  • Patent number: 6166776
    Abstract: There is provided a multi-receiving demodulator for receiving broadcasting signals from multiple broadcasting systems. The multi-receiving demodulator has a first band pass filter for selectively band-pass-filtering an intermediate frequency output from a tuner to obtain a color subcarrier corresponding to the broadcasting system of a received signal, according to a first control signal, and a second band pass filter for selectively band-pass-filtering the intermediate frequency output from the tuner to obtain an audio carrier corresponding to the broadcasting system of the received signal, according to a second control signal. A video demodulating portion receives the color subcarrier from the first band pass filter and selectively demodulates a video signal corresponding to the broadcasting system of the received signal in accordance with the second control signal.
