An Experimental Evaluation of Video Coding Algorithms for ATM-based Networks

Recent advances in network technology have increased the bandwidth available on high speed networks, and enabled the development of new network applications such as real-time video teleconferencing and medical imaging. In networks such as Broadband-ISDN, the primary goal is to integrate services such as video with existing information services, such as voice and data. Coding techniques for packet video transmission are necessary to eeectively develop and integrate these applications. In this paper, we present an experimental evaluation of several existing coding methods designed for packetized video transmission in an ATM-based network environment such as B-ISDN. Four evaluation criteria are established: compression ratio, picture quality, processing requirements and robustness. Four coding algorithms are then quantitatively evaluated with respect to these criteria, using experimental measurement and simulation.
