The Viewer Access Satellite Television service, or VAST, is a satellite television platform in Australia, providing digital television and radio services to remote and rural areas, as well as viewers in terrestrial black spots. The service uses the Optus C1 and Optus D3 satellites. It is partly funded by the Australian Government and managed through a joint-venture between Southern Cross Media and Imparja Television. It is an even more restricted free-to-view replacement for Optus Aurora providing channels which have been absent (such as a Network Ten affiliate and digital only secondary and HD network channels) on the remote service until now. The platform uses only H.264 video encoding and 8PSK, which allows for more lower bit rate channels on the limited transponder space that's available. The EPG uses an MHEG-5 guide instead of the usual more compatible DVB EIT.
History On 10 January 2010, the Australian Government announced a new satellite service to deliver digital television and radio channels to Australian viewers who reside in remote and rural areas, or who can't obtain adequate television signal in an existing metropolitan or regional terrestrial broadcast area, commonly referred to as being in a black spot. Initially, the service was only available to viewers in and around Mildura, Victoria, to coincide with Australia's first analog television switch-off. On 15 December 2010, the service was made available to viewers in the existing Remote Central and Eastern Australia and Mt Isa licence areas. In April 2011, the Western VAST service began for Regional and Remote Western Australia viewers. From December 2013, CRN, NIRS, RPH, and the BBC World Service were transitioned to the new satellite platform over a two-month period from the existing Aurora platform and were the final channels to make the transition. From February 2014 was when the last Aurora uplink is ended.
Availability Anyone is entitled to access ABC and SBS channels on the VAST service, after completing a successful application, regardless of location within Australia. Several different groups of people are currently entitled to use the VAST service to receive commercial stations:
Those who live in areas designated as being part of the Remote Central & Eastern Australia licence area. Those who live outside the Remote Central & Eastern Australia licence area and meet any of these conditions: live in an area predicted to have no terrestrial digital coverage have approval to view the existing Optus Aurora service; due to being in a signal black spot those who do not have Optus Aurora approval, in which they may apply for VAST from 6 months before the switchover in their licence area.1 Those who are traveling in the Remote Central & Eastern Australia and the Regional and Remote Western Australia licence areas may apply for a temporary travellers approval. (Allowing 6 months access). Those who live in areas of Western Australia where terrestrial coverage is not predicted to be available after the completion of the digital switchover in that state.
1 – It was previously possible to apply for the Optus Aurora service instead, and then move to VAST before the 6-month period preceding digital switchover in the applicable licence area.
Equipment Viewers accessing the service must use a VAST certified satellite television set-top box and smartcard, and go through an application process. The original set-top box is a model provided by the South African owned vendor Altech UEC, which also offers models with recording functions along with the newer offerings from Korean owned vendor Humax and a basic model "SatKing" from Australian owned vendor Phoenix Technology Group. The units with a recording function inhibit forward cuing and skipping to prevent commercials being bypassed. Unlike the Aurora service, VAST only uses Irdeto version two and three (not version one) for DVB encryption key management with each smart card locked to the serial number of the provided set-top box.
Channels VAST is designed to provide the same number of digital television and radio channels available in metropolitan terrestrial areas. A minimum of 17 digital television channels are currently available to eligible viewers. The service also provides a minimum of 39 digital radio channels and a number of niche channels. The channels are sorted into bouquets based on a number of states and territories in Australia. Each VAST certified set-top box is assigned a bouquet suitable for the geographical location the set-top box is registered to.
