Further, the child device key input device 24 has a display element 49 and an alarm element 50 corresponding to the display element 46 and the alarm element 47 of the parent device key input device 23, and when the display element 46 and the alarm element 47 operate, It is controlled by the CPU 41 of the master device key input device 23 so as to operate in parallel with this.

The monitor 22 is a TV video signal TV from the CATV line 10.
It has a television signal receiving section 51 for receiving IN ₀ . The television signal receiving unit 51 selects one of a plurality of channel television image signals arriving from the CATV line 10 by a built-in television channel circuit, and then similarly incorporates a standard television signal. Three primary color signals RGB1 having the format of a standard television system (for example, NTSC system) television signal in the digital signal decoding circuit.
Through the switch circuit 53 of the display device 52 to the cathode ray tube (CR
T) 54, thus displaying the reproduced image of the television video signal received on the CRT 54.

Similarly, the television signal receiving unit 51 reproduces the audio signal AUD1 from the television signal received by the channel selection and supplies the audio signal AUD1 to the speaker 56 through the switch circuit 55 of the sound device 58, thereby selecting the channel. Reproduces the sound of the received TV video signal.

The reception tuning operation of the television signal receiving section 51 is controlled by the control signal CON1 of the remote control circuit 57. The remote control circuit 57 has a remote control signal RMT supplied from the master key input device 23.
The corresponding control signal CON1 is supplied to the television signal receiving section 51. At the same time, the remote control circuit 57 controls the switch circuits 53 and 55 by the control signal CON2 while controlling the television signal receiving section 51 by the control signal CON1 to output the three primary color signals RGB1. The audio signal AUD1 is supplied to the speaker 56 while being supplied to the CRT 54.

Here, in the parent device key input device 23, the key matrix 45 has a television reception mode (that is, a "television" display mode).
When the designated tuning operation is performed, the CPU 41 sends the corresponding remote control signal RMT via the input / output device 44 to control the television signal receiving section 51 to the tuning receiving state. When the key matrix 45 of the master key input device 23 is designated to the page image data reception mode (that is, the "management information" display mode), the remote control circuit 57 activates the switch circuits 53 and 55 by the control signal CON2. A switching operation is performed on the video text data processing device 21 side.

Further, the remote control circuit 57 receives the television signal by the control signals CON1 and CON2 when the key matrix 45 of the master device key input device 23 is designated in the superimpose reception mode (that is, the "screen composition" display mode). The television image signal RGB1 and the audio signal AUD1 of the unit 15 are input to the switch circuits 53 and 55. At this time, the video text data processing device 21 determines the image display signal based on the key input data input from the master key input device 23.
By alternately switching the switch circuit 53 by the superimpose bit SPI included in VTX,
The screen in which the image signal RGB2 of the image display signal VTX is superimposed on the television image signal RGB1 is displayed.

The video text data processing device 21 has a video RAM 61 for supplying an image display signal VTX to the monitor 22 and a sound generator 62 for supplying an audio signal AUD2 to the monitor 22.

The video RAM 61 obtains an image signal RGB2 for displaying a page image on the CRT 54 and a superimpose bit SPI based on the page image data coming from the communication network 2 via the modem 35.

When the CPU 31 converts the page image data into the image display signal VTX and displays it on the CRT 54 of the monitor 22, the sound generator 62 generates a sound indicating this (for example, a click sound) under the control of the CPU 31. As a result, the user can be audibly notified of the arrival of new image display data.

In this way, the terminal device from the center 3 via the communication network 2
The page image data transmitted to 1A, 1B, ...
And is displayed on the CRT 54 of the monitor 22, and at the same time, an audio signal AUD2 is generated in the sound generator 62 each time page image data arrives.

The video text data processing device 21 includes a printer 6
3. The recording device 64 is connected so that the page image data transmitted from the center 3 to the CPU 31 can be printed out and recorded.

(G2) Basic data processing procedure With the above configuration, the information system is the terminal device 1A, 1B.
In response to the request from the host computer 4, the host computer 4 of the center 3 creates device control data, and the device control data is used to generate the terminal devices 1A, 1B.
By controlling each of the devices, a responsive operation is performed so as to display a screen based on the page image data and the television image signal.

That is, in step SP1 of FIG. 9, when the user operates a desired key using the master device key input device 23 of the terminal devices 1A, 1B ..., The CPU 41 of the master device key input device 23 operates in response to the following operation. The code data corresponding to the key operated in step SP2 is sent to the video text data processing device 21 through the input / output device 44.

At this time, the CPU 31 of the video text data processing device 21 fetches the code data from the master key input device 23 through the input / output device 37 in step SP3 and converts it into a code which can communicate with the center 3 and then in step SP4. It is determined whether or not a key for controlling the function of the video text data processing device 21 itself has been operated. If a positive result is obtained here, the CPU 31 moves to the next step SP5 and executes the processing. The processing of the video text data processing device 21 itself includes a two-screen mode and a recording device.
There are processes such as recording and reproducing page image data on the 64, and printing out the data to the printer 63.

On the other hand, if a negative result is obtained in step SP4, the CPU 31 of the video text data processing device 21 moves to step SP6 and sends the key input data to the center 3 via the communication network 2.

