一种视音频同步系统的综合解决方案

A new synchronization solution for real-time video and audio transmission system

本文详细讨论了一种适合于实际应用的视音频传输同步系统的设计原理和实现方法。设计注重提高整体同步系统的性能,根据视频及音频媒体流产生异步的位置,结合在应用中的媒体流的处理,提出了从四个方面采用并行机制解决同步问题的方法,即从采集编码、网络发送、接收、回放端来同时解决,这样将同步问题分散到四个部分解决,降低复杂度,提高了资源使用率。同时由于四个部分同时进行同步调整,降低了系统的延时。

The design principle and the realization method of synchronization for real-time video and audio transmission system are discussed. This design pays attention to improve the performance of whole synchronization system. According to the causation of asynchrony and the method of processing media streaming, the method is put forward that four ways are adopted in parallel mode, synchronization can be simultaneously solved from coding, sending, receiving and playing modules. So synchronization can be solved from these four parts. Complexity and system load are both reduced. At the same time, the system delay is also decreased.
