| Abstract: | The real time true color video signal is often processed with digitizer in supervisory control, desktop video and all sorts of microcomputer image processing system.According to the features of the digital video monitoring system based on digital video decoder Bt848,the newest developed PCI local bus is used in image capturing. This paper describes the realization of the image capturing and video editing of the monitoring system based on PCI bus, PCI bus specification, principle of the digital video decoding and the development of user software. Besides, part of source program developed with VC++4.2 is given. |
