A compositional approach to the specification of multimedia objects using Petri nets

Abstract

We propose a compositional Petri net model, called CoPN, for multimedia synchronization specifications. The salient features of this model, including macroplaces and PN entities, are presented and the application of the CoPN model to multimedia synchronization specification is discussed via some simple examples. This compositional approach enables the compact and readable specification of complex, large-scale specifications while preserving the fine granularity as well as supporting user interactions.
