With the spread of television broadcasts such as terrestrial broadcasts and satellite broadcasts, program recorders for recording and playing back broadcast programs of television broadcasts are widely used.

Most of the conventional program recording apparatuses record video signals and audio signals on a tape medium, etc., and when recording a program transmitted from a broadcasting station by broadcasting or the like, a program that a user intends to record is recorded. In response, the recording setting (for example, channel, recording time, standard mode / triple mode, etc.) was performed.

However, with the recent development of digital signal processing technology, a program recording apparatus for recording a broadcast program as a digital signal on a recording medium (recording medium) such as a hard disk or an optical disk has also appeared. In general, a program recording apparatus has a built-in timer device and has a recording reservation function for automatically recording a program by specifying a date and time in advance.

Here, in the above-described timer device, conventionally, the user himself / herself has to set the date and time when a desired broadcast program is broadcast to the timer device or the like. As a method for reducing such a burden on the user, for example, when the user selects broadcast program guide data (Electronic Program Guide) provided through the Internet or the like, the date / time data corresponding to the program recording apparatus is obtained. A method of automatically capturing and automatically setting the date / time data as a recording date / time is known. In addition, as an application of the method for automatically setting the recording date and time, the program recording apparatus includes a predicting unit that predicts the tendency of the program viewed by the user, so that it can be automatically set according to the tendency of the broadcast program viewed by the user. A method of executing recording reservation setting has been proposed.

Here, the optical disc described in Patent Document 1 is a recording start scheduled time and recording end of a preset specific type of television broadcast unique to the optical disc among a plurality of types of television broadcasts that can be recorded on the optical disc. Recording reservation information including at least the scheduled time is recorded. Since the recording reservation information corresponding to the television broadcast unique to each optical disc is recorded, the recording reservation information is read before recording the television broadcast, and the television to be recorded based on the read recording reservation information. By selecting and recording the John broadcast, it is possible to record only a television broadcast (for example, a continuous drama, etc.) unique to the optical disk in one optical disk.

In the DVD recording / reproducing apparatus described in Patent Document 2, in the recording reservation execution process, the controller reads the disk ID of the recording reservation setting contents, stores the disk ID in the storage unit, and matches the disk ID of the recording reservation setting contents. The disk ID of each disk stored in the stocker is sequentially read and stored until a disk is detected. When a disk with a matching disk ID is detected, the disk is extracted and recording is performed based on the reservation setting contents.

In the optical disc device described in Patent Document 3, when the weekly recording reservation is set only in the weekly recording reservation setting field on the setting screen, the back-end MCU executes weekly recording reservation as usual, while the setting screen If weekly recording reservation is set in the weekly recording reservation setting field and single recording reservation is set in the single recording reservation setting field, priority is given to that single recording reservation without canceling the weekly recording reservation. To record.

It is assumed that the recording reservation information is reservation information A, and the reservation information A is information indicated by “2009/1/1 12:00 to 13:00 channel A title AAA”.

Next, FIG. 29B is a diagram showing a state in which the disc is taken out from the device A and the disc is inserted into another recorded program reservation device B (hereinafter, device B). By this operation, the reservation information A recorded on the disc is copied to the device B, and as a result, the devices A and B can share the reservation information A. As described above, in the state shown in FIGS. 29A and 29B, the devices A and B can share the reservation information without any problem.

However, in the state shown in FIG. 29 (c), there is a contradiction in the sharing of reservation information. This will be specifically described.

FIG. 29 (c) shows a disc on which reservation information C (2009/1/1 12:00 to 13:00 channel C Ｃ title CCC) is recorded, reservation information B (2009/1/1 12:00 to 13: It is a figure which shows a mode that it inserts in the apparatus A with which 00 (channel B (title BBB)) was recorded.

In this case, the reservation information B and C are to record programs of different channels in the same time zone, and the device A cannot record two programs at the same time. Further, which reservation information of the reservation information B and C is positive varies depending on the use situation of the user. In addition, it is necessary to wait for an instruction from the user as to which of the reservation information B or the reservation C is prioritized.

As described above, when a plurality of program recording apparatuses exist in a system in which the recording reservation information is written in the program recording apparatus by inserting a plurality of discs on which the recording reservation information is recorded into the program recording apparatus, the usability Was significantly lower.

