Teleglobe [TGO] is using asynchronous transfer mode (ATM) technology to deliver its new Millennium video broadcast service. The carrier announced Jan. 26 that it can transmit video over an ATM backbone for commercial broadcasters from sites in New York, London, Montreal, and Vancouver.
Teleglobe intends to build additional Millennium International Television Access Centers in Los Angeles, Paris, Frankfurt, Miami, and Washington, D.C. The company added that it is using MPEG-2 4:2:2 encoding, which allows broadcasters to transport multiple, high-quality channels over the same amount of bandwidth needed to send a single analog channel.
"Offering MPEG-2 4:2:2 video over ATM not only raises the technology bar, it also enables us to offer highest quality, lower cost transmission, with the rapid turnaround demanded by the fast-paced news, entertainment, and sports broadcast environment," said Paolo Guidi, president and CEO for Teleglobe Global Telecom Services. "Millennium also gives broadcasters the ability to set their own quality levels rather than be limited to those mandated by carriers."
Teleglobe said it will offer the service for occasional as well as full time use. (John Murray, Teleglobe International, 703/821-4857) |
