Description

recording device

technical field

The present invention relates to a recording device for recording content data such as program data representing the content of a broadcast program on a recording medium such as a Blu-ray disc.

Background technique

Currently, video recording devices (recording devices) for recording programs broadcast by television broadcasting are widespread. Some recording devices record program data representing content such as program video or audio on a built-in recording medium such as a hard disk, and some recording devices record program data on a removable recording medium such as a detachable optical disc. In the case of recording in a recording device using a built-in recording medium, the program can only be played back using the recording device that has recorded the recording. In addition, if the program data is continuously saved without being deleted, the recording capacity will be insufficient, so Preservation of program data is more difficult. Therefore, in order to play back the program by other playback devices, or to save the program data, the program data is dubbed from the built-in recording medium to a removable recording medium. However, the transcribing of program data is very cumbersome, and for users who are not used to operating electronic devices, the transcribing operation is relatively difficult.

Patent Document 1 describes a video recording device that uses a hard disk to perform video recording for a certain period of time, associates a program to be dubbed with an ID identifying a removable recording medium in advance, and when the recording medium is installed, The program data of the program associated with the ID of the recording medium among the recorded programs is dubbed. With this technology, if the operation of registering the program to be dubbed is performed in advance, the dubbing can be easily performed only by attaching a removable recording medium to the video recording device.

Dubbing is not required in recording devices that record program data directly on a portable recording medium. When a plurality of users use the same video recording device at home, each user has his own recording medium, so that each user can record his favorite program on his own recording medium. When the user owns a plurality of video recording devices, it is also possible to record video on one recording medium with the plurality of video recording devices. However, recording reservation information is stored in the recording device when making a recording reservation. Therefore, if a recording medium other than the recording medium used for recording is installed by mistake, program data may be recorded on the recording medium. In addition, in the case of using a plurality of video recording devices, it is very troublesome to set recording reservations for each video recording device.

Patent Document 1 also describes a technique of recording recording reservation information on a portable recording medium, and performing recording based on the information recorded on the recording medium. With this technique, recording is performed on the same recording medium based on the reservation information recorded on the recording medium. In addition, recording can be performed on the same recording medium even when another recording device is used as long as recording reservation is set in one recording device.

Patent Document 2 describes an optical disc playback device capable of loading a plurality of optical discs as recording media and reproducing content recorded on a selected one of the optical discs. With this technology, since a plurality of optical discs of the same type can be placed on standby in the device in advance, even if multiple users at home use the same video recording device, each user can save the need for each user to use the device every time. It is troublesome to exchange the recording medium installed by other users with your own recording medium.

In the digital tuner 21, a digital broadcast broadcast signal is input to the digital tuner 21 from the broadcast input unit 31, and the selected channel, that is, the broadcast signal of a specific frequency band is converted into MPEG (Moving Picture Experts Group)-2TS (Transport Stream ) and other digital stream data. In the encoder 22, a video signal and an audio signal are input from the signal input unit 32 to the encoder 22, and the video signal and the audio signal are encoded into digital stream data such as MPEG-2PS (Program Stream) or MPEG-2TS. In addition, the backend unit 20 includes a stream processing unit 23 , and the digital tuner 21 and the encoder 22 are connected to the stream processing unit 23 . In the stream processing unit 23, stream data is input from the digital tuner 21 and the encoder 22 to the stream processing unit 23, and data processing on the stream data such as descrambling for digital broadcasting is performed.

The stream processing unit 23 is connected to the system bus in the backend unit 20 . In addition, on the system bus, there are connected a recording/playback control unit 24 composed of a computing unit that performs calculations, a control memory 25 as a volatile memory, a storage memory 27 as a nonvolatile memory, and a convection memory. Data is decoded by decoder 28. In addition, an image processing unit 29 is connected to the decoder 28 . The recording/playback control unit 24 performs a process of controlling input and output of data between components connected to the system bus. In addition, a remote control receiving unit 33 outside the rear end 20 is connected to the recording/reproducing control unit 24. various instructions from the operator. In addition, the recording device 1 may further include a digital interface such as Ethernet (registered trademark) for receiving streaming data from an external device such as a tuner. This digital interface is connected to the stream processing unit 23 .

The control memory 25 stores temporary information accompanying calculations performed by the stream processing unit 23 or the recording/reproducing control unit 24 or the like. The storage memory 27 stores information to be stored, such as a control program necessary for the operation of the recording/reproducing control unit 24 and reservation information in which recording reservation contents are recorded. The decoder 28 decodes the stream data into a video signal and an audio signal, and inputs the video signal and the audio signal to the image processing section 29 . The image processing unit 29 executes image processing such as pixel interpolation and color adjustment on the video signal. A signal output unit 34 outside the rear end unit 20 is connected to the image processing unit 29 , and video signals and audio signals are output from the signal output unit 34 to the video display device 4 .

And, on the system bus in the rear end portion 20, interface portions 26 such as SATA (Serial Advanced Technology Attachment: Serial Advanced Technology Attachment) are connected, and the hybrid drive portion 10 outside the rear end portion 20 is connected to the interface portion 26. The rear end unit 20 exchanges data with the hybrid drive unit 10 via the interface unit 26 .

The hybrid drive unit 10 includes an interface unit 14 such as SATA connected to the rear end unit 20 , an optical disc drive 11 , a storage unit 12 for storing data, and a drive control unit 13 for controlling the operations of the optical disc drive 11 and the storage unit 12 . The hybrid drive unit 10 exchanges data with the rear end unit 20 via the interface unit 14 . An optical disc 6 such as a DVD is loaded in the optical disc drive 11 , and data from the loaded optical disc 6 is read and recorded on the optical disc 6 .

