ジユレータ。[Scope of claim for utility model registration] Switching between supplying a broadcast signal to a television receiver or supplying a signal from a modulator that modulates video and audio signals into high-frequency signals that can be input to the antenna terminal of a television receiver. A modulator with a switch having a high frequency switch, comprising: a first switching means for switching whether a first input broadcast signal is supplied to the high frequency switch or output to the outside; and the first switching means is connected to the first input. When a broadcast signal is supplied to the high frequency switch, the switch is turned off, and when the first switching means outputs the first input broadcast signal to the outside, it is turned on, thereby outputting a second input broadcast signal from the outside. A modulator with a switch, comprising a second switching means for supplying a signal to the high frequency switch.
