[Prior art]
In recent years, digital television broadcasting has started in Japan and overseas. In digital television broadcasting, many television broadcasts and data broadcasts are transmitted taking advantage of the multi-channel characteristics.
[0003]
Also, in digital broadcasting, there is a mechanism for managing limited viewing according to viewing contracts by using scramble technology and having receiver IDs for each receiver so that EMMs can be individually transmitted from broadcasting companies. Pay TV can be realized relatively easily. A conventional digital broadcast receiver and digital broadcast system will be described below. FIG. 13 shows the configuration of a conventional digital broadcast receiver.
[0004]
In FIG. 13, reference numeral 131 denotes a tuner that receives a digital television broadcast received by an antenna, selects a channel under the control of a microcomputer 135 described later, and performs detection. Reference numeral 132 denotes a user interface for selecting a program desired by the user or operating the GUI with a remote controller.
[0005]
Reference numeral 133 denotes a decoder which inputs a digital broadcast signal selected and detected by the tuner 131, filters the packet corresponding to the program selected by the user after digital demodulation, and is connected by AV decoding for the television broadcast program. The section data such as data broadcasting programs and EMMs are temporarily developed in the memory 134. A microcomputer 135 analyzes a channel selection operation signal from the remote controller 132, and performs channel selection control of the tuner 131 and control for designating a filtering packet of the decoder 133 in accordance therewith.
[0006]
The microcomputer 135 records data indicating the station of the program selected by the user in the channel selection data area of the EEPROM A 136. At reset, the microcomputer 135 reads the data in the channel selection data area of the EEPROM A 136 and controls the tuner 131 to perform channel selection according to the contents.
[0007]
As a result, when the user turns on the power, the user can view the broadcast that was being watched when the power was turned off without operating. Viewing information such as a user's pay broadcast purchase history (represented as viewing history information in the claims) is stored in the EEPROM B 138 in the IC card 137 under the control of the microcomputer 135, and the viewing information is shown in the EMM section. It is transmitted from the modem 139 to the viewing information collection center under the control of the microcomputer 135 in accordance with forced call information described later.
[0008]
The section data of the data broadcast received and selected by the tuner 131 is temporarily expanded in the memory 134 and then transferred to and stored in the HDD (hard disk) 130. When the user wants to view the stored data broadcast, when the user operates the GUI using the remote control 132, the microcomputer 135 analyzes the signal from the remote control 132, reads the necessary data from the HDD 130 according to the content, and stores it in the memory 134. After the data is constructed, it is converted to graphics data or still image data that can be displayed on the decoder and output to the connected television.
[0009]
Next, channel selection control executed by the conventional microcomputer 135 and digital broadcast selection control stored will be described with reference to FIG.
[0010]
As described above, the microcomputer 135 records data indicating the station of the program selected by the user in the channel selection data area of the EEPROM A 136. After reset, the microcomputer 135 reads the data in the channel selection data area of the EEPROM A 136 and controls the tuner 131 to perform channel selection according to the contents (STEP 2).
[0011]
Thereafter, when the user selects a channel using the remote controller 132 (STEP 3), the microcomputer 135 analyzes the operation, controls the tuner 131 to perform channel selection according to the result, and selects the channel data area of the EEPROM A 136. Is updated (STEP 4).
[0012]
Next, a conventional EMM section for transmitting reception contract information will be described with reference to FIG.
[0013]
A decoder identification number is individually assigned to a security module generally used in a receiver. After receiving an EMM packet, the receiver reads out data in a field indicating the decoder identification number in the section and reads the decoder identification number. If the number matches, the receiver determines that the reception contract information is addressed to the user and receives the EMM section.
[0014]
The information contained within that section is mainly shown in FIG.
In FIG. 14, the EMM section header is a header for identifying the EMM section in the section. The decoder identification number is as described above. The paid business entity identification code is a code for identifying a business entity for pay broadcast operation. The update number is a number that increases when the individual information is updated.
