交互式多媒体动态同步Petri网模型——扩展的IMDSPN

Interactive Multimedia Dynamic Synchronization Petri Net Model——An Extended IMDSPN

将优先权输入事件Petri网引入到IMDSPN模型中,建立了D-IMDSPN模型。D-IMDSPN模型可以解决在分布式多媒体环境中,出现在用户交互作用下的媒体来源于各种资源或是要到达多个目的地时的异步,以更高效的方式保证了多媒体同步。

A D-IMDSPN model is constructed by introducing prioritized Petri Net to IMDSPN in this paper. D-IMDSPN model can settle the problems of asynchronisms that come from all kinds of sources or arrival at the sinks in interactive distributed multimedia environment, thus can ensure multimedia synchronization in a more efficient way.
