BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below. (First Embodiment) FIG. 1 shows the system configuration of an interactive television system according to the first embodiment. In this interactive television system, program data transmitted from the broadcasting station 10 on a broadcast wave is transmitted.
The response data from the viewer received by the interactive television 20 displaying the television program and received by the interactive television 20 is sent to the response server 30 via the telephone line 40.

It is assumed that the broadcasting station 10 multiplexes a program for accepting a response from a viewer into a broadcast wave of a viewer participation type program and sends it to the interactive television 20 installed at home or the like.

The interactive television 20 includes a broadcast wave reception processing section 21 for receiving a broadcast wave transmitted from the broadcasting station 10.
It has. The broadcast wave reception processing unit 21 separates the program data of the interactive television program from the received broadcast wave and executes the program program included in the program data to display the interactive television program on the monitor display unit 22. It is assumed that the viewer inputs the response data for the interactive television program by operating the button on the television remote control switch (remote control). The viewer response data receiving unit 23 receives a signal such as a display selection request of an interactive television program input by the viewer by operating a button on the remote controller, and passes the operation content to the broadcast wave reception processing unit 21.
Further, viewer response data such as product selections and question answers on the interactive television program displayed on the monitor display unit 22 is similarly received by the viewer response data receiving unit 23 and received by the broadcast wave reception processing unit. Input to 21. A server connection request issued from the broadcast wave reception processing unit 21 during the display of the interactive television program is processed by the communication control unit 24. The communication control unit 24 dials the telephone number of the response server 30 in response to the server connection request and connects the line to the response server 30. The program data of the interactive television program requested to be selected by the viewer response data receiving unit 23 is separated from the broadcast wave and stored in the program data storage unit 25. By reading the program data from the program data storage unit 25, the interactive television program can be displayed on the monitor display unit 22 even after the program ends.

The response server 30 is connected to the interactive television 20 by the communication control unit 31 via a telephone line 40. Transmission data including response data transmitted from the interactive television 20 is stored in the response data storage unit 32. The tallying processing unit 33 tallies the response data in the response data storage unit 32 based on the tallying contents instructed by the broadcasting station 10. For example, in the case of an interactive television program for a public opinion poll, the survey responses for each question are sorted by age and region.

Further, the acceptance time determination unit 34 determines whether or not the response server 30 accepts the response data for the program for which the acceptance time zone is defined. The reception time determination unit 34 performs the above determination based on the current time indicated by the clock 35 and the reception time zone information stored in the program information database 36. Registration of the reception time zone information in the program information database 36 is performed by the program information data management unit 37 instructed by the broadcasting station 10.

Next, the processing procedure in the interactive television and the response server in the interactive television system configured as described above will be described with reference to the flowchart in FIG.

A program identifier is added to the interactive television program to be broadcast from now on, and the reception start time and reception end time are stored in the program information database 36. FIG.
Shows the program information database 36 in which the reception start time and the reception end time are stored in association with the program identifier. Here, the program identifier is an identifier defined for each individual program and is sent from the broadcasting station 10 to the interactive television 20 along with program data by being placed on a broadcast wave.

On the interactive television 20, when the viewer participation type program in which the interactive television program transmitted from the broadcasting station 10 is multiplexed is displayed, the interactive television program of the interactive television program is operated by the viewer. Receive a display selection request. While the interactive television 20 receives the display selection request of the interactive television program by the button operation of the remote controller by the viewer,
The program data of the interactive television program for which the display selection request has been made is stored in the program data storage unit 25 together with the program identifier.

For example, in the case of an opinion poll program, program data including a still screen as shown in FIGS. 4 (a) and 4 (b) is separated from a broadcast wave as program data of an interactive television program and stored in the program data storage unit 25. Is stored. Further, in the case of a television shopping program, the program data including a screen for accepting an order for a product introduced in the program is stored in the program data storage unit 25.
Is stored in

A case will be described below in which an interactive TV program for accepting an order for a product introduced in a TV shopping program is a multiplex program. When a viewer watching a TV shopping program broadcast orders a product introduced in the program, an interactive TV program is used during the program broadcast to display a screen displaying the product number, order number, etc. Then, select the order number etc. by operating the buttons on the remote control. This selection information becomes the response data.

While an order may be input during program broadcasting and transmitted as response data to the response server 30, there are cases where the order cannot be placed without the consent of other family members who are not in that location. In such a case, after the person returns, the interactive data TV program corresponding to the TV shopping program can be operated by operating the button on the remote controller.
5 is read out and displayed on the monitor display unit 22. Therefore, for the first time, an interactive TV program is used to input a product order instruction. Therefore, there is a possibility that response data (a product order instruction or the like) to the program may be transmitted to the response server 30 after a long time has passed from the broadcast time period of the actual TV shopping program.

In the interactive television 20, the response data received from the viewer by the viewer response data receiving section 23 is input to the broadcast wave reception processing section 21. When the broadcast wave reception processing unit 21 receives a signal instructing the completion of ordering of products,
As shown in (a), the transmission data obtained by adding the program identifier and the user identifier to the received response data is passed from the broadcast wave reception processing unit 21 to the communication control unit 24 to issue a server connection request. The communication control unit 24 connects to the response server 30 via the telephone line 40 in response to the server connection request, and FIG.
The transmission data of the format shown in is transmitted.

