Description

  The present disclosure relates to a signal processing apparatus that can use a plurality of descramble processing cards (for example, B-CAS cards) that can conclude a pay broadcast contract and perform data descrambling processing using the cards.

  Patent Document 1 discloses a program recording / reproducing apparatus. This program recording / playback apparatus includes three tuners. This program recording / playback apparatus records programs received simultaneously by three tuners on a hard disk.

  Generally, when a received program is descrambled, a B-CAS card (B-CAS: registered trademark) is required. The B-CAS card is an IC card issued by B-CAS and is used for descrambling broadcast programs. There is a limit to the number of programs that can be descrambled with one B-CAS card. For example, it is restricted that one B-CAS card can process up to three programs.

  In the program recording / reproducing apparatus disclosed in Patent Document 1, three programs are received simultaneously. Therefore, in this case, the descrambling process for all broadcast programs received at the same time can be executed by using only one B-CAS card.

  One program recording / playback apparatus may be able to simultaneously receive more programs than can be processed simultaneously by one B-CAS card. In this case, in the program recording / playback apparatus, a plurality of B-CAS cards are required for the descrambling process.

  Further, it is necessary to make a contract with a broadcaster regarding pay broadcasting for each B-CAS card.

1. Embodiment 1
Hereinafter, Embodiment 1 in which the idea of the present disclosure is applied to a BD recorder will be described with reference to the drawings.

1-1. An outline of the outline BD recorder will be described with reference to FIG. FIG. 1 is an external perspective view of the BD recorder 100. The BD recorder 100 can record a broadcast program. The BD recorder 100 has 12 tuners. The BD recorder 100 uses 9 of the 12 tuners for time-shift recording, and 3 tuners for normal recording or viewing.

  Here, “time shift recording” means that a program broadcast on a channel selected by the user is constantly received via the tuner, and program data generated based on the received program is always recorded on the internal hard disk. It is a recording method. When performing time shift recording, the BD recorder 100 always stores program data for a certain period (for example, one week) on the hard disk with respect to a program broadcast on the channel selected by the user. If the capacity exceeds a certain period, the BD recorder 100 deletes old program data of the same channel.

  On the other hand, “normal recording” is a recording method in which a program selected by a user is received via a tuner and program data generated based on the received program is recorded on an internal hard disk. Normal recording includes reserved recording and recording of a currently broadcast program. With reserved recording, a user makes a reservation for recording of a program to be broadcast in the future, and when the reserved date and time comes, the BD recorder 100 automatically receives the reserved program and sets the received program as the received program. This is a recording method in which program data generated based on this is automatically recorded on a hard disk.

  The program data generated by receiving the broadcast by the tuner is the program data before descrambling. The program data before descrambling is in an encrypted state. Even if the user visually recognizes the program data before the descrambling process, the user cannot recognize the program content. Therefore, the BD recorder 100 needs to perform descrambling processing on the program data before descrambling processing. The descrambling process requires a B-CAS card. The number of program data that can be descrambled simultaneously by one B-CAS card is limited. In the present embodiment, it is assumed that descrambling processing can be simultaneously performed on program data for three channels by using one B-CAS card. The BD recorder 100 of this embodiment uses four B-CAS cards in order to process program data for 12 channels from 12 tuners.

  By the way, among broadcast programs, there is a pay program that can be viewed when a user individually contracts with a broadcaster. It is necessary to conclude a contract with a broadcaster for viewing this pay program for each B-CAS card. In other words, in a device that uses four B-CAS cards, when it is desired to view pay broadcasts with all tuners, it is necessary to conclude a pay broadcast contract for up to four with the broadcaster. On the other hand, if it is considered that it is only necessary to view paid broadcasts with some tuners, it is only necessary to conclude a paid broadcast contract with a broadcaster for only some B-CAS cards.

  When the user has concluded a pay broadcast contract only for a part of the B-CAS cards, the B-CAS card that has concluded the pay broadcast contract and the B-CAS card that has not concluded the pay broadcast contract are the devices. Will be mixed. In such a case, the user may be confused as to which B-CAS card has a pay broadcast contract and which B-CAS card has not a pay broadcast contract. When a pay-broadcast time-shift recording setting or a reserved recording setting is made for a tuner that supports a B-CAS card that does not conclude a pay-broadcasting contract, the user wanted to record. A situation may occur where the program is not recorded.

  In addition, a free viewing period for pay broadcasting is set for the B-CAS card. As described above, the BD recorder 100 includes four B-CAS cards. It is assumed that the user uses the first B-CAS card, enjoys pay broadcasting within the free viewing period of the pay broadcast, and the free viewing period of the first B-CAS card expires. Next, it is assumed that the user uses the second B-CAS card and enjoys pay broadcasting during the pay broadcasting free viewing period. In this case, the pay broadcast free viewing period for the B-CAS card is substantially extended against the intention of the broadcaster. Such a situation is undesirable for pay broadcasters.

  As described above, various problems may occur in a signal processing apparatus that uses a plurality of B-CAS cards that can conclude a pay broadcast contract.

  The BD recorder 100 incorporates structural ingenuity in order to solve at least a part of problems that may occur in a signal processing apparatus that can use a plurality of B-CAS cards that can conclude a pay broadcast contract. This configuration device will be described in detail below.

1-2. External Configuration An external configuration of the BD recorder 100 will be described with reference to FIGS. FIG. 2 is a schematic external view showing the back surface of the BD recorder 100. As shown in FIG. 1, the BD recorder 100 has a BD drive 110 and a B-CAS card slot 120 on the front side. As shown in FIG. 2, the BD recorder 100 has a B-CAS card slot 130, a B-CAS card slot 140, a B-CAS card slot 150, and a terrestrial digital antenna mounting portion 121-BS / CS antenna on the back side. A mounting portion 152 is provided.

  Here, the B-CAS card corresponding to each of the B-CAS card slot 120, the B-CAS card slot 130, the B-CAS card slot 140, and the B-CAS card slot 150 will be described.

  A B-CAS card slot 120 provided on the front surface of the BD recorder 100 corresponds to a shared B-CAS card (red) which is a B-CAS card corresponding to BS, CS, and terrestrial digital broadcasting. The shared B-CAS card inserted into the B-CAS card slot 120 is used for normal recording or viewing. In the received data broadcast, the card ID of the B-CAS card to be displayed is performed by using a shared B-CAS card inserted in the B-CAS card slot 120 in principle. Another name for the shared B-CAS card is referred to as a “representative card”. The reason for configuring in this way will be described.

  It is assumed that it is not specified which B-CAS card ID is displayed in data broadcasting. In addition, there are broadcasts that allow users to enjoy games. When starting this game, the user may need to input the card ID of the B-CAS card into the device. In such game data broadcasting, game points are added in association with card IDs. In such a case, if a card ID of a different B-CAS card is displayed every time the user inputs a card ID of the B-CAS card, a different B-CAS card is used each time the user starts a game. There is a risk of entering the card ID. When such a situation occurs, although the user plays the same game every time, game points are distributed and added to a plurality of card IDs. Therefore, in the BD recorder 100 of the present embodiment, such a situation is avoided by using the card ID displayed in the data broadcast as the card ID of the representative card.

  A B-CAS card slot 130 provided on the back surface of the BD recorder 100 is a B-CAS card that supports BS, CS, and terrestrial digital broadcasting, but has a smaller size than a shared B-CAS card. -Corresponds to CAS card (red). For this reason, the B-CAS card slot 130 is smaller in size than the B-CAS card slot 120. Further, the other B-CAS card slots 140 and 150 provided on the back of the BD recorder 100 are B-CAS cards that are compatible only with terrestrial digital broadcasting, and are mini terrestrial digital cameras that are smaller in size than the common B-CAS card. It corresponds to a dedicated B-CAS card (blue). The B-CAS card slots 130 to 150 are used for time shift recording. The B-CAS card slots 130 to 150 are configured to be smaller than the B-CAS card slot 120 because the size of the card to be handled is small.

  As described above, in the BD recorder 100 according to the present embodiment, the slot for the B-CAS card for normal recording or viewing is arranged on the front side of the device, and the slot for the B-CAS card for time shift recording on the back side. Is arranged. Therefore, when a pay broadcast contract is concluded with a B-CAS card for normal recording or viewing, the B-CAS card inserted into the slot on the front side of the device signs a pay broadcast contract. The user can easily recognize that the card is a B-CAS card.

  Even when the B-CAS card for time-shift recording has a pay broadcast contract, the BD recorder 100 uses the mini-shared B-CAS card (of the B-CAS cards for time-shift recording) ( (Red) is only one card (the other two B-CAS cards are mini terrestrial digital B-CAS cards (blue)), and the B-CAS card inserted in the slot on the back side of the device The user can easily recognize which B-CAS card has a pay broadcast contract.

  The BD recorder 100 is different in size between the B-CAS card inserted into the front side of the device and the B-CAS card inserted into the back side of the device. As a result, when the user recognizes that the pay broadcast contract has been concluded for the B-CAS card for normal recording or viewing without the B-CAS card being inserted into the BD recorder 100 yet. By simply looking at the size of the B-CAS card, the user can recognize that the larger shared B-CAS card is a B-CAS card with a pay broadcast contract. On the other hand, if the B-CAS card has not yet been inserted into the BD recorder 100 and the user recognizes that a pay broadcast contract has been concluded for the B-CAS card for time-shift recording, it is used. The person can recognize that the smaller shared B-CAS card is a B-CAS card that has signed a pay broadcast contract only by looking at the size of the B-CAS card.

1-3. Electrical Configuration The electrical configuration of the BD recorder 100 will be described with reference to FIG. FIG. 3 is a block diagram showing an electrical configuration of the BD recorder 100. The BD recorder 100 includes a block used for normal recording or viewing and a block used for time-shift recording. First, blocks used for normal recording or viewing will be described.

1-3-1. Configuration of Normal Recording / Viewing Blocks Blocks used for normal recording or viewing include tuners 123 to 125. The tuner 123, the tuner 124, and the tuner 125 extract the radio wave of the channel selected by the user from the radio waves received via the terrestrial digital broadcast antenna or the BS / CS broadcast antenna. The tuner 123, the tuner 124, and the tuner 125 generate program data before descrambling processing based on the extracted radio wave. Further, the tuner 123, the tuner 124, and the tuner 125 receive the data broadcast, and generate a data broadcast screen based on the received data broadcast.

  The descrambler 126 performs descrambling on the program data before descrambling using the shared B-CAS card inserted into the B-CAS card slot 120.

  The LSI 170 is a control unit that controls blocks used for normal recording or viewing. The LSI 170 performs image processing such as encoding processing and decoding processing on the program data that has been descrambled by the descrambler 126. The LSI 170 records the encoded program data in the HDD 160, or performs decoding processing on the encoded program data stored in the HDD 160, the BD drive 110, or the HDD 180, and converts the decoded program data into the HDMI 220. Or output.

  The HDD 160 is a storage device that stores moving image data and the like. The BD drive 110 is a drive that records data on the BD and reads data stored on the BD.

  The above is the block used for normal recording or viewing. Next, blocks used for time shift recording will be described.

1-3-2 Configuration of Time Shift Recording Blocks Blocks used for time shift recording include tuners 133 to 135. The tuner 133, the tuner 134, and the tuner 135 extract the radio wave of the channel selected by the user from the radio waves received via the terrestrial digital broadcast antenna or the BS / CS broadcast antenna. The tuner 133, the tuner 134, and the tuner 135 generate program data before descrambling processing based on the extracted radio waves.

  The descrambler 136 performs a descrambling process on the program data before the descrambling process, using the mini shared B-CAS card inserted into the B-CAS card slot 130.

  The LSI 190 is a control unit that controls blocks that process program data generated via the tuner 133, the tuner 134, and the tuner 135 among the blocks used for time shift recording. The LSI 190 continuously records program data generated on the basis of the program of the channel instructed by the user for time-shift recording on the HDD 180. When the program length of a specific channel stored in the HDD 180 exceeds a predetermined period, the LSI 190 erases the program data of the old program of the same channel from the HDD 180. The LSI 190 monitors the length of program data of a specific channel stored in the HDD 180 so as not to exceed a predetermined period.

  The blocks used for time shift recording further include tuners 143 to 155. The tuner 143, the tuner 144, the tuner 145, the tuner 153, the tuner 154, and the tuner 155 generate program data before descrambling processing based on the extracted radio waves.

  The descrambler 146 and the descrambler 156 use the mini terrestrial digital B-CAS card inserted in the B-CAS card slot 140 and the B-CAS card slot 150 to process program data before descrambling. Apply descrambling.

  The LSI 200 and the LSI 210 control blocks for processing program data generated via the tuner 143, the tuner 144, the tuner 145, the tuner 153, the tuner 154, and the tuner 155 among the blocks used for time shift recording. It is a control unit. The LSI 200 and the LSI 210 record the encoded program data to the HDD 180 in the same manner as the LSI 190. Similar to LSI 190, LSI 200 and LSI 210 monitor the length of program data of a specific channel stored in HDD 180 so as not to exceed a predetermined period.

  The HDD 180 is a storage device that stores moving image data and the like.

  The above is the block used for time shift recording.