Here, when controlling functions other than the video text data processing device 21, a request for pulling out page image data stored in the video text database 6 of the center 3, a request for inputting page image data for the entry / exit table, a dispatch center There is a vehicle dispatch request to 19, and a request to set the display mode of the monitor 22.

At this time, the host computer 4 of the center 3
After receiving and storing the key input data in SP7, the process corresponding to the key input data is executed in the next step SP8, and the page image data or the device control data is sent via the communication network 2 as a response to the request. Send back to the requesting terminal.

The center 3 stores the request data coming from the terminal device at step SP7 every time the display mode is specified, the reception channel is specified, and the page image data to be retrieved is specified from the terminal devices 1A, 1B .... By doing so, it is possible to create data for grasping the operational status of the information system.

At this time, in the terminal device, the CPU 31 of the video text data processing device 21 receives the data sent from the center 3 through the communication network 2 at step SP9, and the data sent at the next step SP10 is the device control. Judge whether it is data or not.

Here, the device control data means control data for all the devices that the host computer 4 needs to control when viewed from the host computer 4 of the center 3, and the first control item is the video text data processing device 21. 2 has an item for controlling the display mode when displaying image data on the monitor 22, and a second item for controlling the master unit key input device 23 and the slave unit key input device 24. Among the control items for the master key input device 23, the items for controlling the display element 46 and the alarm element 47 included in the master key input device 23 and the items for controlling the output of the remote control signal RMT to the monitor 22. And are included.

On the other hand, when the data transmitted from the center 3 to the video text data processing procedure 21 is not the device control data, it becomes the page image data extracted from the video text database 6 of the center 3.

Therefore, when the CPU 31 of the video text data processing device 21 obtains a negative result in step SP10, it executes step SP11.
Then, in the video RAM 61, the page image data is decoded into the image signal RGB2, and the sound generator
By driving 62, an audio signal AUD2 is generated.

At this time, the monitor 22 displays the image signal RG at step SP12.
B2 is displayed on the CRT 54 and sound is generated in the speaker 56 based on the sound signal AUD2.

On the other hand, if a positive result is obtained in step SP10,
The CPU 31 moves to step SP13 and determines whether the content of the data transmitted from the center 3 is data for controlling the output mode of the video text data processing device 21 itself. If an affirmative result is obtained here, the CPU 31 executes the processing corresponding to the transmitted output mode control data in the video text data processing device 21 in step SP14. This process is actually CP
The U31 reads the program corresponding to the transmitted output mode control data from the program ROM 33 and controls the video RAM 61 and the sound generator 62 to execute the program.

On the other hand, if a negative result is obtained in step SP13, the CPU 31 proceeds to next step SP15. This step SP1
Reference numeral 5 is a step for judging whether or not the device control data transmitted from the center 3 is control data for the master key input device 23 (and the slave key input device 24), and a negative result is obtained. This means that the content of the device control data is the control data of the printer 63 or the recording device 64 provided in the video text data processing device 21,
Accordingly, the CPU 31 moves to step SP16 and executes the control operation of the printer 63 and the recording device 64.

On the other hand, when a positive result is obtained in step SP15, this means that the content of the device control data transmitted from the center 3 is the control data for the master key input device 23, and therefore the CPU3
In step SP17, the control data is converted into a code which can be easily processed by the CPU 41 of the master key input device 23 and transmitted to the CPU 41 of the master key input device 23.

At this time, the CPU 41 receives the transmitted control data in step SP18, and then moves to step SP19. This step SP19 is a step for judging whether or not the transmitted control data is data to be processed inside the master unit key input device 23 and the slave unit key input device 24, and the master unit key input device 23 The CPU 41 executes this judgment, and when a positive result is obtained, the CPU 41 performs processing in step SP20 based on the contents of the control data. As the processing, the master unit key input device 23 and the slave unit key input device
There is a process of driving the 24 display elements 46 and 49 and the alarm elements 47 and 50. Here, the display element 49 and the alarm element 50 of the child device key input device 24 are simultaneously driven in parallel with the display element 46 and the alarm element 47 of the parent device key input device 23 under the control of the CPU 41.

On the other hand, when a negative result is obtained in step SP19, this means that the content of the transmitted device control data is not the control data of the master device key input device 23 and the slave device key input device 24 itself. It means that the CPU 41 of the master device key input device 23 is set to step SP2.
Move to 1 and send remote control signal RMT.

At this time, the remote control circuit 57 of the monitor 22 causes the remote control signal RMT at the next step SP22.
The TV signal receiving unit 51
Or a control signal CON2 for the switch circuits 53 and 55 of the display device 52 and the sound device 58.

Thus, the remote control circuit 57 receives the signal by switching the switch circuits 53 and 55 to the television signal receiving unit 51 side by selecting a channel to be received according to the content of the remote control signal RMT. The video signal is displayed on the CRT 54, and the sound is generated from the speaker 56. Further, the remote control circuit 57 uses the control signal CON2 to switch the switch circuit 53 and the switch circuit 53 according to the content of the remote control signal RMT.
By switching 55 to the video text data processing device 21 side, the image display signal VTX from the video text data processing device 21 is displayed on the CRT 54, and the sound based on the output AUD2 of the sound generator 62 is generated from the speaker 56. It
