<p>Since attenuation compensation amount operating means (60, 61, 62, 63, 67, 68, 69, 70) of a signal receiver operate the attenuation compensation amounts (GL, GH) of a video signal based on the attenuation of pulses arranged in a digital voice signal LRD from a signal transmitter, and the video signal attenuation compensation amount operating means (60, 61) of the signal receiver compensate for attenuation of video signals (RAT, GAT, BAT) based on attenuation compensation amounts (GL, GH) thus operated, attenuation of video signals can be compensated for stably regardless of the resolution of an image or the type of a display, and a voice can be delivered to a video output unit along with a good image.</p> |
