The Design And Realization Of Video Monitor System Software Based On DM642

In today's society, the application of security technology becomes more and more extensive. While, with the development of society and green city construction, people apply to the security industries for a higher request. Because the tradditional network video monitor system only saves mass of video data, which causes huge burden to network channel and storage. In order to improve the quality and efficiency, and achieve the goal of high request, this paper suggests a new method for network video monitor system, selective to encode the video data and transmit it to clients who do save, which reduces the burden of network channel and storage.After analysis of the H.264 video encoding algorithm, this paper gives the thought of the monitor system and introduces some tools which used to design the system software. This new programme will realized basd on the model of client/server, most functions will completed in the server.With the intelligent analysis algorithm and the status of the TCP connection, the DSP server will be adaptive to deal with the video data. and the client complies with the server to save encoded video data then renames the file with time information according to the move informations coming from server port. The whole design process is implemented based on platform SEED-DTK-VPM642 which used TI's DSP chip TMS320DM642。This paper completes the software design of the monitor system with tools as following, CCS,NDK,RF5 and VC++6.0. Server part includes four tasks, video input and intelligent analysis task, local show task, video encoding task, and network transmission task. Client part is realized based on VC++6.0 with multithread for data receive. The experiment demonstrates this method is available and the performance is stable.