  The user can give various instructions to the BD recorder 100 via an operation button or the like provided on the remote controller 400 or the BD recorder main body. For this reason, the BD recorder 100 includes a remote control receiving unit 250 that receives an instruction from the remote control 400. The remote control receiving unit 250 transmits a control signal corresponding to the received instruction to the LSI 170.

  B-CAS card slots 120 and 130 shown in this embodiment and the following embodiments are examples of first and second BS card slots. The configuration of the combination of the descramblers 126 and 136 is an example of a decoding processing unit. The configuration of the combination of the LSI 170 and the HDMI 220 is an example of an output unit. The remote control receiving unit 250 is an example of a receiving unit.

1-4. Operation Next, various operations of the BD recorder 100 will be described with reference to the drawings.

1-4-1. Initial setting operation (default setting operation)
An initial setting operation (purchase setting operation) of the BD recorder 100 will be described with reference to FIGS. Here, the initial setting operation (purchase setting operation) is an operation of the BD recorder 100 when the user first turns on the power after purchasing the BD recorder 100. FIG. 4 is a flowchart for explaining the initial setting operation of the BD recorder 100. 5 to 9 are schematic diagrams showing display screens when the BD recorder 100 is initially set.

  When the power is first turned on by the user, the BD recorder 100 starts an initial setting operation (purchase setting operation) (S200). When settings such as remote control setting and antenna setting are executed, the BD recorder 100 outputs image data of a screen prompting the user to insert a shared B-CAS card in front of the main body as shown in FIG. S210). When the image data of the screen as shown in FIG. 5 is output, the LSI 170 determines whether an instruction to proceed to the next screen by the operation of the remote controller 400 is received via the remote control receiving unit 250 (S220). If it is determined that an instruction to proceed to the next screen has been received, the LSI 170 determines whether a shared B-CAS card is inserted in the B-CAS card slot 120 (S230). Specifically, the LSI 170 determines the connection itself of the B-CAS card based on the presence or absence of electrical connection. Further, the LSI 170 determines whether the inserted B-CAS card is a shared B-CAS card or a terrestrial digital B-CAS card based on the card ID of the B-CAS card. The card ID of the B-CAS card is assigned so that the shared B-CAS card and the terrestrial digital dedicated B-CAS card can be distinguished.

  If it is determined that the shared B-CAS card is not inserted, the BD recorder 100 outputs image data of a screen warning that no shared B-CAS card is inserted on the front surface of the main body as shown in FIG. (S240). When the warning screen image data is output, the LSI 170 determines whether an instruction to proceed to the next screen has been received from the user (S250). If it is determined that an instruction to proceed to the next screen has been received, the LSI 170 returns to step S230 and determines whether a shared B-CAS card is inserted in the B-CAS card slot 120.

  If it is determined in step S230 that the shared B-CAS card is inserted, the BD recorder 100 has a mini shared B-CAS card and a mini terrestrial digital B-CAS card on the back of the main body as shown in FIG. The image data of the screen prompting the user to insert “and” is output (S260).

  When the image data of the screen as shown in FIG. 7 is output, the LSI 170 determines whether an instruction to proceed to the next screen has been received from the user (S270). If it is determined that an instruction to proceed to the next screen has been received, the LSI 170 determines whether the correct B-CAS card has been inserted into all of the B-CAS card slot 130, the B-CAS card slot 140, and the B-CAS card slot 150. (S280).

  If it is determined that the correct B-CAS card is not inserted into any B-CAS card slot, the BD recorder 100, as shown in FIG. 7B, “The correct B-CAS card is not inserted into the back of the main body. Is output (S290). This screen is a screen that shows which B-CAS card slot has no B-CAS card inserted among the three B-CAS card slots on the back of the main body. For example, the B-CAS card slot in which the B-CAS card is inserted may be colored differently from the B-CAS card slot in which the B-CAS card is not inserted. The cursor may be attached only to the B-CAS card slot that is not inserted.

  When the image data of the warning screen is output in step S290, the LSI 170 determines whether an instruction to proceed to the next screen has been received from the user (S300). If it is determined that an instruction to proceed to the next screen has been received, the process proceeds to step S280, where the LSI 170 inserts the correct B-CAS card into all of the B-CAS card slot 130, B-CAS card slot 140, and B-CAS card slot 150. Judge whether it has been.

  If it is determined in step S280 that correct B-CAS cards are inserted in all B-CAS card slots, the BD recorder 100 indicates the state of each B-CAS card as shown in FIG. 8 or FIG. The screen image data is output (S300).

  Note that the BD recorder 100 switches the type of the B-CAS card indicating the state on the screen when the user presses the left and right keys of the remote control 400 while outputting the image data of this screen. For example, the BD recorder 100 switches the output of the image data so that the screens shown in FIGS. 8 and 9 are displayed. In these screens, it is possible to know which B-CAS card currently being displayed is related to the B-CAS card inserted in which B-CAS card slot. In FIG. 8 and FIG. 9, the B-CAS card slot into which the B-CAS card whose state is currently displayed is inserted is hatched.

  As described above, in the BD recorder 100 according to the present embodiment, in the initial setting, the correct B-CAS card is inserted into the B-CAS card slot on the front surface of the main body, and the B-CAS card slot on the rear surface of the main body is not inserted. A screen prompting the user to insert the B-CAS card is output. As a result, the BD recorder 100 can surely cause the user to insert the correct B-CAS card into the B-CAS card slot.

1-4-2. Time-shift recording reservation operation
1-4-2-1. Pre-processing Operation The pre-processing of time shift recording reservation in the BD recorder 100 will be described with reference to FIG. FIG. 10 is a flowchart for explaining the pre-processing operation of the time shift recording reservation.

  The time shift recording reservation pre-processing is executed at the time of initial setting (purchase setting) of the BD recorder 100. The BD recorder 100 prompts the user to set a time shift recording reservation during initial setting (purchase setting). Before outputting a screen that prompts the user to set the time-shift recording reservation (S400), the LSI 170 uses a mini-shared B-CAS card inserted into the B-CAS card slot 130 in the background to charge a fee. A channel descrambling process is executed (S410). This descrambling process of the pay channel is executed for each pay channel by sequentially switching each pay channel in the mini shared B-CAS card inserted in the B-CAS card slot 130.

  Thereafter, the BD recorder 100 sets a default channel for each tuner (tuner 123 to tuner 155) on a screen prompting the user to set a time-shift recording reservation (S420). As a default channel, a terrestrial digital broadcast channel is set preferentially, and a BS digital or CS channel is set for an empty tuner.

  As described above, the BD recorder 100 according to the present embodiment automatically receives a pay program broadcast on a pay channel at the time of initial setting, and performs descrambling processing on the received pay program in the B-CAS card slot 130. Execute using the inserted mini shared B-CAS card. Thereby, the free viewing period of the pay broadcast of the mini shared B-CAS card inserted into the B-CAS card slot 130 automatically starts. As a result, it is possible to solve the problem that the free viewing period is substantially extended by sequentially using the free viewing periods of the plurality of shared B-CAS cards.

1-4-2-2. Time Shift Recording Reservation Operation The operation of time shift recording reservation in the BD recorder 100 will be described with reference to FIGS. FIG. 11 is a flowchart showing a time shift recording reservation operation in the BD recorder 100. FIG. 12 is a diagram showing a reservation screen (setting menu) for setting a target channel for time-shift recording. 13 and 14 are diagrams showing a detailed setting screen related to the target channel selected on the reservation screen (setting menu). FIG. 15 is a diagram showing a screen for inquiring a user about a pay broadcast contract.

  When receiving a setting menu display instruction for setting a target channel for time-shift recording from the user, the BD recorder 100 displays image data of a setting menu screen as shown in FIG. It outputs to 300 (S100). In FIG. 12, channel 1 to channel 3 correspond to channels received by tuners 133 to 135, respectively. Channels 4 to 6 correspond to channels received by the tuners 143 to 145. Channels 7 to 9 correspond to channels received by the tuners 153 to 155. The user can select a channel for setting time-shift recording on the setting menu shown in FIG. 12 by moving the cursor 310 by operating the cross key on the remote controller 400.

  When the setting menu is displayed (S100 in the flowchart of FIG. 11), the BD recorder 100 waits until receiving a selection of a channel for setting time-shift recording from the user (S110). When the selection of the channel for setting the time shift recording (channel 1 to channel 3) is received, the BD recorder 100 displays a detailed setting screen (screen as shown in FIG. 13 or FIG. 14) regarding the selected channel. (S120).

  The detailed setting screen shown in FIGS. 13 and 14 includes reception confirmation screens 320 and 330. On the reception confirmation screens 320 and 330, an image obtained by descrambling the descrambler 136 using the B-CAS card inserted in the B-CAS card slot 130 is output. That is, the BD recorder 100 receives the broadcast of the channel selected as the time shift recording candidate on the setting menu via the tuner 133. In the BD recorder 100, the descrambler 136 uses the B-CAS card in which the descrambler 136 is inserted in the B-CAS card slot 130 for the descramble process. Therefore, when a pay channel is selected as a channel for time shift recording, a B-CAS card inserted in the B-CAS card slot 130 has a contract for the pay broadcast. As shown in FIG. 13, the reception confirmation screen 320 displays an image of the descrambled program. On the other hand, when the B-CAS card inserted in the B-CAS card slot 130 has not signed the pay broadcast contract, the reception confirmation screen 330 has a data broadcast guide screen as shown in FIG. Is displayed. That is, the reception confirmation screen 330 displays a screen 331 that prompts the user to make a pay broadcast contract.

  When the detailed setting screen is displayed in step S120, the BD recorder 100 determines whether or not the blue button provided on the remote control 400 is pressed by the user (S130). If it is determined that the button has not been pressed, the BD recorder 100 determines whether the enter button has been pressed (S140). If it is determined that the determination button has been pressed, the BD recorder 100 outputs the setting menu image data shown in FIG.

  On the other hand, if it is determined in step S130 that the blue button has been pressed, the BD recorder 100 outputs the image data of the enlarged screens of the reception confirmation screens 320 and 330 (S150). For example, image data of an enlarged screen as shown in FIG. 15 is output. FIG. 15 shows, as an example, a display example when the B-CAS card inserted into the B-CAS card slot 130 has not signed a pay broadcast contract, that is, an enlarged screen of the reception confirmation screen 330. ing. Here, the screen of FIG. 15 shows a guidance screen (CA alternative screen) that guides switching to a data broadcasting guidance channel. Further, the screen of FIG. 15 is displayed with a frame 340 added to the guidance screen for data broadcasting in order to make the user recognize that it is a viewing confirmation screen in time-shift recording, in distinction from the normal viewing screen. doing.

  When the enlarged screen of the reception confirmation screen is output in step S150, the BD recorder 100 determines whether there is an instruction to display the pay broadcast contract screen from the user (S160). The user can issue a pay broadcast contract screen display instruction (select “Yes”) by using the remote controller 400 while the screen as shown in FIG. 15 is displayed.

  When the display instruction of the pay broadcast contract screen is given by the user, the BD recorder 100 outputs image data of the pay broadcast contract screen (data broadcast) (S170). Specifically, the BD recorder 100 outputs image data of a pay broadcast contract screen as shown in FIG. Here, the screen shown in FIG. 16 can also be referred to as a screen (guidance screen) for presenting the user with pay broadcasting guidance regarding the B-CAS card. The BD recorder 100 displays information on the card ID of the B-CAS card inserted in the B-CAS card slot 130 on the pay broadcast contract screen. As described above, the card ID displayed in data broadcasting is usually the card ID of a representative card (B-CAS card inserted in the B-CAS card slot 120). However, in the case of this example, the B-CAS card to conclude a pay broadcast contract is inserted into the B-CAS card slot 130, not the B-CAS card (representative card) inserted into the B-CAS card slot 120. B-CAS card. Accordingly, the card ID of the B-CAS card inserted in the B-CAS card slot 130 is used in the data broadcast display screen for the pay broadcast contract. As a result, the user is prompted to make a pay broadcast contract for the B-CAS card inserted in the B-CAS card slot 130.

  As described above, the BD recorder 100 according to the present embodiment includes an image that has been descrambled by the descrambler 136 with respect to a channel selected as a recording reservation candidate on the reservation setting screen in time-shift recording. It was decided to output the screen. Thereby, even if the B-CAS card inserted in the B-CAS card slot 130 does not conclude a pay broadcast contract, the user selects a pay channel as a target of time shift recording. At this time, it can be known that the pay channel cannot be descrambled depending on the B-CAS card inserted into the B-CAS card slot 130.

  In the BD recorder 100 according to the present embodiment, the card ID displayed in the data broadcast is basically the card ID of the representative card (the shared B-CAS card inserted into the B-CAS card slot 120). I decided to do it. However, in the data broadcasting of the pay broadcast contract for another card other than the representative card, the card ID of the other card is displayed (in other words, the guide screen for presenting the pay broadcast guide to the user) In FIG. 16 (for example, FIG. 16), the card ID of the B-CAS card for which the contract for the pay broadcast is to be concluded is displayed. On the screen other than the guidance screen, the card ID of the predetermined representative card is displayed. indicate.). Thereby, based on the instruction | indication of data broadcasting, a pay broadcast contract with respect to B-CAS cards other than a representative card can be prompted to a user. The user can make a call with a pay broadcaster while viewing the screen as shown in FIG. Thereby, the user can easily convey the card ID of the B-CAS card for which a pay broadcast contract is to be concluded to the broadcast partner of the telephone partner. By knowing the card ID of the correct B-CAS card, the broadcaster can conclude a pay broadcast contract for the correct B-CAS card.

