| Abstract: | Different video sources, PAL/NTSC/SECAM, different display modes (VGA to UXGA)of PC graphic signals, or TMDS digital signal can be recognized automatically by this conversion card. Three SDRAM chip is used as frame store to fulfill the conversion of frame frequency and display resolution. In the system software design, some advanced programming methodolgy is used such as event driven and state machine based. The software has a clarity structure, which make it easy to be maintained and upgraded. |
