<p>A converter device (110) converts radio waves of a receiving medium received by an antenna device (100) into a common intermediate frequency signal, and transmits the signal to a demodulating/decoding device (130) by an IF signal cable (140). In the demodulating/decoding device (130), the intermediate frequency signal outputted from the converter device (110) is switched by a switching circuit (135) to demodulating/decoding circuits (136-138) of the receiving medium selected by own system so as to be outputted.</p> |
