Description

  The present invention includes a plurality of information recording layers having different recording characteristics, a recording / reproducing apparatus, an optical disc, and a recording medium that can also read information recorded on a ROM layer by reading information recorded on the RE layer or R layer The present invention relates to a playback apparatus control method and a recording / playback apparatus control program.

  In recent years, for the purpose of improving the security of OS (Operating System) and applications, and for the purpose of upgrading to a more usable version, there are many opportunities to install update information etc. frequently using the Internet. Yes.

  Furthermore, optical information recording media such as optical discs have recently increased in recording capacity. For example, a single DVD-ROM (Digital Versatile Disc-Read Only Memory) can store video / audio data of about 200 minutes. You can record. In the future, with the advent of Blu-ray Disc (registered trademark) and the like, the recording capacity of the optical disk will increase more and more, and it will take 2 to 3 hours for high definition image quality and 4 to 10 hours for standard image quality on one optical disk. / Audio data can be recorded.

  Under such circumstances, a technique has been developed in which update information is recorded on an optical information recording medium such as an optical disc having an increased recording capacity, and the optical information recording medium is always updated to the latest version. Such a technique is disclosed in Patent Documents 1 and 2, for example.

  Specifically, the recording medium system (DVD system) of Patent Document 1 includes a ROM area and a RAM area, records basic data in the ROM area, and stores addition / update / deletion information received via the network in the RAM area. Is writing. The DVD system reads out the data in the ROM area and the RAM area, and outputs the same data as the latest version of the DVD disk by linking and synchronizing the respective data. It is possible to use as.

  In the method of accessing electronic content on the network described in Patent Document 2, the user accesses and acquires the content supplier database on the network using an authentication hybrid optical disc provided with an identification signature or encryption information. Content is stored in the RAM area of the optical disc. This makes it possible to access information on the network safely and conveniently and store the latest information acquired in the RAM area.

  As another patent document, Patent Document 3 discloses a method for managing acquired update information and the like. Specifically, the disk recording device of Patent Document 3 provides a file management area in the RAM area at the time of formatting, transfers the file management information recorded in the ROM area to the RAM area, and manages the file each time it is recorded in the RAM area. Information is being updated. As a result, the data files recorded in the ROM area and the RAM area are centrally managed to facilitate the management of acquired information.

  In addition, the optical disk playback device described in Patent Document 4 stores the selected angle video in a nonvolatile memory included in the device during playback of the optical disk on which the multi-angle video is recorded, and plays back the optical disk again. At this time, the stored angle video is reproduced from the non-volatile memory. Then, the optical disc playback apparatus can view the same angle video as when viewed before, and can change or delete the stored angle video.

  Also, the multi-angle playback device described in Patent Document 5 stores angle video data as display data when displaying an optical disc on which multi-angle video is recorded, and displays each of the plurality of display data within one screen. Thus, the user can select and perform normal reproduction and angle reproduction automatically.

Japanese Patent Laid-Open No. 11-144322 (published on May 28, 1999) JP 2003-100013 A (published April 4, 2003) JP 7-182218 A (published July 21, 1995) JP 2002-252833 A (published on September 6, 2002) Patent No. 3765724 (registered on February 3, 2006)

  However, the technique of Patent Document 2 is premised on connecting to a network for authentication and content browsing display, and since it starts from the ROM area, there is no traffic between the ROM area and the RAM area. Become frequent. Further, since the disc is used for authentication and the content itself is not recorded on the medium, it takes a long time to download the content, which is inconvenient for the user.

  In Patent Documents 1 and 3, the ROM area and the RAM area are provided in the same layer, and the recorded data files are centrally managed. Therefore, in the techniques of Patent Documents 1 and 3, when the information recording layer is multi-layered and the ROM area and the RAM area are provided in different layers, it is difficult to perform unified management across both layers. Further, since the file management area is provided in the RAM area located in the middle of the disk, the information of the file management area originally recorded in the ROM area is first read when the disk is introduced. Therefore, even if the file management information recorded in the ROM area is transferred to the RAM area, it is unlikely that the file management information is practically used for centralized management. Furthermore, since the file management information in the ROM area is transferred before (inner circumference side) the file management information in the RAM area, it is necessary before reading the file management information in the RAM area in which information indicating a user instruction is recorded. There is a problem in that the management information of the ROM layer without reading is read, and the processing speed is reduced due to useless operations and the power consumption is increased.

  In Patent Documents 4 and 5, an angle video that is recorded in the ROM layer of the information recording medium and that the user desires to view is recorded on the recording medium on the recording / reproducing apparatus side. Therefore, when the information recording medium is inserted into another recording / reproducing apparatus, the user has to select an angle video again with the other recording / reproducing apparatus, which places an excessive burden on the user. . This is because the angle video that the user desires to view cannot be recorded on the information recording medium, that is, the angle video is recorded on the information recording medium and the recording medium on the recording / reproducing apparatus side. This problem was caused by the problem that unification of the data could not be unified.

  The present invention has been made to solve the above-described problems, and its purpose is to be able to additionally record information or rewrite information in an information recording medium in which information recording layers are multilayered. Control of a recording / reproducing apparatus, an optical disc, and a recording / reproducing apparatus that can efficiently read out registration information recorded in the information recording layer that can only read out information by reading out information recorded in the information recording layer A method and a recording / reproducing apparatus control program are provided.

The recording / reproducing apparatus according to the present invention comprises:
Information is recorded on or reproduced from an optical disc provided with a first information recording layer capable of only reading information and a second information recording layer capable of additionally recording information or rewriting information. A recording / reproducing apparatus,
Reading means for reading registration information which is information recorded in the first information recording layer;
Recording control means for recording at least a part of the registration information read by the reading means on the outer peripheral side of the recording start position of the file management information for managing the file recorded in the second information recording layer; It is characterized by providing.

Also, the optical disc according to the present invention is
An optical disc comprising: a first information recording layer capable of only reading information; and a second information recording layer capable of additionally recording information or rewriting information,
At least a part of the registration information, which is information recorded in the first information recording layer, is on the outer periphery side from the recording start position of the file management information for managing the file recorded in the second information recording layer. It is characterized by being recorded in.

In addition, the control method of the recording / reproducing apparatus according to the present invention includes:
Information is recorded on or reproduced from an optical disc provided with a first information recording layer capable of only reading information and a second information recording layer capable of additionally recording information or rewriting information. A method for controlling a recording / reproducing apparatus, comprising:
A reading step of reading registration information which is information recorded in the first information recording layer;
Recording for recording at least a part of the registration information read in the reading step on the outer peripheral side from the recording start position of the file management information for managing the file recorded in the second information recording layer And a control step.

  According to the above configuration, the optical disc inserted into the recording / reproducing apparatus according to the present invention includes the first and second information recording layers, and the first information recording layer is an information recording layer that can only read information. The second information recording layer is an information recording layer capable of additionally recording information or rewriting information. In the recording / reproducing apparatus, the reading unit reads the registration information recorded on the first information recording layer, and the recording control unit records at least a part of the registration information on the second information recording layer.

  Accordingly, at least a part of the registration information recorded in the second information recording layer only by the reading operation to the second information recording layer (hereinafter, at least a part of the registration information recorded in the second information recording layer is “copied”). Information ”), and the reading operation to the first information recording layer is not necessary. This eliminates the need to jump between the first information recording layer and the second information recording layer to read the copy information from the first information recording layer, thereby increasing the processing speed of the recording / reproducing apparatus.

  Further, in the recording / reproducing apparatus according to the present invention, the copy information is recorded on the outer peripheral side from the recording start position of the file management information for managing the file recorded in the second information recording layer. .

