ABSTRACT:
In a satellite broadcast receiving apparatus, when a signal reception is commenced, a receiving condition of an antenna input signal is detected under such a condition that a power supply to a down-converter is interrupted, and the power from a power source is supplied to the down-converter based upon the receiving condition. A simultaneous power supply to the down-converter can be prevented, and a co-distributing system can be reliably established in a simple manner.
