Abstract
A second audio IF signal obtained from an audio IF signal is detected to obtain an analog baseband audio signal, which is then subjected to sound volume control and muting control. A digital stereo audio signal is extracted from the second audio IF signal by a band pass filter 30, and then combined with a baseband video signal and a sound-controlled analog baseband audio signal by circuitry 21, 31. <IMAGE>