The storage unit 12 is constituted by a nonvolatile memory such as a flash memory or a hard disk. FIG. 3 is a schematic diagram showing the internal structure of the storage unit 12 . The storage unit 12 includes a management area for storing information for managing storage contents of the storage unit 12, and a plurality of storage areas for storing program data, including a first area, a second area..., an n-th area, and a spare area. constitute. Here, n is a positive integer and is the number of optical discs 6 registered in the recording device 1 . The number of registered optical discs 6 is determined by the user. The storage unit 12 divides the storage area according to the determined value of n. In addition, an appropriate value of n may be determined in advance, and the storage area of the storage unit 12 may be divided into a plurality of storage areas of the management area, the first to nth areas, and the spare area in advance at the time when the recording device 1 is shipped.

Among the storage areas of the storage unit 12 , the first to nth areas are storage areas that are respectively associated with specific optical discs in advance and are used to store data corresponding to the corresponding optical discs. For example, a specific optical disc 61 is associated with the first area, and a specific optical disc 62 is associated with the second area. At the time when the video recording device 1 was shipped, none of the areas corresponded to an optical disc. In order to use the recording device 1 , it is necessary to perform a process of associating an optical disc owned by the user with any storage area and registering it. In addition, the spare area is a storage area for storing other data, or a storage area used when increasing the number of registered optical discs 6 .

The management area of storage part 12 is shown in Figure 3, comprises: the management area management part that stores the information that is used to manage the management area; A first area management unit, a second area management unit . . . , an n-th area management unit, and a spare area management unit separately manage information. The management area stores the number of entries and allocation area information. The number of entries indicates the number of divisions of the storage area of the storage unit 12. The allocation area information indicates the allocation of the first to nth area management units and the spare area management units respectively in the management area. The assigned zone address.

The first area management unit stores an entry number indicating the number of the first area, an allocation flag indicating whether or not an optical disc actually corresponds to the first area, and a medium ID (medium information) for identifying the corresponding optical disc. In addition, the first area management unit stores: allocated area information indicating an area address allocated to the first area in the storage area of the storage unit 12; media key information used for Information used for copy guidance of the optical disc; mapping information indicating the distribution state of data related to the first area; and disc color information indicating the color of the optical disc 6 registered in the recording device 1 .

The media ID and media key information are pre-recorded information on the optical disc, and are unique to each optical disc. When the video recording device 1 is shipped, since the first area is not associated with the optical disc 61, the allocation mark indicates that no optical disc is associated, and the media ID and media key information specific to the specific optical disc 61 have not yet been stored. The mapping information indicates at which address the data stored in the first area and the data recorded on the optical disc 61 corresponding to the first area are distributed between the first area and the optical disc 61 . The disc color information indicates in what color information on the disc 61 corresponding to the first area is displayed on the video display device 4 . In addition, the disc color information is also stored in the disc 61, and even if the content in the storage unit 12 is deleted by mistake, the registered content can be saved. In addition, when the optical disc 61 is used by another recording device, the same registered content can be used. The same information is also stored in each of the second to nth area management units.

FIG. 4 is a schematic diagram showing an example of a login screen displayed when the optical disc 6 is registered.

When the optical disc 6 is mounted, a login screen is automatically displayed on the video display device 4 or, for example, by receiving an operation to start the login from the remote controller 5 , and displayed on the video display device 4 . On the registration screen, the registration number and disc color (identification information) set to the mounted optical disc 6 are displayed, and can be selected by the remote controller 5 or the like, for example. The registration numbers are numerical values from 1 to 8 assigned to the mounted optical discs 6 . Since registration numbers are not assigned repeatedly to the registered optical discs 6, the numbers already assigned to the optical discs 6 are not displayed on the registration screen. The first to nth areas of the storage unit 12 are associated with the registration numbers registered from the login screen. For example, the optical disk 61 whose registration number "1" is set on the registration screen corresponds to the first area, and the optical disc 62 whose registration number "2" is set corresponds to the second area.

In addition, the disc color is red, green, yellow, blue, etc. assigned to the disc 6, for example, the user selects the same (similar) color as the label of the disc 6 or the color the user likes. The selected disc color is stored as the above disc color information. The details will be described later, but when displaying information on the mounted optical disc 6 on the video display device 4, the screen display is performed in the disc color set on the login screen. Thus, the user can grasp the type of the optical disc 6 mounted on the video recording device 1 based on the color. Alternatively, when the optical disc 6 is mounted, the recording device 1 may automatically set a free registration number and disc color. In addition, the name of the optical disc to be registered may be inputted on the login screen.

Next, the processing performed by the video recording device 1 configured as described above will be described.

When the user designates the value of the number n of optical discs to be registered, the video recording device 1 performs a process of dividing the storage area of the storage unit 12 according to the value of n. FIG. 5 is a flowchart showing the procedure of dividing the storage area of the storage unit 12 . The recording/playback control unit 24 displays on the video display device 4 a acceptance screen for accepting designation of the number of optical discs 6 that can be registered in the recording device 1 . After that, the remote control receiving unit 33 receives a signal from the remote control 5 that the user has performed a predetermined operation, and the recording/reproducing control unit 24 accepts designation of the number of discs that can be registered (S11). In addition, the registration number displayed on the registration screen shown in FIG. 4 is determined according to the number of sheets accepted in step S11. For example, when eight discs that can be registered are designated, the registration numbers that can be selected on the registration screen are 1 to 8.

