[0005]

According to the above arrangement, the contents of a message are input from a keyboard to a personal computer or are copied by a document camera and the signals are input to the personal computer. The signal input to the personal computer is output as a video signal, modulated into an RF signal by a modulation unit, and transmitted to the television receiver of each dwelling unit via a consensus line. On the other hand, the unit to which the message is to be transmitted from the personal computer is specified. The selection signal is sent from the selection signal generation unit of the personal computer to the selection unit, and the selection unit selects the control line of the corresponding dwelling unit and turns on the short-circuit switch of the control line. The channel switching unit detects that the short-circuit switch has been turned on, and outputs a signal for switching to an empty channel. The television receiver switches the tuner in response to the switching signal, receives the signal transmitted from the personal computer, and displays the signal on the display unit. When the transmission of the message is completed, the personal computer stops transmitting the video signal and stops transmitting the selection signal, so that the selector turns off the switch. The channel switching unit detects the switch-off, transmits a channel return signal, and returns the television receiver to the original channel.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a block diagram showing one embodiment of a message circulation system for an apartment house according to the present invention. In the drawing, reference numeral 4 denotes a document camera, which copies the contents to be transmitted and inputs it to the A / D converter 3. Reference numeral 3 denotes an A / D converter, which samples a video signal from a document camera, converts the signal into a digital signal, and outputs one screen. Reference numeral 2 denotes an input unit for inputting contents to be transmitted and designation of a dwelling unit from a keyboard. Reference numeral 6 denotes a storage unit that stores signals from the A / D conversion unit 3 and the input unit 2. Reference numeral 5 denotes a character generator which converts a character code signal in a storage unit into a character pattern. A display unit 1 displays the camera data in the storage unit and the character data of the message content. Reference numeral 8 denotes a synchronizing signal generator which generates a vertical / horizontal synchronizing signal required for a video signal. Reference numeral 9 denotes a D / A conversion unit, and the storage unit 6
The character data of the message content is taken out through the character generator 5, D / A converted, converted into an analog signal through a filter, amplified and output. Reference numeral 11 denotes a synthesizing unit that synthesizes the signals of the synchronizing signal generator 8 and the D / A converter 9 and outputs a composite video signal. 10
Is a selection signal generation unit that outputs a signal for selecting a corresponding dwelling unit based on dwelling unit designation data in the storage unit 6. 7 is a control unit,
The A / D converter 3, the input unit 2, the storage unit 6, the character generator 5, the display unit 1, the synchronization signal generator 8, the D / A converter 9, the synthesizer 11, and the selection signal generator 10 are controlled. Reference numeral 14 denotes a personal computer, which is composed of various units controlled by the control unit 7. Numeral 12 denotes a modulating unit which converts the video signal from the synthesizing unit 11 into an RF signal of an empty channel (U / V channel) of the television.
Modulate into a signal. Numeral 15 denotes a management room, and numeral 19 denotes each dwelling unit. A selection unit 13 includes a switch corresponding to each dwelling unit, receives a selection signal for selecting a dwelling unit from the selection signal generation unit 10, and turns on a corresponding dwelling unit. 1
Reference numeral 8 denotes a channel switching unit, which is installed in each dwelling unit 19, and a control terminal of the channel switching unit 18 is connected to a switch of the selection unit 13 via a control line 20. When the control terminal of the channel switching unit 18 is turned on, a signal for switching to an empty channel of the television is output, and when the control terminal is turned off, the television receiver 7 is turned off.
To return to the original channel. Reference numeral 16 denotes a coaxial line, which is a coaxial cable for transmitting a signal from a television receiving antenna to the television receiver 17 in each dwelling unit, and superimposes an output signal of the modulation unit 12. 1
Reference numeral 7 denotes a television receiver, which is installed in each dwelling unit, receives a channel switching signal from the channel switching unit 18, switches the channel, and receives a signal from the consensus line 16.

In the above configuration, when there is a message to the resident, the manager inputs the message content from the input unit 2. Alternatively, the contents of the message are copied by the document camera 4 and input via the A / D converter 3. The input data is stored in the storage unit 6 and displayed on the display unit 1. When it is desired to transmit the message contents to the resident of the corresponding dwelling unit, a desired signal is input from the keyboard of the input unit 2 and the selection signal is output from the selection signal generation unit 10 and the message data in the storage unit 6 is synthesized. The video signal is output from the unit 11. Selection unit 13 that has received the selection signal
Turns on the switch of the dwelling unit specified by the selection signal. When the switch is turned on, the channel switching unit 18 sends a signal for switching to an empty channel, for example, two channels, to the television receiver 17, and the television receiver 17 switches the tuner to two channels. On the other hand, the video signal transmitted from the synthesizing unit 11 is modulated into an empty channel, for example, two channels by the modulation unit 12 and transmitted to the consensus line 16. As described above, the message content from the personal computer 14 is displayed on the television receiver 17. When the transmission of the message is completed, the personal computer 14 stops transmitting the selection signal.
3 turns off the switch. The channel switching unit 18 detects the switch-off of the selection unit 13 and outputs a channel return signal to the television receiver 17, and the television receiver 17 switches the tuner to the original channel. Note that the channel switching unit 18 may transmit a channel switching signal to the television receiver 17 as an infrared signal instead of transmitting the signal via a cable, and perform remote control. Although not shown, the selection unit 13 may be replaced with a telephone exchange to select each dwelling unit.

[0008]

As described above, according to the present invention, a TV receiver selected from the TV receivers installed in each dwelling unit is transmitted from the personal computer via the consensus line, and the selected TV receiver is transmitted. Since the message is copied to the machine, the message content is transmitted to the other party as characters or pictures and has the advantage of being correctly understood.
