Digital Radio offers listeners exceptionally high quality sound as well as features such as programme associated data and still images. DAB enables the broadcaster to provide multi-channel services resulting in the more efficient use of spectrum. It has many added features including allowing listeners to select shows from an electronic program guide, rewind and pause programmes and show scrolling information.
Broadcast Australia actively conducted a Digital Radio Broadcasting (DAB) trial in Melbourne prior to the introduction of new DAB services in Australia in 2009. The trial played a pivotal role in the development of knowledge relating to DAB standards and technology.
Broadcast Australia continued to play a key role in the representative organisation WorldDAB and was a member of the Working Party for the extension of the DAB standard to incorporate the advanced audio coding standard, DAB+. The DAB+ system supports up to four times as many services in a digital audio broadcast (DAB) multiplex, while maintaining high-quality sound.
Broadcast Australia provides fully managed DAB+ services to the national broadcasters, operations and maintenance of the joint venture commercial radio networks multiplex licensees, as well as key roles in the ongoing trials in Canberra and in Darwin.
