The recorder device (100) according to the present invention is recorded on a disc loaded with reservation information recorded in the storage unit (280), and content specified by the reservation information is stored in the storage unit (340). If recorded, the content is recorded on a loaded disc, and a back-end control unit (240) for erasing reservation information designating the recorded content from the storage unit (280) is provided.

Description

  The present invention relates to a program recording apparatus for recording a program on a removable recording medium based on recording reservation information, and a program synchronization method in the program recording apparatus.

  Along with the spread of television receivers capable of high-definition display such as so-called full high-definition, a recorder apparatus capable of mounting a Blu-ray disc (BD) capable of recording large-capacity data such as full high-definition programs is also widely used. doing.

  Recorder devices that can be loaded with optical disks such as BDs include a type (hybrid recorder) with a built-in hard disk capable of recording data of a larger capacity than an optical disk, and a type without such a hard disk. (Straight recorder).

  Since the straight recorder records the recorded content (program) on the optical disc loaded in the recorder device, the recorder device can be operated by the same operation method as a conventional recorder device such as a video deck. However, when the optical disc is not loaded and when the data capacity of the loaded optical disc is insufficient, the content cannot be recorded, and content recording failures increase. In addition, since an optical disk having a data reading speed and writing speed inferior to those of a hard disk is used, the user is likely to feel stress in the operation response.

  In a hybrid recorder (for example, Patent Documents 1 and 2), recording and playback using a hard disk having a higher data reading speed and writing speed than an optical disk is possible, and the user is less likely to feel stress in an operation response. . That is, the hybrid recorder solves the problems of the straight recorder described above.

  However, users who are unfamiliar with hybrid recorders such as elderly people often cannot understand the operation method of the hybrid recorder because the concept that content (program) is recorded on a hard disk is difficult to understand. In addition, when content is played back on another device, processing for copying the content recorded on the hard disk to the optical disc occurs. In this case, since it is necessary for the user to select an optical disk on which the content is to be recorded and to be loaded into the recorder device, there is a problem that a mistake such as recording the content on the optical disk unintended by the user occurs. .

  In Patent Document 3, when a designated optical disk is not loaded, the content is recorded on the hard disk, and when the designated optical disk is loaded in the drive, the content recorded on the hard disk is recorded on the designated optical disk. A hybrid recorder device for dubbing is disclosed.

Japanese Patent Publication “JP 2007-234137 A (published on September 13, 2007)” Japanese Patent Publication “Japanese Patent Laid-Open No. 2005-50395 (published February 24, 2005)” Japanese Patent Gazette “Special Table 2007-517344 (June 28, 2007)” Japanese Patent Publication “JP 2001-356949 A (published on December 26, 2001)”

  According to the hybrid recorder apparatus described in Patent Document 3, it is possible to execute reserved recording regardless of whether or not a designated optical disk is loaded. However, if the designated optical disk is not loaded, processing other than the reserved recording cannot be executed on the designated optical disk.

  Further, in the hybrid recorder device described in Patent Document 3, the content recorded on the hard disk when the optical disk is not loaded is recorded on the optical disk when the designated optical disk is loaded. In this way, the process of synchronizing the data recorded between two devices usually compares the data recorded on one device with the data recorded on the other device, and calculates the difference. This is executed by recording in one device (see, for example, Patent Document 4). In other words, the hybrid recorder device described in Patent Document 3 compares the content recorded on the hard disk with the content recorded on the optical disk, so that the content recorded on the optical disk is recorded from the content recorded on the hard disk. By detecting the content that is not recorded and recording the detected content on the optical disc, the reserved recording content is recorded on the optical disc.

  However, when contents are compared with each other, there is a problem that it takes time to compare the contents. Further, when the content recorded on the optical disc is erased by another device, the content is recorded again.

  The present invention has been made in view of the above problems, and its main object is to record a program that shortens the time required to record a program recorded on a non-detachable recording medium on a removable recording medium. Is to provide a device.

  In this specification and the like, an optical disc associated with each area in the storage unit 340, that is, an optical disc in which the media ID of the storage unit 340 is recorded in the storage unit 340 is referred to as “my disc”.

  Each member with which the back end part 200 and the drive part 300 are provided is demonstrated below.

(Tuner unit 210, encoder unit 220)
The tuner unit 210 is a stream (Transport Stream: TS) in which video data, audio data, and the like are multiplexed from digital broadcast waves (for example, BS digital broadcast, CS digital broadcast, terrestrial digital broadcast) received by the antenna unit. To extract.

  The encoder unit 220 encodes the analog broadcast received by the antenna unit or the video / audio signal input from the outside into the MPEG2-TS format or the MPEG2-PS format.

(Stream processing unit 230, buffer unit 250)
The stream processing unit 230 separates and extracts individual data such as video data and audio data multiplexed in the extracted stream or the encoded stream, and a packet to which the same packet identifier (PID) is assigned. The content data (PES packet) is restored by connecting the payload portions of (TS). Further, content data input via a network by a communication unit (not shown) is also processed in the stream processing unit 230.

  The content data processed by the stream processing unit 230 is temporarily stored in the buffer unit 250. The buffer unit 250 is a memory that temporarily stores content data (video data, audio data, etc.) to be output to the display device or the drive unit 300. The buffer unit 250 generally uses a volatile memory, but may use a non-volatile memory.

(Backend control unit 240)
The back-end control unit 240 controls overall recording and reproduction of content data in the recorder device 100.

  When the content data restored in the stream processing unit 230 is recorded on the optical disc loaded in the drive unit 300, the back-end control unit 240 performs drive control via the interface unit 290 for a write command for writing to the optical disc. The content data to be written is read from the buffer unit 250 and output to the drive unit 300 via the interface unit 290.

  When playing back the content data recorded on the optical disk loaded in the drive unit 300, the back-end control unit 240 sends a read command for reading the content data from the optical disk to the drive unit 300, and the interface unit 290. To the drive control unit 320. At this time, the content data read from the optical disc is temporarily stored in the buffer unit 250.

  Further, when outputting the content data stored in the buffer unit 250 to the display device, the back-end control unit 240 controls the decoder unit 260 to decode the content data read from the buffer unit 250.

(Decoder unit 260)
In response to an instruction from the back-end control unit 240, the decoder unit 260 converts the content data stored in the buffer unit 250 into a clock (System Time Clock: STC) value generated in the back-end unit 200. Content data to which a matching time stamp (PTS) is assigned is read. Then, the read content data is decoded and output to the image processing unit 270.

(Image processing unit 270)

Details of the reservation information and the title management information will be described in detail below, and the description thereof is omitted here. Note that the storage unit 280 is preferably a non-volatile memory whose recorded contents are not erased even when the power is turned off.

(Interface units 290 and 310)
The interface unit 290 outputs the input data to the drive unit 300 via the interface unit 310. Examples of the interface unit 290 include SATA (Serial AT attachment). Note that ATA (AT attachment) is not limited to SATA whose transfer method is serial ATA, and PATA whose transfer method is parallel ATA may be used.

  The interface unit 310 outputs the input data to the backend unit 200 via the interface unit 290. The interface unit 310 can also be SATA (Serial AT attachment) or the like, like the interface unit 290, but the interface unit 290 and the interface unit 310 are preferably interfaces of the same standard.

  In the present embodiment, the case where the interface units 290 and 310 are SATA will be described as an example.

(Drive control unit 320)
The drive control unit 320 controls reading of data from the optical disc loaded in the disc drive unit 330 and writing of data to the optical disc, reading of data from the storage unit 340, and data to the storage unit 340. Control writing.

  In the drive control unit 320, a command (a data read command from the optical disc or a data write command to the optical disc) input from the back end control unit 240 that is input via the interface unit 310, a data read command from the storage unit 340, Alternatively, it is replaced with a data write command to the storage unit 340. However, when the command from the back end control unit 240 is a read command for data not stored in the storage unit 340, the drive control unit 320 does not replace the command from the back end control unit 240 and loads Read data from the optical disc.

  When the interface units 290 and 310 are ATA interfaces, a write command and a read command from the back-end control unit 240 are ATA commands.

It is preferable to include the command and output it to the drive control unit 320. Of course, in addition to using a command including disk designation information, a command indicating the disk designation information is output in advance to designate a recording target area (my disk) in the storage unit 340, and then a write command and write target data are represented. The command may be output to the drive control unit 320. In any case, the write command includes disk designation information and an address (first area designation information) that designates an area in which data is to be written. Note that the data to be written is output from the back end unit 200 to the drive unit 300 together with the write command.

  This is not limited to the write command, and the same applies to the read command.

(Disc drive unit 330)
The disk drive unit 330 operates based on an instruction from the drive control unit 320, and reads data from the loaded optical disk or writes data to the optical disk.

  The disk drive unit 330 includes an optical pickup unit for reading data from a loaded optical disk and writing data to the optical disk.

(Storage unit 340)
The storage unit 340 is a data memory that stores data such as content data to be recorded on the optical disc in the recorder device 100. The recording of content data in the storage unit 340 will be described in detail below, and the description thereof is omitted here.

  The storage unit 340 is not particularly limited as long as the data access speed is higher than that of the optical disc, but is preferably a nonvolatile memory in which recorded contents are not erased even when the power is turned off. More specifically, it is preferable to use a flash memory.

(Processing operation of recorder device 100)
Next, the playback operation, recording operation, dubbing operation, and the like of the recorder device 100 will be described. Prior to the description of each operation in the recorder device 100, the presetting in the recorder device 100 will be described with reference to FIG. This will be described with reference to (b) and (a) and (b) of FIG. The presetting in the recorder apparatus 100 can be roughly divided into two processes: an initialization process for the storage unit 340 and an optical disk registration process for the storage unit 340.

<Initialization Processing of Storage Unit 340>
The initialization process of the storage unit 340 will be described with reference to (a) and (b) of FIG. 2A and 2B are diagrams illustrating an initialization process of the storage unit 340. FIG. 2A is a diagram illustrating an example of display on the display device when the storage unit 340 is initialized. (B) is a diagram schematically showing the storage unit 340 after the initialization process.

  The initialization process of the storage unit 340 is a process of virtually dividing the storage area in the storage unit 340 into as many partitions as the user desires. Note that the initialization processing of the storage unit 340 is executed only when the storage area is not virtually divided in the storage unit 340, and therefore the initialization processing in the storage unit 340 has already been performed. The initialization process is not executed for.

  The initialization process is executed by receiving an initialization process execution instruction from the user via the operation input unit. That is, when the back-end control unit 240 receives an initialization processing execution instruction from the user, the back-end control unit 240 virtually determines the storage area of the storage unit 340 to the number designated by the user with respect to the drive control unit 320. Instruct to split. In response to the instruction from the back-end control unit 240, the drive control unit 320 virtually divides the storage unit 340 into a specified number of areas (partitions). The number of areas divided in the storage unit 340 matches the number of My Disks that can be registered. At this time, it is preferable to display an image as shown in FIG.

