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.