[0015]
The expiration date is information on the expiration date of the individual information. The work key is key information necessary for descrambling. The PPV contract information setting is information for pay per view contract information setting. The forced call setting is information for instructing a forced call to transmit the viewing information to the receiver to the viewing information collection center.
[0016]
Next, a conventional data providing method and billing method will be described with reference to FIG.
Reference numeral 161 denotes a user of a digital television receiver. The user contracts with the service entity 162 to receive and view the service data provided by the service entity 162 using a digital television receiver. Reference numeral 163 denotes an EMM transmission entity that sends out the EMM section to all viewing contractors under the commission of the service entity 162.
[0017]
The digital television receiver of the user 161 receives EMM sections having the same decoder identification number from all EMM sections transmitted by the EMM transmission entity 163 and obtains information for generating a descrambling key necessary for viewing.
[0018]
164 is a viewing information collection center that collects viewing information such as pay broadcast purchase history of all viewing contractors under the commission of the service entity 162. The viewing information of the user 161 is transmitted to the viewing information collection center 164 according to the forced call setting information in the EMM section received by the digital receiver being used. The viewing information collection center 164 submits the collected viewing information to the service entity 162. The service entity charges the user 161 as a viewing fee according to the viewing information of the user 161.
[0019]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the invention will be described with reference to the drawings.
[0042]
(Embodiment 1)
Embodiment 1 of the present invention will be described below with reference to the drawings.
In FIG. 1, reference numeral 1 denotes a tuner which receives a digital television broadcast received by an antenna, selects a channel under the control of a microcomputer 5 described later, and performs detection. A remote controller 2 is a user interface for selecting a program desired by the user and operating the GUI.
[0043]
Decoder 3 is a digital broadcast signal selected and detected by tuner 1, digitally demodulated, then filtered service packets set by microcomputer 5, and television broadcast programs are connected by AV decoding. Output to the TV. The section data such as EMM is temporarily developed in the memory 4 under the control of the microcomputer 5 and analyzed.
[0044]
Reference numeral 6 denotes EEPROMA, which indicates data indicating the station selected by the tuner 1 in the channel selection data area, and channel selection fixed setting in the EMM section described later regardless of the user channel selection operation in the channel selection control data area. Data indicating the state of whether or not the channel selection is fixed according to the data is written under the control of the microcomputer 5.
[0045]
At reset, the microcomputer 5 reads the data in the channel selection data area and the channel selection control data area of the EEPROM A 6 and controls the tuner 1 to perform channel selection according to the contents. This control procedure will be described later with reference to FIG. As a result, when the user turns on the power, the user views the broadcast that was being viewed when the power was turned off without operating the broadcast.
[0046]
Note that the microcomputer 5 without the EEPROM 6 fixes the tuning according to the data indicating the station selected by the tuner 1 and the tuning selection setting data in the EMM section described later without depending on the user's tuning operation. In some cases, the tuner 1 performs channel selection according to the initial hardware settings after resetting, without performing control for storing data indicating whether or not the data is present. In that case, when the user turns on the power, the user cannot view the broadcast that was being watched when the power was turned off without operating.
[0047]
Next, the EMM section for transmitting the reception contract information according to the first embodiment will be described with reference to FIG.
[0048]
In general, a decoder identification number is individually assigned to a security module used by a receiver, and after receiving an EMM packet, the receiver reads data in a field indicating the decoder identification number in the section and reads the decoder identification number. If it matches, the receiver determines that the reception contract information is addressed to the user and receives the EMM section. The information contained within that section of the invention is primarily shown in FIG.
In FIG. 2, the EMM section header is a header for identifying the EMM section in the section. The decoder identification number is as described above. The paid business entity identification code is a code for identifying a business entity for pay broadcast operation. The update number is a number that increases when the individual information is updated.
The expiration date is information on the expiration date of the individual information. The work key is key information necessary for descrambling. The PPV contract information setting is information for pay per view contract information setting. The forced call setting is information for instructing a forced call to transmit viewing information to the viewing information collection center to the receiver. The fixed channel selection setting means that the business entity indicated by the paid business entity identification code in the EMM section instructs to set the channel selection so that the service provided to the receiver can always be received.