  Note that the number of regions virtually divided in the storage unit 340 may be a number explicitly designated by the user, such as “n (sheets)”, or may be a recording desired by the user. The number may be set according to the image quality.

  FIG. 2B shows the storage unit 340 after the initialization process. As shown in FIG. 2B, the storage unit 340 is virtually divided into n regions (region 1 to region n) desired by the user. In addition to the areas 1 to n, the storage unit 340 is provided with a management area in which management information for managing the areas 1 to n is recorded.

  As shown in FIG. 2B, the management area can be divided into a my disk management area for managing the areas 1 to n and a memory management area for managing the my disk management area.

  In the my disk management area, management information for managing the areas 1 to n is recorded. In FIG. 2B, for convenience, an area in which management information for managing area 1 is recorded is referred to as “entry 1”, and an area in which management information for managing areas 2 to n is similarly recorded. Called entries 2-n.

  In entry 1 managing area 1, an entry number, an allocation flag, media ID information, allocation area information, media key information, and map information are recorded. Each of these pieces of information will be described below.

  “Entry number” is information indicating which area is to be managed. For example, since entry 1 is management information for managing area 1, information indicating “1” is recorded as the entry number.

  The “assignment flag” is a flag indicating whether or not the area is associated with MyDisk. In the state immediately after the initialization process, since my disk is not associated, information indicating that the assignment is not performed (here, “0”) is recorded.

  “Media ID” is information indicating the media ID of the optical disc. In the initialization process stage, the media ID information is not recorded. The recording of the media ID information will be described later in the optical disk registration process.

  The “allocation area information” is information indicating a recording area of the storage unit 340 that can be used as each area. As specific examples of the allocation area information, for example, the start address and the end address of each area can be cited. Further, the recording capacity of each area may be recorded instead of the end address.

  “Media key information” is key information for executing encryption used for copyright protection when data is recorded on an optical disc. Examples of the media key information include MKB (Media Key Block).

  “Map information” includes, for each content recorded on the optical disc, a virtual address that is an address indicating an area of the optical disc in which the content is recorded, and an address that indicates an area on the storage unit 340 in which the content is recorded. This is information indicating the association with the physical address. The details of the map table recorded as the map information will be described in detail below, and the description is omitted here.

  Further, as shown in FIG. 2B, “entry number information” and “allocation area information” are recorded in the memory management area. “Number of entries” is information indicating the number of regions virtually divided in the storage unit 340. “Allocation area information” is information indicating an area used as a My Disk management area in the storage unit 340.

  Note that a surplus area generated when the storage unit 340 is virtually divided into the areas 1 to n may be used as a spare area.

<Optical disk registration process>
Next, an optical disk registration process with respect to the storage unit 340 will be described with reference to FIGS. 3A and 3B are diagrams showing an optical disk registration process, FIG. 3A is a diagram showing an example of display on the display device during the optical disk registration process, and FIG. It is the figure which showed typically the memory | storage part 340 after the registration process of an optical disk.

  The optical disk registration process is a process of recording the media ID of the optical disk for the entry managing each area virtually divided in the storage unit 340.

  When the optical disk is loaded in the drive unit 300, the drive control unit 320 instructs the disk drive unit 330 to read the media ID of the optical disk from the loaded optical disk. When the disk drive unit 330 reads the media ID from the optical disk, the drive control unit 320 determines whether the media ID read in the storage unit 340 is a media ID already recorded in an entry in the my disk management area. .

  When the read media ID is not recorded in any of the entries in the my disk management area, the drive control unit 320 indicates that the allocation flag is not allocated to the optical disk among the entries in the my disk management area. The read media ID is recorded in the entry “0”. Thereby, the media ID information is recorded in the entry. Note that the allocation flag in the entry in which the media ID information is recorded is changed to “1” indicating that the allocation is performed at the time when the media ID information is recorded. Also, information unique to the optical disc such as media key information is also recorded for the entry that recorded the media ID information at this time.

  In the above-described optical disk registration process, the case where the read media ID is automatically recorded in the entry whose assignment flag is “0” has been described. It is preferable to ask the user whether or not to record in the entry. In this case, the drive control unit 320 records the media ID in response to an instruction from the user that the recorder device 100 records the media ID in the entry.

  In addition, when there are a plurality of entries having an allocation flag “0”, the user may be able to select which entry the media ID is recorded on. In this case, the drive control unit 320 records the media ID for the entry specified by the user.

  When recording the media ID in the entry, it is preferable to display an image as shown in FIG. 3A on the display device.

  FIG. 3B shows the state of the storage unit 340 after registration of the optical disc when the optical disc having the media ID “aaa” is recorded in the entry 1.

  When the media ID of the optical disk is recorded in entry 1, the optical disk is associated with area 1 managed by entry 1, as shown in FIG.

  In this specification and the like, an optical disc associated with each area in the storage unit 340, that is, an optical disc in which the media ID of the storage unit 340 is recorded in the storage unit 340 is referred to as “my disc”. In addition, in order to identify the My Disk, here, the My Disk associated with the area 1 is referred to as “Disk 1”. Similarly, the my disk associated with the areas 2 to n will be referred to as “disks 2 to n”.

<Reserved video recording operation>
The following describes the content recording operation, content playback operation, content editing operation, and content copy operation in the recorder apparatus 100 for which the above-described preset settings have been completed.

  The content recording operation in the recorder apparatus 100 will be described below with reference to FIGS. 4 (a) to (c) to FIG. 13 (a) to (c). Here, the reservation recording process will be described as an example of the content recording operation.

  The reserved recording process in the recorder apparatus 100 can be roughly divided into a reservation registration process and a recording process. The recording process can be further divided into two processes: a recording process in a state where a my disk is loaded and a recording process in a state where a my disk is not loaded. Each of these processes in the scheduled recording process will be described below.

(Reservation registration process)
First, reservation registration processing in the recorder device 100 will be described below with reference to FIGS. 4A to 4C are diagrams illustrating reservation registration processing in the recorder device 100, and FIG. 4A is a diagram schematically illustrating the state of the storage unit 280 after the reservation registration processing. FIG. 6B is a diagram schematically showing the state of the storage unit 340 and the MyDisk 1 after the reservation registration process, and FIG. 5C is a diagram showing an example of display on the display device during the reservation registration process.

  The reservation registration process is a process for registering reservation information in the storage unit 280 and the optical disc. The reservation registration process will be described by taking as an example a case where the disk 1 associated with the area 1 of the storage unit 340 is loaded.

  When the user inputs reservation information via the operation input unit, the back-end control unit 240 records the input reservation information in the reservation information management area of the storage unit 280. At this time, the reservation information recorded in the reservation information management area of the storage unit 280 includes “recording channel”, “recording date” and “recording time” as well as “recording time” as shown in FIG. Information on “Target My Disk” is included. Hereinafter, the medium ID of the loaded MyDisk will be described as an example of the recording target MyDisk information. However, other information may be used as long as the information can identify the MyDisk. Each piece of information included in the reservation information may be input by the user, or may be set based on program information representing a program selected by the user in the electronic program guide.

  The back-end control unit 240 records the reservation information in the storage unit 280 and instructs the drive control unit 320 to write the reservation information to the disk 1 loaded in the drive unit 300. In response to the instruction from the back-end control unit 240, the drive control unit 320 instructs the disk drive unit 330 to record the reservation information set by the user on the disk 1. In response to an instruction from the drive control unit 320, the disk drive unit 330 records the reservation information set by the user in a predetermined area (reservation information management area) of the disk 1 ((b) of FIG. 4). At this time, since the media ID is already recorded on the disc 1, it is not necessary to record the media ID.

  It should be noted that the user may be able to select the recording target my disk when setting the reservation information. In this case, if the recording target my disk selected by the user is not loaded in the drive unit 300, the user is warned to load the target my disk in the drive unit 300 at the time of registration of the reservation information. It is preferable to do so.

  FIG. 4C shows an example of an image displayed on the display device at the time of reservation registration when the disc 1 associated with the area 1 of the storage unit 340 is loaded.

  As described above, in the reservation registration process in the recorder device 100, the reservation information is recorded in the storage unit 280 in the back-end unit 200 and also in the loaded My Disk. In other words, a reservation information recording area for recording reservation information on the My Disk is also provided.

(Registering reservation information from MyDisk)
As described above, the recorder device 100 can perform reservation registration by acquiring reservation information recorded on the My Disk in another device, in addition to performing reservation registration in the own device as described above.

  When reservation information that is not recorded in the storage unit 280 of the recorder device 100 is recorded in the reservation information recorded on the loaded My Disc, the recorder device 100 reads the reservation information from the My Disc. And recorded in the reservation information management area of the storage unit 280. Thus, even when the reservation registration process is performed in another device, the reservation information recorded on the My Disk and the reservation information recorded on the recorder device 100 always coincide.

(Recording process when My Disk is loaded)
Next, with respect to the recording process in the case where a My Disk having the media ID included in the reservation information recorded in the reservation information management area of the storage unit 280 is loaded in the drive unit 300, (a) in FIG. This will be described below with reference to (b). (A) and (b) of FIG. 5 are diagrams showing a recording process in a state where the My Disc is loaded, and (a) schematically shows the states of the storage unit 340 and the My Disc 1 after the recording process. (B) is a diagram schematically showing the state of the storage unit 280 after the recording process.

  When the recording of the content 1 is completed, the back-end control unit 240 deletes the reservation information indicating the reserved recording of the content 1 from the reservation information management area in the storage unit 280 as shown in FIG. To do. When the recording of the content 1 on the disc 1 is completed, the drive control unit 320 instructs the disc drive unit 330 to erase the reservation information recorded in the reservation information management area of the disc 1.

  Next, the state of the storage unit 340 and the storage unit 280 when the content 1 is recorded in the area 1 of the storage unit 340 and the disc 1 will be described below with reference to FIGS. 6A to 6C are diagrams showing the states of the storage unit 340 and the storage unit 280 when the content 1 is recorded. FIG. 6A shows the recording state of the content in the area 1 of the storage unit 340. It is a figure which shows the corresponding relationship of the recording state of the corresponding disc 1, (b) is a figure which shows the map table at the time of recording the content 1, (c) is a title management table at the time of recording the content 1 FIG.

  Here, generally, the data capacities of the area 1 of the storage unit 340 and the disk 1 are different. Therefore, in the area 1, a virtual address that matches the address (first area designation information) in the disk 1 is assigned separately from the physical address. By reading or writing data using this virtual address, the content stored in the storage unit 340 is recorded on the disc 1 loaded in the drive unit 300 in the back-end unit 200. Can be handled. In this specification and the like, a storage area represented by using a virtual address set in each area of the storage unit 340 is referred to as a “virtual disk image”.

