By confirming the order, the order confirmation data 1 (consisting of the terminal ID and the user ID) in FIG. 3 is transmitted to the response server 40 (step S1).
3). At this stage, it is not necessary to send specific order information. The response server 40 serves as a bridge between the user and a sales company that actually sells the goods, various service companies, an information providing company, a television broadcasting station, a broadcasting station that provides information through a telephone line, and the like, and a plurality of them exist. To do.

After the telephone line is disconnected, after waiting for reception from the response server 40 (step S14), if the encrypted user information cannot be received within a predetermined time,
The process ends (steps S16 and S17). When the encrypted user information can be received (step S15), the user information is displayed by decrypting the encrypted user information using the previously received decryption key information (step S18) (step S19). ). This allows the user to confirm that the order has been received.

By making a connection request to the response server 40 and transmitting the order confirmation data 2 (terminal ID, user ID, password, ordered article information), a specific order is placed (step S20). This completes the order processing (step S21).

Next, the operation of the response server 40 will be described.
The response server 40 is ready to receive the connection from the terminal of the individual user via the telephone line (step S).
31). The connection is confirmed from the individual user, the order confirmation data 1 is received (step S32), the terminal ID is extracted from this and transmitted to the personal information server 50 (step S3).
3).

The transmission from the personal information server 50 is awaited (step S34), and if it cannot be received within a predetermined time, the line is disconnected (steps S36 and 37).

From the personal information server 50, encrypted user information (service company code, terminal ID, user ID,
When the encrypted personal address, name and other information) is received (step S38), it is transferred to the user. When the order confirmation data is received from the user (step S39), the encrypted terminal ID / product data (terminal ID, user ID, encrypted password,
The information (including the ordered article information) is extracted and transmitted to the personal information server 50 (step S40). It waits for reception from the personal information server 50 (step S41), and if it cannot be received within a predetermined time, the processing is completed (step S4).
3, 44).

When the user information (name, telephone number, address, etc.) is received from the personal information server 50, it is transmitted to the article sales company as order information (step S4).
5) The order receiving process is completed (step S46). The article sales company 70 receives this, sends the article to the individual user, and collects the price from the user.

The credit card number may be provided as user information to complete the payment.

Here, even if the response server collates the order confirmation data 1 and 2 with the user information, the encryption method is not always the same, so a user who has a specific address and name with one order Can confirm that he / she purchased a specific item, but at the stage of receiving the order confirmation data 1 and 2 in the next order, it is not possible to identify which user made the order,
It is possible to protect users.

Next, the operation of the personal information server 50 will be described. The personal information server 50 transmits the decryption key information to each user (step S51), and is in a state of waiting for reception from the response server 40 (step S52).

The decryption key information may be provided to the user on a regular basis or may be provided each time an order is received.

When the terminal ID data is received from the response server 40 (step S53), the user information is retrieved from the database provided in the personal information server 50 (step S54) and encrypted (step S55) to obtain the encrypted user information. (Service company code, terminal ID, user ID, encrypted personal address, name, and other information) are transmitted to the response server 40 (step S).
56).

This is sent to the user via the response server 40 to confirm the order to the user,
When a specific order from the user is received as a terminal ID / product data via the response server (step S5)
7) The user information is searched in the database (step S58), and this is transmitted to the response server 40 (step S59). As a result, one order personal information server 50
Operation is completed.

The encryption is determined by the speed of data communication and the size of personal information.

Further, although the personal information is provided to the response server 40 twice, the way of providing the personal information is not limited to this embodiment. There is no problem even if more information is encrypted during the first data transmission (order confirmation data 1).

Hereinafter, embodiments of the bidirectional data communication apparatus according to the present invention will be described in detail with reference to the drawings.

The address database may be provided in the terminal itself. Here, FIG. 9 shows a user's selection method, and the address is fixed by cursor selection on the selection screen as shown in FIG. 9B.

The address database has a hierarchical structure as shown in FIG. 10, and a more detailed address list is selected by the user's selection.

(Embodiment 4) Next, the operation of connecting the two-way data communication device 10 to the personal information server 50 via the telephone line 30 and updating the personal data will be described.

