Description

DETAILED DESCRIPTION OF THE INVENTION (a) Technical Field The present invention relates to a videotex communication system that determines whether or not screen information can be displayed based on the type of user.

(b1 Summary of the Invention The Videotex communication system 1 according to the present invention issues a customer card storing a customer type code to a customer using the system. When the customer card is inserted, the terminal device detects (Using) Recognizes the type of customer.When screen information is sent from the Videotex center, the information type code included in the screen information is read out and the type is recognized. The customer identification code and the information identification code are compared to determine whether or not to display this screen information.

By doing this, it is possible to set a priority for each piece of screen information and to display the screen information only to customers who meet the priority.

(C) Conventional technology and its disadvantages In the Videotex communication systems such as Captain that are currently in practical use, screen information is free screen information that can be accessed by unspecified users at will, and fees are charged for access. There is paid screen information and branch screen information that can only be accessed after accessing predetermined screen information. Such screen information is set in order to identify the user and display only what he or she wants to display.

However, forcing users, especially important users, to enter passwords such as PIN numbers leads to a decline in service, and if the user (customer) forgets the PIN number, the screen information cannot be accessed. There was a drawback.

To solve this problem, it would be possible to identify the user based on the user's first account and call up a tree that matches the user's type, but a separate search tree could be created for each type of customer. This structure has the disadvantage that tree production is expensive and maintenance is difficult.

+d) Purpose of the Invention This invention overcomes the above-mentioned drawbacks, and the terminal device collates the type of user and the type of screen information, and uses a single tree to provide appropriate information for each type of customer. The purpose of the present invention is to provide a videotex communication system capable of displaying screen information.

(e) Structure and Effects of the Invention The present invention includes a videotex center having a screen information file that stores a plurality of pieces of screen information, and a videotex center that is connected to the videotex center via a line and sends the sent screen information to a display device. A Videotex communication system comprising a terminal device for displaying information, a customer card storing a customer type code for identifying the type of customer using the Videotex communication system, and providing each of the screen information at the Videotex center. is provided with information type code adding means for adding an information type code for identifying the type of screen information, and the terminal device is provided with customer type code reading means for reading the customer type code when the customer card is accepted. , when the screen information is sent, a display possibility determining means that compares the information type code of this screen information with the read customer type code to determine whether this screen information can be displayed; The present invention is characterized by providing a screen information display means for displaying the double-sided information when it is determined that the screen information can be displayed.

As described above, according to the present invention, when a customer card is inserted by a user, the customer type code of this customer card is read. When screen information is sent from the Videotex Center, the information type code included in this screen information is read. These customer type codes and information identification codes are compared, and if the user of the terminal device is the customer to whom this screen information should be displayed, this screen information is displayed on the display.

By doing so, it is possible to select and display the optimal screen information for the user from a plurality of screen information. For example, a priority can be set for both pieces of customer one-screen information, and for each customer, screen information having a priority corresponding to that customer's priority can be displayed. As a result, screen information Wt that is desired to be displayed only to some members can be stored in the general screen information file, making it possible to diversify information provision on the screen.

(f) Embodiment FIG. 3 is an external view of a terminal device used in a Videotex communication system which is an embodiment of the present invention. The customer operation panel on the front of the device has a CRT that displays screen information.

FIG. 4 is a block diagram of a control section of the terminal device. C
PUl0 includes RoMll which stores programs etc., RΔM12 which stores data etc. via an internal bus.
Video RAM 1 that stores screen information to be displayed on the CRTI
3. NCU for communicating with the videotex center 20
/mode 1114, a keyboard interface 15 that receives input from a keyboard including a numeric keypad 2 and a start key 3, and a floppy disk 7 that stores screen information and the like. The NCU/modem 14 is connected to the videotex center 20 via a line, and the keyboard interface 15 includes the numeric keys 2. A keyboard including a start key 3 is connected. Further, a CRTl is connected to the video RAMl3.

FIG. 5 is a block diagram of the videotex center. An information processing device 21 connected to the NCU/modem 14 of the terminal device via a line is connected to a screen information file 22 for filing screen information and a screen information editing device 23 for editing screen information. Collection device 2
3 is connected to an information input device 24 for inputting information constituting screen information. When these devices edit screen information directly displayed on the screen of a terminal device, they add an information type code indicating the type of tu before the screen to the beginning of code information that is part of the screen information.

