Video processing circuit and method for handling multiple videos using single video processing path capable of increasing processing data rate and saving circuit area

A video processing circuit, comprising:

• a first memory access unit configured to read a first video source corresponding to a first pixel rate and a second video source corresponding to a second pixel rate, wherein a processing data rate of a video processing path is greater than or equal to a sum of the first pixel rate and the second pixel rate;
• and
• an image processing unit, coupled to the first memory access unit, and configured to use the processing data rate to sequentially perform image processing to a first image of the first video source and a second image of the second video source corresponding to a same display time, to generate a first processing image and a second processing image.
