Image combination processing system arranged in display

An image blending system built in a display, including a video input module, a video routing unit, a regional image processing unit, a terminal image blending unit and a display terminal unit,

• wherein the video input module comprises n video input units, and each of them has multiple video input channels and a device ID;
• the terminal image blending unit identifies type of the video input signals and version information of the video input units according to the device ID, and the video input signals are converted to high-speed serial signals through the video input units;
• the video routing unit switches matrix switch array according to instructions transmitted by the control chip of the terminal image blending unit, and then transmits the high-speed serial signals from the different channels of the video input module to the corresponding regional image processing unit;
• the regional image processing unit receives and stores the high-speed serial signals, and scales, crops or blend these signals, and then the processed video signals are transmitted to the terminal image blending unit;
• the terminal image blending unit integrates the input video signals to high resolution signals and transmits the signals to the display terminal unit.
