Background art

In the DVD-Video (DVD video) standard, when video information compressed and encoded by MPEG (Moving Picture Expert Group) 1 or MPEG2, which is an example of a compression encoding method, is recorded on an optical disc such as a DVD. It is a standard that conforms to According to the DVD-Video standard, compression data and high-density recording of recorded data have been advanced to the extent that content information of about one movie can be recorded on one optical disk. The DVD-Video standard is mainly defined for the purpose of creating package software containing movies and other titles and selling the package software to users. On the other hand, according to the DVD-Video standard, it is mainly set for recording a read-only title, and thus free editing by the user is restricted. In particular, it is not suitable for recording titles of TV programs or the like in which CMs and the main part are discretely arranged while editing user-powered CMs. In addition, in the DVD-Video standard, it is not possible to record a copy-once title that is broadcast via digital terrestrial broadcasting or BS digital broadcasting.

[0003] Therefore, apart from the DVD-Video standard, the DVD-VR (Video Recording) standard shown in Patent Document 1 is defined. In the DVD-VR standard, for example, titles of TV programs and the like that are discretely arranged in CM and the main part can be recorded while editing user-powered SCM, or can be edited after recording. In addition, the DVD-VR standard supports CPRM (Contents Production for Recordable Media) and so on, so it can record copy-once titles. For this reason, the copyright of the recorded title can be suitably protected.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, as the best mode for carrying out the invention, description will be given on embodiments of the information recording medium, the information recording apparatus and method, and the computer program of the present invention.

(Embodiment of Information Recording Medium)

The embodiment of the information recording medium of the present invention includes a first area in which first data compliant with a DVD—Video—DC (DVD—Video Download Contents) method, which is a method for downloading predetermined content, is recorded. The DVD-Video-TS (DVD-Video Title Set) system, which is different from the DVD-Video-DC system, is used to perform the playback operation of the information playback apparatus that cannot recognize the first data. A second area in which second data including command data is recorded.

[0017] According to the embodiment of the information recording medium of the present invention, the first data compliant with the DVD-Video-DC system (for example, various data in the Video-DC folder described later, (New format data) Power Recorded in the first area (for example, the area where the Video—DC folder described later is recorded).

In the present embodiment, in particular, in addition to the first data, second data compliant with the DVD-Video-TS system (for example, various data in the Video-TS folder described later, which is data of the old system) ) Force Recorded in the second area (for example, the area where the Video-TS folder described later is recorded). The second data includes at least stop command data. The stop command data is command data for stopping the reproduction operation of the information reproducing apparatus. When the stop command data is read and reproduced or executed by the information reproducing apparatus, the subsequent reproducing operation of the information reproducing apparatus is stopped.

Thereby, for example, an information reproducing apparatus capable of recognizing the first data compliant with the DVD-Video-DC system suitably reads the first data recorded in the first area. Can be played or executed. On the other hand, the first data that conforms to the DVD—Video—DC format cannot be recognized. 方式 Old-style information playback device (in other words, only the second data that conforms to the DVD—Video—TS format can be recognized. An old-fashioned information reproducing device that can read data cannot read the first data recorded in the first area, but can read the second data recorded in the second area. For this reason, in the old information reproducing apparatus, the reproducing operation of the information reproducing apparatus is stopped by reproducing or executing the stop command data. Therefore, even when the information recording medium according to the present embodiment is loaded on the old information reproducing apparatus, there is no possibility that an unintended operation in the information reproducing apparatus will occur. That is, the operation of the old information reproducing apparatus can be terminated in a suitable manner.

[0020] As described above, according to the embodiment of the information recording medium of the present invention, when new method data is recorded, the new method data can be recognized. The operation of the non-information reproducing apparatus can be suitably terminated.

In this embodiment, the first area in which the first data is recorded and the second area in which the second data is recorded may be physically distinguished. For example, the first area is arranged on the relatively inner circumference side of the information recording medium (that is, the first data is recorded), and the second area is arranged on the relatively outer circumference side of the information recording medium (that is, the first data is recorded). Second data is recorded) You may comprise as follows. Alternatively, the first area is arranged on the relatively outer circumference side of the information recording medium (that is, the first data is recorded), and the second area is arranged on the relatively inner circumference side of the information recording medium (that is, the first data is recorded). The second data is recorded). Alternatively, the first area in which the first data is recorded and the second area in which the second data is recorded may be physically distinguished. For example, the first data and the second data are recorded at a common physical position, but the information reproducing apparatus or the like can logically distinguish the first data and the second data from each other. May be recorded!

