送受信機。[Scope of Claim for Utility Model Registration] (1) In a receiver capable of receiving BS broadcasts and CS broadcasts, an audio digital signal reproducing circuit and an audio analog signal reproducing circuit are connected to respective input terminals of a switching device. , providing means for extracting the frame synchronization detection signal from the audio digital signal reproduction circuit and inputting it to a microcomputer, and inputting the output signal from the microcomputer to the control terminal of the switching device, so that the frame synchronization detection signal is not detected. Sometimes, the switch is switched so that the switch outputs a signal from the audio analog signal reproducing circuit, and when the frame synchronization detection signal is detected, the switch is switched and the switch detects the frame synchronization detection signal. A satellite broadcasting receiver characterized in that it outputs a signal from a circuit that is connected to a satellite. (2) The satellite broadcasting receiver according to claim (1), wherein a plurality of reproduction circuits for the audio digital signal are provided, and each reproduction circuit reproduces a signal of a different audio reproduction method. (3) providing a display means and connecting it to the microcomputer;
The satellite according to claims (1) and (2), characterized in that the reproduction method of the audio being reproduced is displayed on the display means based on a frame synchronization detection signal from the audio digital signal reproduction circuit input to the microcomputer. Broadcast receiver.