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 memory | storage part 340 is demonstrated referring FIG. 3 (a) and (b). 3A and 3B are diagrams illustrating an initialization process of the storage unit 340, and FIG. 3A is a diagram illustrating an example of display on the display device when the storage unit 340 is initialized. FIG. 7B is a diagram schematically illustrating 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.

Initialization processing is executed by receiving an initialization processing 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. 3B shows the storage unit 340 after the initialization process. As shown in FIG. 3B, 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. 3B, 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.

Management information for managing each of the areas 1 to n is recorded in the My Disk Management Area. In FIG. 3B, for convenience, an area in which management information for managing area 1 is recorded is referred to as “entry 1”. Similarly, an area in which management information for managing areas 2 to n is recorded is an entry. 2 to 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.

“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.

“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.

Also, as shown in FIG. 3B, “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 areas 1 to n may be used as a spare area.

<Optical disk registration process>
Next, an optical disk registration process for the storage unit 340 will be described with reference to FIGS. 4 (a) and 4 (b). 4A and 4B are diagrams showing an optical disc registration process, FIG. 4A is a diagram showing an example of display on the display device during the optical disc registration process, and FIG. 4B is an optical disc. It is the figure which showed typically the memory | storage part 340 after this registration process.

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

When the optical disc is loaded in the drive unit 300, the drive control unit 320 instructs the disc drive unit 330 to read the media ID of the optical disc from the loaded optical disc. 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 the 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. 4A on the display device.

FIG. 4B shows a 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 disc is recorded in entry 1, the optical disc 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 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, my disks associated with the areas 2 to n are referred to as “disks 2 to n”.

<Reserved video recording operation>
The content recording operation, content reproduction operation, content editing operation, and content copying operation in the recorder apparatus 100 that has been previously set will be described below.

The content recording operation in the recorder apparatus 100 will be described below with reference to FIGS. 5 (a) to (c) to FIGS. 14 (a) to (c). Here, the reservation recording process will be described as an example of the content recording operation.

The reservation recording process in the recorder apparatus 100 can be broadly 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 apparatus 100 will be described below with reference to FIGS. 5 (a) to 5 (c). FIGS. 5A to 5C are diagrams showing reservation registration processing in the recorder apparatus 100, and FIG. 5A is a diagram schematically showing the state of the storage unit 280 after the reservation registration processing. () Is a diagram schematically showing the state of the storage unit 340 and MyDisk 1 after the reservation registration process, and (c) is a diagram showing an example of display on the display device during the reservation registration process.

The reservation registration process is a process of 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, as shown in FIG. 5A, 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 target”. Includes "My Disk" information. Hereinafter, the recording target My Disc information will be described by taking the media ID of the loaded My Disc as an example, but other information may be used as long as the information can identify the My Disc. 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 the 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 (FIG. 5B). At this time, since the media ID is already recorded on the disc 1, it is not necessary to record the media ID.

Note that the user may be able to select the recording target MyDisk 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. 5C shows an example of an image displayed on the display device when a reservation is registered when the disc 1 associated with the area 1 of the storage unit 340 is loaded.

(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, FIG. This will be described below with reference to b). FIGS. 6A and 6B are diagrams showing a recording process in a state where the My Disk is loaded, and FIG. 6A schematically shows the state of the storage unit 340 and the My Disk 1 after the recording process. FIG. 4B is a diagram schematically illustrating the state of the storage unit 280 after the recording process.

When the recording of the content 1 is completed, as shown in FIG. 6B, 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. 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. 7 (a) to (c). FIGS. 7A to 7C are diagrams showing the states of the storage unit 340 and the storage unit 280 when the content 1 is recorded. FIG. 7A corresponds to the recording state of the content in the area 1 of the storage unit 340. FIG. 4B is a diagram showing a map table when content 1 is recorded, and FIG. 4C is a title management table when content 1 is recorded. FIG.

Here, generally, the data capacity 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 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. 7A shows a virtual disk image in the area 1 of the storage unit 340. As shown in FIG. 7A, in the area 1 of the storage unit 340, when content 1 (data capacity: XGB) is recorded with the physical address “0x000” as the head address, the content 1 is displayed on the virtual disk image. 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.

Subsequently, a map table for realizing the association between the physical address and the virtual address shown in FIG. 7A will be described with reference to FIG. 7B.