The recording/playback control unit 24 sets the number of entries by storing the value of the designated number of sheets as the number of entries n in the management area management unit of the storage unit 12 (S12). Next, the recording/playback control section 24 ensures the first to nth area management sections and the spare area management section in the management area of the storage section 12, and stores the allocation area information representing the area address assigned to each in the management area management area. In the section, the first area management section, the second area management section..., the nth area management section, and the spare area management section are set (S13). Next, the recording/playback control section 24 divides the storage area other than the management area of the storage section 12 into (n+1) storage areas, and assigns the area addresses representing the respective allocations to the first to nth areas and the spare area. The area information is stored in each of the first to nth area management units and the spare area management unit, thereby setting the first to nth areas and the spare area (S14). The recording device 1 ends the process of dividing the storage area of the storage unit 12 as described above.

FIG. 6 is a flowchart showing the procedure of processing performed by the recording device 1 after the optical disc 6 is loaded in the optical disc drive 11 .

When an optical disc is loaded into the optical disc drive 11 by the user's operation, the drive control unit 13 causes the optical disc drive 11 to read the information recorded on the predetermined position in the optical disc 6, thereby reading the medium ID of the optical disc, and The media ID is input from the interface unit 14 to the rear end unit 20 . Recording/playback control section 24 is stored in any management section in the 1st～n area management section of memory section 12 by the medium ID of judging read, thus judges whether installed optical disc 6 is registered (S201 ). When there is no storage medium ID in the storage unit 12 and the disc is not registered (S201: No), the recording/playback control unit 24 determines whether the disc 6 has been formatted based on the data read by the disc drive 11 from the disc 6 (S202). ). In step S202, determination is made based on, for example, the volume descriptor. When the optical disc 6 is formatted (S202: YES), the recording/reproduction control unit 24 determines whether the optical disc 6 is for playback only based on the data read from the optical disc 6 by the optical disc drive 11 (S203).

When the optical disc 6 is not for playback only (S203: No), the recording/playback control unit 24 determines whether or not a format instruction for the optical disc 6 has been accepted (S204). For example, the recording/playback control unit 24 transmits a video signal for an acceptance screen for accepting an instruction to format the optical disc 6 from the signal output unit 34 to the video display device 4 via the decoder 28 and the image processing unit 29, thereby The video display device 4 is caused to display an acceptance screen for accepting a formatting command. The user who confirmed the acceptance screen inputs a formatting command by operating the remote controller 5 when formatting is to be performed.

When the remote controller receiving unit 33 receives a predetermined signal transmitted from the remote controller 5 that has received a predetermined operation from the user, and thus accepts the formatting instruction of the optical disc 6 (S204: Yes), or in step S202 When the optical disc 6 is not formatted (S202: No), the recording/reproduction control unit 24 causes the drive control unit 13 and the optical disc drive 11 to format the optical disc 6 (S205).

When the format command of the optical disc 6 has not been received (S204: No), the recording/reproduction control unit 24 determines whether or not the registration command of the optical disc 6 has been received (S206). For example, the recording/playback control unit 24 causes the video display device 4 to display an acceptance screen for accepting a login command, and accepts an instruction whether to register the optical disc 6 through the remote control receiving unit 33 . In addition, processing may be performed such that the video display device 4 displays an acceptance screen in which the acceptance screen for accepting the formatting command and the acceptance screen for accepting the login command are combined into one.

When step S205 ends, or when an optical disc registration command is accepted in step S206 (S206: YES), the recording/playback control unit 24 determines that the storage unit 12 is based on information stored in the management area of the storage unit 12. Whether there is a storage area that does not correspond to an optical disc in the first to nth areas of the storage area (S207). If there is no storage area not compatible with an optical disc (S207: No), the recording/reproduction control unit 24 determines whether or not a command to cancel the registration and create a storage area not compatible with an optical disc has been accepted (S208). For example, the recording/playback control unit 24 displays an accepting screen for accepting a command to cancel the registration of an already registered optical disc, after notifying that the new registration of the optical disc cannot be performed. The user uses the remote controller 5 to instruct which optical disc to cancel the registration, and the recording/playback control unit 24 receives the cancellation command through the remote controller receiving unit 33 .

When the instruction to cancel the registration is accepted (S208: Yes), the recording/playback control unit 24 cancels by causing the drive control unit 13 to delete the information unique to one optical disc stored in the management area of the storage unit 12. Processing of registration of one optical disc (S209). For example, when the registration of the optical disc 61 corresponding to the first area of the storage unit 12 is to be canceled, the registration is canceled by deleting the media ID and media key information stored in the first area management unit of the storage unit 12. processing. In addition, at this time, the allocation flag stored in the first area management unit is rewritten into a flag indicating that the optical disk is not supported.

In step S207, when there is a storage area not corresponding to an optical disk (S207: YES), or when step S209 is completed, the recording/playback control unit 24 displays the login screen shown in FIG. 4 (S210). At this time, the registration number on the registration screen is displayed according to the number of storage areas that do not correspond to the optical disc. For example, when the storage unit 12 is divided into the first to eighth areas, and the six areas correspond to optical discs with registration numbers "1" to "6", "7" and "7" are displayed on the registration screen. 8” registration number.

