Tiernan MPEG-2 4:2:2 Codecs Enable Teleglobe to Launch First Contribution Quality Video Transmission Over ATM Networks SAN DIEGO, Feb. 13 /PRNewswire/ -- Broadcast history was made in November 1997, when Teleglobe Millennium(SM) service enabled the Japan Broadcasting Corporation (NHK) to transmit contribution quality video over an Asynchronous Transfer Mode (ATM) network. High-performance Tiernan MPEG-2 equipment played a key role in the milestone event, with Tiernan TE6 4:2:2 Studio Profile Encoders and TDR600 Integrated Receiver Decoders performing the critical digital compression elements. Teleglobe's Millennium digital television service is a technological breakthrough that sends video formatted in the MPEG-2 4:2:2 standard over a bandwidth-efficient ATM backbone. The new service enables broadcasters to transport multiple, high-quality channels on the same amount of bandwidth currently required by a single channel in analog mode. Available now, Millennium offers unprecedented quality, superior network security and higher clarity than satellite broadcast transmission -- all at a significant cost savings over currently available analog technology. Millennium's ATM transport provides nearly unlimited bandwidth and channelization options compared to existing analog routes. Unlike standard broadcast transmissions that can be intercepted from satellite transmission for unauthorized use, Millennium sends digitized pictures in ATM cells over terrestrial and undersea facilities. "Teleglobe's Millennium service and Tiernan digital compression technology are setting the new standard for broadcast transmission," said Paolo Guidi, President and CEO for Teleglobe Global Telecom Services. "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. Millennium also gives broadcasters the ability to set their own quality levels, rather than be limited to those mandated by carriers." NHK used Teleglobe's Millennium service to broadcast the Asia Pacific Economic Conference (APEC) live at an unprecedented 15 Mbps 4:2:2 contribution quality, from Vancouver via their New York bureau to their full-time network, for reception in Tokyo. Major broadcast customers will link with Teleglobe's network via the Tiernan digital compression systems located at each of Teleglobe's Millennium International Television Access Centers (ITACs). Teleglobe's New York ITAC is located at Waterfront Communications, the dominant video switching hub in New York City. The company's London ITAC is located at Tele-Cine, which provides video production and transmission facilities that connect to the BT tower in London. Millennium ITACs are also located in Montreal and Vancouver. Tiernan digital codecs are also scheduled for installation at Teleglobe's planned center in Los Angeles, which will provide a link for Hollywood to Teleglobe's Millennium service. Additional Tiernan digital compression systems will be installed at Teleglobe's planned sites in Paris, Frankfurt, Miami and Washington D.C. Teleglobe provides a full range of international broadcast transmission services on a full-time, events-services and occasional-use basis. Teleglobe is a leading international carrier for broadcasting organizations around the globe, including all four major U.S. broadcast networks, cable television and direct-to-home networks, and others in the United Kingdom, Canada, France, Australia and New Zealand.
