Now available is the Viewer Access Satellite Television service otherwise known as VAST. To access the VAST satellite this is the only decoder (set-top-box) available in the Australian Market.

The DSD 4121 RV is a MPEG 2/4 High Definition digital set top box designed specifically to meet the requirements of the Optus Aurora Digital platform and associated VAST certification process.

The DSD 4121 RV utilizes mature tried and tested technology that allows connectivity to both flat panel and legacy CRT TV’s. The product has been future proofed through the incorporation of an Ethernet port for connection to the internet and USB port that can convert the unit as a PVR unit and/or for media playback.

The DSD 4121 has been designed with an external 12 Volt D.C power supply which provides portability allowing a traveler to connect this decoder to a well regulated 12 Volt D.C supply.

What if I already have Austar at my home?

For those of you who already have a satellite dish on your roof and have Austar, connection of the new VAST decoder is quite simple.  All that needs to be changed is the LNB (device on the end of the dish) and an additional coaxial cable to follow the Austar cable down to connect to the new VAST decoder.  The VAST service is on the same satellite so there’s no need to re-align the dish.  Simply replace the old LNB with a new TWIN OUTPUT LNB.  We use the pay TV approved SHARP Twin Output 10.700GHz LNB. See diagram example below:


If you have MyStar, you’ll already have 2 satellite cables coming in to the MyStar decoder.  Simply disconnect the cables at the back of the decoder, connect them to our Spaun Multiswitch, then connect three short cables from the multiswitch – two cables to the MyStar decoder and one to the VAST decoder.  Simple.  We recommend the Spaun 2 in/8 out Multiswitch.  If you need more information, contact us on the email or phone details below.

What if I’m a traveller?

Travellers are well catered for and can access the new VAST service regardless of where they live.  Registrations can be completed at and scroll down the page to find the travellers form.  Access is granted by way of a temporary reception certificate which lasts 6 months.  The certificate can be renewed an infinite amount of times and there are no costs associated with registrations.
