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.