  In the above, the operation for guiding to a screen for performing a pay broadcast contract during the setting of time shift recording has been described. However, for the operation for guiding to a screen for performing a pay broadcast contract during normal broadcast viewing, This will be described later in Section 1-4-11.

1-4-3. B-CAS Card Switching Operation During Viewing A B-CAS card switching operation in the BD recorder 100 will be described with reference to FIG. The BD recorder 100 normally uses a shared B-CAS card inserted in the front B-CAS card slot 120 when viewing a program. When the program data is descrambled using the shared B-CAS card (S500), the LSI 170 instructs the user to switch the B-CAS card used for the descrambling process via the remote controller 400. It is determined whether or not there is (S510). If it is determined that there has been a switching instruction, the LSI 170 uses a B-CAS card inserted in a B-CAS card slot other than the B-CAS card slot 120 to execute a program data descrambling process. Here, as shown in FIG. 15, a frame 340 is added to an image obtained by executing descrambling processing using a B-CAS card inserted in a B-CAS card slot other than the B-CAS card slot 120. It is displayed in the state that was done.

  As described above, the BD recorder 100 according to the present embodiment outputs the data after descrambling by the B-CAS card inserted into the B-CAS card slot 120 based on an instruction from the user. Whether to output data after descrambling processing by a B-CAS card inserted into a card slot other than the B-CAS card slot 120 can be switched. That is, the B-CAS card used when the descrambling process is performed on the program data can be changed based on an instruction from the user. Thereby, the user can confirm which channel can be received by each B-CAS card.

  Further, the BD recorder 100 according to the present embodiment has a B-CAS card inserted in a B-CAS card slot (time shift recording slot) other than the B-CAS card slot 120 (normal viewing / recording slot). When the descrambling process is performed using, a frame 340 is given to the program that has been descrambled (see FIG. 15). Thereby, the user can recognize that the B-CAS card for time shift recording is used for the descrambling process, not the B-CAS card used for the descrambling process in normal viewing / normal recording.

1-4-4. Energization Control Operation The energization control operation of the BD recorder 100 will be described. First, energization control information referred to in the energization control operation will be described. The energization control information is information necessary for renewing a pay broadcast contract. When the contract period of the pay broadcast expires, the BD recorder 100 cannot perform the pay broadcast descrambling process. When the pay broadcast contract is renewed, the BD recorder 100 can acquire information for descrambling the pay broadcast via the broadcast wave. Therefore, the BD recorder 100 needs to be activated during a period in which information for descrambling pay broadcasting is broadcast. Information indicating the period during which information for descrambling the pay broadcast, the broadcast channel, and the like is energization control information.

  The energization control operation in the BD recorder 100 will be described with reference to FIGS. FIG. 18 is a flowchart for explaining the operation of obtaining energization control information. FIG. 19 is a flowchart for explaining an operation of acquiring an EMM (Entitlement Management Message) based on energization control information. Here, the EMM is information including information on contract renewal of a pay channel contract for each B-CAS card. The BD recorder 100 can renew the pay broadcast contract for each B-CAS card by acquiring the EMM for each B-CAS card.

  The user can conclude a pay broadcast contract by contracting with the broadcaster (S600). Here, it is assumed that a pay broadcast contract has been concluded for the mini-shared B-CAS card inserted into the B-CAS card slot 130.

  When the pay broadcast contract is concluded, the LSI 190 acquires the energization control information via any one of the tuners 133 to 135 (S610). When the energization control information is acquired, the LSI 190 associates the acquired energization control information with the card ID of the mini-shared B-CAS card inserted in the B-CAS card slot 130 and records it in the HDD 180 (S620). .

  When it is confirmed that the energization control information is stored in the HDD 180, the LSI 170 sets a timer (not shown) so as to automatically start in a period in which energization is necessary based on the energization control information (S630). .

  When the LSI 170 is not energized (S700 in FIG. 19) and the timer indicates a period to be automatically activated (S710), the LSI 170 is automatically activated (S720). When automatically activated, the LSI 170 determines the channel setting of any one of the tuners 123 to 125 based on the energization control information stored in the HDD 180, and enters the B-CAS card slot 130 via broadcast. The EMM of the inserted mini shared B-CAS card is acquired (S730).

  When acquiring the EMM, the LSI 170 records the acquired EMM in association with the card ID of the mini-shared B-CAS card inserted in the B-CAS card slot 130 in the HDD 180 (S740).

  When the EMM is recorded in the HDD 180, the LSI 170 determines whether or not the current time has reached the maintenance period of the block for time-shift recording (provided for about 10 minutes per day) (S750). If it is determined that the maintenance period has come, the LSI 170 transmits the EMM stored in the HDD 180 to the LSI 190 and causes the LSI 190 to update the mini shared B-CAS card inserted in the B-CAS card slot 130 ( S760).

  As described above, the BD recorder 100 according to the present embodiment acquires the EMM of the shared B-CAS card in the block for time shift recording in the block for normal recording. The reason for this configuration will be described.

  In principle, the block for time-shift recording receives the broadcast of the channel selected by the user throughout the day, and continues to record the program data generated based on the received program in the HDD 180. Accordingly, in the block for time shift recording, there may be a case where the broadcast of the channel on which the EMM is broadcast cannot be received during the period indicated by the energization control information. Therefore, the BD recorder 100 according to the present embodiment acquires the EMM of the shared B-CAS card in the block for time shift recording in the block for normal recording.

  In the BD recorder 100 according to the present embodiment, the LSI 170 records the card ID of the shared B-CAS card in the block for time shift recording and the energization control information in the HDD 180 in association with each other. As a result, even if there are a plurality of shared B-CAS cards in the block for time shift recording, the LSI 170 determines that the energization control information stored in the HDD 180 is the energization control information of any shared B-CAS card. Can be determined.

  Further, in the BD recorder 100 according to the present embodiment, the LSI 170 records the card ID of the shared B-CAS card and the EMM in the block for time shift recording in the HDD 180 in association with each other. As a result, even when there are a plurality of shared B-CAS cards in the block for time shift recording, the LSI 170 determines which shared B-CAS card the EMM stored in the HDD 180 is. I can judge.

1-4-5. Warning screen display operation regarding pay broadcast contract The warning screen display operation regarding pay broadcast contract in the BD recorder 100 will be described with reference to FIGS. FIG. 20 is a flowchart for explaining a warning screen display operation related to a pay broadcast contract. FIG. 21 is a diagram illustrating a display example of a warning screen.

  In a state where the power of the BD recorder 100 is turned on (S800), the LSI 170 determines whether or not a pay broadcast contract is concluded for the mini shared B-CAS card inserted in the B-CAS card slot 130. (S810). Specifically, the LSI 170 determines whether the HDD 180 stores energization control information associated with the card ID of the mini-shared B-CAS card inserted in the B-CAS card slot 130.

  If it is determined that the pay broadcast contract is concluded, the LSI 170 determines whether the pay broadcast contract is also concluded for the shared B-CAS card inserted into the front B-CAS card slot 120 (S820). ). If it is determined that the pay broadcast contract has not been concluded, the LSI 170 controls the HDMI 220 to output the warning screen data as shown in FIG. 21 (S840). The warning screen shown in FIG. 21 shows the shared B inserted in the B-CAS card slot 120 when the mini shared B-CAS card inserted in the B-CAS card slot 130 has concluded a pay broadcast contract. -A screen that prompts the user to conclude a pay broadcast contract for the CAS card. On the other hand, if it is determined that the pay broadcast contract is concluded, the LSI 170 does not output the warning screen data to the television 300 via the HDMI 220 (S830).

  As described above, the BD recorder 100 according to the present embodiment has the B-CAS card slot 120 when the mini-shared B-CAS card inserted in the B-CAS card slot 130 has signed a pay broadcast contract. A screen prompting the user to conclude a pay broadcast contract is also output for another shared B-CAS card inserted into the card. The reason for this configuration will be described next.

  Among pay broadcast contracts, there is a pack contract that simultaneously contracts a plurality of channels (for example, 9 channels). Here, it is assumed that the user has signed a pack contract for the mini-shared B-CAS card inserted into the B-CAS card slot 130. In such a case, when the user makes a time shift recording reservation for the channel received via the tuner 133 to the tuner 135, the user can perform time shift recording for three channels. . On the other hand, it is assumed that the tuners 123 to 125 are not used. In this case, the user may want to use the tuners 123 to 125 to view a pay broadcast that has not been time-shift recorded. However, when a pay broadcast contract is not concluded for the shared B-CAS card inserted into the B-CAS card slot 120, the user uses the tuner 123 to the tuner 125 to watch the pay broadcast. It will not be possible. Such a situation may occur when there is a user who does not recognize that a pay broadcast contract must be concluded for each B-CAS card.

  Therefore, the BD recorder 100 of the present embodiment is inserted into the B-CAS card slot 120 when the mini-shared B-CAS card inserted into the B-CAS card slot 130 has signed a pay broadcast contract. The shared B-CAS card is also configured to output a screen that prompts the user to conclude a pay broadcast contract. With this configuration, the user concludes a pay broadcast contract for the shared B-CAS card inserted in the B-CAS card slot 120 in order to view the pay broadcast using the tuners 123 to 125. Recognize that there is a need and take the necessary response.

1-4-6. Reception status confirmation operation and reception status display operation of shared B-CAS card The BD recorder 100 includes a shared B-CAS card inserted into the B-CAS card slot 120 and a mini shared card inserted into the B-CAS card slot 130. Use two shared B-CAS cards with B-CAS cards. Since there are two shared B-CAS cards, the user pays for any of the shared B-CAS cards when a pay broadcast contract is concluded only for one of the shared B-CAS cards. You may be confused or have signed a broadcast contract.

  Therefore, the BD recorder 100 of the present embodiment receives broadcasts by the shared B-CAS card inserted into the B-CAS card slot 120 and the mini shared B-CAS card inserted into the B-CAS card slot 130. The situation was confirmed and the confirmed reception result was shown to the user. Hereinafter, the reception status confirmation operation and the reception status display operation of the shared B-CAS card in the BD recorder 100 will be described with reference to FIGS.

  FIG. 22 is a flowchart showing the reception status confirmation operation of the shared B-CAS card. FIG. 23 is a schematic diagram for explaining the log file of the reception status confirmation result.

  When a block for time shift recording of the BD recorder 100 is executing a time shift recording operation or the like (S900), the LSI 170 determines whether or not the current time is a maintenance period for the block for time shift recording. Judgment is made (S910). Information regarding the maintenance period is stored in the HDD 180. The LSI 170 can determine whether the maintenance period has been reached by referring to the timer and the information related to the maintenance period stored in the HDD 180. When it is determined that the maintenance period has come, the LSI 170 instructs the LSI 190 to stop time-shift recording, and the LSI 170 is inserted into the shared B-CAS card inserted into the B-CAS card slot 120 and the B-CAS card slot 130. The reception confirmation operation of each channel by the mini shared B-CAS card is sequentially executed (S920).

  Specifically, the LSI 170 uses the shared B-CAS card inserted into the B-CAS card slot 120 and the mini shared B-CAS card inserted into the B-CAS card slot 130 to use the descrambler 126. 136 determines whether the broadcast program of each channel can be descrambled. The LSI 170 determines that the descrambling process by the descrambler 126, 136 has been successful when the decoding process of the program data after the descrambling process is successful, while the decoding process of the program data after the descrambling process has failed. In this case, it is determined that the descrambling process by the descrambler 126, 136 has failed. The LSI 170 determines that the channel can be received if the descrambling process by the descrambler 126, 136 is successful, and on the other hand, if the descrambling process fails, the LSI 170 cannot receive the channel. Judge. The LSI 170 determines which channels can be received for each shared B-CAS card and which channels cannot be received.

  When the reception confirmation of all the channels is completed in each shared B-CAS card, the LSI 170 updates the log file of the reception confirmation result stored in the HDD 180 (S930). The log file of the reception confirmation result is generated when the reception confirmation of each channel is performed for the first time, and is recorded in the HDD 180. Also, the log file of the reception confirmation result is stored in the HDD 180 so that it can be identified for each shared B-CAS card which shared B-CAS card is the reception confirmation result log file. That is, in the BD recorder 100, the log file of the reception confirmation result of the shared B-CAS card inserted in the B-CAS card slot 120 and the mini shared B-CAS card inserted in the B-CAS card slot 130. The log file of the reception confirmation result is stored in the HDD 180 in association with the card ID of each shared B-CAS card.

