The broadcast station 101 also provides a digital TV broadcast service for the mobile TV receiving terminal 102. In this digital TV broadcasting service, data broadcasting for broadcasting rights information is performed simultaneously with data broadcasting for broadcasting video and audio as contents.

  The mobile TV receiving terminal 102 receives this digital TV broadcast service, and on the other hand, has a function of performing Internet access by a communication function such as a mobile phone.

  The broadcasting station 101 creates and organizes a broadcast program and sells it as a program broadcast frame to the sponsor company 103, and acquires the sponsor company 103 as a sponsor of the program frame. The sponsor company 103 performs CM in the purchased program frame and provides interactive programs (for example, quiz programs and sweepstakes programs) with viewer participation. In such a case, the company's products and services may be provided as premiums for the programs to be provided.

  On the other hand, the mobile TV receiving terminal 102 can receive a broadcast program and can participate in a viewer participation type interactive program using a communication function. When participating in a viewer participation interactive program at the mobile TV receiving terminal 102, an answer to a quiz or application for a sweepstakes is made via the Internet 106 using the communication function of the mobile TV receiving terminal 102.

  The correct answer to the quiz is selected as the program progresses, or the winner is determined by lottery from the prize winner. When the winner is determined, the right information for obtaining the prize for the selected product or service is broadcast to the winner by data broadcasting.

  When broadcasting rights information by data broadcasting, the rights information is encrypted and broadcast to identify the winner. There is encryption method information (for example, key information used for encryption in a specific encryption algorithm) used when encrypting the right information.

  There is a first method for registering this encryption method information in the broadcast server 104 in the broadcast station 101 in advance. Alternatively, when participating in the interactive program, from the portable TV receiving terminal 102, at the same time as the application data for application, the encryption method information is added and transmitted and registered in the broadcast server 104 in the broadcast station 101. There is a second method. By using either method, the broadcast server 104 encrypts the rights information using the encryption method information used when the rights information is encrypted when the viewer is elected, and the data Broadcast by broadcast. Then, only the corresponding viewer who is selected can decrypt the right information by using the pre-registered encryption method information, and the other person cannot decrypt the right information and protect the secret information.

  The broadcast server 104 of the broadcast station 101 manages encryption method information used when encrypting the registered right information for each individual viewer. By managing the encryption method information for each individual viewer, if the viewer is elected, the right information is obtained using the encryption method information used when encrypting the registered right information. Is encrypted and broadcast by data broadcasting.

  The mobile TV receiving terminal 102 that has received the encrypted right information via data broadcasting attempts to decrypt the right information encrypted by the encryption method registered by itself. If you can't decrypt it, you know you are not a winner. If the decryption is successful, it is determined that the player is a winner, and the decrypted right information is stored in the portable TV receiving terminal 102 in the form of an electronic ticket or the like.

  This electronic ticket is provided as a right to exchange for a product or service premium of the sponsor company 103 that provided a quiz program or a prize program. The content is that the right information is electronically recorded in the portable TV receiving terminal 102 as a voucher (a gift certificate) for a product or a gift. When the correct answer to the quiz is selected or the winner is determined by lottery from the sweepstakes applicant, the correct answerer and the winner later bring the mobile TV receiving terminal 102 recorded in the electronic ticket. Visit a store with which the sponsor company 103 is affiliated. Then, the electronic ticket is read by the POS register 403 of the store system 105, and a free gift of the corresponding product or service is obtained.

FIG. 5 is a flowchart showing the operation of the embodiment relating to the operation of the application process from a plurality of viewers for the interactive program. FIG. 6 is a flowchart showing the operation of the embodiment relating to the operation of the broadcast server when a quiz or sweepstakes winner is selected as the program progresses. FIG. 7 is a flowchart showing the operation of the embodiment relating to the presence / absence of winning when the viewer receives the data broadcast and the operation of extracting rights information and exercising the rights when winning.

  First, with reference to FIG. 5, the operation of application processing from a plurality of viewers for an interactive program will be described.

  The broadcasting station 101 starts broadcasting the interactive program, and at the same time inputs data related to the interactive program content to the broadcast server 104 (step S1). Data broadcast content necessary for allowing the viewer to participate in the program is generated (step S2). Broadcasting of the viewer participation interactive program is started (step S3).