The channel selection of the receiver here means not only the channel selection of the tuner but also the selection of the service provided by the business entity including the filtering of the decoder. In particular, in the case of a receiver equipped with a storage device such as an HDD or a non-volatile memory, the services provided by the storage entity including the selection of the digital broadcast stored in the storage device by the tuner selection and the filtering of the decoder. It may mean selection.
[0049]
As an example of fixed channel selection, as shown in FIG. 2, for example, when 00h is 1 byte of information, the upper 1 bit is 0, so the tuning of the tuner of the receiver is not fixed and set. In the case of 8Fh, since the upper 1 bit is 1, it is instructed that the tuning of the tuner of the receiver is fixed and set to receive the digital broadcast of the channel indicated by the remaining lower bit 0Fh. .
[0050]
In another example, when 1h information is 00h, the upper 1 bit is 0, so the service provided by the business entity indicated by the paid business entity identification code in the EMM section is not fixedly set to be received. In the case of 88h, since the upper 1 bit is 1, the tuner tuning is fixed to receive the digital broadcast of the channel indicated by the remaining lower bit 08h, and the business indicated by the pay entity identification code In some cases, it may be instructed to fix and set decoder filtering to receive services provided by the body.
[0051]
In another example, in the case of 000000h in the 3-byte information, since the upper 1 bit is 0, it is instructed not to fix the channel selection of the receiver or the filtering of the decoder, and in the case of A20146h, the upper 1 bit. Is fixed to receive the digital broadcast of the channel indicated by 22h of the lower 7 bits of the bit, and further receives the service of the service ID indicated by 146h of the lower 8 bits. Instruct the decoder to set filtering. Note that the tuning fixed setting data included in the EMM packet of the present embodiment may be included in the EMM message packet.
[0052]
Next, the control of the tuner 1 by the microcomputer 5 in the first embodiment will be described with reference to FIG.
[0053]
After receiving the EMM section of the present embodiment described above, the microcomputer 5 reads the tuning selection setting data in the EMM section and determines whether or not the tuning is fixed (STEP 1).
[0054]
If the data indicates fixed tuning, the data in the tuning data area of EEPROM A6 is updated to the tuning data of the tuner indicated in the tuning fixed setting data, and the tuning control data of EEPROM A6 is updated by the user. Regardless of the channel selection operation, the data is updated to data indicating that the channel is fixed to the channel indicated by the data in the channel selection data area (STEP 2).
[0055]
If the data does not indicate that the tuner is fixed, the data in both areas is not updated. Thereafter, after the user performs an operation such as turning off the power and resets (STEP 3), the microcomputer 5 reads the data in the tuning data area of the EEPROM A 6 and sets the tuning according to the contents (STEP 4). After that, when the user performs a channel selection operation with the remote controller (STEP 5), the microcomputer 5 reads the data in the channel selection control data area of the EEPROM 6 and performs the channel selection indicated by the data in the channel selection data area regardless of the user's channel selection operation. It is determined whether the data indicates what to do (STEP 6).
[0056]
If it is data indicating that the channel selection indicated by the data in the channel selection data area is performed regardless of the user channel selection operation, the user channel selection operation is invalidated for the tuner 1 channel selection. The tuning of the tuner 1 is controlled according to the tuning operation, and the data in the tuning data area of the EEPROM 6 is also updated (STEP 7).
[0057]
It should be noted that a plurality of tuners in the present invention may be provided, and a tuning data area and a tuning control data area corresponding to each may be provided, and different tuning control may be performed on each tuner.
