Issues in Video Transmission Over Broadband ATM Networks

Abstract

Broadband ATM networks at multi-megabit data rates will provide the necessary bandwidth for high-quality interactive video applications. Performance requirements for high quality video services are introduced. Results of statistical simulations of broadband networks transmitting video signals are shown to demonstrate that VBR coding provides gains in multiplexed channel utilization and in BISDN link capacity. Issues relating to protocol design for ATM networks, particularly congestion control and error control are introduced. Finally various techniques for handling cell loss are compared.
