Description

  The present invention relates to a recording apparatus that records content data such as program data representing the contents of a broadcast program on a recording medium such as an optical disk.

  Currently, recording devices (recording devices) that record programs broadcast by television broadcasting are in widespread use. The recording apparatus records program data representing the contents of program video or audio on a built-in recording medium such as a hard disk, and records program data on a portable recording medium such as a removable optical disk. There is. When recording is performed with a recording device that uses a built-in recording medium, the program can only be played back by the recording device that performed the recording, and the recording capacity is limited when program data is stored without being erased. Since there is a shortage, it is difficult to save program data. Therefore, in order to reproduce the program with another reproducing apparatus or to store the program data, the program data is dubbed from a built-in recording medium to a portable recording medium. However, the dubbing of the program data takes time, and it is difficult for the user who is unfamiliar with the operation of the electronic device to perform the dubbing. Patent Document 1 describes a recording apparatus that records a certain period of time using a hard disk and associates a program to be dubbed with an ID for identifying a portable recording medium. When a recording medium is loaded, the recording apparatus dubbs program data of a program associated with the ID of the recording medium among the programs recorded on the hard disk onto the recording medium. With this technique, once an operation for registering a program to be dubbed is performed, dubbing can be easily performed only by mounting a portable recording medium on the recording apparatus.

  A recording apparatus that performs recording by directly recording program data on a portable recording medium does not require dubbing. When a plurality of users use the same recording device at home, each user can hold his / her own recording medium, and each user can record a desired program on his / her own recording medium. In addition, when the user owns a plurality of recording devices, the recording can be performed on one recording medium using the plurality of recording devices. However, since recording reservation information is stored in the recording device when making a recording reservation, if a recording medium different from the recording medium used for recording is installed by mistake, the program is stored in the recording medium. Data will be recorded. Further, when using a plurality of recording devices, it is necessary to set a recording reservation in each recording device, which is troublesome. Patent Document 1 also describes a technique for recording recording reservation information on a portable recording medium and 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. Further, only by setting recording reservation with one recording apparatus, recording can be performed using the same recording medium even when another recording apparatus is used.

The optical disc is detachable from the optical disc drive 11 and corresponds to a recording medium in the present invention. The storage unit 12 is configured by a nonvolatile memory such as a flash memory or a hard disk.

  FIG. 3 is a schematic diagram showing the internal configuration of the storage unit 12. The storage unit 12 includes a management area for storing information for managing the storage contents of the storage unit 12, and a plurality of first areas, second areas,..., An nth area, and a spare area for storing program data. It is configured to include a storage area. Here, n is a positive integer. n is set to an appropriate value in advance, and when the recording apparatus 1 is shipped, the storage area of the storage unit 12 is divided in advance into a plurality of storage areas including a management area, first to nth areas, and a spare area. .

  Among the storage areas of the storage unit 12, the first to n-th areas are storage areas for associating specific optical disks individually and storing data corresponding to the associated optical disks. For example, a specific optical disk 61 is associated with the first area, and a specific optical disk 62 is associated with the second area. At the time of shipment of the recording apparatus 1, no optical disc is associated with any area. In order to use the recording apparatus 1, it is necessary to perform processing for registering the optical disk owned by the user in association with any storage area. The spare area is a storage area for storing other data.

  As shown in FIG. 3, the management area of the storage unit 12 includes a management area management unit that stores information for managing the management area, a first area, a second area,..., An nth area, and a spare area. Are configured to include a first area management unit, a second area management unit,..., An nth area management unit and a spare area management unit.

The media ID and the media key information are information recorded in advance on the optical disc, and are information specific to each optical disc. That is, the media ID and media key information correspond to the media information in the present invention. At the time of shipment of the recording apparatus 1, since the optical disc 61 is not yet associated with the first area, the allocation flag indicates that the optical disc is not associated. Media key information is not yet stored. The map information indicates to which address of the first area and the optical disc 61 the data stored in the first area and the data recorded on the optical disc 61 associated with the first area are distributed. Similar information is stored in each of the second to n-th area management units.

