The Telecommunications Authority (TA) has published the two-tier technical specification for the digital terrestrial television (DTT) receivers so that consumer electronics manufacturers are able to produce and supply compliant DTT receivers, including set-top boxes and integrated TV sets, for the Hong Kong market.

The two-tier specification, namely the basic-tier and the higher-tier specifications, is to cater for the different DTT deployment plans of the two free-to-air broadcasters and the versatile needs of consumers. The basic-tier receivers primarily aim at receiving the four existing local free-to-air television programme channels transmitted in digital format. The higher-tier receivers will allow consumers to enjoy all DTT programme channels including high-definition television (HDTV) programme channels.
