[Abstract]:Nowadays, real-time video surveillance system has been widely used in various fields of human life because of its intuitive, accurate, real-time and easy to manage, etc. Because of the large amount of data transmitted by real-time video surveillance system. At the same time, the real-time requirement of data stream transmission is very strict. It is very important to study how to ensure the real-time and reliable transmission of video stream in the network. Firstly, this paper analyzes H.264 coding compression technology and RTP / RTCP. the core search algorithm of H.264 is optimized and the coding efficiency is improved. The real-time performance of video stream transmission is enhanced. The video stream transmission framework based on RTP H.264 is analyzed and the RTP packaging scheme is proposed. Secondly, the overall design and implementation of the monitoring system is given, and the acquisition and coding part is given. The streaming media server and the streaming media client are introduced respectively, the construction of the streaming media server and the packaging and sending process of the RTP are analyzed in detail, and the congestion control based on the RTCP feedback is added to improve the QoS. The H.264 video stream transmission under UDP/RTP protocol is realized. Finally, the test system is built to test and verify the transmission scheme. Through the verification, the system is clear, smooth and real-time. The video stream transmission method designed in this paper meets the requirements of practical applications.
