摘　　要：采用图像处理器Hi3516A作为媒体处理平台设计了基于实时流协议的视频处理系统,首先对高清图像传感器采集到的原始视频图像数据按照H.265进行压缩编码,然后将编码后的数据按照实时流协议进行成帧、包封,最后通过以太网接口发送到IP网络中.测试结果表明,视频处理系统具有占用网络传输带宽低、传输延迟小、视频流畅等特点,能满足高清网络视频监控的需求.The video processing system based on real-time streaming protocol uses Hi3516A image processor as media processing platform. It firstly compresses and codes the original video image data captured by the HD image sensor according to H. 265, then puts the encoded data into frame and encapsulation in accordance with the real-time streaming protocol, and finally sends it to the IP network through the Ethemet interface. The test shows that the video processing system has the characteristics of low network transmission bandwidth, low transmission delay and smooth video display and so on, which can meet the needs of HD network video surveillance.
