Coding/Compression Requirements from the Network Protocol's Viewpoint

Several major efforts are under way in the Internet community to bring real-time mu communications into reality. Most of the efforts are targeted to solve network-related issues and leave the coding/compression problems to be answered by industry after market value becomes obvious. However, at this point, most of the codec vendors ar focusing on the constant-bit-rate network, which is the current telephone network infrastructure. In this paper, we will demonstrate the importance of developing vari bit-rate compression algorithms and standards. This effort is not only for users in t Internet community, but also for users in the next generation of the telecommunicati network (broadband ISDN), which uses ATM (Asynchronous Transfer Mode) technol Due to a strong dependency between coding/compression and networking for variab rate networks, we will attempt to specify the requirements for the compression algor designs and experiments from the networking point of view.
