Abstract:

In the traditional videoprocessing platform with detached DSP(Digital Signal Processor) and ARM(Advanced RISC Machines) processors, there is some disadvantages such as large print circuit board, the small amount data access capacity and the difficulties for exchanging data. A new method is provided with DaVinci platform for an embedded video surveillance system, which is achieved with a dualcore processor chip DM6446. The realization is introduced in three function blocks, one is embedded Web server, another is encoding for video capture and video transmission, the last one is about protocol stack for network communication. The video surveillance system is built up in B/S(Browse/Server) architecture. The functions are fitted into ARM and DSP core processor correspondingly, which leads the best performance optimization on one chip.
