In order to meet the high requirements of working temperature range of real-time video processing system in military and other areas, a real-time video processing and displaying system based on TMS320DM642 and ADV7179 is designed, including the design of hardware and software system based on DSP/BIOS. It is also innovative in putting forward a kind of scheme which makes use of TMS320DM642 GPIO interface in receiving MPEG-2 transport streams （TS）. The results of the experiment prove the reasonability and correctness of this design.