In addition, in the present embodiment, the term “Video—DC system (N! /, Or Video—DC directory)” is used. It is intended to indicate a newly proposed method for the conventional method (or guideline or format) called “TS method (or Video-TS directory)”. The “Video_DC system (or Video-DC directory)” is, for example, storing content that complies with the DVD-Video standard and encrypted by CPRM or the like on a server, and stores the content according to user requirements. It is used when delivering the content to a user via a network. In other words, “Video-DC system (or Video-DC directory)” is performed using “Video-TS system (Na! /, Or Video-TS directory)” which is the traditional system. It is a new method that can be used when performing powerful operations. Of course, “Video-TS system (or Video-TS directory)” content may be distributed to users via the network, but this is a mode of distributing content that conforms to the conventional system. Therefore, it is different from the content distribution by “Video-DC system (or Video-DC directory)”. In this way, the “Video-DC system (or Video-DC directory)” is intended to indicate a new system different from the conventional “Video-TS system (or Video-TS directory)”. The wording may be specified arbitrarily. In other words, even if the phrase “Video-DC system (or Video-DC directory)” changes, it goes without saying that the information recording medium after the change is included in the scope of this embodiment. . Of course, the same applies to the embodiments described later.

For this reason, the reproduction operation of the information reproducing apparatus can be reliably stopped. Furthermore, even if the second data is recorded on the information recording medium in addition to the first data, it is not necessary to include unnecessary data in the second data, so the recording capacity for recording the first data is increased. You can also enjoy the effect of almost no decrease.

[0025] In another aspect of the embodiment of the information recording medium of the present invention, the second data further includes sequence data (for example, PGC described later) that defines a reproduction sequence of the second data. The sequence data defines the stop command data as data to be reproduced first (for example, as data to be reproduced first by a first play PGC described later! /).

[0026] According to this aspect, when reproducing the second data, the stop command data is reproduced or executed first. For this reason, the reproduction operation of the information reproducing apparatus can be reliably stopped. Furthermore, even if the second data is recorded on the information recording medium in addition to the first data, it is not necessary to include unnecessary data in the second data, so the recording capacity for recording the first data is increased. You can also enjoy the effect of almost no decrease.

In another aspect of the embodiment of the information recording medium of the present invention, the stop command data is

, Cell command data (for example, a cell command described later).

[0034] According to this aspect, the reproduction operation of the information reproducing apparatus described above is stopped by reproducing the title data. That is, it is possible to enjoy the various effects described above while suitably following the standard of the information recording medium.

[0035] As described above, in the aspect of the information recording medium in which the second data is included in the title data, the management data includes menu data for displaying a menu related to the title data, and the second data is The menu data may be included.

With this configuration, even when the display of the user power menu is instructed after the reproduction of the title data, the reproduction operation of the information reproduction apparatus described above is stopped by the second data included in the menu data. Therefore, the operation of the old information reproducing apparatus can be terminated in a suitable manner.

[0037] In the mode of the information recording medium in which the second data is included in the title data as described above, the management data defines a menu relating to the title data, and the title data is added to the title data after an instruction to display the menu is given. It can be configured to include menu data to skip the playback destination! /!

[0038] With this configuration, even if the display of the user power menu is instructed after playback of the title data, the playback destination is skipped to the title data by the menu data, and thus the playback operation of the information playback device described above is performed. A stop is made. Therefore, the operation of the old information reproducing apparatus can be terminated in a suitable manner.

Here, FIG. 1 (a) is a schematic plan view showing one basic structure of the optical disk according to the present embodiment, and FIG. 1 (b) is a schematic cross-sectional view of the optical disk and the correspondence to this. FIG. 2 is a schematic conceptual view of a recording area structure in the radial direction.

[0057] As shown in FIGS. 1 (a) and 1 (b), the optical disc 10 according to the present embodiment has, for example, a center hole 11 on a recording surface on a disc body having a diameter of about 12 cm, as in DVD. A lead-in area 12, a data area 15, and a lead-out area 18 are provided. The optical disc 10 has a recording layer and the like laminated on a transparent substrate 13. In each recording area of the recording layer, for example, tracks such as a groove track and a land track are alternately provided in a spiral shape or a concentric shape around the center hole 11. On this track, data is divided and recorded in units of ECC blocks. An ECC block is a data management unit that enables error correction of data.

