Distributed, networked multimedia information systems will be a critical component of technology-based information infra-structures in the future. In this paper, we present an infrastructure for supporting multimedia applications. We discuss various characteristics of multimedia data and the effect of the network on required quality of presentation for multimedia data. We present a suite of synchronization protocols to support quality of presentation. The crux of these protocols is the

We introduce two parameters which can be used to measure the performance of end-to-end synchronization protocols in a network supporting distributed multimedia applications. We propose and implement several heuristic scheduling algorithms, and compare their performance. We deduce the appropriateness of these algorithms in different types of distributed multimedia environments. of pre-orchestrated multimedia information (homogeneous channels case)," in Proc.
