Research Of Embedded Video Monitoring System And Client Development Player

With the rapid progress of computer networks and multimedia technology, the technology of video monitoring ,which integrates computer technology, network technology and multimedia technology ,has achieved great development. In recent years, digital video monitoring systems get more and more wide application in security areas, compared with analog video monitoring systems, they have the advantages of easy to transmit and extend and with more powerful function. There exist two kinds of digital video monitoring systems nowadays, one is based on the PC-based DVR, the other is based on the embedded video server. The embedded video monitoring system has the distinguishing features of low cost and high reliability, as well as quite good real-time feature, with it's remarkable practical utility and prospect, it has become one of the study hot in relevant areas.Upon this kind of practical requirement, the thesis devised an embedded network video-monitoring system, which is based on an embedded hardware platform of the chips of IBM PowerPC405 and Vweb2010, and based on an embedded software platform of Vxworks operating system. The advanced MPEG-4 standard is adopted in this system to realize real-time video capturing and encoding, thus high-quality images could be gotten at low bit-rate, therefore, it implements a scheme with good feature and high cost performance.Based on the scheme, this thesis designed the general architecture of the imbedded video monitoring system, and gave the sheme of the hardware and software,in addition ,it gave the development method of the BSP. After analyzing the...
