| Abstract: | Aiming at the needs of high stable and robust multimedia digital surveillance system,a four-channel real-time MPEG-4 video capturing and processing PCI board based on TMS320DM642 is designed and implemented.The hardware architecture of TMS320DM642 DSP,the hardware structure of the PCI board and implemention of core module sections are described.The difficulty and key technique during the PCB design are analyzed.Experiment simulation shows that the PCI board can fulfill the demands of four-channel video image capturing,real-time encoding and data transmission via PCI interface without decreasing of video quality.It provides the hardware support for remote surveillance system and has a comprehensive market prospect. |
