多媒体OCPN同步模型的研究及改进

Research and improvement of OCPN synchronization model

Petri网作为一种描述系统行为的形式化工具 ,尤其擅长描述多媒体的同步问题 ,由此出现了诸如 OCPN等多媒体同步模型 ,然而 ,这些模型仅能描述多媒体之间的合成同步 ,对于解决分布式环境下的多媒体同步问题却显得不足。本文提出了一个分布式交互多媒体同步模型 ,该模型可以较好的解决分布式多媒体系统的交互与同步问题。

Petri Net is considered a formalizing tool of bewriting system action.Which is accomplished in describing multimedia synchronization problem, Such as Object Composition Petri Net model ,yet,these models are not enough for synchronization of computers in distributed conditions .This paper propose a new Distributed Interactive Object Composition Petri Net model, the model can be better dispose of interactive and synchronization problem indistributed multimedia system.