The operation of the individual user will be described with reference to the flowchart of FIG. When the user has changed the user information such as the telephone number, the device ID of the two-way data communication device 10, and the address, and the procedure has been completed, the change flag is not set (step S141) and the change flag is set. If not, it is in a state of waiting for a connection from the personal information server 50 (step S142).

If the change flag is set, it is determined that the change registration in the personal information server 50 has not been completed, and the procedure is completed (step S141).

When connected (step S143), the changed user information is sent to the personal information server 50 via the telephone line, and the procedure is completed (steps S145, 147).

The specific flow of this procedure is as described in the above embodiment. If the connection cannot be established, it is found that the change registration with the personal information server has not been completed, and the procedure is completed (step S146).

Next, the operation of the personal information server will be described with reference to the flowchart of FIG. Personal information server 50
Makes a connection request from the terminal of the individual user via the telephone line (step S1302), confirms the connection (step S1303), and thereby receives the device ID and the user information (step S1304). The user information such as the device ID in the database of the information server is compared (step S1305).

When the collation is impossible, a change flag is set in the database of the personal information server and the connection is terminated.

When the user information has not been changed and when the changed information is re-registered, this information is stored and the procedure is completed. The specific flow of this procedure is as shown in the flowchart of FIG. 5 shown in the second embodiment, and in step (131) of FIG. 7, the completion of registration is displayed and the change plug is not set up. Put in a state. The operation of the personal information server at the time of re-registration is as shown in the flowchart of FIG.

It becomes possible to change personal information such as address and telephone number on a regular basis.

Embodiments of a bidirectional data communication apparatus according to the present invention will be described in detail below with reference to the drawings.

(Fifth Embodiment) FIG. 13 is a block diagram showing an electrical configuration of a bidirectional data communication apparatus according to the fifth embodiment.

In FIG. 13, Embodiments 1, 2, 3,
The same functions as those in No. 4 are given the same numbers.
Further, the description of the configuration having the same function is omitted.

Reference numeral 40 denotes a response server interactively (bidirectionally) connected to the NCU 24 of the bidirectional data communication apparatus 10 via the telephone line 30, and 50 denotes the bidirectional data communication apparatus 10 via the telephone line 30. NCU24
A personal information server 60 is interactively (interactively) connected to the response server 40, and a television broadcasting station 60. Although not shown, there are a plurality of response servers 40, and each response server 40 is connected to the personal information server 50 via the telephone line 30. Also,
Each response server 40 and personal information server 50 are connected to the television broadcasting station 60 via the telephone line 30.

First, the operation of initial registration of user personal information will be described. Usually, when the two-way data communication device 10 is purchased or when an online service contract is concluded, initial registration of user personal information to the personal information server 50 is performed. This initial registration is performed via the telephone line 30. That is, the user operates the operation input unit 20.
Is operated to display a personal information registration menu on the display unit 19, and a user registration request is sent to the personal information server 50 together with the terminal ID through the modem 22 and the telephone line 30 by key operation. The terminal ID is stored in the ROM 12. Upon receiving this, the personal information server 50 downloads the registration program to the two-way data communication device 10 via the telephone line 30. The program is RAM13
Stored in. The user can operate his / her name / address /
Enter personal information such as phone number, date of birth, and gender.
The personal information is sent to the personal information server 50 via the telephone line 30 and stored in the hard disk. Of the personal information, the birthday based on the date of birth is registered in the RAM 13 of the two-way data communication device 10. Next, the personal information server 50 automatically dials the registered telephone number to confirm the registration completion, sends the user ID from the personal information server 50, and the two-way data communication device 10 registers the received user ID in the RAM 13. After that, delete the registered program. It should be noted that the registration program is stored in advance in the memory of the terminal, and without downloading from the personal information server, the personal information can be input at the terminal,
After that, it is also possible to perform registration processing to the personal information server via the telephone line.

As described above, the user information such as name, address, and telephone number is registered in the personal information server 50 together with the user ID, and the two-way data communication device 10
That is, the user's birthday as a predetermined date is registered in the RAM 13.