  Therefore, when the optical disc is inserted into the recording / reproducing apparatus according to the present invention, the file management information of the second information recording layer is first read. Here, in general, since the file management information is recorded with user instructions and the like, it is only necessary to read other information based on the instructions and the like, and the information is recorded in the first and second information recording layers. Substantially centralized management of various information is possible. Since the file management information in which user instructions are recorded is read before the copy information, a reduction in processing speed and power consumption due to useless operations caused by reading unnecessary copy information. The problems of Patent Documents 1 and 3 such as an increase in Further, since it is not necessary to record the registration information in the memory on the recording / reproducing apparatus side, unified management of information on the optical disk side, which could not be solved by the techniques of Patent Documents 4 and 5, can be realized.

Therefore, the number of operations can be reduced, and as a result, the frequency of failures occurring in the recording / reproducing apparatus can be suppressed.

  In addition, the copy information is recorded in the second information recording layer of the optical disc, not in the memory on the recording / reproducing apparatus side. Therefore, since the copy information is recorded on the second information recording layer when the optical disk is taken out from the recording / reproducing apparatus according to the present invention, the second information recording layer is used even when the optical disk is used in another recording / reproducing apparatus. By simply reading the information recorded on the information recording layer, it is possible to read the copy information originally recorded on the first information recording layer. Thereby, also in the other recording / reproducing apparatus, since the reading operation to the first information recording layer can be omitted, the processing speed of the apparatus can be increased.

  Further, when updating (latest) information is acquired for the purpose of improving the security of the OS, applications, etc., or for upgrading to a more user-friendly one, and the updated information is recorded on the optical disc, the information is additionally recorded. Alternatively, update information is recorded in the second information recording layer where information can be rewritten. Therefore, since the copy information is recorded in the second information recording layer, there is an effect that the copy information, update information, and the like can be managed in the second information recording layer. This eliminates the need to record copy information, update information, and the like on a recording medium on the recording / reproducing apparatus side, and realizes unified management of information on the optical disk side, which cannot be solved by Patent Documents 4 and 5.

Furthermore, in the recording / reproducing apparatus according to the present invention,

FIG. 3 is a diagram illustrating a configuration example of each recording layer of the optical disc 100.

  As shown in FIG. 3, the recording layer L0 is called the recording layer L0, L1,... From the recording layer farthest from the reproducing light incident side, the recording layer L0 is the RE layer (second information recording layer), and the recording layer L1 is the ROM layer ( The configuration of the optical disc 100 in the case of the first information recording layer) is shown. As shown in the figure, a recording layer L0 (RE layer) and L1 (ROM layer) are provided with a BCA (Burst Cutting Area) 101, a lead-in area 102, a user data area 103, and a lead-out area 104. In the figure, the BCA 101 exists only in the L0 (RE layer), but may exist only in the L1 (ROM layer), or may exist in both layers.

  The BCA 101 is an innermost circumference of the optical disc 100, which is an area that does not require tracking control or a bar code-shaped recording area that can be accessed only by focus control. The optical disc apparatus (recording / reproducing apparatus) 1 is designed so that the information of the BCA 101 is read first when the optical disc 100 is inserted. The BCA 101 is an area in which information can be written only at the time of manufacture (that is, an area that cannot be rewritten).

  The BCA 101 mainly stores identification information indicating the structure of the optical disc. Specific examples of the identification information include the recording layer type (reproduction-only type, write-once type, and rewritable type) of the optical disc 100, the size of the optical disc 100, the standard version of the optical disc 100, and the number unique to the optical disc 100. In general, the recording order (or arrangement method) of each identification information is determined by a standard or the like.

  The lead-in area 102 is an area provided for each recording layer on the outer peripheral side of the BCA 101 in the optical disc 100. Further, the lead-in area 102 is inserted into the optical disc apparatus 1 in the case of a write-once type or a rewritable type as well as an area in which information can be written only at the time of manufacture (that is, a non-rewritable area). After that, an area where information can be additionally recorded or rewritten is provided. In the lead-in area 102, for example, standard conditions for recording / reproduction on the optical disc 100, information indicating permission / non-permission (access restriction) of access of the optical disc apparatus 1 to each layer, defects at the time of manufacturing, and defects generated during use Information indicating the position is recorded.

The user data area 103 is an area in which various information such as basic software such as an OS (Operating System), applications, or contents and user data associated therewith are recorded (or recordable). Also, management information such as the position / address where these pieces of information are recorded and the correlation (file, directory root) of a plurality of pieces of information is also recorded.
For example, in the user data area 103 of the ROM layer, applications and contents prepared by the disk supplier are recorded in advance. In the user data area 103 of the RE layer, contents recorded by the user, application version upgrade information, Also, user data associated therewith is recorded by the optical disc apparatus 1.

  Hereinafter, information recorded in advance in L1 (ROM layer) is referred to as “registration information”. In the RE layer of the optical disc 100, a part of the registration information of the ROM layer is recorded (copied). This may be recorded (copied) in advance by the disk supplier, or may be recorded (copied) by the optical disk apparatus 1 on the RE layer. The registration information recorded (copied) in the RE layer is, for example, file management information recorded in the user data area 103 of the ROM layer. In another example, the registration information recorded (copied) in the RE layer is a part of the content recorded in the user data area 103 of the ROM layer.

Generate a signal. Further, in order to keep the intensity of the light emitted from the optical pickup 12 constant, the light reflected from a part of the optical pickup 12 is detected and a servo signal fed back to the laser drive circuit 14 is also generated.

  The spindle circuit 16 is for rotating the spindle 2, that is, the optical disc 100 at an optimum rotational speed when a drive instruction is given from the disc loading confirmation unit 22 or the operation unit 6.

  The optical pickup 12 is an optical system for condensing the light emitted from the laser onto the optical disc 100 and branching the reflected light from the optical disc 100 to guide it to the detection circuit 15.

  The control unit 20 is generally responsible for exchanges with external devices such as the inside of the optical disk device 1 and the memory 5, the operation unit 6, the display device 7, and the Internet terminal device 8. Unit 22 and recording / reproducing circuit group controller 23.

  The disk loading confirmation unit 22 confirms whether or not the optical disk 100 is inserted depending on whether or not a detection signal is received from the disk loading recognition unit 3.

  The recording / reproducing circuit group control unit 23 is for controlling the recording / reproducing circuit group 10. For example, the recording / reproducing circuit group control unit 23 converts an instruction input to the operation unit 6 into an input signal to the recording / reproducing circuit group 10. Further, a video signal and an audio signal are generated based on the RF signal obtained from the recording / reproducing circuit group 10 and input to the display device 7. These operations may be performed via the memory 5 due to problems such as processing speed and capacity. Further, when an Internet line is used for exchange with the optical disc apparatus 1, it is performed via the Internet terminal device 8.

  The optical disk device 1 has been described above. Here, generally, the optical disk device 1 is provided with a memory 5, an operation unit 6, a display device 7, an Internet terminal device 8, and the like. Hereinafter, these will be described. Note that the memory 5, the operation unit 6, the display device 7, the Internet terminal device 8, and the like may be included in the optical disc device 1.

The internet terminal device 8 is for connecting the optical disk device 1 to the internet line.
1-2. Operation Next, an outline of the operation of the optical disc apparatus 1 according to the present invention will be described.

  First, when the optical disc 100 is inserted into the optical disc apparatus 1, this is detected by the disc loading recognition unit 3. Then, a signal indicating that the optical disc 100 has been inserted into the optical disc apparatus 1 is transmitted from the disc loading recognition unit 3 to the disc loading confirmation unit 22 of the control unit 20. Next, the control unit 20 rotates the spindle 2 via the spindle circuit 16, and the optical disc 100 rotates at the set number of rotations. Note that the optical disc 100 has the structure described with reference to FIG. 3, and the registration information recorded in the ROM layer of the optical disc 100 may be recorded in the RE layer in advance.

  Next, the control unit 20 moves the optical pickup 12 via the pickup driving circuit 13 and irradiates the RE layer or the ROM layer with light via the laser driving circuit 14. Thereby, the recording / reproducing operation is performed. The reflected light is detected by the detection circuit 15, and the detection circuit 15 applies feedback with a servo signal. Based on the RF signal, the recorded information is read. At this time, the optical disc apparatus 1 may be set so as to preferentially read either the ROM layer or the RE layer, and at least one of the ROM layer and the RE layer is instructed to preferentially read the layer. Information may be recorded.