  FIG. 23 shows an example of the structure of the log file of the reception confirmation result. As shown in the figure, the reception confirmation result log file includes the date and time when the reception confirmation operation was performed, and a code indicating the confirmation result. Here, the code indicating the reception confirmation result is composed of the same number of bits as the number of channels on which the reception confirmation is performed. Each bit of the code indicating the reception confirmation result is associated with a predetermined channel. In the present embodiment, reception confirmation is performed for 10 channels (BS broadcast and CS broadcast). Therefore, the code indicating the reception confirmation result is composed of a 10-digit bit string. Here, “1” of each bit indicates that reception was successful, and “0” indicates that reception failed. In the example of FIG. 23, the channel associated with the third digit from the left of the code indicating the reception confirmation result is received from October 17th 2012 to October 24th 2012 because reception is impossible. It has been shown that it has changed possible.

  Next, the reception status display operation of the shared B-CAS card in the BD recorder 100 will be described. FIG. 24 is a flowchart showing the reception status display operation of the shared B-CAS card. FIG. 25 is a schematic diagram for explaining a screen indicating a reception status.

  When the LSI 170 is displaying a menu screen for accepting the operation of the BD recorder 100 from the user (S1000), whether the display instruction of the reception status confirmation screen of the shared B-CAS card is accepted from the user via the menu screen Is determined (S1010).

  When it is determined that the display instruction of the reception status confirmation screen of the shared B-CAS card has been received from the user, the LSI 170, based on the reception confirmation result (log file) of the shared B-CAS card stored in the HDD 180, -The reception status confirmation screen data indicating the reception status of the CAS card is generated, and the generated screen data is output to the television 300 via the HDMI 220 (S1020). Specifically, the LSI 170 outputs data on a reception status confirmation screen as shown in FIG. 25 to the television 300 via the HDMI 220. Details of the reception status confirmation screen shown in FIG. 25 will be described later. In the present embodiment, when an instruction to display the reception status confirmation screen of the shared B-CAS card is received from the user via the menu screen, the shared B-CAS card slot 120 is first inserted. The data on the reception status confirmation screen of the B-CAS card is output. In addition, in FIG. 25, the reception status confirmation screen of the mini shared B-CAS card inserted in the B-CAS card slot 130 is shown as an example.

  When the data on the reception status confirmation screen of the shared B-CAS card inserted in the B-CAS card slot 120 is output, the LSI 170 accepts an instruction to change the shared B-CAS card for displaying the reception status confirmation screen from the user. It is determined whether or not (S1030).

  If it is determined that the change instruction has been received, the LSI 170 determines the mini-shared B-CAS card based on the reception confirmation result of the mini-shared B-CAS card inserted in the B-CAS card slot 130 stored in the HDD 180. Data of a reception status confirmation screen indicating the reception status is generated, and the generated screen data is output to the television 300 via the HDMI 220 (S1040). Specifically, the LSI 170 outputs data of a reception status confirmation screen as shown in FIG. 25 to the television 300 via the HDMI 220.

  When the screen data indicating the reception status of the mini shared B-CAS card is output, the LSI 170 determines whether or not there has been an instruction from the user to change the shared B-CAS card that displays the reception status confirmation screen (S1050). . If it is determined that there is a change instruction, the LSI 170 returns to step S1020 again, and outputs the data on the reception status confirmation screen of the shared B-CAS card inserted in the B-CAS card slot 120 to the television 300 via the HDMI 220. (S1020). Thereafter, the same processing is repeated.

  Next, the reception status confirmation screen showing the reception status of the shared B-CAS card shown in FIG. 25 will be described.

  As shown in FIG. 25, the reception status confirmation screen showing the reception status of the shared B-CAS card shows the channel number of each channel, the broadcasting station name of each channel, and whether each channel is a pay channel or a free channel. The table 500 which matched the information which shows and the information which shows the reception condition shown by "(circle)" and "x" is included. Here, “◯” means that the corresponding channel has been successfully received, and “X” means that the corresponding channel has failed to be received. Further, the table 500 includes items of “previous” and “current” as information indicating the reception status. Here, “previous” indicates the reception status when the reception confirmation screen of the shared B-CAS card was previously displayed. “This time” indicates the current reception status of the shared B-CAS card.

  In addition, this screen includes an icon 510 indicating which of the shared B-CAS cards is currently being received. In the icon 510, it can be specified which shared B-CAS card currently displaying the reception status is a B-CAS card inserted into which B-CAS card slot among a plurality of B-CAS card slots. It is like that. Specifically, hatched hatching 520 is attached to the B-CAS card slot in which the shared B-CAS card displaying the current reception status is inserted.

  As described above, the BD recorder 100 according to the present embodiment automatically controls the descrambler 126 so as to perform the descrambling process sequentially on the program data of different channels, and descrambles the program data of any channel. Information indicating whether the processing was successful was recorded in the HDD 180. Thereby, the BD recorder 100 can present to the user information regarding which channel can be received by each shared B-CAS card and which channel cannot be received.

  Further, the BD recorder 100 according to the present embodiment outputs a screen indicating the reception status of each channel regarding the shared B-CAS card. Thereby, the BD recorder 100 can make the user recognize which channel can be received by the shared B-CAS card and which channel cannot be received.

  In addition, the BD recorder 100 according to the present embodiment displays the previous reception status and the current reception status together on the reception status confirmation screen. Thereby, the user can grasp the change in the reception status of each channel using the shared B-CAS card by comparing the previous reception result with the current reception result.

  Also, the BD recorder 100 according to the present embodiment specifies which B-CAS card slot is the B-CAS card slot in which the reception status confirmation screen currently displayed on the reception status confirmation screen is displayed. It was decided to display information. As a result, the BD recorder 100 can make the user easily understand which shared B-CAS card the currently displayed reception status relates to.

1-4-7. Broadcast Mail Reception Operation, Broadcast Mail List Display Operation The broadcast mail reception operation and broadcast mail list display operation in the BD recorder 100 will be described with reference to FIGS. FIG. 26 is a flowchart showing a broadcast mail receiving operation. FIG. 27 is a flowchart showing the broadcast mail list display operation. FIG. 28 is a schematic diagram for explaining a broadcast mail list display screen.

  First, a broadcast mail reception operation will be described with reference to FIG. In the standby state (S1100), the LSI 170 determines whether a broadcast mail has been received via the tuners 123 to 155 (S1110). If it is determined that the broadcast mail has been received, the LSI 170 determines which B-CAS card is one of the B-CAS cards in which the received broadcast mail is inserted into the B-CAS card slot 120 to the B-CAS card slot 150. It is determined whether the broadcast mail is transmitted (S1120). Specifically, the LSI 170 makes a determination by referring to information regarding the card ID of the B-CAS card included in the broadcast mail. After the determination, the LSI 170 associates the broadcast mail with the card ID information of the B-CAS card and records them in the HDD 180 (S1130).

  Next, the broadcast mail list display operation will be described with reference to FIG. The LSI 170 determines whether a broadcast mail list display instruction has been received (S1210) while displaying a menu screen that receives instructions from the user (S1200). If it is determined that a broadcast mail list display instruction has been received, LSI 170 reads broadcast mail information stored in HDD 180, generates broadcast mail list display screen data, and generates broadcast mail list display screen data. Are output to the television 300 via the HDMI 220 (S1220). FIG. 28 shows an example of a broadcast mail list display screen. Details of the broadcast mail list display screen will be described later.

  When the broadcast mail list display screen is output, the LSI 170 waits until any broadcast mail is selected by the user on the list display screen (S1230). Specifically, the user moves the cursor displayed in FIG. 28 with the remote controller 400 or the like and selects a broadcast mail. When any broadcast mail is selected, the LSI 170 reads data indicating the content of the selected broadcast mail from the HDD 180 and outputs the data to the television 300 via the HDMI 220 (S1240).

  The broadcast mail list screen shown in FIG. 28 will be described. On the broadcast mail list screen, information indicating the reception date, title, and position of the B-CAS card slot in which the B-CAS card is inserted is associated with each broadcast mail.

  In the item of the position of the B-CAS card slot in which the B-CAS card is inserted, either the number 350 to the number 400 indicated by the icon 350 or the icon 360, or the “?” Mark is assigned. Here, the number 370 indicates the B-CAS card slot 120, the number 380 indicates the B-CAS card slot 130, the number 390 indicates the B-CAS card slot 140, and the number 400 indicates the B-CAS card. A slot 150 is shown. The “?” Mark indicates that a B-CAS card having a card ID that matches the card ID of the B-CAS card indicated as the broadcast mail transmission destination is inserted in any of the card slots 120 to 150. Indicates no case.

  As described above, in the BD recorder 100 according to the present embodiment, the broadcast mail received via the tuners 123 to 155 is broadcast to any B-CAS card among the plurality of B-CAS cards. It is determined whether it is a mail, and the broadcast mail and the card ID of the B-CAS card are associated with each other and recorded in the HDD 180 based on the determination result. Thereby, the BD recorder 100 can present to the user information indicating to which B-CAS card each broadcast mail has been transmitted.

  Further, the BD recorder 100 according to the present embodiment includes broadcast mail stored in the HDD 180 and information indicating which B-CAS card the broadcast mail is transmitted to. It is configured to output a list display screen of associated broadcast mails. Thereby, the BD recorder 100 can make a user recognize to which B-CAS card each broadcast mail was transmitted.

  In addition, the BD recorder 100 according to the present embodiment applies to a B-CAS card in which broadcast mail is inserted into any B-CAS card slot among the B-CAS card slot 120 to the B-CAS card slot 150. If the target B-CAS card is not transmitted, a display indicating that the target B-CAS card is not inserted into any B-CAS card slot (“?” Mark in the present embodiment) is displayed. Thereby, the BD recorder 100 can make a user recognize which broadcast mail does not have the target B-CAS card.

1-4-8. Operation when the shared B-CAS card is replaced In the BD recorder 100, the mini shared B-CAS card inserted into the B-CAS card slot 130 into which the time-shift recording B-CAS card is inserted is different The operation when the mini-shared B-CAS card is replaced will be described with reference to FIGS. 29 and 30. FIG. FIG. 29 is a flowchart showing an operation when the mini shared B-CAS card is replaced. FIG. 30 is a schematic diagram showing a warning screen.

  In the standby state (S1300), the LSI 170 determines whether or not the mini shared B-CAS card inserted into the B-CAS card slot 130 via the LSI 190 has been replaced with another mini shared B-CAS card ( S1310). Specifically, this determination is performed as follows. The card ID of the mini-shared B-CAS card inserted in the B-CAS card slot 130 is stored in the HDD 180. For example, the card ID of a mini shared B-CAS card inserted in the B-CAS card slot 130 is stored in the HDD 180 at the time of initial setting. When accessing the mini shared B-CAS card, the LSI 170 compares the card ID stored in the HDD 180 with the card ID of the mini shared B-CAS card currently inserted in the B-CAS card slot 130. . The LSI 170 determines that the mini shared B-CAS card has been replaced when both card IDs are different.

  If it is determined that the mini-shared B-CAS card has been replaced, the LSI 170 outputs warning screen data as shown in FIG. 30 to the television 300 via the HDMI 220 (S1320). Here, the warning screen shown in FIG. 30 is a screen that informs the user that there is a risk that viewing and recording of the pay program may not be performed normally.

  If it is determined that the mini shared B-CAS card inserted in the B-CAS card slot 130 has been replaced while the power of the BD recorder 100 is turned off, the LSI 170 is turned on the next time the power is turned on. The warning screen data as shown in FIG. 30 is output to the television 300 via the HDMI 220. In addition, when the user presses the enter button on the remote controller 400 while the warning screen shown in FIG. 30 is being output, the LSI 170 will share a new mini that is currently inserted in the B-CAS card slot 130. The card ID of the B-CAS card is stored in the HDD 180. Thereby, the BD recorder 100 does not display the warning screen until it detects further replacement of the B-CAS card.

  As described above, the BD recorder 100 according to the present embodiment outputs a warning screen when the shared B-CAS card for time shift recording is replaced with another shared B-CAS card. As a result, the BD recorder 100 can view or record a pay program when the mini shared B-CAS card for time shift recording newly inserted into the B-CAS card slot 130 does not have a pay broadcast contract. It is possible to notify the user that there is a risk of being unable to do so.

1-4-9. NHK (Japanese Broadcasting Corporation) Automatic Display Message Display Operation The NHK (Japanese Broadcasting Corporation) automatic display message display operation in the BD recorder 100 according to this embodiment will be described with reference to FIGS. FIG. 31 is a flowchart showing the display operation of the NHK automatic display message. FIG. 32 is a schematic diagram for explaining an NHK automatic display message.

  First, the NHK automatic display message will be described. The NHK automatic display message is a message 501 as shown in FIG. The automatic display message indicates a content that prompts the user to conclude a broadcast reception contract with NHK. When the BS / CS antenna receives the NHK BS broadcast, an automatic display message may be displayed.

  First, the display operation of the automatic display message relating to the viewing block will be described. The BS / CS antenna receives the NHKBS broadcast program and the automatic display message, and transmits the received data to the tuners 123 to 125. The tuners 123 to 125 generate program data before descrambling processing and an automatic display message based on the received data, and transmit the generated data to the descrambler 126. The descrambler 126 executes descrambling of program data before descrambling using the shared B-CAS card inserted in the B-CAS card slot 120. Further, the LSI 170 makes an inquiry to the shared B-CAS card inserted into the B-CAS card slot 120 to determine whether or not to superimpose an automatic display message on the program data after descrambling. Then, the LSI 170 superimposes the program data on which the automatic display message is superimposed or the automatic display message on the basis of the descrambled program data generated by the descrambler 126 and the response result from the shared B-CAS card. Program data that has not been generated is generated. Hereinafter, this operation will be described in more detail.

