Description: The present invention relates to a technique pertaining to an interactive television capable of selecting interactive TV programs in which a viewer can participate and, more particularly, to a television system for providing application services using the interactive TV set. In the field of television broadcasting in which radio waves are broadcast from broadcasting stations, television programs are selectively received by television receivers capable of receiving the broadcast radio waves, and television pictures of the selected television programs are displayed, teletext is performed by using areas between vertical retrace line intervals of television video signals. In this teletext, a large number of programs are multiplexed on broadcast radio waves and transmitted by the radio waves. On the receiver side, necessary programs are selectively received, converted into television picture signals, and displayed. By the use of the technology of this teletext, it is possible to provide viewers with an arbitrary large number of text programs or programs containing moving pictures, in addition to regular television programs on broadcasting. Unfortunately, the present television programs now on broadcasting one-sidedly provides information from broadcasting stations to viewers. For example a viewer cannot selectively display supplementary information of an article which he or she desires from a plurality of articles introduced in a television program. It is not possible to call out to viewers in a television program, totalize response from the viewers in real time, or reflect the result of totalization on the television program, either.

Figure 1 schematically shows the arrangement of an interactive television system constructed of a plurality of interactive televisions and a response server. Each of interactive televisions 1-1 to 1-n has a function, as a television receiver, of receiving broadcast radio waves transmitted from a broadcasting station 2 and displaying a television program assigned to a selected channel, a function of separating an interactive television program, which is multiplexed on a regular television program by using a predetermined range of broadcast radio waves, from the broadcast radio waves, and providing the Interactive television program, and a function of transmitting to the server a response from a viewer to the interactive television program. These interactive televisions 1-1 to 1-n can be connected to the response server 3 via a public communication network 4. The response server 3 comprises a plurality of local response servers 5-1 to 5-m to which interactive televisions in previously allocated predetermined areas are connected, and a center response server 6 for managing these local response servers. Note that the local response server and the center response server can be regarded as one response server from the interactive televisions 1-1 to 1-n. In the following description, these servers are collectively called the response server 3 if it is unnecessary to distinguish between them. The broadcasting station 2 and an IP/SP (information provider or service provider) company server 7 are connected to the response server 3 via a wide area communication network such as a WAN. Both the broadcasting station 2 and the IP/SP company server 7 connect to the response server 3 to receive data such as the result of totalization from the response server 3. The IP/SP company server 7 is managed by an information provider who wants to use processed data, such as the totalization result, acquired by the response server 3. FIG. 2 shows the software configurations of the interactive televisions 1 and the response server 3. Each of the interactive televisions 1-1 to 1-n includes a television program control unit 8 and a communication control unit 9 as main constituent elements for providing interactive television programs. The television program control unit 8 controls the progress of an interactive television program transmitted by a multiplexed broadcasting system from the broadcasting station 2. The communication control unit 9 controls communication lines to other nodes, including the response server 3, via the public communication network 4. FIG. 3 shows the internal structure of the interactive television 1. This interactive television 1 receives broadcast radio waves from a receiving antenna 21 and sends the received radio waves to a tuner 22. A channel selecting and response identification circuit 23 switches channels of the tuner 22. Instructions to the channel tuning and response identification circuit 23 are sent from a remote control switch 24. If a signal from the remote control switch 24 is a channel tuning signal, the channel tuning and response identification circuit 23 inputs the signal to the tuner 22. If a response to an interactive television program from a viewer is sent from the remote control switch 24, the channel tuning and response identification circuit 23 inputs the response to the television program control unit 8. A signal processing circuit 25 separates the signal supplied from the tuner 22 into a video signal and an audio signal. The signal processing circuit 25 inputs the video signal to a picture tube 26 for displaying pictures and the audio signal to an audio circuit 27 for outputting sounds. The television program control unit 8 progresses an interactive television program supplied from the tuner 22 by using program composition information (including a still or moving picture, audio information, image control information, and a script) of the program. By executing a program unit contained in the script, a video signal of the interactive television program is input to the picture tube, and an audio signal of the program is input to a loudspeaker 28. A whole bit stream (excluding partial control information) for displaying an interactive television program is called a script. Therefore, the script contains a header, a form, a resource, and the program portion. With respect to an item displayed in an interactive television program to prompt a viewer to input a response, the viewer inputs a response by using the remote control switch 24. The television program control unit 8 receives the viewer's response from the channel tuning and response identification circuit 23 and forms response data by adding to the response the television program ID of the television program and the television ID of the interactive television. Television program IDs are uniquely assigned to television programs provided by the interactive television. Television IDs are uniquely assigned to the interactive televisions 1-1 to 1-n. The response server 3 includes a response processing application program 11, a totalization processing application program 12, an authentication processing application program 13, and an operational application program 14. The response processing application program 11 stores the response data sent from the interactive televisions to a response data file 17 in the form of a file. The totalization processing application program 12 totalizes the response data stored in the response data file 17. The authentication processing application program 13 accesses an authentication information database 16 and extracts personal information. The operational application program 14 activates the application programs 11 to 14 at timings given by a scheduler or deletes unnecessary data from the response data file 17. The response server 3 includes a television program information database 15 and the authentication information database 16. The television program information database 15 can be accessed from the response processing application program 11, the totalization processing application program 12, and the authentication processing application program 13. The authentication information database 16 can be accessed from the authentication processing application program 13. The television program IDs of all television programs provided by the interactive television are registered in the television program information database 15. Necessary procedure data corresponding to the contents of services of these television programs are stored in a one-to-one correspondence with the television program IDs of the television programs. Personal information such as names and addresses are stored in the authentication information database 16 in a one-to-one correspondence with the television IDs of all interactive televisions previously registered. A distributed TP monitor (distributed transaction process monitor) 20 is software which assures the continuity of data by monitoring the operations of the application programs 11 to 14. A high-speed file system 21 is software which is interposed between the application programs 11 to 14 and the databases 15 and 16, the data file 17, and a data file 18. The high-speed