Abstract:

In this paper, the design principle and the realization method of synchronization for real-time video and audio transmission are discussed in detail.  In this design, in order to improve the system and network resource utilization and reduce delay,we put forward a method in which we adopt a parallel me  chanism to resolve the synchronization problem from four aspects of coding, sending, receiving and playing. Thus the synchronous processing is simplified and the synchronous system is  optimized.

Key words: video, audio, parallel mechanism, synchronization, joint-control