  Note that the recording apparatus 1 does not divide the storage area of the storage unit 12 in advance, but determines n by the user specifying the value of n, and stores the storage unit 12 according to the value of n. The form which performs the process which divides | segments an area | region may be sufficient. FIG. 4 is a flowchart illustrating a procedure of processing for dividing the storage area of the storage unit 12. The recording / playback control unit 24 causes the video display device 4 to display an acceptance screen for accepting designation of the number of optical disks that can be registered in the recording device 1, and a signal from the remote controller 5 on which the user has performed a predetermined operation is displayed on the remote controller. The reception unit 33 receives the designation of the number of optical disks that can be registered (S11). The recording / playback control unit 24 sets the number of entries by causing the management area management unit of the storage unit 12 to store the value of the designated number as the number of entries n (S12). Next, the recording / playback control unit 24 secures the first to nth region management units and the spare region management unit in the management region of the storage unit 12, and assigns allocation area information indicating the address of each allocated area. By storing in the management area management 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 unit 24 divides the storage area other than the management area of the storage unit 12 into (n + 1), and an allocation area indicating addresses of areas allocated to the first to nth areas and the spare area, respectively. The 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.

  Next, processing executed by the recording apparatus 1 having the above configuration will be described. FIG. 5 is a flowchart showing a procedure of processing performed by the recording apparatus 1 after the optical disc is loaded in the optical disc drive 11. When an optical disc is loaded into the optical disc drive 11 by a user operation, the drive control unit 13 reads the information recorded at a predetermined position in the optical disc by causing the optical disc drive 11 to read out the media ID of the optical disc. , Input from the interface unit 14 to the back-end unit 20. The recording / playback control unit 24 determines whether the read media ID is stored in any of the first to nth area management units of the storage unit 12, so that the mounted optical disk is an already registered optical disk. It is determined whether or not there is (S201). If the media ID is not stored in the storage unit 12 and the optical disc has not been registered (S201: NO), the recording / playback control unit 24 uses the optical disc drive 11 to read the optical disc from the optical disc. It is determined whether or not the optical disk is formatted (S202). In step S202, the determination is made based on, for example, a volume descriptor. If the optical disk is a formatted optical disk (S202: YES), the recording / playback control unit 24 determines whether the optical disk is a read-only optical disk based on the data read from the optical disk by the optical disk drive 11. (S203).

  If the optical disc is not read-only (S203: NO), the recording / playback control unit 24 determines whether an optical disc format instruction has been received (S204). For example, the recording / playback control unit 24 transmits a reception screen video signal for receiving an optical disc format instruction from the signal output unit 34 to the video display device 4 via the decoder 28 and the image processing unit 29. The video display device 4 displays a reception screen for receiving a format instruction. The user who confirms the reception screen inputs a format instruction by operating the remote controller 5 when formatting. When the remote control receiving unit 33 receives a predetermined signal transmitted from the remote controller 5 that has received a predetermined operation from the user and receives an optical disk format instruction (S204: YES), or the optical disk is formatted in step S202. If not completed (S202: NO), the recording / playback control unit 24 causes the drive control unit 13 and the optical disc drive 11 to format the optical disc (S205). If an optical disk format instruction is not received (S204: NO), the recording / playback control unit 24 determines whether an optical disk registration instruction is received (S206). For example, the recording / playback control unit 24 causes the video display device 4 to display an acceptance screen for accepting a registration instruction, and the remote control reception unit 33 accepts an instruction as to whether or not to register an optical disc. Note that the recording / playback control unit 24 may perform processing for causing the video display device 4 to display a reception screen that combines a reception screen for receiving a format instruction and a reception screen for receiving a registration instruction. Good.