Note that the optical disc 10 according to the present embodiment is not limited to an optical disc having a single recording layer as shown in FIGS. 1 (a) and 1 (b), and is an optical disc having a plurality of recording layers. May be

[0059] (2) Data structure on information recording medium

Next, a logical data structure (in other words, a file structure) of content recorded on the optical disc 10 will be described with reference to FIGS. FIG. 2 is a data structure diagram conceptually showing the basic data structure of the content recorded on the optical disc 10, and FIG. 3 shows the data structure of the content recorded on the optical disc 10. FIG. 4 is a data structure diagram conceptually showing the data structure of VTS30, and FIG. 4 is a data structure diagram conceptually showing the data structure of VMG50 in the data structure of contents recorded on optical disc 10, and FIG. FIG. 6 is a timing chart conceptually showing a PGC (Program Chain) that defines a playback unit of content recorded on the optical disc 10, and FIG. 6 is a plan view showing a warning text displayed by a warning text display cell. It is.

[0060] In the following description, a specific example in which the optical disc 10 conforms to the DVD standard will be described. Light up. Therefore, the detailed description of the configuration similar to the DVD standard is omitted for the sake of simplicity. Further, the content recorded on the optical disc 10 is preferably compressed in accordance with, for example, the MPEG (Moving Picture Expert group) system.

As shown in FIG. 2, the content recorded on the optical disc 10 includes n (where n is an integer of 1 or more and 99 or less) VTS (Video Title Set) 30 and 1 VMG ( Video Manager) 50 including Video— DC directory 21 (an example of “first data” in the present invention), one VTS30, one VTS30 and one VMG50 Video— TS directory 2 2 (A specific example of “second data” in the present invention) is included under the root directory.

[0062] It should be noted that the VTS 30 is, for example, a movie or a television program and related to it.

This is a set (collection) of titles (ie, the number of audio information and sub-picture information contained therein, the attributes such as specifications, supported languages, etc. are the same). The VMG50 also has information for managing the VTS30 included in the content together with the VMG50 (for example, data, data list, data file or data table, or a menu related to the entire VTS30 managed by the VMG50 (hereinafter referred to as “general menu”). ")"). Specifically, the VMG50 included in the Video—DC directory 21 is information for managing the VTS 30 included in the Video—DC directory 21, and the VM G50 included in the Video—TS directory 22 is the Video—TS directory. 22 is information for managing VTS30 included in

[0063] In addition, as will be described later, the Video-DC directory 21 is a so-called new recording in which content is recorded when content compliant with the DVD-Video standard is downloaded from Sano and recorded on the optical disc 10. This is the method directory. On the other hand, the Video_TS directory 22 is a so-called old-type directory in which content as package software authored by an author, for example, is recorded. However, in this embodiment, the Video—TS directory 22 does not record substantial contents (that is, movies, etc.), and recognizes the Video—DC directory 21 as will be described in detail later. To the information reproducing apparatus that cannot recognize the Video-TS directory 22, a warning message indicating that the optical disk 10 cannot be reproduced is displayed and the reproducing operation is stopped. Data for recording is recorded.

[0064] The data structures of the VTS 30 included in the Video-DC directory 21 and the VTS 30 included in the Video-TS directory 22 are basically the same. Of course, it may contain some different parts. The VTS 30 included in the Video—DC directory 21 and the VTS 30 included in the Video—TS directory 22 can be identified according to which directory they are recorded on, and are configured as described later. It can also be identified by a file identifier. Similarly, in practice, the data structures of the VMG 50 included in the Video—DC directory 21 and the VMG 50 included in the Video—TS directory 22 are basically the same. Of course, some different parts may be included. The VMG50 included in the Video—DC directory 21 and the VMG50 included in the Video—TS directory 22 are recorded in a misaligned directory and can be identified depending on whether they are recorded as described below. They can also be identified by the identifiers of the files that make up each.

FIG. 2 shows an example in which the Video-TS directory 22 includes one VTS 30, but it includes a plurality of VTSs 30!

[0066] As shown in FIG. 3, VTS30 is composed of VTSI (VTS Information) 31, VTSM—VOBS (Video Object Set for the VTS Menu) 32, and VTS—VOBS (Video Object Set for Titles in a VTS). 33 and VTSI—BUPS (VTSI Buck Up) 34.

