ABSTRACT:
A CATV selection device adapted to convert the desired CATV signal into a vacant channel frequency of the TV set and to deliver the vacant channel frequency as an output to make it possible to watch the desired CATV broadcasting. The device has an input terminal adapted to receive both of the TV broadcasting signal and the CATV broadcasting signal, an output terminal for delivering the broadcasting signal to the input terminal of a TV set, a conversion circuit adapted to receive the CATV broadcasting signal corresponding to the selected channel into the vacant channel frequency of the TV set, and electronic switch circuit adapted to effect a switching between a first mode in which the broadcasting signal from said input terminal is bypassed to the output terminal and a second mode in which the same broadcasting signal is delivered to the conversion circuit, and a selection section having push buttons for selecting the desired CATV broadcasting channel and a bypass button for bypassing the broadcasting signal from the input terminal to the output terminal.
