Description

TECHNICAL FIELD The present invention relates to a bidirectional data communication method and a bidirectional data communication apparatus using the same.

The present invention relates to a bidirectional data communication method in a data broadcasting signal transmitted by a television broadcasting or a telephone line and a bidirectional data communication apparatus by the method, A display unit for displaying a video signal of a television broadcast or a data broadcast, and a bidirectional communication apparatus having a modem connected to a telephone line.

More particularly, the present invention relates to a two-way communication method for a system to which a response server and a personal information server are connected, and a two-way communication apparatus using the method.

1 is a block diagram showing a schematic configuration of a data broadcasting system having an interactive function. In the figure, reference numeral 1 denotes a television broadcast station, 2 denotes a data broadcast receiving apparatus serving as a television receiver having a data broadcast decoder 2a and a modem 2b, Is a response server connected to the receiving apparatus 2 via the telephone line 4 and connected to the television broadcasting station 1 via the telephone line 5. [

In the television broadcasting station 1, data of a character or a graphic form or a program for adding interactivity is coded under a determined criterion to be converted into a data signal, and a data broadcast which is assigned to a data packet by adding a synchronization code, an error correction code, Signal, and this is superimposed on the vertical blanking period (VBL) of the video signal in the same manner as the case of the character-multiplexed signal, and is converted into a radio wave to be broadcast.

In the data broadcast receiving apparatus 2, the data broadcast signal is decoded, stored and displayed in the data broadcast decoder 2a, decoded as necessary, and a predetermined process is executed. When the content of the television broadcast is, for example, a television or a questionnaire survey, a data broadcast signal includes a place of purchase, a telephone number, and a facsimile number, which are stored in a memory.

The name of the purchaser, the name of the purchaser, the name of the purchaser, the response data of the questionnaire survey and the like are added by the input means in the data broadcast receiving apparatus 2 and stored in the memory. Then, it automatically dials and transmits necessary data to the response server 3 via the telephone line 4 via the modem 2b.

In addition, the response server 3 collects orders or responses from each household, executes data processing in accordance with an instruction from the television broadcasting station 1 or an information provider or a service company prepared in advance, To the broadcasting station 1 or the information providing company or the service company. In this way, transmission and reception of data interactively (bidirectional) are performed.

When the user is provided with the online service between the data broadcast receiving apparatus 2 and the information providing company or the response server 3 of the service company, for example, in the case of online shopping, Personal information such as the user's name, address, and telephone number becomes indispensable.

However, when the personal information is maintained and managed by the response server itself, the personal information must be registered in the response server every time the response server to be used increases or whenever a response server is newly established. Registration of such personal information is cumbersome. In addition, as the number of response servers for maintaining and managing personal information increases, there is an increased risk that personal information will be unexpectedly leaked to the outside, thereby causing a problem of privacy protection.

In order to solve such unreasonableness, it is considered to establish an organization called a personal information server which unilaterally executes maintenance and management of personal information separately from an information providing company or a response server of a service company. The individual response server inquires the personal information server about the personal information of the trading partner only when the order of goods is established. By keeping and managing the personal information of a large number of users uniquely by the dedicated personal information server, the problem of the registration of each one and the problem of the external leakage of the enormous personal information are solved.

When a data broadcast signal is superimposed on a television broadcast, various information can be transmitted inexpensively over a very wide area (wide area). As a result, various information providing companies can transmit information.

However, since an individual user provides personal information to a commercial information providing company or a service company, problems such as privacy protection and the like may arise in the event of leakage of intense personal information. For this reason, it is necessary to protect the information of individual users.

In particular, when the personal information is maintained and managed by the response server itself, it is necessary to register the personal information with each increase in the number of response servers, which is troublesome and there is a fear that the personal information will leak out to the outside unexpectedly Thereby causing a problem of privacy protection.

In addition, registration of user personal information such as a name, an address, and a telephone number is indispensable in order to receive various online services including on-line shopping performed through a telephone line between the data broadcast receiving apparatus and the response server as described above .

However, these personal information may change. When I move a residence, my address and phone number change. You can also change your phone number without having to relocate. The name may be changed for reasons such as marriage. If the personal information already registered in the personal information server remains unchanged even though the personal information is changed, the user side can not receive the online service and the information providing company or service provider side does not establish the commercial level do. When the user's personal information is changed according to the principle of the beneficiary burden, the user must actively re-register (update) the new personal information with respect to the personal information server.

However, it is often the case that it becomes time to utilize the provision of online services to realize that it is indeed necessary to register for renewal. Since it is the stage where the renewal registration is not yet carried out, in reality, the online service can not be provided if necessary. In this case, it is difficult to say that the bidirectional data communication system functions organically.

Therefore, in order to organically function the bi-directional data communication system, a countermeasure that positively urges that the update registration should be performed if there is a change in personal information to the user periodically is considered.

An object of the present invention is to efficiently and surely manage user information to be recorded in such a personal information server to solve the above problems.

In order to solve such a problem, the present invention provides a method for controlling a mobile terminal, comprising the steps of decoding a data broadcast signal transmitted by a television broadcast or a telephone line, displaying information of the decoded television broadcast or data broadcast, The method comprising the steps of: providing user information to a server; and performing information management regarding registration, update, and confirmation of the user information to a personal information server.

A data broadcast decoder means for decoding a data broadcast signal transmitted by a television broadcast or a telephone line as an apparatus using this method, display means for displaying information of a television broadcast or data broadcast decoded by the data broadcast decoder means, A modem connected to the line, and user information management means for managing user information to be recorded on the personal information server via the modem, wherein the user provides the user information to the personal information server via the telephone line, And an information management means for managing information relating to the registration, update, and confirmation of the user information to the personal information server.