  When step S205 is completed, or when an instruction to register an optical disc is received in step S206 (S206: YES), the recording / playback control unit 24 stores the storage unit based on the information stored in the management area of the storage unit 12. It is determined whether or not there is a storage area that is not associated with the optical disk in the 12th to nth areas (S207). If there is no storage area that is not associated with an optical disk (S207: NO), the recording / playback control unit 24 cancels registration of any one of the optical disks registered in association with each storage area. It is determined whether or not an instruction is received (S208). For example, the recording / playback control unit 24 displays on the video display device 4 a reception screen for receiving an instruction to cancel registration of an optical disk that has already been registered after notifying that new registration of the optical disk cannot be performed, and canceling registration. The remote control receiving unit 33 accepts an instruction as to whether or not to perform. Note that the recording / playback control unit 24 may perform a process of accepting an instruction as to which optical disk registration is to be canceled. When the registration cancellation instruction is received (S208: YES), the recording / playback control unit 24 deletes the medium information specific to one optical disk stored in the management area of the storage unit 12 in the drive control unit 13. By doing so, the process of canceling the registration of one optical disk is performed (S209). For example, when canceling the registration of the optical disc 61 associated with the first area of the storage unit 12, the recording / playback control unit 24 uses the media ID and the information stored in the first area management unit of the storage unit 12. Performs processing to erase media key information. At this time, the recording / playback control unit 24 rewrites the allocation flag stored in the first area management unit to a flag indicating that no optical disc is associated.

  If there is a storage area that is not associated with the optical disk in step S207 (S207: YES), or if step S209 is completed, the recording / playback control unit 24 uses the optical disk loaded in the optical disk drive 11 as the storage area. A process of registering in association is performed (S210). In step S210, the recording / playback control unit 24 stores the medium information specific to the optical disk loaded in the optical disk drive 11 in the management area of the storage unit 12 in association with the storage area not associated with the optical disk. Then, processing for registering the optical disk is performed. For example, when the optical disc 61 is associated with the first area of the storage unit 12, the recording / playback control unit 24 stores the media ID and media key information read from the optical disc 61 loaded in the optical disc drive 11 in the storage unit 12. Processing to be stored in one area management unit is performed. The recording / playback control unit 24 rewrites the allocation flag stored in the first storage management unit to a flag indicating that the optical disc is associated. If the media ID is stored in the storage unit 12 in step S201 and the optical disc has been registered (S201: YES), or if step S210 is completed, the recording / playback control unit 24 performs recording or playback, etc. In order to execute the above process, access to the optical disk loaded in the optical disk drive 11 is started (S211).

  If the optical disk is read-only in step S203 (S203: YES), if no optical disk registration instruction is accepted in step S206 (S206: NO), or if no registration cancellation instruction is accepted in step S208 (S208: NO), the recording / playback control unit 24 starts to access the optical disc loaded in the optical disc drive 11 as an unregistered optical disc (S212). The recording device 1 ends the process when the optical disc is loaded.

  The recording apparatus 1 performs a recording reservation process in a state where the registered optical disk is mounted on the optical disk drive 11. FIG. 6 is a flowchart showing a procedure of recording reservation processing performed by the recording apparatus 1. The recording / playback control unit 24 displays an acceptance screen for accepting designation of a program to be recorded on the video display device 4, and the remote control receiving unit 33 receives a signal from the remote controller 5 on which a user has performed a predetermined operation. By doing so, designation of a program to be recorded is accepted (S31). For example, the video display device 4 displays an electronic program guide, and the user operates the remote controller 5 while confirming the electronic program guide, whereby the program is designated on the electronic program. Next, the recording / playback control unit 24 generates reservation information for designating a program reserved for recording according to the designation of the received program, and associates the reservation information with the media ID of the optical disc loaded in the optical disc drive 11. Is stored in the storage memory 27 (S32). Next, the recording / playback control unit 24 causes the drive control unit 13 and the optical disc drive 11 to record reservation information on the optical disc loaded in the optical disc drive 11 (S33). The recording apparatus 1 ends the recording reservation process.

  FIG. 7 is a conceptual diagram showing an example of the contents of reservation information stored in the storage memory 27. The media ID and the reservation information are stored in association with each other. The reservation information includes information indicating the broadcast date and time of the channel and program, and the program to be recorded is designated by these information. That is, the reservation information is information for designating a program in which program data is to be recorded, and corresponds to program designation information in the present invention. 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 the media ID. In this way, the storage memory 27 stores the reservation information in association with the registered optical disc.