Next, a general operation of receiving a data broadcast program will be described. The video signal receiving unit 15 selects from the received TV signals, sends the TV signal of the reception channel to the video switching unit 17, and at the same time the data broadcast decoder unit 1
Send to 6. The data broadcast decoder unit 16 separates and decodes the data broadcast signal superimposed in the vertical blanking period of the selected video signal, sends it to the RAM 13, and temporarily stores it. The display control unit 18 controls the video switching unit 17, and sends either the video signal of the television broadcast from the video signal receiving unit 15 or the data broadcast signal read from the RAM 13 to the display unit 19. The display control unit 18 is also the display unit 1.
The display mode in 9 is controlled to be full screen or two screens, and character data is scroll-displayed as a telop on the lower side or the upper side of the full screen.
The control performed by the display control unit 18 is determined by an input command from the operation input unit 20.

When the content of the program related to the data broadcasting is, for example, a quiz program or variety program or a questionnaire survey in which the viewer participates, the user performs an operation of selecting one from preset answers and issues an automatic dial command. When issued, C
The PU 11 automatically dials the response server 40 via the modem 22, the NCU 24, and the telephone line 30, and provides reply information to the response server 40. The response server 40 processes the information as needed and communicates the result to the broadcasting station 60 via a telephone line.

Next, a brief description will be given of the operation in the case of performing online shopping by looking at the contents of the television broadcast or the transmission information from the response server. The transmitted product information is displayed on the display unit 19. When order confirmation is instructed by operating the operation input unit 20, the order confirmation data (terminal ID
-User ID / password / ordered product information) is transmitted to the response server 40 via the telephone line 30, and the order processing is completed. The response server 40 is the personal information server 50.
To the personal information server 50, the user personal information (name, address, telephone number, etc.) is received, and this is transmitted to the product sales company as order information.
Complete the order processing. The product sales company sends the ordered product to the corresponding user based on the user's personal information and collects the price from the user.

Next, the operation of displaying the birthday message will be described. As described above, the RAM 13 of the two-way data communication device 10 stores the data of the user's birthday, and the personal information server 50 stores the user's birthday data.
User personal information such as name, address, and telephone number is registered with D. A birthday message is constantly transmitted from the television broadcasting station 60 by a broadcast wave. The birthday message includes a message indicating that the birthday has arrived and a message for recommending renewal registration due to a change in user personal information. For example, "Happy birthday. Please update if there is any change in your name, address, telephone number, etc.". The birthday message is superimposed on the vertical blanking period of the broadcast wave. This birthday message is always received by the two-way data communication device 10, but is not displayed until the birthday comes.

As shown in the flow chart of FIG. 14, when the bidirectional data communication device 10 is powered on, the CPU 1
1 determines whether the current date and time based on the built-in timer has reached the birthday registered in the RAM 13, that is, the birthday or a day after that (step S151), and if not, it is born. Although the display of the day message is prohibited (step S155), when the birthday is reached, it is determined whether the birthday is within one month, for example (step S152). Display the birthday message decrypted by
9 is displayed (step S153). With this, the birthday message is displayed every time the power of the two-way data communication device 10 is turned on for one month after the birthday. Wait until the time is up (step S15
4) The display of the birthday message is prohibited (stopped) (step S155). The user sees this birthday message, and the personal information such as his / her current name / address / phone number is already registered in the personal information server 50.
You will be prompted to decide whether it has changed from the phone number, etc., and if it has changed, you will be prompted to renew. If it has been more than one month since the birthday, it is assumed that the message has already been transmitted to the user and the birthday message is not displayed (step S15).
5).

When the personal information is changed, the user updates and registers the personal information with the personal information server 50. With this, the online service can be continuously provided.

By the way, displaying the birthday message for one month after the birthday is annoying to the user. This is solved by the operation shown in the flowchart of FIG. When the user wants to prevent the birthday message from being displayed, the user operates the delete key in the operation input unit 20 (remote control). The CPU 11 determines whether or not the erase key has been operated (step S1401), and when the erase key has been operated, resets the display flag F ₁ (step S1402).
Then, in the flowchart of FIG. 14, step S1
52a is added, and the birthday message is displayed only when the display flag F ₁ is set (step S
153) If the display flag F ₁ is reset, the birthday message is not displayed (step S155).

