摘要:
 随着监控技术的不断发展，嵌入式视频监控系统以其占用资源少、构建灵活以及很强的扩展性得到了越来越多的应用。文中以实现实时视频监控为目的，研究了视频传输中的几项关键技术。基于TI的OMAP4430平台，充分利用其多核特性，介绍了一种基于H.264的远程视频监控系统设计方案，采用H.264的视频编解码方法比MPEG系列能够提供更高的压缩率，在很大程度上增大了带宽的利用率。在此基础上，分析了RTP/RTCP协议在视频传输中的关键参数、RTP封装等几项关键技术，并最终实现了视频的实时传输。实验结果表明该方案传输性能良好，有较高的可靠性。
Abstract:
 With the continuous development of monitoring technology, embedded video monitoring system with less resource, flexible construction and strong scalability has got more and more applications. Several important techniques of video transport are researched ai-ming at achieving real-time video surveillance. Based on TI’s OMAP4430 platform,leveraging its multi-core properties,introduce a de-sign scheme of H. 264-based remote video surveillance system,H. 264 video codec can provide higher compression rate than MPEG se-ries methods,and increase the utilization of bandwidth to a large extent. On this basis,analyze several key parameters of RTP/RTCP pro-tocol in video transmission,and the key techniques such as RTP encapsulation and so on,finally realize the real-time video transmission. Experimental results show that it has good transmission performance and high reliability.