After the login screen is displayed, the recording/playback control unit 24 performs a process of registering the optical disc 6 loaded in the optical disc drive 11 by associating it with any one of the non-disc-compatible storage areas (S211). For example, when the optical disc 61 is associated with the first area of the storage unit 12, the media ID and media key information read from the optical disc 61 loaded in the optical disc drive 11 are stored in the first area of the storage unit 12. in the management department. In addition, the disc color set on the login screen is stored in the disc 61 and the first area management unit of the storage unit 12, respectively. Then, the allocation flag stored in the first storage management unit is rewritten into a flag indicating that the optical disk is supported. In step S201, when the optical disc has been registered (S201: Yes), or when step S211 has ended, the recording/playback control unit 24 starts accessing the optical disc 6 installed in the optical disc drive 11 to perform recording. or replay processing (S212).

In step S203, when the optical disc 6 is for playback only (S203: Yes), or in the case where the registration instruction of the optical disc 6 is not accepted in step S206 (S206: No), or in the step S208, the cancel registration instruction is not accepted. In this case (S208: No), the recording/reproduction control unit 24 starts accessing the optical disc 6 loaded in the optical disc drive 11 as an unregistered optical disc (S213). At this point, the video recording device 1 ends the processing for loading the optical disc 6 .

The video recording device 1 is operated by the remote controller 5 or the like, so that the video recording device 1 performs recording reservation processing. When the recording reservation process is started, the recording/playback control unit 24 causes the video display device 4 to display a recording reservation screen for accepting designation of a program to be recorded. FIG. 7 is a schematic diagram showing an example of a recording reservation screen. A video recording reservation screen is displayed by receiving a signal from the remote controller 5 on which the user performs a predetermined operation by the remote controller receiving unit 33 . In addition, when the recording reservation screen is displayed, the registered optical disc 6 may be mounted on the optical disc drive 11 or may not be mounted. In addition, a recording reservation screen may be displayed when the optical disc 6 is loaded.

A tab 71 is displayed on the recording reservation screen, and the tab 71 displays the type of the optical disc 6 registered on the registration screen of FIG. 4 . On the recording reservation screen, the same number of tabs 71 as the registered optical discs are displayed. On the label 71, the name for the user to grasp the registered optical disc is displayed. The name may be, for example, a registration number set on a login screen, or a name input by a user at the time of login. In FIG. 7 , it is shown that three optical discs are registered, and the names of "disc 1", "disc 2" and "disc 3" are respectively set.

In addition, each label 71 is displayed in the color registered for the optical disk corresponding to the displayed name. For example, when the disc color corresponding to "Disc 1" is set to "Green" on the login screen, the tab 71 indicating "Disc 1" is displayed in green. By displaying each label 71 in the color registered for the corresponding optical disk, the user can instantly grasp the type of the registered optical disk and which optical disk should be used.

On the recording reservation screen, a list display unit 72 for displaying reservation information in a list is displayed. The reservation information (program designation information) 73 of the optical disc corresponding to the selected tab 71 is displayed on the list display portion 72 . The reservation information 73 is information including the time, channel, program name, recording mode, etc. of the program to be recorded, and is displayed in correspondence with the color of the disc registered to the disc. Specifically, the list display unit 72 displays the colors registered for the optical disc 6 . Then, when the tab 71 of "Disc 1" is selected, the list display unit 72 displays it in the same color as the tab 71 corresponding to "Disc 1". Thus, the user can easily grasp which program is recorded on which disc. In addition, the reservation information 73 itself may be displayed using the registered disc color. For example, the frame indicating the reservation information 73 may be displayed in a registered color, or characters may be displayed in a registered color.

In addition, an electronic program table 74 is simultaneously displayed on the video recording reservation screen. On the electronic program guide 74, a plurality of program boxes (program columns) 74a, 74b indicating broadcast programs are displayed for each channel (hereinafter referred to as CH). Each program frame 74a, 74b is selectable, and the user selects the program frame 74a, 74b on the electronic program guide 74 by operating the remote control 5, thereby specifying the reserved program. At this time, the selected program frames 74a, 74b are displayed in the color registered for the optical disc corresponding to the selected tab 71 . For example, the program frame 74a is displayed in the same color as the label 71 corresponding to "disc 1". In addition, the program frame 74b is displayed in the same color as the label 71 corresponding to "Disc 3". By looking at the electronic program guide 74 in this way, the user can easily grasp which program is recorded on which optical disc. When recording is reserved, reservation information specifying the program for which recording is reserved is generated, associated with the media ID of the optical disc, and the reservation information is stored in the storage memory 27 and the optical disc, respectively. In addition, the generated reservation information is displayed on the list display unit 72 .

In addition, in FIG. 7, the list display part 72 etc. of the recording reservation screen are displayed using the color registered to an optical disc, but an icon image (identification information) may be registered when an optical disc is registered. FIG. 8 is a schematic diagram showing another example of the recording reservation screen. For example, on the login screen of FIG. 4 , it is possible to create an icon similar to the user's face, or to enable selection of a pre-registered image. Then, as shown in FIG. 8 , on the recording reservation screen, an icon image 75 registered to the disc is displayed superimposed on the tab 71 and the program frames 74 a, 74 b of the electronic program guide 74 . By displaying the icon image 75, it may be easier for the user to grasp the type of the optical disc than when the type of the optical disc is grasped only by the color. In addition, the registered icon image 75 has the same color as the above-mentioned optical disc, and is stored in the storage unit 12 and the optical disc 6, respectively.

Also can be, under the situation of displaying the video recording reservation screen of Fig. 7 or Fig. 8, if the optical disc 6 is installed in the optical disc drive 11, then in the state of selecting the tab 71 corresponding to the installed optical disc 6, start The recording reservation screen is displayed. In this case, since there is a high possibility that the user wishes to display information related to the mounted optical disc 6, troubles for the user can be saved.

