This remote control 80 is, of course,
Broadcast channel selection buttons for selecting each channel of satellite broadcasting, VHF broadcasting, and UHF broadcasting have buttons 1 to N. When this broadcasting channel selection button is pressed, a broadcasting channel selection signal having a corresponding code (or frequency) is transmitted. I do. Also, when the security mode is selected and buttons 1 to N are pressed, a security information selection signal SES No. for designating security information is sent out. Similarly, after selecting the living equipment mode, buttons 1 to N are pressed. And a living equipment information selection signal LIS No. for selecting a living equipment.
These infrared signals are received by a remote control terminal 90 disposed on the ceiling of the room, and the remote control terminal 90 includes a television mode selection signal TVS, a broadcast channel selection signal TV-CHS, and a monitor mode among the received infrared signals. Select signal MNS,
Monitor selection signal MN-CHS and video mode selection signal VTR
S transmits wirelessly to the TV receiver 50 (infrared rays, radio waves, etc.), converts the security information selection signal SES No. and the living equipment information selection signal LIF No. into data signals,
Put on 0.

The security device monitoring device 20 monitors output states of various security devices such as an output of a lock detector that detects locking of a window, an output of a fire alarm, and an output of a gas leak detector. When an access signal is received from the control unit CPU 3, which will be described later, data containing the “status” of the accessed security device is transmitted to the control unit CPU 3 via the data bus 40.

The living equipment control device 30 is, for example, a controller of an air conditioner, and has a data converter for converting a start / stop command signal generated by operating a start / stop push button of the controller into data. Upon receiving an access signal from the control unit CPU 3 described later, the unit sends operation / stop data to the control unit CPU 1 via the data bus 40.

In FIG. 2, television waves captured by a VHF antenna 11 are input to TV tuners VHFCH1, 3, 4, 6, 8 to 12 for each channel through a VHF distributor 11A, and the video of each channel selected here is displayed. Signals (including audio signals) are supplied to corresponding input ports of the video signal processing unit 2. UH
The TV radio waves captured by the F antenna 12 are input to the TV tuners UHFCH1 to UHFCHN for each channel through the UHF distributor 12A. Are supplied to the corresponding input ports. In the same way, the TV radio wave captured by the BS antenna 13 passes through the BS distributor 13A and is transmitted to the TV for each channel.
The video signals (including the audio signal) of each channel selected here are input to the tuners BS1 and BS2, and are supplied to the corresponding input ports of the video signal processing unit 2. The video signals transmitted by the door phone camera 14 and the monitor cameras 14 and 15 are also input to the corresponding input ports of the video signal processing unit 2. VTR7
The reproduced video signal transmitted by 0 is also input to the input port corresponding to the video signal processing unit 2.

The video signal processing unit 2 receives the video signal of each channel of the satellite television broadcast, the video signal of each channel of the VHF television broadcast, the video signal of each channel of the UHF television broadcast,
Each video signal of a door phone camera or a monitor camera, a playback video signal of a video tape recorder are subjected to signal processing to be described later and transmitted, and for each of the transmitted video signals, an RF modulator 4BS1, 4BS2, 4VHF1 ~ 4VHF1
2, 4UHF1-4VHFN, 4MN1-4MN2, 4VTR, after assigning any different frequency in radio frequency RF, mixer 5
The multiplexing is performed by frequency division, and the multiplexed signal is transmitted to the coaxial cable 60.

The “status” data of the security device, the “status” data (run / stop data, etc.) of the household appliance control device transmitted to the data bus 40, and the security information selection signal SES
The No. and living equipment information selection signal LIS No. are taken into the control unit (comprising a microprocessor) CPU3.

The CPU 3 operates the remote controller 80 to transmit, for example, the lock security selection signal SES No. (No. 1) to the data bus.
When received through the data bus 40, the security device monitoring device 20 receives an access signal for obtaining a locked state from the data bus 40.
The security device monitoring device 20 that has received the access signal returns the number (code) of the door or window that is not locked to the CPU 3. CP that received this return
U3 creates this door or window number and image data indicating that the door or window of that number is "unlocked" (or forgotten to lock), and gives it to the video signal processing unit 2 together with the command. The video processing unit 2 performs signal processing on the image data, and performs a superimpose process on all of the captured video signals from a television or a monitor camera.

In addition, the remote control 80 can be used to select the living device information
When No. 1 (No. 1 is assumed to be an air conditioner) is received through the data bus 40, an access signal for obtaining an operation / stop state is sent to the controller unit of each air conditioner 30 through the data bus 40. In response to the access signal, the controller unit of each air conditioner returns data of "operating" if operating, and "not operating" if stopped, to the CPU 3 together with the number (code) of the air conditioner. The CPU 3 that has received the return creates image data including the “number” and “state” of each air conditioner, and provides the image data to the video signal processing unit 2 together with the image division display command. The video processing signal processing unit 2 performs signal processing on the image data and outputs one of the captured video signals.
A process for inserting the image data into a part of the frame is performed.

When receiving the TV mode selection signal TVS and the broadcast channel selection signal TV-CHS (for example, four channels of VHF), the TV receiver 50 receives the TV mode selection signal TVS and the broadcast channel selection signal TV-CHS from the multiplexed signal transmitted through the coaxial cable 60. It tunes to the output frequency of the RF modulator 4VHF4 and displays a video signal with this frequency on the screen.

In this state, the CPU 3 sends the locking security selection signal SES No. (No. 1) to the data bus 40 as described above.
When the security device monitoring device 20 is accessed to obtain information that the door or window of a certain number is unlocked, the information is given to the video signal processing unit 2 as image data. For example, this security information is displayed on a quarter screen (FIG. 3A).

When the fire detector detects a fire and the gas leak detector detects a gas leak among the security devices, the security device monitoring device 20 notifies the fire or gas leak without waiting for access from the CPU 3. Sends (or interrupts) alarm data to CPU3. The CPU 3 having received the alarm data gives the image data to the video signal processing unit 2 together with the superimpose command, and displays the image data on the screen of the TV receiver 50 as shown in FIG. 3 (b), for example.

The video signals of the intercom camera 14 and the monitor camera 15 may be configured to be displayed on a part of the screen by performing screen division display, picture-in-picture or superimposition processing.

〔The invention's effect〕

As described above, the present invention combines a video signal of a television broadcast or a monitor camera with an image signal of security information or household equipment information in a video signal processing unit, and then passes through a mixer to a coaxial to which a receiver is connected. With the configuration of sending to the cable, if the broadcast television channel or monitor video / channel is specified by the button operation of the information selection unit, the receiver tunes to the frequency of the specified channel and displays the video of that channel And in this state,
By specifying the security information by the button operation, for example, the security information can be displayed on a part of the screen of the receiver, and one receiver can be used for multiple purposes. Even if the monitoring system described above is introduced, there is an advantage that only one commercially available receiver can be used.
