Bits and Bucks

摘要

HDTV means big pictures for viewers and big demand for encoders. More important, producing high-quality HDTV at lower bit rates leaves bandwidth available for networks to dabble in multicasting, data services, and other new forms of digitally delivered content. But encoder demand isn't just about HD. New standard-definition encoders based on advanced compression schemes MPEG-4 and Windows Media 9 will also hit the market at NAB. Although initial demand for these compression schemes has been from telephone companies and cable providers, broadcasters will use them for such applications as electronic newsgath-ering [ENG) or sharing content between stations.