  The LSI 170 receives a signal indicating whether or not the automatic display message should be superimposed from the shared B-CAS card inserted in the B-CAS card slot 120. Specifically, when the user does nothing, the shared B-CAS card inserted in the B-CAS card slot 120 sends a signal indicating that an automatic display message should be superimposed to the LSI 170. Send. On the other hand, the user communicates the card ID of the shared B-CAS card inserted into the B-CAS card slot 120 by telephone or the like to NHK, and as a result, the B- When the shared B-CAS card inserted in the CAS card slot 120 receives the EMM, the shared B-CAS card transmits a signal indicating that the automatic display message should not be superimposed to the LSI 170. To do.

  By the way, the NHKBS reception contract may be concluded for each household (household), and is not necessarily concluded for each B-CAS card. However, if the user informs NHK only of the card ID of the shared B-CAS card inserted in the B-CAS card slot 120, the shared B-CAS inserted in the B-CAS card slot 120 is assumed. The EMM is transmitted to the card via the BS / CS antenna, but the EMM is not transmitted to the mini shared B-CAS card inserted in the B-CAS card slot 130. As a result, for example, when a household has an NHKBS reception contract but outputs a video to the television 300 using a mini-shared B-CAS card inserted in the B-CAS card slot 130. , An automatic display message will be displayed. In this case, the user may be confused because it is displayed that the contract is not concluded although the NHKBS contract is concluded.

  In order to eliminate such a state, the BD recorder 100 controls the display operation of the automatic display message as shown in FIG.

  When the user gives an instruction to view NHKBS (S1400), the LSI 170 uses a shared B-CAS card (viewing B-CAS card) in which the viewing instruction is inserted into the B-CAS card slot 120. Or a mini shared B-CAS card (time-shift recording B-CAS card) inserted in the B-CAS card slot 130 is used (S1410).

  If it is determined that the viewing B-CAS card is used, the LSI 170 automatically selects information based on information obtained from the viewing B-CAS card (information indicating whether or not an automatic display message should be superimposed). It is determined whether or not the display message is superimposed on the program data (S1420). If the information obtained from the viewing B-CAS card is information indicating that the automatic display message should be superimposed, the LSI 170 outputs data in which the automatic display message is superimposed on the program data (S1430). On the other hand, if the information obtained from the B-CAS card for viewing is information indicating that the automatic display message should not be superimposed, the LSI 170 displays the program data without superimposing the automatic display message on the program data. It outputs (S1440).

  On the other hand, if it is determined in step S1410 that the time-shift B-CAS card is used, the LSI 170 automatically displays the program data regardless of the content of the information obtained from the time-shift B-CAS card. Program data is output without superimposing a message (S1450).

  As described above, in the present embodiment, the BD recorder 100 uses the shared B-CAS card inserted into the B-CAS card slot 120 for program data after descrambling for viewing B -An automatic display message is superimposed on the program data according to the information obtained from the CAS card and output. On the other hand, the automatic display message is not superimposed on the program data after descrambling using the mini-shared B-CAS card inserted in the B-CAS card slot 130, and the automatic display message is not superimposed. Output program data. With such control, the BD recorder 100 reduces the possibility that the user will output an automatic display message even though the user has already notified the NHK of the card ID of the B-CAS card for viewing. it can.

  The automatic display message display operation described above is not limited to broadcasting by NHK, but is effective for broadcasting from a broadcasting station that only needs to conclude a reception contract on a household (household) basis.

1-4-10. Display Operation of Recording Schedule Status List Screen The recording reservation status list screen display operation in the BD recorder 100 will be described with reference to FIGS. 33 and 34. FIG. FIG. 33 is a flowchart showing the display operation of the recording reservation status list screen. FIG. 34 is a schematic diagram for explaining a recording reservation status list screen.

When an instruction to display a recording reservation status list screen is received from the user via the menu screen (S1500), the LSI 170 refers to the recording reservation status list information stored in the HDD 160 and records as shown in FIG. The reservation status list screen data is generated and output to the television 300 via the HDMI 220 (1510). At this stage, items other than the items of the antenna reception level and viewing confirmation are output from the information shown in FIG. Here, the recording state shown in FIG. 34 indicates the recording state of each channel, and includes the following four states.

  When the recording reservation status list screen data is output, the LSI 170 confirms the antenna reception level of the time shift channel 1 (channel received by the tuner 133) (1520). When the confirmation of the antenna reception level is completed, the LSI 170 outputs information (numerical value) indicating the antenna reception level for which the confirmation has been completed so as to be superimposed on the recording reservation status list screen currently output to the television 300 (S1530). ).

When the information indicating the antenna reception level is output, the LSI 170 performs viewing confirmation of the channel set as the time shift channel 1 (S1540). Here, viewing confirmation refers to confirmation of whether or not the received broadcast program can be viewed. For example, when a broadcast program can be received via an antenna and the descrambling process for the broadcast program is successful, it can be said that the viewing is successful. On the other hand, the broadcast program can be received via the antenna, but since the pay program is not contracted, the descrambling process for the broadcast program has failed, or the viewing confirmation has failed when the B-CAS card cannot be recognized. I can say that. In the present embodiment, the following information is displayed as a result of viewing confirmation.

  When the viewing confirmation is completed, the LSI 170 outputs information indicating the result of the viewing confirmation for which the confirmation has been completed so as to be superimposed on the recording reservation status list screen currently output to the television 300 (S1550).

  When the information indicating the viewing confirmation result is output, the LSI 170 repeats the processing in steps S1520 to S1550 until the antenna reception level and the viewing confirmation result are output on all channels (time shift channels 1 to 9). (S1560). Time shift channels 1 to 9 correspond to recording reservation channels assigned to the tuners 133 to 155.

  When the output of the antenna reception level and the output of the viewing confirmation result for all channels is completed, the display operation of the recording reservation status list screen is completed (S1570).

  As described above, the BD recorder 100 according to the present embodiment associates, for each B-CAS card, information indicating a channel set for recording reservation and information regarding availability of viewing / listening of the channel set for recording reservation. Output the screen. Thereby, the BD recorder 100 can notify the user of the status of whether or not each program currently set for recording reservation can be viewed.

  In addition, the BD recorder 100 according to the present embodiment includes, for each of a plurality of B-CAS cards, information indicating channels set for recording reservation, information regarding availability of viewing / listening of channels set for recording reservation, A screen in which information on reception sensitivity is associated is output. Thereby, when viewing confirmation fails, the BD recorder 100 can inform the user whether the cause is that the broadcast program cannot be descrambled or the reception sensitivity of the antenna.

1-4-11. Display Operation of Pay Broadcast Contract Information Screen During Normal Viewing The operation of displaying the pay broadcast contract information screen during normal viewing in the BD recorder 100 will be described with reference to FIGS. FIG. 35 is a flowchart showing the operation of the BD recorder 100 when an instruction to display a pay broadcast contract guidance screen is received from the user during normal program viewing. FIG. 36 is a schematic diagram showing a display example of the CA alternative menu in the BD recorder 100. FIG. 37 is a schematic diagram showing a display example of a B-CAS card selection screen in the BD recorder 100. FIG. 38 is a schematic diagram showing a display example of a pay broadcast contract guidance screen in the BD recorder 100.

  In the case of normal viewing of program data, descrambling processing is performed on program data received by any one of tuners 123 to 125 using a shared B-CAS card inserted into the B-CAS card slot 120. Is implemented. The program data after the descrambling process is output to the television 300 via the HDMI 220, and the video of the program is displayed on the television 300. When an instruction for performing such normal viewing is received from the user (S1800), the LSI 170 uses the shared B-CAS card inserted in the B-CAS card slot 120 to de-code the target channel. A scramble process is performed, and it is determined whether or not the descrambling process is successful (that is, whether or not the target channel can be viewed) (S1810).

  When it is determined that the descrambling process has failed (that is, when viewing is not possible), the LSI 170 displays a screen (hereinafter referred to as “CA”) as shown in FIG. 36 based on the information received via any one of the tuners 123 to 125. The data of “substitute menu screen” is generated and output to the television 300 via the HDMI 220 (S1840). The CA alternative menu screen is a screen for inquiring the user whether or not to switch to a guide channel for a pay broadcast contract. If a user tries to view a program but cannot view the program because he / she has not yet contracted, he / she may consider signing a contract to enable viewing. Therefore, by displaying such a screen for inquiries, the convenience of the user for concluding a contract for pay broadcasting is intended.

  When the CA alternative menu screen data is output, the LSI 170 waits for an instruction from the user to shift to the pay channel subscription channel (S1850). When receiving the instruction to shift to the guide channel, the LSI 170 records information on the channel number of the guide channel received via any one of the tuners 123 to 125 in an internal memory (not shown). Then, the LSI 170 outputs data of the selection screen to the television 300 via the HDMI 220 in order to display the selection screen of the shared B-CAS card as shown in FIG. S1860). On this selection screen, the user can use a normal broadcast / recording card (a shared B-CAS card inserted into the front card slot 120) and a time-shift recording card as a pay broadcast contracted card. Any of (a shared B-CAS card inserted into the card slot 130 on the back) can be selected. Details of the shared B-CAS card selection screen will be described later.

  When the data of the selection screen of the shared B-CAS card is output, the LSI 170 waits for an instruction to select the shared B-CAS card from the user (S1870). When the selection of the shared B-CAS card is received from the user, the LSI 170 uses the shared B-CAS card selected by the user for the image data of the pay channel guide channel screen as shown in FIG. The descrambling process is performed and output to the television 300 via the HDMI 220 (S1890). In step S1870, the card ID of the shared B-CAS card displayed on the guide channel screen is the shared B-CAS card selected by the user (the card inserted into the B-CAS card slot 120 or 130). Card ID. When the user selects the shared B-CAS card for time shift recording, if the shared B-CAS card for time shift recording is executing time shift recording, the time shift recording is temporarily performed. You may stop.

  The user notifies the card ID of the shared B-CAS card over the telephone to the operator of the broadcaster who provides the pay broadcast while viewing the screen of the guide channel as shown in FIG. 38 displayed on the TV 300. Can do. As a result, the user can conclude a pay broadcast contract for the shared B-CAS card that conveys the card ID.

  As described above, the BD recorder 100 according to the present embodiment uses the shared B-CAS card before the screen data for guiding the user to conclude the pay broadcast contract is output to the television 300 via the HDMI 220. The screen to be selected is output to the television 300 via the HDMI 220. The reason for this configuration will be described next.

  If the BD recorder 100 does not output a screen for allowing the user to select a shared B-CAS card before outputting a screen for guiding the user to conclude a pay broadcast contract, the following inconvenience may occur. is there. The BD recorder 100 has a card ID of a shared B-CAS card (normal recording or viewing B-CAS card) inserted in the B-CAS card slot 120 on the screen for guiding the user to conclude a pay broadcast contract. Will be displayed. Suppose that a user wishes to conclude a pay broadcast contract for a shared B-CAS card for time shift recording. In this case, if the card ID of the B-CAS card for normal recording or viewing is displayed on the television 300, the user mistakenly sets the card ID of the B-CAS card for normal recording or viewing, and the broadcaster There is a risk of notifying the operator. This is because, in general, a common B-CAS card for normal recording or viewing and a shared B-CAS card for time-shift recording are separate shared B-CAS cards, and each shared B-CAS is related to a pay broadcast contract. This is because it is considered that there are not a few users who do not recognize that it is necessary to conclude a CAS card. If a contract is made with a shared B-CAS card inserted into the B-CAS card slot 120, there is a disadvantage that time-shift recording cannot be performed for the contracted pay broadcast.

  Therefore, the BD recorder 100 according to the present embodiment allows the user to select a shared B-CAS card before outputting a screen for guiding the user to conclude a pay broadcast contract to the television 300 via the HDMI 220. The screen is output to the television 300 via the HDMI 220. Thus, before outputting the card ID of the shared B-CAS card on the pay broadcast contract guide screen, the user can be inquired about the shared B-CAS card with which the pay broadcast contract is to be concluded. As a result, the user can more reliably select a shared B-CAS card that he / she wishes to conclude a pay broadcast contract.

  Next, details of the selection screen for the shared B-CAS card shown in FIG. 37 will be described. The selection screen for the shared B-CAS card includes an icon indicating the shared B-CAS card to be selected, a card ID of the selected shared B-CAS card, information on a contracted pay broadcast, time shift recording Contains information about the channel you are on. It should be noted that the information about the pay broadcast contracted by the selected shared B-CAS card may be acquired by referring to the latest data of the log file shown in FIG. 23, or the selected shared B-CAS card. The energization control command may be notified to the CAS card, and the response data may be obtained by referring to information that can identify the broadcaster such as ca_broadcaster_group_ID.

