Application Of H.264 Video Compression Standard In The Network Video Transmission

H.264 is the new video compression standard and has a higher compression ratio and the better network suitability. How to use the H.264 video compression standard in the network video surveillance system has become hot topic now.This paper through consults H.264 standard documents and RTP payload format for H.264 video to analyze the H.264 video compression standard's characteristic and key technologies, and analyze the technology of streaming media. Network video surveillance system, combining video code, video streaming, streaming server in one, is designed. Principle of video compression, streaming and transmission is based on to select x264 for H.264 encoding, mp4live of MPEG4IP for video's streaming and Darwin Streaming Server for streaming media server. By optimizing x264 to eliminate shadow of moving objects, x264 has better cooperation with mp4live. In the following, x264, mp4live of MPEG4IP and Darwin Streaming Server are chosen according to system which is designed. Embedded IP Camera's function is achieved by porting x264, MPEG4IP and Darwin Streaming Server to embedded Linux system based on Freescale i.MX27 and configuring them. The monitor terminal uses Mplayer to decode and play H.264 video.Finally, network video surveillance system is tested, the result show that network video surveillance system have clear video, fluent transmission and is real-time, and it can be widely used in production of video surveillance.
