In modern visual communications, transmitted data may be discardedbecause of network congestion. With the constraint on transmissiondelay, the lost data cannot be retransmitted and therefore may causea fatal degradation on the visual quality. In this paper, we discusssome topics of delivering MPEG video over networks for robusttransmission. Not only are relevant techniques introduced, but wealso present an empirical bandwidth allocation strategy. Theessential motivation of the proposed strategy is to eliminate thebust of MPEG video streams and thereby retain the duality of visualservice. The experimental results indicate that the proposed strategycan allocate an effective bandwidth for MPEG video streams. Moreover,the proposed strategy can still maintain the same level of networkutilization that compares to the optimum solution, which is foundbased on an exhaustive search.
