摘要:	Building a web-based distributed multimedia presentation system environment is a technical challenge .In this paper, we described how to present different multimedia objects on a web presentation system with floor control mechanism as a result of the distributed environment indispensably. The distributed approach is based on an extended timed Petri net model. Using characterization of extended time Petri net, we introduce the concepts of user interaction. The main goal of our system is to provide a feasible method to represent different multimedia objects with user interaction and floor control mode. In addition, users can dynamically request different kinds of conditions during the presentation. To verify the structural mechanism, we implement an algorithm using the Extend Time Petri net model. Futhremore, we consider the interactive facilities to support the distributed communication requirement. We specified a floor control algorithm based on Z notation, which provides four types of control (free access, equal control, group discussion, and direct contact). These control mechanisms are sufficient to the use of distance learning environment.