FIG. 9 is a flowchart showing the procedure of recording reservation processing performed by the recording device 1 . The recording/playback control unit 24 acquires various information on the optical disc 6 loaded in the optical disc drive 11 (S31), and displays the recording reservation screen shown in FIG. 7 on the video display device 4 (S32). The acquired information is, for example, disc color information of the optical disc 6, generated reservation information, and the like. The recording/playback control unit 24 receives a signal from the remote controller 5 through the remote controller receiving unit 33, thereby accepting designation of a program to be recorded (S33). For example, the video display device 4 displays an electronic program guide 74 , and the user specifies a program on the electronic program guide 74 by operating the remote control 5 while confirming the electronic program guide 74 . Next, the recording/playback control unit 24 updates the display of the recording reservation screen according to the received program designation (S34).

The recording/playback control section 24 generates reservation information specifying a program reserved for recording, associates it with the media ID of the optical disc installed in the optical disk drive 11, and stores the reservation information in the memory 27 for preservation (S35 ). Next, the recording/playback control unit 24 causes the optical disc 6 loaded in the drive control unit 13 and the optical disc drive 11 to record reservation information (S36). At this point, the recording device 1 ends the recording reservation process.

In addition, in the flowchart of FIG. 9 , the information of the mounted optical disc 6 is obtained to display the video recording reservation screen, and the reservation information and the like are recorded on the optical disc 6 , but the optical disc 6 may not be mounted. In this case, in FIG. 7 or FIG. 8 , the user selects the tab 71 corresponding to the optical disc of the recording destination, and records the reservation information in the storage area of the corresponding storage unit 12 . Then, reservation information may be recorded on the optical disc 6 when the corresponding optical disc is mounted.

FIG. 10 is a conceptual diagram showing an example of the content of reservation information stored in the storage memory 27 . The media ID and reservation information are stored in association with each other. The reservation information includes information indicating channels and broadcast times of programs, and programs to be recorded are specified using these information. That is, the reservation information is information specifying a program in which program data is to be recorded, and corresponds to program specifying information in the present invention. In addition, the reservation information may be stored in association with the entry number of the storage area of the storage unit 12 corresponding to the optical disc, instead of being associated with the media ID. In this way, the storage memory 27 stores the reservation information in association with the registered optical disc.

FIG. 11 is a flowchart showing the procedure of recording processing performed by the recording device 1 . The recording/playback control unit 24 measures the time based on the clock, and constantly determines whether the broadcast time of the program indicated by the information included in the reservation information stored in the storage memory 27 has come (S41). When the broadcast time of the program has not yet come (S41: No), the recording/reproducing control unit 24 continues to measure the time. When the broadcast time of the program indicated by the information included in the reservation information has come (S41: YES), the recording/reproduction control unit 24 determines whether or not the optical disc 6 is loaded in the optical disc drive 11 (S42). When the optical disc 6 is installed in the optical disc drive 11 (S42: Yes), the recording/playback control unit 24 determines whether the optical disc 6 installed in the optical disc drive 11 is an optical disc associated with reservation information including information indicating broadcast time. (S43). In step S43, the recording/playback control unit 24 reads the medium ID from the optical disc 6, and based on whether the medium ID stored in the storage memory 27 in association with the reservation information matches the medium ID read from the optical disc 6, to judge.

In step S43, if the media IDs match and the optical disc 6 is an optical disc associated with reservation information (S43: Yes), the recording/reproduction control unit 24 performs the following process: The program data of the content of the program is recorded on the optical disc 6 (S44). In step S44, the digital tuner 21 converts the broadcast signal of the channel indicated by the reservation information into stream data, the stream processing unit 23 performs data processing on the stream data, and the recording/playback control unit 24 inputs the stream data from the interface unit 26. to the hybrid drive section 10. The stream data is program data that can reproduce the program by decoding, and represents the content of the program. Furthermore, in step S44, the recording/playback control unit 24 further performs a process of causing the drive control unit 13 to record the program data on the optical disc using the optical disc drive 11. For example, in the case where reservation information specifying a program whose broadcast time has come is associated with the optical disc 61 and the optical disc 61 is mounted in the optical disc drive 11 , program data is recorded on the optical disc 61 . In addition, the recording/playback control unit 24 may also perform the following processing: record the program data on the optical disc, and store the program data in the storage area of the storage unit 12 corresponding to the optical disc associated with the reservation information. middle.

When the broadcasting of the program ends and the recording of the program data ends, the recording/playback control unit 24 records title information on the optical disc 6. The title information indicates the title of the program represented by the program data recorded on the optical disc 6. (S46). As the title of the program, the title displayed on the electronic program guide 74, etc., can be used, such as the title determined based on the information contained in the broadcast signal received by the digital tuner 21, or the title set by the user's operation of the remote controller 5 can also be used. . Next, the recording/reproducing control unit 24 stores title information equivalent to the title information recorded on the optical disc 6 in the storage memory 27 (S47). In addition, the recording/playback control unit 24 may perform a process of storing the title information in the storage area corresponding to the optical disc 6 associated with the reservation information among the storage areas of the storage unit 12 .

In step S42, when the optical disc 6 is not installed in the optical disc drive 11 (S42: No), or in step S43, the media ID does not match, and the optical disc 6 is not a disc associated with the reservation information (S43: No), the recording The playback control unit 24 stores program data indicating the content of the program to be broadcast in the storage area corresponding to the optical disc associated with the reservation information among the storage areas of the storage unit 12 (S45). For example, the reservation information specifying the program whose broadcast time has come is associated with the optical disc 61, and it is determined whether the optical disc of the optical disc 61 is installed in the optical disc drive 11. , and store the program data in the first area of the storage unit 12 . When the broadcasting of the program ends and the recording of the program data ends, the recording/playback control unit 24 stores title information indicating the title of the program represented by the program data stored in the storage unit 12 in the storage memory 27 ( S47).