Thus, the protection, update, and registration of the user information can be reliably executed, and the adverse effect caused in the bidirectional communication can be prevented in advance.

In addition to the effect of eliminating the need to register personal information in each of the response servers by establishing an organization such as a personal information server that uniquely manages the maintenance and management of personal information, By providing the user information management means for registering, updating, and inquiring information of information in the bidirectional data communication apparatus itself, the registration, update and inquiry confirmation of the personal information is facilitated and the protection is further secured.

The step of receiving the user information may include transmitting the first information encrypted by the user to the response server via the telephone line, receiving the encrypted acknowledgment from the personal information server via the response server, The method comprising the steps of: receiving key information for decrypting the key information; confirming transmission of the first information by the key information; transmitting encrypted second information for supplementing the first information to the personal information server via the response server Wherein the personal information server transmits user information to the response server according to the second information and the response server supplies the information to a third party. will be.

Means for transmitting, by the user information management means, the first information encrypted by the user to the response server via the telephone line, means for receiving the encrypted acknowledgment from the personal information server via the response server, Means for receiving the key information for decrypting the acknowledgment, means for confirming transmission of the first information by the key information, means for transmitting the encrypted second information supplementing the first information to the personal information server And the personal information server transmits the user information to the response server according to the second information, and the response server supplies the third party with the information, thereby further enhancing the protection of the data . That is, the user can confirm that the order has been received. At the time of ordering, the information provider company or the service company can not store the personal information, so the user's personal information can be used only once as a response to the order, .

The step of displaying the user information may include a step of executing a connection inquiry of a telephone line in accordance with user information from a personal information server after a predetermined time after the telephone line is disconnected and a step of displaying completion of the procedure when the inquiry is executed The step of notifying that the procedure is not completed is provided. As a device using this method, in a system for easily performing user registration to a personal information server that manages personal information separately from an information providing company or a service company, and for protecting user information, the user information management means Means for executing connection inquiry of the telephone line according to the user information from the personal information server after a predetermined time after the telephone line is disconnected, displaying the completion of the procedure when the inquiry is executed, and displaying the completion of the procedure By providing the display means, the update of the data is ensured.

If the step of managing the user information is in agreement with the step of comparing the month-day data of the registered user information with the current date and time, or if there is a change in the user's personal information for a certain period thereafter, The method comprising the steps of: Means for comparing the date and time data of the user information registered by the user information management means with the current date and time; means for prompting for update registration if there is a change in the user's personal information during or after a certain period of time By having a means for displaying a message, the data update can be performed more efficiently and reliably. That is, even when the personal information of the user such as the name, the address, and the telephone number is changed, the message of the update registration request is displayed, so that the update registration is performed and the bidirectional data communication system can function organically.

Reference numeral 11 denotes a CPU (central processing unit) for controlling the entire system, reference numeral 12 denotes a ROM (Read Only Memory) which stores a program for its control, reference numeral 13 denotes a control A RAM (Random Access Memory) for storing a decoded data broadcast signal while supporting an operation, a reference numeral 14 is an input terminal of a television signal received by a reception antenna (not shown), a reference numeral 15 is an input Reference numeral 16 denotes a data broadcasting decoder unit for separating and decoding the data broadcasting signal superimposed on the vertical blanking period of the demodulated video signal, Reference numeral 17 denotes an image switching unit which switches between the video signal from the video signal receiving unit 15 and the data broadcasting signal from the RAM 13 and sends out the video signal, Control of the display state such as switching of the reception channel at the channel line local unit in the reception unit 15, division of the screen in the display unit 19 or scrolling of the data broadcasting signal, or control of the image switching unit 17 Reference numeral 20 denotes an operation input unit such as an operation panel or a remote controller capable of performing data input operation; 21 denotes an input interface; reference numeral 22 denotes an input interface; A modem 23 for performing bidirectional communication with the telephone line by converting the digital data into an analog voice signal level and a modem 23 for connecting each part from the CPU 11 and the ROM 12 to the modem 22 And a reference numeral 24 denotes an NCU (Network Control Unit) for connecting the modem 22 to the telephone line 30. Reference numeral 40 denotes a response server connected interactively (bidirectionally) with the NCU 24 of the bidirectional data communication apparatus 10 via the telephone line 30. [ Reference numeral 50 denotes a personal information server that is interactively connected to the NCU 24 and the response server 40 of the bidirectional data communication apparatus 10 via the telephone line 30. [

First, a general operation of reception of a data broadcasting program will be described. The video signal receiving unit 15 selects the television signal from the received television signal, and sends out the television signal of the receiving channel to the video switching unit 17 and to the data broadcasting decoder unit 16. The data broadcast decoder unit 16 separates and decodes the data broadcast signal superimposed on the vertical blanking period of the selected video signal, and sends it to the RAM 13 to temporarily store it. The display control section 18 controls the image switching section 17 to transmit either the video signal of the television broadcast from the video signal receiving section 15 or the data broadcast signal read out from the RAM 13 to the display section 19 do. The display control section 18 also controls whether the display form on the display section 19 is a full screen or two screens and displays character data on the lower or upper side of the full screen in a telop- . The control executed by the display control unit 18 is determined by an input command from the operation input unit 20. [

When the contents of the program relating to the data broadcast are, for example, a quiz program of a viewer participation, a variety program or a questionnaire survey, the user executes an operation of selecting one of preset answers and sends an automatic dial command, Dials the response to the response server 40 via the modem 22, the NCU 24 and the telephone line 30 and provides the answer information to the response server 40. The response server 40 processes the information as necessary and communicates the result to the broadcasting station via the telephone line.