  FIG. 6A shows a virtual disk image in the area 1 of the storage unit 340. As shown in FIG. 6A, in the area 1 of the storage unit 340, content 1 (data capacity: XGB) is recorded with the physical address (second area designation information) “0x000” as the head address. On the virtual disk image, the content 1 is recorded with the virtual address “0x050” as the head address. That is, when the content 1 is written to the disc 1, the drive control unit 320 instructs the disc drive unit 330 to write the content 1 from the sector representing the address “0x050” of the disc 1. As a result, content recording from the area 1 to the disc 1 can be easily executed.

  Next, a map table for realizing the association between the physical address and the virtual address shown in FIG. 6A will be described with reference to FIG.

  The map table is recorded as map information in the My Disk management area of the storage unit 340. As shown in FIG. 6B, the map table records a virtual disk map representing a map in the virtual disk image and a memory map representing a map in the area 1 of the storage unit 340 in association with each content. ing. Further, a synchronization flag indicating whether or not the content is recorded on the My Disc is recorded in association with the content.

  In this specification and the like, a state where content recorded in a certain area of the storage unit 340 is recorded on a My Disk associated with the certain area is referred to as “synchronization”. Similarly, a process in which content recorded in a certain area of the storage unit 340 is recorded on a My Disk associated with the certain area is referred to as “synchronization process”.

  In the map table, content 1 is recorded in area 1 and the content is updated. FIG. 6B shows a map table when the area 1 of the storage unit 340 is in the state shown in FIG. As shown in FIG. 6B, in the map table, “0x050” is set as the head address in the virtual disk map in content 1, XGB is set as the data size, and “0x000” is set as the head address in the memory map. Is set, and XGB is set as the data size. Further, the writing from the area 1 to the disc 1 is completed, and the synchronization flag in the map table becomes “1” indicating that the content is recorded on the My Disc.

  By referring to such a map table, the drive control unit 320 that has received a write command to the disk 1 from the back-end control unit 240 sends the write command to the disk 1 received from the back-end control unit 240 to the area 1. Can be changed to a write command. Similarly, a read command from the disk 1 can be changed to a read command from the area 1 by referring to the map table.

  The entry parameter in FIG. 6B is an area for recording an entry number, media ID information, allocation area information, and the like, and the entry data area is for recording media key information and track information in area 1. It is an area to do.

  Further, the content 1 is recorded in the area 1, and the title management table recorded as the title management information in the title management area of the disc 1 in the storage unit 280 is updated. The title management table recorded in the content management area in which information related to the content 1 is set will be described with reference to FIG. Note that as many title management areas as the number of areas virtually divided in the storage unit 340 are provided in the storage unit 280.

  In the title management table, as shown in FIG. 6C, for the title name indicating each content, the required time for content reproduction, the image quality of the content reproduction, and the number of remaining dubbing times (maximum 10). In addition, information indicating the synchronization state is recorded in association with each other. Note that a title indicating the content 1 is described as a title 1. Similarly, titles indicating content 2 to content n are written as title 2 to title n.

  An example of the title management table when the map table shown in FIG. 6B is set is shown in FIG. At this time, since the content 1 is recorded on the disc 1, the remaining dubbing count in the title 1 is subtracted once from the remaining 10 times to “9” times.

(Recording process when My Disk is not loaded)
Next, with respect to the recording process when the My Disk having the media ID included in the reservation information recorded in the reservation information management area of the storage unit 280 is not loaded in the drive unit 300, (a) in FIG. This will be described below with reference to (b). (A) and (b) of FIG. 7 are diagrams showing a recording process in a state where the my disk is not loaded in the recorder apparatus 100, and (a) schematically shows the state of the storage unit 340 after the recording process. (B) is a diagram schematically showing the state of the storage unit 280 after the recording process.

  In the recorder apparatus 100, when the recording of the content (content 2) recorded by the reservation information recorded in the reservation information management area of the storage unit 280 is started, the disc 1 is not loaded in the drive unit 300. Even so, the back-end control unit 240 instructs the drive control unit 320 to record the content 2 on the disc 1. The drive control unit 320 that has received an instruction from the back-end control unit 240 receives a write command from the back-end unit 200 to the disk 1 in the area 1 of the storage unit 340 because the disk 1 is not loaded in the disk drive unit 330. The content 2 is recorded in the area 1. At this time, since the disc 1 is not loaded in the drive unit 300, the process of recording the content 2 on the disc 1 is not executed.

  Here, as shown in FIG. 7B, in the recorder device 100, unlike the case where the My Disk is loaded, the back-end control unit 240 reserves the reservation in the storage unit 280 even when the recording of the content 2 is completed. The reservation information indicating the reserved recording of the content 2 is not deleted from the information management area.

  Next, the state of the storage unit 340 and the storage unit 280 when the content 2 is recorded in the area 1 of the storage unit 340 will be described below with reference to FIGS. 8A to 8C are diagrams showing the states of the storage unit 340 and the storage unit 280 when the content 2 is recorded, and FIG. 8A shows the recording state of the content in the area 1 of the storage unit 340. It is a figure which shows the corresponding relationship of the recording state of the corresponding disc 1, (b) is a figure which shows the map table at the time of recording the content 2, (c) is a title management table at the time of recording the content 2 FIG.

  As shown in FIG. 8A, since content 1 (data capacity: XGB) is recorded with the physical address “0x000” in the area 1 of the storage unit 340 as the head address, content 2 (data capacity: XGB) is recorded. Is recorded following the content 1 with the physical address “0x200” in the area 1 of the storage unit 340 as the head address. At this time, the content 2 is recorded following the content 1 with the virtual address “0x250” as the head address even on the virtual disk image. Since the disc 1 is not loaded in the drive unit 300, the content 2 is naturally not recorded on the disc 1.

  The content 2 is recorded in the area 1, and the map table recorded in the map information in the entry 1 of the storage unit 340 is also updated. FIG. 8B shows a map table in which the area 1 of the storage unit 340 is in the state shown in FIG. As shown in FIG. 8B, in addition to the map table shown in FIG. 6B, “0x250” is set as the start address in the virtual disk map in content 2, and XGB is set as the data size. “0x200” is set as the head address in the memory map, and XGB is set as the data size. At this time, since writing from the area 1 to the disc 1 is not executed, the synchronization flag of the content 2 in the map table is “0” indicating that the content is not recorded on the My Disc.

  FIG. 8C shows an example of the title management table when the map table shown in FIG. 8B is set. As shown in FIG. 8C, in the title management table, in addition to the title management information of the title 1 indicating the content 1 shown in FIG. 6C, the title management information of the title 2 indicating the content 2 is stored. Added. Since the title 2 is not recorded on the disc 1 at this time, the remaining dubbing count in the title 2 remains “10”, and the synchronization state is information indicating unsynchronization.

(Content synchronization processing)
Next, with regard to the synchronization processing for recording content recorded in the storage unit 340 but not recorded on the My Disc on the My Disc, (a) to (c) of FIGS. Will be described below.

  When the disc 1 is loaded in the drive unit 300, the back-end control unit 240 records in the storage unit 340 content to be synchronized with the disc 1 (content to be synchronized; content 2 in FIG. 9). Determine whether or not. The details of the method for determining the synchronization target content is the greatest feature of the present invention, and will be described in detail with reference to the drawings referred to below.

  When it is determined that the synchronization target content exists, the back-end control unit 240 instructs the drive control unit 320 to read the synchronization target content. The drive control unit 320 reads the synchronization target content from the storage unit 340 and outputs it to the back-end unit 200. The back-end control unit 240 instructs the drive control unit 320 to record (write out) the read synchronization target content on the disc 1.

  Upon receiving the instruction, the drive control unit 320 instructs the disc drive unit 330 to record the synchronization target content output from the back-end unit 200 on the disc 1.

  The disc drive unit 330 records synchronization target content on the disc 1. As a result, the contents (contents 1 and 2) recorded in the area 1 of the storage unit 340 are both recorded on the disc 1 (FIG. 9).

  When the recording of the synchronization target content on the disc 1 is completed, the drive control unit 320 notifies the back end unit 200 that the synchronization target content recording process has been completed. Upon receiving this notification, the back end control unit 240 updates the title management table recorded in the title management area of the disc 1 in the storage unit 280. Further, the back-end control unit 240 deletes the reservation information of the synchronization target content recorded in the reservation information management area of the storage unit 280 (FIG. 9).

  In addition, when the recording of the synchronization target content on the disc 1 is completed, the drive control unit 320 instructs the disc drive unit 330 to delete the reservation information for pre-recording the synchronization target content recorded on the disc 1. To do. Upon receiving the instruction, the disk drive unit 330 deletes reservation information for reservation recording of the content 2 recorded in the reservation information management area of the disk 1 (FIG. 9). FIG. 9 is a diagram illustrating the states of the storage unit 340, the storage unit 280, and the disc 1 after the content synchronization processing.

  Next, with respect to the state of the storage unit 340 and the storage unit 280 when the content 2 (synchronization target content) recorded in the area 1 of the storage unit 340 is synchronized with the disc 1, (a) to (c) of FIG. The following will be described with reference to FIG. 10A to 10C are diagrams showing the states of the storage unit 340 and the storage unit 280 when the content 2 is synchronously processed. FIG. 10A is a recording state of the content in the area 1 of the storage unit 340. FIG. 5B is a diagram showing a map table when the content 2 is synchronously processed, and FIG. 8C is a diagram when the content 2 is synchronously processed. It is a figure which shows the title management table.

  As shown in FIG. 10A, in the virtual disk image, the content 2 is recorded with the virtual address “0x250” as the head address. At this time, since the content 1 can be recorded on the disc 1 with “0x250” as the head address, the content 2 is recorded on the disc 1 with the address “0x250” of the disc 1 as the head address.

  When the synchronization processing of the content 2 is completed, as shown in FIG. 10B, the synchronization flag of the map table recorded in the map information of the entry 1 indicates that the content is recorded on the My Disk. 1 ". Further, as shown in FIG. 10C, in the title management table of the disc 1 recorded in the storage unit 280, the remaining dubbing count in the title 2 is decremented by 1 to “9” times, and the synchronization state Is changed to information indicating synchronization.

  Next, with respect to the synchronization processing of the content 2 when the content (content 3) having “0x250” as the head address has already been recorded on the disc 1, the following will be described with reference to FIGS. explain.

