QoS-based synchronization of multimedia document streams

In this paper, we discuss various characteristics of multimedia data and the effect of the network on the required quality of service for multimedia data in terms of synchronization. Scheduling transmission of multimedia information for synchronized delivery, over broadband networks with limited resources, and is identified as an NP-hard problem. We introduce two parameters to measure the performance of end-to-end synchronization protocols for networked distributed multimedia applications. We propose various heuristic scheduling algorithms for multimedia synchronization and compare their performance.