Next, the operation when the bidirectional data communication apparatus 10 is connected to the response server 40 and the personal information server 50 via the telephone line 30 to place a product order will be described with reference to Figs. 2, 3, 4 .

FIG. 3 shows the number of data at this time, FIG. 4 shows the contents of the data, and FIG. 5 shows a time series of data reception.

First, the operation of the user will be described.

The user terminal is in a state of storing the key information for decrypting the password in the personal information server 50 which keeps the personal information collectively for protecting the user (step S11).

The article information is provided via the television station 60 or the telephone line, and the broadcast is received and displayed (step S12). By confirming the order, the order confirmation data 1 (consisting of terminal ID and user ID) of Fig. 4 is transmitted to the response server 40 (step S13). At this stage, it is not necessary to transmit specific order information. The response server 40 serves as an intermediary between a user and a sales company that actually sells the goods, various service companies, information providers, television stations, broadcasting stations that provide information via telephone lines, and the like.

Once the telephone line is disconnected, it is waited for reception from the response server 40 (step S14). If the encryption use information can not be received at the predetermined time, the process is terminated (steps S16 and S17). When the encrypted user information is received (step S15), the encrypted user information is decrypted using the received decryption key information (step S18), and the user information is displayed (step S19). As a result, the user can confirm that the order has been received.

A specific request is made to the response server 40 and an order is placed by transmitting the order confirmation data 2 (terminal ID, user ID, password, order article information) (step S20). Thus, the order processing is completed (step S21).

Next, the operation of the response server 40 will be described.

The response server 40 is in a state capable of receiving a connection from the terminal of the individual user via the telephone line (step S31). Confirms the connection from the individual user, receives the order confirmation data 1 (step S32), extracts the terminal ID from the personal information, and transmits it to the personal information server 50 (step S33).

(Step S34). If it can not be received within the predetermined time, the line is disconnected (step S36, step S37).

When the personal information server 50 receives the encrypted user information (composed of the service company code, terminal ID, user ID, address of the encrypted individual, name, etc.) (step S38), it transmits it to the user. Upon receipt of the order confirmation data from the user (step S39), the terminal ID or the product data (including the terminal ID, the user ID, the encrypted password, and the order article information) in the encrypted state is extracted and transmitted to the personal information server 50 (Step S40). (Step S41). If it can not be received within a predetermined time, the processing is completed (steps S43 and S44).

When the personal information server 50 receives the user information (name, telephone number, address, etc.), it transmits this as order information to an article sales company or the like (step S45) and completes the order processing (step S46). The article sales company 70 or the like receives this and sends the article or the like to the individual user, and collects the money from the user.

It is also possible that the credit card number is provided as user information and the payment is completed.

Here, since the response server can not always say that the encryption method is not always the same even if the order confirmation data 1 and 2 and the user information are combined, it is possible to confirm that the user having the specific address and the name purchased the specific article by one order However, in the next order, at the stage of receiving the order confirmation data 1 and 2, it is not possible to know which user has ordered and thus the user can be protected.

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 the response server 40 is waiting for reception (step S52).

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

Upon receiving the terminal ID data from the response server 40 (step S53), the user information is retrieved from the database provided by the personal information server 50 (step S54) and is encrypted (step S55) The service company code, the terminal ID, the user ID, the address of the encrypted individual, and the name) to the response server 40 (step S56).

This is transmitted to the user via the response server 40, whereby an order confirmation to the user is made. When a specific order from the user is received as a terminal ID and product data via the response server (step S57) (Step S58), and transmits it to the response server 40 (step S59). This completes the operation of the one-order personal information server 50.

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

Although the personal information is provided to the response server 40 twice, the method of providing the personal information is not limited to this embodiment. Encrypting more information at the time of the first data transmission (order confirmation data 1) does not hinder.

(Example 2)

Since the electrical configuration of the bidirectional data communication apparatus of the second embodiment is the same as that of the first embodiment shown in Fig. 2, the description of the configuration of Fig. 2 is omitted. The operation will be described using the flowcharts shown in Figs. 6 and 7. Fig.

First, a general operation of reception of a data broadcasting program will be described. The video signal receiving unit 15 of Fig. 2 selects the television signal from the received television signal, sends out the television signal of the receiving channel to the video switching unit 17, and sends it to the data broadcasting decoder unit 16. The data broadcast decoder unit 16 separates and decodes the data broadcast signal superimposed on the vertical blanking period of the selected video signal, and sends it to the RAM 13 to temporarily store it. The display control section 18 controls the video signal switching section 17 to switch either one of the video signal of the television broadcast from the video signal receiving section 15 and the data broadcast signal read out from the RAM 13 to the display section 19 . The display control unit 18 controls whether the display form of the display unit 19 is a full screen or two screens and simultaneously scrolls and displays character data on the lower or upper side of the full screen . The control executed by the display control unit 18 is determined by an input command from the operation input unit 20. [

When the contents of the program relating to the data broadcast are, for example, a quiz program of a viewer participation, a variety program or a questionnaire survey, the user performs an operation of selecting one of preset answers and sends an automatic dial command, (NC) 24, and the telephone line 30 to the response server 40, and provides the response information to the response server 40. [ The response server 40 processes the information as necessary and communicates the result to the broadcasting station via the telephone line.

Next, the operation when the bidirectional data communication apparatus 10 is connected to the personal information server 50 via the telephone line 30 and registration is executed will be described.

The operation of the individual user will be described in accordance with the flowchart of Fig.

The user inputs user information to the personal information server 50 via the user telephone line (step S111), and issues a connection request to the personal information server 50 (step S112).