Further, when an external reading location instruction is input to the optical disc apparatus 1 via the operation unit 6 or the display device 7, a signal is sent from the control unit 20 to the recording / reproducing circuit group 10 according to the instruction. . The recording / reproducing operation is performed by the same operation as described above.
2． Example 1
Hereinafter, as a specific example of the optical disc 100 according to the present invention, a case where the management information of the ROM layer is copy information will be described.

  Hereinafter, the configuration of the optical disc 100 and the configuration / operation of the optical disc apparatus 1 will be described based on the above-described contents, and only different portions will be described.

  The optical disc 100 is sold by a supplier in which software, applications, and databases are recorded in the user data area 103 of the ROM layer. Information on the ROM layer includes, for example, software used in a personal computer, an application such as a car navigation system, a database such as a dictionary, and karaoke, and combinations thereof. Further, the ROM layer management information, which is copy information, may be recorded in the RE layer in advance when the optical disc 100 is released, or may be recorded (copied) in the RE layer by the optical disc apparatus 1 after the optical disc 100 is released. May be.

  A user who has purchased the optical disc 100 periodically checks upgrade information uploaded to a web page prepared by a supplier or the like via the Internet line while using each of the above software and applications. The upgrade information may be checked when the user likes it, or the optical disc 100 may have an automatic check function in advance.

  The optical disc apparatus 1 records the upgrade information on the RE layer of the optical disc 100 when the upgrade information exists. At this time, information such as which point of the original software or application has been upgraded and which part of the information recorded in the ROM layer is to be replaced is information on the RE layer. To record.

  On the other hand, in the optical disc 100, ROM layer management information as copy information is recorded in the RE layer in advance when the optical disc 100 is released, or is recorded (copied) by the optical disc apparatus 1 after the optical disc 100 is released. . Therefore, the management information of the ROM layer can be obtained by reading the information recorded in the RE layer, and no interlayer jump is required at that time.

  As described above, the RE upgrade information and the ROM layer management information are recorded in the RE layer of the optical disc 100. In other words, the correspondence between the newly recorded upgrade information and ROM layer management information can be included in the RE layer management information by the simple operation described above. In addition, since the management information of the ROM layer and the RE layer can be centrally managed in the RE layer, the information recorded on the optical disc 100 can be organized more easily. Further, when reproducing the optical disc 100 in which the upgrade information is recorded in the RE layer, first, the optical disc apparatus 1 reads the management information of the ROM layer and the RE layer recorded in the RE layer, so that the optical disc apparatus 1 If playback is performed, it can be recognized whether the upgrade information can be reflected.

  As described above, the management information of the ROM layer and the RE layer is centrally managed in the RE layer, so that the management information of the ROM layer and the RE layer can be acquired only by the reading operation to the RE layer. Therefore, it is not necessary to read the management information of the ROM layer and the RE layer from the respective layers, and it is possible to realize high-speed recording / reproduction processing both during recording and reproduction.

  Next, the RE layer area in which the ROM layer management information is recorded will be described with reference to FIG. FIG. 2 is a block diagram showing a route configuration of the optical disc 100.

  As shown in the figure, the file management information for the ROM layer may be recorded (copied) after (on the outer periphery side) the area where the file management information for the RE layer is recorded. That is, as shown in the figure, “data 1-2”, which is file management information for the ROM layer, is located after the area where “instruction 1-1”, which is file management information for the RE layer, is recorded (outside). “Data 2-1” is recorded. Alternatively, the ROM layer management information may be recorded (copied) as part of the RE layer management information. With this configuration, the optical disc 100 can be centrally managed mainly with a recordable RE layer.

  To further illustrate, when a database is recorded in the ROM layer, information instructing how the user wants to use the data in the ROM layer is recorded in the RE layer. Specifically, when PC software is recorded in the ROM layer, the RE layer includes the upgrade information and which information the upgrade information is recorded in the ROM layer should be upgraded. Instruction information is recorded. Further, when car navigation data is recorded in the ROM layer, information instructing the route by the user is recorded in the RE layer. In addition, when karaoke data is recorded in the ROM layer, the RE layer stores information indicating a list of songs and a key for each song. In addition, when data such as video and text information is recorded in the ROM layer, information instructing the display method of video and text information by the user is recorded in the RE layer.

  That is, since information indicating user instructions is recorded in the RE layer of the optical disc 100, once the information indicating these instructions is recorded in the RE layer, various data are stored in accordance with the instructions as shown in FIG. Regeneration is preferably performed. Therefore, since the management information of the ROM layer is recorded (copied) after or inside the area where the management information of the RE layer is recorded, the optical disc apparatus 1 is instructed by the user recorded in the RE layer. On the other hand, it is possible to recognize how the data in the ROM layer is used. Therefore, the processing operation is simplified, and high-speed startup and high-speed processing are possible.

  On the other hand, if the management information of the ROM layer is recorded (copied) before the area where the management information of the RE layer is recorded, when the optical disc 100 is inserted into the optical disc apparatus 1, first the ROM layer Management information is recognized. However, this operation also recognizes information that need not be recognized, and is a useless operation. Therefore, if the management information of the ROM layer is recorded (copied) before the area where the management information of the RE layer is recorded, the processing speed becomes slow and power consumption is wasted.

  It is also possible to record information indicating an instruction to read RE layer management information in an area before the ROM layer management information is recorded. However, it is necessary to read the instruction every time the optical disk 100 is inserted into the optical disk apparatus 1 and perform a reproduction operation, and then move the optical pickup 12 to the area where the management information of the RE layer is recorded. Will be generated. Therefore, even when information indicating an instruction to read RE layer management information is recorded in an area before the ROM layer management information is recorded, the processing speed is reduced and the power consumption is reduced. To waste.

Therefore, it is preferable that the ROM layer management information is recorded (copied) after or in the area where the RE layer management information is recorded.
3． Example 2: Multi-angle In the following, multi-angle video information is recorded on the ROM layer of the optical disc 100 according to the present invention, and the user selects one or a plurality of angle video information desired to be viewed from the multi-angle video information. In the case where the selected result is recorded in the RE layer, the outline will be described first, and then the example in which the copy information is a part of the multi-angle video information recorded in the ROM layer, and the management of the ROM layer An example of information will be described.

In the following, the configuration of the optical disc 100 and the configuration and operation of the optical disc apparatus 1 are based on the above-described contents, and only different portions will be described.
3-1. Information recorded in the recording layer L1 (ROM layer) of the optical disc 100 In this embodiment, multi-angle video information is recorded in the user data area 103 of the ROM layer. The multi-angle video information is a general term for video information obtained by shooting a certain shooting object from a plurality of angles and information related to the video information.

  The multi-angle video information includes at least single-angle video information (hereinafter referred to as angle video information) taken from one angle and angle video attribute information that is information related to the angle video information. Have about each. The multi-angle video information may exist over the entire recorded time, or may exist only during a part of the time.

  As described above, the angle video information represents information related to an angle video shot from one angle. More specifically, the information related to the angle video means still image data or moving image data indicating the angle video.

  The angle video attribute information includes attributes of individual angle videos such as a photographed object (person, object, landscape, etc.), a photographed angle (eg, shooting direction of a camera in a baseball field or a soccer field, a distance from the object, etc.). May be considered as information for explaining an angle video. The angle video attribute information is not limited to the attribute information described above, and may be configured to include information related to various videos.

  Note that the angle video information and the angle video attribute information are generated by at least the same number as the angle when the subject is shot from a plurality of angles. The angle video information and the angle video attribute information are generated at least as many times as the number of times of shooting when the angle positions of the plurality of angles are fixed. At this time, for example, if 10 still images are shot from one angle, the number of shots is 10. Or you may distinguish with the camera used for imaging | photography. In this case, the number of cameras is the number of angles.