[0067] The VTSI 31 is management information for managing the VTS 30. Video—VTSI31 in VTS30 included in DC directory 21 is composed of one file named “VTS— # # —0. IDC”. VTSI31 in VTS30 included in Video—TS directory 22 is also configured with one file power of “VTS— # # —0. IFO”. Note that “# #” is an identification number of VTS and is an integer of 1 or more according to the number of VTS30 included in the content (however, the upper limit may be set, for example, the upper limit may be set to 99) Are assigned in order.

[0068] The VTSM-VOBS 32 is data for various menus related to the VTS 30 (hereinafter, such menus are referred to as "title menus" as appropriate). VTSM—VOBS32 in VTS30 included in Video—DC directory 2 1 is composed of one file “VTS— # # —0. VDC”. VT in VTS 30 included in Video TS directory 22 SM—VOBS32 consists of a single file called “VTS— # # —0. VOB”.

[0069] Note that the "title menu" in this embodiment sets the playback condition for one title selected using, for example, the general menu described later (for example, selects the audio language during playback).

In addition, it is preferable that the parental lock is not applied to the VTS-VOBS 33 or the like in the Video-TS directory 22. In other words, VTS VOBS33 etc. in the Video_TS directory 22 can be played without any special processing. And are preferred.

[0073] The PGC used to regenerate the warning message display cell 61 is preferably a simple single PGC and a sequential PGC.

[0074] VTSI—BUPS34 is a backup of VTSI31. VTSI—BUPS34 in VTS30 included in Video—DC directory 21 consists of a single file “VTS— # # —0. BDC”. VTSI—BUPS34 in VTS30 included in Video—TS directory 22 is composed of one file “VTS— # # —0. BUP”.

[0075] VTSI31 is VTSI general information 35 for managing VTSI31 in general and PGCI (#m (where m is an integer of 1 or more)) that specifies the data to be reproduced in VTS30 (Program Chain Information # m) PGCI table 36 containing 38 and other information 37.

[0076] PGCI (#m) 38 is a playback unit specified by PGCI (#m) general information 39, command information table 40, and PGCl (#m) for managing PGCI (#m) 38 in general. A cell information table 41 containing information on the cell, and other information 42.

[0077] The command information table 40 includes a pre-command table 43 that specifies a pre-command to be executed before reproducing data specified by PGCI (#m), and data specified by PGCl (#m). It includes a post command table 44 for specifying a post command to be executed after playback, and a cell command table 45 for specifying a cell command to be executed after playback of a cell specified by PGCl (#m).

In this embodiment, in particular, at least one of the pre-command table 43, the post-command table 44, and the cell command table 45 included in the command information table 40 in the Video—TS directory 22 is a warning text display cell 61. Including a playback stop command 62 (one specific example of “stop command data” in the present invention) for stopping the playback operation after several seconds! Video—The pre-command table 43, the post-command table 44 and the cell command table 45 included in the command information table 40 in the DC directory 21 include a playback stop command 62! /, Or not! /.

[0079] As shown in Figure 4, VMG50 has VMGI (VMG Information) 51 and VMGM—VOBS

(Video Object Set for the VMG Menu) 52 and VMGI BUPS (VMGI Buck Up) 54 Including.

[0080] The VMGI 51 is management information for managing the entire content including the VMG 50. The VMGI 51 in the VTS 30 included in the Video—DC directory 21 is composed of one file “VIDEO—TS. IDC”. The VMGI 51 in the V TS 30 included in the Video—TS directory 22 is composed of one file “VIDEO—TS. IFO”.

[0081] VMGM—VOBS52 is a comprehensive menu for all content that includes VMG50.

(For example, a menu for selecting a desired title with a plurality of titles). The VMGM—VOBS52 in the VTS30 included in the Video—DC directory 21 is composed of one file “VIDEO—TS.VDC”. The VMGM—VOBS52 in the VTS30 included in the Video—TS directory 22 consists of “VIDEO—TS.VOB” and V, one file.

VMGI—BUPS54 is a backup of VMGI51. The VMGI-BUPS54 in the VTS30 included in the Video—DC directory 21 consists of one file “VIDEO—TS. BDC”. The VMGI-BUPS54 in VTS30 included in the Video—TS directory 22 is composed of one file “VIDEO—TS. BUP”.

[0083] VMGI51 records VMG general information 55 for general management of VMGI51, and the first page GC of title # 1 (where 1 is an integer equal to or greater than 1) recorded in optical disc 10 And other information 57 including a title search pointer indicating the address being stored.

The VMG general information 55 includes FP-PGC 59 that designates data to be reproduced first when the optical disc 10 is reproduced, and other information 60 including a disc region and the like!