The map table is recorded as map information in the My Disk management area of the storage unit 340. As shown in FIG. 7B, the map table is recorded in association with a virtual disk map representing a map in a virtual disk image and a memory map representing a map in the area 1 of the storage unit 340 for each content. Yes. 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”.

The contents of the map table are updated as content 1 is recorded in area 1. FIG. 7B shows a map table when the area 1 of the storage unit 340 is in the state shown in FIG. As shown in FIG. 7B, 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. 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.

Note that the entry parameter in FIG. 7B 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 the area 1. It is an area.

Also, 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. A title management table recorded in a content management area in which information related to 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. 7 (c), for the title name indicating each content, the time required for reproducing the content, the reproduction quality of the content, the number of remaining dubbing times (up to 10), and 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.

FIG. 7C shows an example of the title management table when the map table shown in FIG. 7B is set. 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)
Subsequently, with respect to the recording process in the case where 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, FIGS. This will be described below with reference to b). FIGS. 8A and 8B are diagrams showing a recording process in a state where the my disk is not loaded in the recorder apparatus 100, and FIG. 8A schematically shows the state of the storage unit 340 after the recording process. FIG. 4B is a diagram schematically illustrating 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 sends a write command to the disk 1 from the back-end control unit 240 in 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 after being converted into a write command to 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.

When the recording of the content 2 is completed, as shown in FIG. 8B, the back-end control unit 240 deletes the reservation information indicating the reservation recording of the content 2 from the reservation information management area in the storage unit 280.

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. 9 (a) to 9 (c). FIGS. 9A to 9C are diagrams showing the states of the storage unit 340 and the storage unit 280 when the content 2 is recorded. FIG. 9A corresponds to the recording state of the content in the area 1 of the storage unit 340. FIG. 5B is a diagram showing a map table when content 2 is recorded, and FIG. 5C is a title management table when content 2 is recorded. FIG.

As shown in FIG. 9A, since the 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, the content 2 (data capacity: XGB) is The content address 1 is recorded after 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. 9B 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. 9B, in addition to the map table shown in FIG. 7B, “0x250” is set as the start address in the virtual disk map in the content 2, XGB is set as the data size, and the memory “0x200” is set as the head address in the 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. 9C shows an example of the title management table when the map table shown in FIG. 9B is set. As shown in FIG. 9C, in the title management table, in addition to the title management information of the title 1 indicating the content 1 shown in FIG. 7C, the title management information of the title 2 indicating the content 2 is 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, FIGS. 10 to 12 (a) to (c) are shown for the synchronization processing for recording the content recorded in the storage unit 340 but not recorded on the My Disc on the My Disc. This will be described below with reference.

When the disc 1 is loaded in the drive unit 300, the drive control unit 320 refers to the map table of the entry 1 and determines whether there is content whose synchronization flag is “0”. For example, when there is content 2 whose synchronization flag is “0”, the drive control unit 320 records the content 2 recorded in the area 1 of the storage unit 340 on the disc 1 so as to record (write out) the content 2 on the disc 1. The unit 330 is instructed. The disc drive unit 330 writes the content 2 recorded in the area 1 of the storage unit 340 to the disc 1 in response to an instruction from the drive control unit 320. As a result, the contents 1 and 2 recorded in the area 1 of the storage unit 340 are both recorded on the disc 1 (FIG. 10). That is, the content 2 is in a synchronized state.

When the writing of the content 2 to the disc 1 is completed, the drive control unit 320 notifies the back-end unit 200 that the content 2 synchronization processing 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.

In addition, when the writing of the content 2 to 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 content 2 recorded on the disc 1. 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. 10). FIG. 10 is a diagram showing the state of the storage unit 340 and the disc 1 after the content synchronization processing.

Next, the state of the storage unit 340 and the storage unit 280 when the content 2 recorded in the area 1 of the storage unit 340 is written to the disc 1 will be described below with reference to FIGS. 11 (a) to 11 (c). To do. 11A to 11C 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 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 synchronizing the content 2, (c) is a figure at the time of synchronizing the content 2 It is a figure which shows a title management table.

As shown in FIG. 11A, 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. 11B, the synchronization flag of the map table recorded in the map information of the entry 1 indicates “1” indicating that the content is recorded on the My Disk. " Further, as shown in FIG. 11C, 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” and the synchronization state is Changed to information indicating synchronization.

Next, the synchronization processing of content 2 when content (content 3) having “0x250” as the head address has already been recorded on disc 1 will be described below with reference to FIGS. 12 (a) to 12 (d). To do.

