本発明はテレビジョン受像機に関し、特にビデオ信号入
力端子を持つテレビジョン受＠機に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a television receiver, and particularly to a television receiver having a video signal input terminal.

ようになっていた。Conventionally, in television receivers (hereinafter referred to as TV receivers) that have an external video signal input terminal and can switch between broadcast television signals and external video signals, this input switching is done using a manual input switch provided on the TV receiver. It was supposed to be switched by.

を受信中にＶＴＲを見ようとづ−るとＶＴＲとＴＶ受像
機の双方を操作しなければならないという欠点がある。As mentioned above, conventional TV receivers switch between broadcast TV signals, external video signals, and a manual input switch. When looking at
All you have to do is operate the VTR (you have to manually switch between the TV receiver and the input, which is a lot of work twice). In other words, even though conventional TV receivers are equipped with external video signal input terminals, they do not take into account operations in which the TV receiver operates in conjunction with the operation of the VTR, which is the case when used in combination with a VTR. There is a drawback in that if you want to watch a VTR while receiving a signal, you have to operate both the VTR and the TV receiver.

次に、図面を参照して本発明について説明する。Means for Solving the Problems] The TV receiver of the present invention is controlled by an input terminal for inputting an external video signal from the outside and a DC signal superimposed on the external video signal, and is controlled by a DC signal superimposed on the external video signal. Embodiment 1 Next, the present invention will be described with reference to the drawings.

。Capacitors 22 and 12 are used to separate this direct current from the video signal. The relay driver 13 drives the coil 14 of the relay by the sent DC current, and the coil 14 moves by 15 minutes, and the video amplifier 16
The signal it receives is switched from the output signal of the tuner and video detection section 17 to the input signal I\ of the video signal input terminal 11. ■When T R2 is not regenerating, no DC is supplied,
Relays are not driven. If the type of switch 15 is such that the contact connected to the tuner and video detection section 17 is broken and the contact connected to the capacitor 12 is made, then when the VTR 2 is not playing, or
When video signal cable 3 is not in use,
The Sui-Sochi 15 automatically switches to receive broadcast television signals and can be used as a regular TV receiver.

In addition, when used in combination with a VTR that does not have the function of supplying direct current, the functions of the present invention cannot be achieved;
All you need to do is to be able to learn H15.