[0085] FP—PGC59 constitutes one specific example of “sequence data” in the present invention, and designates data (specifically, PGC) to be reproduced after the optical disc 10 is loaded into the information reproducing apparatus. To do. Particularly in the present embodiment, the FP-PGC 59 is composed of VTS # 1 (more specifically, a warning message display cell 61 or a warning message display) of the VTS-VOBS33 in the Video-TS directory 22 described above. Specify title # 1) including cell 61.

[0086] In the optical disc 10 having such a data structure, data is reproduced in the order shown in FIG. It is. As shown in FIG. 5, the content recorded on the optical disc 10 is played back mainly in PGC units. The PGC corresponds to a combination of PGCI38 and data specified by the PGCI38. Of course, it goes without saying that the data specified by PGCI 38 in the PGCI table 36 is reproduced after the data specified by FP-PGC 59 is reproduced.

When reproducing one PGC, first, PGC setting information (eg, PGCI general information) is acquired, and a pre-command specified by the pre-command table 43 is executed. After that, content playback proceeds in units of cells specified by PGCI38. A cell is composed of a combination of a navigation pack and data (for example, a video pack, an audio pack, a sub-picture pack, etc.) whose playback is controlled by the navigation pack.

[0088] A navigation command can be designated in the navigation pack, and the navigation command can be executed before data reproduction. In the navigation command, a command for executing a predetermined process after a predetermined time has elapsed can be set. Specifically, a button command for displaying a transparent button that is not displayed on the display is set in the navigation command, and if the button command is not selected and executed for a certain period of time, a predetermined process is automatically performed. Can be configured to run on.

After the reproduction of one cell is completed, the cell command specified by the cell command table 45 is executed. After that, the next PGC regeneration is performed in the same procedure.

Note that the example shown in FIG. 5 describes an example in which one cell is included in one PGC. Of course, one PGC may be configured to include a plurality of cells. In this case, after the reproduction of one cell is completed (that is, after the cell command is executed), the execution of the next cell is sequentially performed in the same procedure as described above. After the playback of the last cell included in one PGC is completed, the post command specified by the post command table 44 is executed. After that, the next PGC is regenerated in the same procedure.

Accordingly, for example, a new information reproducing apparatus capable of recognizing the Video—DC directory 21 suitably reproduces content such as a movie by reading the VTS 30 and VMG 50 recorded in the Video—DC directory. be able to.

[0092] On the other hand, an old-fashioned information reproducing apparatus that cannot recognize the Video—DC directory 21 ( In other words, an old-fashioned information playback device that can only recognize the Video—TS directory 22) cannot read VTS30 and VMG50 recorded in the Video—DC directory 21, but records in the Video—TS directory 22. Read VTS30 and VMG50. Then, FP—PGC59 in VMG50 recorded in Video—TS directory 22 is composed of warning text display cell 61 in VTS30 or designates title # 1 including warning text display cell 61 . For this reason, in the old information reproducing apparatus, when the optical disk 10 is loaded, a warning text is first displayed.

[0093] As shown in FIG. 6, the warning message display cell 61 is “Warning. This disc cannot be played on your player. Play it on the corresponding player! /,” T, It may be a still image showing a warning text. Alternatively, it may be a moving image or sound as long as it can be shown to the user that the loaded optical disc 10 cannot be reproduced. As a result, the user can preferably recognize that the loaded optical disk 10 cannot be reproduced.

Thereafter, the playback operation is stopped by a playback stop command 62 specified as a cell command, pre-command, or post-command.

For example, when the playback stop command 62 is designated as a pre-command, the playback stop command 62 is executed before the playback of the warning text display cell 61 is started. Therefore, when the playback stop command 62 is designated as a pre-command, the playback stop command 62 is executed after the playback of the warning message display cell 61 has started and several seconds (for example, 10 seconds) have elapsed. It is preferable that the command is to stop the playback operation of the information playback device.

For example, when the playback stop command 62 is designated as a cell command or a post command, the playback stop command 62 is executed after the playback of the warning text display cell 61 is completed. Therefore, when the playback stop command 62 is designated as a cell command or post command, the playback stop command 62 stops the playback operation of the information playback device after the playback of the warning message display cell 61 is completed. Preferred to be a command.

Furthermore, the playback stop command 62 may be specified as a navigation command in the navigation pack.