12A to 12D are diagrams showing the states of the storage unit 340 and the storage unit 280 when the content 2 is synchronously processed. FIG. 12A shows the start address of the content 2 in the virtual disk image. Is a diagram showing a state where the content 3 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) is a content 2 is a diagram illustrating a map table when 2 is synchronized, and FIG. 3D is a diagram illustrating a title management table when content 2 is synchronized.

As shown in FIG. 12A, when the content 3 having the head address “0x250”, which is the head address of the content 2 in the virtual disk image, is already recorded on the disk 1, the address “0x250” of the disk 1 is set. The content 2 cannot be recorded on the disc 1 as the head 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 area 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. 12D, 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 changed. The associated information (reproduction time and reproduction image quality) 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. 13 is a diagram showing a state of the storage unit 340 and the disc 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. 13, the content 4 is also recorded on the disc 1 for recording in a state where the My Disc is loaded.

14A to 13C regarding the state shown in FIG. 13, that is, the state of storage unit 340 and storage unit 280 when content 4 is recorded in region 1 after content 1 and content 2 have been deleted from region 1 However, it will be described below. FIGS. 14A to 14C are diagrams showing the states of the storage unit 340 and the storage unit 280 when the content 4 is recorded. FIG. 14A corresponds to the recording state of the content in the area 1 of the storage unit 340. FIG. 5B is a diagram showing a map table when content 4 is recorded, and FIG. 5C is a title management table when content 4 is recorded. FIG.

When the content 1 and the content 2 are deleted from the area 1, the drive control unit 320 deletes the 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. 14A, the contents 1 and 2 remain on the virtual disk image without being erased. That is, as shown in FIG. 14B, even if the contents 1 and 2 are deleted from the area 1, the information of the contents 1 and 2 is not deleted from the virtual disk map in the map table. become.

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. 14C, 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 playback process is a process executed in response to a content playback 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. 15 and 16. FIG. 15 is a diagram showing the states 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. 16 is a diagram schematically showing a medium from which content is read during reproduction when a My Disc is loaded.

As shown in FIG. 15, the disc 300 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. 15, 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 to read 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 playback process when no My Disk is loaded will be described below with reference to FIGS. FIG. 17 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. 18 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. 17, content 1 and content 2 are recorded in area 1 of storage unit 340. However, unlike the case of FIG. 15, the disc 300 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. 17, the details of the title management table are omitted as in FIG.

In the state shown in FIG. 17, among the contents 1 to 3 represented by the titles 1 to 3 recognized by 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. 18, 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.

Note that the content 1 read processing shown in FIG. 18 is the same as the content 1 read processing in the case where the My Disc is loaded, and thus the description thereof is omitted here.

<Content editing operation>
Next, content editing operations in the recorder apparatus 100 will be described below with reference to FIGS. 19 and 20A and 20B.

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.

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, similarly to the content playback process. 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)
Editing processing in the case where a my disk is loaded will be described below with reference to FIGS. 15 and 19. FIG. 19 is a diagram schematically showing a medium on which content is edited when a My Disc is loaded.

As shown in FIG. 15, the disc 300 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 records information on 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. 15, 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 a command 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 content data 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. 17 and 20A and 20B. FIGS. 20A and 20B are diagrams schematically showing a medium on which content is edited when the My Disc is not loaded, and FIG. 20A is a diagram when the Disc 1 is not loaded. The medium to be edited is shown, and (b) shows the reflection of the changed portion on the disk 1 when the disk 1 is loaded.

In the state shown in FIG. 17, among the contents 1 to 3 represented by the titles 1 to 3 recognized by 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. 20B, 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 on the disc 1 in the area 1. Reflected on content 2. At this time, the map table recorded in entry 1 is also updated.

<Content copy operation>
Next, a content copying operation in the recorder apparatus 100 will be described below with reference to FIGS. 21 (a) and 21 (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. FIGS. 21A and 21B are diagrams illustrating the in-memory copy process in the recorder apparatus 100, and FIG. 21A is a diagram illustrating the state of the storage unit 340 after the in-memory copy process. FIG. 10 is a diagram illustrating a state of a 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. 21B, 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”. Become.

As shown in FIG. 21A, 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.