If the display flag F ₁ is kept reset, the birthday message will not be displayed when the birthday of the next year comes. Therefore, as shown in FIG. 15B, it is determined whether or not 11 months have passed since the birthday (step S1501), and when it has passed, the display flag F ₁ is returned to the set state (step S150).
2). Then, the determination in step S152a is YES, and the birthday message is displayed again.

(Embodiment 6) The content of the birthday message in the case of the above-mentioned Embodiment 5 is "Please update if there is a change in name, address, telephone number, etc."
It was such content. On the other hand, it may be possible to display personal information such as a specific name, address, and telephone number that has already been registered. In other words, as a birthday message, for example, "Congratulations on your birthday. Your registered name / address / phone number is ..., ..., ...
… But are there any changes? If there are any changes,
Please register for renewal. Is the content. The fifth embodiment displays the birthday message having such contents. The birthday message including such personal information is transmitted from the personal information server 50, not from the broadcasting station 60. Therefore, the message is not sent constantly, but only when requested.

The operation will be described with reference to the flowchart of FIG. When the power of the bidirectional data communication device 10 is turned on, C
In PU11, the current date and time based on the built-in timer is RAM1.
It is judged whether or not the birthday registered in No. 3 has been reached (step S1601), and if not, the operation is ended. It is determined (step S1602) that the operation is ended if it is over one month, but if it is within one month, the personal information server 50 is automatically dialed through the telephone line 30. At this time, the terminal ID is sent and a birthday message transmission request is made (step S160).
3). Then, it waits for reception from the personal information server 50 (step S1604). When there is a birthday message transmission request from the two-way data communication device 10, the personal information server 50 sends the birthday message including the personal information to the two-way data communication device 10 having the requested terminal ID. Send. In the two-way data communication device 10, the birthday message including the received personal information is stored in the RAM 13 (step S1605), and the birthday message is displayed on the display unit 19 (step S160).
6). With this, the birthday message is displayed every time the power of the two-way data communication device 10 is turned on for one month after the birthday. After the time is up (step S1607), the birthday message display is stopped (step S1608), and the birthday message is deleted from the RAM 13 (step S1609). The user sees the birthday message specifically containing the personal information such as name, address and telephone number, and the personal information such as the current name, address and telephone number and the name already registered in the personal information server 50.・ Comparison and comparison with personal information such as address and telephone number will be performed very clearly, and you will be strongly encouraged to judge whether it has changed, and if it has changed, you will be prompted to update and register. If it is more than one month after the birthday, no message transmission request is sent to the personal information server 50.

When it is desired to prohibit the display of the birthday message for one month after the birthday message is confirmed, the delete key may be operated to perform the same processing as in FIG.

(Embodiment 7) In Embodiment 7, a birthday message is received from the response server 40 instead of the personal information server 50. The birthday message in this case does not include specific personal information such as name, address, telephone number, etc. As with broadcast waves, the general message "Happy birthday. Your name and address.・ If there is a change in the telephone number, please update and register. "

As the operation, in the flow chart of FIG. 16, “in personal information server” is replaced with “in response server” in step S1603, and in step S1605, “birthday message including personal information” is replaced with “birthday message”. Message ".

(Embodiment 8) In the embodiment 8, instead of receiving a birthday message from the outside, the birthday message is issued inside the two-way data communication device 10. That is, when the birthday message is written in advance in the ROM 12 and the current date and time becomes the birthday according to the date and time judgment of the CPU 11 (and one month after that), RO
The birthday message is read from M12 and displayed on the display unit 19. In the case of this embodiment, the ROM 1
2 requires a large memory capacity, but the control of the message display is extremely simple.

(Ninth Embodiment) The above fifth to fifth embodiments
In 8, the birthday data is registered in the RAM 13 by operating the operation input unit 20. This is so that the bidirectional data communication device 10 can determine whether or not the current date and time is the birthday. Basically, since the birthday is the birthday of the user of the interactive data communication device 10, the interactive data communication device 1
There is an idea that it is natural to register a birthday at 0. However, if there is a power failure or the outlet is unplugged, the birthday data will disappear from the RAM 13. If that happens, you will have to register the birthday again, but this will bother the user and can be forgotten.