  Further, in the ROM layer, when the user selects one or a plurality of angle video information (selected single angle video information) desired to be viewed from among a plurality of angle video information displayed on the display device 7, A selection example showing a specific example of the selection method may be recorded.

  Accordingly, the selection example is displayed on the display device 7 together with at least a part of the multi-angle video information read by the video information reading unit 24. Therefore, the user can select the selection example itself, or refer to this and select angle video information to view.

The ROM layer may include a connection image. The connected image is a case where a plurality of angle video information selected by the user is continuously played back, and when a playback time discontinuity occurs between two pieces of angle video information whose playback order is adjacent, It is an image inserted to fill the discontinuity.
3-2. More Detailed Configuration of Optical Disc Device 1 Next, the configuration of the optical disc device 1 in the present embodiment will be described with reference to FIG. FIG. 4 is a block diagram for explaining details of the recording / reproducing circuit group controller 23.

  In the optical disc apparatus 1 in the present embodiment, the recording / reproducing circuit group control unit 23 mainly includes a video information reading unit (reading unit) 24, a video display control unit (display control unit) 25, a selection request unit (selection unit) 26, A selection video recording control unit (recording control unit) 27 and a video insertion unit (insertion unit) 28 are provided. The recording / reproducing circuit group control unit 23 performs overall control of the video information reading unit 24, the video display control unit 25, the selection request unit 26, the selected video recording control unit 27, and the video insertion unit 28. In response to the instruction, the recording / reproducing circuit group 10 and the like are driven.

Hereinafter, details of each unit such as the video information reading unit 24 included in the recording / reproducing circuit group control unit 23 will be described.
3-2-1. Details of Each Unit Included in Recording / Reproducing Circuit Group Control Unit 23 The video information reading unit 24 receives the detection signal from the disc loading recognition unit 3 and the disc loading confirmation unit 22 receives the optical disc 100 from the optical disc apparatus 1. After confirming that it has been inserted, the multi-angle video information recorded in the ROM layer of the optical disc 100 is read out. As described above, the multi-angle video information includes at least a plurality of angle video information and the accompanying angle video attribute information.

  The video display control unit 25 acquires multi-angle video information from the video information reading unit 24 and displays the multi-angle video information on the display device 7 provided outside the optical disc apparatus 1. Details of the display method will be described later. Here, the display device 7 has been described as being provided outside the optical disk device 1, but the display device 7 may be incorporated in the optical disk device 1.

  The selection requesting unit 26 causes the user to select one or a plurality of angle video information desired to be viewed from the multi-angle video information displayed on the display device 7. Specifically, the selection request unit 26 outputs a selection request signal for causing the user to select one or more pieces of angle video information desired to be viewed, to the recording / reproducing circuit group control unit 23. In response to the selection request signal, the recording / reproducing circuit group control unit 23 requests the user to select angle video information desired to be viewed. At this time, for example, a selection request message such as “Please select the angle video you want to view” is displayed on the display screen of the display device 7, and the angle video information is set in a selectable state. It should be noted that the selection requesting unit 26 may be the entity that requests the user to select the angle video information desired to be viewed, instead of the recording / reproducing circuit group control unit 23.

  Next, the user selects one or a plurality of angle video information desired to be viewed from the multi-angle video information displayed on the display device 7 through an operation on the operation unit 6.

  The selected video recording control unit 27 specifies one or a plurality of angle video information selected by the user through the above-described operation in the operation unit 6, and a recording layer (L0 layer) capable of recording the one or a plurality of angle video information. ). Specifically, the recording / reproducing circuit group 10 that has received an instruction from the selected video recording control unit 27 sets recording conditions via the laser driving circuit 14, and sends a recording laser beam from the optical pickup 12 to L 0 of the optical disc 100. By irradiating the layer, one or more pieces of angle video information selected by the user are recorded on the optical disc 100.

  At this time, the selected video recording control unit 27 may record the selection result attribute information, which is information accompanying the selection result selected by the selection request unit 26 by the user, in the L0 layer. Note that the selection result attribute information is, for example, information on who made the selection and what was selected when the user registration or the like can be set in the optical disc apparatus 1.

  Thereby, when the optical disc 100 is inserted into the optical disc apparatus 1 again, the video display control unit 25 can display the selection result attribute information on the display device 7. Thereby, the user can know the presence and content of past selection results. Furthermore, the user can select angle video information that he / she wants to view anew with reference to the selection result. Further, even when the optical disc 100 is inserted into another optical disc apparatus, the selection result and the selection result attribute information can be displayed on the display device 7, so that the user can know the presence and content of past selection results. be able to. Furthermore, the user can select angle video information that he / she wants to view anew with reference to the selection result.

  Note that the selection request unit 26 requests the user to select a desired selection result and a selection example (not necessary) recorded in advance by the supplier. Specifically, the selection request unit 26 outputs a selection request signal for allowing the user to select a selection result and a selection example to the recording / reproducing circuit group control unit 23. In response to the selection request signal, the recording / reproducing circuit group control unit 23 requests the user to select a desired selection result and selection example. At this time, for example, a selection request message such as “Please select an option to be reproduced” is displayed on the display screen of the display device 7, and the selection result and the selection example are set to a selectable state. Note that the selection requesting unit 26 may be the subject that requests the user to select a desired selection result and selection example, instead of the recording / reproducing circuit group control unit 23.

  The video insertion unit 28 operates when continuously reproducing different angle video information. Specifically, when two pieces of angle video information that are adjacent to each other are reproduced, and the angle video information shot at different angles and at different times are continuously reproduced, the two angle video information is reproduced. There may be discontinuities in time. In such a case, unnaturalness may occur in the connection between two pieces of angle video information due to the discontinuity such as a display screen in which nothing is displayed.

  At this time, the video insertion unit 28 inserts a connection image for filling the discontinuity between two pieces of angle video information. Thereby, the unnaturalness that has occurred in the connection between the two pieces of angle video information can be reduced.

  Note that the video insertion unit 28 is a known technique such as a morphing technique for complementing and creating a video while being deformed by a computer, or a scene change technique for automatically generating a connected image by detecting a change in luminance or color difference. Can be applied. And by the said technique, a fade-out effect and a gradation effect are implement | achieved between two angle video information, and the unnaturalness of the connection of the two angle video information resulting from the said discontinuity can be reduced. . The video insertion unit 28 may use conventional techniques such as a morphing technique and a scene change technique, and a detailed description thereof will be omitted here.

Further, the connection image may be recorded in advance in the ROM layer of the optical disc 100, or may be acquired by the optical disc device 1 via the Internet terminal device 8 connected to the outside.
3-3. Process Flow after Inserting Optical Disc 100 into Optical Disc Device 1 Next, FIG. 5 shows the process flow of each unit included in the control unit 20 described in [Details of Each Unit Included in the Control Unit 20]. The description will be given with reference.

  FIG. 5 is a flowchart showing a flow of processing after the optical disc 100 is inserted into the optical disc apparatus 1.

  First, in S10, the optical disc 100 is inserted into the optical disc apparatus 1. The optical disc 100 has the structure described with reference to FIG. 3, and the various information (registration information) described in [Information recorded in the recording layer L1 (ROM layer) of the optical disc 100] is provided. It is assumed that it is recorded in the ROM layer in advance.

  Next, in S12, the control unit 20 drives the optical pickup 12 via the pickup driving circuit 13, and the information recorded in the RE layer is read. At this time, it is preferable to set the RE layer to be read preferentially over the ROM layer, and to set the ROM layer to be read only when no data is recorded in the RE layer. Thereby, information recorded in the RE layer can be preferentially read.

