When transmitting a digital video signal having, as a variant clock signal, a clock signal of a frequency which does not fall within a predetermined frequency range, a frequency multiplier 21 carries out a frequency conversion of the frequency of the variant clock signal so as to generate a transmit side clock signal which falls within the predetermined frequency range, and a transmitting unit transmits, as a transmission digital video signal, the digital image data and control signal, as well as the transmit side clock signal, according to this transmit side clock signal. A receive side divides the frequency of the transmit side clock signal using a frequency divider 22 to obtain the variant clock signal after acquiring the digital image data and control signal from the transmit side digital video signal according to the transmit side clock signal.