  11A to 11D are diagrams showing the states of the storage unit 340 and the storage unit 280 when the content 2 is synchronously processed. FIG. 11A shows the start address of the content 2 in the virtual disk image. FIG. 7 is a diagram showing a state where content 3 as an address is recorded on the disc 1, (b) is a diagram showing a state where the virtual disc image is changed so that the content 2 follows the content 3, and (c). It is a figure which shows the map table at the time of synchronizing the content 2, (d) is a figure which shows the title management table at the time of synchronizing the content 2. FIG.

  As shown in FIG. 11A, when content 3 having a head address “0x250”, which is the head address of content 2 in the virtual disk image, is already recorded on the disk 1, the address “0x250” of the disk 1 is recorded. The content 2 cannot be recorded on the disc 1 with the leading address.

  At this time, the drive control unit 320 can record the content 2 on the disc 1 by changing the virtual disc image in the storage unit 340. That is, the drive control unit 320 sets the content 3 recorded with the address “0x250” as the head address in the disk 1 so that the virtual address “0x250” is recorded as the head address in the virtual disk image. The content 2 is set to follow the content 3 so that the virtual address “0x400” is recorded as the head address. That is, the drive control unit 320 changes the virtual disk image in the area 1. Thus, in the changed virtual disk image, the start address of the content 2 is “0x400”, so that the content 2 can be recorded on the disk 1 with “0x400” as the start address.

  At this time, the map table of region 1 is also changed as shown in FIG. That is, the top address of the content 2 in the virtual disc map is “0x400”, which is “1” indicating that the content is recorded on the My Disc. Also, in the virtual disk map, the content 3 having a head address “0x250” and a content capacity of YGB is registered. Since the content 3 is content that is not recorded in the area 1, the start address is not recorded in the memory map, and the synchronization flag is not recorded.

  Similarly, as shown in FIG. 11D, in the title management table of the disc 1 in the storage unit 280, the synchronization state associated with the title 2 is changed to information indicating synchronization, and the title 3 indicating the content 3 is displayed. Information (reproduction time and reproduction image quality) associated with is registered. At this time, the content 3 is content recorded only on the disc 1 and cannot be dubbed, so the remaining number of times of dubbing in the title 3 is not displayed.

(Delete contents recorded in area 1)
When the free space of the area 1 in the storage unit 340 is reduced, the content recorded in the area 1 may be deleted. The deletion of the content recorded in the area 1 may be executed according to a user instruction, or may be automatically executed when the free space in the area 1 becomes a predetermined value or less. Good.

  FIG. 12 is a diagram illustrating a state of the storage unit 340 and the disk 1 when the content 4 is newly recorded after the content 1 and the content 2 recorded in the area 1 are deleted. In FIG. 12, the content 4 is also recorded on the disc 1 for recording in a state where the My Disc is loaded.

  The states shown in FIG. 12, that is, the states of the storage unit 340 and the storage unit 280 when the content 4 is recorded in the region 1 after deleting the content 1 and the content 2 from the region 1, are shown in FIGS. The following will be described with reference to FIG. 13A to 13C are diagrams showing the states of the storage unit 340 and the storage unit 280 when the content 4 is recorded. FIG. 13A shows the recording state of the content in the area 1 of the storage unit 340. It is a figure which shows the corresponding relationship of the recording state of the corresponding disc 1, (b) is a figure which shows the map table at the time of recording the content 4, (c) is a title management table at the time of recording the content 4 FIG.

  When the content 1 and the content 2 are deleted from the area 1, the drive control unit 320 deletes information regarding the content 1 and the content 2 from the memory map in the map table recorded in the entry 1 of the storage unit 340. The drive control unit 320 also deletes the synchronization flag associated with the contents 1 and 2. However, as shown in FIG. 13A, the contents 1 and 2 remain on the virtual disk image without being erased. That is, as shown in FIG. 13B, even if the contents 1 and 2 are deleted from the area 1, the information on the contents 1 and 2 is not deleted from the virtual disk map in the map table. It will be.

  Therefore, the drive control unit 320 instructs the disk drive unit 330 to record the content 4 so as to follow the content 2 already recorded in the virtual disk image, that is, the virtual address “0x650”.

  Further, as shown in FIG. 13C, the title management table in the storage unit 280 is also changed as the contents 1 and 2 are deleted from the area 1. When the content 1 and the content 2 recorded in the area 1 are deleted, the back-end control unit 240 deletes information indicating the remaining number of dubbing times and the synchronization state of the content 1 and the content 2 in the title management table in the storage unit 280. To do. Next, when the content 4 is recorded in the area 1, the back-end control unit 240 registers information related to the title (title 4) indicating the content 4 in the title management table.

<Content playback operation>
Next, the content reproduction operation in the recorder apparatus 100 will be described below with reference to FIGS.

  The content reproduction process is a process executed in response to a content reproduction instruction from the user via the operation input unit. For example, when the user selects playback of a title displayed on the display device, the back-end control unit 240 executes the content playback process on the assumption that the playback instruction of the content represented by the selected title has been received. Note that the title displayed on the display device is a title recognized by the back-end unit 200. The title recognized in the back-end unit 200 can be rephrased as the title registered in the title management table recorded in the title management area of the storage unit 280.

  Note that the content playback operation in the recorder apparatus 100 can be broadly divided into playback processing when a My Disc is loaded and playback processing when a My Disc is not loaded. Each reproduction process will be described below.

(Playback process when My Disc is loaded)
Reproduction processing when a My Disk is loaded will be described below with reference to FIGS. FIG. 14 is a diagram illustrating a state of the storage unit 340 and the storage unit 280 when the disc 1 on which the contents 1 to 3 are recorded is loaded. FIG. 15 is a diagram schematically showing a medium from which content is read during reproduction when a My Disc is loaded.

  As shown in FIG. 14, the disc 1 on which the contents 1 to 3 are recorded is loaded in the drive unit 300, and the contents 1 and 2 are recorded in the area 1 of the storage unit 340. Therefore, information on titles 1 to 3 is recorded in the title management table in the title management area of the storage unit 280. That is, the back end unit 200 can recognize the contents 1 to 3 represented by the titles 1 to 3. In FIG. 14, the details of the title management table are omitted.

  As a playback process when the My Disc is loaded, the playback process when the content 1 recorded in both the disc 1 and the area 1 is played back will be described first and then recorded on the disc 1. However, a reproduction process in the case of reproducing the content 3 not recorded in the area 1 will be described.

  The back-end control unit 240 outputs a command for reading the content 1 recorded on the disc 1 to the drive unit 300 via the interface unit 290. The drive control unit 320 that has received a command from the back-end control unit 240 refers to the map table and determines whether or not the content 1 recorded on the disc 1 is recorded in the area 1. At this time, since the content 1 is the content recorded in the area 1, the drive control unit 320 reads the read command from the disc 1 received from the back-end control unit 240 from the area 1 with reference to the map table. Is converted into a read instruction. That is, the drive control unit 320 converts the address of the disk 1 into the physical address of the area 1 with reference to the map table.

  The drive control unit 320 that has read the content 1 from the area 1 outputs the read content 1 to the back-end unit 200 via the interface unit 310.

  As described above, when the content to be read is recorded on both the My Disc and the storage unit 340, the content is read from the storage unit 340 as shown in FIG.

  Similarly, when playing back the content 3 recorded on the disc 1 but not recorded in the area 1, the back-end control unit 240 sends an instruction for reading the content 3 recorded on the disc 1 to the interface unit 290. To the drive unit 300. The drive control unit 320 that has received a command from the back-end control unit 240 refers to the map table and determines whether or not the content 3 recorded on the disc 1 is recorded in the area 1. At this time, since the content 3 is content not recorded in the area 1, the drive control unit 320 sends the content 3 to the disc drive unit 330 in accordance with the read command from the disc 1 received from the back-end control unit 240. Is to be read.

  When the content 3 is read from the disc 1, the drive control unit 320 outputs the read content 3 to the back end unit 200 via the interface unit 310.

  As described above, when the content to be read is not recorded in the storage unit 340, the content is read from My Disk as shown in FIG.

(Playback process when My Disk is not loaded)
Next, the reproduction process in the case where no my disk is loaded will be described below with reference to FIGS. FIG. 16 is a diagram illustrating a state of the storage unit 340 and the storage unit 280 when no optical disk is loaded in the drive unit 300. FIG. 17 is a diagram schematically showing a medium from which content is read out during reproduction when no My Disc is loaded.

  As shown in FIG. 16, content 1 and content 2 are recorded in area 1 of storage unit 340. However, unlike the case of FIG. 14, the disc 1 on which the contents 1 to 3 are recorded is not loaded in the drive unit 300. Note that information on titles 1 to 3 is recorded in the title management table in the title management area of the storage unit 280. That is, the back end unit 200 can recognize the contents 1 to 3 represented by the titles 1 to 3. In FIG. 16, as in FIG. 14, details of the title management table are omitted.

  In the case of the state shown in FIG. 16, among the contents 1 to 3 represented by the titles 1 to 3 recognized in the back end unit 200, the contents 1 and 2 recorded in the area 1 of the storage unit 340. Can be reproduced, but the content 3 recorded only on the disc 1 cannot be reproduced.

  That is, as shown in FIG. 17, when the content to be read is recorded on both the My Disc and the storage unit 340, the content is stored by the same processing as when the My Disc is loaded. Read from the unit 340. However, content recorded only on the disc 1 cannot be read.

  The content 1 reading process shown in FIG. 17 is the same as the content 1 reading process in the case where the My Disc is loaded, and thus the description thereof is omitted here.

<Content editing operation>
Next, the content editing operation in the recorder apparatus 100 will be described below with reference to FIGS. 18 and 19A and 19B.

  The content editing process is a process executed in response to a content editing instruction from the user via the operation input unit. For example, when the user selects to edit the title displayed on the display device, the back-end control unit 240 edits the content selected by the user on the assumption that the back-end control unit 240 has received an instruction to edit the content represented by the selected title. Execute the process. Note that the title displayed on the display device is a title recognized by the back-end unit 200. The title recognized in the back-end unit 200 can be rephrased as the title registered in the title management table recorded in the title management area of the storage unit 280. That is, the title registered in the title management table can be edited regardless of the recording medium.

  Similar to the content reproduction process, the content editing operation in the recorder apparatus 100 can be broadly divided into an editing process when a my disk is loaded and an editing process when a my disk is not loaded. Each editing process will be described below.

  The content editing process is a process of changing at least a part of the data recorded in the My Disc or the storage unit 340. Specifically, the content is deleted from the scene (partial change of the content data). ), Processing including deletion of content and addition of chapter in content. Note that, here, scene erasure in the content will be described as an example, but other processing can be similarly performed.

(Editing process when My Disc is loaded)
The editing process when a My Disk is loaded will be described below with reference to FIGS. FIG. 18 is a diagram schematically showing a medium on which content is edited when a My Disc is loaded.