  FIG. 8 is a flowchart showing the procedure of the recording process performed by the recording apparatus 1. The recording / playback control unit 24 measures the date and time based on the clock and determines at any time whether or not the broadcast date and time of the program indicated by the information included in the reservation information stored in the storage memory 27 has come (S41). . If it is not the broadcast date / time of the program yet (S41: NO), the recording / playback control unit 24 continues to measure the date / time. When the broadcast date and time of the program indicated by the information included in the reservation information is reached (S41: YES), the recording / playback control unit 24 determines whether or not an optical disc is loaded in the optical disc drive 11 (S42). When an optical disk is loaded in the optical disk drive 11 (S42: YES), the recording / playback control unit 24 is associated with reservation information including information indicating the broadcast date and time when the optical disk loaded in the optical disk drive 11 is broadcast. It is determined whether or not (S43). In step S43, the recording / playback control unit 24 reads the media ID from the optical disc, and determines whether the media ID stored in the storage memory 27 in association with the reservation information matches the read media ID. Make a decision.

  In step S43, if the media IDs match and the optical disc is an optical disc associated with the reservation information (S43: YES), the recording / playback control unit 24 shows a program representing the content of the program for which broadcasting has started. A process of recording data on the optical disk by the optical disk drive 11 is performed (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 converts the stream data into the interface unit 26. To the hybrid drive unit 10. Stream data is program data that can reproduce a program by decoding and represents the contents of the program. Further, in step S44, the recording / playback control unit 24 performs a process of causing the drive control unit 13 to record program data on the optical disc by the optical disc drive 11. For example, when the reservation information for designating the program at the broadcast date and time is associated with the optical disc 61 and the optical disc 61 is loaded in the optical disc drive 11, the program data is recorded on the optical disc 61. Note that the recording / playback control unit 24 records the program data on the optical disk and stores the program data in the storage area corresponding to the optical disk associated with the reservation information in the storage area of the storage unit 12. May be.

  When the broadcast of the program ends and the recording of the program data ends, the recording / playback control unit 24 records title information indicating the title of the program represented by the program data recorded on the optical disc on the optical disc (S46). The title of the program may be a title determined based on information included in the broadcast signal received by the digital tuner 21 such as a title displayed on the electronic program guide, and the user operates the remote controller 5. The title set by may be used. Next, the recording / playback control unit 24 stores title information equivalent to the title information recorded on the optical disc in the storage memory 27 (S47). Note that the recording / playback control unit 24 may perform a process of storing the title information in a storage area corresponding to the optical disc associated with the reservation information within the storage area of the storage unit 12.

  If no optical disc is loaded in the optical disc drive 11 in step S42 (S42: NO), or if the media ID does not match in step S43 and the optical disc is not an optical disc associated with the reservation information (S43: NO) ), The recording / playback control unit 24 stores the program data representing the contents of the program for which broadcasting has started in the storage area of the storage unit 12 associated with the optical disc associated with the reservation information. (S45). For example, when the reservation information for specifying the program at the broadcast date / time is associated with the optical disc 61 and no optical disc is installed in the optical disc drive 11 or an optical disc other than the optical disc 61 is installed in the optical disc drive 11. The program data is stored in the first area of the storage unit 12. When the broadcast 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 is completed, the recording / playback control unit 24 reflects the processing up to step S47 with the map data indicating the distribution state of the program data recorded on the optical disc or the program data stored in the storage unit 12. Update (S48). Next, the recording / playback control unit 24 performs a process of deleting the reservation information of the program that has been recorded from the optical disk and the storage memory 27 (S49), and ends the recording process.

  FIG. 9A, FIG. 9B, FIG. 9C, FIG. 10A, FIG. 10B, and FIG. 10C are conceptual diagrams showing the state of the optical disk that records program data or the storage unit 12 that stores program data. FIG. 9A shows a state in which program data of program 1 is recorded in the first area of the storage unit 12 in step S45, and program data included in at least one of the recorded contents of the optical disc 61 and the recorded contents of the first area. The recording image of the virtual disk (virtual disk) which records is shown. Program data of program 1 is stored in the first area, and accordingly, program data is also recorded on the virtual disk. FIG. 9B shows an example of the contents of map information stored in the first area management unit of the storage unit 12. In association with the data name of the program data, the data distribution in the virtual disk and the first area is recorded by the head address and the data size. Furthermore, information indicating the synchronization state of program data between the first area and the disc 61 is recorded. It is shown that program data of the same size is recorded in the virtual disk and the first area, although the start addresses of the program data are different. Since the program data is not recorded on the optical disc 61, the synchronization state is not synchronized. In this embodiment, the memory address and the data size are represented by decimal numbers. FIG. 9C shows an example of the content of title information. In association with the title of the program represented by the program data, information indicating the length of time that the program continues, the image quality, the possible number of dubbing, and the synchronization state is recorded. The data name and title name of the program data may be the same as shown in FIGS. 9A, 9B, and 9C, but may be different from each other.

