Abstract
The inventive system mainly includes a synchronization marker at a transmitting site and a synchronization forcer at a receiving site connecting to each other via computer networks. The synchronization marker performs the sequential mark marking of frames per every marking interval. The synchronization forcer regulates the play time of the audio signals and their corresponding video signals according to their sequential marks. The inventive system can determine precisely about the minimum marking interval yielding a bounded skew requirement. Consequently, the invention satisfies any given skew requirement under various buffer size and traffic arrivals while imposing minimal overhead.
