✦ Synopsis

In modern visual communications, transmitted data may be discarded because of network congestion. With the constraint on transmission delay, the lost data cannot be retransmitted and therefore may cause a fatal degradation on the visual quality. In this paper, we discuss some topics of delivering MPEG video over networks for robust transmission. Not only are relevant techniques introduced, but we also present an empirical bandwidth allocation strategy. The essential motivation of the proposed strategy is to eliminate the burst of MPEG video streams and thereby retain the quality of visual service. The experimental results indicate that the proposed strategy can allocate an effective bandwidth for MPEG video streams. Moreover, the proposed strategy can still maintain the same level of network utilization that compares to the optimum solution, which is found based on an exhaustive search.
