- The on-air information storage means 372 is for managing an event ID and collation requirements. The collation history storage means 374 is for recording the history related to the collation when the collation is consistent.
- It should be noted that each of these function means is realized by executing special hardware or by the CPU executing the predetermined program stored in the memory, external storage device, or the like.
- Fig. 6 is a flowchart showing a flow of a process of the
information processing system 100 in the present embodiment. First of all, theBML generating server 10 generates a BML for data broadcasting to be broadcasted as a single digital broadcast program associated with a video content (S600). The BML to be generated in the present embodiment includes not only a broadcasting content for a broadcast synchronized with the video content, but also a collation content describing the collation requirements or the like for performing the collation process, the collation content being different from the broadcasting content, and the appendix content for providing a predetermined content (gift) to a viewer when predetermined requirements are fulfilled. Here, the broadcasting content is, for example, a caption displayed in synchronization with the video data, an audience participation game described in a predetermined program language, and the like. The collation content is the content in which are described a condition for generating/transmitting the collation information for checking whether or not a viewer watches a program in real time, and requirements for satisfying the collation. Specifically, the timing for performing collation, the number of collating times required to fulfill the collation requirements, and the like are described. - The
BML generating server 10 transmits the generated BML to the digitalbroadcasting transmission system 20 and thecollation server 30. When a coding process of SSL or the like is performed at the time of the transmission, the security improves. When the digitalbroadcasting transmission system 20 receives the BML, the digitalbroadcasting transmission system 20 configures a digital broadcast program with the video data provided separately, and transmits the program to a digital broadcasting network (S602). - Further, the
collation server 30 acquires a currently-broadcasted program (including video data and BML) from the digitalbroadcasting transmission system 20 via thecommunication line 50, the on-air information acquisition means 362 extracts an event ID to be provided to the header section, stores the event ID in the on-air information storage means 372, reads out the received BML to extract the collation content, associates the collation content with the previously stored event ID, and stores it in the on-air information storage means 372 (S604). - On the other hand, when the
digital broadcasting receiver 40 receives a program for digital broadcasting, the decoding means 462 decodes the program into the header section, video data, and BML, reads out voice data and image data from the video data, and outputs and plays the voice data and image data through thespeaker 418 and the display device 422 (S606). - Furthermore, the
digital broadcasting receiver 40 plays the BML content in parallel with the outputting and playing of the video data. The BML reading means 464 interprets the decoded BML and executes the processing in corresponding to the description. If the broadcasting content is described, the video data and the broadcasting content are synchronized with each other and outputted on the basis of time information (S608). If the appendix content is described, this appendix content is stored in the content storage means 482 (S610). If the collation content is described, the collation requirements such as the timing for performing the collation process and the positional information on thecollation server 30 on the network (IP address, URL, and the like) are acquired from this collation content, and the acquired collation requirements are stored in the collation requirement storage means 484 (S612). - The collating means 466 refers to the collation requirements stored in the collation requirement storage means 484 to determine whether the timing for performing the collation process is reached or not (S614). If the timing for performing the collation process is not reached, the step is returned to S606 to continue the processing. On the other hand, if it is determined that the timing for performing the collation process is reached, the collation process is executed (S616). The detail of the collation process is described hereinafter. Thereafter, it is determined whether predefined collation requirements are fulfiled or not (S618). In the present embodiment, the collation completion receiving means 470 performs the determination of the step S618, depending on whether the notification indicating that the collation requirements are fulfilled or not is received from the