Thereby, the reproducing operation of the information reproducing apparatus after the warning text is displayed is stopped. Therefore, even when the optical disc 10 in which the content is recorded in the Video-DC directory 21 is loaded into the old information reproducing apparatus, there is no possibility that an unintended operation in the information reproducing apparatus occurs. That is, the operation of the old information reproducing apparatus can be terminated in a suitable manner.

As described above, according to this embodiment, when the Video—DC directory 21 is recorded, the operation of the information reproducing apparatus that cannot recognize the Video—DC directory 21 is preferably terminated. Can be made.

[0100] In the above-described embodiment, the specific example in which the VTS 30 includes the warning message display cell 61 and the reproduction stop command 62 has been described. However, each of the warning message display cell 61 and the playback stop command 62 may be included in the VMG 50. Specifically, the warning message display cell 61 is included in the VM GM-VOBS 52 so that the warning message shown in FIG. The playback stop command 62 may be designated as a pre-command, post-command, or cell command using the PGCI table 36 (not shown).

[0101] Furthermore, instead of including each of the warning text display cell 61 and the playback stop command 62 in the VMG50, when there is an instruction to display the general menu, the playback text is displayed in the VTS30. The VMG 50 may be configured to skip to title # 1, which is configured with the cell 61 for use or includes the warning message display cell 61. Specifically, the title is composed of the warning message display cell 61 stored in VTS # 1 in VTS30 by the title search pointer included in the other information 57, or includes the warning message display cell 61. In addition to specifying # 1, the playback destination is specified by the title search pointer using the pre-command, post-command, and cell command specified by the PGCI table 36 (not shown) included in the other information 60. You can configure it to skip to title # 1.

[0102] Thus, even when the user gives an instruction to display the general menu after the warning message is displayed and the playback operation is stopped by loading the optical disc 10, the warning message is displayed again. Display and playback operation can be stopped. This eliminates the possibility of an unintended operation due to a user operation in the information reproducing apparatus once the reproduction operation is stopped. In other words, the operation of the old information playback device It can be terminated in a suitable manner.

[0103] Also, instead of including each of the warning message display cell 61 and the playback stop command 62 in the VTS 30, each of the warning text display cell 61 and the playback stop command 62 is configured to be included only in the VMG50. Even so.

Further, in the above-described embodiment, the description of the example in which the warning text display cell 61 is configured as one cell has been advanced. The warning text display cell 61 may be configured as a plurality of cells. Needless to say,

[0105] Further, in the above-described embodiment, the description has been made on the configuration in which the warning text is displayed and the reproduction operation is stopped using one PGC. However, it may be configured to use multiple PGCs to display warning text and stop playback. When multiple PGCs are used, a warning message is displayed using the first PGC specified by FP-PGC59, and a playback stop command is issued by the second PGC that is played following the first PGC. Configure VTS # 1 (in other words, title # 1 consisting of warning text display cell 61 or including warning text display cell 61 and with playback stop command 62 set) A little.

[0106] (3) Basic configuration of recording system

Subsequently, the basic configuration of the recording system 1 according to the present embodiment will be described with reference to FIG. 7 and FIG. Here, FIG. 7 is a block diagram schematically showing the basic configuration of the recording system 1 according to the present embodiment, and FIG. 8 is an information recording apparatus 100 constituting the recording system 1 according to the present embodiment. It is a block diagram which shows notionally the basic composition.

The information recording device 100 constitutes a specific example of the “information recording device” in the present invention, and the content stored in the hard disk 301 provided in the distribution server 300 is transferred to the communication network network. It can be obtained (ie, downloaded) via 200 and recorded on the optical disc 10. A plurality of information recording devices 100 may be connected to the communication network 200.

Communication network 200 is a network that connects information recording device 100 and distribution server 300. It is a work network. The communication network 200 may be a dedicated line, a general public line or a telephone line, a packet network, or a circuit switching network. The Internet may be adopted as the communication network 200. The communication network 200 may be a wireless network such as a mobile phone network, IMT-2000, PHS, or wireless LAN. It should be noted that some of the communication lines between the information recording apparatus 100 and the distribution server 300 are not necessarily wired or wireless, and some of the communication lines are wired and other parts of the communication network 300 are not. It may be wireless.

The distribution server 300 includes a hard disk 301 and is connected to the information recording apparatus 100 via the communication network network 200. The hard disk 301 included in the distribution server 300 stores content including one or more movies, television programs, and the like. Then, the distribution server 300 distributes the content stored in the hard disk 301 to the information recording device 100 in response to a request from the information recording device 100.