  10A, 10B, and 10C show a state in which the program data of program 1 is recorded on the optical disc 61 in step S44. As shown in FIG. 10A, the program data of the program 1 is recorded on the optical disc 61, and accordingly, the program data is also recorded on the virtual disc. As shown in FIG. 10B, in the map information, while program data is recorded on the virtual disk, it is recorded that no program data is stored in the first area. Further, as shown in FIG. 10C, the title information does not record the dubbable count for the program data recorded on the optical disc 61.

  After starting the access to the registered optical disk in step S211, the recording apparatus 1 performs a process of synchronizing the recorded contents of the optical disk with the stored contents in the corresponding storage area of the storage unit 12. FIG. 11 is a flowchart showing the procedure of the synchronization process performed by the recording apparatus 1. After starting access to the optical disk in step S211, the recording / playback control unit 24 compares the recorded content of the optical disk with the stored content in the storage area corresponding to the optical disk in the storage area of the storage unit 12. It is determined whether unrecorded program data is stored in the corresponding storage area (S51). In step S <b> 51, the recording / playback control unit 24 determines whether, for example, program data not recorded on the optical disc 61 is stored in the first storage area of the storage unit 12. If unrecorded program data is stored (S51: YES), the recording / playback control unit 24 copies the unrecorded program data from the storage unit 12 to the optical disc (S52). In step S 52, the recording / playback control unit 24 causes the drive control unit 13 to read unrecorded program data from the storage unit 12, and causes the optical disc drive 11 to record the read program data on the optical disc.

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

  Next, the recording / playback control unit 24 determines whether or not the reservation information related to the program data recorded on the optical disc, that is, the reservation information generated for recording the program represented by the program data is recorded on the optical disc. (S55). When the reservation information related to the program data recorded on the optical disc is recorded on the optical disc (S55: YES), the recording / playback control unit 24 sends the corresponding reservation information from the optical disc to the drive control unit 13 using the optical disc drive 11. Erasing is performed (S56).

  When unrecorded program data is not stored on the optical disc in step S51 (S51: NO), reservation information related to the program data recorded on the optical disc in step S55 is not recorded on the optical disc (S55: NO), or After step S56 is completed, the recording / playback control unit 24 determines whether reservation information that is not yet stored in the storage memory 27 is recorded on the optical disc (S57). If reservation information that is not yet stored in the storage memory 27 is recorded on the optical disk (S57: YES), the recording / playback control unit 24 copies the reservation information that is not stored from the optical disk to the storage memory 27 (S58). ). In step S58, the recording / playback control unit 24 causes the drive control unit 13 to read reservation information that is not yet stored from the optical disk by the optical disk drive 11, and inputs the reservation information to the back-end unit 20 via the interface unit 14. The inputted reservation information is stored in the storage memory 27. By the processing in steps S56 and S58, the reservation information recorded on the optical disc and the reservation information stored in the storage memory 27 match. If unstored reservation information is not recorded on the optical disc in step S57 (S57: NO), or after step S58 ends, the recording / playback control unit 24 ends the synchronization process.

  12A, 12B, 12C, 13A, 13B, and 13C are conceptual diagrams showing the results of synchronizing the recording content of the optical disc with the storage content of the storage unit 12. FIG. FIGS. 12A, 12B, and 12C show the synchronization results when the optical disk 61 that does not record program data is loaded in the optical disk drive 11 in the state shown in FIGS. 9A, 9B, and 9C. As shown in FIG. 12A, the same program data as the program data stored in the first area is recorded on the optical disc 61. The data distribution of the virtual disk is a data distribution reflecting the data distribution on the optical disk. Also, as shown in FIG. 12B, in the map information, the program data of program 1 is stored in both the virtual disk and the first area, and the recorded contents of the optical disk 61 and the stored contents of the first area are related to the program data of program 1. It is recorded that it is synchronized. As shown in FIG. 12B, in the map information, the location of the program data representing the same program on the virtual disk, that is, the location on the optical disc and the location on the storage unit 12 are associated with each other. Therefore, by referring to the map information, it is possible to access program data representing the same program on both the optical disc and the storage unit 12. As shown in FIG. 12C, the title information also records that the optical disc 61 and the first area are synchronized with respect to the program data of program 1.

