放送共同受信システム。[Scope of Utility Model Registration Claim] VHF, UHF television signals and satellite broadcasting television signals are each received by a master antenna, etc., and after these television signals are mixed, they are distributed to a large number of television terminals by a transmission system using coaxial cables. In the satellite broadcasting joint reception system, each television receiver separates the satellite broadcasting television signal from the mixed television signal using a dedicated tuner and converts it into a UHF empty channel for reception. The frequency of the UHF empty channel that is selectively inserted and connected to the output side of the booster that is inserted in the middle of the coaxial cable transmission system and amplifies the TV signal, and that is used to convert the satellite TV signal with the tuner. A satellite broadcasting joint reception system characterized by connecting a band rejection filter for blocking a frequency band.
