  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram illustrating a configuration example of the recording / reproducing apparatus 1.

  The controller 21 develops and executes a navigation program (described later) stored in the local storage 24 in the memory 23 or controls the optical disk drive 22 to read out the navigation program recorded on the optical disk 11 and By expanding and executing the program 23, the playback operation of the optical disk 11 mounted on the recording / playback apparatus 1 is controlled. The controller 21 controls acquisition of an application program or navigation program via the Internet interface 25 or the removable medium 28, stores the acquired application program or navigation program in the local storage 24, and also stores the memory 23. Can be deployed and executed.

  Further, the controller 21 can execute a navigation program for reproducing information recorded on the optical disc 1 to be mounted, and a resident application program that can be executed in conjunction with the navigation program. At least a part of each of the navigation program and the application program can be operated on a multi-platform by implementing a virtual machine such as JAVA (registered trademark).

  In addition, the controller 21 can operate both the application program stored in the local storage 24 or the memory 23 and the navigation program recorded in the optical disc 11 or the local storage 24 on the same virtual machine. In the case where the inter-application communication function is provided, the operation of the recording / reproducing apparatus 1 can be controlled by developing these in the memory 23 and operating them in conjunction with each other.

  Here, the application program is a program for causing the recording / reproducing apparatus 1 to execute a process that is not directly related to the control of the reproduction of the content recorded on the optical disc 11, and in conjunction with the navigation program or It is designed to be able to operate independently of the navigation program.

  The optical disk drive 22 reads data from the optical disk 11 according to control by the controller 21, and outputs the read data to the controller 21, the memory 23, or the transcoder 26, or the memory 23, the local storage 24, or the transcoder 26. The signal supplied from is recorded on the mounted optical disk 11. When the information read from the optical disc 11 is a navigation program or a PlayList, the information read by the optical disc drive 22 is output to the controller 21 or the memory 23. When the information read from the optical disk 11 is an AV stream or text data, the information read by the optical disk drive 22 is output to the transcoder 26.

  FIG. 2 is a diagram showing an example of an application format of the optical disc 11 mounted on the recording / reproducing apparatus 1. In addition to the optical disk 11, the recording medium may be, for example, a magnetic disk or a semiconductor memory.

  The application format has two layers, PlayList and Clip, for managing AV (Audio Visual) streams. Here, a pair of one AV stream or text data and Clip Information which is information accompanying the AV stream or text data is considered as one object, and these are collectively referred to as Clip. Hereinafter, an AV stream data file is referred to as an AV stream file. A data file of Clip Information is referred to as a Clip Information file.

  In general, a file used in a computer or the like is handled as a byte string, but the content of an AV stream file is expanded on the time axis, and an access point of a clip is mainly designated by a PlayList with a time stamp.

  When the access point in the Clip is indicated by the PlayList with a time stamp, the Clip Information file is used to find address information to start decoding in the AV stream file from the time stamp.

  The PlayList is a set of information indicating the playback section of the AV stream. Information indicating one playback section in an AV stream is called PlayItem, and PlayItem is represented by a pair of IN point (playback start point) and OUT point (playback end point) of the playback section on the time axis. Therefore, the PlayList is composed of one or a plurality of PlayItems as shown in FIG.

  In FIG. 2, the first PlayList shown first from the left is composed of two PlayItems, and the first PlayList and the second half of the AV stream included in the first Clip shown on the left side by the two PlayItems. Each part is referenced. Also, the second PlayList shown second from the left is composed of one PlayItem, so that the entire AV stream included in the second Clip shown on the right is referred to. Furthermore, the third PlayList illustrated third from the left is composed of two PlayItems, and by the two PlayItems, a predetermined part of the AV stream included in the first Clip illustrated on the left side, and Reference is made to a predetermined portion of the AV stream included in the second Clip shown on the right side.

  The navigation program (Navigation program) is a program for causing the controller 21 to execute the function of controlling the playback order of the PlayList and the interactive playback of the PlayList. The navigation program also has a function of displaying a menu screen for the user to instruct execution of various reproductions. In addition, all or at least a part of the navigation program is described in a programming language that can be executed on a multi-platform by implementing a virtual machine, such as JAVA (registered trademark). Some of the functions of the navigation program other than those described in a programming language that can be executed on a multi-platform are not a multi-platform but a programming language that can be executed in a device-specific execution environment. It may be described.

  For example, when the navigation program is executed by the controller 21 and the first PlayItem included in the first PlayList illustrated first from the left in FIG. 2 is specified as information representing the playback position at that time, The first half portion of the AV stream included in the first Clip shown on the left side referenced by the PlayItem is played back.

  Further, in the PlayList described with reference to FIG. 2, in addition to the main path (Main Path) specified by PlayItem, the sub path specified by using a sub play item (Sub Play Item) as shown in FIG. (Sub path) information can also be included. When SubPlayItem is defined, for example, an independent data stream that is not multiplexed with a Clip (for example, MPEG2 transport stream) specified by PlayItem can be played back in synchronization with AV stream playback.