  13A, 13B, and 13C show the optical disc 61 in which program data different from the program data stored in the first area of the storage unit 12 is recorded in the state shown in FIGS. 9A, 9B, and 9C. A synchronization result when the optical disc drive 11 is loaded is shown. The optical disc 61 in which the program data of the program 1 is not recorded and the program data of the program 2 is recorded is mounted in the optical disc drive 11 while the program data of the program 1 is stored in the first area of the storage unit 12. In this case, program data of program 1 is additionally recorded on the optical disc 61. As shown in FIG. 13A, program data of program 1 is recorded on optical disc 61 in addition to program data of program 2 already recorded. The program data of program 1 remains stored in the first area, and the program data of program 1 and program 2 are recorded on the virtual disk. As shown in FIG. 13B, in the map information, the program data of program 1 is stored in both the virtual disk and the first area, the optical disk 61 and the first area are synchronized with respect to the program data of program 1, and program 2 It is recorded that the program data is not stored in the first area. As shown in FIG. 13C, the title information also records that the program 1 is synchronized with the optical disc 61 and the first area, and the program 2 cannot be synchronized.

  9A, 9B, 9C, 10A, 10B, 10C, 12A, 12B, 12C, 13A, 13B, and 13C, the program data is continuously recorded on the optical disc 61. However, the recording apparatus 1 may be in a form capable of fragmenting program data and recording it on an optical disc. The recording apparatus 1 in this form manages program data by associating an address where each part of the program data is recorded with a file name of the program data using FS (file system). FIG. 14A, FIG. 14B, FIG. 14C, and FIG. 14D are conceptual diagrams showing the state of the optical disk on which the program data is recorded by the recording apparatus 1 using FS and the storage unit 12 that stores the program data. The state where the program data of the program 1 is recorded on the optical disc 61 is shown.

  FIG. 14A shows a recording image of the recording contents of the virtual disk, the optical disk 61, and the first area. Program data of program 1 is stored in the first area, and on the optical disc 61, the program data is divided and recorded in two parts, area 1 and area 2. In addition, FS data necessary for managing each file by FS is recorded on the optical disc 61. In order for the recording / playback control unit 24 to access the file, FS data is required. The storage memory 27 stores FS data equivalent to the FS data recorded on each optical disc in association with the media ID. The recording / playback control unit 24 performs a process of synchronizing the FS data recorded on the optical disc and the FS data stored in the storage memory 27 when performing the synchronization process.

  FIG. 14B shows an example of the contents of the map information stored in the first area management unit of the storage unit 12. The data distribution of the area 1 and the area 2 in the virtual disk and the first area is recorded by the head address and the data size. It is shown that area 1 and area 2 are divided and recorded on the virtual disk, and area 1 and area 2 are continuously stored in the first area. FIG. 14C shows a content example of title information, which is the same as FIG. 12C and the like. FIG. 14D shows an example of the contents of a part of the FS data, and shows a part related to the program data of the program 1. In association with the data name of the program 1, the arrangement information including the start address and the size indicating the location in the virtual disk and the optical disk in the area 1 and the area 2 constituting the program data of the program 1 is recorded. By referring to the arrangement information, it is possible to access the program data recorded on the optical disc. The contents of the placement information are equivalent to the virtual disk map, and are stored in the storage unit 12 by referring to the map in the storage area of the storage unit 12 associated with the virtual disk map included in the placement information by the map data. It is possible to access the programmed program data. In the above description, the address and data size are shown by decimal numbers for the sake of simplicity, but in reality, the address and data size are managed by numerical values other than decimal, such as hexadecimal numbers. There are many things.

