摘要
多媒体应用的一个主要问题是对多媒体同步时间的描述和建模。文章通过引入全局时钟和对输入事件进行优先级分类,同时借鉴了TSPN的动态同步语义以及DTPN的用户交互思想,使模型可以准确描述多媒体同步时间要求,有效克服网络随机延迟和阻塞等影响。
Modeling and specifying temporal requirements of the multimedia synchronization is a key issue for distributed multimedia applications.This paper classifies the input events and use a global clock,and by using the dynamic synchronization semantic of TSPN and user interaction of DTPN for reference.This model can accurately describe the temporal requirements of the multimedia synchronization,and can handle the problem of random delay,blocking which can result in synchronization failure.
