摘要
多媒体同步是多媒体应用的一个重要需求，这已为众多研究人员所共识。多媒体同步的一个主要问题是多媒体同步时间要求的描述和建模。本文在克服当前多媒体同步模型局限性的基础上，提出了一个新的基于时间Ｐｅｔｒｉ网的多媒体同步模型－－ＭＳＴＰ模型，它能使多媒体系统依据实际运行时的延迟和多媒体动态同步类型，以更准确、高效的方式来保持多媒体同步。
Multimedia synchronization has been recognized by many researchers as a significant requirement for multimedia applications. Modeling and specifying timing requirements of the multimedia synchronization is a main problem of multimedia synchronization. In this paper, on the basis of overcoming the limitations of the proposed models, a new multimedia synchronization model, MSTP based on timed Petri-net, has been proposed. This model can let the multimedia system keep the multimedia synchronization in a more precise and effective manner, according to the real run time situation of delay and the new proposed types of multimedia dynamic synchronization.
