| Abstract: | A design of network video server based on DM642 is proposed in this paper. DM642 is utilized as the kernel to implement the video capture, local display, compression and network transferring. The hardware structure and the software design of the system are presented. The programming of each module is described in detail. The experimental results show that the system can meet the requirements of real time and stability of network video server. There is a powerful demonstration for its future application. |
