Abstract: A digital video signal transmitter is provided that comprises a digital video supplier, a synchronization signal generator, and a signal generator. The digital video supplier supplies a digital video signal including effective pixel signals comprised of pixel data from an effective pixels area and blanking signals comprised of data from a blanking area. The synchronization signal generator outputs a synchronization signal which is synchronized with the digital video signal. The signal generator generates a compound video signal in which a plurality of synchronization-indication signals that indicate the timing of the synchronization signal is incorporated into the blanking signals with respect to the digital video signal and the synchronization signal.