  As shown in FIG. 14, the disc 1 on which the contents 1 to 3 are recorded is loaded in the drive unit 300, and the contents 1 and 2 are recorded in the area 1 of the storage unit 340. The title management table in the title management area of the storage unit 280 stores information on the titles 1 to 3, and the back end unit 200 recognizes the contents 1 to 3 represented by the titles 1 to 3. Can do. In FIG. 14, the details of the title management table are omitted.

  As a reproduction process in the case where the My Disc is loaded, the process in the case of editing the content 1 recorded in both the disc 1 and the area 1 will be described first, and then recorded on the disc 1. A process in the case of editing the content 3 not recorded in the area 1 will be described.

  The back-end control unit 240 outputs an instruction to change the data of the content 1 recorded on the disc 1 to the drive unit 300 via the interface unit 290. The drive control unit 320 that has received a command from the back-end control unit 240 refers to the map table and determines whether or not the content 1 recorded on the disc 1 is recorded in the area 1. At this time, since the content 1 is the content recorded in the area 1, the drive control unit 320 refers to the map table for an instruction to change data in the disc 1 received from the back-end control unit 240. 1 is converted into an instruction to change data. That is, since the drive control unit 320 refers to the map table and converts the address of the disc 1 into the physical address of the area 1, the data of the content 1 recorded in the area 1 is actually changed. It will be.

  As described above, when the content whose data is to be changed is recorded in both the My Disc and the storage unit 340, the data of the content recorded in the storage unit 340 is changed as shown in FIG. It will be.

  However, since the content 1 recorded in the disc 1 and the content 1 recorded in the area 1 remain different (asynchronous state), the drive control unit 320 records in the area 1. The data change made for the content 1 is also reflected on the content 1 recorded on the disc 1. Reflecting the change to the content 1 recorded on the disc 1 may be performed at any time until the disc 1 is taken out from the drive unit 300.

  Similarly, when the data of the content 3 recorded in the disc 1 but not recorded in the area 1 is changed, the back end control unit 240 similarly changes the data of the content 3 recorded in the disc 1. Is output to the drive unit 300 via the interface unit 290. The drive control unit 320 that has received a command from the back-end control unit 240 refers to the map table and determines whether or not the content 3 recorded on the disc 1 is recorded in the area 1. At this time, since the content 3 is content not recorded in the area 1, the drive control unit 320 follows the instruction to change the data of the content 3 recorded on the disc 1 received from the back-end control unit 240. Instructs the disk drive unit 330 to change the data of the content 3.

(Editing process when My Disk is not loaded)
Next, content editing processing when no My Disc is loaded will be described below with reference to FIGS. 16 and 19A and 19B. FIGS. 19A and 19B are diagrams schematically showing a medium on which content is edited when the My Disc is not loaded. FIG. 19A is a diagram when the Disc 1 is not loaded. (B) shows the reflection of the changed portion on the disk 1 when the disk 1 is loaded.

  In the case of the state shown in FIG. 16, among the contents 1 to 3 represented by the titles 1 to 3 recognized in the back end unit 200, the contents 1 and 2 recorded in the area 1 of the storage unit 340. The same editing process as when the disc 1 is loaded can be performed.

  That is, as shown in FIG. 19B, when the content 2 of the disc 1 is changed in another recorder device, the drive control unit 320 records the change of the content 2 in the disc 1 in the area 1. It is reflected to the content 2 that is present. At this time, the map table recorded in entry 1 is also updated.

<Content copy operation>
Next, a content copy operation in the recorder apparatus 100 will be described below with reference to FIGS. 20 (a) and 20 (b). Here, the in-memory copy operation in the storage unit 340 in the recorder apparatus 100 will be described as an example. The in-memory copy operation can also be referred to as an in-memory dubbing operation in the recorder apparatus 100. 20A and 20B are diagrams illustrating the in-memory copy process in the recorder device 100, and FIG. 20A is a diagram illustrating the state of the storage unit 340 after the in-memory copy process. ) Is a diagram showing the state of the title management area in the storage unit 280 after the in-memory copy process.

  The content in-memory copy process is a process executed in response to a content copy instruction from the user via the operation input unit. For example, when the user selects a title from the titles displayed on the display device and determines in which area the selected title is to be copied, the back-end control unit 240 displays the content represented by the selected title. When an instruction to copy to the area in the selected storage unit 340 is received, the in-memory copy process of the content is executed. Note that the title displayed on the display device is a title recognized by the back-end unit 200. The title recognized in the back-end unit 200 can be rephrased as the title registered in the title management table recorded in the title management area of the storage unit 280.

  Upon receiving an instruction from the user to copy the content 2 recorded in the area 1 of the storage unit 340 to the area 2 of the storage unit 340, the back-end control unit 240 is recorded in the area 1 with respect to the drive control unit 320. The content 2 is recorded in the area 2. Upon receiving the instruction from the back-end control unit 240, the drive control unit 320 records the content 2 in the area 2 as shown in FIG. At this time, the drive control unit 320 updates the map table recorded in the entry 2. The recording of the content 2 in the area 2 and the update of the map table associated therewith are the same as the processing described in the recording operation, and thus the description thereof is omitted.

  When the recording of the content 2 in the area 2 is completed, the back-end control unit 240 subtracts 1 from the remaining dubbing count of the content 2 in the title management information recorded in the title management area of the disc 1 in the storage unit 280. Further, 1 is added to the remaining dubbing count of the content 2 in the title management information recorded in the title management area of the disc 2 in the storage unit 280. Accordingly, as shown in FIG. 20B, the remaining dubbing count of the content 2 in the title management area of the disc 1 is “8”, and the remaining dubbing count of the content 2 in the title management area of the disc 2 is “1”. It becomes.

  As shown in FIG. 20A, since the disc 2 is not loaded in the drive unit 300, the synchronization state of the content 2 recorded in the area 2 is information indicating unsynchronization.

<Unregister My Disk>
Next, the registration cancellation process of My Disk will be described. The drive control unit 320 that has received an instruction to cancel the registration of the disk 1 from the user erases the management information that is recorded in the storage unit 340 and manages the area associated with the disk 1 that is to be deregistered. That is, the media ID information, the media key information, and the map information in the entry are deleted, and the allocation flag is changed to “0” indicating that the allocation is not performed. If data is recorded in the area, the recorded data is also erased. As a result, the entry in the storage unit 340 is in a state where a new My Disk can be registered.

  Further, the back-end control unit 240 that has received the instruction to cancel the registration of the disc 1 from the user deletes the title management information recorded in the title management area of the disc 1 in the storage unit 280. As a result, the back end unit 200 cannot recognize the title indicating the content recorded on the disc 1.

(Using the file system of My Disk)
In the recorder device 100, it is preferable to use a file system acquired from an optical disk registered as My Disk for writing data to and reading data from the optical disk registered as My Disk.

  Here, data management using the file system of the optical disc will be described below with reference to (a) to (c) of FIG. 21A to 21C are diagrams showing data management using a file system. FIG. 21A shows an example of a file system recorded in the storage unit 280. FIG. FIG. 4C shows a correspondence relationship between the recording states of the disc 1 corresponding to the recording states of contents in FIG.

  Normally, a file system defined by a standard for each type of optical disk is recorded in the optical disk, and each file recorded on the optical disk is associated with the recorded address of each file by the file system. ing. The file system is often recorded at the beginning of the recording area of the optical disc.

  The back-end unit 200 refers to the file system acquired from the optical disk in order to specify the address of the optical disk that is the target of data reading or data writing. The file system is acquired together with the media ID and the like when the optical disc is loaded, and is stored in the volatile memory of the back end unit 200. Further, in order to cope with an unexpected power interruption, the acquired file system is also stored in the storage unit 280 ((a) of FIG. 21). The back-end unit 200 acquires a file system from the optical disk every time an optical disk is loaded, and compares the acquired file system with the file system recorded in its own apparatus to maintain the latest state of the file. I am doing so.

  That is, the back-end unit 200 compares the file system read from the optical disk registered as My Disk with the file system already recorded in the storage unit 280 (the file system most recently read from the optical disk). As a result, the back-end unit 200 acquires content information recorded on the optical disc and not recorded in the storage unit 340 (for example, the address of the optical disc on which the content is recorded, title information indicating the content, etc.).

  In FIG. 21A, only the file system related to the disk 1 is shown, but the file system is recorded in the file system management area of the storage unit 280 by the number of disks registered as my disks. ing.

  Thus, by recording the file system of the optical disc registered as My Disc in the storage unit 280, the back end unit 200 is recorded in the storage unit 280 even when the optical disc is not loaded. The file on the virtual disk image can be accessed by referring to the existing file system. That is, even when the My Disk is not loaded, the data can be handled as if the My Disk is loaded. For example, in the map information of the storage unit 340, when the address of the storage unit 340 corresponding to the virtual address to be accessed is recorded, the data recorded at the address using the address of the storage unit 340 Can be read out.

  Further, as shown in (b) and (c) of FIG. 21, even when the content 1 is divided into a plurality of fragmented files and recorded on the optical disc, the back-end control unit 240 By referring to the arrangement information of the content 1 in the file system recorded in the storage unit 280, the content 1 can be accurately accessed.

  As described above, the map information recorded in the storage unit 340 is shown as arrangement information for each content in the present embodiment, but more precisely, as shown in FIG. ) Shows the arrangement information for each.

  In addition, when the registration of My Disk is canceled, the file system recorded in the file system management area is also deleted together with the title management information.

<Example of display on display device>
Finally, a display example of content and information recorded in the title list on the display device connected to the recorder device 100 will be described below with reference to FIG. FIG. 22 is a diagram schematically showing display of information recorded in the content and title list on the display device 500.

  When the user instructs the recorder apparatus 100 to display a title list via the operation input unit, the display apparatus 500 displays the title list and content as shown in FIG.

  That is, as shown in FIG. 22, the display screen in the display device 500 includes two screens: a content display unit 510 that continues to display content that has been viewed so far, and a title list display unit 520 that displays a title list. Will be divided.

  The title list display unit 520 displays tabs corresponding to registered My Disks as shown in FIG. When the user selects the tab of the My Disc for which the title list is desired to be confirmed, the title list display unit 520 displays the title list of the My Disc selected by the user. That is, the information of the title management table recorded in the title management area of each My Disc in the storage unit 280 is displayed.

  FIG. 22 shows a title list when the tab of the disc 1 is selected. At this time, it is preferable to display information (icon) indicating the selected disk on the display unit 530. When the user selects each title displayed on the title list display unit 520, it is preferable to display a thumbnail of the content indicated by the temporarily selected title on the display unit 530.

