Enhancement of simultaneous output-timing control with human perception of synchronization errors among multiple destinations

This paper proposes a method to enhance simultaneous output-timing control with human perception of synchronization errors among multiple destinations. This purpose is to improve the interactivity. In the conventional control, the destinations try to synchronize their output timings of media streams with a destination which has the latest output timing so that all the destinations can easily output information simultaneously. Instead of synchronizing the output timings of media streams exactly in the conventional control, the enhanced control improves the quality of intra-stream and inter-stream synchronization and the interactivity by allowing group (or inter-destination) synchronization errors among the destinations.
