Here, as a result of the collation, when it is determined that viewing is possible, the viewing control information KT including the decrypted scramble key Ks is generated and supplied to the descrambler 322. Therefore, the descrambler 322 performs the descrambling process based on the viewing control information KT, so that the program for which the viewing contract has been made can be viewed on the program output device 40. When the user views the paper view program, the service ID, the event ID, and the viewing time of the viewed program are supplied to the viewing information storage unit 333 as viewing history information MV.

The contract information storage unit 332 stores the contract information MB supplied from the information analysis unit 331 as described above. In addition, according to the control signal CT from the terminal control unit 34, the contract information MB specified by the “upload type” of the individual information EMM supplied from the broadcast supply side is read from the contract information storage unit 332 and supplied to the modem unit 324. .

In the viewing information storage unit 333, the information analysis unit 3
The viewing history information MV supplied from 31 is sequentially stored.
Also, according to the control signal CT from the terminal control unit 34, every time a predetermined period elapses, or when there is a request to upload the viewing history information indicated by the “other information” of the individual information EMM supplied from the broadcast supply side. Then, the stored viewing history information MV is read and supplied to the modem unit 324.

The modem section 324 is set in advance when a request for the contract information MB or the viewing history information MV is made or when the viewing history information MV is supplied to the modem section 324 after a predetermined period has elapsed. Automatically sends a line connection request to the telephone number on the broadcast supply side. Thereafter, for example, when the line is connected to the broadcast supply side via the public telephone line 45, the requested contract information MB and the viewing history information MV are requested.
Is supplied to the viewing information collection processing unit 18 of the transmission device 10 as the viewer information MU.

The terminal control unit 34 includes an operation input unit 3 including operation keys and a remote control signal receiving circuit.

The receiving unit 3 is controlled by the control signal CT.
By controlling the communication terminal 1, the set-top box 32, and the security module 33, the setting of the operation of the receiving terminal device 30, the switching of the operation, and the process of viewing the paper view program are performed.

In the program transmission system configured as described above, as described above, the contract information MB and the like are uploaded from the receiving terminal device 30 on the viewer side to the transmitting device 10 on the broadcast supply side, and the transmitting device 10 By comparing the contract information MA supplied to the device 30 with the contract information MB uploaded from the receiving terminal device 30 to the transmitting device 10, it is broadcast whether the individual information is correctly transmitted from the transmitting device 10 to the receiving terminal device 30. It can be confirmed on the supply side.

Next, the operation of managing the individual information will be described. When uploading the contract information etc. so that it can be determined whether or not the individual information is correctly transmitted, the timing of this upload is, for example, when an upload request is made from the broadcast supply side or when an upload operation is performed on the viewer side. This is performed at any time when the viewing history information is uploaded or when the viewing history information is uploaded every predetermined period, or at a timing combining these.

Here, when an upload request is made from the broadcast supply side, the viewing information collection processing unit 18 counts up, for example, a count value held as information of “contract information upload instruction”. The contract information MA is generated and supplied to the scramble control unit 16 based on the count value as the “contract information upload instruction” and information such as the work key number and the contract type.
Generates the individual information EMM using the contract information MA, and supplies it to the receiving terminal device 30.

The receiving terminal device 30 decrypts the individual information EMM addressed to itself with the individual key Kp, and determines the count value of the “contract information upload instruction” by, for example, the terminal control unit 34. Here, the terminal control unit 34 stores the count value of the “contract information upload instruction”,
When the individual information EMM is newly supplied, the supplied count value of the “contract information upload instruction” is compared with the already stored count value. At this time, when it is determined that the count value has been counted up, the modem unit 324 and the contract information storage unit 332 are controlled to supply the upload type information indicated by the “upload type” to the modem unit 324 and The data is uploaded from the unit 324 to the transmission device 10 on the broadcast supply side. Also, the terminal control unit 3
At 4, the stored count value is updated to the supplied new count value.

By using the count value in this way, for example, when the contract information MA is changed, the count value is counted up and transmitted to the receiving terminal device 30, and the receiving terminal device 30 counts up the count value. When it is determined that the contract information has been
By uploading the stored contract information, it is possible to efficiently update the contract information and check the update status. In addition, individual information EM
Even if M is repeatedly transmitted, the receiving terminal device 30 does not cause the contract information storage unit 332 to store the same contract information.

When uploading the contract information, for example, as shown in FIG.
0 is transmitted with the addition of a header indicating that the transmitted information is contract information, to the upload information supplied to 0.

As the "upload type", for example, when the upload type is designated as "1", information on the contract type shown in FIG. 7, for example, information indicating that a flat contract is made is uploaded.
When the upload type is designated as “2”, for example, the number of contract information (3) in the flat contract is uploaded. When the upload type is designated as “4”, for example, all contract information in the flat contract,
That is, the information of the three contracted service IDs (1
(00 channels, 101 channels, and 102 channels) are uploaded.

As described above, by transmitting the individual information including the instruction for requesting the contract information, the contract information can be uploaded from the receiving terminal device 30 at the timing desired by the broadcast supply side.

Next, when an upload operation is performed on the viewer side, for example, when upload processing of contract information is performed based on an operation signal US from the operation input unit 35, the terminal control unit 34 reads the contract information from the contract information storage unit 332. Operation signal U
The information of the upload type based on S is read and uploaded from the modem unit 324 to the transmission device 10 on the broadcast supply side. Therefore, by performing an upload operation when it is desired to confirm whether or not the contract information is correct, the contract information can be uploaded to the broadcast supply side.

When the terminal control section 34 determines that the predetermined period has elapsed, the terminal control section 34 controls the modem section 324 and the viewing information storage section 333 to record the information in the viewing information storage section 333 as shown in FIG. In addition to uploading the viewing history information MV to the transmitting device 10 on the broadcast supply side, the contract information storage unit 332 is controlled to read and upload information of a preset upload type. For this reason, the viewing information can be periodically and automatically uploaded.

The viewing information collection processing section 18 of the transmitting device 10 on the broadcast supply side receives the information uploaded from the receiving terminal device 30, and detects a contract information MB when the header indicating the information is the contract information MB. Perform data analysis of Here, when the contract information MA stored in the transmitting device 10 is equal to the uploaded contract information MB, it can be confirmed that the receiving terminal device 30 has correctly received the individual information. When the contract information MA stored in the transmitting device 10 is not equal to the uploaded contract information MB, it is determined that the individual information is not correctly received by the receiving terminal device 30, and the individual information is retransmitted. This allows the broadcast supply side to update the contract information MB in the receiving terminal device 30.

As described above, according to the above-described embodiment,
Since the contract information can be uploaded from the receiving terminal device in response to a request from the broadcast supply side, the management capability of the individual information can be improved by checking the setting state of the contract information in the receiving terminal device. Also,
When it is determined that the contract information is correctly stored in the receiving terminal device, the program can be correctly viewed on the receiving terminal device without transmitting the individual information until the contract information is updated. Need not be transmitted to the receiving terminal device many times, and a broadcast program or the like can be transmitted efficiently.

Since the contract information is uploaded by the operation of the receiving terminal device, the upload operation is performed when the program for which the viewing contract has been made cannot be viewed.
You can check whether the contract information is correctly set. Further, by uploading the contract information together with the viewing history information every time the predetermined period elapses, the broadcast supply side can periodically and automatically check the contract information.

The information uploaded from the receiving terminal device 30 is not limited to the contract information. For example, information for setting the function of the receiving terminal device 30 is included in the individual information and transmitted. If the uploading is performed from the terminal device 30, the function of the receiving terminal device 30 can be set and confirmed by the transmitting device.
