Research And Implementation Of P2P Network Video Surveillance System Based On Coding Route Protection

In this dissertation, it studies the protection of P2P network video surveillance peripheral terminals, and to protect the security of data transmission path based coding technology.First, the current situation and insufficient network video transmission within the scope of the current design of the Internet to solve the coordination of access to the terminal and image compression and transmission problems, this paper proposes a network-based image transmission system of centralized P2P. In this paper, a combination of image acquisition, embedded OS, computer network communications and other fields related to technology, using centralized coordinated P2P network topology, the use of standard JPEG image compression method, each distal end of the range within the Internet for networking and management. Paper uses a coding-based coding path protection scheme. In the network, node failure or link failure is inevitable, network failures and data security transmission problems caused by them should be taken seriously, for the WAN link failure leads to data loss problems, this paper presents a coding based protection scheme, named for the encoding path protection (CPP). In the CPP, the backup copy of the primary data with other data stream to be encoded, resulting in the capacity savings.Finally, the system design of the database, creating a website, data display, data transmission network, data storage, query and other functions, to provide users with visual platform.Thesis writing process successfully built a model of the system to achieve using this prototype system to provide users with online operations services, which can effectively reduce the impact of network channel and location brings. The results show that the system is running well, with a time-saving, high efficiency, centralized management of distributed implementation, etc., and can achieve the desired objectives. The last stage of this paper summarizes the work conclusion, contact future technology development, improvement in the direction of the svstem were discussed.