  Note that the BD recorder 100 according to the present embodiment interrupts the selection screen for the shared B-CAS card after outputting the CA alternative menu screen. However, it is not necessarily limited to such a configuration. For example, the shared B-CAS can be used even when a user directly designates a pay broadcast contract guide channel without outputting a screen including a link to the pay broadcast contract guide channel such as a CA alternative menu. The card selection screen may be interrupted. However, in this case, the BD recorder 100 needs to store in advance the channel number of the guide channel of the pay broadcast contract. Then, the BD recorder 100 outputs a shared B-CAS card selection screen when receiving an instruction to display the channel number of the guide channel stored in advance from the user. Therefore, when the channel number of the guide channel of the pay broadcast contract is changed later, the selection screen for the shared B-CAS card is not interrupted in an appropriate scene.

  The interruption of the selection screen of the shared B-CAS card may be generated when the LSI 170 inquires of the shared B-CAS card about the card ID, or the card ID of the shared B-CAS card is displayed in data broadcasting. It may be generated when requested to do so.

  In addition, in step S1810, the BD recorder 100 according to the present embodiment waits until receiving an instruction for normal viewing from the user. However, it is not necessarily limited to this configuration. For example, when a specific button on the remote control 400 is pressed and the link destination assigned to the button is different from the link destination (paid broadcast contract guide channel) assigned in the CA alternative menu, On the other hand, if it is the same, the screen for selecting the shared B-CAS card may be interrupted, and then the pay channel may be changed to the guide channel of the pay broadcast contract.

2. Embodiment 2
A second embodiment in which the present invention is applied to a BD recorder will be described below with reference to the drawings. Here, only the points different from the first embodiment will be described, and the points not particularly mentioned are assumed to be the same as those of the first embodiment.

2-1. External Configuration and Electrical Configuration Unlike the first embodiment, the BD recorder 100 according to the present embodiment has the same size of the plurality of shared B-CAS cards to be inserted. With reference to this point, the external configuration and electrical configuration of the BD recorder 100 of the present embodiment will be described with reference to FIGS. 39 and 40. FIG. FIG. 39 is a schematic external view showing the front and back surfaces of the BD recorder 100 of the present embodiment. FIG. 40 is a block diagram showing an electrical configuration of the BD recorder 100 of the present embodiment.

  As shown in FIGS. 39 and 40, the BD recorder 100 of the present embodiment has a B-CAS card slot 420, a B-CAS card slot 430, and a B-CAS on the front side in addition to the B-CAS card slot 120. A card slot 440 is included. The B-CAS card corresponding to each of the B-CAS card slot 420, the B-CAS card slot 430, and the B-CAS card slot 440 will be described.

  The B-CAS card slot 420 corresponds to a shared B-CAS card (red) which is a B-CAS card compatible with BS, CS, and terrestrial digital broadcasting. This shared B-CAS card is not a mini shared B-CAS card but a full size shared B-CAS card. The B-CAS card slot 430 and the B-CAS card slot 440 correspond to a terrestrial digital B-CAS card (blue) which is a B-CAS card that supports only terrestrial digital broadcasting. This terrestrial digital B-CAS card is not a mini terrestrial B-CAS card, but a full-size terrestrial B-CAS card.

  In the present embodiment, the shared B-CAS card inserted into the B-CAS card slot 120 and the shared B-CAS card inserted into the B-CAS card slot 420 have the same size. Accordingly, when the user has concluded a pay broadcast contract only for any of the shared B-CAS cards, there is a risk of confusion regarding which of the shared B-CAS cards the pay broadcast contract has been concluded. is there. Thus, in the present embodiment, a device for eliminating such fear is taken.

2-2. Initial setting operation (default setting operation)
An initial setting operation in the BD recorder 100 will be described with reference to FIGS. 41 and 42. FIG. 41 and 42 are schematic views showing display screens during the initial setting operation (purchase setting operation).

  In the present embodiment, the screen shown in FIG. 41 is displayed at the timing of displaying the screen of FIG. 5 in the first embodiment. Also, the screen shown in FIG. 42 is displayed at the timing of displaying the screen of FIG. 7 in the first embodiment. Note that a product including the BD recorder 100 according to the present embodiment includes a seal for distinguishing each of a plurality of B-CAS cards included in the BD recorder 100.

  The screen shown in FIG. 41 is a screen for prompting the user to put a sticker for distinguishing each B-CAS card on the shared B-CAS card inserted into the B-CAS card slot 120. . The screen shown in FIG. 41 further prompts the user to insert the shared B-CAS card with a sticker into the B-CAS card slot 120.

  The screen shown in FIG. 42 distinguishes each B-CAS card from the shared B-CAS card inserted into the B-CAS card slot 420 to the B-CAS card slot 440 and the terrestrial digital B-CAS card. It is a screen for prompting the user to put a sticker for the purpose. The screen shown in FIG. 42 further prompts the user to insert the shared B-CAS card with a sticker and the terrestrial digital B-CAS card into the B-CAS card slot 420 to the B-CAS card slot 440. Urging.

  Thus, the BD recorder 100 displays a screen that prompts the user to stick each sticker to each B-CAS card during the initial setting operation. Thereby, the BD recorder 100 is made to correspond to the user so that each B-CAS card can be easily distinguished even when a plurality of B-CAS cards having the same size and the same color exist.

3. Embodiment 3
The BD recorder 100 according to the present embodiment differs from the first and second embodiments in terms of energization control operations (explained in item 1-4-4 in the first embodiment). Here, an energization control operation in the BD recorder 100 according to the present embodiment will be described.

3-1. Energization Control Operation The energization control operation of the BD recorder 100 according to the present embodiment will be described with reference to FIG. The energization control information acquisition operation may be the same as in the first embodiment. FIG. 43 is a flowchart for explaining an operation of acquiring an EMM based on the energization control information.

  When the LSI 170 is not energized (S1600) and the timer indicates a period to be automatically activated (S1610), the LSI 170 is automatically activated to obtain an EMM (S1620). Specifically, when the LSI 170 is automatically activated, the channel setting of any one of the tuners 123 to 125 is determined based on the energization control information stored in the HDD 180, and B is transmitted via broadcasting. Obtain the EMM of the mini shared B-CAS card inserted in the CAS card slot 130 (S1630).

  The LSI 170 associates the acquired EMM with the card ID of the mini-shared B-CAS card inserted in the B-CAS card slot 130 and records it in the HDD 180 (S1640).

  When the acquired EMM is recorded in the HDD 180, the LSI 170 receives information including a key for descrambling the ECM (Entertainment Control Message: scrambled broadcast program) currently received by the descrambler 136 via the BS / CS antenna. ) Is being processed (S1650).

  If it is determined that the descrambler 136 is currently processing an ECM, the LSI 170 waits while the ECM is being processed. On the other hand, if it is determined that the descrambler 136 is not currently processing the ECM, the LSI 170 determines whether the descrambler 136 is currently processing the EMM received via the BS / CS antenna ( S1660).

  If it is determined that the descrambler 136 is currently processing an EMM, the LSI 170 waits. On the other hand, if it is determined that the descrambler 136 is not currently processing an EMM, the LSI 170 determines whether or not a predetermined time (30 seconds in this example) has elapsed since the EMM recorded in the HDD 180 has been acquired. (S1670).

  If it is determined that the predetermined time (30 seconds) or more has elapsed, the LSI 170 discards the EMM recorded in the HDD 180, returns to step S1630, and tries to acquire the EMM again (S1630).

  On the other hand, if it is determined that the predetermined time (30 seconds) has not passed, the LSI 170 transmits the EMM recorded in the HDD 180 to the LSI 190, and the mini shared B-CAS card inserted in the B-CAS card slot 130 into the LSI 190. Update processing is performed (S1680).

  As described above, the BD recorder 100 according to the present embodiment acquires the EMM of the shared B-CAS card in the block for time shift recording in the block for normal recording. The reason for this configuration will be described.

  In principle, the block for time-shift recording receives the broadcast of the channel selected by the user throughout the day, and continues to record the program data generated based on the received program in the HDD 180. Accordingly, in the block for time shift recording, there may be a case where the broadcast of the channel on which the EMM is broadcast cannot be received during the period indicated by the energization control information. Therefore, the BD recorder 100 according to the present embodiment acquires the EMM of the shared B-CAS card in the block for time shift recording in the block for normal recording.

4). Other Embodiments As described above, the first to third embodiments have been described as examples of the technology disclosed in the present application. However, the technology in the present disclosure is not limited to this, and can also be applied to an embodiment in which changes, replacements, additions, omissions, and the like are appropriately performed. Moreover, it is also possible to combine each component demonstrated in the said Embodiment 1-3 and it can also be set as new embodiment. Therefore, other embodiments will be exemplified below.

4-1
In the first embodiment, only the B-CAS card inserted into the B-CAS card slot 120 and the B-CAS card inserted into the B-CAS card slot 130 are used as a common B-CAS card. However, it is not necessarily limited to such an example. For example, all B-CAS cards inserted into the B-CAS card slots 120 to 150 may be shared B-CAS cards. In this case, a screen as shown in FIG. 44 may be displayed as a channel setting screen for time shift recording.

4-2
FIG. 44 is a schematic diagram for explaining a channel setting screen for time-shift recording in another embodiment. In the time-shift channel setting screen shown in FIG. 44, each B-CAS card for time-shift recording is associated with information indicating channels reserved for recording with respect to those B-CAS cards. Yes. The user can understand at a glance which channel is reserved for recording for which B-CAS card by referring to the channel setting screen for time shift.

4-3
In the first embodiment, a B-CAS card slot of a full-size shared B-CAS card is provided on the front surface of the BD recorder 100, and a mini shared B-CAS having a size smaller than the full size is provided on the back surface of the BD recorder 100. A B-CAS card slot for a card and a B-CAS card dedicated to mini terrestrial digital broadcasting is provided. However, it is not necessarily limited to such an example. For example, a B-CAS card slot of a mini shared B-CAS card is provided on the front surface of the BD recorder 100, and a B-CAS card slot of a full size shared B-CAS card is provided on the back surface of the BD recorder 100. A B-CAS card slot for inserting a digital B-CAS card or a mini terrestrial B-CAS card may be provided.

4-4
Further, in the first embodiment, in the initial setting operation, the front shared B-CAS card is inserted, and further, the rear mini shared B-CAS card and the mini terrestrial digital B-CAS card are completely inserted. For the first time, the state confirmation screen of each B-CAS card as shown in FIGS. 8 and 9 is displayed. However, it is not necessarily limited to such a configuration. For example, a screen as shown in FIG. 5 is displayed, and when the shared B-CAS card is inserted by the user, a confirmation screen as shown in FIG. 8 is displayed, and a screen as shown in FIG. 7 is displayed. When the mini shared B-CAS card and the terrestrial digital B-CAS card are inserted from the user, a confirmation screen as shown in FIG. 9 may be displayed. Thereby, the user can confirm the state of the inserted B-CAS card each time the B-CAS card is inserted.

4-5
In the first embodiment, the free viewing period is automatically started only for the mini shared B-CAS card inserted in the B-CAS card slot 130. However, it is not necessarily limited to such an example. For example, the free viewing period is automatically started for both the shared B-CAS card inserted into the B-CAS card slot 120 and the shared B-CAS card inserted into the B-CAS card slot 130. May be.

4-6
In the first embodiment, the free viewing period is automatically started for the mini-shared B-CAS card inserted in the B-CAS card slot 130 during the initial setting operation (purchase setting). However, it is not necessarily limited to such an example. For example, the free viewing period may be automatically started for the mini shared B-CAS card inserted into the B-CAS card slot 130 periodically, such as during the system maintenance period of the BD recorder 100 (automatically mini). The descrambling process of the pay channel using the shared B-CAS card may be executed).

  The advantages of such a configuration will be described. For example, when the antenna wire is disconnected at the initial setting, or when a free broadcast is broadcast on a specific pay channel at the initial setting, the mini shared B-CAS card inserted into the B-CAS card slot 130 is used. The free viewing period does not start even if you try to apply descrambling using. In this case, the problem that the free viewing period of the pay broadcast is substantially extended cannot be solved. However, if the free viewing period is automatically started for the mini-shared B-CAS card inserted into the B-CAS card slot 130 periodically, such as during the system maintenance period of the BD recorder 100, the free viewing period is initially set. Even for paid channels where will not start, the free viewing period will start as early as possible.

4-7
In the first embodiment, the BD recorder 100 uses one of the tuners 123 to 125 to receive the broadcast for the reception confirmation screen. Further, the LSI 170 of the BD recorder 100 inserts the received program data into a B-CAS card (any one of the B-CAS card slot 120 to the B-CAS card slot 150 to be received). The descrambling process was executed using a B-CAS card. Further, the BD recorder 100 outputs the image after descrambling processing to the reception confirmation screen. However, it is not necessarily limited to such an example. For example, broadcast reception for the reception confirmation screen may be performed using the tuner 133 to the tuner 155. That is, the broadcast for the reception confirmation screen may be received using a tuner associated with the B-CAS card for which reception confirmation is to be performed. Further, the LSI 190 to the LSI 210 may be used for processing the received program data. That is, the descrambling process for the reception confirmation screen may be performed using an LSI associated with the B-CAS card for which reception confirmation is desired.

