The growth of Asynchronous Transfer Mode (ATM) technology and the maturity of coding standards have made the large- scale deployment of high-quality audiovisual services possible. In this article, we discuss the principal issues involved in transporting MPEG-2 streams over ATM networks for both constant bit- rate (CBR) and variable bit-rate (VBR) MPEG-2 Transport Streams. We review existing and proposed approaches to deal with these issues and evaluate some of them by simulation to demonstrate the important tradeoffs in the design of networked audiovisual systems.
