音视频的合成与同步在网络监控系统中的实现

The Implementation of Synthesization and Synchronization of the Audio and Videoin Network Video Surveillance System

为了满足社会各行业对网络视频监控系统的需求,提高服务质量,在描述服务器端MPEG 1视频压缩卡的过程中,提出了在LINUX平台硬件设备中保证音视频合成与同步的系统设计及实现原理,使应用程序不仅能从驱动程序中得到音视频数据,还能得到音视频数据的同步信息,以合成系统流.

In order to meet the needs of the Network video surveillance system in social application and improve the quality of the service, during the course of the implementation of the MPEG1 compression,the author brings forward a kind of method of the design and implementation to guarantee the synthesization and synchronization of the audio and video data. The applications can get not only the audio and video data from the driver, but also the synchronization information of the audio and video data.
