In order to realize the test of multi channel DVI video signal based on high speed avionics bus, the design scheme of airborne multichannel DVI video signal distributor is proposed. According to the characteristics of electric bus multichannel DVI video signal rate high speed, realtime and multiway, complete video signal conversion module, signal shunt module circuit design, realize data acquisition processing and shunt gigabit network video signal transmitting function. The experimental results show that the airborne high speed bus Video Splitter without affecting the original video link condition, solve the highspeed shunt avionics bus multichannel DVI video signal drawing requirements.