[0058]
Alternatively, tuning selection control data corresponding to the tuning selection setting data may be performed without waiting for a reset after reading the tuning selection setting data in the EMM section and determining whether the tuner selection is fixed. Further, as the channel selection fixed setting, the tuner channel selection may be fixed and set according to the channel selection data indicated in the channel selection fixed setting data, or the entity indicated by the pay entity identification code in the EMM section. The tuning of the tuner and the filtering of the decoder may be fixed so as to receive the service provided by the tuner, and the tuning of the tuner may be selected according to the tuning data and the service ID indicated in the tuning fixed setting data. Decoder filtering may be fixedly set.
By reading the tuning fixed setting data in the received EMM section and performing tuning control according to the contents of the received data, the service provider can always receive the service provided using digital broadcasting. The EMM section that is transmitted including data for setting the channel selection of the tuner so that it is difficult to set and maintain the channel selection, and the digital broadcasting service provided by the service entity can always be received Or the problem that the digital broadcast receiver which receives the EMM message section and sets the tuning of the tuner cannot be realized is solved.

It is determined whether or not (STEP 1).
[0101]
When the channel selection control is fixed, data indicating that the channel selection control is stored in the storage fixed data area of the HDD 80 is written in association with the data stored by the service. Otherwise, data indicating that the channel selection control has been stored by a tuner that is not fixed is written in association with the data stored by the service (STEP 2).
[0102]
The association can be easily realized by writing to the address associated with the address of the area in which the accumulated data of the accumulated services is stored, or by matching the order of storing the accumulated services.

Thereafter, when the user views the stored service (STEP 3), the microcomputer 85 reads the data in the stored fixed data area corresponding to the stored service being viewed, and uses it as the tuning fixed setting data in the EMM section. Accordingly, it is determined whether or not the channel selection control is stored in a fixed state (STEP 4).
[0104]
When the channel selection control is fixed, data indicating that the user has viewed with a tuner whose channel selection control is fixed is written in the channel selection fixed data area of the EEPROM B 88 in association with the viewing information of the service. Otherwise, data indicating that the user has viewed with a tuner whose channel selection control is not fixed is written in association with the viewing information of the service (STEP 5).
[0105]
The association can be easily realized by writing to the address associated with the address of the area where viewing information of the viewed service is stored or matching the order of storing the viewing information of the service. The viewing information and tuning fixed data are transmitted from the modem 89 to the viewing information collection center under the control of the microcomputer 85 according to the forced call information described later shown in the EMM section (STEP 6).
[0106]
In the present invention, three or more tuners may be provided, and corresponding tuning data areas and tuning control data areas may be provided, and different tuning controls may be performed on the respective tuners. Also, the tuning fixed data area may be prepared outside the IC card and associated with the viewing information when the modem 49 transmits.

[0135]
(Embodiment 8)
Embodiment 8 of the present invention will be described below with reference to the drawings.
The configuration is the same as in the fourth embodiment. However, in the channel selection control data area of EEPROM A86 in the description of the configuration of the fourth embodiment, data indicating the status of each tuner is written to indicate whether the channel selection is fixed according to the operation of remote controller 82. ing.
[0136]
Further, in the storage fixed data area of the HDD 80, data indicating the state of whether or not the selection of the service stored in the HDD 80 is fixed according to the operation of the remote controller 82 is written. In the channel selection fixed data area of EEPROM B88, data indicating whether or not the user has viewed with a tuner with fixed channel selection is written under the same control as in the fourth embodiment.
[0137]
The control of tuners 81 and 807 by microcomputer 85 of the eighth embodiment will be described with reference to FIG.
When the user operates the remote controller 81 to fix the tuner selection to the broadcasting station of the service provided by the specific business entity, the microcomputer 85 recognizes the user's tuning selection operation (STEP 1). Next, all channel selection control data of the EEPROMA 86 is read (STEP 2).
[0138]
The read data is analyzed to determine whether or not the channel selection is fixed (STEP 3). When the tuner 81 is not fixed and selected, the data in the channel selection data area of the EEPROM 66 corresponding to the tuner 81 is updated to the channel selection data of the tuner that receives the broadcast of the business entity operated and instructed by the user. The channel selection control data in the EEPROMA 86 is updated to data indicating that the channel selection indicated by the data in the channel selection data area is performed regardless of the user channel selection operation (STEP 4).