  The recording apparatus 1 can reproduce the program based on the program data recorded on the optical disk after completing the synchronization process. FIG. 15 is a flowchart showing a procedure of program reproduction processing performed by the recording apparatus 1. When the user performs a predetermined operation on the remote controller 5, the remote controller receiver 33 receives an instruction to start program reproduction processing, and the recording / reproduction controller 24 selects a program represented by the program data recorded on the optical disc. A program selection screen for selecting a program to be reproduced is displayed 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 loaded in the optical disc drive 11 from the title information stored in the storage memory 27, and extracts it. A video signal necessary for displaying the program selection screen including the title is output from the signal output unit 34 to the video display device 4. The video display device 4 displays a program selection screen based on the video signal from the recording device 1. On the program selection screen, a list of programs represented by the program data recorded on the optical disc, that is, a list of reproducible programs is displayed. Note that the recording / playback control unit 24 may execute the processing of step S61 immediately after the synchronization processing shown in the flowchart of FIG.

  When the user who has confirmed the program selection screen operates the remote controller 5 and receives a signal from the remote controller 5 at the remote controller receiver 33, the recording / playback controller 24 selects the program to be played back from the user. Accept. After step S61, the recording / playback control unit 24 waits for reception of a program playback instruction by receiving selection of a program to be played back (S62). If there is no reception of a program playback instruction (S62: NO), the recording / playback control unit 24 continues to wait for reception of a program playback instruction. When an instruction for program playback is received (S62: YES), the recording / playback control unit 24 stores program data representing the program to be played back in the storage area associated with the optical disk in the storage unit 12. It is determined whether or not (S63). For example, when the program 1 represented by the program data recorded in 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 S63, the recording / playback control unit 24 refers to the title information, and the program data is stored in the storage unit 12 when the synchronization status information associated with the title name of the program to be played back indicates synchronization. It may be determined that the program data is not stored when the synchronization is not indicated. Note that the recording / playback control unit 24 may perform a process of determining whether program data is stored in the storage unit 12 by referring to the map information stored in the management area of the storage unit 12. .

  When program data representing a program to be reproduced is stored in the storage area associated with the optical disc in the storage area of the storage unit 12 (S63: YES), the recording / playback control unit 24 The program is reproduced based on the program data stored in the program 12 (S64). In step S64, the recording / playback control unit 24 identifies the address where the program data is stored by referring to the map information stored in the management area of the storage unit 12, and plays it back to the drive control unit 13. Program data representing a program to be read is read from the storage unit 12 and the program data is input to the back-end unit 20 via the interface unit 14. Further, the recording / playback control unit 24 causes the decoder 28 to decode the input program data into a video signal and an audio signal, causes the image processing unit 29 to perform image processing, and sends a video from the signal output unit 34 to the video display device 4. A signal and an audio signal are output. The video display device 4 reproduces a program by displaying video and outputting audio based on the video signal and audio signal from the recording device 1.

  When the program data representing the program to be played back is not stored in the storage area associated with the optical disc in the storage area of the storage unit 12 (S63: NO), the recording / playback control unit 24 uses the optical disc drive. 11 is performed on the basis of the program data recorded on the optical disk mounted on the optical disc 11 (S65). In step S65, the recording / playback control unit 24 causes the drive control unit 13 to read program data representing a program to be played back from the optical disc by the optical disc drive 11, and sends the program data to the back end unit 20 via the interface unit 14. To input. Further, the recording / playback control unit 24 causes the decoder 28 to decode the program data, causes the image processing unit 29 to perform image processing, and causes the signal output unit 34 to output a video signal and an audio signal. The video display device 4 reproduces a program based on the video signal and the audio signal from the recording device 1.

  As described above in detail, the recording apparatus 1 which is a recording apparatus according to the present invention is provided with the storage unit 12 having a plurality of storage areas separately from the optical disk drive 11, and is associated with a specific storage area and the medium ID of the optical disk. Is stored in association with a specific storage area. The recording apparatus 1 stores reservation information for recording in association with the optical disc, and records program data on the optical disc when the optical disc associated with the reservation information is loaded when the program to be recorded is broadcast. Is not loaded, program data is stored in a storage area corresponding to the optical disc. The recording apparatus 1 collectively manages information indicating program data to be recorded on the optical disc and program data to be stored in a storage area corresponding to the optical disc, and when the optical disc is loaded, the optical disc can be associated. 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. Thus, the recording apparatus 1 uses each storage area of the storage unit 12 as a cache area that assists reading and writing of program data to and from the optical disc.