4-8
Further, in the first embodiment, the BD recorder 100 uses the LSI 190 at the time of concluding a pay broadcast contract for the mini shared B-CAS card inserted in the B-CAS card slot 130, and uses the mini shared B-CAS card. The energization control information was obtained. However, it is not necessarily limited to such an example. For example, when the block for normal recording or viewing is paused (when the power is turned off, during a maintenance period, etc.), the mini-B-CAS card inserted into the B-CAS card slot 130 is energized using the LSI 170. Control information may be acquired. According to such a configuration, it is possible to acquire not only the energization control information broadcasted when a contract for pay broadcasting is concluded but also the energization control information broadcast immediately before the energization period.

4-9
Further, in the first embodiment, the BD recorder 100 is inserted into the B-CAS card slot 120 when the mini-shared B-CAS card inserted into the B-CAS card slot 130 has concluded a pay broadcast contract. When the shared B-CAS card is not signed with a pay broadcast contract, a warning screen is output (see FIG. 20). However, it is not necessarily limited to such an example. For example, even if the LSI 170 periodically detects whether there is a change in the pay broadcast contract status of each B-CAS card, and the contract status changes, the image data of the message screen is output. Good. For example, image data of a message screen as shown in FIG. 44B may be output. Alternatively, when it is detected that a certain B-CAS card has entered into a new paid broadcasting contract, a screen including a message such as “A paid channel contract has been detected.” Is output. When the pay broadcast cannot be descrambled by the CAS card, a screen including a message such as “XX pay channel cannot be viewed” may be output. In this way, by notifying the user that the contract state of the B-CAS card has changed, the user can easily know that the contract state of the B-CAS card has changed.

4-10
In the first embodiment, the BD recorder 100 displays the reception confirmation screen on the reservation setting screen for time shift recording. However, it is not necessarily limited to such an example. For example, information (for example, “◯”, “×”, “OK”, “NG”, etc.) indicating the confirmation result of the viewing confirmation may be displayed without displaying the reception confirmation screen.

4-11
In the first embodiment, the period for notifying the mini-shared B-CAS card inserted in the B-CAS card slot 130 of the EMM is the maintenance period for the block for time shift recording. However, it is not necessarily limited to such an example. For example, immediately after the LSI 170 acquires the EMM, the acquired EMM may be notified to the mini shared B-CAS card inserted in the B-CAS card slot 130.

4-12
In the first embodiment, the mini-shared B-CAS card inserted into the B-CAS card slot 130 has a pay broadcast contract and is inserted into the B-CAS card slot 120. When the LSI 170 detects that the shared B-CAS card does not conclude a pay broadcast contract, the warning screen data is output via the HDMI 220. However, it is not necessarily limited to such an example. For example, when it is detected that a B-CAS card is inserted into the B-CAS card slot, when the card ID of the B-CAS card inserted into the B-CAS card slot is changed, The warning screen data may be output via the HDMI 220 when the contract content of the B-CAS card inserted in the card slot is changed. In short, a warning screen may be output when a state change of the B-CAS card occurs.

4-13
In the first embodiment, the BD recorder 100 determines the presence / absence of a pay contract for each B-CAS card based on the presence / absence of energization control information for each B-CAS card. However, it is not necessarily limited to such a configuration. For example, the BD recorder 100 actually executes a descrambling process of a pay program using a B-CAS card to determine whether or not there is a pay contract, and refers to the result (success / failure) of the descrambling process. It can be determined whether or not the B-CAS card has a pay broadcast contract. That is, when the descrambling process is actually successful, it can be determined that the B-CAS card has concluded a pay broadcast contract. When the descrambling process fails, the B-CAS card has concluded a pay broadcast contract. It can be judged that there is no.

4-14
In the first embodiment, a paid channel contract for the mini-shared B-CAS card inserted in the B-CAS card slot 130 is made, and a charge for the shared B-CAS card inserted in the B-CAS card slot 120 is made. When no channel contract is made, a screen prompting the user to conclude a pay channel contract for the shared B-CAS card inserted in the B-CAS card slot 120 is displayed (see FIG. 20). However, it is not necessarily limited to such an example. For example, a paid channel contract is made for the shared B-CAS card inserted into the B-CAS card slot 120, and a paid channel contract is not made for the mini shared B-CAS card inserted into the B-CAS card slot 130. In this case, a screen that prompts the user to conclude a pay channel contract for the mini-shared B-CAS card inserted in the B-CAS card slot 130 may be displayed. Alternatively, regardless of whether or not there is a paid channel contract for each B-CAS card, a change in the status of each B-CAS card (for example, the contract status of the paid channel) is detected by the LSI corresponding to each B-CAS card. At this time, the LSI 170 may display a screen that prompts the user to conclude a pay channel contract for each B-CAS card.

4-15
In the first embodiment, the BD recorder 100 actually performs descrambling on the broadcast of each channel when confirming the reception status using each B-CAS card. However, it is not necessarily limited to such a configuration. For example, the reception status of each B-CAS card may be confirmed by referring to energization control information stored for each B-CAS card.

4-16
In the first embodiment, the BD recorder 100 displays a list of reception conditions as shown in FIG. However, it is not necessarily limited to such a configuration. For example, the configuration may be such that the confirmation result code included in the reception confirmation result log file is displayed. In this case, the call center telephone number may also be displayed on the screen. The user can know what kind of pay broadcast contract each B-CAS card has concluded by calling the call center and telling the operator the code displayed on the screen. Further, for example, LEDs and LCDs are arranged in the vicinity of each B-CAS card slot of the BD recorder 100, and the LEDs and LCDs in the vicinity of the B-CAS card slot in which the B-CAS card for which a pay broadcast contract is made are inserted. May be lit. Also by this, the user can determine which B-CAS card has a pay broadcast contract by simply looking at the appearance.

In the first embodiment, the shared B-CAS card used for time shift recording is only the mini shared B-CAS card inserted into the B-CAS card slot 130, and the card information of the mini shared B-CAS card. The card information screen as shown in FIG. 9 is displayed. However, it is not necessarily limited to such a configuration. For example, when there are a plurality of shared B-CAS cards used for time shift recording, a screen as shown in FIG. 45 may be displayed as the card information screen. By displaying a screen as shown in FIG. 45, even if a pay broadcast contract is concluded for one B-CAS card, only 3 channels of pay broadcast can be time-shift recorded, and time shift recording of 4 channels or more Can be notified to the user that it is necessary to conclude a pay broadcast contract for other shared B-CAS cards. Also, the warning screen as shown in FIG. 45 may be output for the first time when the recording setting for four or more channels is actually performed as the recording setting.

4-18
In the first embodiment, when the mini shared B-CAS card inserted into the B-CAS card slot 130 is replaced with another mini shared B-CAS card, a warning screen as shown in FIG. 30 is displayed. I decided to display it. However, it is not necessarily limited to such a configuration. For example, a warning screen as shown in FIG. 46 may be displayed. The warning screen shown in Fig. 46 includes a link to the confirmation screen for time-shift recording (“Do you want to confirm the time-shift recording setting?“ Yes ”/“ No ””). By selecting the link to the recording confirmation screen ("Yes"), the time shift recording setting can be easily redone. For example, it is assumed that the mini shared B-CAS card before the replacement has signed a pay broadcast contract, but the mini shared B-CAS card after the replacement has not signed a pay broadcast contract. It is assumed that a pay channel for pay broadcasting is set as the time shift recording setting. In such a case, nothing is recorded as time-shift recording, and it is necessary to redo the recording settings for time-shift recording. The warning screen displayed when the B-CAS card is exchanged includes a link to the time-shift recording setting screen, so that the user can set the recording setting when the B-CAS card is exchanged. Can be easily changed. The screen shown in FIG. 46 may be displayed when a change in the contract state of the B-CAS card is detected (when a new contract EMM is received). This is because even when the contract state of the B-CAS card changes, the broadcast program that can be received by the B-CAS card changes, and it may be necessary to change the time shift recording setting.

4-19
Further, the BD recorder 100 according to the first embodiment may further display a warning screen for prompting the user to confirm the setting of time shift recording when receiving a broadcast mail. This is because broadcast mail is often sent when a paid contract is concluded for a shared B-CAS card, so it is often better to review the recording status of time-shift recording according to changes in the contract status. .

4-20
Further, the BD recorder 100 according to the first embodiment performs the descrambling process on the broadcast program received via the antenna when viewing confirmation is performed. However, it is not necessarily limited to such an example. For example, a method of transmitting a contract confirmation command to each B-CAS card and analyzing the response to confirm which channel can be viewed may be used.

4-21
Further, the BD recorder 100 according to the first embodiment outputs a screen showing the state of each B-CAS card as shown in FIGS. 8 and 9 at the time of initial setting (purchase setting). However, it is not necessarily limited to such an example. For example, a screen as shown in FIG. 47 or 48 may be output. 47 and 48 are schematic views showing display screens at the time of initial setting (purchase setting).

  The screen shown in FIG. 47 displays information regarding the shared B-CAS card inserted into the B-CAS card slot 120. In this screen, the message “In addition, in order to perform time-shift recording on pay broadcast channels at the same time, a subscription contract with the time-shift recording card [2] is required” is displayed. That is, this screen shows information related to the pay contract of the B-CAS card for time shift recording in the screen showing the information of the B-CAS card for normal recording.

  On the other hand, the screen shown in FIG. 48 displays information related to the mini-shared B-CAS card inserted in the B-CAS card slot 130. In this screen, the message “In addition, a normal subscription card [1] is required for normal recording of pay broadcast channels at the same time” is displayed. That is, this screen shows information related to the pay contract for the B-CAS card for normal recording on the screen showing the information about the B-CAS card for time-shift recording.

  Thus, in this example, it is a screen which shows the information of some B-CAS cards among a plurality of B-CAS cards, and pay broadcasting of B-CAS cards other than the some B-CAS cards Output a screen containing a message about the contract. Thereby, in order to record a pay broadcast program, it is possible to notify the user that it is necessary to conclude a pay broadcast contract for each B-CAS card.

4-22
Further, the BD recorder 100 according to the first embodiment outputs a screen showing the state of each B-CAS card as shown in FIGS. 8 and 9 at the time of initial setting (purchase setting). However, it is not necessarily limited to such an example. For example, a screen as shown in FIG. 49 may be output. This screen is a characteristic of the shared B-CAS card (representative card) inserted in the B-CAS card slot 120, and “This card ID number is acquired or used for data broadcasting.” Is included. That is, this screen shows that the shared B-CAS card inserted into the B-CAS card slot 120 is a representative card, and that the card ID of the representative card is acquired or used in data broadcasting. . Thus, the user can easily understand that the shared B-CAS card inserted into the B-CAS card slot 120 is a representative card and the characteristics of the representative card. Further, in the screen showing the information of the B-CAS card shown in FIG. 49, in addition to the information of one of the plurality of B-CAS cards (here, the representative card), B other than the card (representative card) is displayed. -A message regarding the paid broadcasting contract for the CAS card, “In addition, in order to time-shift record the paid channel at the same time, subscriptions for the time-shift recording cards (2), (3) and (4) are required. "It is included. Thereby, the user can grasp | ascertain the condition regarding a pay broadcast contract also about cards other than B-CAS card by which detailed information is displayed on a screen.

4-23
Further, the BD recorder 100 according to the first embodiment outputs a screen as shown in FIG. 8 or 9 at the time of initial setting (purchase setting). However, it is not necessarily limited to such an example. For example, after completion of the initial setting (purchase setting), it may be displayed when a transition is made from the menu screen to a mode for displaying information on each B-CAS card.

4-24
In addition, the following operation may be performed with respect to the operation when the B-CAS card is inserted in the BD recorder 100 according to the first and second embodiments. The operation will be described with reference to FIG. FIG. 50 is a flowchart for explaining the operation when the B-CAS card is inserted. Here, the operation when a B-CAS card is inserted into the B-CAS card slot 120 into which a shared B-CAS card should be inserted will be described.

  A user can insert a B-CAS card into the B-CAS card slot 120. When the B-CAS card is inserted (S1700), the LSI 170 determines whether or not the B-CAS card inserted into the B-CAS card slot 120 is a shared B-CAS card (S1710). If it is determined that the card is a shared B-CAS card, the LSI 170 proceeds to the next process (S1720).

  On the other hand, if it is determined that the B-CAS card inserted into the B-CAS card slot 120 is not a shared B-CAS card, the LSI 170 determines that the B-CAS card inserted into the B-CAS card slot 120 is a terrestrial digital camera. It is determined whether the card is a dedicated B-CAS card (S1730).

  If it is determined that the card is not a terrestrial digital B-CAS card, the LSI 170 proceeds to the next process (S1740). The reason for this configuration will be described next.

  As B-CAS cards, there are B-CAS cards for sales staff (white) and B-CAS cards for development staff (yellow) in addition to shared B-CAS cards and terrestrial digital B-CAS cards. These white cards and yellow cards are configured so that various broadcast programs can be descrambled depending on the purpose of use. Therefore, when these white cards or yellow cards are inserted into the B-CAS card slot where the shared B-CAS card should be originally inserted, the process should proceed to the next process without outputting a warning screen or the like. It is. Therefore, if it is determined in step S1730 that the card is not a terrestrial digital B-CAS card, the LSI 170 proceeds to the next process. By looking at a specific digit of the card ID of the B-CAS card, the LSI 170 can determine whether the B-CAS card is a white card or a yellow card.