When the connection is confirmed (step S113) and the connection can not be made, the connection request is executed again (step S112).

As a result, the device ID and the user information of the data broadcast receiving apparatus are transmitted to the server (step S114), and the telephone line is once disconnected (step S115). Then, after a predetermined time (step S116), the personal information server performs connection of the telephone line in accordance with the user information (step S117), and transmits the device ID to the server (step S119) And is confirmed from the server (step S120). When the inquiry is confirmed, registration completion is displayed (step S121). When the connection is not established within a predetermined time (step S118), unregistered is displayed (step S122).

Next, the operation of the personal information server according to the flowchart of Fig. 7 will be described.

The personal information server 50 is in a state capable of receiving a connection from the terminal of the individual user through the telephone line (step S1101). A connection from the individual user is confirmed (step S1102), and the device ID and user information are thereby received by the server (step S1003), and the device ID is recorded (step S1004). Further, the telephone number is subtracted from the user information (step S11O5), and the telephone best is cut once (step S11O6). Then, after a predetermined time, the personal information server 50 issues a telephone line connection request in accordance with the personal user information (step S11O7), confirms the connection (step S11O8), receives the device ID S119), inquiry is executed (step S1111), confirmation is transmitted to the personal terminal (step S1112), and registration is completed. If the inquiry of the device ID does not coincide, it sends an inconsistency to the personal terminal (step S1113). This makes it possible for the personal information server or the user to disconnect the telephone line.

When the connection is not possible (step S11O), the connection request is returned (step S11O7).

(Example 3)

Next, the registration method will be described with reference to Figs. 8, 9 and 10. Fig.

The operation of the individual user will be described in accordance with the flowchart of Fig. The user inputs user information to the personal information server 50 via the user's phone line.

When the user accesses the personal information server 50, the user waits until data is transmitted from the server 50 (step S131) and receives a list of the prefecture name, city name, and town name (Step S133), the user can select the wise name, the name and the final name of the user.

Further, by pressing the enter key (step S135), the selected information is transmitted to the server 50, and the data of the more detailed address is transmitted from the server 50. [

By repeatedly transmitting this operation, the address can be determined and transmitted to the server 50.

The operation of the personal information server according to the flowchart of FIG. 9 will be described.

The server 50 provides the address information to the individual user via the telephone line and waits for transmission from the individual user (step S1201). Upon receiving the user's selection, the server 50 searches the local database DB (step S1203) More detailed address information is transmitted to the personal terminal (step S1204).

When this operation is repeated and the address is confirmed (step S1202), the address information is registered in the user database (step S1205).

The address database may be provided by the terminal itself.

Here, FIG. 10 shows a method of selecting a user, and the address is confirmed by selecting a selection screen as shown in FIG. 10B with a cursor.

The address database has a hierarchical structure as shown in FIG. 11, and a list of more detailed addresses is selected by the user's selection.

(Example 4)

Next, the operation when the bidirectional data communication apparatus 10 is connected to the personal information server 50 via the telephone line 30 to update personal data will be described.

The operation of the individual user will be described in accordance with the flowchart of Fig.

When the user changes the user information such as the telephone number, the device ID and the address of the bidirectional data communication device 10 and completes the procedure, the change flag is not set (step S141). If not, It is in a state waiting for a connection from the information server 50 (step S142).

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

(Step S143), transmits the changed user information to the personal information server 50 via the telephone line to the personal information server 50, and completes the procedure (steps S145 and 147).

The specific flow of this procedure is as described in the above embodiment.

If the connection can not be established, it is found that the change registration to the personal information server is not completed and the procedure is completed (step S146).

Next, the operation of the personal information server according to the flowchart of Fig. 13 will be described.

The personal information server 50 executes a connection request from the terminal of the individual user via the telephone line (step S1302), confirms the connection (step S1303), thereby receiving the device ID and the user information (step S1304 ), And the device information such as the device ID of the database of the personal information server (step S1305).

If the query is not possible, the change flag is set in the database of the personal information server and the connection is terminated.

When the user information is not 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 the same as that of the flowchart of Fig. 6 described in the second embodiment. In the step S131 of Fig. 8, the registration completion display is performed and the change flag is not set. The operation of the personal information server at the time of re-registration is the same as that of the flowchart of Fig. 9, and is registered in the database (step S1205) in Fig. 9 and the change flag of the user database is not set.

If the query is not possible, the change flag is set in the database of the personal information server and the connection is terminated.

Also, unlike the case where the change of the user information is started by the connection request of the personal information server 50, the personal information such as the device ID, the address, and the telephone number can be periodically changed by the user's regular connection request .

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

(Example 5)

14 is a block diagram showing an electrical configuration of the bidirectional data communication apparatus according to the fifth embodiment.

In Fig. 14, those having the same functions as those of the first, second, third and fourth embodiments are denoted by the same reference numerals. Description of the same functional configuration will be omitted.