(Details of how to determine synchronization target content)
Next, details of a method for determining content to be synchronized in the recorder apparatus 100 will be described below with reference to FIG. FIG. 23 is a flowchart showing details of the synchronization processing in the recorder apparatus 100. In the following embodiment, the information recorded in the storage unit 280 and the content recorded in the storage unit 340 are read out from the storage unit 280 area and the storage unit 340 area corresponding to the loaded my disk. Shall.

  First, when a my disk is loaded in the drive unit 300, the back-end control unit 240 selects one piece of reservation information from the reservation information management area of the storage unit 280 (step S1). The back-end control unit 240 determines whether reservation information that matches the selected reservation information is recorded on the My Disk (step S2). In other words, it can be said that it is determined whether or not designation information for designating a certain content recorded in the recorder device 100 is recorded on the My Disc.

  When reservation information that matches the selected reservation information is recorded on the My Disc (Yes in step S2), the back-end control unit 240 retrieves the content specified by the selected reservation information from the storage unit 340 of the drive unit 300. read out. Then, the back end control unit 240 instructs the drive control unit 320 to record the read content on the My Disc. Upon receiving the instruction, the drive control unit 320 records the content on the My Disc (step S3). When the recording of the content on the My Disc is completed, the drive control unit 320 deletes the content recorded on the My Disc from the storage unit 340 (Step S4).

  On the other hand, when reservation information that matches the selected reservation information is not recorded on the My Disc (No in step S2), the back-end control unit 240 uses the reservation information selected for the drive control unit 320 of the drive unit 300. Instructs deletion of specified content. Receiving the instruction, the drive control unit 320 erases the content from the storage unit 340 (step S5).

  Subsequently, the back-end control unit 240 deletes the selected reservation information from the reservation information management area of the storage unit 280 (step S6).

  When the processing for all the reservation information related to the loaded My Disk recorded in the reservation information management area of the storage unit 280 is completed (Yes in step S7), the back-end control unit 240 performs content synchronization processing. finish. If the processing for all the reservation information related to the loaded My Disk recorded in the reservation information management area of the storage unit 280 has not been completed (No in step S7), the back-end control unit 240 The reservation information is selected, and the processing from step S2 is executed again.

  In the above-described synchronization processing, the content recorded on the My Disk is erased from the storage unit 340, but of course it may not be erased.

(Advantages of the recorder device 100)
As described above, the recorder device 100 synchronizes by determining whether or not the reservation information recorded in the storage unit 280 matches the reservation information recorded in the loaded My Disk. The content to be processed is detected.

  Here, the time required to determine whether or not the reservation information that matches the reservation information recorded in the storage unit 280 is recorded on the My Disk is the time required to compare the content streams themselves. Short compared.

  Therefore, the recorder apparatus 100 can reduce the time required for recording the content recorded in the storage unit 340 on the loaded My Disc (that is, the time required for the synchronization process).

  Furthermore, by deleting the reservation information specifying the synchronized content from the storage unit 280, it is possible to easily avoid the content already recorded on the My Disk being recorded again. Further, by deleting the reservation information for designating the synchronized content from the My Disk, it is possible to avoid the content that has already been recorded in another recorder device being recorded again. Further, it is possible to avoid the area where the reservation information is recorded in the My Disk being full.

  In the recorder device 100, the content is recorded only on the My Disk associated with the area where the content is recorded. In other words, the recorder apparatus 100 can prevent content from being accidentally recorded on an optical disc for which content recording is not desired.

(Reservation information and content status before and after synchronization)
Here, reservation information and content states before and after the above-described synchronization processing will be described below with reference to FIGS. 24 and 25. FIG. 24 and 25 are diagrams showing the reservation information and the state of the content before and after the synchronization process in the recorder apparatus 100, FIG. 24 is a state before the synchronization process, and FIG. 25 is a state after the synchronization process. . Hereinafter, changes in the reservation information and the recording state of the content before and after the synchronization process will be described classified for each case. 24 and 25 are not shown for the sake of convenience, the reservation information is recorded in the storage unit 280, and the content is recorded in the storage unit 340. 24 and 25, only the reservation information recorded in the reservation management area associated with the disk 1 is shown for convenience of explanation.

(Case 1: When the reservation information matches and the content is recorded in the recorder device)
First, FIG. 24 shows a case where reservation information matching the reservation information recorded in the recorder device 100 is recorded on the disc 1 and the content specified by the reservation information is recorded in the recorder device 100. “Reservation 1” shown will be described as an example. In this case, “reservation 1” is recorded in the storage unit 280 of the recorder apparatus 100, and “town walking” that is a content recorded based on “reservation 1” is recorded in the storage unit 340.

  Here, as shown in FIG. 24, “Reservation 1” is recorded on the disk 1, and “City walk” is recorded on the storage unit 340, so the recorder device 100 sets “City walk” to the disk. Record in 1.

  Further, the recorder device 100 deletes “Reservation 1” recorded in the storage unit 280 and the disk 1 and deletes “town walking” from the storage unit 340.

  As a result, after the synchronization process, “Reservation 1” is erased from the storage unit 280 and the disk 1 of the recorder device 100 and “town walking” is erased from the storage unit 340 of the recorder device 100 as shown in FIG. It will be in the state. Then, “town walking” is recorded on the disc 1.

  Note that the reservation IDs in FIGS. 24 and 25 are identification information for associating reservation information with the content designated by the reservation information. The content recording execution time may fluctuate due to reasons such as extension of the previous program. Therefore, by recording the same reservation ID as the reservation information as information indicating the content, even if the scheduled recording time in the reservation information is different from the recording execution time of the content, the reservation information Association with content can be performed.

(Case 2: When the reservation information does not match and the content is recorded in the recorder device)
Next, FIG. 24 shows a case where reservation information that matches the reservation information recorded in the recorder device 100 is not recorded in the disc 1, but the content specified by the reservation information is recorded in the recorder device 100. The “reservation 2” shown will be described as an example. In this case, “Reservation 2” is recorded in the storage unit 280 of the recorder device 100, and “world car window” that is the content recorded based on “Reservation 2” is recorded in the storage unit 340. However, as shown in FIG. 24, “Reservation 2” is not recorded on the disc 1. However, “world car window” is recorded on the disc 1.

  In this case, it is conceivable that the disc 1 is a “world car window” synchronously processed by another recorder device.

  In this case, since the reservation information does not match, the recorder apparatus 100 deletes “reservation 2” from the storage unit 280. Further, “world car window” is deleted from the storage unit 340.

  Thus, after the synchronization process, “Reservation 2” is deleted from the storage unit 280 of the recorder device 100 and “world vehicle window” is deleted from the storage unit 340 of the recorder device 100, as shown in FIG. It becomes a state. The state of the disk 1 does not change.

  As described above, in the recorder apparatus 100, by deleting “Reservation 2”, a process of recording “world car window”, which is the content already recorded on the disc 1, to the disc 1 again occurs. Can be avoided.

(Case 3: When the reservation information matches and the content is not recorded on the recorder device)
Next, reservation information that matches the reservation information recorded in the recorder device 100 is recorded on the disc 1, but the content specified by the reservation information is not recorded in the recorder device 100 as shown in FIG. The “reservation 3” shown will be described as an example. Here, it is assumed that the scheduled recording date and time set in “Reservation 3” is the past date and time.

  In this case, “Reservation 3” is recorded in the storage unit 280 of the recorder apparatus 100, but the content recorded based on “Reservation 3” is not recorded in the storage unit 340.

  As this case, a case where the recording of the content designated by “Reservation 3” in the recorder apparatus 100 has failed can be considered.

  In this case, although the reservation information matches, the content to be recorded on the disc 1 is not recorded in the storage unit 340, so that the recording of the content designated by “Reservation 3” is not executed. Therefore, recorder device 100 deletes “reservation 3” from storage unit 280.

  Here, since the content designated by “Reservation 3” is not synchronized with the disc 1, “Reservation 3” recorded on the disc 1 is not deleted. As a result, the synchronization process can be executed when the content designated by “Reservation 3” is recorded in another recorder device.

  As a result, as shown in FIG. 25, “Reservation 3” is deleted from the storage unit 280 of the recorder device 100. The state of the disk 1 does not change.

  Of course, if the scheduled recording date and time set in “Reservation 3” is a date and time later than the current date and time, the reservation information is left as it is without being erased. It is assumed that the current date and time is acquired from date and time information in a timer mounted on the recorder device 100.

  As described above, in the recorder device 100, by deleting “Reservation 3” in which no content is recorded in the storage unit 340, the process for “Reservation 3” is performed again when the disc 1 is loaded next time. Can be avoided. That is, in the recorder device 100, it is possible to prevent the time required for the synchronization process from increasing from the next time.

(Case 4: The reservation information does not match and the content is not recorded on the disc)
Finally, FIG. 24 shows a case where reservation information that matches the reservation information recorded in the recorder device 100 is not recorded on the disc 1 and the content specified by the reservation information is not recorded on the disc 1. “Reservation 4” will be described as an example. In this case, “Reservation 4” is recorded in the storage unit 280 of the recorder apparatus 100, but “Reservation 4” and “Program introduction” that is the content designated by “Reservation 4” are not recorded on the disc 1. .

  In this case, the “program introduction” is synchronized with the disc 1 in another recorder device, but the “program introduction” is erased from the disc 1 before being loaded into the recorder device 100.

  In this case, since the reservation information does not match, the recorder device 100 deletes “reservation 4” from the storage unit 280 as in the case 2. In addition, “program introduction” is deleted from the storage unit 340.

  Thus, after the synchronization process, “Reservation 4” is deleted from the storage unit 280 of the recorder device 100 and “Program introduction” is deleted from the storage unit 340 of the recorder device 100 as shown in FIG. It becomes a state. The state of the disk 1 does not change.

  As described above, in the recorder apparatus 100, by deleting “Reservation 4”, it is possible to avoid that “Program Introduction”, which is the content already deleted from the disc 1, is recorded on the disc 1 again. it can.

(Synchronization processing of content recorded by schedule reservation)
The synchronization process described above is a process of content recorded based on reservation information for executing a single recording reservation. Here, unlike the reservation information for executing a single recording reservation, the case where the content recorded by the reservation information for executing the schedule reservation is synchronously processed will be described below.

  Here, “schedule reservation” in this specification and the like refers to reservation information including a plurality of recording execution date and time information. Therefore, the recording execution date / time information in the schedule reservation may be periodic date / time information (for example, the same time every day or the same time every week), or may be arbitrary date / time information.

  When synchronizing the content recorded by schedule reservation, the memory | storage part 280 in the recorder apparatus 100 has an area | region which records recording reservation failure information. The recording reservation failure information is information indicating reservation information for which recording was not executed in the schedule reservation.

