中文摘要: 针对H.323视频会议系统设计了一种基于RTP的音视频同步方法，该方法在严格遵守RTP协议的前提下，将音视频数据联系起来通过同一个媒体通道传输，从而达到唇音同步的目的。实验表明：该方法在对图像质量影响很小的情况下，很好地实现了音视频的同步播放，并且具有实现简便，不增加系统负担等优点，具有广泛的实用性。
Abstract:An RTP-based method of labial synchronization in H.323 video conference system is described. This scheme strictly obeys the RTP protocol, but brings the audio and video data into mutual connection for transmission via the same media channel, to achieve the purpose of labial synchronization. Experiments show that the scheme has not only little influence on the image quality, but also achieves a very good synchronous player of audio and video. This method is easy for operation. It has little burden on the system and can be used widely.
