The firm has just completed trials in which it successfully transmitted a 50 megabit per second Mpeg ML/MP 4:2:2 digital video and audio signal over its IP fibre network into central London. Studiolink managing director Steve Gunn said both Channel 4 and the BBC were able to access the resulting SDI feed via BT Tower and make successful recordings.
Gunn said: 'We tested the broadcast over the IP system from our TV studios and also from an ordinary office to prove that our system could transmit broadcast TV pictures from anywhere on either site. The IP is carried over ordinary telephone lines hence can be operated from anywhere on the system.'
Studiolink was set up in March to provide high-speed global transfers of video and audio material, plus a broadband intranet and email service for film and TV studios ( Broadcast, 21.2.02). According to Gunn, the success of the trials now paves the way for transmitting whole TV channels over the network).