  Subsequently, in S14, it is confirmed whether the selection result and the selection result attribute information are recorded in the ROM layer. If the selection result and the selection result attribute information are recorded, the video display control unit 25 determines the selection result and / or the selection result attribute. Information is displayed on the display device 7 (S16). When the optical disc 100 is inserted into the optical disc apparatus 1 for the first time, the selection result and selection result attribute information may not be recorded in the RE layer. In this case, NO is determined in S14 and the process proceeds to S20.

  In S18, based on the selection result and selection result attribute information displayed on the display device 7, the user determines which selection result and selection result attribute information to select.

  As a specific processing flow, the selection request unit 26 outputs a selection request signal for allowing the user to select a selection result and selection result attribute information to the recording / reproducing circuit group control unit 23. The recording / reproducing circuit group control unit 23 receives the selection request signal and requests the user to select a desired selection result and selection result attribute information. At this time, for example, a selection request message such as “Please select a selection result to be reproduced” is displayed on the display screen of the display device 7, and the selection result and the selection result attribute information are set in a selectable state. In the above description, the subject that requests the user to select the selection result and the selection result attribute information is the recording / reproducing circuit group control unit 23. However, the selection requesting unit 26 may be used.

  S20 corresponds to the case where there is no selection result and selection result attribute information to be reproduced in S18. On the other hand, if there is a selection result to be reproduced and selection result attribute information, the process proceeds to S26 by selecting the selection result.

  In S <b> 20, the video display control unit 25 acquires the multi-angle video information from the video information reading unit 24 and causes the display device 7 to display the multi-angle video information.

  In S22, the selection request unit 26 causes the user to select one or more pieces of angle video information desired to be viewed from the multi-angle video information displayed on the display device 7. Since the details have been described above, description thereof is omitted here.

  Next, in S24, the selection video recording control unit 27 specifies one or a plurality of angle video information that the user desires to view through the selection operation by the user on the operation unit 6, and the one or the plurality of angle videos. Information is recorded in the RE layer. As the selection operation is performed, the RE layer may be sequentially recorded, or may be sequentially recorded in the memory 5, and may be recorded together in the RE layer when all the selections are completed.

Finally, in S26, the selection content (one or a plurality of angle video information that the user desires to view) recorded in the RE layer is reproduced, and the user can view the angle video information that the user desires. The reproduction of the selected content in S26 can be performed by another optical disk device. For example, the selection and recording of the multi-angle video information in S20 to S24 is performed by a personal computer having high operability, and the selection content in S26 is reproduced on the optical disc apparatus 1 attached to the personal computer for viewing on a television with good image quality. May be reproduced by another optical disc apparatus 1.
3-3-1. Next, a display method in which the video display control unit 25 displays the multi-angle video information acquired from the video information reading unit 24 on the display device 7 and allows the user to select the display method will be described.

  First, the video display control unit 25 displays all the multi-angle video information on one screen of the display device 7. At this time, the angle video information is displayed separately for each angle. Therefore, the display screen is divided by the number of angles. In addition, angle video attribute information indicating information related to a photographed angle may be displayed on the screen.

  According to the above configuration, since the multi-angle video information is displayed on one screen of the display device 7, the user can check all the angle video information at a glance and easily and quickly select the angle video information to be selected. can do. In addition, the angle video information included in each angle may be configured to be displayed in units of time.

  Alternatively, as another display method of the multi-angle video information, the video display control unit 25 may display all the angle videos simultaneously on one screen of the display device 7. That is, this is a method of displaying angle video information to be displayed on the display screen using the PinP function. As a result, the user can confirm the angle video information at a glance, and since it is the angle video information, the user can clearly know the video content, so that the angle video information to be selected can be selected easily and quickly. Since the PinP function only needs to be operated by a conventional method, detailed description thereof is omitted here.

  Here, the recording destination of the angle video information selected by the user may be directly recorded on the RE layer of the optical disc 100 or may be once recorded on the memory 5 of the optical disc apparatus 1 and later recorded on the RE layer of the optical disc 100. May be. However, when the angle video information is recorded in the memory 5 and the case where the angle video information is recorded in the RE layer of the optical disc 100, the angle video information is reproduced by the faster processing speed when the angle video information is recorded in the memory 5. Since recording is possible almost simultaneously with the selection, the load on the optical disc apparatus 1 can be reduced when a plurality of angle video information is recorded.

  Further, as a display method of the multi-angle video information, there is a method of displaying the angle video attribute information on the screen instead of the angle video information itself. Specifically, it is a method of displaying the relative position of the shooting target and each angle, or displaying the contents of the change in a drawing or graph when the shooting target or the like changes with time. . These drawings, graphs, and the like may be recorded in advance on the RE layer of the optical disc 100 by, for example, a disc supplier or video provider, and the video display control unit when the user selects multi-angle video information desired to be viewed. 25 may be displayed on the display screen, and the selection request unit 26 may cause the user to select desired multi-angle video information.

  Specific examples thereof will be described below. FIG. 6 is a diagram illustrating an example of multi-angle video attribute information displayed on the display device 7.

  First, the figure will be described. FIG. 6A shows an example in which angle video attribute information is displayed for each photographed angle.

  For example, in FIG. 5, it is assumed that the target photographing object of the multi-angle video information is indicated by A to D. A to D may be any target photographed object, for example, a person, an animal, a plant, an object, or a landscape.

  At this time, angles 1 to 3 include angle video information related to A to D, and angle 4 includes only angle video information related to A. More specifically, for example, the angle 1 includes angle video information of a subject to be photographed such as C → A → B → D → B → A → D → B → C → A → D in order of shooting time. ing. As a result, the user can check the display screen of the display device 7 to know which of the photographing objects of angle 1 is A to D, and one or a plurality of angle videos desired to be viewed. Information can be easily selected. The selection method may be, for example, a method of clicking those areas when viewing the first “C → A → B” of the angle 1. Alternatively, a method such as pressing a number button on the remote control may be used.

  In the figure, the angle video information is divided for each angle. However, the multi-angle video information may be displayed by a method for dividing the video information for each shooting time. Further, although A to D are expressed by different colors (patterns) in the same figure, they may be expressed by angle video attribute information such as characters instead of colors (patterns).

  Next, FIG. 6B will be described. This figure shows the direction of the shot angle on a photograph or drawing of the shooting location. In the figure, the shooting location is a stage, and six angles taken are displayed on a photograph (drawing) of the stage.

  At this time, if the angle desired to be viewed is angle 1, the user selects angle video information included in angle 1 by clicking the area indicating angle 1 or pressing a numeric button on the remote controller. be able to. Although not shown, for example, when an area showing angle 1 is clicked, a screen showing a plurality of angle video attribute information included in angle 1 (for example, display of angle 1 in FIG. 6A) appears. You may do it.

  Through the above operation, the user can check the shooting location and the shot angle in association with each other, and then select the angle that the user desires to view.

  Next, FIG. 6C will be described. This figure shows the direction of the angle taken and the shooting range on a photograph or drawing of the shooting location. In the figure, the shooting location is a baseball field, and four angles taken on a photograph (drawing) of the baseball field are shown.

  At this time, if the angle desired to be viewed is Angle 3, the user can select the angle video information included in Angle 3 by clicking on the area indicating Angle 3. Note that if the shooting range appears on the screen by moving a pointer or the like over the area indicating the angle 3, the user can be notified of the shooting range of the angle 3 (in FIG. 6C, the angle is displayed). 3 is shown). As a result, when the user wants to view an image in a predetermined shooting range, the user can easily check which of the angle 1 to angle 4 includes the shooting range.

  Heretofore, various display methods of multi-angle video attribute information have been illustrated with reference to FIGS. However, the display method of multi-angle video information is not limited to the above three, and can be displayed by various methods and combinations thereof. In addition to displaying the multi-angle video information, the multi-angle video attribute information may be displayed.