  By using the storage unit 12, the recording apparatus 1 can temporarily store program data to be recorded on the optical disc in the storage unit 12 and then record the program data on the optical disc. Thus, once the recording apparatus 1 registers the optical disc and stores the reservation information in association with the optical disc, the recording device 1 stores the program data in the storage unit 12 even if the optical disc is not installed when the program starts broadcasting. The program data is recorded on the optical disk when the optical disk is loaded later. Therefore, the recording apparatus 1 can reliably record the program even when the user forgets to attach the optical disc to the recording apparatus 1 even when the program starts broadcasting. Further, even when the user mistakenly attaches an optical disc different from the specific optical disc on which the program data is to be recorded, the recording device 1 records the program data on the optical disc that is erroneously attached. However, program data will be recorded on the correct optical disk at a later date. As described above, the present invention enables reliable recording of program data at a low cost without requiring a large-capacity hard disk and a plurality of tuners.

  Further, 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. The storage unit 12 composed of a non-volatile memory or a hard disk reads data faster than an optical disk. Therefore, the recording apparatus 1 can reproduce a program more smoothly than when reproducing a program based on program data recorded on an optical disc, and can suppress stress applied to the user. In particular, a recording apparatus that stores program data in the storage unit 12 together with the recording of the program data on the optical disc during the broadcast of the program is highly likely that the program data of the program to be reproduced is stored in the storage unit 12. The program can be played smoothly at a high frequency.

  Further, in the present invention, when an unformatted optical disc is loaded, the recording device 1 performs processing for registering the optical disc after formatting the optical disc. As a result, the optical disc is registered only by mounting the unformatted optical disc on the recording apparatus 1, and the user can create and use the registered optical disc without troublesome work. In the present invention, the recording apparatus 1 can cancel the state in which the optical disk is registered by deleting the media ID of the optical disk stored in association with the storage area of the storage unit 12. As a result, the recording device 1 cancels the state in which the optical disk is associated with the storage area when the storage area that is not associated with the optical disk is insufficient in the storage area of the storage unit 12. A new optical disc can be associated. For example, when an optical disc on which program data is recorded is used for playback only, the recording apparatus 1 can cancel the registration of the playback-only optical disc and register another optical disc for recording.

  In the present invention, the recording apparatus 1 records the reservation information on the optical disc, and synchronizes the reservation information stored therein and the reservation information recorded on the optical disc when the optical disc is loaded. As a result, the recording device 1 can manage the reservation information and reliably record the program data even when the reservation information is recorded on the optical disc by another recording device.

  In the present embodiment, the medium ID pre-recorded on the optical disk is used as the medium information unique to the optical disk. However, the present invention is not limited to this, and the recording apparatus 1 is different for each optical disk. Information may be written on the optical disc, and the written information may be used as the media ID. In the present embodiment, the digital tuner 21 receives a broadcast signal. However, the recording apparatus 1 may include an analog tuner that receives an analog broadcast broadcast signal. In the form including an analog tuner, the analog tuner is connected to the encoder 22.

  In the present embodiment, the optical disk is used as the detachable recording medium in the present invention. However, the present invention is not limited to this, and the recording apparatus 1 may be a portable hard disk or a removable recording medium. The form using other recording media, such as a memory card, may be sufficient. In the present embodiment, the recording apparatus of the present invention is the recording apparatus 1. However, the recording apparatus of the present invention is not limited to this, and the video display apparatus 4 and the recording apparatus 1 are integrated. The form may be sufficient.

  In the present embodiment, the recording apparatus of the present invention has been described as recording the program data of a program broadcast by television broadcasting. However, the present invention is not limited to this, and the recording apparatus of the present invention is not limited to audio broadcasting. Or the form which records the program data of the program broadcast by broadcasts other than television broadcasts, such as data broadcast, may be sufficient. In the present embodiment, the content data in the present invention is program data. However, the present invention is not limited to this, and the content data is broadcast as arbitrary program data, video data, audio data, or the like. Data other than the program data of the program may be used. Therefore, the recording apparatus of the present invention may be configured to record content data other than the program data.