file system 21 improves the reliability and increases the processing speed. A communication control unit 30 connects the response server 3 to the interactive televisions 1-1 to 1-n via the public communication network 4. The communication control unit 30 controls connections between the interactive televisions and a modem 32 and connects the interactive televisions connected to the modem 32 to the response server 3 via a communication protocol 33. The communication control unit 30 is connected to the response server 3 via an I/O control unit 34. The I/O control unit 34 efficiently processes data exchange with respect to the response server 3. FIG. 4 shows the configuration of the program information database 15. The program information database 15 stores a procedure for response data in an interactive television program relating to a service of "receiving answers from viewers in a quiz show by using interactive televisions and informing the broadcasting station 2 of the result of totalization of the viewers' answers". Data determined in the television program information database 15 are the television program ID of the program, the broadcasting time of the quiz show, and the procedure (including the method of arranging response data, the method of totalization, and the type of transmitting the totalization result). FIG. 5 shows the configuration of the authentication information database 16. The names of the owners of interactive televisions, the addresses of the owners, and other arbitrary attribute data are determined in a one-to-one correspondence with television IDs. FIG. 7 shows a system configuration for interconnecting the interactive televisions 1-1 to 1-n, the broadcasting station 2, the response server 3, and the IP/SP company servers 7. As described above, the interactive televisions 1-1 to 1-n are connected to the communication control units 30 via the public communication network 4 and modems. The communication control units 30 are arranged on a LAN 35 to which the response server 3 is connected, thereby connecting the interactive televisions and the response server. The communication control units 30 are connected from the LAN 35 to a WAN 37 via a router 36 and connected from the WAN 37 to a broadcasting station terminal 2' via a router 38. The communication control units 30 are also connected from the WAN 37 to the IP/SP company servers 7. The operation of the television system with the above configuration will be described in detail below. FIGS. 8 and 9 illustrate the flows of data when a service is provided on the television system by which responses (answers) from viewers to questions are totalized by the response server 3 and the broadcasting station 2 is informed of the result of totalization in an interactive television program pertaining to a quiz show. The broadcasting station 2 transmits an interactive television program which allows viewers to choose alternative questions and is multiplexed on broadcast radio waves of the quiz show. The television program ID of this interactive television program is added to the program composition information (consisting of screen images and programs) of the interactive television program. When this quiz show is selected, the signal processing circuit 25 and the audio circuit 27 of each of the interactive televisions 1-1 to 1-n output pictures and sounds of the quiz show. Assume that a channel tuning signal for the interactive television program by which a viewer responds to alternative questions is input from the remote control switch 24. The tuner 22 receives the channel tuning signal of the interactive television program from the channel tuning and response identification circuit 23, separates the interactive television program from the broadcast radio waves, and transfers the program to the television program control unit 8. Thereafter, the program composition information of the interactive television program is kept provided to the program control unit 8 until another channel tuning signal is input or the interactive television program is concluded. The program control unit 8 receives the data of the interactive television program from the tuner 22 and displays an image showing a question asked in the quiz show. For example, the question screen consists of a plurality of choices, and a message for prompting a viewer to pick up one choice is displayed on the screen. When the viewer inputs the choice number from the remote control switch 24, the channel tuning and response identification circuit 23 inputs the response (choice number) received from the remote control switch 24 to the program control unit 8. Upon receiving the response, i.e., the choice number, from the channel tuning and response identification circuit 23, the program control unit 8 adds the television program ID of the presently selected interactive television program and the television ID of the interactive television to the response (choice number: answer) and transfers the response data to the communication control unit 9. The communication control unit 9 sends a line connection request from this interactive television to the communication control unit 30 of the server 3 via the public communication network 4. After the communication control units 9 and 30 are connected, the response data added with the television program ID and the television ID is transmitted from the interactive television to the response server 3. In the response server 3, the I/O control unit 34 receives the response data transmitted from the interactive television and analyzes the header of the response data. If the data is identified as response data, the I/O control unit 34 transfers the data to the response processing application program 11. After transferring the response data to the response processing application program 11, the communication control unit 30 of the server 3 disconnects the interactive television and waits for reception of response data from another interactive television. The I/O control unit 34 discretely supplies to the response processing application program 11 response data to various television programs from the interactive televisions 1-1 to 1-n. As shown in FIG. 6, the response processing application program 11 arranges the response data to various television programs in accordance with the television program ID and stores the data in the data file 17. A response data list is formed by arranging and storing the response data in the file form in accordance with the television program ID. More specifically, a procedure which gives an instruction to "arrange response data in a file form in accordance with the television program ID" is set in the television program information database 15. The response processing application program 11 reads out the procedure from the television program information database 15 by using the television program ID added to the response data as a key. The response processing application program 11 retrieves a file having the corresponding television program ID from the response data file 17, extracts the television ID and the response data (answer) from the response data, and sets the extracted data in the bottom line of the file. By executing this processing for all answers, a list of the response data to the interactive television program pertaining to the quiz show, i.e., an answer list, is formed. An instruction to "add personal information of an answerer" can be included in the procedure of the interactive television program registered in the television program information database 15. If this is the case, the response processing application program 11 or the totalization processing application program 12 sends the instruction to the authentication processing application program 13. On the basis of the television ID registered in the response data list, the authentication processing application program 13 searches the authentication processing database 16, reads out personal information of an answerer, and transfers the readout personal information to the response processing application program 11 or the totalization processing application program 12. On the basis of the television program ID, the totalization processing application program 12 reads out the method of totalization corresponding to the program from the television program information database 15. In this embodiment, a method of totalizing the answers to the questions asked in the quiz show is acquired as the procedure. Therefore, the totalization processing application program 12 reads out and totalizes the response data (answers), by using the television program ID as a key, from the response data file 17 formed by the response processing application program 11. If the totalization processing involving the personal information of answerers is designated in the procedure, the totalization processing