After step S47 ends, the recording/playback control unit 24 updates the mapping information representing the program data recorded on the optical disc 6 or the program stored in the storage unit 12 so as to reflect the processing up to step S47. The distribution state of the data (S48). Next, the recording/reproducing control unit 24 performs a process of deleting the reservation information of the program whose recording has been completed from the optical disk 6 and the storage memory 27 (S49), thereby ending the recording process.

12 and 13 are conceptual diagrams showing states of an optical disc on which program data is recorded or a storage unit 12 storing program data.

FIG. 12A shows a state in which the program data of program 1 is recorded in the first area of the storage unit 12 by step S45, and also shows that at least one of the recorded content of the optical disc 61 and the recorded content of the first area is recorded. A recording image of a virtual optical disc (virtual disc) on which program data is recorded. The program data of the program 1 is stored in the first area, and the program data is also recorded in the virtual disc accordingly. FIG. 12B shows an example of the contents of mapping information stored in the first area management unit of the storage unit 12 . The data distribution in the virtual disk and the first area is recorded in association with the data name of the program data using the head address and the data size. Furthermore, information indicating the synchronization state of the first area and the program data on the optical disc 61 is also recorded. Shown is the program data in which the head address of the program data is different but the same size is recorded in the virtual disc and the first area. In addition, since no program data is recorded on the optical disc 61, the synchronous state becomes asynchronous. In addition, in this embodiment, the address and data size of the memory are represented by decimal values. Fig. 12C shows an example of the contents of header information. In association with the title of the program represented by the program data, information indicating the duration of the program, the image quality, the number of possible dubbing times, and the synchronization state is recorded. In addition, the data name and the title name of the program data may be the same as shown in FIG. 12, or may be different from each other.

FIG. 13 shows a state where the program data of the program 1 is recorded on the optical disc 61 in step S44. As shown in FIG. 13A , the program data of program 1 is recorded on the optical disc 61 , and the program data is also recorded on the virtual disc accordingly. As shown in FIG. 13B , it is recorded in the mapping information that program data is recorded on the virtual disk, but no program data is stored in the first area. In addition, as shown in FIG. 13C, in the header information, regarding the program data recorded on the optical disc 61, the possible number of times of dubbing is not recorded.

After the recording device 1 starts accessing the registered optical disc 6 in step S212 , it performs a process of synchronizing the recorded content of the optical disc 6 with the stored content in the corresponding storage area of the storage unit 12 . FIG. 14 is a flowchart showing the procedure of synchronization processing performed by the recording device 1 . After starting to access the optical disc 6 in step S212, the recording/playback control unit 24 compares the recorded content of the optical disc 6 with the storage content in the storage area corresponding to the optical disc 6 in the storage area of the storage unit 12, and determines whether Whether unrecorded program data on the optical disc 6 is stored in the corresponding storage area (S51). In step S51 , for example, it is determined whether or not program data not recorded on the optical disc 61 is stored in the first storage area of the storage unit 12 . When unrecorded program data is stored (S51: YES), the recording/reproduction control unit 24 copies the unrecorded program data from the storage unit 12 to the optical disc 6 (S52). In step S52 , the recording/playback control unit 24 causes the drive control unit 13 to read unrecorded program data from the storage unit 12 , and records the read program data on the optical disc 6 using the optical disc drive 11 .

Next, the recording/playback control unit 24 updates the title information stored in the storage memory 27 (S53), and updates the mapping information stored in the management area of the storage unit 12 (S54) so that the information on the optical disc 6 is reflected. The status of program data is recorded. In step S54, for example, the mapping information stored in the first area management unit of the storage unit 12 is updated to reflect the state in which the program data is recorded on the optical disc 61 .

Next, the recording/playback control unit 24 judges whether reservation information related to program data recorded on the optical disc 6, that is, reservation information generated for recording a program indicated by the program data, is recorded on the optical disc (S55). In the case where the reservation information related to the program data recorded on the optical disk 6 is recorded in the optical disk (S55: Yes), the recording/playback control section 24 makes the drive control section 13 use the optical disk drive 11 to transfer the corresponding reservation information from the optical disk 6 Delete (S56).

In step S51, when there is no program data stored on the optical disc 6 (S51: No), or in step S55, when the reservation information related to the program data recorded on the optical disc 6 is not recorded on the optical disc ( S55: No), or after step S56 ends, the recording/reproducing control unit 24 determines whether reservation information not stored in the storage memory 27 is recorded on the optical disc 6 (S57). In the case where the reservation information not stored in the storage memory 27 is recorded on the optical disk 6 (S57: Yes), the recording/playback control section 24 copies the reservation information not stored from the optical disk 6 to the storage memory 27 (S58 ). In step S58, the recording/playback control unit 24 causes the drive control unit 13 to read the unstored reservation information from the optical disc 6 by using the optical disc drive 11, input the reservation information to the rear end unit 20 via the interface unit 14, and transfer the input The reserved reservation information is stored in the storage memory 27. In step S57, when unstored reservation information is not recorded on the optical disc 6 (S57: NO), or after step S58 ends, the recording/reproducing control unit 24 ends the synchronization process.

15 and 16 are conceptual diagrams showing the result of synchronizing the recording content of the optical disc with the storage content of the storage unit 12 .

