Research And Application Of Streaming Media Technology In Campus Video Surveillance System

With increasing public awareness of social security, network videosurveillance system slowly popularity in various public places. In particular,the rapid development of multimedia technology, how to make full use of theexisting campus network platform to enhance network performance, especiallyby means of the existing network, build safe campus, effectively enhance thecampus property, life safety is worthy of further study. And the developmentof education in China, the scale of universities is growing, increasing thenumber of students, campus openness and logistics services are alsoincreasingly high degree of socialization, school management and safety andsecurity issues facing the new campus HD Network video surveillance systemalso highlights the unlimited business opportunities.In this paper, the main advantages related technologies and theintroduction of intelligent video surveillance video surveillance systems,analyze intelligence as a precondition to the campus surveillance systemrequirements and design at the same time; they describe the streaming videotransmission control algorithms and algorithms: by improving QoS policy,network QoS control, and error control caching mechanism to improve thetransmission quality; the characteristics and methods of MPEG-4compressedfiles for analysis and to explore research and application of streaming mediatechnology in the campus video surveillance system.For streaming media technology on campus video surveillance, the papermade the following related work:First, by analyzing the research status of video surveillance systems, aswell as comparison of three generations of video surveillance systems, tounderstand the necessity of the development of intelligent video surveillancetechnology, draw critical current video surveillance development are: digital,networked, intelligent. Then introduced the related technology of intelligentvideo surveillance systems, streaming media technology and videocompression coding technology in video surveillance, analysis of thedevelopment trend of intelligent video surveillance systems. Then, through thecampus video surveillance system the meaning of existence, function, features, advantages, and demand a detailed analysis, detailing the design of the systemarchitecture, reflecting its importance and value. And by how to use videocompression coding technology due to post-processing multimedia informationgenerated by digital compression and transmission of massive datatransmission to improve the video processing capabilities. Finally, the overallstructure of the streaming media campus surveillance system design, while itsanalysis of system hardware and software environment and campussurveillance system for the realization of the main modules and applicationsystems were described, analyzed to determine the feasibility of the system.
