ABSTRACT:
In a transmitting section for a video signal transmitting/receiving system for transmitting digital video signals using a plurality of transmission channels, video guard band signals are inserted into video signals associated with the transmission channels immediately before transition from a blanking region to an effective video region. In a receiving section for the system, the inserted video guard band signals are detected for the respective transmission channels. A skew among the transmission channels is detected based on the detection result. To synchronize the video guard band signals among all the transmission channels, with reference to one of the video signals associated with a transmission channel with the longest delay (i.e., delayed by one clock cycle1T), a delay of1T is given to the other video signals. As a result, even if a skew occurs among the transmission channels, correct pixel data is displayed.
