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