The TelstraClear IPTV Trial on KAREN has concluded

As of 01 September 2009, the Media Streaming via Multicast is no more.

TelstraClear was very pleased to offer a trial IPTV solution to KAREN members and the National Education Network pilot.

KAREN provided an ideal medium for this technology, delivering multicast streams over a high speed and low latency network. The initial broadcast of free to air TV and a selection of radio broadcasts was designed to test the potential use of this medium for educational use.