In the response server 30, the communication control unit 31 receives the transmission data sent from the interactive television 20, and also passes the program identifier added to the transmission data to the reception time determination unit 34. The reception time determination unit 34 extracts the reception time zone of the program for the response data from the program information database 36 based on the program identifier, and recognizes the current time indicated by the clock 35. If the recognized current time is within the reception time zone, the response data set in the transmission data is stored in the response data storage unit 32. Then, in order to notify the interactive television 20 that the acceptance is normally completed, a code indicating acceptance is set in the acceptance result of the format shown in FIG. 5B, a program identifier is added, and the communication control unit 31 is added. To the interactive television 20 from which the response data is transmitted via the telephone line 40.

If the current time is not within the reception time zone, a code indicating an error is set in the reception result and a program identifier is added to notify the interactive television 20 that the reception was not accepted. It is transmitted to the television 20.

The interactive television 20 waits for an answer to the response data transmitted to the response server 30, extracts the code set in the acceptance result, and displays the acceptance result on the monitor display unit 22.

As described above, according to the present embodiment, the response server 30 is provided with the clock 35 and the program information database 36 in which the reception time zone is registered based on the program identifier is arranged. Since the program identifier is added to the response data to be sent and the response server 30 manages the reception time zone of the response data, it is possible to send the response data to the viewer who is trying to transmit the response data even though the reception time has passed. An error message can be notified.

(Second Embodiment) An interactive television system according to a second embodiment will be described. In addition,
The interactive television system of this embodiment has the same system configuration as that of the first embodiment described above. Therefore, the same components will be described using the same reference numerals.

In this embodiment, when the broadcast wave reception processing unit 21 of the interactive television 20 receives a request for reproducing an interactive television program, an acceptable inquiry request as shown in FIG. 6A is sent to the response server 30. The communication control unit 31 of the response server 30 is configured to transmit and return the inquiry result as shown in FIG. 6B to the interactive television 20.

The processing procedure in the interactive television system configured as described above will be described with reference to the flowchart of FIG. In this interactive television system, the reception time zone of the response data of each program is registered in the program information database 36 through the program information data management section 37 which receives the instruction of the reception time zone from the broadcasting station 10 prior to broadcasting.

Program data storage unit 25 of interactive television 20
In the same manner as above, it is assumed that the program data of the interactive television program is stored. In the interactive television 20, when the broadcast wave reception processing unit 21 receives a reproduction request of the interactive television program recorded in the program data storage unit 25 from the user by button operation, the initial stage of the program as shown in FIG. The screen is displayed on the monitor display unit 22. At the same time, the transmission data in the format shown in FIG. 6A, which consists of the program identifier of the program for which the reproduction request has been made and the acceptability inquiry request, is passed to the communication control unit 24 and sent to the response server 30 via the telephone line 40. Send.

In the response server 30, when the transmission data shown in FIG. 6A is received from the interactive television 20, the communication control unit 31 extracts the program identifier from the transmission data and passes it to the reception time determination unit 34. As in the first embodiment, the reception time determination unit 34 determines whether or not the current time is within the program reception time period of the program, and returns the determination result to the communication control unit 31. The communication control unit 31 transmits, as an inquiry result, the determination result as to whether the current time is within the program reception time zone of the program, together with the program identifier, to the interactive television 20 as the inquiry source. In other words, if the current time is within the program acceptance time, the inquiry result will be "acceptable".
Set the code of, and if the current time is not within the program reception time zone, set the code of "Error".

The interactive television 20 takes out the inquiry result from the transmission data returned from the response server 30 and shown in FIG. If the code of "error" is set in the inquiry result, "not acceptable" is displayed on the monitor display unit 22 and the program is ended. If a code "acceptable" is set in the inquiry result, for example, the screen of the monitor display unit 22 is switched to the question screen of Fig. 4B and the process of accepting a response from the viewer is started.
Then, the item selected by the viewer on the question screen is transmitted to the response server 30 as response data in the same manner as in the first embodiment described above.

When the response server 30 receives the transmission data in which the response data is set from the interactive television 20, the response server 30 has already determined that the acceptance is possible. The response data is extracted from the data and stored in the response data storage unit 32.
The response data stored in the response data storage unit 32 is processed by the aggregation processing unit 33 according to the processing content instructed by the broadcasting station 110.
Alternatively, the processing is performed according to the processing content set in advance for the program.

As described above, according to this embodiment, an inquiry is sent to the response server 30 at the time when the viewer makes a display selection request for an interactive television program, and the response server 30 obtains an answer of "acceptable". Since the program that accepts response data from the viewer is started above, it is possible to know whether or not acceptance of the program has ended at the start of the program. It is possible to prevent the waste of being unacceptable because it has passed.

In the second embodiment, since the reception time zone is determined at the start of the program, there is a time lag between the acceptance acceptance and the response data transmission. Therefore, it is desirable to set a time considering the above-mentioned time lag in the reception time zone registered in the program information database 36.