application program 12 totalizes the response data by combining the response data list and the personal authentication information. The result of totalization is output in a form corresponding to the transmission type registered in the television program information database 15. When the broadcasting station 2 wants to use the totalization result of answers in the television program, "real time transmission" is designated as the transmission type. The communication line between the response server 3 and the broadcasting station terminal 2' is connected, and the totalization result is transmitted to the broadcasting station terminal 2' via the WAN 37. In the above explanation, answers from viewers are totalized in a quiz show. However, the contents of services which can be provided to viewers in interactive television programs can be freely set by the combination of the contents of a program to be multiplexed on broadcast radio waves from the broadcasting station 2 and the procedure of the program previously stored in the program information database 15. As an example, it is possible to provide a service by which viewers can request catalogues of articles advertised in commercial breaks between television programs by using an interactive television program. That is, an interactive television program for displaying a screen for requesting an article catalogue is multiplexed on broadcast radio waves in a commercial break by setting the television program ID. A viewer of the interactive television 1 inputs a channel tuning signal for selecting the interactive television program for catalogue request from the remote control switch 24. Consequently, the program control unit 8 receives the catalogue request interactive television program from the tuner 22 and displays a catalogue request screen. The viewer inputs response data to the catalogue request screen from the remote control switch 24. The program control unit 8 adds the television program ID and the television ID to the input response data and transmits the data to the response server 3. In the program information database 15 arranged in the response server 3, procedures for response data relating to these catalogue request interactive television programs are previously registered on the basis of the television program IDs. The interactive televisions 1-1 to 1-n send response data relating to the catalogue request interactive television programs to the server 13. The response processing application program 11 arranges the response data in units of programs. The totalization processing application program 12 executes totalization processing necessary for the catalogue request on the basis of the procedure registered in the program information database 15. More specifically, the totalization processing application program 12 designates the television IDs and instructs the authentication processing application program 13 to extract the personal information, e.g., the names and the addresses, of individuals who have requested catalogues from the authentication information database 16. The totalization processing application program 12 then forms a catalogue request list showing the correspondence between the types of catalogues and the addresses from the personal information extracted from the authentication information database 16 and the television program IDs. Since it is unnecessary to transmit the catalogue request list to the IP/SP company in real time, the totalization processing application program 12 stores the catalogue request list in a totalized data storage unit 18. The catalogue request list is transmitted later by batch processing from the server 3 to the server 7 of the contracting IP/SP company. Note that when the catalogue request list is to be transmitted by batch processing, "batch processing" must be specified in the item of transmission type in the television program information database 15. Also, a plurality of catalogue request lists can be simultaneously transmitted when the broadcasting station 2 or the IP/SP company server 7 demands the response server 3 of the transmission. For this purpose, "on demand" is specified in the item of transmission type in the television program information database 15. The totalization result obtained by the totalization processing application program 12 of the response server 3 is not only transmitted to others but also printed out in the response server 3 or displayed on a CRT depending on the purposes. Note that the work of forming a list, such as a catalogue request list, in which personal information needs to be processed, can be transferred to the authentication processing application program 13. In the above illustrated example, the totalization processing application program 12 gives the television ID information to the authentication processing application program 13 and makes the function 13 to form a catalogue request list. In a system of the kind described above, the interactive televisions 1 receive broadcast radio waves on which programs are multiplexed and selectively display the programs. The interactive televisions 1 accept responses from viewers and transmit these input choices as response data, together with television program IDs and television IDs, to the response server 3. Response processing and totalization processing application program are performed for the response data by referring to television program information predetermined in accordance with the contents of the individual television programs in the response server 3. Accordingly, it is possible to display arbitrary programs pertaining to television programs or broadcast commercials on the interactive televisions and to collect input choices from viewers as response data. Consequently, information can be provided by properly processing the collected response data in accordance with the contents of the television programs. Personal information is previously registered in a one-to-one correspondence with the television IDs of the interactive televisions 1-1 to 1-n in the authentication information database 16 of the response server 3. Therefore, processed data can be formed by adding the personal information to the response data collected from the interactive televisions 1-1 to 1-n. This allows easy formation of various lists requiring the personal information. In the above arrangement, it is also possible to display programs having no relation to television programs or broadcast commercials and collect response data from viewers of the interactive televisions. The first embodiment of the present invention provides a television system using interactive televisions capable of selecting interactive television programs. The basic system configuration and software configuration of this embodiment are the same as the arrangement described above. However, in this television system, only a program start menu screen (selection screen) displayed when an interactive television program is started up is multiplexed on broadcast radio waves and transmitted from a broadcasting station 2. After the interactive television program is started, a response server (the response server itself or an application program arranged in another server) provides program composition information of the interactive television program. Each of interactive televisions 1-1 to 1-n adds the television program ID and the television ID to the response data from the viewer. An I/O control unit 34 of a response server 3 adds a header to the response data and transmits the data. The header functions as an identifier by which the response data is transferred to an online service manager 19. The online service manager 19 has a function of searching a television program information database 15 on the basis of the television program ID added to the response data and specifying an application program to be connected to a communication control unit 30. In the television program information database 15, connection destination application information is registered in television program information of each corresponding television program ID. The form of a service provided on this television system will be described below with reference to FIGS. 10 and 11. While commercials are being broadcast, a program start menu screen of an interactive television program such as online shopping or catalogue request is multiplexed on broadcast radio waves and transmitted from the broadcasting station 2. Upon receiving an interactive television program tuning signal from a remote control switch 24, each of the interactive televisions 1-1 to 1-n displays the program start menu screen through the channel of the selected interactive television program. Thereafter, the online service between the interactive television and the response server 3 starts independently of the broadcast program from the broadcasting station 