Digital television — Requirements for receivers for VHF/UHF DVB-T television broadcasts including ancillary services

Specifies the requirements for equipment to be used in Australia for the reception of free-to-air (FTA) terrestrial VHF/UHF DVB-T broadcast television and allow access to all program services offered. In addition, this Standard also covers a number of optional features that manufacturers may provide. These optional features include PVR capabilities and other extended functionality such as HbbTV.
