The average data-transmission speed is taken as the lower limit of speed  other different data-transmission speeds are selected and simulated respectively  the rule of satellite memory used is found. Basing on the relationship between data-transmission speed and memory on board  and considering the worst case  the better speed arrived. In the end  with different satellite tasks  the appropriate speeds are selected which are verified to satisfy the mission. 2011 IEEE.   DirectShow application in LED panel display system (EI CONFERENCE) 会议论文  OAI收割 2009 International Conference on Information Technology and Computer Science, ITCS 2009, July 25, 2009 - July 26, 2009, Kiev, Ukraine Tao L.; Ding T.-F. 收藏  |  浏览/下载：37/0  |  提交时间：2013/03/25 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.