2. When a program start request is input to the program start menu on the interactive television, response data indicating the program start request, which is added with the television program ID, the television ID, and an interactive header, is transmitted from a communication control unit 9 of the interactive television to the response server 3. The I/O control unit 34 of the response server 3 analyzes the header of the response data. If the header of the response data is an interactive header, the I/O control unit 34 transfers the response data to the online service manager 19 and maintains the connection of the communication line. The online service manager 19 reads out connection application information from the television program information database 15 by using the television program ID added to the response data as a key, and activates the application program specified in the readout connection application information. If an application program 41 arranged in the response server 3 is specified in the connection application information, this application program 41 transmits program composition information such as images and scripts corresponding to the contents of the television program to the interactive television as request source via a public communication network 4. In the interactive television which has received this program composition information such as images and scripts, a program control unit 8 executes a program unit of the program composition information, thereby outputting images and, in some instances sounds, of the interactive television program. When the viewer inputs a response signal to this interactive television program by using the remote control switch 24, response data formed by adding the television program ID and the television ID to this response is transmitted to the response server 3. In the response server 3, the response data is transferred to the application program 41. Upon receiving the response data, the application program 41 transmits images or scripts for starting the next processing to the interactive television. The shopping procedure or the catalogue request procedure is completed by similarly repeating the exchange of the response data and the program composition information between the server 3 and the interactive television. If the contents of the procedure are simple, the procedure is completed only by transmitting the response data once. If the application program specified in the connection application information read out from the television program information database 15 by the online service manager 19 by using the television program ID as a key is not arranged in the response server 3, the line is connected to another server 40-1 (40-2) in which this specified application program is arranged. It is assumed that address information for connecting the line to the server 40-1 (40-2) is set in the television program information database 15. For example, if an application program 42 arranged in the server 40-1 is specified in the connection application information, the response server 3 is connected to the server 40-1 via a high-speed digital network to activate the application program 42. The composition information such as images of the interactive television program is transmitted from the application program 42 to the interactive television 1 via the response server 3. By arranging the application program 42 and an application program 43 in the servers 40-1 and 40-2 managed by providers of articles, the procedures of online shopping and catalogue request can be directly transferred to the article providers. In this embodiment as described above, the program start menu of an interactive television program is multiplexed on broadcast radio waves and broadcast from the broadcasting station 2. Each interactive television adds the television program ID, the television ID, and the interactive header to response data and transmits the response data to the response server 3. An application program arranged in the response server 3 or in another server transmits images and programs to the interactive television via the response server 3. Therefore, by initially transmitting only the program start menu from the broadcasting station 2 to the interactive televisions, the application program of the response server 3 can provide the subsequent procedure. Accordingly, online shopping and catalogue requests using the interactive televisions can be performed without increasing the load on broadcast radio waves. Also, the program start menu of an article pertaining to a commercial or a television program being broadcast can be selected by the interactive television. In the above embodiment, the program start menu is transmitted from the broadcasting station 2 to the interactive televisions. However, the program start menu of an interactive television program having no relation to a commercial or a television program being broadcast can be previously stored in a ROM of the interactive television and displayed at any time. (Second Embodiment) FIGS. 12 and 13 illustrate a modification of the above embodiment. In this television system, a menu of interactive services provided by a server is previously stored in a storage medium of an interactive television, and a viewer can select a service on the interactive television. The services provided to the interactive television by the server can be processed as one form of interactive television programs in the same manner as in the second embodiment. Upon receiving a request to display the provided service menu from a viewer, an interactive television 1 displays the menu previously stored in a storage medium such as a ROM. When the viewer selects one provided service from the menu, data as a start request operation is added with the service ID, the television ID, and a header for requesting interactive communication and transmitted from a communication control unit 9 of the interactive television to a response server 3. Service IDs are registered instead of television program IDs in a program information database. The subsequent processing is identical with that in the second embodiment. In this embodiment as described above, online shopping and catalogue requests can be performed by the interactive television independently of broadcasting from a broadcasting station. (Third Embodiment) Figure 14 shows functional blocks of a television system according to the third embodiment. In this television system, an interactive television 1 for receiving broadcast radio waves transmitted from a broadcasting station 2 and displaying programs can be connected to a response server 3 via a public communication network 4. The interactive television 1 basically has the same functions as those of the interactive television used in the television system described above. That is, the interactive television 1 has a function of separating sounds and images of a program multiplexed on broadcast radio waves transmitted from the broadcasting station 2, a function of converting the television program into a television signal in accordance with a program selection request (channel tuning operation) and displaying the television signal, and a response function of transmitting response data input by a viewer to a multiplexed program to the response server 3. In this interactive television 1, a remote control operation receiving unit 23' transfers a viewer's response signal received from a remote control switch 24 to a program control unit 8. The remote control operation receiving unit 23' is obtained by separating the function of a response identification circuit from a channel tuning and response identification circuit. The program control unit 8 executes an interactive television program separated from broadcast radio waves, receives a response from a viewer, adds the television program ID and the television ID to the response, and transfers the response to a communication control unit 9. This television program ID is simultaneously transmitted on broadcast radio waves when the program is transmitted from the broadcasting station 2 to the interactive television 1. The television ID is set for each interactive television 1. Information fields of the television ID include a television information field and a personal information field. In the television information field, an inherent television ID of the interactive television 1 is set. In the personal information field, a personal ID for specifying a viewer who inputs response data when the interactive television 1 is shared by a plurality of persons (e.g., members of family) is set. FIG. 15 shows the structure of the remote control switch 24. More specifically, FIG. 15 is a perspective view of DIP switches arranged on the rear surface of the remote control switch 24. DIP switches 100 consist of four switches 100a to 100d