  Viewer 1, Viewer 2, Viewer 3, and Viewer n who are willing to participate in viewing the program create application information and apply to the interactive program via communication (via the Internet 106). (Step S4). At the same time, at the same time, in order to obtain the right information for himself / herself when elected, encrypted information that can only be decrypted by him / her is also transmitted. This encryption information corresponds to, for example, a public key based on PKI (step S5). The public key based on PKI is a public key encryption means conforming to “Public Key Infrastructure” PKI (Public Key Infrastructure) which is a security infrastructure using a public key cryptosystem. By having means for providing the public key, the public encryption key is disclosed to the broadcasting station 101. If he / she wins a prize or the like, the broadcasting station 101 broadcasts data broadcasting contents (including right information) encrypted with his / her public encryption key. For this reason, the received encrypted content can be decrypted using the private key held only by itself. Other viewers can receive data broadcast content (including rights information). However, even if the data broadcast content is broadcast, other viewers cannot decrypt the encryption. For this reason, even when data broadcasting content is broadcast using data broadcasting, it is possible to distribute rights information to a specific viewer with security that cannot be decrypted by others.

  This is because if the rights information whose encryption is unique to the entire content (including the rights information) is broadcast as the data broadcast content, the broadcast content is encrypted if it is broadcast as unique to the entire content. Is unique to the entire content. Therefore, it becomes unique for all the viewers who have received it, and it can be obtained from other viewers who are easily receiving the unique encrypted information other than the viewers who have won. For this reason, since the encrypted information is unique for all viewers, it can be easily obtained from others and the rights information can be decrypted and used, so it was not possible to broadcast the rights information in real time.

  The broadcast server 104 associates application information from a plurality of viewers and encrypted information, and stores them in the application information storage unit 304 as application information 305 and encrypted information 306 corresponding to the viewer (step S6).

  Here, in the case of a participating program to which a determination condition as to whether or not the viewer is eligible to participate in the program is given, the broadcast server 104 can determine the participation qualification based on the application information and determine the winning. As described later in the third embodiment, the eligibility for participation is determined from the viewing information recorded as the viewing history of the broadcast in the viewing history management unit 901 provided in the portable TV receiving terminal 102. is there. It is the viewing time or viewing scene requested by the program producer or program provider. Or it is because it recorded whether the data broadcast was recorded and viewed. When the broadcast server 104 receives these pieces of application information from viewers, only viewers who are eligible for the broadcast server 104 to participate in the program can be identified by referring to the application information. In order to determine a viewer who is eligible to record a data broadcast and acquire the right, the time and period recorded as the recording information are recorded together with the recording information in the viewing history information. When the broadcast server 104 receives these pieces of application information from viewers, only viewers who are eligible for the broadcast server 104 to participate in the program can be identified by referring to the application information. Thereby, it is possible to control whether or not the viewer who has performed the viewing requested by the program producer or the program provider can acquire the right. Alternatively, by recording the recorded time and period, it is possible to control whether the viewer who has viewed the recording by viewing the viewing time or the viewing scene requested by the program producer or the program provider can acquire the right.

  Also, the broadcast server 104 manages and aggregates the applied application information 305 and the encrypted information 306, and reports to the program being broadcast by the broadcast station 101 (step S7).

  Next, with reference to FIG. 6, the operation of the broadcast server 104 when a quiz or sweepstakes winner is selected as the program progresses will be described.

  The broadcast station 101 inputs winner information to the broadcast server 104 when a winner is selected by the progress of the program (step S8). In the broadcast server 104, search collation processing is performed based on the inputted winner information. The interactive program winner selection control unit 307 searches and collates application information from each viewer stored in the application information storage unit 304 as application information 305 and encrypted information 306 corresponding to the viewer (step S9). .

  In addition, the broadcasting station 101 inputs information on the selected right (a prize for the selected product or service) (step S10). The broadcast server 104 generates right information content as data broadcast content based on the input right information (step S11).

  From the collation result, the interactive program winner selection control unit 307 extracts the encrypted information stored in association with the application information of the winner. Then, the encryption processing unit 309 encrypts the generated right information content based on the encryption information (step S12). If there are a plurality of winners, this operation is executed a plurality of times.

  The broadcast server 104 outputs the encrypted data broadcast content to the broadcast station 101 (step S13). The broadcast station 101 broadcasts the generated data broadcast content including the encrypted right information as a data broadcast (step S14).

  Next, with reference to FIG. 7, an explanation will be given of the operations related to the extraction of the right information and the exercise of the right when the viewer receives the data broadcast and wins or wins.

  Data broadcasting including the encrypted data broadcasting content is performed from the broadcasting station 101 (step S14). At the same time, the broadcast server 104 distributes to the store system 105 data indicating the right information content distributed by data broadcasting and the content of the rights corresponding to the content (content of the product or service premium) (step S15).

