Detects this and sends a control signal to turn off the audio of the main screen from the wireless transmission unit 43 to the control unit 20 of the television receiver 1.
Output to The control unit 20 receives the signal and turns off the power of the main screen audio processing circuit 24. Thereby, the sound of the speaker 29 stops. Here, when the user wants to hear the sound of the main screen with the headphones 3, the main screen sound is selected by the operation switch of the remote control switch circuit 41. When the main screen audio is selected, the control unit 42 detects the selection and outputs a control signal to the control unit 20 via the wireless transmission unit 43. The control unit 20 receives the signal and outputs a control signal for selecting the audio signal AV1 to the selector 18. Thereby, the audio signal of the main screen is output from the audio processing circuit 25 for the small screen, transmitted to the remote controller 2 via the wireless transmission unit 28, and applied to the headphone output terminal 39.

可能となる効果がある。As described above, according to the present invention, a video signal and an audio signal based on the output of one of the first and second tuners are put on a carrier wave and transmitted to the remote controller by the television receiver. The transmission means is provided, and the remote control is provided with the second display means for displaying an image based on the output of one of the first and second tuners. Therefore, the child screen can be displayed on the remote control, and the child screen can be displayed on the main screen. There is no need to display the screen, so that the effect of being able to view the second screen such as the counterprogram without blocking a part of the parent screen is obtained. Also, since the remote control is provided with a headphone terminal for outputting an audio signal based on the output of one of the first and second tuners, the remote control can be used without connecting the headphone cord to the headphone terminal of the television receiver. There is an effect that it is possible to listen to the television with the headphones only by connecting to the TV.
