PROBLEM TO BE SOLVED: To provide a satellite signal reception/transmission system capable of receiving CS left and right polarization signals in addition to BS (broadcasting satellite) without providing a downconverter at a receiving end. SOLUTION: Frequencies are made high in the order of a BS signal, a CS right polarization signal and a CS left polarization signal for arrangement, the signals are separated on a frequency axis and transmitted through one signal cable 7b, the signal cable 7b is fetched into a dwelling unit, the fetched signal cable 7b is connected to a switching distributor 4 to be distributed to a plurality of outputs, and each of the distributed outputs is connected to a television terminal 11 of each room. In the switching distributor 4, a first distributor 2 distributes an inputted signal into two outputs, one of the distributed outputs is distributed into four outputs and connected to a first output port P1 of an output switching means 16, and the other of the distributed outputs is made to pass through a downconverter part 13 for downconverting the CS left polarization and then connected to a second output port P2 of the output switching means 16. The output switching means 16 is switched by a voltage signal sent from a CS tuner 8 connected to the television terminal 11. COPYRIGHT: (C)2004,JPO
