【摘要】：时至今日,实时视频监控系统以其直观、准确、实时以及便于管理等优点已广泛应用在人类社会生活的各个领域。由于实时视频监控系统传输的数据量比较大,同时数据流传输的实时性要求比较严格,研究如何确保视频流在网络中实时、可靠的传输对监控系统有着重要的意义。本文首先深入分析了H.264编码压缩技术和实时传输协议RTP/RTCP,对H.264的核心搜索算法进行了优化,提高了编码效率,视频流传输的实时性得到增强；对基于RTP的H.264的视频流传输框架进行分析并提出了RTP打包方案。其次给出了监控系统的总体设计与实现,对采集编码部分、流媒体服务器和流媒体客户端分别进行介绍,详细分析了流媒体服务器的搭建及RTP的打包和发送过程,加入了基于RTCP反馈的拥塞控制来提高QoS,实现了UDP/RTP协议下的H.264视频流传输。最后搭建测试系统对传输方案进行测试验证。通过验证,系统画面清晰、流畅,实时性良好,本文设计的视频流传输方法满足实际应用的要求。
[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.