each of which can be set to two states, "up" and "down". A personal ID can be set by combining "up" and "down" of the switches 100a to 100d. Dedicated remote control units are provided to a plurality of persons who use the same interactive television, and the personal ID of each person is set in the corresponding remote control unit. When a single remote control unit is shared by a plurality of persons, the personal ID of a person to whom interactive television programs are provided by the interactive television is set by the DIP switches 100. When transmitting the response data to the interactive television 1, the remote control switch 24 simultaneously transmits the personal ID set by the DIP switches 100. The program control unit 8 forms the television ID by combining the personal ID received from the remote control switch 24 and the unique television ID of the interactive television 1. FIG. 16 shows the data structure of the television ID formed by the program control unit 8. This television ID is added together with the television program ID to the response data. The response server 3 includes a television program information database 15 and an authentication information database 16. As in the first embodiment, procedures for response data to individual programs are registered in units of programs in the television program information database 15. In the authentication information database 16, the television IDs of all interactive televisions 1-1 to 1-n previously registered and the personal information such as the names and the addresses of the users are registered. FIG.17 shows the data structure of the authentication information database 16. The authentication information of previously registered viewers (users) are registered in this authentication information database 16, and the pieces of authentication information are classified in accordance with the television ID. A plurality of personal IDs can be set for one television ID (interactive television), and various pieces of authentication information are previously set for each personal ID. That is, the pieces of authentication information of an arbitrary number of persons are registered for one interactive television 1. The authentication information consists of the password and the area code as well as the name, the address, the age, and the sex. The operation of the television system with the above configuration will be described below. The operation will be described by taking as an example the form of a service by which "responses from viewers to a quiz show are totalized by the response server 3 and the broadcasting station 2 is informed of the result of totalization". Program data of an interactive television program consisting of screen images and scripts for allowing a viewer to choose answers to alternative questions is broadcast on broadcast radio waves from the broadcasting station 2 to the interactive televisions 1. This program data contains the television program ID registered in the television program information database 15. When a viewer transmits a signal for requesting an answer selection program from the remote control switch 24 to the interactive television 1, the interactive television 1 separates program data of the answer selection program (interactive program) from the broadcast radio waves of the quiz show and supplies the data to the program control unit 8. The program control unit 8 converts the program data of the answer selection program into a television signal and displays a selection menu for allowing the viewer to choose an answer on the television screen. When the viewer inputs the answer number by operating buttons on the remote control switch 24, this answer number is transmitted together with the personal ID data set by the DIP switches 100 of the remote control switch 24 to the interactive television 1. The program control unit 8 of the interactive television 1 receives the answer number (response data) and the personal ID number from the remote control switch 24 and forms a television ID from the personal ID data and the television ID of the interactive television 1. The program control unit 8 adds the television ID including the personal ID and the television program ID described above to the answer number (response data) received from the viewer and transfers the response data to the communication control unit 9. The communication control unit 9 sends a line connection request from the interactive television 1 to a communication control unit 30 of the response server 3 via the public communication network 4. After the line is connected between the communication control units 9 and 30, the response data added with the television program ID and the television ID is sent from the interactive television 1 to the response server 3. A large number of interactive televisions 1 send response data to the response server 3 via the public communication network 4. In the response server 3, a response processing application program 11 reads out a procedure of the answer selection program from the television program information database 15 by using the television program ID added to the response data as a key, and executes processing in accordance with the contents of the procedure. In this embodiment, the response processing application program 11 forms a response data file 17 indicating the correspondence between the television IDs and the response data in the answer selection program. Since a plurality of different programs are simultaneously provided, the response data file 17 is formed for each program. By using the television program ID of a program for which the response data file 17 is formed as a key, a totalization processing application program 12 loads the contents of totalization processing performed for the program from a television program information database 14. If processing based on the personal authentication information corresponding to the television ID is specified as the contents of totalization processing, an authentication processing application program 13 is activated. In the case of totalization of answers in a quiz show, it is possible to specify totalization processing of "totalizing answers to quizzes in accordance with the age and the sex". The authentication processing application program 13 authenticates the television ID of each response data registered in the response data file 17 of the program specified by the totalization processing application program 12. If the authenticated television ID is "XXXX01", the authentication information (age·sex) of "TARO" is extracted from a plurality of persons capable of inputting response data to the interactive television 1. If the television ID of the response data from the same interactive television 1 is "XXXX02", the personal ID indicates "HANAKO". Accordingly, the authentication information (age·sex) of "HANAKO" is extracted. Likewise, authentication information is extracted on the basis of the television ID (television ID + personal ID) for all response data registered in the response data file 17. The totalization processing application program 12 totalizes the response data by using the authentication information extracted by the authentication processing application program 13, i.e., totalizes all answers on the basis of the age and the sex. This totalization result is output in a form corresponding to a transmission type registered in the television program information database 15. If the broadcasting station 2 uses the result of totalization of answers in the television program, "real time transmission" is specified in the television program information database 15. The communication line between the response server 3 and the broadcasting station 2 is connected, and the totalization result is transmitted to the broadcasting station 2 via a WAN. In the above explanation, answers from viewers to a quiz show are totalized. However, the contents of programs processable by the response server 3 can be freely changed by the combination of programs multiplexed on broadcast radio waves from the broadcasting station 2 and television program information previously stored in the television program information database 15 in accordance with the programs. As an example, catalogues of articles being commercially broadcast can be requested by the interactive television. That is, program data consisting of screen images and programs for requesting article catalogues is multiplexed together with the television program ID on broadcast radio waves and broadcast in a commercial break. If the catalogue request program is requested from the remote control switch 24 to the interactive television 1, the program control unit 8 executes the programs of the catalogue request program and displays information for a catalogue request on the television screen. A viewer watching the displayed