Abstract

For Multi-object Multimedia Applications(MMAs),synchronization between the media objects is an inevitable problem. Current available literature focus on transmission synchronization and only two media objects are considered. Experiments show that synchronization performance is unacceptable in MMAs without presentation stage synchronization strategy even if local media objects are played. In MMAs, each media object has its own importance and each media object pair has its own synchronization requirements. We analysis these factors in detailand quantitative criteria are given. Accordingly, synchronization performance metrics which considers these factors comprehensively is proposed. In order to ensure reasonable synchronization performance, Versatile Synchronization Strategy(VSS) is proposed.Synchronization operations of important media objectsand media object pairs with strict requirements are scheduled as the priority jobs. Experimental results show that it works well. It is a promising presentation stage synchronization strategy for MMAs.

多对象多媒体应用呈现阶段同步的需求与策略

在多对象多媒体应用(MMAs)中，媒体对象之间的同步是一个不可避免的问题。现有文献主要关注传输同步，只考虑两种介质对象。实验表明，在没有呈现阶段同步策略的mma中，即使播放本地媒体对象，同步性能也是不可接受的。在mma中，每个媒体对象都有自己的重要性，每个媒体对象对都有自己的同步要求。对这些因素进行了详细的分析，并给出了定量的判据。据此，提出了综合考虑这些因素的同步性能指标。为了保证合理的同步性能，提出了通用同步策略(VSS)。对重要媒体对象和要求严格的媒体对象对的同步操作，优先调度。实验结果表明，该方法效果良好。它是一种很有前途的综合格斗舞台同步策略。
