Abstract :
An overview of the broadband integrated services digital network (BISDN) is given. A codec that compresses high-definition television to fit within the roughly 135-Mb/s capacity of a synchronous optical network synchronous transport signal level 3c (SONET STS-3c) signal carrying BISDN asynchronous transfer mode (ATM) cells, thus requiring compression of roughly only 6:1, is described. The order and format of the transmitted HDTV data is considered. ATM adaption and user layer information are discussed. Error control in the user layer is addressed.<>