Therefore, it is possible to register birthday data in the personal information server 50 and have the personal information server 50 manage whether or not the birthday has arrived. This is followed in the ninth embodiment described below.

In the personal information server 50, in addition to the name, address and telephone number, the date of birth (birthday) of the user,
It is assumed that user personal information such as a terminal ID has been registered. The CPU of the personal information server 50 determines whether or not the current date and time based on the built-in timer has reached the registered birthday, and when the date and time has arrived, sends the corresponding terminal ID and message transmission command to the broadcasting station 60. Send out. The broadcasting station 60 sends the received terminal ID and birthday message on a broadcast wave. As a general rule, this processing shall be performed from the date of birth to one month.

The operation will be described with reference to the flowchart of FIG. In the two-way data communication device 10, the CPU 1
1 judges whether or not the terminal ID is received from the broadcasting station 60 when the power is turned on (step S1701), and when the terminal ID is received, the received terminal ID is compared with the terminal ID read from the ROM 12 (step S1702). If the two terminal IDs match as a result of the comparison (YES in step S1703), the birthday message received from the broadcasting station 60 is displayed on the display unit 19 (step S170).
4). The birthday message displayed at this time is normal. For example, as described above, "Congratulations on your birthday. If you have any changes in your name, address, telephone number, etc., please update and register." Is the content.

(Embodiment 10) In a model in which birthday data is not registered in the RAM 13 of the two-way data communication device 10, a method of displaying a birthday message including personal information as a birthday message may be considered. This is the ninth embodiment. The birthday message including the personal information is obtained by accessing the personal information server 50. That is, steps S1701 to S170 of FIG.
3 is followed by steps S1603 to S1609 in FIG.
Is configured to perform.

In the bidirectional data communication device 10, the CP
U11 determines whether or not the terminal ID is received from the broadcasting station 60 when the power is turned on (step S1701), and when the terminal ID is received, the received terminal ID is compared with the terminal ID read from the ROM 12 (step S1702). As a result of the comparison, when the two terminal IDs match (YES in step S1703), the personal information server 50 is automatically dialed via the telephone line 30. At this time, as shown in FIG. 16, a birthday message transmission request is made together with the terminal ID (step S1603). And
Wait for reception from the personal information server 50 (step S1)
604). When there is a birthday message transmission request from the two-way data communication device 10, the personal information server 50 sends the birthday message including personal information such as name, address, and telephone number to both of the terminal IDs that requested the birthday message. The data is transmitted to the data communication device 10. Two-way data communication device 1
At 0, the birthday message including the received personal information is stored in the RAM 13 (step S1605), and the birthday message is displayed on the display unit 19 (step S1606). With this, the birthday message is displayed every time the power of the two-way data communication device 10 is turned on for one month after the birthday. After the time is up (step S1607), the birthday message display is stopped (step S1608), and the birthday message is deleted from the RAM 13 (step S1609).

(Embodiment 11) The above-mentioned Embodiment 9
In FIG. 10, after the user confirms the birthday message or the birthday message including the personal information, the user can eliminate the annoyance of displaying the message for one month from the birthday.

As in the case of FIG. 15, when the user wants to prevent the birthday message from being displayed, the user operates the delete key on the operation input unit 20 (remote control).
As shown in FIG. 15A, the CPU 11 determines whether or not the erase key has been operated (step S1401), and when the erase key has been operated, the display flag F ₁ is reset (step S1402). Then, step S1703a is added to the flowchart of FIG. 18, the birthday message is displayed only when the display flag F ₁ is set (step S1704), and when the display flag F ₁ is reset, it is born. The day message is not displayed (step S1706). Display flag F ₁
If is left reset, the birthday message will not be displayed when the birthday of the next year arrives.

Therefore, as shown in FIG. 15B, it is judged whether, for example, 11 months have passed since the birthday (step S1501), and when it has passed, the display flag F ₁