[0139]
In this case, it is possible to prepare a table of information such as the buttons of the remote controller 82, the broadcasting station of the service provided by the business entity, and the service ID. Thereafter, after the user performs an operation such as turning off the power and resets (STEP 5), the microcomputer 85 reads all data in the tuning data area of the EEPROM A 86 and controls the tuning according to the contents of each tuner (STEP 6). ).
[0140]
After that, the microcomputer 85 sets a service ID so as to filter the data broadcasting service of the business entity operated and instructed by the user using the remote controller 82 among the digital broadcasts received by the tuner 81 that is fixedly selected. The decoder 83 filters the data broadcasting service of the business entity, develops it on the memory 84, and sequentially stores it in the HDD 80 (STEP 7).
[0141]
When the user performs a channel selection operation with the remote controller (STEP 8), the microcomputer 85 reads all data in the channel selection control data area of the EEPROMA 86 and corresponds to data indicating that the channel selection is performed according to the user channel selection operation. The tuner 807 is used to control the channel selection according to the user's channel selection operation, and the corresponding data in the channel selection data area of the EEPROMA 86 is also updated (STEP 9).
[0142]
Next, channel selection fixed data area writing of EEPROM B 88, viewing information transmission, and storage fixed data writing control of HDD 80 by microcomputer 85 in the eighth embodiment will be described with reference to FIG. When the service is stored in the HDD 80, the microcomputer 85 reads the data in the channel selection control data area corresponding to the received tuner and determines whether or not the channel selection control is fixed (STEP 1).
[0143]
When the channel selection control is fixed, data indicating that the channel selection control is stored in the storage fixed data area of the HDD 80 is written in association with the data stored by the service. If not, the data indicating that it has been stored by a tuner whose channel selection control is not fixed is written in association with the data stored by the service (STEP 2).
[0144]
The association can be easily realized by writing to the address associated with the address of the area storing the accumulated data of the accumulated services, or by matching the order of storing the accumulated services. Thereafter, when the user views the stored service (STEP 3), the microcomputer 85 reads the data in the stored fixed data area corresponding to the stored service being viewed and the channel selection control is fixed. (STEP 4).
[0145]
When the channel selection control is fixed, data indicating that the tuner is fixed to the channel selection control in the channel selection fixed data area of the EEPROM B88 is written in association with the viewing information of the service. Otherwise, data indicating that the user has viewed with a tuner whose channel selection control is not fixed is written in association with the viewing information of the service (STEP 5).
[0146]
The association can be easily realized by writing in the address associated with the address of the area where viewing information of the viewed service is stored, or matching the order of storing the viewing information of the service. The viewing information and the fixed channel selection data are transmitted from the modem 89 to the viewing information collection center under the control of the microcomputer 85 according to the above-mentioned forced call information shown in the EMM section (STEP 6).
[0147]
In the present invention, three or more tuners may be provided, a corresponding channel selection data region and channel selection control data region may be provided, and different channel selection control may be performed for each tuner.
[0148]
It is also possible to determine the order in which the tuning is fixed in advance among a plurality of tuners. In addition, a tuner to be fixed and fixed among a plurality of tuners is determined in advance, and after receiving the fixed tuning setting data, the tuners to be fixed that are determined in advance without referring to the tuning control data of all the tuners. You may control to update channel selection data and channel selection control data.
[0149]
In that case, it may be controlled to use a tuner other than the predetermined fixed tuner without referring to the tuning control data of all tuners for the tuning operation of the user. Also, the tuning fixed data area may be prepared outside the IC card and associated with the viewing information when the modem 49 transmits.
[0150]
In addition, when the user decides the tuning selection operation or sets the tuning selection release, a password issued by a specific business entity or manufacturer may be input. Further, the screen data for performing the fixed channel operation may be obtained from the business in advance before the user determines the fixed channel operation.