collation server 30. If the collation is not completed, the step is returned to the step S606 to continue the processing. On the other hand, if it is determined that the collation requirements are fulfilled, the appendix content, which is stored in the content storage means 482, is provided at predetermined time such as when a program ends (S620). For example, when the appendix content is an image of a coupon, the coupon image is displayed and outputted to thedisplay device 422. The viewer can bring the displayed coupon to a convenience store or the like and enjoy a benefit such as discount. It should be noted that the time to provide the appendix content may be described in the collation content. Moreover, although not shown, needless to say, the program may be continued even after the appendix content is provided. - Fig. 7 is a flowchart showing a flow of the collation process (S616) in the present embodiment. The collating means 466 refers to the collation requirements stored in the collation requirement storage means 484 to create collation information when the timing for performing the collation process is reached (S700). The collation information comprises an event ID and a machine ID. The event ID acquisition means 468 acquires an event ID provided on the video data which is currently received and outputted, and the collating means 466 uses the event ID as the collation information. Moreover, the machine ID is an identifier for identifying the individual
digital broadcasting receiver 40, and, for example, positional information (IP address) of thedigital broadcasting receiver 40 on the network corresponds to the machine ID. - Thereafter, the
digital broadcasting receiver 40 transmits the collation information, which is created by the collating means 466, to thecollation server 30 via the communication line 60 (S702). Here, the destination of the transmitted collation information is determined as thecollation server 30, which is the destination of transmission, on the basis of the positional information stored in the collation requirement storage means 484. When thecollation server 30 receives the collation information (S704), thecollation server 30 performs collation of the received collation information (S706). In the present embodiment, the event ID in the received collation information and the event ID held in the on-air information storage means 372 are compared and collated with each other. Furthermore, in addition to the collation of the event IDs, the timing (time) at which the collation information is received may be compared and collated with collation timing which is described in the collation content held in the on-air information storage means 372. - As a result of collation, if the received information does not match with the on-air information, the collation process is ended. On the other hand, if the collation information matches with the on-air information, the information indicating that the collation information (the event ID and machine ID) is associated and matched with the on-air information is recoded in the collation history storage means 374 (S708).
- After the recording, the collation confirmation means 366 searches within the collation history storage means 374 on the basis of the machine ID and event ID included in the collation information, extracts a collation history described in the machine ID and event ID, and determines whether the predefined collation requirements (number of collating times and the like) described in the collation content held in the on-air information storage means 372 are fulfilled or not (S71 0).
- If all collations are not yet completed, i.e. if the number of collating times is not sufficient, the collation process is ended. On the other hand, if the collation requirements are fulfilled and required collations are complete, the collation confirmation means 366 transmits, to the
digital broadcasting receiver 40, a notification indicating that the collation is completed (S712). The collation completion receiving means 470 of thedigital broadcasting receiver 40 receives the notification, whereby the predefined collation is completed and it can be checked whether the collation requirements are fulfilled or not (S714). - It should be noted that the order of the steps can be changed optionally without causing any inconsistency in the detail of the process and can be executed in the changed order or in parallel.
- In this manner, the contents such as a coupon image, music, a wall paper, electronic money, points or the like can be provided only to the viewers who watch a program in real time instead of watching a recorded program.
- Hereinafter, the functions and operations of the information processing system are described on the basis of embodiments.
-
Embodiment 1 describes an example of a case in which a coupon is provided only to the viewers who watch a program in real time instead of watching a recorded program, and who also watch the program without performing "commercial skipping" or the like. - Fig. 8 is an example of a digital broadcast program in the present embodiment. Fig. 9 is an image figure of the collating process in the present embodiment. As shown in Fig. 8, suppose that a program starts at 10:00 and ends at 10:30. The program comprises video data and a BML content. The video data is configured with images and voices as with a conventional program. The BML content is the content for data broadcasting, and includes not only a broadcasting content such as a caption, but also a collation content defining collation requirements and an appendix content such as a coupon image.