Reference numeral 40 denotes a response server that is interactively (bidirectionally) connected to the NCU 24 of the bidirectional data communication apparatus 10 via the telephone line 30, and reference numeral 50 denotes a response server connected to the telephone line 30 A personal information server interactively (bidirectionally) connected to the NCU 24 and the response server 40 of the bidirectional data communication apparatus 10 via the network 20, and a television broadcast station 60. Although not shown, there are a plurality of response servers 40, and each of the response servers 40 is connected to the personal information server 50 via the telephone line 30. [ Each response server 40 and the personal information server 50 are connected to the television station 60 via the telephone line 30. [

First, the operation of initial registration of user personal information will be described. Typically, when the bidirectional data communication device 10 is purchased or when an online service contract is entered, initial registration of user personal information to the personal information server 50 is executed. This initial registration is executed via the telephone line 30. [ That is, the user operates the operation input unit 20 to display a menu of personal information registration on the display unit 19, and transmits a user registration request with the terminal ID via the modem 22 and the telephone line 30 To the personal information server 50. The terminal ID is stored in the ROM 12. The personal information server 50 that receives this information downloads the registration program to the bidirectional data communication device 10 via the telephone line 30. [ The program is stored in the RAM 13. The user inputs personal information such as name, address, telephone number, date of birth, sex, etc. by key operation. The personal information is sent to the personal information server 50 via the telephone line 30 and stored in the hard disk. The birth date in accordance with the birth date of the personal information is registered in the RAM 13 of the bidirectional data communication apparatus 10. [ Next, the personal information server 50 automatically dials the registered phone number to confirm registration completion, and the personal information server 50 transmits the user ID. The bidirectional data communication device 10 then transmits the received user ID And registers it in the RAM 13 and then erases the registered program. It is also possible that the registration program is stored in the memory of the terminal in advance and the personal information is input from the terminal without downloading from the personal information server, and then the registration processing is performed on the personal information server via the telephone line.

As described above, in the personal information server 50, user personal information such as a name, an address, and a telephone number is registered along with a user ID, and the user 13 is registered in the RAM 13 of the bidirectional data communication apparatus 10 as a predetermined month Birthday is registered.

Next, a general operation of reception of the data broadcasting program will be described. The video signal receiving unit 15 selects the television signal from the received television signal, and sends out the television signal of the receiving channel to the video switching unit 17 and to the data broadcasting decoder unit 16. The data broadcasting decoder unit 16 separates and decodes the data broadcasting signal superimposed on the vertical blanking period of the selected video signal, and sends it to the RAM 13 to temporarily store it. The display control section 18 controls the image switching section 17 to transmit either the video signal of the television broadcast from the video signal receiving section 15 or the data broadcast signal read out from the RAM 13 to the display section 19 do. The display control unit 18 controls whether the display form of the display unit 19 is a full screen or two screens and simultaneously scrolls and displays character data on the lower or upper side of the full screen . The control executed by the display control unit 18 is determined by an input command from the operation input unit 20. [

When the contents of the program relating to the data broadcast are, for example, a quiz program of a viewer participation, a variety program or a questionnaire survey, the user performs an operation of selecting one of preset answers, And automatically answers the response server 40 via the modem 22, the NCU 24, and the telephone line 30, and provides the answer information to the response server 40. The response server 40 carries out processing on the information as required and communicates the result to the broadcasting station 60 via the telephone line.

Next, the operation when online shopping is performed by viewing the contents of the television broadcast or the communication information from the response server will be briefly described. The transmitted product information is displayed on the display unit 19. [ When order confirmation is instructed by the operation of the operation input unit 20, the order confirmation data (terminal ID, user ID, password, order product information) is transmitted to the response server 40 via the telephone line 30, Complete. The response server 40 transmits the terminal ID to the personal information server 50 and receives the user's personal information (name, address, telephone number, etc.) from the personal information server 50, Information is transmitted and the order processing is completed. The merchandise sales company sends the order goods to the corresponding user according to the user's personal information and collects the payment from the user.

Next, the operation of the birthday message display will be described. As described above, birthday data of the user is registered in the RAM 13 of the bidirectional data communication apparatus 10, and personal information of the user such as name, address, and telephone number is stored in the personal information server 50 It is registered. In the television broadcasting station 60, the birthday message is always transmitted by broadcast waves. This birthday message includes a message informing that the birthday has been made and an invitation message for renewal registration due to the change of the user's personal information. For example, "Happy birthday. If you change your name, address, phone number, etc., please register it. " The birthday message overlaps with the vertical blanking period of the broadcast wave. This birthday message is always received by the bidirectional data communication device 10, but is not displayed until it is a birthday.

As shown in the flowchart of Fig. 15, when the power of the bidirectional data communication apparatus 10 is turned ON, the CPU 11 determines whether the present date / time corresponding to the built-in timer has reached the birth date registered in the RAM 13 (Step S151). If the date of birth is not reached, the display of the birthday message is prohibited (step S155). However, when the birthday is reached, (Step S152). If it is within one month, the display unit 19 displays the birthday message decoded by the data broadcasting decoder unit 16 (step S153). As a result, the birthday message is displayed every time the power of the bidirectional data communication device 10 is turned on for one month from the birthday. (Step S154), and prohibits (stops) the display of the birthday message (step S155). The user is prompted to judge whether or not the personal information such as the current name, address and telephone number has already been changed in the name, address and telephone number registered in the personal information server 50, It is urged to renew registration. When it exceeds one month from the birthday, the display of the birthday message is not executed because a sufficient message is already delivered to the user (step S155).

When the personal information is changed, the user performs update registration of the personal information with respect to the personal information server 50. [ Thereby, the online service can be continuously provided.

By the way, it is troublesome for the user to display the birthday message over one month from the birthday. This is solved by the operation shown in the flowchart of Fig. 16A. When the user desires not to display the birthday message, the user operates the erase key in the operation input unit 20 (remote controller). CPU (11) is the erase key is operated that resets the display flag F ₁ when it is determined whether or not (step S1401), the operation (step S1402). And, display of birthday message even when there further step S152a in the 15 flow diagram of, and runs the display of birthday message (step S153), the resets the display flag F ₁ as long as when there is set, the display flag F ₁ (Step S155).

When the display flag F ₁ is reset, the birthday message is not displayed when the birthday of the next year comes. So, for example, from a birthday, as it is determined whether or not for 11 months has elapsed (step S1501), when it is passed to return the display flag F ₁ to the set state (step S1502) shown in FIG. 16B. Then, the determination in step S152a is YES, and the birthday message is displayed again.

