Transmitter that wirelessly transmits various information according to the input operation by 1a
1b and a transmitting antenna 1c. Reference numeral 2 denotes a door-to-door receiver installed in each home, which receives a transmission signal from the base station 1. Reference numeral 3 is a television receiver for general households installed near the door-to-door receiver 2.

When it is not necessary to operate the television receiver 3 via the door-to-door receiver 2, the base station 1 transmits required information in the same signal form as the conventional one (mainly audio information). Information in this case is generated from the information signal generating unit 11 of the console 1a, and transmitted from the transmitting antenna 1c via the transmitting unit 1b. Therefore, the operation of the door-to-door receiver 2 in this case is the same as the conventional operation. On the other hand, when the base station 1 needs to operate the TV receiver via the door-to-door receiver 2 due to an emergency situation or the like, the base station 1 remotely operates the TV receiver 3 from the remote control signal generator 12 of the console 1a. To generate a signal for
The signal is transmitted from the transmission antenna 1c via 1b. Here, the signal used for remote operation is a signal for turning on the power of the television receiver 3 and a signal for setting a channel to a designated channel. Based on the above signal, a remote control signal for the television receiver 3 is generated on the side of the door-to-door receiver 2 which will be described later.

The meaning of setting the channel to the designated channel is based on the assumption that the television broadcasting related to the emergency situation is performed on the channel. In addition,
Apart from the above, only a signal for turning on the power of the television receiver 3 may be transmitted as a signal to be used for remote control, and the channel setting may be left to the viewer on the side of the door receiver 2. In this case, the broadcast channel may be transmitted from the base station 1 as audio information (information signal generating section 11). The above is the case where the television receiver 3 is turned on, the channel is set, and the image is displayed by television broadcasting. However, in addition to this, the image information such as a still image, a moving image or a character is transmitted to the base. There is also a configuration in which the image is transmitted from the station 1, reproduced by the door-to-door receiver 2 and displayed on the television receiver 3. Specifically, the base station 1 causes the information signal generator 11 to generate the video information, and the remote control signal generator 12 sets the signal for turning on the power of the television receiver 3 and the external video input mode. Signals are generated, and these signals are transmitted from the transmission unit 1b via the transmission antenna 1c. The transmission signal has control data and information data, the signal used for the remote operation is assigned to the control data, and the signal used for the audio information or video display is assigned to the information data.

The signal transmitted from the transmitter 1b of the base station 1 is received by the reception antenna 2a of the door-to-door receiver 2. The door-to-door receiver 2 generates a remote control signal (for example, infrared ray) for power-on and channel setting based on the received signal and transmits it to the television receiver 3. As a result, the television receiver 3 is powered on and set to the designated channel. When the signal transmitted as described above is only the signal for powering on, the viewer sets the channel.
When the signal transmitted from the base station 1 is a power-on signal, an external video input mode setting signal, and a video signal, the door-to-door receiver 2 uses the received signal to power-on and external video. A remote control signal for input mode setting is generated and transmitted to the television receiver 3, while the video signal is reproduced, and the same video signal is output to the video output terminal of the door-to-door receiver 2 and the external video input terminal of the television receiver 3. It sends out through the connecting cable between. As a result, the television receiver 3 is powered on, set in the external video input mode, and displayed as a video.

It is a control unit that controls each unit illustrated. The transmission signal from the base station 1 is received by the reception antenna 2a of the door-to-door receiver 2 (ST1) and input to the reception unit 21. Based on the signal received by the receiving unit 21, the control unit 28 determines the various types of determination described below.
Let's do it at 26. First, the determination unit 26 determines whether or not the control data of the received signal includes a signal for remote operation (ST.
2). When this judgment is made without the signal for remote operation (ST2-
N), the receiving unit 21 in the audio signal processing unit 22 as in the conventional case
The audio signal is reproduced based on the information data of the signal from (3), and the speaker (SP) 23 is driven by the audio signal (ST3).

On the other hand, if the determination is that there is a remote control signal (ST2-Y), the determination unit 26 next determines whether the information data of the signal from the reception unit 21 includes video data (ST4). If the video data is not present, it is further determined whether or not the information data includes audio data (ST5). If there is voice data in this determination (ST5-Y), the control unit 28
Generates a power-on remote control signal on the basis of the power-on signal included in the control data of the signal from the receiving section 21 in the remote-control signal generating section 24, and causes the light-emitting section 24a to receive a light-receiving section (not shown) of the television receiver 3. (ST3), the audio signal processing section 22 reproduces an audio signal in the same manner as in (ST3) and drives the speaker 23 (ST6). As a result, the television receiver 3 is powered on, and the set broadcast channel is transmitted from the speaker 23. Further, when there is no audio data (ST5-N), the control unit 28 controls the remote control signal generation unit 24 based on the power-on signal and the channel setting signal included in the control data of the signal from the reception unit 21. A power-on remote control signal and a channel setting remote control signal are generated and transmitted from the light emitting section 24a to the light receiving section of the television receiver 3 (ST7). As a result, the television receiver 3 is powered on and the broadcast channel is set to the designated channel.

If there is video data (ST4-
Y), the control unit 28 is a receiving unit in the remote control signal generating unit 24.
Generates a power-on remote control signal and an external video input mode setting remote control signal based on the power on signal and the external video input mode setting signal included in the control data of the signal from the 21 While transmitting to the light receiving section of the television receiver 3, the video signal processing section 25 reproduces the video signal and sends it to a predetermined external video input of the television receiver 3 via a connection cable (ST8). As a result, the television receiver 3 is powered on and the video transmitted from the base station 1 is displayed. Further, the remote control signal generated by the remote control signal generation unit 24 must match the remote control signal form of the television receiver 3. That is, the form of the remote control signal differs depending on the television receiver manufacturer. Therefore, the remote control signal generation unit 24 stores various types of remote control signals in a built-in memory in advance, and the setting unit 27 selects and sets a desired form from the stored various types of remote control signals. To Alternatively, the remote control signal generation unit 24 receives a remote control signal dedicated to the television receiver 3, and operates the setting unit 27 to store it in the built-in memory in advance. Although FIG. 2 described above has a configuration including the video signal processing unit 25, in the case where the base station 1 does not transmit the video information, the video signal processing unit 25 becomes unnecessary and the processing of (ST8) in FIG. There will be nothing. Although the remote control signal is infrared in the above description of FIGS. 1 and 2, it may be a wireless signal instead. in this case. 1 and 2
The “light emitting unit” and the “light receiving unit” of “” are the “transmitting unit” and the “receiving unit”, respectively.