  Note that the recording reservation failure information may be provided as a part of the reservation information management area described above, or may be provided in the storage unit 280 as another area. When the area for recording the recording reservation failure information is provided as an area different from the reservation information management area, it is provided for each My Disk as in the reservation information management area.

  In addition, when synchronizing the content recorded by schedule reservation, the optical disc has an area for recording synchronization management information.

  The synchronization management information is information including synchronization date and time information indicating the last date and time when the synchronization processing is executed and synchronization content information that specifies the content on which the synchronization processing is to be executed. Further, these pieces of information in the synchronization management information are recorded for each schedule reservation. That is, for example, when two schedule reservations, reservation A and reservation B, are recorded on the optical disc, synchronization date information and synchronization-required content information are recorded as synchronization management information in reservation A and reservation B, respectively. .

  Next, details of the synchronization processing of content recorded by schedule reservation will be described below with reference to FIGS. 26 and 27. FIG. 26 and 27 are diagrams showing the reservation information and the state of the content before and after the synchronization process in the recorder apparatus 100. FIG. 26 shows the state before the synchronization process of the content recorded by the schedule reservation. Is a state after synchronization processing of the content recorded by the schedule reservation. Although not shown in FIGS. 26 and 27 for convenience, the reservation information is recorded in the storage unit 280 and the content is recorded in the storage unit 340. 26 and 27, only the reservation information recorded in the reservation management area associated with the disk 1 is shown for convenience of explanation.

  As shown in FIG. 26, in the storage unit 280 of the recorder apparatus 100, two pieces of reservation information, reservation A (weekly reservation) and reservation B (daily reservation) are recorded. In addition, in the storage unit 340 of the recorder device 100, “Western Theater” (with 09/04/02), which is the content recorded based on the reservation A, and the content recorded based on the reservation B, “ “Drama” (with 09/3/31) and “Drama” (with 09/04/03) are recorded.

  Also, on the disk 1, two schedule information, reservation A (weekly reservation) and reservation B (daily reservation), are recorded as schedule reservations. “Western theater” (with 09/03/26), which is the content designated by the reservation A, is recorded.

  Even in the case of the schedule reservation, the recorder device 100 records whether or not the reservation information that matches the reservation information recorded in the storage unit 280 is recorded on the My Disk loaded in the same manner as the synchronization process described above. Is executed (that is, the process of step S1). Hereinafter, a synchronization process when reservation A is selected in the recorder apparatus 100 and a synchronization process when reservation B is selected will be described.

(Case 1: Reservation A synchronization process)
First, a synchronization process when the back-end control unit 240 in the recorder device 100 selects the reservation A among schedule reservations recorded in the storage unit 280 will be described.

  The back-end control unit 240 determines that the schedule reservation that matches the reservation A is recorded on the disk 1 and instructs the drive unit 300 to read the synchronization management information related to the reservation A from the disk 1. When the drive unit 300 that has received the instruction reads the synchronization management information from the disk 1, the back-end control unit 240 uses the synchronization date and time information in the read synchronization management information (final synchronization date and time in FIG. 26; 09/03/26). Also, “Western Theater” (with 09/04/02), which is the content that was recorded later, is read from the drive unit 300.

  The back-end control unit 240 instructs the drive unit 300 to record the read “Western theater” (with 09/04/02) on the disc 1. Upon receiving the instruction, the drive control unit 320 records “Western Theater” (with 09/04/02) on the disc 1. When the recording of “Western Theater” (with 09/04/02) on the disk 1 is completed, the drive control unit 320 deletes the “Western Theater” (with 09/04/02) from the storage unit 340.

  Further, the back-end control unit 240 instructs the drive unit 300 to record the date and time information on which the synchronization processing has been performed on the disk 1. The drive control unit 320 in the drive unit 300 updates information on the last synchronization date / time in the synchronization management information of the disk 1. The date and time information to be updated is date and time information indicated by a timer in the recorder apparatus 100.

  At this time, unlike the case of single-time reservation information, the back-end control unit 240 does not delete the reservation A from the storage unit 280 and the disk 1.

  As a result of such processing, as shown in FIG. 27, “Western Theater” (with 09/04/02) is erased from the recorder device 100, and “Western Theater” (with 09/04/02) is stored on the disc 1. It is in a recorded state. Further, the last synchronization date and time of the reservation A is updated to (09/04/02) as shown in FIG.

(Case 2: Synchronization processing for reservation B)
Next, a synchronization process when the back-end control unit 240 in the recorder device 100 selects the reservation B among the schedule reservations recorded in the storage unit 280 will be described.

  Even when the reservation B is selected, as in the case of the reservation A, the back-end control unit 240 determines that the schedule reservation that matches the reservation B is recorded on the disk 1, and synchronizes the reservation B from the disk 1. The drive unit 300 is instructed to read the management information. When the drive unit 300 that has received the instruction reads the synchronization management information from the disk 1, the back-end control unit 240 uses the synchronization date and time information in the read synchronization management information (last synchronization date and time in FIG. 26; 09/04/01). “Drama W” (with 09/04/03), which is the content that was recorded later, is read from the drive unit 300 and recorded on the disc 1. Since this process is the same as the above-described reservation A synchronization process, description thereof is omitted here.

  Since the synchronization management information recorded on the disc 1 includes synchronization-necessary content information (date / time information of synchronization-necessary content in FIG. 26; 09/03/31), the back-end control unit 240 requires synchronization. It is determined whether or not there is a “drama W” recorded on the date (09/03/31) recorded as the content information.

  As shown in FIG. 26, since “drama W” (with 09/03/31) is recorded in the storage unit 340 of the recorder device 100, the back-end control unit 240 sets “drama W” (09/03). / 31) is read from the drive unit 300. Then, the back end control unit 240 instructs the drive unit 300 to record on the disc 1.

  Upon receiving the instruction, the drive control unit 320 in the drive unit 300 records “Drama W” (with 09/03/31) on the disc 1. When the recording of “Drama W” (with 09/03/31) on the disc 1 is completed, the drive control unit 320 deletes “Drama W” (with 09/03/31) from the storage unit 340.

  The back-end control unit 240 instructs the drive unit 300 to delete the information of (09/03/31) from the synchronization required content information in the synchronization management information of the disc 1. Upon receiving the instruction, the drive control unit 320 in the drive unit 300 erases the information of the content synchronization processing (09/03/31) from the disc 1 that requires synchronization.

  At this time, the back-end control unit 240 does not delete the reservation B from the storage unit 280 and the disk 1 as in the case of the reservation A.

  As a result of such processing, as shown in FIG. 27, “Drama W” (with 09/03/31) and “Drama W” (with 09/04/03) are erased from the recorder device 100, and the disc 1 "Drama W" (with 09/03/31) and "Drama W" (with 09/04/03) are recorded. In addition, the last synchronization date and time in the synchronization management information of reservation B is updated to (09/04/03), and (09/03/31) of the synchronization-necessary content information is deleted.

  As described above, the recorder device 100 determines whether or not the reservation information recorded in the storage unit 280 matches the reservation information recorded in the My Disk even in the case of schedule reservation. To do. In the case of schedule reservation, it is determined whether or not the recording execution date and time when the content recording was performed is later than the last synchronization date and time in the synchronization management information. That is, when the reservation information is schedule information, the recorder device 100 detects the contents to be synchronized by determining the above two.

  Here, it is determined whether or not the reservation information recorded on the My Disc matches, and whether or not the recording execution date and time when the content recording is performed is later than the last synchronization date and time in the synchronization management information. It takes a shorter time to determine whether the content data itself is compared.

  Therefore, the recorder device 100 can reduce the time required for the synchronization processing of the content recorded in the storage unit 340 even when the reservation information is a schedule reservation.

  Furthermore, by updating the last synchronization date and time in the synchronization management information to the date and time when the synchronization processing is executed, it is possible to easily avoid the content that has already been subjected to the synchronization processing being recorded on the My Disc again.

  Further, in the recorder apparatus 100, even if the content is recorded on the date and time before the last synchronization date and time in the synchronization management information, if the content is not recorded on the My Disc, the reservation for designating the content is designated. Information is recorded in the storage unit 280, and by determining whether the content is recorded in the storage unit 340, it is detected as a content to be synchronized.

  As a result, even if the content to be recorded is not recorded on the date and time before the last synchronization date and time in the synchronization management information, the content can be synchronized.

(Synchronous content information recording process)
Next, recording processing of the synchronization required content information in the synchronization management information recorded on the disc will be described below with reference to FIGS. Here, the case of reservation B in FIGS. 26 and 27 will be described as an example.

  When the recording of “Drama W” (with 09/04/02), which is the content recorded based on the reservation B, has failed, the recorder device 100 performs date / time information to be recorded as shown in FIG. (09/04/02) is recorded as the recording reservation failure information. At this time, as the recording reservation failure information, date / time information is recorded for each reservation information. That is, the date and time information on the failed recording based on the reservation B is recorded in association with the reservation ID “JKLM” indicating the reservation B.

  When the recording reservation failure information is recorded in the storage unit 280, the back-end control unit 240 in the recorder device 100 uses the date / time information recorded as the recording reservation failure information as the synchronization required content information in the synchronization management information. The drive unit 300 is instructed to record. Upon receiving the instruction, the drive control unit 320 in the drive unit 300 records the synchronization required content information.

  At this time, as shown in FIG. 27, the date / time information recorded as the synchronization management information is recorded in association with the reservation ID “JKLM” of reservation B.

  Further, the back-end control unit 240 deletes the date / time information (09/04/02) recorded as the recording reservation failure information from the storage unit 280.

  Thus, for example, when “Drama W” (with 09/04/02) is recorded on the recorder device when the disc 1 is loaded into another recorder device, “Drama W” ( 09/04/02) can be synchronized.

  It should be noted that the process of recording the synchronization-necessary content information on the disc 1 may be executed after the synchronization process for all schedule reservations is completed.

  In this way, the recorder device 100 can set My Disk so that the content that has failed to be recorded by the own device can be recorded by another recorder device.

(Additional notes)
Here, in the description of the synchronization process described above, single-time reservation information and schedule reservation are described as separate processes, but it is of course possible to execute the synchronization process even when both are mixed. it can. Specifically, the back-end control unit 240 may determine whether the reservation information selected before step S1 in FIG. 23 is a schedule reservation or a single reservation information. In the case of single reservation information, the back-end control unit 240 executes synchronization processing in the case of single reservation information, and in the case of schedule reservation, executes the synchronization processing in the case of schedule reservation. You just have to do it.