- First of all, the digital
broadcasting transmission system 20 broadcasts the collation content and the appendix content at an arbitrary time after the program starts. In the examples shown in Fig. 8 and Fig. 9, the collation content having details such as "collation timing: 10:10; 10:20; 10:25, the minimum number of collating times required to fulfill the collation requirements ("collation clearing requirement"): three times" is broadcasted. - When the
digital broadcasting receiver 40 receives the collation content and appendix content, thedigital broadcasting receiver 40 understands the collation requirements and the like through the BML browser and records the collation requirements and the appendix content in the storage means. - When the
digital broadcasting receiver 40 uses an unshown clock or the like to determine that 10:10 is reached, i.e. that the collation timing defined in the collation content is reached, thedigital broadcasting receiver 40 generates collation information having an event ID and a machine ID and transmit it to thecollation server 30. Here, the event ID is incorporated by obtaining, in real time, an event ID, which is provided to a currently-played digital broadcast program when the collation information is generated. In the present embodiment, the event ID of the currently-played program is "123". Also, in the present embodiment the machine ID is "ABC". - The
collation server 30 compares and collates the event ID contained in the collation information transmitted from thedigital broadcasting receiver 40 with the event ID held in the on-air information storage means 372. If the event IDs correspond with each other, a collation history is recorded. - The
digital broadcasting receiver 40 further acquires the event IDs from a program viewed at 10:20 and 10:25 in the same way, and collates the event IDs with each other. - The
collation server 30 checks the collation history every time when each collation ends, and determines whether or not the collation clearing requirement, which is recorded in the on-air information, is satisfied. In the present embodiment, after obtaining the third match, which is the collation clearing requirement, thecollation server 30 transmits a notification of completion of collation. Thedigital broadcasting receiver 40 provides the appendix content upon reception of the notification. - When a recorded program is watched, the event lDs do not match with each other between the collation information and the on-air information. Therefore, a coupon can be provided only to the viewers who watch the program in real time. Moreover, in addition to the security based on the broadcast management policy, the collation process is automatically carried out in the
digital broadcasting receiver 40, thus it is extremely difficult for the viewers to understand the collation requirements such as the timing when collation is performed. For this reason, it is required for the viewers to continuously watch the program in order to obtain the coupon, whereby "commercial skipping" or the like can be prevented. - The above has described the information processing system of the present invention on the basis of the embodiments and the like. However, the present invention is not limited to the embodiments and the like described above and thus can be changed variously within the scope where the gist of the present invention is not deviated.
- For example, in the embodiments, the
collation server 30 receives a BML from the digitalbroadcasting transmissions system 20 via thecommunication line 50 and stores the collation requirements and the like (S604), but the BML may be received via a program circuit. Moreover, the BML which is created by theBML generating server 10 may be received directly. - Further, in the embodiments, the collation process is carried out using an event ID, but a service ID for specifying a channel may be used in addition to the event ID to perform the collation process. In this case, the collation requirements are associated with the event ID and service ID and stored in the on-air information storage means 372 of the collation server 30 (S604), and whether a currently-broadcasted program is viewed or not is checked on the basis of the event ID and service ID when performing collation.
- Furthermore, in the embodiments, the
collation server 30 is provided for each channel, and collation is performed on each channel by means of the individual collation server, but collation can be performed on a plurality of channels by means of asingle collation server 30. At this moment, thedigital broadcasting receiver 40 adds information related to the channels to the collation information, and transmits it to thecollation server 30. - Moreover, in the embodiments, the appendix content is provided when the collation clearing requirement is satisfied, but it is possibly to appropriately change the collation clearing requirement the case in which the appendix content is provided. For example, in the case where the number of collating times is defined as three, if two or more matches out of the three matches are obtained as the collation clearing requirement, a coupon can be provided.
- In addition, the present invention can be applied in general digital broadcasting, but the present invention is particularly effective when the band is narrow as in one-segment broadcasting, because the collation content, which is transmitted to the digital broadcasting receiver in order to carry out the collation process, has a small volume. Moreover, it is particularly effective to apply the present invention to a portable terminal device such as a cellular phone, because the burden of the collation process is small on the digital broadcasting receiver.
- Moreover, the present invention can be applied to cooperate between broadcasting and mileage programs.
