ACST[3] The channel started transmitting television programs on 28 April 2008 as part of a testing period ahead of the official launch.

Since April 2008, the station also carries 10 News First Melbourne bulletins from ATV-10, instead of the Brisbane and Sydney feeds, as well as a small amount of 10 Sport programming.

The station has carried a sole 10 affiliate, on relay from Melbourne instead of Brisbane or Sydney, despite time zone differences between Northern Territory and Victoria.

DTD rebroadcasts a direct feed of Brisbane's TVQ-10 instead of Sydney's TEN-10 or Melbourne's ATV-10 because of time zone differences between New South Wales/Victoria and the Northern Territory, especially during the summer months.

On 22 April 2010,[4] DTD began broadcasting "One", a sports-only high-definition channel, owned by Network Ten.
