A MULTIMEDIA SYNCHRONIZATION DYNAMIC MODEL FOR DISTRIBUTED MULTIMEDIA SYSTEMS

In distributed multimedia systems,the characteristics of multimedia synchronization is dynamic,and the key medium has the priority in multimedia synchronization.The proposed multimedia synchronization models can not meet these requirements.So a new multimedia dynamic synchronization model,DSPN,based on timed Petri net,has been designed.This model can not only let the distributed multimedia system keep the multimedia synchronization in a more precise and effective manner according to the run time situation of the system,but also allow the user to interact with the presentation of multimedia.