  In the present embodiment, the case where the reservation information is recorded in the storage unit 280 is described as an example, but may be recorded in the storage unit 340. In this case, when a recording reservation is set in the recorder apparatus 100, reservation information based on the set information is output to the drive unit 300 via the interface unit 290. The drive control unit 320 in the drive unit 300 records reservation information in a reservation information management area provided in the storage unit 340.

  Further, instead of the interface unit 290, a new interface for exchanging reservation information between the back-end unit 200 and the drive unit 300 may be newly provided.

(Processing for recorder devices that do not have the My Disk function)
In the above-described embodiment, the recorder apparatus 100 (which is also referred to as the recorder apparatus 100 having a my disk function) having an optical disk registered as a my disk and a recording / playback and editing function for the optical disk registered as the my disk is taken as an example. Of course, it is not limited to this. Even a recorder apparatus that does not have a My Disk function can realize the synchronization processing according to the present invention.

  In the case of a recorder device that does not have a my disk function, the back-end control unit also has the function of the drive control unit. In addition, the storage unit 340 that records content is connected to the back-end unit 200.

  First, when an optical disc is loaded in the drive unit, the back-end control unit selects one piece of reservation information from a storage unit (reservation information recording unit) that stores reservation information. The back-end control unit determines whether reservation information that matches the selected reservation information is recorded on the optical disc.

  When reservation information that matches the selected reservation information is recorded on the optical disc, the back-end control unit reads the content specified by the selected reservation information from the storage unit (content storage unit) that stores the content. Recording on an optical disc. When the recording of the content on the optical disc is completed, the back-end control unit deletes the content recorded on the optical disc from the content storage unit.

  On the other hand, when the reservation information that matches the selected reservation information is not recorded on the optical disc, the back-end control unit deletes the content from the content storage unit.

  Subsequently, the back-end control unit deletes the selected reservation information from the reservation information recording unit.

  When the processing for all the reservation information recorded in the reservation information recording unit is completed, the back-end control unit ends the content synchronization process. If the processing for all the reservation information recorded in the reservation information recording unit has not been completed, the back-end control unit selects the next reservation information and executes the synchronization processing again.

  As described above, even if the recorder device does not have the My Disc function, does the reservation information recorded in the content storage unit match the reservation information recorded in the loaded optical disc? By determining whether or not, content to be synchronized is detected. As a result, even a recorder device that does not have a My Disk function can reduce the time required for the synchronization processing of the content recorded in the content storage unit.

  Even when the selected reservation information is a schedule reservation, the same processing as that of the recorder device having the My Disk function can be realized.

[Other variations]
A first program recording apparatus according to the present invention includes a recording means for recording a designated program designated by the recording reservation information recorded in the reservation information recording section on a recording medium that is not removable, and a recording for designating the designated program. When the reservation information is recorded on a removable recording medium and the designated program is recorded on the non-removable recording medium, recording means for recording the designated program on the removable recording medium, and the recording Erasing means for erasing the recording reservation information for designating the designated program recorded on the removable recording medium by the means from the reservation information recording unit.

  In the first program recording apparatus according to the present invention, the recording reservation information recorded in the reservation information recording unit is recorded on a detachable recording medium, and the designated program specified by the recording reservation information is not detachable. If recorded on a recording medium, the designated program is recorded on a removable recording medium.

  As described above, in the first program recording apparatus according to the present invention, whether or not the recording reservation information recorded in the reservation information recording unit matches the recording reservation information recorded in the removable recording medium. The program to be recorded on the removable recording medium is detected.

  Here, the time required to determine whether or not the recording reservation information that matches the recording reservation information recorded in the reservation information recording section is recorded on the removable recording medium is the program (content) data itself. Compared to the time required to compare

  Therefore, in the first program recording apparatus according to the present invention, there is an effect that it is possible to reduce the time required for recording the program recorded on the non-detachable recording medium on the removable recording medium.

  In the first program recording apparatus according to the present invention, the recording reservation information for designating the designated program recorded on the removable recording medium is erased from the reservation information recording unit. As a result, the first program recording apparatus according to the present invention also has an effect that it is possible to easily avoid the program recorded on the removable recording medium from being recorded again.

  The program recording apparatus according to the present invention further comprises registration means for registering the removable recording medium in association with the recording area on the non-removable recording medium, and the recording reservation information is registered in advance. Recording medium designation information for designating a detachable recording medium as a recording destination of a program, and the recording means is associated with a detachable recording medium designated by the recording medium designation information included in the recording reservation information. The designated program is recorded in a recording area, and the recording means designates a removable recording medium on which the designated program is to be recorded among the recording reservation information recorded in the reservation information recording unit. Recording reservation information including recording medium designation information, recording reservation information for designating the designated program is recorded, and the designated program is recorded on the non-removable recording medium. If you, it is preferable to record the designated program in the removable recording medium.

  According to the above configuration, the designated program is recorded in the recording area associated with the recording medium designation information, and the recorded designated program is specified as the removable recording medium designated by the recording medium designation information when recording the designated program. Only recorded against.

  Thus, in the first program recording apparatus according to the present invention, the designated program recorded on the non-removable recording medium is recorded only on the removable recording medium determined in advance when setting the recording reservation of the designated program. Will be. That is, in the program recording apparatus according to the present invention, there is an effect that it is possible to avoid that the designated program is recorded on a detachable recording medium in which recording of the designated program is not desired.

  In the program recording apparatus according to the present invention, when the recording reservation information for designating the designated program is not recorded on the removable recording medium, the erasing means sends the recording reservation information from the reservation information recording unit. It is preferable to erase.

  According to the above configuration, the recording reservation information recorded in the reservation information recording unit is not recorded on the removable recording medium with the recording reservation information that matches the recording reservation information recorded in the reservation information recording unit. If erased.

  This is because the designated program is already recorded on a removable recording medium in another program recording apparatus, and it is considered that the recording reservation information for designating the designated program is deleted from the removable recording medium. .

  Thus, in the first program recording apparatus according to the present invention, it is possible to avoid a process of recording a program already recorded on a removable recording medium on the removable recording medium. In other words, the first program recording apparatus according to the present invention has an effect of preventing the program that should have been deleted from being recorded again on a removable recording medium.

  In the program recording apparatus according to the present invention, recording reservation information for specifying the designated program is recorded, the designated program is not recorded on the non-removable recording medium, and the scheduled recording date and time of the designated program is recorded. Is a date and time that is past the current date and time, the erasing means preferably erases the recording reservation information from the reservation information recording unit.

  According to said structure, the recording reservation information currently recorded on the reservation information recording part is recorded on the recording medium which can attach or detach the recording reservation information which corresponds to the recording reservation information currently recorded on the reservation information recording part. Is deleted when the designated program designated by the recording reservation information is not recorded on a non-removable recording medium and the scheduled recording date and time of the designated program designated by the recording reservation information is a past date and time. .

  This is because it is considered that the recording of the designated program designated by the recording reservation information has failed in the program recording apparatus.

  Thereby, in the first program recording apparatus according to the present invention, it is possible to avoid re-determining whether or not the recording reservation information for which there is no program to be recorded is recorded on the removable recording medium. . That is, in the first program recording apparatus according to the present invention, it is possible to prevent an increase in time required for recording a program from a non-detachable recording medium to a removable recording medium from the next time.

  In the program recording apparatus according to the present invention, the erasing unit adds recording reservation information for specifying the designated program recorded on the removable recording medium by the recording unit to the reservation information recording unit, and It is preferable to erase from a removable recording medium.

  According to the above configuration, when the designated program is recorded on the removable recording medium, the recording reservation information for designating the designated program is deleted from the removable recording medium.

  Thus, in the first program recording apparatus according to the present invention, when the designated program is installed in another program recording apparatus, it is avoided that the designated program already recorded is recorded again. There is an effect that can.

  In addition, it is possible to avoid filling the area for recording the recording reservation information on the removable recording medium.

  The second program recording apparatus according to the present invention is the recording reservation information recorded in the reservation information recording unit, and the designated program specified by the recording reservation information including a plurality of date and time information for recording the program cannot be detached. Recording means for recording on a recording medium, and recording reservation information for specifying the specified program are recorded on a removable recording medium having recording information indicating the date and time when the program recorded based on the recording reservation information was last recorded. If the designated program is recorded on the non-removable recording medium and the recording execution date / time of the designated program is later than the date / time indicated by the recording information, the designated program is recorded on the removable recording medium. Recording means for recording on a medium; and update means for updating the recording information to recording information representing the date and time when the designated program was recorded.

  In the second program recording apparatus according to the present invention, the recording reservation information recorded in the reservation information recording unit is recorded on a detachable recording medium, and the designated program specified by the recording reservation information is not detachable. If it is recorded on the recording medium and the recording execution date / time of the designated program is later than the date / time indicated by the recording information, the designated program is recorded on the removable recording medium.

  As described above, in the second program recording apparatus according to the present invention, whether or not the recording reservation information recorded in the reservation information recording unit matches the recording reservation information recorded in the removable recording medium. And the program to be recorded on the removable recording medium is detected by determining whether or not the recording execution date and time of the designated program is later than the date and time indicated by the recording information.

  Here, it is determined whether or not the recording reservation information that matches the recording reservation information recorded in the reservation information recording unit is recorded on the removable recording medium, and the recording execution date and time of the designated program represents the recording information. The time required to determine whether or not it is later than the date and time is shorter than the time required to compare program data itself.

  Therefore, the second program recording apparatus according to the present invention has an effect of shortening the time required for recording the program recorded on the non-detachable recording medium on the removable recording medium.

  In the second program recording apparatus according to the present invention, the recording information recorded on the removable recording medium is updated to the date and time when the designated program was recorded. As a result, the second program recording apparatus according to the present invention also has an effect that it is possible to easily avoid re-recording of a program that has already been recorded on a removable recording medium.

  In the program recording apparatus according to the present invention, the detachable recording medium is a program that is recorded on a date and time before the recording information among programs recorded based on the recording reservation information. Recording information indicating a program that is not recorded from the non-removable recording medium is recorded, and the recording means stores the recording reservation information that specifies the recording required program specified by the recording required information. When the program to be recorded is recorded on the non-removable recording medium and recorded on the information recording unit, the program to be recorded is recorded on the removable recording medium, and the updating means includes the recording information In addition to the update, it is preferable to delete the required recording information specifying the recording required program.

  According to the above configuration, when the recording reservation information for specifying the required recording program represented by the required recording information is recorded in the reservation information recording unit, and the required recording program is recorded on the non-detachable recording medium Then, the required recording program is recorded on a removable recording medium.

  As described above, in the second program recording apparatus according to the present invention, recording reservation information for specifying the program is recorded in the reservation information recording section even if the recording is performed at a date and time before the recording information. Thus, by determining whether or not the required recording program is recorded on a non-detachable recording medium, the program is detected as a program to be recorded on the removable recording medium.
