| Abstract: | Aimed at embedded video surveillance system consisted of high-powered video processing chip TMS320DM642 and video decoder TVP5150 of TI, this paper introduces the Class/Mini-Driver Module of DM642, and designs the device driver programs for video capturing. Further more, it provides the solution of splitting-screen problem when DM642 is capturing video. This driver program has been applied to the video surveillance system and testing result indicates that this program runs stably. |