In addition, the back-end control unit 240 that has received an 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 optical disk file system will be described below with reference to FIGS. 22 (a) to 22 (c). 22A to 22C are diagrams showing data management using a file system. FIG. 22A shows an example of a file system recorded in the storage unit 280. FIG. FIG. 6C shows a map table for each file, showing the correspondence relationship of the recording state of the disc 1 corresponding to the recording state of the content.

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 disc in order to specify the address of the optical disc 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-off or the like, the acquired file system is also stored in the storage unit 280 (FIG. 22A). 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.).

FIG. 22A shows only the file system related to the disk 1, but the file system management area of the storage unit 280 stores as many file systems as the number of disks registered as my disks. Yes.

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 FIGS. 22B and 22C, 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 stores the information. By referring to the arrangement information of the content 1 in the file system recorded in the 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 this embodiment, but more precisely, as shown in FIG. The arrangement information for each is shown.

Also, when deregistering My Disk, the file system recorded in the file system management area is also deleted along 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. 23 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 the title list via the operation input unit, the display apparatus 500 displays the title list and the content as shown in FIG.

That is, as shown in FIG. 23, the display screen of the display device 500 is divided into 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.

In the title list display section 520, as shown in FIG. 23, tabs corresponding to registered My Disks are displayed. 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. 23 shows a title list when the disc 1 tab 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.

(Description of operation of recorder device 100)
The configuration of the recorder device 100 and the outline of the operation of the recorder device 100 have been described above. Next, with reference to FIGS. 1, 24, and 25, a more detailed configuration, operation, and the like of the recorder device 100 according to the present embodiment will be described.

First, specific examples of various operations performed by the recorder device 100 will be described with reference to FIG. 24 for easy understanding. Next, the configuration of the recorder device 100 will be described with reference to FIG.

(Specific operation of recorder device 100)
The outline of FIG. 24 will be described below. FIG. 24 is a diagram for explaining a specific operation of the recorder apparatus 100. For convenience of explanation, it is assumed that there are two recorder devices 100 (recorder device A and recorder device B).

FIG. 24A is a diagram showing a state before the optical disc is inserted into the recorder device A. FIG. At this stage, the recorder apparatus A does not permit the user to update / set recording reservation information, which is information for making a recording reservation for the content (program). Therefore, the user cannot input the recording reservation information to the recorder device A at the stage shown in FIG.

FIG. 24B is a diagram showing a state in which the optical disk is inserted into the recorder apparatus A. The user is permitted to set recording reservation information at this stage. Therefore, in FIG. 24B, the user sets recording reservation information (reservation information A) in the recorder apparatus A. The reservation information A is recorded on the optical disc from an operation input unit provided inside or outside the recorder device A. At this time, since the reservation information A is written on the optical disc, the recorder device A and the optical disc share the reservation information A.

FIG. 24C is a diagram showing a state after the optical disc is taken out from the recorder device A. At this stage, the recorder apparatus A does not permit the user to set the recording reservation information. Accordingly, at the stage of FIG. 24C, the user cannot input new recording reservation information to the recorder device A.

FIG. 24 (d) is a diagram showing a state in which an optical disc has been inserted into the recorder apparatus B. The recorder device B recognizes the reservation information A recorded on the optical disc as the latest recording reservation information. The reservation information A is read by the recorder device B and shared between the optical disc and the recorder device B.

FIG. 24 (e) is a diagram showing a state in which new reservation information B is set by the user adding, changing, and deleting the recording reservation information with respect to the reservation information A in the recorder apparatus B. The recorder device B permits the user to update the recording reservation information by inserting an optical disk into the recorder device B. Therefore, after the optical disk is inserted into the recorder apparatus B, the user adds, changes, and deletes the recording reservation information with respect to the reservation information A, and sets new reservation information B. The reservation information B is recorded on the optical disc from an operation input unit provided inside or outside the recorder device B.

FIG. 24 (f) is a diagram showing a state after the optical disk is taken out from the recorder device B. At this stage, the recorder apparatus B does not permit the user to set the recording reservation information. As shown in the figure, reservation information A is recorded on the recorder device A, and reservation information B is recorded on the recorder device B and the optical disc.

FIG. 24 (g) is a diagram showing a state in which an optical disk is inserted into the recorder apparatus A. FIG. The recorder device A recognizes the reservation information B recorded on the optical disc as the latest recording reservation information. Then, the reservation information B is read by the recorder device A. As a result, the reservation information B is shared between the optical disc and the recorder device A and between the recorder device B at the stage of FIG.

