Design And Implementation Of Wireless Video Monitoring System Based On H.265

In recent years,with the rapid development of China's society and economy,security systems is particularly important in China and even the world.Review the past decade,in the field of video coding,most of the video coding standards used on the market are mainly H.264.But with the rapid development of current high-definition,intelligent and networked,H.264 can't fully meet their needs.By studying the existing video surveillance system,this paper designs a kind of wireless video monitoring system based on H.265.The system mainly consists of two parts which are respectively the monitoring server and monitoring client.The system has the advantages of clearer rendered images,higher coding efficiency and more stable performance,etc.It also overcomes the problem of cable monitoring system of large area of wiring.This design mainly finished the following several aspects of research work:1.This paper makes a detailed analysis of the video compression coding algorithm for H.265,wireless transmission medium,and streaming media transmission protocol RTP/RTCP protocol RTSP session that used in the system development.2.Research and study the Hi3516A's architecture,features,basic components and commonly used peripheral modules.This paper designs the overall scheme of the system and the main hardware's circuit design.The embedded video server platform construction of monitoring camera,involving the transplanting of Bootloader,the transplantation of the Linux kernel and file system YAFFS2 production.4.Develop the media processing software in monitoring the server-side,including video capture,video processing,video coding and multimedia processing platform for the realization of the MPP.5.The development of video transmission,including the development of the application on UDP transmission protocol RTP and RTSP session agreement.The 4G module driver transplant and implementation to realize the monitoring server and the client for 4G wireless signal transmission way.6.To realize the H.265 compressed video signal decodino through receiving the video signal inn monitoring client implementation and the FFmpeg development;to realize the display of the video signal through the Directdraw development;to realize the monitor video target detection through the OpenCV development.7.Test the whole system through connecting each module and analyze the test results.The results show that after combining the new generation of video coding H.265 and 4G wireless transmission fuses in together,the wireless video monitoring system can run normally,and has the real time and high compressibility.
