音声多重放送表示回路。In a television receiver that receives audio multiplex broadcasts of two audio broadcasts and stereo broadcasts in addition to monaural broadcasts, broadcast discrimination means for determining one of the audio multiplex broadcasts and derives a discrimination voltage, and audio multiplex broadcasting. It has a multiplex broadcast detection means that amplitude-demodulates the carrier wave of the sub-channel signal during reception and derives a demodulated output, and a first switching element driven by the discrimination voltage, and switching of this element causes the first display element to perform display operation. and a second switching element driven by the output from the first display means and the demodulated output from the multiplex broadcast detection means, and the switching of this element causes the second display element to an audio multiplex broadcast display circuit for a television receiver, comprising: second display means for displaying;
