Performance evaluation of media synchronization for multimedia presentation

In order to realize the general multimedia applications such as video-on-demand, multimedia conference and electronic museum, it is required to support variety of presentation which takes account of media synchronization. So far, we suggested a unified multimedia presentation protocol architecture considering a synchronization reference model to provide various synchronization functions depending on presentations in various applications. In this paper, we implemented a multimedia conference system which concurrently provides both live and stored presentations based on our proposed architecture and evaluated performance of lip synchronization method in the prototype system. As results, our synchronization method could provide effect and correct media presentation
