In recent years, researchers have tried to extend Petri net to model multimedia. The focus of the research flows from the synchronization of multimedia without user interactions, to interactions in distributed environments (Bastian, 1994; Blakowski, 1996; Diaz, 1993; Guan, 1998; Huang, 1998; Huang, 1996; Little, 1990; Nicolaou, 1990; Prabhakaran, 1993; Prabhat, 1996; Qazi, 1993; Woo, 1994). The issues that concern us are the flexibility and compactness of the model. Petri net extensions have been developed to facilitate user interactions (UI) in distributed environments; however, they require sophisticated pre-planning to lay out detailed schedule changes. In this article, we introduce a Reconfigurable Petri Net (RPN).
