The Design Of Embedded Network Camera Based On TMS320DSC21

Along with the security coming into question, the Video Monitoring System, as the essential tool of security, has attracted the most attention. First, this paper analyzes the history and actuality of Video Monitoring System, and a new project of real time Video Monitoring System based on embedded network camera is introduced. Next, one of the key technologies of digital image process-image compression is analyzed. And one of the standard of Joint Photographic Experts Group-JPEG is chosen. The third, according to the aforementioned project, a hardware system is provided which includes the core chip-TMS320DSC21 (TI special DSP) and its peripheral circuits (clock and power supply), video input module, network output module, alarm module, and cradle head control module. The design and debug of hardware system is finished. The RTU embedded OS ucLinux, module driven program and the client software are introduced in brifef. Last, it lists the important performance parameter, test method and test result. And the structure diagram of Video Monitoring System based on network camera is present...