(Example 6)

The contents of the birthday message in the case of the fifth embodiment are as follows: " If there is a change in name, address, telephone number, etc., In this regard, it is considered to display personal information such as a specific name, address, and telephone number already registered. In other words, as a birthday message, for example, "Happy birthday. Your registered name, address, phone number ... , ... , ... Is there no change? If you have any changes, please register. " The fifth embodiment displays the birthday message with such content. The birthday message including such personal information is transmitted from the personal information server 50, not from the broadcasting station 60. Therefore, the message transmission is transmitted only when there is a request, not always.

The operation will be described with reference to the flowchart of Fig. When the power of the bidirectional data communication apparatus 10 is turned on, the CPU 11 determines whether or not the current date and time corresponding to the built-in timer has reached the birthday registered in the RAM 13 (step S1601) When the birthday is reached, it is determined whether or not it is within one month from the birthday (step S1602). If the birthday is reached, And performs automatic dialing to the personal information server 50 via the Internet. At this time, the terminal ID is transmitted and a birthday message transmission request is executed (step S1603). Then, it waits for reception from the personal information server 50 (step S1604). When there is a birthday message transmission request from the bidirectional data communication device 10, the personal information server 50 transmits a birthday message including personal information to the bidirectional data communication device 10 having the requested terminal ID. The bidirectional data communication apparatus 10 stores the birthday message including the received personal information in the RAM 13 (step S1605), and displays the birthday message on the display unit 19 (step S1606). As a result, the birthday message is displayed every time the power of the bidirectional data communication device 10 is turned on for one month from the birthday. (Step S1607), the display of the birthday message is stopped (step S1608), and the birthday message is deleted from the RAM 13 (step S1609). The user can view the birthday message specifically including the personal information such as the name, address, and telephone number, and display the personal information such as the current name, address, and telephone number and the name, address, telephone number The comparison of personal information such as the number is performed very clearly, and when it is strongly urged to judge whether or not it has been changed, the user is urged to renew the information. When one month has passed since the birthday, a message transmission request to the personal information server 50 is not executed.

When it is desired to prohibit the display of the birthday message for one month from the birthday after confirming the birthday message, it is preferable to operate the erase key in the same manner as in Fig.

(Example 7)

The seventh embodiment is a case where the response server 40 receives the birthday message instead of the personal information server 50. [ In this case, the birthday message does not include specific personal information such as name, address, and telephone number. If you change your name, address, phone number, etc., please register for renewal. "

In the flowchart shown in Fig. 17, it is possible to replace "personal information server" with "response server" in step S1603 and replace it with a simple "birthday message" instead of "birthday message containing personal information" in step S1605.

(Example 8)

The eighth embodiment occurs inside the bidirectional data communication apparatus 10 instead of receiving the birthday message from the outside. That is, the birthday message is written in advance in the ROM 12, and the birthday message is read from the ROM 12 when the current date and time becomes the birthday (and for one month thereafter) And displays it on the display section 19. In the case of this embodiment, a large memory capacity is required for the ROM 12, but control of message display becomes very simple.

(Example 9)

In each of the fifth to eighth embodiments, the birthday data is registered in the RAM 13 by the operation of the operation input unit 20. [ This is for the bidirectional data communication apparatus 10 to determine whether or not the current date and time is a birthday. There is an opinion that it is natural to register the birthday in the bidirectional data communication device 10 because the birthday is the birthday of the user of the bidirectional data communication device 10. [ However, if the power is turned off or the outlet is disconnected, the birthday data is erased in the RAM 13. In this case, it is necessary to re-register the birthday, which can make the user cumbersome and forgetful.

Therefore, it is also suggested that the birthday data is registered in the personal information server 50 and the personal information server 50 manages whether or not it is a birthday. The following is the ninth embodiment described below.

The personal information server 50 registers the user's personal information such as the user's date of birth (birthday) and terminal ID in addition to the name, address, and telephone number. The CPU of the personal information server 50 determines whether or not the current date and time corresponding to the built-in timer has reached the registered birthday, and when it reaches the broadcast date, sends the corresponding terminal ID and message transmission command to the broadcasting station 60 . The broadcasting station 60 transmits the received terminal ID and the birthday message on the broadcasting wave. This processing is basically carried out over one month from the date of birth.

The operation will be described with reference to the flowchart of Fig. The CPU 11 of the bidirectional data communication apparatus 10 determines whether or not the terminal ID has been received from the broadcasting station 60 at the power-on time (step S1701). When receiving the terminal ID, (Step S1702). When the two terminal IDs match as a result of comparison (YES in step S1703), the birthday message received by the broadcasting station 60 is displayed on the display unit 19 (step S1704). The birthday message displayed at this time is usual, for example, "Happy Birthday". If you have changed your name, address, phone number, etc., please renew your registration. "

(Example 10)

A method of displaying a birthday message including personal information as a birthday message in a format in which birthday data is not registered in the RAM 13 of the bidirectional data communication device 10 is also considered. This is Example 9. The acquisition of the birthday message including the personal information is executed by accessing the personal information server 50. [ That is, steps S1603 to S1609 in Fig. 17 are executed after steps S1701 to S1703 in Fig.