catalogue request screen performs a button operation for the catalogue request from the remote control unit 24. The response data indicated by this button operation and the personal ID data are transmitted from the remote control unit 24 to the remote control operation receiving unit 23' of the interactive television 1. The program control unit 8 forms a television ID by combining the personal ID data and the television ID, adds this television ID and the program ID to the response data, and transmits the data to the response server 3. In the response server 3, program information for this catalogue request is previously registered together with the television program ID in the television program information database 15. The response processing application program 11 forms a response data file 17 for the catalogue request program from the catalogue request response data. On the basis of the television program ID of the catalogue request program for which the response data file 17 is formed, the totalization processing application program 12 reads out the contents of totalization processing necessary for the catalogue request from the television program information database 15. The authentication processing application 13 is instructed to extract the personal information such as the name and the address of each individual who has requested the catalogue. On the basis of the television ID of each response data, the authentication processing application program 13 extracts the personal information such as the name and the address of each individual who has requested the catalogue from the authentication information database 16. In the television ID added to each response data, not only the television ID of the interactive television 1 but also the personal ID indicating the individual (the person who has requested the catalogue) who has actually input the response data are registered. Therefore, the personal information such as the name and the address of the person whose has requested the catalogue can be extracted. From the personal information and the television program IDs, the totalization processing application program 12 forms a catalogue request list showing the correspondence between the types of catalogues and the addresses. Since the catalogue request list need not be transmitted to an IP/SP company in real time, a totalized data file 18 is formed to store these catalogue request lists. The stored catalogue request lists can be transmitted by batch processing to the server of a contracting IP/SP company. Also, depending on the contents of a program, a viewer is requested to input a password to the interactive television 1 in order to identify himself or herself. For example, a viewer is requested to input a password when a program such as television shopping accepts an order from the viewer. More specifically, while a television shopping program is being broadcast the program control unit 8 of the interactive television 1 displays a screen for prompting input of a password, as shown in FIG.18 , to instruct a viewer to input a password. A password is determined in the same manner as for a password of a cash card of a bank for each television or each individual and registered in the authentication information database 16. FIG.17 shows the authentication information database 16 in which a password is registered for each individual. When a password is input from the remote control switch 24 to the interactive television 1, the program control unit 8 adds the password to the television ID including the television program ID and the personal ID and the response data, as illustrated in FIG. 19, and sends the password and the data to the communication control unit 9. The communication control unit 9 transmits the password and the response data to the response server 3. In the response server 3, passwords are previously set in respective corresponding locations of the authentication information database 16 on the basis of the personal IDs. Also, processing of "password check" is designated as the contents of response processing or the contents of totalization processing with respect to the program in the television program information database 15. The totalization processing application program 12 executes the "password check". The response processing application program 11 receives the response data from the interactive televisions 1 and forms a response data file 17 consisting of the television IDs and the response data (orders for articles) on the basis of the contents of response processing for the program read out from the television program information database 15. The totalization processing application program 12 reads out the contents of totalization processing in which the "password check" is designated from the television program information database 14 by using the television program ID in the response data file 17 as a key. The authentication processing function 13 is informed of a television ID and reads out a password corresponding to the informed television ID from the authentication information database 16. Whether the password registered in the authentication information database 16 agrees with the password added to the response data is checked. If the two passwords agree, it is determined that the order for an article is from the person himself or herself, and so the order is accepted. If the two passwords disagree, on the other hand, it is not determined that the order for an article is from the person himself or herself. Accordingly, the order is rejected. The personal information such as the name and the address is extracted from each response data which is found to be an order for an article from the person himself or herself, and an order list consisting of these names and addresses is formed for each ordered article. The order lists thus formed for the individual articles are transmitted online to article distributors or the broadcasting station 2. Note that the above operation is not limited to television shopping. That is, in any program in which it is necessary to check the agreement between response data and a sending person, a viewer is requested to input a password together with response data and the response server 3 checks the password. In this embodiment as described above, a personal information field is formed in a television ID added to response data in the interactive television 1, and not only a television ID but a personal ID of each person who inputs the response data is transferred to the response server 3. In the authentication information database 16 arranged in the response server 3, personal information is registered on the basis of the television ID consisting of the television ID and the personal ID. Accordingly, it is possible to identify not only one registered representative of the interactive television 1 but also a plurality of other viewers sharing the interactive television 1. Even when one interactive television 1 is shared by a plurality of persons, therefore, the response server 3 can totalize response data on the basis of the personal information of each individual who has input the response data. This makes accurate totalization processing feasible and increases the reliability of the result of totalization. In this embodiment, a personal information field is formed in a television ID added to response data in the interactive television 1, and a password input by an individual who has input the response data is transmitted to the response server 3. These passwords are registered in a one-to-one correspondence with television IDs or personal IDs in the authentication information database 16 arranged in the response server 3, and collated in the response server. Accordingly, it is possible to check whether response data sent to the response server 3 is actually input by the person himself or herself. Consequently, it is possible to prevent the inconvenience that a person other than the authorized user intentionally performs a button operation and orders an article against the will of the authorized user. It is also possible to prevent the inconvenience that an order for an article is issued from a wiretapped interactive television 1 without the authorized user knowing it. In the above embodiment, the DIP switches 100 are provided on the rear surface of the remote control switch 24 to input personal ID data to the interactive television 1. However, the program control unit 8 can also input the personal ID in accordance with a flow chart shown in FIG. 20 That is, assuming that a viewer depresses a menu selection button for selecting one program while the program control unit 8 is displaying a menu screen showing a list of programs which can be provided. Upon receiving this input, the program control unit 8 displays a screen, such as shown in FIG. 21, for prompting the viewer to