摘　　要：针对多路混合型硬盘录像机系统中多路摄像机视频的接入和处理问题,在基于服务器和编码板卡构架的HVR系统基础上提出了可靠高效的多路视频接入和处理软件方案,并实现了此方案。在多路视频接入和处理中,需对多通道视频并行处理及同一视频通道同时执行多个功能,针对此过程中可能存在的资源冲突问题进行了优化,提出了完善的多通道并发操作及视频码流分发机制、功能会话安全结束机制。测试结果表明,应用该软件方案的系统可接入能力强,资源占用率低、系统稳定可靠。Point at the complex channel video connecting and processing question in Hybrid Video Record system, the paper gave a reliably and high efficiency way to realize the complex channel video connecting and processing in the Hybrid Video Record system, which based on the hardware structure of server mainboard and encoding card. To deal with the problem of the resource conflicting while multi-channel video signal processing and performing several functions in one channel at the same time, designed a perfect mechanism of the parallel operation to multi-channel and the video stream distributing as well as how to exit one function safely. By the actual prove, the designing makes the system have high ability of the video connecting ,low occupancy rate of system resources, high quality of video and stability of performance.