FIG. 15 shows the synchronization result when the optical disc 61 on which no program data is recorded is loaded in the optical disc drive 11 in the state shown in FIG. 12 . As shown in FIG. 15A, on the optical disc 61, the same program data as that stored in the first area is recorded. The data distribution of the virtual disk is a data distribution reflecting the data distribution on the optical disk. In addition, as shown in FIG. 15B , the following situation is recorded in the mapping information: the program data of program 1 is stored in both the virtual disk and the first area, and regarding the program data of program 1, the recorded content of the optical disc 61 and the first area The stored content is synchronized. In addition, as shown in FIG. 15B , in the mapping information, the location of the program data representing the same program on the virtual disk, that is, the location on the optical disc, is associated with the location in the storage unit 12 . Therefore, program data representing the same program can be accessed both in the optical disc and in the storage unit 12 by referring to the mapping information. In addition, as shown in FIG. 15C , it is also recorded in the title information that the program data of the program 1 is synchronized with the first area on the optical disc 61 .

FIG. 16 shows a synchronization result when an optical disc 61 on which program data other than the program data stored in the first area of the storage unit 12 is recorded is loaded in the optical disc drive 11 in the state shown in FIG. 12 . In the state where the program data of program 1 is stored in the first area of the storage unit 12, when the optical disc 61 which has not recorded the program data of program 1 but recorded the program data of program 2 is installed in the optical disc drive 11, the program 1 The program data is added and recorded on the optical disc 61. As shown in FIG. 16A, program data of program 1 is recorded on the optical disc 61 in addition to the program data of program 2 already recorded. Therefore, the program data of the program 1 stored in the first area does not change, but the program data of the program 1 and the program 2 are recorded on the virtual disc. As shown in FIG. 16B, the following situation is recorded in the mapping information: both the virtual disk and the first area store the program data of program 1, and regarding the program data of program 1, the optical disc 61 is synchronized with the first area, and the first area No program data for program 2 is stored in . In addition, as shown in FIG. 16C , it is also recorded in the title information that the disc 61 is synchronized with the first area for the program 1, but it is not possible for the program 2 to be synchronized.

12, FIG. 13, FIG. 15 and FIG. 16, the program data is continuously recorded on the optical disc 61, but the video recording device 1 may also adopt a method capable of recording the program data in segments on the optical disc. In the recording device 1 of this type, program data is managed by associating the address of each part in which program data is recorded with the file name of the program data using FS (file system).

17 is a conceptual diagram showing the state of the optical disc on which the program data is recorded by the recording device 1 using the FS and the storage unit 12 storing the program data, showing that the program data of the program 1 stored in the first area is recorded on the optical disc 61. on status.

FIG. 17A shows a recording image of the virtual disc, the optical disc 61 and the recording contents of the first area. The program data of program 1 is stored in the first area, and the program data is divided into two parts, area 1 and area 2, on the optical disk 61 and recorded. In addition, FS data required for managing each file by FS is also recorded on the optical disc 61 .

The recording/playback control unit 24 needs FS data in order to access files. The storage memory 27 stores FS data equivalent to the FS data recorded on each optical disc in association with a medium ID. The recording/playback control unit 24 performs a process of synchronizing the FS data recorded on the optical disc with the FS data stored in the storage memory 27 when performing the synchronization process.

FIG. 17B shows an example of the content of the mapping information stored in the first area management unit of the storage unit 12 . Using the head address and the data size, data distributions of the virtual disk and the area 1 and area 2 in the first area are recorded. It is shown that on the virtual disc, the area 1 and the area 2 are dividedly recorded, and in the first area, the area 1 and the area 2 are continuously stored.

FIG. 17C shows an example of the content of the title information, which is the same as that of FIG. 15C and the like. FIG. 17D shows an example of the content of a part of FS data, showing the part related to the program data of program 1. FIG. In association with the data name of program 1, layout information is recorded. The layout information is composed of a head address and a size indicating the positions of area 1 and area 2 of the program data constituting program 1 on the virtual disc and the optical disc. By referring to the configuration information, program data recorded on the optical disc can be accessed.

In addition, the content of the configuration information is equivalent to the virtual disc map, and the program data stored in the storage unit 12 can be mapped by referring to the map in the storage area of the storage unit 12 that is associated with the virtual disc map contained in the configuration information using the map data. to access.

In addition, in the above description, for convenience of description, addresses and data sizes are shown in decimal numbers, but in fact, non-decimal numbers such as hexadecimal numbers are often used to manage addresses and data sizes.

The video recording device 1 can reproduce a program based on the program data recorded on the optical disc 6 after the synchronization process is completed. When the user performs a predetermined operation on the remote controller 5, the remote controller receiver 33 receives an instruction to start the program playback process, and the recording/playback control unit 24 causes the video display device 4 to display a program selection screen. A program to be reproduced is selected from programs represented by program data recorded on the optical disc 6 . FIG. 18 is a diagram schematically showing an example of a program selection screen.

On the program selection screen, like the tabs 71 of the recording reservation screen shown in FIG. 7 , the same number of tabs 81 as the registered optical discs 6 are displayed. Each tab 81 displays a name for the user to grasp the optical disc, and is selectable. In addition, a list display portion 82 for displaying title information 83 indicating reproducible programs is also displayed on the program selection screen. The title information 83 is recorded on the optical disc, and is displayed based on program data including the title of the recorded program, broadcast channel, recording time, recording mode, and the like. Title information 83 indicated by program data recorded on the optical disc 6 corresponding to the selected tab 81 is displayed on the list display portion 82 . At this time, on the list display portion 82, the title information 83 based on the program data recorded on the optical disc 6 corresponding to the selected tag 81 is displayed, and the list display portion 82 uses the The color registered on the disc is displayed. For example, when the tab 81 of "Disc 1" is selected, the list display unit 82 displays it in the same color as the tab 81 of "Disc 1". Thus, the user can easily grasp which optical disc is selected and which program is recorded on the optical disc. In addition, a video display unit 84 is also displayed on the recording selection screen. The video display unit 84 displays a program currently being broadcast or a program of program data stored in an optical disc. In addition, the title information 83 itself may be displayed using the registered disc color. For example, a registered color may be used to display the frame indicating the title information 83, and a registered color may be used to display characters.

