Central Digital Television began broadcasting Ten Central, One HD and One Digital as digital satellite channels on 30 June 2010, the same day as the Viewer Access Satellite Television service was partially launched. Southern Cross Central and Imparja Television also commenced broadcasting digital satellite channels on the same day. The launch of the commercial digital channels coincided with the first analog television transmitter switch off in Mildura, Victoria. This was so viewers in the area who lost adequate television coverage were able to utilise VAST as an alternative source.
On 10 December 2010, VAST officially launched and began granting access to viewers in the Remote Central and Eastern Australia licence areas. This brought digital television to satellite viewers in the Northern Territory, Queensland and South Australia for the first time. Digital terrestrial transmissions began in Alice Springs, Northern Territory and Mount Isa, Queensland on 2 May 2011, with other areas launching between 2012 and 2013.
CDT is affiliated to Network Ten, but sources programming from two stations. Ten Central North is based on TVQBrisbane, and airs Ten Eyewitness News Brisbane nightly at 5pm, as well as sports and events live in the Brisbane market. Ten Central South and One is based on ATVMelbourne, including news and sports. Both Ten Central channels also air programming produced by Southern Cross Austereo. Eleven is the same as it is in every region.
Central Digital Television broadcasts free-to-air digital television channels Ten Central, One and Eleven via terrestrial transmissions in many regional cities and towns. The network is licenced to broadcast within the Remote Central and Eastern Australia TV2 and Mt Isa TV1 licence areas, which include Alice Springs, Bourke, Ceduna, Charleville, Coober Pedy, Cooktown, Katherine, Longreach, Mount Isa, Roma and Weipa, as well as others.
