos.

at800 is the brand name of Digital Mobile Spectrum Limited (DMSL), the not-for-profit organization that has been formed by, and represents, mobile network operators with spectrum at 800 MHz.

at800 has commissioned DTG Testing to verify that the 4G filters it supplies to UK homes to mitigate any interference meet its specifications.

Filters that pass DTG Testing's rigorous testing will be given the rights to use the at800 logo.
