On Resource Competition in Multimedia Representation

多媒休信息的表现与同步是多媒体系统,特别是多媒体电子邮件、计算机支持的协同工作虚拟现实模拟及分布式多媒体计算的关键技术。应用Petri网理论描述多媒体的同步技术刚刚起。

Advanced Object Composite PetriNet (AOCPN ) is an useful model for scheduling and synchronizing the representation of multimedia information, in this paper, we first give out the principle of multimedia representation and synchronization in the model. then discuss confliction and deadlock in multimedia information synchronization due to resource competition when scheduling,finally,a method to solve it--'Role Rule' is given out.
