  FIG. 6 is a flowchart showing a processing flow of the information processing system 100 in the present embodiment. First, the BML generation server 10 generates BML for data broadcasting to be broadcast as one digital broadcast program in association with video content (S600). The BML generated in the present embodiment satisfies a predetermined condition and a collation content in which collation conditions for performing a collation process are described separately from the broadcast content in addition to the broadcast content for broadcasting synchronized with the video content. Supplementary content for providing the viewer with predetermined content (bonus). Here, the broadcast content is, for example, subtitles that are displayed in synchronization with video data, a viewer participation game described in a predetermined program language, or the like. The collation content describes a condition for generating / transmitting collation information for confirming whether the viewer is watching a program in real time and a condition for clearing collation. More specifically, the timing for collation, the number of collations required for collation clearing, and the like are described.

  The BML generation server 10 transmits the generated BML to the digital broadcast transmission system 20 and the verification server 30. When encryption processing such as SSL is performed during transmission, security is improved. When receiving the BML, the digital broadcast transmission system 20 configures a digital broadcast program together with separately prepared video data, and transmits the program to the digital broadcast network (S602).

  In addition, the verification server 30 acquires a program (including video data and BML) currently being broadcast from the digital broadcast transmission system 20 via the communication line 50, and the on-air information acquisition unit 362 is an event assigned to the header part. The ID is extracted and stored in the on-air information storage unit 372, and the received BML is read to extract the collation content, which is stored in the on-air information storage unit 372 in association with the previously stored event ID (S604).

  On the other hand, when the digital broadcast receiver 40 receives a digital broadcast program, the decoding means 462 decodes it into a header part, video data, and BML, and further reads out audio data and image data from the video data. The output is reproduced from the display device 422 (S606).

  Further, the digital broadcast receiver 40 reproduces the BML content in parallel with the output reproduction of the video data. The BML reading unit 464 interprets the decoded BML and executes processing according to the description. When the broadcast content is described, the video data and the broadcast content are synchronized and output based on the time information (S608). If the appendix content is described, the appendix content is stored in the content storage means 482 (S610). When collation content is described, collation conditions such as timing for performing collation processing from the collation content and position information (IP address, URL, etc.) of the collation server 30 on the network are acquired and stored in the collation condition storage unit 484. Store (S612).

  The collation unit 466 refers to the collation conditions stored in the collation condition storage unit 484 and determines whether or not the timing for performing the collation processing has arrived (S614). If the timing for performing the collation process has not arrived, the process returns to S606 to continue the process. On the other hand, if it is determined that the timing for performing the matching process has arrived, the matching process is executed (S616). Details of the verification process will be described later. Thereafter, it is determined whether or not a pre-specified collation condition has been cleared (S618). In the present embodiment, the collation completion receiving unit 472 performs the determination in S618 depending on whether or not the collation completion notification is received from the collation server 30. If the collation is not completed, the process returns to S606 and the processing is continued. On the other hand, if it is determined that the collation condition is cleared, the supplement content stored in the content storage means 482 is provided at a predetermined time such as the end of the program (S620). For example, when the appendix content is a coupon image, the coupon image is displayed and output on the display device 422. The viewer can bring the displayed coupon to a convenience store or the like and enjoy benefits such as discounts. The time at which the supplement content is provided may be described in the collation content. Although not shown, it goes without saying that the program may continue to be played after the supplemental content is provided.

  FIG. 7 is a flowchart showing the flow of collation processing (S616) in the present embodiment. The collation unit 466 refers to the collation conditions stored in the collation condition storage unit 484, and creates collation information when the timing for performing the collation process comes (S700). The verification information includes an event ID and a machine ID. In the collation unit 466, the event ID acquisition unit 468 acquires the event ID assigned to the video data currently received and output, and uses the event ID as the verification information. The machine ID is an identifier for identifying each digital broadcast receiver 40, and corresponds to, for example, position information (IP address) on the network of the digital broadcast receiver 40.

  Thereafter, the digital broadcast receiver 40 transmits the verification information created by the verification unit 466 to the verification server 30 via the communication line 60 (S702). Here, the transmission destination of the collation information determines the collation server 30 as the transmission destination based on the position information stored in the collation condition storage unit 484. When the collation server 30 receives the collation information (S704), the collation server 30 collates the received collation information (S706). In the present embodiment, the event ID in the received verification information is compared with the event ID held in the on-air information storage unit 372. Further, in addition to the verification of the event ID, the timing (time) at which the verification information is received may be compared with the verification timing described in the verification content held in the on-air information storage unit 372.

  If the received verification information does not match the on-air information as a result of verification, the verification process is terminated. On the other hand, if the collation information matches the on-air information, the collation history storage unit 374 records that the collation coincides with the collation information (event ID and machine ID) (S708).

  After recording, the verification checking unit 364 searches the verification history storage unit 374 using the machine ID and event ID included in the verification information as keys, extracts the verification history for the aircraft ID and event ID, and stores the on-air information storage unit. It is determined whether a pre-specified collation condition (number of times, etc.) described in the collation content held in 372 has been cleared (S710).