  On the other hand, if it is determined in step S1730 that the card is a terrestrial digital-only B-CAS card, the LSI 170 determines whether the current setting is the initial setting (purchase setting) (S1750). If it is determined that the initial setting (purchase setting) is not in progress, the LSI 170 outputs a warning screen (S1760), and proceeds to the next processing (S1770). On the other hand, if it is determined that the initial setting (purchase setting) is in progress, the LSI 170 outputs a warning screen (S1780), returns to step S1710, and another B-CAS card is inserted into the B-CAS card slot 120. The same process is repeated until the card is replaced with a B-CAS card.

  As described above, in this configuration, when it is detected that the terrestrial digital B-CAS card is inserted into the B-CAS card slot into which the shared B-CAS card is to be inserted, an initial setting (purchase setting) operation is performed. If it is not in progress, the process proceeds to the next process. If the initial setting (purchase setting) is in progress, the B-CAS card inserted in the B-CAS card slot is replaced with another B-CAS card. Unless it is, it does not move to the next process. Accordingly, the BD recorder 100 having this configuration can insert a correct B-CAS card into the B-CAS card slot at the time of initial setting (purchase setting).

4-25
In the second embodiment, the BD recorder 100 displays a screen prompting the user to put a sticker on each B-CAS card during the initial setting operation. However, it is not necessarily limited to such a configuration. For example, when the replacement of the B-CAS card is detected, a screen that prompts the user to attach a sticker may be displayed. In short, any timing may be displayed as long as the user can be prompted to put a sticker on each B-CAS card.

4-26
In the operation shown in the flowchart of FIG. 4 in the first embodiment, only when a B-CAS card is inserted in all of the front card slot 120 and the rear card slots 130 to 150 (YES in S230, in S280). YES), it is assumed that the process proceeds to the step of displaying the card status confirmation screen (FIGS. 8 and 9) (S290, S300). However, it is not limited to such control. Even when the B-CAS card is not inserted in some slots, the control may be performed so as to proceed to the step (S300) of displaying the card status confirmation screen. In this case, when the insertion of the B-CAS card is not detected in some of the slots, a screen showing a warning that a malfunction may occur in the viewing / recording function as shown in FIG. It is preferable to proceed to the step of displaying a card status confirmation screen (S300).

4-27
In the description of the operation shown in the flowchart of FIG. 10 in the first embodiment, at the initial setting of the BD recorder 100, a pay channel descrambling process is executed using a B-CAS card capable of descrambling pay broadcasting. (S410) Thereby, the free viewing period of the B-CAS card was automatically started. However, the pay channel descrambling process is first executed using the mini-shared B-CAS card (B-CAS card capable of descrambling pay broadcasting in time shift recording) inserted into the B-CAS card slot 130. The timing is not limited to the initial setting of the BD recorder 100. For example, during the maintenance period of the BD recorder 100, the pay-channel descrambling process may be executed using the B-CAS card, and the free viewing period of the B-CAS card may be automatically started.

4-28 (Automatic mapping of time-shift recording channels)
The BD recorder 100 of each of the above embodiments may further include an automatic mapping function that automatically assigns a recording channel set by a user for time shift recording to a plurality of shared B-CAS cards. . Hereinafter, two examples of the automatic mapping function of the time shift recording channel will be described.

(1) First example (combination of red card and red card)
Here, it is assumed that the BD recorder 100 has a configuration as shown in FIG. In the configuration shown in FIG. 52, B-CAS cards compatible with BS, CS, and terrestrial digital broadcasting can be inserted into two of the three B-CAS card slots 130, 140b for time-shift recording. Card slot. The automatic mapping function of the recording channel for the two B-CAS cards inserted in these B-CAS card slots 130 and 140b will be described.

  The user can set up to six channels for time shift recording on the recording channel setting screen as shown in FIG. 52B. When a channel is set by the user on this setting screen, the set channel is a B-CAS card inserted into the B-CAS card slot 130 and a B-CAS card inserted into the B-CAS card slot 140b. Is automatically assigned to any of the above. The automatic mapping operation will be described below with reference to the flowcharts of FIGS. 53A to 53C.

  The LSI 170 includes a B-CAS card (hereinafter referred to as “card (1)”) inserted into the B-CAS card slot 130 and a B-CAS card (hereinafter referred to as “card (2)”) inserted into the B-CAS card slot 140b. Card information and setting channel information are acquired from the above (S2000). The LSI 170 acquires the card contract status from the acquired card information (S2010). Specifically, the LSI 170 determines the business entity (broadcasting company) from the business entity identification code of the energization control. Further, the LSI 170 confirms the contract status based on the energization start reference date. Specifically, if the energization start reference date is later than the current date, “contract is valid”. When the current situation is “free trial period”, it is “contracted”, and when it is provisional viewing, “not contracted”. If the card information cannot be obtained, “No contract” is set.

  Next, the LSI 170 determines whether one channel set by the user is a BS broadcast or a CS broadcast (S2020). When one channel set by the user is either BS broadcast or CS broadcast, broadcast of the channel set by the user is received by one of the tuners 133 to 135 and the tuners 143b to 145b. (S2030). The LSI 170 determines whether the channel set by the user is charged or free (S2040, S2050). For example, if SDT free_CA_mode = 1, it is determined that the channel is a pay channel, and if not, it is determined that the channel is a free channel.

  In the case of a paid channel (YES in S2050), the service ID (information specifying the channel) and the business entity are associated and recorded in the channel list based on the CA service description (S2060). The channel list is held in the HDD 180, for example.

  The above processing (S2020 to S2060) is performed for all channels set by the user (S2070).

  When the processing is completed for all channels set by the user, the information in the channel list is sorted. Here, sorting is performed so that the pay broadcast channel is higher than the free broadcast channel (S2080). This is because the pay broadcast channel is preferentially processed in the subsequent processing.

  After sorting the channel list, counters n1 and n2 indicating the number of channels assigned to the cards (1) and (2) are set to 0 (S2100 in FIG. 53B). Referring to the channel list, a channel to be assigned to the card (hereinafter referred to as “target channel”) is determined (S2110). At this time, since the pay broadcast channel is sorted higher than the free broadcast channel in the channel list, the pay broadcast channel is selected as the target channel before the free broadcast channel. It can be assigned to a card.

  The LSI 170 determines whether the value of the counter n1 is 3 or more (S2120). That is, it is determined whether or not there is an empty channel in the card (1). When the value of the counter n1 is 3 or more, it means that there is no empty channel in the card (1), so the LSI 170 assigns the target channel to the card (2) (S2130). Then, the value of the counter n2 is counted up (S2140).

  On the other hand, when the value of the counter n1 is less than 3, the LSI 170 further determines whether or not the value of the counter n2 is 3 or more (S2120). Here, both the values of the counter n1 and the counter n2 being less than 3 mean that there are empty channels in both the card (1) and the card (2), and channels are allocated to both cards. It becomes possible.

  When the value of the counter n2 is less than 3 in step S2150, the LSI 170 determines whether or not the target channel is a free broadcast channel (S2200 in FIG. 53C). When it is not a free broadcast channel, that is, when it is a pay broadcast channel, it is determined whether or not the card (1) already has a contract for a channel of the same business entity as the business entity of the target channel (S2260). If there is a contract for a channel of the same business entity, the LSI 170 assigns the target channel to the card (1) (S2270), and counts up the counter n1 (S2280).

  On the other hand, if the card (1) does not have a contract for the channel of the same entity as the entity of the target channel, the LSI 170 allocates the target channel to the card (2) (S2290) and counts up the counter n2 (S2300). .

  In step S2200, when the channel is a free broadcast channel, the LSI 170 determines whether or not the card (1) has a paid channel contract (S2210). When there is no paid channel contract in the card (1), the LSI 170 assigns the target channel to the card (1) (S2220), and counts up the counter n1 (S2230). On the other hand, when there is a pay channel contract in the card (1), the LSI 170 assigns the target channel to the card (2) (S2240), and counts up the counter n2 (S2250).

  When the target channel is assigned to the card (1) or the card (2) as described above, the control of the LSI 170 returns to step S2180 in the flowchart of FIG. 53B. The above process is repeated until there are no more empty channels in the cards (1) and (2).

  In general, one business entity may provide a plurality of paid channels. If multiple pay channels of such an entity are allocated across multiple cards, it may be necessary to conclude a contract for each contract card, which is detrimental to the user. Therefore, as described above, by assigning channels to cards based on the contract status of the cards and the attributes of the set channels, a plurality of channels of one business entity that provides pay broadcasting can be assigned to the cards (1) and (2 ) Can be automatically assigned to either of them. Thereby, the convenience of the user can be achieved.

(1) Second example (combination of red card and blue card)
Here, an automatic mapping function for two B-CAS cards inserted in two B-CAS card slots 130 and 140 for time shift recording in a BD recorder having the configuration shown in FIG. 54B will be described. The B-CAS card slot 130 can accept BS, CS, and B-CAS cards compatible with digital terrestrial broadcasting, but the B-CAS card slot 140 is compatible with digital terrestrial broadcasting only. Only cards can be inserted.

  The B-CAS card inserted into the B-CAS card slot 140 is compatible only with terrestrial digital broadcasting. Therefore, in this example, on the recording channel setting screen as shown in FIG. 54, the time-shift recording channel can be set up to 6 channels at the maximum, but only BS channel and CS broadcast can be set up to 3 channels at the maximum. It is like that.

Hereinafter, the automatic mapping operation of this example will be described with reference to the flowcharts of FIGS. 53A and 53D. Hereinafter, the B-CAS card inserted into the B-CAS card slot 130 is referred to as “card (1)”, and the B-CAS card inserted into the B-CAS card slot 140 is referred to as “card (2)”.
Also in this example, according to the setting on the setting screen, processing such as acquisition of card information and the like, determination of a pay channel, sorting of a channel list, and the like (steps S2000 to S2060 in the flowchart of FIG. 53A) are performed.

  After the channel list is sorted, the values of counters n1 and n2 indicating the number of channels assigned to the cards (1) and (2) are set to 0 (S2500 in FIG. 53D). With reference to the channel list, a channel to be assigned to the card (hereinafter referred to as “target channel”) is determined (S2510). At this time, since the pay broadcast channel is sorted higher than the free broadcast channel in the channel list, the pay broadcast channel is selected as the target channel before the free broadcast channel. It can be assigned to a card.

  The LSI 170 determines whether the target channel is BS broadcasting or CS broadcasting (S2520). When the target channel is BS broadcast or CS broadcast, the LSI 170 assigns the target channel to the card (1) (S2530), and counts up the value of the counter n1 (S2540). The reason why the channel of BS broadcasting or CS broadcasting is assigned to the card (1) is because the card (2) is a B-CAS card that supports only terrestrial digital broadcasting.

  On the other hand, when the target channel is neither BS broadcast nor CS broadcast, the LSI 170 further determines whether or not the value of the counter n2 is 3 or more (S2550). Here, both of the values of the counter n1 and the counter n2 being less than 3 mean that there is an empty channel in the card (2), and means that a channel can be assigned to the card (2). .

  When the value of the counter n2 is less than 3 in step S2550, that is, when there is an empty channel in the card (2), the LSI 170 assigns the target channel to the card (2) (S2580) and counts up the value of the counter n2. (S2590). On the other hand, when the value of the counter n2 is not less than 3, that is, when there is no empty channel in the card (2), the LSI 170 assigns the target channel to the card (1) (S2560) and counts up the value of the counter n1 (S2570). ).

  Then, the above process is repeated until there are no empty channels in the cards (1) and (2) (S2600).

By assigning channels to cards as described above, a time shift is achieved with respect to a combination of a B-CAS card compatible with BS broadcasting, CS broadcasting, and terrestrial digital broadcasting, and a B-CAS card compatible only with terrestrial digital broadcasting. Recording channels can be automatically assigned appropriately.
In this example (a combination of a red card and a blue card), it is not always necessary to sort such that the pay broadcast channel is higher than the free broadcast channel. This is because, regardless of the order in which the channels are arranged, the pay broadcast channel is preferentially assigned to the red card, while the free broadcast channel is preferentially assigned to the blue card.

4-29
In the time-shift recording reservation operation described in section “1-4-2-2”, when a channel is set on the reservation screen shown in FIG. 12, viewing confirmation is performed on the set channel (section “1”). -4-10 ”), if the set channel cannot be received, the cause of the reception failure (paid channel not subscribed, antenna not connected, B− A message or an image indicating that the CAS card has not been inserted / incorrectly inserted may be displayed. For example, as shown in FIG. 55, an icon 320 indicating the cause of reception failure (uncontracted) may be displayed in the vicinity of the channel information.

4-30
When the “viewing item” in the recording reservation status list information described with reference to FIG. 34 is “not contracted”, the LSI 170 displays a message indicating a warning when the power of the BD recorder 100 is turned on. An image may be displayed on the screen. For example, a message such as “No contract for XXX channel” may be displayed in a pop-up on the screen.
