Real-Time Transport Research And Implementation Of Network Video Surveillance System

Multimedia technology and network technology in recent years fast development, promote the wider use of digital network video monitoring system, and people's daily lives. Real-time network data transmission technology as a network digital video surveillance system is the core content is the main development of the industry. Has designed a real-time, the integrity of the video data transmission system to perform real-time streaming video in engineering applications has important value and theoretical significance.As the above thesis research background, network-based transport protocols and data transmission protocol for video transmission characteristics of the network video monitoring system in-depth research and analysis, and analyze data in real-time video network transmission. Article compared to the current widespread use of several video compression technology, and ultimately determine the compression technology systems applied to MJPEG video compression standard. Next, by comparing a variety of network data transmission protocol used by the network transport layer begin to study, after the TCP and UDP protocols do a full comparison of the development of video transmission technology solutions for the combination of multicast and RTP / RTCP / UDP protocols. Several papers analyze the composition structure below:(1) adequate research and analysis RTP Control Protocol and Real-time Transport Protocol, respectively, hereinafter referred to as the RTCP protocol and RTP protocols, and application of digital network video surveillance system requirements designed by combining the desired RTP / RTCP protocol, and verify that the latest design system protocol.(2) the transmission process, resulting in a large video image pixel data transmission is relatively large, while the higher requirements in terms of practicality, compared to traditional data transmission and video image transmission mode, which is more difficult, so the article focuses on the transmission of video the main technique used in the study and analysis, on the basis of this study was designed to send video data sub-programs and by framing algorithm restructuring video data, and finally the video transmission quality of service and buffer zones set up to do a brief analysis.(3) completed by a network of video data transmission, encoding, decoding playback, data transmission and other functions.
