Based on the analysis and comparison of several typical multimedia synchronization models, this paper presents a new model: Synchronization Time Petri Nets- STPN not only allows the temporal behavior of both intra-media and inter-media to be described fully, accurately, and formally but also solves the problem that time stream Petri net has dead tokens. In particular, STPN introduces inhibitor arcs to handle the problem of synchronization failure because of fire interruption caused by random delay, blocking, or lost packets. Furthermore, STPN is robust for loss of objects in some extent and can effectively avoid long time disparity of media synchronization, especially, in case of high loss rate of media objects.Read More