By the above method, the user can easily select an angle focusing on an object such as a favorite person (singer / actor / player / sports player) or an object (sports equipment such as a musical instrument / ball) or a favorite angle. You can select and enjoy the video.
3-3-2. Selection of Angle Video Information by User and Recording of Selection Results Next, an example of an operation for recording the selection results of angle video information will be described with reference to FIG.
3-3-2-1. Selecting video data itself First, the case of using angle video information itself as copy information will be described.

  FIG. 7 is a flowchart for explaining the operation of selecting angle video information and recording the selection result on the RE layer of the optical disc 100 via the memory 5 or directly.

  First, in S30, the user selects one or a plurality of angle video information desired to be viewed from the multi-angle video information or the angle video attribute information displayed by the video display control unit 25.

  Next, in S32, if the recording destination of the selection result in S30 is the RE layer (or R layer is acceptable) of the optical disc 100, the process proceeds to S36 (YES in S32). On the other hand, if the recording destination of the selection result in S30 is the memory 5, the process proceeds to S34 (NO in S32). It should be noted that either the RE layer of the optical disc 100 or the memory 5 of the optical disc apparatus 1 may be the recording destination of the selection result. However, if the processing speed of the optical disc apparatus 1 is limited by the display method or the like, the memory 5 Recording is faster.

  S34 corresponds to the case where the recording destination of the selection result in S30 is the memory 5 of the optical disc apparatus 1. In this case, the processing speed of the recording operation is fast, and the recording operation is recorded in the memory 5 from the selection start position almost simultaneously with the selection of the angle video information.

  On the other hand, S36 corresponds to the case where the recording destination of the selection result in S30 is the RE layer of the optical disc 100. In this case, since the optical pickup 12 has to perform the reproduction of the ROM layer and the recording to the RE layer in parallel, it follows the recording from the reproduction start position. That is, a time lag occurs between the reproduction operation and the recording operation.

  In S38, after the recording of the selection results in S34 and S36 is completed or during the recording operation, it is confirmed to the user whether there is angle video information to be further selected. For this confirmation, for example, the video display control unit displays a message such as “Click here if there is no more angle video information to be selected” on the display screen of the display device 7, and there is no angle video information to be selected. In such a case, the user may perform the above-described click, whereby the selection operation is completed, and in other cases, the selection operation is continued.

  If there is further angle video information to be selected, the process proceeds to S40 (YES in S38), and if there is no angle video information to be selected, the process proceeds to S42 (NO in S38).

  In S40, the selection switching time is corrected and recorded. That is, the timing at which the user issues a selection instruction by clicking or a button is actually after the video is switched, but this is automatically corrected. The selection switching time may be determined using a GOP (Group Of Pictures) boundary or a PTS (Presentation Time Stamp) value.

  S42 corresponds to the case where there is no other angle video information to be selected in S38. At this time, the process proceeds from S38 to S42 by clicking on the corresponding part in accordance with the above-mentioned message “Click here if there is no further angle video information to be selected”.

  When the process proceeds to S42, the video display control unit 25 ends the display of the angle video information on the display device 7, and the process proceeds to S44.

  In S44, item information different from the angle video information recorded in S34 and S36, for example, information indicating a selection result such as a user name and a selection date is recorded by the selected video recording control unit 27. When the recording destination is the memory 5, an operation for recording these in the RE layer is also performed.

  When the recording of the selection result is finished in S44, the process proceeds to S46, and all the selection operations of the angle video information are finished.

As described above, when the optical disc 100 is inserted into another optical disc apparatus 1, it is selected in the optical disc apparatus 1 and recorded in the RE layer without requiring the user to select the angle video information again from the multi-angle video information. The selected single angle video information (selection result) can be viewed by the user. Further, since the angle video information itself is recorded in the RE layer, even when the other optical disc apparatus 1 does not support the multi-angle function, the user can view the selected single angle video information (selection result). be able to.
3-3-2-2. Selecting Playlist Next, a case where a playlist of angle video information is recorded in the RE layer will be described. In this case, the ROM layer management information is used as copy information.

  The playlist is one piece of file management information, and is a list of the playback order of the angle video information recorded in the ROM layer of the optical disc 100 according to the user's preference. For example, since a list can be created for each title and shooting target, by using a playlist, the user can immediately play a video that the user wants to view based on the title and shooting target.

  When the playlist of the angle video information is used as copy information, the angle video information selected by the user is recognized, for example, in the section (IN point, OUT point) corresponding to the information, and this is temporarily stored in the memory 5. The data is recorded and later recorded on the RE layer of the optical disc 100 or directly on the RE layer of the optical disc 100.

  Even in this case, it is preferable to record after correcting the selection switching time. That is, the timing at which the user issues a selection instruction by clicking or a button is actually after the video is switched, but this is automatically corrected. The selection switching time may be determined using a GOP (Group Of Pictures) boundary or a PTS (Presentation Time Stamp) value, and the corrected IN point and OUT point may be recorded.

  As described above, when the optical disc 100 is inserted into another optical disc apparatus 1, it is selected in the optical disc apparatus 1 in the RE layer without requesting the user to select single angle video information from the multi-angle video information again. The recorded selected single-angle video information (selection result) can be viewed by the user. Furthermore, since the RE layer is recorded with a playlist of angle video information recorded in the ROM layer, the capacity can be reduced and many selection results can be recorded. Further, the free space can be used when recording other information such as version upgrade information.

  When reproducing single-angle video information selected by the user, a playlist is first read, and the ROM layer file management information recorded (copied) in the RE layer is read from the reproduction instruction. You can see which position (address) should be played. That is, the file management information (copy information) of the ROM layer and the file management information (playlist) of the RE layer are centrally managed, the number of interlayer jumps can be reduced, and the possibility of failure can be reduced.

  Further, if the file management information of the ROM layer is recorded on the outer peripheral side from the start position of the file management information of the RE layer, the playlist as the user's instruction is read first. Accordingly, after the playlist is read, the file management information of the ROM layer is read, and the reading operation proceeds from the inner circumference side to the outer circumference side of the optical disc 100. Therefore, a simple operation can be performed. be able to. In other words, it is not necessary to record information indicating the RE layer read instruction before the area where the file management information of the ROM layer is recorded, and it is unnecessary to read all the file management information of the ROM layer every time. No need for correct operation.

[Effects of this embodiment]
Next, effects of the optical disc device 1 and the optical disc 100 according to the present embodiment will be described.

  The optical disc apparatus 1 includes a ROM layer that can only read information, and an RE layer or an R layer (hereinafter, only the RE layer is described for convenience) in which information can be additionally recorded or information can be rewritten. An optical disc apparatus 1 that records or reproduces information on an optical disc 100 that is provided, and that is read by a video information reading unit 24 that reads registration information that is information recorded in a ROM layer, and read by the video information reading unit 24 And a selection video recording control unit 27 that records at least a part of the registration information on the outer periphery side of the recording start position of the file management information for managing the file recorded in the RE layer. .

  The optical disc 100 is an optical disc 100 having a ROM layer that can only read information and an RE layer that can additionally record information or rewrite information, and is recorded in the ROM layer. At least a part of the registration information, which is the recorded information, is recorded on the outer peripheral side of the recording start position of the file management information for managing the file recorded in the RE layer.

  Also, the control method of the optical disc apparatus 1 is such that information is recorded on the optical disc 100 provided with a ROM layer that can only read information and an RE layer that can additionally record information or rewrite information. A method of controlling an optical disc apparatus 1 that performs recording or reproduction, a reading step of reading registration information that is information recorded in a ROM layer, and at least part of the registration information read in the reading step And a recording control step of recording on the outer periphery side of the recording start position of the file management information for managing the file recorded in the layer.

  An optical disc 100 inserted into the optical disc apparatus 1 includes a ROM layer and an RE layer. The ROM layer is an information recording layer that can only read information, and the RE layer can additionally record information or record information. The information recording layer can be rewritten. In the optical disc apparatus 1, it is preferable that the video information reading unit 24 reads registration information recorded in the ROM layer, and the selected video recording control unit 27 records at least a part of the registration information in the RE layer.

