Abstract:
A satellite-broadcasting receiving converter comprising:a plurality of output terminals each of which can be connected to an external receiver, to each of which any one of four types of selection control voltages specified according to the combinations of high and low DC voltages and whether a high-frequency voltage having a predetermined frequency is superposed is separately sent from the external receiver, and from each of which a satellite-broadcasting receiving signal of a type selected according to the selection control voltage is separately output to the external receiver; signal selection means for selecting one type of a receiving signal according to the selection control voltage from four types of satellite-broadcasting receiving signals different in modulation-signal form and polarization direction from each other for each output terminal to output it; a regulator for receiving the selection control voltage sent from each output terminal in common and for converting the selection control voltage to a predetermined power-source voltage to output it; and a plurality of high-frequency attenuation means each connected in series between each output terminal and an input end of said regulator.