, No. 6 is a diagram showing the structure of the screen information stored in the screen information file. Screen information includes control data 200 that specifies background color, etc. Header information 201 displayed at the top of the screen. This screen information is composed of code information 203 and pattern information 204 that constitute display screen information which is the main content. At the beginning of the code information 203, an information type code of this screen information is written.

FIG. 5B is a diagram showing a state in which the above-mentioned double-sided information is displayed on the CRTI. As shown in the figure, the CRTI displays an information type code at the upper left of the screen. However, if the font color of this information type code is the same as the background color, it will not be visible to the user.Figure 7 shows a customer card (8-sama card) inserted into the card league of the terminal device. FIG. A magnetic stripe 31 is formed on this customer card 30, and a card number storage area 31a and a customer type code storage area 31b indicating the type of H customer are set on the magnetic strip.

When this card is inserted, the terminal device reads the customer type code stored in the customer type code storage area 31b and learns the priority of this customer. In addition to this method, a table corresponding to the card number of each customer card may be set in the terminal device, and the priority of the customer corresponding to the card number may be stored. In this way, there is no need to write the customer type code tα in the card, and even if the customer's priority changes, the priority change can be handled by maintaining the table of the terminal device. In this case, the card number (contents of 31a) corresponds to the customer type code of this invention.

Note that the customer type code and the information type code are composed of one-digit numbers, and the smaller the number, the higher the priority. In other words, screen information of type "1" has the highest priority as information,
It is displayed only for customers of type "1", which has the highest priority. Further, all priority screen information is displayed for customers of this type "1".

FIG. 1 is a flowchart showing the operation of the terminal device. In step nl (hereinafter, step n i will be referred to as ni), the process waits until the customer card is inserted into the card insertion slot 4. When the customer card is inserted, the card data of this card is read (n2). At this time, the customer type code of this customer card is also read. Next, a line is connected to the Videotex center (n3), and screen information is received from the Videotex center (n4). Read the information type code from this screen information (n5) and compare the customer type code read in n2 with this information type code (n
6). As a result of this verification, if the customer's priority is greater than or equal to the priority of the screen information (n?), the screen information is displayed on the CRT (n8).

On the other hand, if the customer's priority is lower than the priority of the screen information, the process proceeds to n9, and the message ``This screen cannot be serviced.'' is displayed on the CRTl. This wording is stored on floppy disk °7. After this display, a retreat code is sent to the previous HQ videotex center 20 (n1o), and the process proceeds to nil. This backward code calls up the previous screen information of the screen information that cannot be displayed.

rllll waits until the customer's next key input is available.

If a key is available, check whether that key is an end key or not.
12, and if it is the end key, disconnect the line (n1
3) Return to nl. Further, if the end key is not the key, the code input manually is sent to the center (n14) and the process returns to n4.

FIG. 2 is a flowchart showing the operation of the videotex center 20 when editing double-sided information. In n30, control information and header information of the screen are edited, and in n31, it is determined whether an information type code is added to this screen information, that is, whether an information type code has been input by the screen information editor. do. Screen information to which no information type code is added can be displayed to all users unconditionally. If the information identification code is not added to the screen information as described above, the process directly proceeds to n35, edits the following code information and pattern information, and ends the operation.

Also, when adding an information type code to screen information,
Add this 11'7 information type code to the beginning of the code information for writing characters to be displayed on the display (n32), and read from the screen control information what color is specified for the background color when displaying on the CRT ( n33). Specify the font color of the information type code to be the same color as the read background color n3
4), proceed to n35. By setting the information type code to the same color as the background color in this way, even if the information type code is assigned to the display screen information, this code will not be shown to the user.

n31 to n34 correspond to the information type code adding means of the present invention, n2 corresponds to the customer type code reading means of the present invention, n6. n7 corresponds to the display availability determining means of the present invention, and n8 corresponds to the screen information display means of the present invention.

In this way, if you use this Videotex communication system,
An information type code is set in the screen information code information to give a priority to each screen information, and a terminal device receiving this screen information can determine the priority of this screen information by reading the information type code. I did it like that. Further, a customer type code is stored in a customer card inserted into the terminal device, and the customer's priority can be determined by reading this customer type code. By comparing these type codes, it is possible to determine whether screen information can be displayed.

As a result, even if high-priority screen information, that is, screen information with a certain degree of confidentiality, is stored in the screen information file, this screen information will not be displayed to the -IQ user, so the information will not be displayed. In addition to being able to protect such high-priority information, it is now possible to provide services using Videotex's communication system, which expands the uses of the Videotex communication system and improves the ability to provide information. The system for this purpose can be simplified.