input a personal ID, on the television. When the personal ID data is input by a button operation on the remote control switch 24, this personal ID is set in the personal information field of the television ID. Note that the viewer can input the personal ID at any timing at which the ID can be transmitted together with response data to the response server 3. (Fourth Embodiment) FIG. 22 shows functional blocks of a server system according to the fourth embodiment. In this server system, as in the first embodiment described earlier, an interactive television 1 can be connected to a response server 3 via a public communication network 4. The same reference numerals as in the first embodiment denote parts having the same functions in the sixth embodiment. A television ID transmitted from the interactive television 1 to the response server 3 includes a television information field and a television maker information field in which a maker ID indicating the television maker is registered. Since the television ID and the maker ID of each interactive television 1 are already known and fixed, these IDs are previously set in the television ID of the interactive television 1. A program control unit 8 of the interactive television 1 adds the television ID include the television ID and the maker ID to response data and transmits the data to the response server 3. A response processing application program 11 of the response server 3 forms a response data file 17 from the response data and also forms a television ID file 121 from the television IDs added to the response data. A television maker database 122 in which the names of television makers are registered in a one-to-one correspondence with the maker IDs is arranged in the response server 3. A maker classification application program 123 extracts the names of makers corresponding to the maker IDs registered in the television ID file 121 from the television maker database 122 and forms maker television ID files 124 in which the television IDs are classified in accordance with the maker. The maker television ID files 124 can be used as customer information of the individual television makers. For example, by using the television IDs registered in the maker television ID file 124 of a television maker A as keys, it is possible to extract the corresponding personal information (e.g., the names and the addresses) from an authentication information database 16 and form a list of customers who own televisions made by the television maker A. Also, by totalizing the responders registered in the maker television ID files 124 in accordance with the area and the age by searching the authentication information database 16, the degree of spread of each maker in each area for each age can be checked. In addition, any desired customer information can be formed by combining arbitrary keywords. In this embodiment as described above, a vender field is formed in the television ID of each interactive television 1, and the maker ID is set in this vender field and transmitted to the response server 3. The response server 3 extracts the television IDs and forms the maker television ID files 124 classified in accordance with the maker. Consequently, customer information of the individual television makers can be obtained by the response server 3. ( Fifth Embodiment) FIG. 23 shows functional blocks of a server system according to the fifth embodiment. In this server system, as in the embodiments described above, an interactive television 1 which receives radio waves broadcast from a broadcasting station 2 and displays programs can be connected to a response server 3 via a public communication line 4. A television ID transmitted from the interactive television 1 to the response server 3 contains a television information field and a vender field in which the television maker sets arbitrary information. In this embodiment, a maker ID indicating the television maker, a type ID indicating the type of a television, and the lot number are set in the vender field. The television ID is constituted by the vender information and the television ID. The vender information and the television ID are pieces of fixed information and hence can be previously set in the interactive television 1. A program control unit 8 of the interactive television 1 adds the television ID consisting of the preset television ID and vender information to response data and transmits the data to the response server 3. A response processing application program 11 of the response server 3 forms a response data file 17 from the response data and also forms a television ID file 121 from the television IDs added to the response data. A maker classification application program 123' classifies the television IDs in accordance with the maker in the same manner as described above. Also, the maker classification application program 123' extracts personal information corresponding to each television ID from an authentication information database 16 and forms maker television ID files 124' in which the television IDs added to the personal information are classified in accordance with the maker. The maker television ID files 124' thus formed by the response server 3 are transmitted online or delivered to the individual television makers. FIG. 23 shows a case where the television ID file 124' for a company A is transferred to a television maker A. In the television maker A, the television ID file 124' received from the response server 3 is stored in a file storage 125. A type classification application program 126 reads out the television ID file 124' from the file storage 125 and converts the file 124' into customer information files 128A and 128B in units of television types by referring to a television information database 127. In the television information database 127, type IDs are set in a one-to-one correspondence with types manufactured by the television maker A. Therefore, the type classification application program 126 classifies the television IDs (including personal information) in the television ID file 124' in accordance with the type ID and retrieves the type corresponding to each type ID from the television information database 127 by using the type ID as a key. As a consequence, the customer information files 128A and 128B in which the data classified according to the type ID are added with the corresponding types can be formed. In this embodiment as described above, the television ID transmitted from the interactive television 1 to the response server 3 contains the type ID and the lot number of the television, and the response server 3 forms the television ID files 124' for individual makers. Therefore, it is possible to know the name of the maker, the type, and the lot number of a television owned by a viewer who has transmitted the response data to the response server 3 and the personal information of the viewer. For example, a recall of defective products can be performed by using the television ID file 124'. That is, the corresponding televisions can be found by searching the television ID file 124' by using the type and the lot number as keys, and the names and the addresses of the owners can be found from the personal information added to the television IDs of the found televisions. Also, each television maker can check the sales of individual television types and the spread of each type in each area for each age by using the television ID file 124' of the company. Necessary market data can be extracted by searching the television ID file 124' by using the combination of arbitrary keywords. In the above explanation, all programs are multiplexed on radio waves broadcast from the broadcasting station 2 to the interactive television 1. However, as illustrated in FIG. 11 or 13 already described, only the start menu of each program can be transmitted from the broadcasting station 2 to the interactive television 1 or stored in a ROM of the interactive television 1, and actual programs can be provided from the response server 3 to the interactive television 1. (Sixth Embodiment) FIG. 24 shows functional blocks of a television system according to the sixth embodiment. The sixth embodiment basically has the same configuration as the third embodiment, and so the same reference numerals as in the third embodiment denote parts having the same functions in the seventh embodiment. The object of this embodiment is the form of a service relating to an interactive television program which displays a question which allows a viewer to pick up one of a plurality of choices on an interactive television 1. Accordingly, a program control unit 8 broadcasts an interactive television program consisting of a plurality of questions each having a plurality of choices, and returns a choice unique number assigned to a choice picked up by a viewer to a response server 3 as