Media synchronization and causality control for distributed multimedia applications

This paper proposes a media synchronization scheme with causality control f or distributed multimedia applications in which the temporal and causal rel ationships exist among media streams such as computer data, voice, and vide o. In the scheme, the Delta -causality control is performed for causality, and the Virtual-Time Rendering (VTR) algorithm, which the authors previousl y proposed, is used for media synchronization. The pa per deals with a netw orked shooting game as an example of such applications and demonstrates the effectiveness of the scheme by experiment.