Furthermore, on the recording selection screen, a list tab 85 displaying characters of "list" is displayed. FIG. 19 is a diagram schematically showing an example of a program selection screen when the list tab 85 is selected. When the list tab 85 is selected, the list display unit 82 displays title information 83 based on program data stored in all registered optical discs including unmounted optical discs. At this time, each piece of title information 83 is displayed in the color registered in the optical disc storing the program data. For example, the title information 83 based on the program data stored in the optical disc corresponding to "Disc 1" is displayed in the same color as the label 81 corresponding to "Disc 1". Thus, the user can easily grasp which program is recorded on which optical disc.

FIG. 20 is a flowchart showing the procedure of program playback processing performed by the recording device 1 . The recording/playback control unit 24 displays the program selection screen shown in FIG. 18 on the video display device 4 (S61). In step S61, the recording/playback control unit 24 extracts the title of the program represented by the program data recorded on the optical disc 6 mounted in the optical disc drive 11 from the title information stored in the storage memory 27, and displays A video signal required for the program selection screen including the extracted title is output from the signal output unit 34 to the video display device 4 . On the program selection screen, a list of programs indicated by the registered program data recorded on the optical disc, ie, reproducible programs, is displayed. In addition, the recording/playback control unit 24 may execute the process of step S61 immediately after finishing the synchronization process shown in the flowchart of FIG. 14 .

The user who has confirmed the program selection screen operates the remote controller 5, and receives a signal from the remote controller 5 by the remote controller receiver 33, so that the recording/playback control section 24 receives a request for a program to be played back from the user. choose. After step S61, the recording/playback control unit 24 waits for a program playback instruction to be received by accepting selection of a program to be played back (S62). When the program playback command has not been accepted (S62: No), the recording/playback control unit 24 continues to wait for the program playback command to be received. When the program playback instruction is accepted (S62: Yes), the recording/playback control unit 24 determines whether program data indicating a program to be played back is stored in the storage area corresponding to the optical disc 6 of the storage unit 12 (S62: Yes). S63). For example, when the program 1 indicated by the program data recorded on the optical disc 61 is to be reproduced, it is determined whether or not the program data of the program 1 is stored in the first area. In step S61, the recording/playback control section 24 refers to the title information, and if the synchronization status information associated with the title name of the program to be played back shows synchronization, it is determined that the program data is stored in the storage section 12, On the other hand, when synchronization is not shown, it is determined that program data is not stored. In addition, the recording/playback control unit 24 may perform a process of judging whether program data is stored in the storage unit 12 by referring to the mapping information stored in the management area of the storage unit 12 .

In the case where the program data indicating the program to be played back is stored in the storage area corresponding to the optical disk in the storage unit 12 (S63: Yes), the recording/playback control unit 24 performs the following processing: Stored program data to play back the program (S64). In step S64, the recording/playback control section 24 determines the address for storing the program data by referring to the mapping information stored in the management area of the storage section 12, and causes the drive control section 13 to read the program to be played back from the storage section 12. program data, and input the program data to the backend unit 20 via the interface unit 14.

In addition, the video recording device 1 collectively manages the program data recorded on the optical disc and the information of the program data stored in the storage area corresponding to the optical disc. The program data stored in the storage area is recorded on the optical disc, and when the program is reproduced, the program is reproduced based on the program data stored in the storage area. In this way, the recording device 1 uses each storage area of the storage unit 12 as a cache area that assists in reading program data from the optical disc and writing program data to the optical disc.

In addition, the recording device 1 records the program data stored in the storage area corresponding to the optical disc 6 on the optical disc 6 when the optical disc 6 is mounted. Thus, in the recording device 1, if the optical disc 6 is registered in advance and the reservation information is stored in association with the optical disc 6, the program data can be stored in the storage unit 12 even if the optical disc 6 is not installed when the program starts broadcasting. , and when the optical disc 6 is installed in the future, the program data is recorded on the optical disc 6. Therefore, even if the user forgets to install the optical disk in the video recording device 1 when the broadcast of the program starts, the program can be reliably recorded. In addition, even if the user installs another optical disc other than the specific optical disc on which the program data is to be recorded in the recording device 1 by mistake, the program data will not be recorded on the wrongly installed optical disc, but the program data will be recorded later. to the correct disc. Thus, in the present invention, program data can be reliably recorded at low cost without requiring a large-capacity hard disk or a plurality of tuners.

In addition, by storing the program data in the storage unit 12 , the recording device 1 can reproduce the program based on the program data stored in the storage unit 12 . Since the storage unit 12 composed of a nonvolatile memory or a hard disk reads data faster than an optical disc, the program can be played back more smoothly than when the program is played back based on the program data recorded on the optical disc. Can suppress the pressure on the user. Especially in the case of a video recording device that records program data on an optical disc and also stores the program data in the storage unit 12 when the program is broadcast, it is possible that the program data of the program to be played back is stored in the storage unit 12. The performance is high, and the program can be played back smoothly at a high frequency.