As described above, as shown in FIGS. 24A to 24G, the recorder apparatuses A and B acquire the recording reservation information (reservation information A and B) from the optical disk, and the optical disk is inserted into the recorder apparatuses A and B. In this case, the reservation information A / B is updated, and the user is allowed to update the recording reservation information for making a recording reservation in the recorder apparatus A / B.

(Description of essential parts of recorder device 100)
Next, a more detailed configuration of the recorder device 100 will be described with reference to FIG. The description of the same contents as those described with reference to FIGS. 2 to 23 is omitted.

FIG. 1 is a block diagram showing a main configuration of the drive unit 300 of the recorder apparatus 100. As shown in FIG. As illustrated, the drive unit 300 includes a permission unit 350 and a warning unit 360 (warning unit) in addition to the interface unit 310, the drive control unit 320, the disk drive unit 330, and the storage unit 340. The interface unit 310, the drive control unit 320, the disk drive unit 330, the storage unit 340, the permission unit 350, and the warning unit 360 are connected to each other via a bus line.

The permission unit 350 updates the recording reservation information acquired from the optical disk by the disk drive unit 330 when the optical disk is inserted into the recorder device 100, and records the recording reservation information that is information for making a recording reservation in the recorder device 100. Allow users to update.

If the permission unit 350 realizes an operation of not permitting (not accepting) an input from the input operation unit by the user when no optical disk is inserted in the recorder device 100, the drive control of the drive unit 300 is performed. Unit 320 or back end control unit 240 of back end unit 200, or may be provided separately from back end control unit 240 and drive control unit 320, or may be selected as appropriate. Therefore, the configuration of FIG. 1 is merely an example.

Further, whether or not the optical disk has been inserted into the recorder apparatus 100 is determined by receiving a signal indicating whether or not the disk drive unit 330 has recognized the optical disk, and even if the permission unit 350 determines by itself, the drive control of the drive unit 300 It may be determined by the unit 320, or may be determined by the back-end control unit 240 of the back-end unit 200, and may be selected as appropriate.

Furthermore, the recording reservation information in the optical disc and the recorder device 100 only needs to include at least information relating to the recording channel, time, and image quality.

When the permission unit 350 grants the above permission, the user updates the recording reservation information acquired from the optical disk by the disk drive unit 330 by the input operation from the operation input unit, and the recording for recording reservation by the recorder device 100 is performed. It is possible to set reservation information.

Note that the details of the recording reservation may be performed in accordance with the reservation registration process described with reference to FIG. 5, and the description thereof is omitted here.

The warning unit 360 warns the user that the recording reservation information acquired from the optical disk by the disk drive unit 330 cannot be updated when the optical disk is not inserted.

As the warning method, for example, a user operation menu used for updating the recording reservation information is displayed on the TV screen connected to the recorder apparatus 100 to notify that the recording reservation information cannot be updated or by voice. The method of not displaying on a screen etc. can be considered. Or, although the user operation menu is displayed, the menu for adding / changing / deleting recording reservation information is grayed out so that those menus can not be selected, and in addition, a message “whether a disc has been inserted” is grayed out and cannot be selected. It is also possible to display such as “No”.

If the warning unit 360 warns the user that the recording reservation information acquired from the optical disk cannot be updated by the disk drive unit 330 when no optical disk is inserted in the recorder device 100, the drive unit May be provided in the drive control unit 320 of the unit 300 or the back-end control unit 240 of the back-end unit 200, or may be provided separately from the back-end control unit 240 and the drive control unit 320, and is appropriately selected. You can do it. Accordingly, the configuration of FIG. 1 is merely an example.

Next, the recording reservation information setting operation related to the recorder apparatus 100 will be described with reference to FIG. FIG. 25 is a flowchart for explaining the operation of setting recording reservation information according to the recorder apparatus 100, and the flow will be explained according to the operations shown in FIGS. 24 (a) to 24 (g).

First, in step S10, the optical disc is inserted into the recorder device A (recorder A in the drawing). At this time, it is assumed that the recording reservation information is not set in the recorder device A and the optical disc.

It should be noted that since the disc drive unit 330 has not recognized the optical disc before the optical disc is inserted into the recorder device A, a signal indicating that is transmitted to the permission unit 350. Alternatively, the permission unit 350 may determine that the disk drive unit 330 has not recognized the optical disk in response to a signal not being transmitted from the disk drive unit 330 to the permission unit 350. As a result, since the permission unit 350 does not permit the input operation, the user cannot set the recording reservation information in the recorder apparatus A.