The CPU 11 of the bidirectional data communication apparatus 10 determines whether or not the terminal ID is received from the broadcasting station 60 at the power-on time (step S1701). When receiving the terminal ID, (Step S1702). As a result of the comparison, if the two terminal IDs match (YES in step S1703), automatic dialing is performed on the personal information server 50 via the telephone line 30. [ At this time, a birthday message transmission request is issued together with the terminal ID as shown in Fig. 17 (step S1603). Then, it waits for reception from the personal information server 50 (step S1604). When the birthday message transmission request is issued from the bidirectional data communication apparatus 10, the personal information server 50 transmits a birthday message including personal information such as a name, an address, and a telephone number to the bidirectional data communication apparatus 10 . The bidirectional data communication apparatus 10 stores the birthday message including the received personal information in the RAM 13 (step S1605), and displays the birthday message on the display unit 19 (step S1606). As a result, the birthday message is displayed every time the power of the bidirectional data communication apparatus 10 is turned on for one month from the birthday. (Step S1607), the display of the birthday message is stopped (step S1608), and the birthday message is deleted from the RAM 13 (step S1609).

(Example 11)

In the ninth and tenth embodiments, after the user confirms the birthday message including the birthday message or the personal information, the user is solved from the troubles of message display for one month from the birthday.

As in the case of Fig. 16, the user operates the erase key on the operation input unit 20 (remote controller) when trying not to execute the display of the birthday message. The CPU (11) as shown in Figure 16A is the erase key is operated that resets the display flag F ₁ when it is determined whether or not (step S1401), the operation (step S1402). Further, the birthday message is displayed in the time to be added to step S1703a in the flow chart of Figure 18, and runs the display of birthday message (step S1704), the display flag F ₁ is reset as long as the time it is set, the display flag F ₁ (Step S1706). If the display flag F ₁ is reset, the birthday message is not displayed when the birthday of the next year returns.

So, for example, from a birthday, as it is determined whether or not for 11 months has elapsed (step S1501), when it is passed to return the display flag F ₁ to the set state (step S1502) shown in FIG. 16B. In this case, the determination in step S1703a of FIG. 18 is YES, and the birthday message is displayed again.

It is contemplated that the transmission of the birthday message from the broadcasting station 60 is not executed when the erasing key is operated on the operation input unit 20 as another method. That is, when the erasing key is operated, the bidirectional data communication apparatus 10 automatically dials the personal information server 50 and transmits an erase signal together with the terminal ID. The personal information server 50 receiving the erasure signal resets the display flag F ₁ as personal information of the corresponding terminal ID. When the display flag F ₁ is reset, the CPU of the personal information server 50 does not transmit the terminal ID to the broadcasting station 60 even when the current date and time reaches the birthday. Therefore, in the broadcast station 60, the transmission of the terminal ID and the birthday message is not performed. For example, when 11 months have elapsed since the birthday, the display flag F ₁ is returned to the set state, and when the next birthday returns, the birthday message is sent again.

In the fifth to eleventh embodiments, the birthday is typically described as a predetermined monthday to be compared with the current date and time. However, the present invention is not limited to this, and the user may register the desired monthday.

In Examples 5 to 11 above, an update registration request message was displayed with an opportunity of once a year. On the other hand, the embodiment described below increases the opportunity for the renewal registration request by dividing one year into four seasons and displaying an update registration request message every season.

The display flag can also be maintained in the personal information server.

(Example 12)

_Four dates of T ₁ , T ₂ , T ₃ and T ₄ are set as the date of season change, and four types of seasonal messages M ₁ , M ₂ , M ₃ and M ₄ are set corresponding to each of these dates do. Specifically, here, for example, T ₁ is December 31, T ₂ is March 31, T ₃ is June 30, and T ₄ is September 30 as an example. As a seasonal message M ₁ , for example, "Congratulations on the New Year. Thank you very much for coming this year. If you change your name, address, phone number, etc., please register the renewal. "As seasonal message M ₂ , for example," It became very warm. The cherry blossoms are beautiful. And, … ... (Alumni) ... ... As a seasonal message M ₃ , for example, "It is very hot this summer. And ... ... (Alumni) ... ... , And as seasonal message M ₄ , for example, " the autumn is becoming more and more day by day. Be careful not to catch a cold, and ... ... (Alumni) ... ... &Quot; (Alumni) section, "Please update your name, address, and phone number if you have any changes."

In the bidirectional data communication apparatus 10, the CPU 11 executes the management of the season flag F ₂ in accordance with the built-in timer. That is, the reset of season flag F ₂ (Step S1802) If the season is determined whether or not the date T ₁ changes (step S1801), so as shown in the flow chart of Figure 6, the seasons change in the following date is determined whether or not a T ₂ (step S1803), when it is determined whether or not to reset the season flag F ₂ (step S1804), the date the seasons change to the next T ₃ (step S1805) , when it is to reset the season flag F ₂ when determining whether to reset the season flag F ₂ (step S1806), the date the seasons change to the next T ₄ (step S1807), that is (step S1808).

A date on which the season changes in the broadcasting station 60 is selected and a seasonal message according to the current season is selected from among the four kinds of seasonal messages M _{1 to} M ₄ and is transmitted on a broadcast wave at all times.

When the bidirectional data communication apparatus 10 enters the reception mode of the data broadcasting service, the operation of the flowchart of Fig. 20 is executed. Receiving a seasonal message from the broadcasting station 60 (step S1901), the season message received on the display section 19. When there season flag F ₂ is determined whether or not is reset (step S1902), Li is set displayed (step S1903), the season flag F ₂ is set to indicate that there was a display (step S1904). As a result, a message including the seasonal greetings and a request for renewal registration is displayed. Once the message of the display is running, since the season flag F ₂ is set to, is in the determination of the step S62 NO in the message display is not executed.