  If all the collations are not yet completed, such as when the number of collations is insufficient, the collation process is terminated. On the other hand, when the verification condition is cleared and the required verification is completed, the verification check unit 364 transmits a notification that the verification is completed to the digital broadcast receiver 40 (S712). The collation completion receiving means 472 of the digital broadcast receiver 40 can confirm that the collation defined in advance has been completed and the collation conditions have been cleared by receiving the notification (S714).

  Note that the steps can be executed in any order or in parallel as long as the processing contents do not contradict each other.

  In this way, it is possible to provide contents such as coupon images, music, wallpaper, electronic cash, points, etc. only to viewers who have watched the program in real time instead of recording.

  Hereinafter, functions and operations of the information processing system will be described based on examples.

  As a first embodiment, an example will be described in which a coupon is provided only to a viewer who views a program in real time instead of watching recorded video and does not perform “CM skip” or the like.

  FIG. 8 is an example of a digital broadcast program in the present embodiment. FIG. 9 is an image diagram of the collation processing in the present embodiment. As shown in FIG. 8, it is assumed that the program starts at 10:00 and ends at 10:30. The program includes video data and BML content. The video data is composed of images and sounds as in the conventional program. The BML content is content for data broadcasting, and includes supplemental content such as collation content defining a collation condition and coupon images in addition to broadcast content such as captions.

  First, the digital broadcast transmission system 10 broadcasts the collation content and the appendix content at an arbitrary time after the program starts. In the example shown in FIG. 8 and FIG. 9, collation content with the content “collation timing: 10:10, 10:20, 10:25, collation clear condition: 3 times” is broadcast.

  When the digital broadcast receiver 40 receives the collation content and the appendix content, the digital broadcast receiver 40 grasps the collation condition and the like with the BML browser, and records the collation condition and the appendix content in the storage unit.

  When the digital broadcast receiver 40 determines that 10:10 has arrived using a clock (not shown), that is, the collation timing specified in the collation content has arrived, the collation including the event ID and the machine ID is performed. Information is generated and transmitted to the verification server 30. Here, as the event ID, the event ID assigned to the digital broadcast program being reproduced at the time of generating the collation information is acquired and used in real time. In this embodiment, it is assumed that the event ID of the program being reproduced is “123”. In this embodiment, it is assumed that the machine ID is “ABC”.

  The verification server 30 compares and collates the event ID included in the verification information transmitted from the digital broadcast receiver 40 and the event ID held in the on-air information storage unit 372. If the event IDs match, a verification history is recorded.

  Similarly, at 10:20 and 10:25, the digital broadcast receiver 40 obtains an event ID from the program being viewed at each time point and performs collation.

  The verification server 30 checks the verification history every time verification is completed, and determines whether the verification clear condition recorded in the on-air information is satisfied. In the present embodiment, after the third collation, which is a condition for clearing collation, is matched, the collation server 30 transmits a notification that the collation is completed. Upon receiving the notification, the digital broadcast receiver 40 provides the supplemental content.

  When a recorded program is viewed, the event IDs do not match between the verification information and the on-air information. Therefore, a coupon can be provided only to a viewer who has watched the program in real time. In addition to the security based on the broadcast operation regulations, since the verification process is automatically performed inside the digital broadcast receiver 40, it is extremely difficult for the viewer to understand the verification conditions such as when the verification is performed. It is. Therefore, in order for the viewer to obtain the coupon, it is necessary to continuously watch the program, and it is possible to prevent “CM skip” and the like.

  Although the information processing system of the present invention has been described based on the embodiments and the like, the present invention is not limited to the above-described embodiments and the like, and various modifications are made without departing from the gist of the present invention. To get.

  For example, in the embodiment, the verification server 30 receives BML from the digital broadcast transmission system 20 via the communication line 50 and stores the verification conditions and the like (S604), but receives BML via the broadcast line. It is good also as what to do. Alternatively, the BML generated by the BML generation server 10 may be directly received.

  In the embodiment, the verification process is performed using the event ID. However, the verification process may be performed using a service ID for specifying a channel in addition to the event ID. In this case, the on-air information storage unit 372 of the verification server 30 stores the verification condition in association with the event ID and the service ID (S604), and when performing the verification, based on the event ID and the service ID, Check if you are watching a program that is currently airing.

  Further, in the embodiment, the collation server 30 is provided for each channel individually and collation is performed by a separate collation server for each channel. However, one collation server 30 is configured to perform collation for a plurality of channels. You can also. At this time, the digital broadcast receiver 40 adds information related to the channel to the verification information and transmits it to the verification server 30.

  In the embodiment, the appendix content is provided when the collation clear condition is satisfied. However, the collation clear condition for when the appendix content is provided can be changed as appropriate. For example, when the number of verifications is defined as 3, the verification clear condition may be set so that a coupon is provided if the verification matches two or more of the three verifications.

  Furthermore, the present invention can be applied to general digital broadcasting. However, since the capacity of collation content transmitted to a digital broadcast receiver for performing collation processing is small, the present invention has a band like one segment broadcasting. This is particularly effective when it is narrow. In addition, the present invention is particularly effective when applied to a portable terminal device such as a cellular phone because the processing load on the digital broadcast receiver side is small when performing the collation processing.
