PURPOSE:To eliminate necessity for a coaxial cable when receiving any new video signals and to enable the use of a reception system 1 by providing a video signal output device inside a broadcasting receiver, selecting the desired video signal while using this device, and transmitting it to a television receiver after the output is modulated. CONSTITUTION:In the case of newly receiving the broadcasting of satellite broadcasting CS or CATV to be individually received at home when the video signals receiving at present are VHF or UHF broadcasting, for example, the video signal output device is provided corresponding to these kinds of broadcasting. Namely, a satellite broadcasting receiver 21 of the video signal output device, for example, is operated as a CS tuner, and the CS broadcasting received by an antenna is outputted as video signals. Therefore, the video signal receiver is composed of a modulator 22 for modulating the frequency of the idle channel of a UHF band and a mixer 24 for mixing the output of an amplifier 23 for VHF, UHF or BS broadcasting under receiving at present with the modulated output signal, and the signals are transmitted to the receivers of each room by using a distributor 28.
