Proposes a media synchronization method for MPEG video stored in distributed databases in a computer network. The proposed method takes account not only of the video frame synchronization but also of the played-back frame sequence quality. First, we propose a quality measure for moving pictures based on the smoothness of motion, which makes use of motion vectors between frames. Then a synchronization method for MPEG video, based on such a quality measure, is proposed, and its performance is evaluated by a computer simulation, by comparing it with other media synchronization methods for MPEG video.
