摘要
在分布多媒体系统中,多媒体具有动态同步特性,同时关键媒体的同步要求在应用中享有优先权.现有的多媒体同步模型无法满足这些要求,现提出一个新的基于时间Petri网的多媒体动态同步模型——DSPN模型.它不仅能使分布多媒体系统依据实际运行状况和新提出的同步类型,以更准确、高效的方式来保持多媒体同步,而且允许用户对多媒体表现过程进行交互操作.
In distributed multimedia systems,the characteristics of multimedia synchronization is dynamic,and the key medium has the priority in multimedia synchronization.The proposed multimedia synchronization models can not meet these requirements.So a new multimedia dynamic synchronization model,DSPN,based on timed Petri net,has been designed.This model can not only let the distributed multimedia system keep the multimedia synchronization in a more precise and effective manner according to the run time situation of the system,but also allow the user to interact with the presentation of multimedia.