As shown in FIG. 8, the information recording apparatus 100 includes a disk drive 110 in which the optical disk 100 is actually loaded and content is recorded, a personal computer that controls content recording in the disk drive 110, and the like. Host computer 120.

[0112] The disk drive 110 includes an optical disk 10, a spindle motor 111, an optical pickup 112, a signal recording unit 113, a CPU (drive control unit) 114, a memory 115, a data input / output control unit 116, and a bus 117. Yes. The host computer 120 includes a CPU 121, a memory 122, an operation Z display control means 123, an operation button 124, a display panel 125, a data input / output control means 126, and a bus 127.

The spindle motor 111 rotates and stops the optical disc 10 and operates when accessing the optical disc 10. More specifically, the spindle motor 111 is configured to rotate and stop the optical disc 10 at a predetermined speed while receiving spindle servo from a servo unit (not shown) or the like.

The optical pickup 112 includes, for example, a semiconductor laser element (not shown), a collimator lens, an objective lens, and the like in order to perform recording / reproduction on the optical disc 10. More specifically, the optical pickup 112 regenerates a light beam such as a laser beam to the optical disc 10. When reading, the reading light is irradiated with the first power, and during recording, the writing light is irradiated with the second power and modulated.

[0115] The signal recording means 113 constitutes a specific example of the "first recording means" and the "second recording means" in the present invention, and the spindle motor 111 and the optical pickup 112 are controlled while being controlled by the CPU 114. Recording is performed on the optical disc 10 by controlling. More specifically, the signal recording / reproducing means 113 includes, for example, a laser diode driver (LD driver) and a head amplifier. The laser diode driver generates a driving pulse, for example, and drives a semiconductor laser element provided in the optical pickup 112. The head amplifier amplifies the output signal of the optical pickup 112, that is, the reflected light of the light beam, and outputs the amplified signal.

The CPU (drive control means) 114 is connected to the signal recording means 113 and the memory 115 via the bus 117, and controls the entire disk drive 110 by giving instructions to various control means. Usually, software or firmware for operating the CPU 114 is stored in the memory 115.

[0117] The memory 115 is used in general data processing in the disk drive 110, such as a buffer area for recording data and an area used as an intermediate buffer when data is converted into data usable by the signal recording means 113. . In addition, the memory 115 is a program for performing operations as these recorder devices, that is, a ROM area in which firmware is stored, and a variable that is temporarily stored in recording data or necessary for operations such as a firmware program. It is composed of a RAM area in which is stored.

The data input / output control means 116 controls data input / output from the host computer 120 to the disk drive 110. A drive control command issued from an external host computer 120 connected to the disk drive 110 via an interface such as SCSI or ATAPI is transmitted to the CPU 114 via the data input / output control means 116. Similarly, the recording data is exchanged with the host computer 120 via the data input / output control means 116.

[0119] The operation Z display control means 123 is for receiving and displaying an operation instruction for the host computer 120. Show) to CPU121. Based on the instruction information from the operation Z display control means 123, the CPU 121 transmits a control command (command) to the disk drive 110 via the data input / output means 126 to control the entire disk drive 110. Similarly, the CPU 121 can transmit a command requesting the disk drive 110 to transmit the operation state to the host computer 120. As a result, since the operation state of the disk drive 110 (for example, the recording execution state or the recording interruption state) can be grasped, the CPU 121 can be connected to the display panel 125 such as a fluorescent tube or LCD via the operation Z display control means 123. It is possible to output the operation state.

Furthermore, the data input / output control means 126 acquires the content acquired from the distribution server 300 via the communication network 200 under the control of the CPU 121, and outputs the acquired content to the disk drive 110. To do.

[0121] The CPU 121 controls the entire host computer 120.

[0122] The memory 122 is an internal storage device used by the host computer 120. For example, a ROM area in which a firmware program such as BIOS (Basic Input / Output System) is stored, an operating system, an operation of an application program, etc. It consists of a RAM area that stores variables and other necessary variables.

[0123] (4) Operating principle of recording system

Next, the operation principle of the recording system 1 according to the present embodiment (specifically, the operation principle of the information recording apparatus 100) will be described with reference to FIG. FIG. 9 is a flowchart conceptually showing a flow of operations of the recording system 1 in the example.