Further, at a time point before the optical disc is inserted into the recorder device A, the warning unit 360 may display a message such as “No disc is inserted” on the TV screen connected to the recorder device A.

Next, in step S12, the reservation information A is set in the recorder device A. This is because when the optical disk is inserted into the recorder apparatus A, the permission unit 350 permits the user to set recording reservation information, which is information for making a recording reservation in the recorder apparatus A. The user only needs to input the reservation information A from the input operation unit, and the reservation information A is recorded in the reservation information management area of the storage unit 280.

Subsequently, in step S14, the recorder device A and the optical disc share the reservation information A. This is because the disk drive unit 330 receives the instruction from the drive control unit 320 and records the recording reservation information set by the user in a predetermined area (reservation information management area) of the optical disk.

In step S16, the optical disk is taken out from the recorder device A. As a result, the recording reservation information cannot be set in the recorder device A for the above reason. That is, an input operation from the input operation unit cannot be accepted.

In step S18, the optical disk is inserted into the recorder apparatus B (recorder B in the drawing). Since the optical disk has not been inserted into the recorder apparatus B until this point, no recording reservation information is set in the recorder apparatus B.

Next, in step S20, the recorder apparatus B and the optical disc share the reservation information A. This is because the disc drive unit 330 related to the recorder device B is driven based on an instruction from the drive control unit 320 related to the recorder device B, reads the reservation information A from the loaded optical disc, and the reservation information A is recorded on the recorder. This is based on the result recorded in the reservation information management area of the storage unit 280 of the device B. At this point, the recorder apparatuses A and B and the optical disc share the reservation information A.

Subsequently, in step S22, the reservation information B is set in the recorder device B. This is because when the optical disk is inserted into the recorder apparatus B, the permission section 350 associated with the recorder apparatus B permits the update of the recording reservation information, which is information for making a recording reservation in the recorder apparatus B. The user only has to input the reservation information B from the input operation unit, and the reservation information B is recorded in the reservation information management area of the storage unit 280 associated with the recorder device B.

Note that the reservation information B is obtained by updating the recording reservation information such as addition, change, deletion, or no change of information for making a reservation for recording a program with respect to the reservation information A. Therefore, the reservation information B is newer recording reservation information than the reservation information A. The reservation information B may be input by a method in which the reservation information A is displayed on the television screen to which the recorder device B is connected and the reservation information A is changed.

In step S24, the recorder apparatus B and the optical disc share the reservation information B. This is because the disc drive unit 330 of the recorder device B receives the instruction from the drive control unit 320 of the recorder device B and records the reservation information B set by the user in a predetermined area (reservation information management area) of the optical disc. It depends.

In step S26, the optical disk is taken out from the recorder device B. As a result, the recording reservation information cannot be set in the recorder device B for the reason described above.

Subsequently, in step S28, the optical disk is inserted into the recorder device A. At this time, since the optical disc has not been inserted, the reservation information A is still recorded on the recorder device A. On the other hand, reservation information B is recorded on the optical disc.

In step S30, the recorder device A and the optical disc share the reservation information B. This is because the disk drive unit 330 of the recorder apparatus A is driven based on an instruction from the drive control unit 320 of the recorder apparatus A, reads the reservation information B from the mounted optical disk, and stores the reservation information B in the storage unit 340. According to the results recorded in At this point, the recorder apparatuses A and B and the optical disc share the reservation information B.

As described above, with regard to the recorder device B, in the recorder device B, when the optical disk is inserted into the own device, the permission unit 350 permits the update of the reservation information A acquired by the disk drive unit 330 and The reservation information B, which is information for making a recording reservation in the apparatus, can be set.

That is, the reservation information B is not set unless the optical disc is inserted into the recorder device B. That is, when the optical disk is taken out from the own apparatus, the recording reservation information is not changed until the optical disk is inserted again. When the optical disc is reinserted, the permission unit 350 permits the user to update the reservation information A and set the reservation information B. As a result, the recorder device B records a program based on the reservation information B. Although the recorder apparatus B has been described here, the same applies to the recorder apparatus A.