Specifically, it is as follows. For example, on December 31 (T ₁ ), the season flag F ₂ is reset. If we receive the data broadcasting service on the next day, January 1, we would like to congratulate the new year of seasonal message M ₁ . Thank you very much for coming this year. If you change your name, address, phone number, etc., please register and renew. " Next, even if the data broadcasting service is received on January 2, since the season flag F ₂ is set, the display of the seasonal message M ₁ is not executed. Next, on March 31 (T ₂ ), the season flag F ₂ is reset again. When the data broadcasting service is received thereafter, the season message M ₂ is displayed. Even if the same service is received thereafter, The display of M ₂ is not executed. Hereinafter, the same is displayed, and the display of the update registration prompt message four times in a year is executed, and the opportunity of the update registration registration is increased.

(Example 13)

The thirteenth embodiment also displays user personal information such as a name, an address, and a telephone number registered in the personal information server 50. [ Receiving a seasonal message from the broadcasting station 60, as shown in the flow chart of FIG. 21 (Step S2001), the season flag F ₂ is when it is reset is determined whether or not (step S2002), in that the reset phone Performs automatic dialing to the personal information server 50 via the line 30, transmits the terminal ID, and executes transmission request of user personal information (step S2003). Then, it waits for reception from the personal information server 50 (step S2004). The personal information server 50 transmits the registered user personal information to the bidirectional data communication apparatus 10 having the terminal ID that is registered in accordance with the request from the bidirectional data communication apparatus 10. [ The bidirectional data communication apparatus 10 displays the seasonal message received by the broadcast station 60 and the user personal information received from the personal information server 50 on the display unit 19 (step S2005) the season flag F ₂ is set (step S2006). As a result, a message consisting of specific personal information such as the seasonal greetings, urgent renewal registration, and name, address, and telephone number is displayed. Once the display of the message is executed, the season flag F ₂ is set, and therefore the determination in step S72 is NO, and the message is not displayed.

(Example 14)

In the fourteenth embodiment, the determination of the season flag F ₂ is executed by the response server, and the response message is transmitted from the response server. 22 showing the operation of the bidirectional data communication apparatus 10 side and the operation of the response server 40 side will be described with reference to the flowchart of FIG.

When the interactive data communication apparatus 10 uses the online service for the response server 40 via the telephone line 30, the access to the response server 40 is performed as shown in Fig. 22 (step S2101) , that is when the season and transmits the flags F ₂ and the terminal ID to the response server 40 (step S2102), the response server 40 is in the season flag F ₂ that has been transmitted as shown in Figure 23 in, it has a set of (Name, address, telephone number, and the like) (step S2202) and accesses the personal information server 50 when it is reset (step S2201) (Step S2203) to the bidirectional data communication apparatus 10 having the terminal ID that has received the message composed of the specific personal information such as the name, address, and telephone number (step S2203) process Is executed (step S2204). On the side of the bidirectional data communication apparatus 10, a message consisting of specific personal information such as seasonal greetings, urgent registration request and name, address and telephone number transmitted from the response server 40 is received (step S2103) the season flag F ₂ is set to indicate that display the message (step S2104), shown in (step S2105). Hereinafter, normal online service processing is executed (step S2106).

Once step S2103 the message is executed, since the season flag F ₂ is set, it may perform access the online service until the next time the season flag F ₂ is reset by the process of Figure 19 the side of response server 40. Fig. The determination in step S2201 of step S2201 is NO, and the processes in steps S2202 and S2203 are skipped and the process proceeds to the normal online service process (step S2204).

(Example 15)

Embodiment 15 In Embodiment 14, transmission and display of user personal information are omitted. That is, the user information acquisition processing in step S2202 of Fig. 23 is omitted. In step S2203, a message consisting of seasonal greetings and a request for update registration is transmitted to the bidirectional data communication device 10. [ The object of reception and display in steps S2103 and S2104 in Fig. 22 is a message composed of seasonal greetings and a request for update registration.

In the twelfth to fifteenth embodiments, different seasonal messages are prepared each time the four seasons change, but a common message may be used instead. For example, "Are there any differences?" It is also possible to divide one year into four, or two, or six, or twelve. The greater the number of divisions, the more opportunities for renewal registration can be given. The date on which the seasons of T ₁ , T ₂ , T ₃ and T ₄ in FIG. 19 are changed may be a common fixed value in all the bidirectional data communication apparatuses 10, It is likely to cause disordered access attempts, in other words, congestion of the line. Therefore, when the terminal ID is registered in the manufacturing process (before shipment) of the bidirectional data communication apparatus 10, the date on which the seasons change for each model or lot is slightly shifted and registered. Then, the timing of the update registration processing is dispersed, and the processing is smoothly executed as a whole.

As is apparent from the above-described embodiments, the present invention can securely perform protection, update, and registration of user information, and prevent adverse effects caused in bidirectional communication. Particularly, In addition to the effect of eliminating the need to register personal information in each of the response servers by establishing an organization called a personal information server to be executed, user information management means for registering, updating, and inquiring personal information of the personal information server By providing the bi-directional data communication device itself, registration, renewal, and inquiry confirmation of the personal information can be facilitated, and protection can be further ensured.

As described above, according to the present invention, it is possible to increase the confidentiality of the management of personal information in bidirectional data communication, and it is possible for the user to display the user's personal information once when ordering the goods, It is possible to confirm whether or not the personal information is correct or not accurately, whether or not the order has been changed correctly, and it is possible to maintain the accuracy of the user personal information, and the effect is to obtain the indispensable effect for the user.

In addition, according to the present invention, personal information can be managed over a long period of time, and the effect is an indispensable effect in bidirectional substitution.

According to the present invention, even when the user's personal information such as a name, an address, and a telephone number is changed, the update registration request message is displayed, so that update registration can be performed to organically function the bi-directional data system.
