CONSTITUTION: A satellite broadcasting receiver(100) has a transmitting antenna(104) for transmitting a broadcasting signal of a satellite broadcasting channel tuned according to the selection of a user by wireless. Each satellite broadcasting devices(110/1-110/n) has a receiving antenna(112/1-112/n) for receiving the broadcasting signal transmitted from the satellite broadcasting receiver(100). The satellite broadcasting receiver(100) responds to a user operation signal from the outside, tunes a random broadcasting channel among a plurality of satellite broadcasting channels received through a satellite receiving antenna(102), recovers the satellite broadcasting signal coded according to an MPEG algorithm as an original signal, and transmits the recovered original signal to each satellite broadcasting devices(110/1-110/n) through the transmitting antenna(104) by wireless.