response data. Mores specifically, a broadcasting station 2 transmits to the interactive television 1 a choice unique number table which, as shown in FIGS.27A to 27C, determines the correspondence between question numbers, choice numbers, and choice unique numbers, for each program. The program control unit 8 converts a choice number picked up by a viewer into a choice unique number by referring to this choice unique number table. A response processing application program 11 processes response data into a predetermined form by referring to a program information database 15. In this embodiment, as illustrated in FIG. 25, a television ID list classified according to the choice unique number is formed in the form of a response data file for each television program ID. A totalization processing application program 12 totalizes the response data files. That is, the totalization processing application program 12 reads out the contents of processing registered in the television program information database 15 for each program and performs totalization processing determined in the contents of processing. In this embodiment, the totalization processing is performed on the basis of the contents of totalization processing defined in a totalization result request stream transmitted online from the broadcasting station 2. The totalization data obtained by the totalization processing application program 12 is stored in a totalized data file 18, read out from the file 18, and transmitted to, e.g., the broadcasting station 2 online or via a certain medium. The contents of the processing of the server system with the above configuration will be described in detail below. In this embodiment, a "question program" is multiplexed and broadcast on radio waves from the broadcasting station 2. In the interactive television 1 which has received the broadcast radio waves, a broadcast signal reception processor 22' extracts program data of the question program and applies the data to the program control unit 8. FIGS. 27A to 27C show examples (examples 1 to 3) of the composition of the "question program". In examples 1 and 2, a program is composed of five questions whose numbers of choices are 3, 4, 6, 3, and 5. In example 1, serial choice unique numbers are given to choice numbers in sequence from choice number 1 of question number 1. In example 2, a choice unique number of two figures whose units digit is the choice number and tens digit is the question number is given to each choice number. In example 3, a program is composed of five questions whose numbers of choices are 2, 3, 4, 2, and 5. In example 3, choice unique numbers are given to choice numbers in alphabetical order from choice number 1 of question number 1. When a viewer inputs a request for a "question program" from a remote control switch to the interactive television 1, the program control unit 8 executes the program of the "question program" and displays questions and choice numbers on the television screen. The viewer chooses one choice number and transfers the number to the program control unit 8 by a remote operation. The program control unit 8 obtains a choice unique number corresponding to the choice number from the choice unique number table of the question program currently being displayed. The program control unit 8 adds the television program ID and the television ID to the response data (choice unique number), as shown in FIG. 26 and issues a transmission request to a communication control unit 9. Similar processing is executed in each interactive television 1 which has received the response data to the "question program". In the response server 3, the response data returned from the interactive television 1 is transferred to the response processing application program 11. The response processing application program 11 reads out the contents of processing from the television program information database 15 by using the television program ID added to the response data as a key. In this embodiment, the contents of the response processing are so determined that data files in which the television IDs are classified in accordance with the choice unique number are formed for the individual program IDs, as shown in FIG. 25. A television ID list is formed for each choice unique number by registering the television IDs added to the response data in a data file of the choice unique number. On the other hand, the broadcasting station 2 transmits a totalization result request online to the totalization processing application program 12 of the response server 3. As described above, desired totalization processing can be performed by the totalization processing application program 12 by previously registering the contents of the totalization processing in the television program information database 15. In this embodiment, however, the broadcasting station 2 directly designates the contents of the totalization processing to the totalization processing application program 12 in real time. FIG.28 shows the format of a totalization result request stream transmitted from the broadcasting station 2 to the totalization processing application program 12. The totalization result request stream contains a communication header, a television program ID (UIC), a request object response data number (CN), a response data length (L), a response data character string (R#n), and a processing method (M). The contents of totalization processing are indicated to the totalization processing application program 12 by this totalization result request stream. For example, to request the totalization processing application program 12 to return the total of the totalized values of response data "11", "12", and "13" in the "question program" with the composition shown in FIG. 27B, a totalization result request stream shown in FIG. 30A is input to the totalization processing application program 12. In accordance with the input totalization result request stream, the totalization processing application program 12 simply adds the totals of the television IDs registered in the data files of choice unique numbers "11", "12", and "13" in question program 1 and transmits the sum to the broadcasting station 1. To request the totalized value of each of the response data "11", "12", and "13", a totalization result request stream shown in FIG. 30B is transmitted to the totalization processing application program 12. A totalization result request stream shown in FIG. 30C requests a personal list of each response data. Upon receiving this totalization result request, the totalization processing application program 12 reads out the television IDs registered in the data files of the designated response data "11" and "12" from a response data file 17 and extracts the personal information from an authentication information database 16 by using the television IDs as keys. The totalization processing application program 12 forms a personal list for each of the response data "11" and "12" and transfers the lists to a designated destination such as a broadcasting station. A totalization result request stream shown in FIG. 30D requests a totalized personal list of persons who have transmitted response data "42" and "54" to question numbers 4 and 5 in the program of example 2. By this totalization result request stream, if the right answer to the fourth question is "42" and the right answer to the fifth question is "54", a totalized personal list of persons who have given the right answers to both the fourth and the fifth questions can be formed. If a totalization result request stream contains a request for a totalized personal list, not all information recorded in the authentication information database 16 is described in the list but only the contents previously registered as program information data in the program information database 15 are returned. If this is the case, the totalization processing application program 12 checks the program ID registered in the totalization result request stream and retrieves the personal information to be described in the personal list from the program information database 15. In this embodiment as described above, unique numbers (choice unique numbers) are determined for all choices in a question program consisting of questions each having a plurality of choices. A choice unique number corresponding to a choice picked up by a viewer is transmitted as response data, together with the television program ID and the television ID, to the response server 3. The response server 3 forms a data file registering the television IDs for each choice unique number. Accordingly, a desired totalization result can be obtained only by transmitting a totalization result request which is the combination of choice unique numbers and the contents of totalization processing from the broadcasting station 2 to the response server 3.