Thus, in the recorder apparatuses A and B according to the present embodiment, the optical disc is used as a physical key for setting recording reservation information on the recorder apparatus side. Then, when the optical disc is inserted into the recorder device A or B, setting of new recording reservation information is permitted by the permission unit 350 using the recording reservation information recorded on the optical disc as master information.

Next, effects obtained by the recorder device 100 will be described.

According to the above configuration, in the recorder device 100, when the optical disc is inserted into the recording device 100, the permission unit 350 permits the update of the recording reservation information acquired by the disk drive unit 330 from the optical disk. Recording reservation information for making a recording reservation in the apparatus is set.

Therefore, new recording reservation information is not set unless the optical disc is inserted into the own apparatus. That is, when the optical disk is removed from the own apparatus, the recording reservation information is not updated in the own apparatus until the optical disk is inserted again. When the optical disk is reinserted, the permission unit 350 permits the update of the recording reservation information acquired from the optical disk, and the user can set new recording reservation information. As a result, the recorder device 100 can record a program based on the set recording reservation information.

Therefore, the recording reservation information set in the recorder apparatus 100 is an update of the recording reservation information recorded on the optical disc, and can reflect the user's intention more reliably. Therefore, the updated scheduled recording information can be handled as scheduled recording information that should be prioritized over the scheduled recording information recorded on the optical disc. For this reason, the recorder apparatus 100 can solve the conventional problem that the recording reservation information in the recorder apparatus 100 and the optical disc are different and it cannot be determined which recording reservation information is preferentially handled.

Furthermore, the recorder device 100 includes a disk drive unit 330 that writes the updated recording reservation information to the optical disc, and the updated recording reservation information is also recorded on the optical disc. Therefore, it is possible to synchronize the recording reservation information recorded on the recorder device 100 and the optical disc, and to avoid a situation in which the recording reservation information contradicts between them. In addition, it is possible to share the recording reservation information via the optical disc among a plurality of recorder devices.

Therefore, in a system in which recording reservation information is shared among a plurality of recorder apparatuses via an optical disk, the recorder apparatus 100 uses the optical disk as a physical key for setting recording reservation information in the own apparatus. Then, when the optical disk is loaded in the own apparatus, the recording reservation information is permitted to be updated using the recording reservation information recorded on the optical disk as master information.

As a result, the recorder device 100 can record a program based on the recording reservation information newly set by the own device, and the user selects which of the recording reservation information on the optical disc side or the recorder device side has priority. Therefore, it is possible to realize a recorder device and a recording reservation information setting method that are excellent in usability and that do not need to be performed.

Also, in the recorder apparatus 100, the update of the recording reservation information acquired from the optical disc includes at least one of addition, change, deletion, and no change of information for making a reservation for recording a program.

In the recorder apparatus 100, when the optical disk is inserted into the own apparatus, the permission unit 350 permits the recording reservation information on the optical disk side acquired by the disk drive section 330 to be updated, and information for making a recording reservation in the own apparatus. The new recording reservation information is set.

That is, after the disk drive unit 330 acquires the recording reservation information on the optical disk side, the user adds, changes, or deletes information for recording recording of the program to the recording reservation information on the optical disk side, or The new recording reservation information is set without changing the recording reservation information on the optical disc side.

Therefore, after the recording reservation information acquired from the optical disc is subjected to “update” of addition, change, deletion, or no change of information for making a recording reservation for the program, the recorder device 100 performs the updated recording reservation. A program can be recorded based on the information.

Furthermore, the recorder device 100 includes a warning unit 360 that warns the user that the recording reservation information cannot be updated when the optical disk is not inserted.

In the recorder apparatus 100, the warning unit 360 warns that no optical disk is inserted, so that the user can recognize that the recording reservation information cannot be updated. As a result, the user is warned of the reason why the recording reservation information cannot be updated, and the user can use the warning as an opportunity to insert the optical disc when updating the recording reservation information.

Thus, the recorder device 100 can record a program based on the updated recording reservation information, and requires the user to select which recording reservation information on the optical disc side or the recorder device side has priority. do not do. Therefore, in a system for sharing recording reservation information among an plurality of recorder devices via an optical disc, a recorder device that is excellent in usability and can realize unification of recording reservation information, and a recording reservation information setting method Can be provided to the user.

[Embodiment 2]
Next, a recorder device 150 according to another embodiment will be described with reference to FIGS. The description of the same contents as those described with reference to FIG.