  Therefore, at least a part of the registration information recorded in the RE layer (hereinafter, at least a part of the registration information recorded in the RE layer is referred to as “copy information”) only by the reading operation to the RE layer. This eliminates the need for a read operation to the ROM layer. Accordingly, it is not necessary to jump between the ROM layer and the RE layer to read the copy information from the ROM layer, and the processing speed of the optical disc apparatus 1 can be increased.

  Furthermore, in the optical disc apparatus 1, the copy information is preferably recorded on the outer peripheral side of the recording start position of the file management information for managing the file recorded in the RE layer.

  Therefore, when the optical disc 100 is inserted into the optical disc apparatus 1, the file management information of the RE layer is first read. Here, since file management information generally records user instructions and the like, it is only necessary to read other information based on the instructions and the like, and various information recorded in the ROM layer and RE layer. Substantial centralized management is possible. Since the file management information in which user instructions are recorded is read before the copy information, a reduction in processing speed and power consumption due to useless operations caused by reading unnecessary copy information. The problems of Patent Documents 1 and 3 such as an increase in Further, since it is not necessary to record the registration information in the memory on the optical disc apparatus 1 side, unified management of information can be realized on the optical disc 100 side, which cannot be solved by the techniques of Patent Documents 4 and 5.

  For these reasons, in the optical disc apparatus 1, the processing speed of the apparatus itself can be increased, and further, the operation of reading the copy information recorded in the RE layer from the ROM layer can be omitted, so the number of operations is reduced. As a result, the frequency of failures or the like occurring in the optical disc apparatus 1 can be suppressed.

  In addition, the copy information is recorded in the RE layer of the optical disc 100, not in the memory on the optical disc apparatus 1 side. Therefore, since the copy information is recorded in the RE layer when the optical disc 100 is taken out from the optical disc apparatus 1, the information recorded in the RE layer is used even when the optical disc 100 is used in another optical disc apparatus 1. It is possible to read the copy information originally recorded in the ROM layer only by reading. As a result, the reading operation to the ROM layer can be omitted also in the other optical disc apparatuses 1, so that the processing speed on the optical disc apparatus 1 side can be increased.

  Further, when updating (latest) information is acquired for the purpose of improving the security of the OS, applications, etc., or for the purpose of upgrading to a version that is easier to use, additional information is recorded when the updated information is recorded on the optical disc 100. Update information is recorded in the RE layer where information can be rewritten. Therefore, since the copy information is recorded in the RE layer, there is an effect that the copy information, update information, and the like can be managed in the RE layer in an integrated manner. As a result, there is no need to record copy information, update information, or the like on the recording medium on the optical disc apparatus 1 side, and unified management of information on the optical disc 100 side, which cannot be solved by Patent Documents 4 and 5, can be realized. .

  Furthermore, in the optical disc apparatus 1, the registration information preferably includes file management information recorded in the ROM layer. The file management information recorded in the ROM layer can be read out only by the information reading operation to the RE layer. That is, the operation for reading the file management information from the ROM layer and the processing time required for the operation can be reduced.

  The file management information is information for managing files recorded on the optical disc 100. The RE layer is an information recording layer in which information can be additionally recorded or information can be rewritten, and update information and new information (file) are additionally recorded in the RE layer.

  Therefore, if the file management information is recorded in the RE layer, the file management information can be updated, and the user can easily manage the files recorded on the optical disc 100.

  Furthermore, in the optical disc apparatus 1, the registration information preferably includes an index of registration information.

  In general, an index refers to an index, a table, a heading, or the like indicating which information is present in order to improve information (data) search speed.

  Accordingly, since the index of registration information is recorded in the RE layer, the index of registration information can be confirmed only by the read operation to the RE layer.

  Therefore, the user can effectively search the registration information recorded in the ROM layer.

  Further, in the optical disc apparatus 1, the registration information includes multi-angle video information that is information about multi-angle video shot from a plurality of angles, and the multi-angle video information is information about single-angle video shot from one angle. A single-angle video information for each of a plurality of angles, a video display control unit 25 that causes the display device 7 to display at least part of the multi-angle video information read by the video information reading unit 24, and video display control A selection request unit 26 that allows the user to select one or a plurality of single-angle video information desired to be viewed from the multi-angle video information displayed by the unit 25. The selection video recording control unit 27 includes the selection request unit 26. One or more single-angle video information selected by the user It is preferable to record the RE layer as 択済 single angle video information.

  The video display control unit 25 causes the display device 7 to display at least a part of the multi-angle video information read by the video information reading unit 24. Then, the selection request unit 26 causes the user to select one or a plurality of single-angle video information desired to be viewed from at least a part of the multi-angle video information displayed on the display device 7. In addition, the selected video recording control unit 27 causes the RE layer to record one or more pieces of single angle video information that the selection request unit 26 has selected by the user. As a result, one or more pieces of single-angle video information that the user desires to view are recorded in the RE layer as selected single-angle video information.

  Therefore, when the optical disc 100 is inserted into another optical disc apparatus, the selected single angle video selected in the optical disc apparatus 1 and recorded in the RE layer without requiring the user to select the single angle video information again. Information can be viewed by the user.

  As described above, the user can be provided with the optical disc device 1 having excellent convenience.

  Further, in the optical disc apparatus 1, the selected single angle video information is preferably a playlist in which one or a plurality of single angle video information is listed.

  The user can view the selected single-angle video information recorded in the RE layer without requiring the user to select the single-angle video information again from the multi-angle video information. Moreover, since the selected single-angle video information is recorded as a list of playlists, the required recording capacity is small, and a large amount of selected single-angle video information can be recorded in the RE layer. Become. The vacant recording capacity can be used for recording upgrade information and the like.

  The playlist is one piece of file management information, and is a list of the playback order of the angle video information recorded in the ROM layer according to the user's preference. For example, since a list can be created for each title and shooting target, by using a playlist, the user can immediately reproduce information (video information or the like) that he / she wants to view based on the title or shooting target. .

  Further, in the optical disc apparatus 1, it is preferable that the single angle video information displayed by the video display control unit 25 includes single angle video attribute information indicating an attribute of the single angle video corresponding to the single angle video information.

  The display device 7 displays single angle video attribute information. The single-angle video attribute information includes, for example, the position of the captured angle, the distance from the object to be imaged, the photographer, and the shooting date and time.

  Accordingly, the user can select one or a plurality of pieces of single-angle video information desired to be viewed, not the actual single-angle video itself, based on the single-angle video attribute information. Can end.

  Further, since the single-angle video attribute information displayed on the display device 7 has a smaller capacity than the single-angle video itself, the load on the optical disk device 1 when performing processing for displaying the single-angle video attribute information on the display device 7 Can be reduced, and therefore the processing speed can be increased.

  In addition, since it is not necessary to increase the capacity of a high-speed CPU or memory, it is possible to prevent the optical disk device 1 from becoming complicated and expensive.

  Furthermore, in the optical disc apparatus 1, it is preferable that the selected video recording control unit 27 records the single angle video and the single angle video attribute information related to the single angle video in the RE layer in association with each other.

  When playing back one or more pieces of single-angle video information recorded in the RE layer, attribute information (position of the shot angle, shooting object, etc.) corresponding to the single-angle video can also be displayed. By confirming the attribute information, the user can know the position of the photographed angle, the photographing object, and the like, and can accurately grasp the details of the reproduced single angle video.

  Furthermore, in the optical disc apparatus 1, the selected video recording control unit 27 preferably records one or more pieces of single angle video information on the RE layer in the order of the time when the single angle video was shot.

  If one or more pieces of single-angle video information are recorded in the RE layer in the order of the time when the single-angle video was taken, the optical information can be reproduced when reproducing one or more pieces of single-angle video information in the order of the taken time. There is an effect that the moving distance of the pickup 12 can be reduced, and thereby the processing speed of the reproduction process can be increased.

