Abstract (en)
A signal switching device for a satellite signal receiver includes a determination module coupled to a set-top box for receiving an instruction signal from the box and outputting a control signal correspondingly, and a switch module coupled to a plurality of signal sources for receiving a first-frequency-bandsignal, asecond-frequency-band signal and a conventional narrowband signal. The switch module outputs either the first-frequency-band signal, the second-frequency-band signal, or the conventional narrowband signal to the set-top box according to the control signal. The first-frequency-band signal and the second-frequency-band signal are respectively a vertically-polarized wideband signal and a horizontally-polarized wideband signal. The conventional narrowband signal is a vertically-polarized high-frequency signal, a vertically-polarized low-frequency signal, a horizontally-polarized low-frequency signal and a horizontally-polarized high-frequency signal.
