video streaming• VLC, Windows media & Real player all support IP
multicast• Multicast is particularly useful for high bandwidth
streams which would saturate a link using unicast• HEAnet planning to provide future streaming events &
terrestrial streaming via both multicast and unicast• BBC streams currently available via multicast