As shown in FIG. 9, content (specifically, VTS 30 and VMG 50 described above) is downloaded from distribution server 300 to information recording device 100 (step S 101). Thereafter, the downloaded content is recorded in the Video-DC directory 21 by the operation of the information recording apparatus 100 (step S102).

Subsequently, it is determined whether or not the content downloaded in step S101 includes the Video-TS directory 22 in addition to the Video-DC directory 21 (step S103).

[0126] As a result of the determination in step S103, the code downloaded in step S101 is displayed. If it is determined that the Video—TS directory 22 is included in addition to the Video—DC directory 21 (step S 103: Yes), the downloaded Video—TS directory 22 is stored in the optical disc 10. To be recorded.

On the other hand, as a result of the determination in step S103, if it is determined that the content downloaded in step S101 does not include the Video—TS directory 22 2 in addition to the Video—DC directory 21 (Step S 103: No) Next, whether the Video—TS directory 22 having the above-described configuration (that is, including the warning message display cell 61 and the playback stop command 62) has already been recorded on the optical disk 10. It is determined whether or not (step S104). Specifically, the manufacturer of the optical disc 10 determines whether or not the Video-TS directory 22 having the above-described configuration has been recorded in advance.

[0128] As a result of the determination in step S104, if it is determined that the Video—TS directory 22 having the above-described configuration has not yet been recorded (step S104: No), the operation of the information recording apparatus 100 After the Video-TS directory 22 having the above-described configuration is created (step S105), the created Video-TS directory 22 is recorded on the optical disc 10 (step S106). Thereafter, the recording operation ends.

On the other hand, as a result of the determination in step S104, when it is determined that the Video-TS directory 22 having the above-described configuration has already been recorded (step S104: Yes), the recording operation ends.

That is, the Video-TS directory 22 having the above-described configuration may be configured to be downloaded from the distribution server 300 together with the Video-DC directory 21, or recorded in advance on the optical disc 10 !, It may be configured such that the information is recorded by the information recording apparatus 100 each time the Video—DC directory 21 is recorded. However, from the viewpoint of reducing the processing burden on the information recording apparatus 100, the Video-TS directory 22 is preferably configured to be downloaded from the distribution server 300 together with the Video-DC directory 21.

[0131] The optical disc 10 on which the recording operation has been performed in this way has the data structure described with reference to Figs. Therefore, it is possible to enjoy the same effects as those that can be enjoyed by the optical disc 10 described above. In other words, for example, Video—DC directory 21 is recognized. The new information reproducing apparatus that can perform the reproduction of contents such as movies can be suitably reproduced by reading the VTS 30 and VMG 50 recorded in the Video—DC directory. On the other hand, in the old information reproducing apparatus that cannot recognize the Video-DC directory 21, the reproducing operation is stopped after the warning text is displayed. Therefore, even when the optical disc 10 in which the content is recorded in the Video-DC directory 21 is loaded onto an old-style information reproducing device, there is no possibility of an unintended operation in the information reproducing device. That is, the operation of the old information reproducing apparatus can be terminated in a suitable manner.

In the above recording operation, the configuration in which the Video-TS directory 22 is downloaded or recorded after the Video-DC directory 21 is first downloaded and recorded has been described. That is, the configuration in which the inner peripheral side force of the optical disc 10 is also directed toward the outer peripheral side, and the forces of the Video-DC directory 21 and the Video-TS directory 22 are recorded in this order has been described. However, it goes without saying that the Video-DC directory 21 may be downloaded or recorded after the Video-TS directory 22 is first downloaded and recorded. That is, it goes without saying that the inner-side force of the optical disc 10 may also be recorded in this order in the order of the video-TS directory 22 and the video-DC directory 21 toward the outer-periphery side.

[0133] Further, the recording system 1 described above may be applied to a system having a configuration other than a distribution system that acquires content via the communication network 200. For example, the information recording apparatus 100 may be applied to a system that performs an operation of acquiring content using some means with a certain recording power. Even in this case, the above-described various benefits can be enjoyed.

In the above-described embodiment, the power described for the optical disc 10 as an example of an information recording medium and the recorder related to the optical disc 10 as an example of an information recording device. The present invention is limited to an optical disc and its recorder. Therefore, the present invention can be applied to other information recording media and recorders corresponding to other high density recording or high transfer rate.

[0135] The present invention is not limited to the above-described embodiments, but can be appropriately modified within the scope of the appended claims and the entire specification without departing from the gist or concept of the invention. An information recording medium, an information recording apparatus and method, and a computer program with such changes are also included in the technical scope of the present invention.
