A video signal processing circuit includes a frame memory to receive and store therein at a first rate each frame of a digital video signal in which additional information is assigned separately to each frame, a frame synchronization unit to read each frame of the digital video signal from the frame memory at a second rate, and a processing unit to assign the additional information to the digital video signal read by the frame synchronization unit, without repeating the additional information when the frame synchronization unit reads a same frame of the digital video signal repeatedly, and without skipping the additional information when the frame synchronization unit reads by skipping a frame of the digital video signal.
