关键词	A new DirectShow application in the field of LED Panel display system is shown in this paper. It realizes video processing functions with DirectShow architecture on computer. Source Filter and many Transform Filters which provided by Microsoft Co. transform source video into RGB24 format. Then the video data are scaled up/down to LED panel resolution by Fixformat Filter which inherite CTramsformfilter baseclass. After that the R/G/B values of video data are adjusted in CCorrect Filter to adapt LED Panel display. Finally the processed video is shown on LED Wall through DVI or VGA interface. Our experimental results demonstrate that this system makes a good performance. It is greatly simplify the functions of Sending-Board Receiving Board and Control-Scanning-Board in display system of the LED Wall. The total cost will be cut down observably if we can transplant the filters into the embedded platform to build a special video processing system for LED Panel display. 2009 IEEE.