  The mobile TV receiving terminal 102 that has received the data broadcast takes out the data broadcast content including the encrypted right information and attempts to decrypt the cipher using the encryption method designated by itself. At the time of decryption, for example, decryption is attempted using its own private key based on PKI (step S16). If he / she is a winner, his / her public key is provided as encrypted information at the time of application, as shown in the flowcharts of FIGS. Therefore, the encrypted right information received here should be encrypted with its own public key, and in this case, the encryption can be decrypted only with the private key held by itself.

  The selected viewer 1 and viewer n can extract the right information (step S16). Naturally, if you are not a winner, you cannot decrypt the code with your private key.

  The retrieved right information is converted into data that can be exercised by the POS register 403 of the store system 105 (for example, data information of an electronic ticket). The converted data is stored in the portable TV receiving terminal 102 (step S17).

  The viewer (winner) who has acquired the right information goes to a store with the store system 105 and presents an electronic ticket of the right information to the POS register 403. Here, data transmission / reception between the POS register 403 and the portable TV receiving terminal 102 is performed by communication based on IrDA (Infrared Data Association: data communication using infrared rays standardized by this organization). By presenting an electronic ticket or the like of the right information to the POS register 403, the granted right can be exercised (step S18). The store system 105 communicates with the broadcasting station 101 or the sponsor company 103 to perform the settlement based on the exercised information, and performs a settlement process (step S19).

  Next, a second embodiment of the present invention will be described in detail with reference to FIG.

  FIG. 8 is a configuration diagram illustrating a store system according to the second embodiment.

  The basic configuration of the second embodiment of the present invention is the same as that of the first embodiment. However, they devise further information distribution when they visit the store and exercise their rights. The configuration is shown in FIG. In FIG. 8, when the right information is inputted to the POS register 403 in order to exercise the right, the action of the personal information input processing unit 801 prompts to send the viewer's personal information at the same time. The acquired personal information is temporarily stored in the store system 105.

  The acquired personal information is provided to the broadcasting station 101 and further to the sponsor company 103 by the communication control unit 401 when settlement processing is performed by exercising the right, and can be used as an aid for promotion activities. At this time, when requesting personal information, the portable TV receiving terminal 102 may also ask for the viewer's permission.

  Next, a third embodiment of the present invention will be described in detail with reference to FIG.

  FIG. 9 is a block diagram showing a portable TV receiving terminal according to the third embodiment. The basic configuration of the third embodiment of the present invention is the same as that of the first embodiment.

  However, the conditions for receiving the rights information by data broadcasting are further devised. The configuration is shown in FIG.

  A configuration in which a viewer who has applied for a viewer-participation-type interactive program receives distribution by performing encryption based on his / her own encrypted information in which right information for a winner selected during the program is registered in advance is received. This is the same as the first embodiment.

  However, the viewer performs an operation other than normal ordinary telephone communication when viewing the interactive program with the portable TV receiving terminal 102. In this operation, a broadcast reception button is pressed to receive a broadcast. The reception of the broadcast program is started by pressing the reception button. The viewing history management unit 901 provided in the portable TV receiving terminal 102 starts recording the viewing history information of the broadcast program at the same time as viewing the interactive program by pressing the reception button. The viewing history information of the program is managed by the operation of the viewing history management unit 901. With this management, the distribution system of rights information by broadcasting can be configured to grant rights only to viewers who have been viewing to satisfy the demand of the sponsor company 103 that is the program provider.

  For example, once you apply for a quiz or sweepstakes, you stop watching. Thereafter, when viewing is resumed when the right information is distributed by data broadcasting, the CM or promotion of the sponsor company 103 that is broadcast while viewing is not being viewed. Therefore, it is possible to determine that such a viewer has no right to win and discard the received right information by the action of the viewing history management unit 901 in the terminal.

  Of course, if you stop viewing after applying for a quiz or sweepstakes, you will not be able to receive data broadcast content that includes encrypted rights information that will be broadcast afterwards. Therefore, the right cannot be acquired.

  In the conventional system, the notification of winning and the distribution of the right information are performed by a communication and transmission system (for example, e-mail, mail, home delivery, etc.) independent of broadcasting. However, in the present invention, the right information is distributed by broadcasting in real time (real time) during the program. Therefore, the viewing history management unit 901 in the terminal can be associated with the viewing history information of the program. Therefore, it is possible to realize a service that grants a winning right only to the viewer who is viewing the program. As a result, it is possible to provide a service in which the right to obtain a prize for winning a quiz or sweepstakes is given only to a viewer who is watching the TV program in real time in an interactive program with viewer participation. Become.

