ABSTRACT:
A satellite broadcast receiver apparatus includes a plurality of signal conversion units provided corresponding to a plurality of signals transmitted from one or more satellites, each signal conversion unit frequency-converting a corresponding signal for output; a signal terminal that can input/output an electrical signal; a signal select circuit provided between the plurality of signal conversion units and the signal terminal to transmit a desired signal among the signals output from the plurality of signal conversion units to the signal terminal in accordance with a control signal applied to the signal terminal; and a power supply control unit controlling voltage supply to the plurality of signal conversion units. The power supply control unit supplies an operating voltage to at least one of the plurality of signal conversion units selected in accordance with information based on the control signal, and suppresses supply of the operating voltage to the remaining signal conversion units.