  Furthermore, in the optical disc apparatus 1, the video display control unit 25 preferably displays all of the multi-angle video information on one screen of the display device 7.

  Since the multi-angle video information is displayed on one screen of the display device 7, the user can confirm all the single-angle video information at a glance and can easily and quickly select the single-angle video information to be selected. .

  Further, in the optical disc apparatus 1, a plurality of single angle video information selected by the user by the selection requesting unit 26 is continuously played back, and the playback order is between two adjacent single angle video information. It is preferable to include a video insertion unit 28 that inserts a connection image for filling the discontinuity when reproduction time discontinuity occurs.

  In the case where two single-angle video information that are adjacent to each other in the order of reproduction and the single-angle video information photographed at different angles and at different times are continuously reproduced, the reproduction time of the two single-angle video information Discontinuity may occur. In such a case, unnaturalness may occur in the connection between two pieces of single-angle video information due to the discontinuity such as a display screen in which nothing is displayed.

  At this time, in the optical disc apparatus 1, the video insertion unit 28 inserts a connection image for filling discontinuity between two pieces of single-angle video information. As a result, it is possible to reduce the unnaturalness that has occurred in the connection between two pieces of single-angle video information.

  Note that the video insertion unit 28 is a known technique such as a morphing technique for complementing and creating a video while being deformed by a computer, or a scene change technique for automatically generating a connected image by detecting a change in luminance or color difference. It is possible to apply.

  Furthermore, in the optical disc apparatus 1, the connection image is preferably recorded in the ROM layer.

  Since a connection image suitable for single-angle video information recorded in the ROM layer can be prepared in advance, the user can view the single-angle video information without a sense of incongruity. Furthermore, since the connection image is recorded in the ROM layer, the user can save the trouble of acquiring the connection image from the outside.

  Furthermore, in the optical disc apparatus 1, the connection image is acquired via a network connected to the outside, and the selected video recording control unit 27 preferably records the connection image on the RE layer.

  Since the connection image is acquired from the outside, the user can acquire more types of connection images. Further, since the acquired connection image is recorded in the RE layer, it is possible to accumulate connection images that match the user's preference in the RE layer.

  Furthermore, in the optical disc apparatus 1, one or a plurality of single angles desired to be viewed from the selected single-angle video information selected by the user by the selection request unit 26 or the multi-angle video information displayed by the video display control unit 25. When the selection example for selecting the angle video information is recorded in the RE layer, the video display control unit 25 selects the selection result information that is a result of the selection request unit 26 causing the user to select, or the selection result information. It is preferable to display an example on the display device 7.

  Since it is possible to know the past selection results or the presence and content of pre-recorded selection examples, select the selection results themselves, or refer to the selection results and newly view single-angle video information that you want to view. Can be selected.

  Further, in the optical disc apparatus 1, a selection example for selecting one or a plurality of single-angle video information desired to be viewed from the multi-angle video information displayed by the video display control unit 25, or the selection request unit 26 allows the user to select. The selected single-angle video information is recorded on the optical disc 100, and the video display control unit 25, together with at least a part of the multi-angle video information read by the video information reading unit 24, selects examples or selected single angles. It is preferable to display the video information on the display device 7.

  The selected example or selected single-angle video information is displayed on the display device 7 together with at least a part of the multi-angle video information read by the video information reading unit 24. Therefore, the user can know what selection example or selected single-angle video information is being viewed.

  Further, in the optical disc 100, it is preferable that one or more pieces of single angle video information are recorded in the RE layer in order of the time when the single angle video is reproduced.

  When one or a plurality of single angle video information is recorded in the RE layer in the order in which the single angle video is reproduced, the one or a plurality of single angle video information is reproduced in the order of the reproduction time. There is an effect that the moving distance of the optical pickup 12 can be reduced, and thereby the processing speed of the reproduction process can be increased.

  Furthermore, in the optical disc 100, it is preferable that the multi-angle video information is recorded on the ROM layer in the order of playback time.

  When the optical disc apparatus 1 into which the optical disc 100 is inserted displays multi-angle video information by the PinP function and allows the user to select desired multi-angle video information, the optical pickup 12 is operated from the inner periphery to the outer periphery. Since there is no need to reciprocate, useless operation can be omitted.

  Furthermore, in the optical disc 100, it is preferable that multi-angle video information is recorded in the ROM layer for each shot angle.

  Since one or a plurality of single-angle video information is recorded in the ROM layer for each photographed angle, for example, when a chapter number is assigned for each angle, the chapter number and the angle number can be matched. It is possible to realize a configuration such as. Then, the operation required when the optical disc apparatus 1 displays multi-angle video information for the user to select or when the optical disc apparatus 1 records the selection result in the RE layer can be facilitated.

  Furthermore, in the optical disc 100, when the selected single-angle video information is reproduced, it is preferable that reproduction order information, which is information indicating the reproduction order, is recorded in the ROM layer.

  The reproduction order information is, for example, information for instructing to reproduce the single angle video in the order of the shooting times, or information for instructing that the single angle video is reproduced for each shot angle. is there. Such playback order information may be recorded in advance in the ROM layer by a disk supplier (manufacturer) or a video provider, and the user does not have to select the playback order by himself / herself. Based on the single angle video.

  The optical disc apparatus 1 may be realized by a computer. In this case, the control program for the optical disc apparatus 1 that causes the optical disc apparatus 1 to be realized by the computer by operating the computer as each means, and the program recorded there Computer-readable recording media are also within the scope of the present invention.

[Another expression of the present invention]
The present invention can also be expressed as follows.

  The optical disc according to the present invention has a rewrite-inhibited area (ROM layer) in which information is recorded and a rewritable area (R layer or RE layer), and the file management information in the rewrite-inhibited area is rewritten as a rewrite-inhibited area. The configuration may be recorded in the possible area. Note that the “file management information” here is not physical, but software that recognizes the file structure.

  With the configuration described above, the information recorded in the entire file system and the ROM layer can be acquired simply by reading the information recorded in the RE layer. In particular, the above configuration is useful when reading the file management area from the RE layer at the time when the optical disk is inserted. In addition, since management information (for example, a playlist) originally written in the ROM layer is recorded in the RE layer, it can be sequentially updated to the latest information. For example, when information of 1 to n is recorded in the ROM layer and n + 1 to N is recorded in the RE layer, these relationships must be recognized in any layer. In this respect, the file management information of the ROM layer and the RE layer can be centrally managed in the RE layer by rewriting the information recorded in the RE layer.

  Further, the optical disc according to the present invention may have a configuration in which multi-angle video information taken from a plurality of angles is recorded in the rewrite prohibition area.

  With the above configuration, the content recorded in the ROM layer can be recognized as a multi-angle video only by reading the RE layer. In addition, when information related to the ROM layer such as a playlist is recorded in the RE layer, the relationship between the recorded contents of the RE layer and the ROM layer can be known only by reading the RE layer.

  Furthermore, when recording a playlist in the RE layer, it is not necessary to seek the pickup up to the top of the ROM layer. Therefore, in the case of a partial ROM layer, the seek distance is shortened, and in the case of two layers (combination disc), it is not necessary to perform an interlayer jump. Therefore, the processing speed can be increased, and the probability that the recording / reproducing apparatus will malfunction and fail can be reduced.

  In addition, the optical disc according to the present invention may have a configuration in which videos taken from different angles with respect to the address of the optical disc are sequentially recorded for each specific time unit.

  Specifically, on the optical disc, a captured video angle 1-2-3 at time T1,... A captured video angle 1-2-3 at time T2, are recorded. As a result, in the case of displaying with the all-angle video PinP function for the user to select, since the moving distance of the pickup is small, the processing speed is increased (processing capacity is increased). .

  Further, the optical disc according to the present invention may have a configuration in which videos taken from different angles with respect to the address of the recording medium are sequentially recorded for each angle.

  Specifically, all information on angle 1 → all information on angle 2 → all information on angle 3 is recorded on the optical disc.