  In addition, the sponsor company 103 gives the right to obtain a prize for winning a quiz or sweepstakes only to viewers who satisfy specific conditions even if they are not watching TV programs in real time. Service can be implemented.

  Although it is possible to record the data broadcast and acquire the right depending on the configuration, this can also be controlled by the action of the viewing history management unit 901. For example, the recording information for identifying that it is acquired by viewing by recording is recorded in the viewing history information of the program as the recording information. Record the recorded time and duration as recording information. Thereby, it is possible to control whether or not the viewer who has performed the viewing requested by the program producer or the program provider can acquire the right. Alternatively, by recording the recorded time and period, it is possible to control whether the viewer who has viewed the recording by viewing the viewing time or the viewing scene requested by the program producer or the program provider can acquire the right.

  In the case of recording a data broadcast, the mobile TV receiving terminal 102 itself normally records the data broadcast on the video deck. Press the recording start button on the video deck to start recording. At the same time, when a recording button provided in the mobile TV receiving terminal 102 is pressed, the viewing history management unit 901 provided in the mobile TV receiving terminal 102 records the viewing history information of the broadcast program. Later, the viewer can reproduce and acquire the right.

  In this manner, the viewer who has viewed the program requested by the program producer or the program provider can be selected by the action of the viewing history management unit 901 in the terminal. Alternatively, it is possible to select a viewer who has viewed at a viewing time requested by the program producer or program provider, or a viewer who has viewed a viewing scene requested by the program producer or program provider. Or the viewer who recorded and watched data broadcasting can be selected.

  It is possible to perform control such that a service of granting a winning right only to a viewer who is viewing the program can be realized. This is because when the viewer participates in the program, the broadcast server 104 receives application information including identification information such as viewing time, viewing scene, or recording in the application information. This is because the broadcast server 104 can identify only viewers qualified to participate in the program by referring to the application information.

  In the above embodiment, the right information is broadcast and decrypted by encryption based on an instruction from the viewer. However, as another embodiment, instead of performing encryption, it is also possible to broadcast and decrypt rights information in association with the viewer's personal identification information.

  As yet another embodiment, the broadcast content and the right information related to the broadcast content may be broadcast at the same time. If rights information rights are not provided specifically to specific viewers, but provided to any viewer who is eligible to participate in the program (anyone, anytime) It is. In particular, it is possible to distribute rights information without encrypting the rights information and broadcasting it. In such a case, the viewer can unconditionally obtain the broadcasted right information without giving the personal identification information and the decryption information of the encryption to the distribution system.

  As described above, the broadcast rights information distribution system, the broadcast server, the receiver, the broadcast rights information distribution method, and the rights exercise method and program in the store system according to the present embodiment have the following effects. is there.

  Conventionally, in a viewer-participation interactive program, when a viewer wins a quiz or sweepstakes, it has been conventionally possible to notify only by e-mail via communication. Or it could only be notified with a prize shipment. According to the present embodiment, it can be distributed by broadcasting to the winners whose results are found in real time in the broadcast program.

  In addition, in order to obtain prizes for winners of quizzes and sweepstakes, it is possible to simultaneously broadcast a plurality of rights information to a plurality of winners by broadcasting and distribute the rights information in real time. is there.

  In addition, an encryption method (encryption key or the like) used when broadcasting the right information for the viewer is designated in advance from the viewer's receiving terminal. By designating the encryption method, it is possible to protect the right information with a cipher that can only be decrypted and broadcast it in real time by data broadcasting.

  In addition, an individual encryption method (encryption key or the like) used when broadcasting right information for viewers is designated in advance. Thereby, individually encrypted rights information can be broadcast simultaneously, and the rights information can be distributed to a plurality of selected viewers.

  Also, the rights information is broadcast by performing encryption for each viewer using the encryption method information registered in advance by the viewer. As a result, other people who are not applicable except the winner cannot decipher the rights information, so that the rights information is not stolen by others and the confidential information can be protected.

  Further, in the conventional system, the notification of winning and the distribution of the right information are performed by communication and transmission systems (for example, e-mail, mail, home delivery, etc.) independent of broadcasting. However, it is possible to provide a service in which the rights information is distributed by broadcast in real time during the program and associated with the viewing history information of the program, and is given only to the viewer who is viewing the television program in real time.
