A receiver receives differential analog video signals from a long distance transmission line and converts them into unbalanced analog video signals to output to an analog video signal line that is internal wiring. A frequency response characteristics corrector inside the receiver corrects the frequency response characteristics attenuated mainly by the long distance transmission line, and a delay corrector corrects differences of propagation delay. A transmitter receives the unbalanced analog video signals form the analog video signal line and converts them into balanced differential analog video signals to transmit to a long distance transmission line as differential analog video signals. A video output circuit outputs the unbalanced analog video signals or unbalanced digital video signals to a video signal line as unbalanced video signals.