  For example, subtitle related information composed of a text subtitle file and a font file necessary for rendering, corresponding to the clip AV stream of the main path (Main Path) specified by PlayItem, and the playback section of the subtitle related information By preparing a SubPlayItem that specifies, the subtitles corresponding to the data described in the text subtitle file are displayed in the display font based on the font data described in the font file simultaneously with the playback of the Clip AV stream. It can be displayed on the device. Also, for example, by providing dubbed audio data in another language and SubPlayItem corresponding to dubbed audio data in correspondence with the Clip AV stream of the main path specified by PlayItem, playback of the Clip AV stream At the same time, dubbed voice data in other languages can be reproduced and output.

  Thus, the SubPlayItem and the corresponding data (clip) may be recorded on the optical disc 11 in advance, or may be downloaded from the server 3 via the network 2 as additional data (update data). Alternatively, it may be acquired using the removable medium 28. Details of downloading such additional data from the server 3 will be described later with reference to FIG.

  Returning again to the description of FIG.

  The memory 23 appropriately stores data and programs necessary for the controller 21 to execute various processes. The local storage 24 is composed of, for example, an HDD (Hard Disk Drive).

  The Internet interface 25 is connected to the network 2 by wire or wirelessly, communicates with the server 3 via the network 2 according to control from the controller 21, and transmits predetermined information to the server 3. The data downloaded from the server 3, the navigation program, the application program, and the like are supplied to the local storage 24. From the server 3, for example, data for updating the data (hereinafter also referred to as “main content”) recorded on the optical disc 11 mounted on the recording / reproducing apparatus 1 at that time, or an advertisement, Sub-contents such as a trailer (so-called trailer) are downloaded. The local storage 24 can record data downloaded from the server 3 via the network 2.

  Although only one server 3 is shown in FIG. 1, it goes without saying that there may be a plurality of servers that exchange information with the recording / reproducing apparatus 1 via the network 2. .

  The transcoder 26 decodes the AV stream or text data supplied from the optical disk drive 22 or the local storage 24, and outputs the obtained video signal and audio signal to an external display device. In the display device, based on the signal decoded by the transcoder 26, for example, the content recorded on the optical disc 11 (video display, audio output) is output. The transcoder 26 converts the AV stream or text data supplied from the optical disk drive 22 or the local storage 24 into a predetermined format, that is, executes a decoding process, and then encodes the AV stream or text data into the predetermined format. Then, it can be supplied again to the optical disk drive 22 and recorded on the loaded optical disk 11 (it goes without saying that the disk may be different from the optical disk 11 from which the re-encoded data is read). .

  The operation input unit 29 includes, for example, an input device such as a button, a key, a touch panel, a jog dial, and a mouse, and a receiving unit that receives a signal such as an infrared ray transmitted from a predetermined remote commander, and acquires a user operation input. To the controller 21.

  In addition, a drive 27 is connected to the controller 21 as necessary. For example, a magnetic disk (including a flexible disk), an optical disk (CD-ROM (Compact Disk-Read Only Memory), DVD) A removable medium 28 including a magneto-optical disk (including MD (registered trademark) (Mini-Disk)), a semiconductor memory, or the like.

  Next, a method for reproducing the data recorded on the optical disk 11 mounted on the recording / reproducing apparatus 1 and the data stored in the local storage 24 will be described.

  The recording / reproducing apparatus 1 includes a local storage 24 including an HDD (Hard Disk Drive). The recording / reproducing apparatus 1 is connected to the network 2 by wire or wireless, and can download data downloaded from the server 3 via the network 2 to the local storage 24. From the server 3, for example, data for updating a content such as a movie recorded on the optical disc 11 mounted on the recording / reproducing apparatus 1 at that time, or content (main content) such as a movie recorded on the optical disc 11 is updated. For example, sub-content such as commentary of directors and actors, advertisements, trailers, and the like can be downloaded.

  In a state where the downloaded data is recorded in the local storage 24, when the operation input unit 29 instructs the reproduction of the content recorded on the optical disc 11, the controller 21 displays the content recorded on the optical disc 11. And the content recorded in the local storage 24 are associated with each other, and the content reproduction process is executed.

  Here, a method for reproducing the content recorded on the optical disc 11 and the content recorded on the local storage 24 in association with each other will be described with reference to FIG.

  For example, it is assumed that the optical disk 11 is a medium sold as a package and a movie content is recorded. Further, it is assumed that only an English text subtitle file is recorded on the optical disc 11 as a subtitle data file that can be displayed superimposed on the movie content video.

  For example, in FIG. 4, the Clip1 AV stream recorded on the optical disc 11 and referred to by the PlayList PlayItem is a stream for displaying the video of the movie content and playing the corresponding audio. The subtitle related information 1 of Clip2 to be referred to is a text subtitle file for displaying English subtitles in conjunction with video display.

  In this state, when subtitles in a language different from English are displayed and movie contents recorded on the optical disc 11 are to be viewed, subtitle data in a language different from English is not recorded on the optical disc 11. The user cannot view the movie by displaying subtitle data in a language different from English in this state.

  Therefore, the user causes the recording / playback apparatus 1 to download a text subtitle file in a desired language of a movie recorded on the optical disc 11 from the server 3 via the network 2 (or obtain it using the removable medium 28). A state in which a text subtitle file, for example, in Arabic that has not been recorded in advance on the optical disc 11 has been downloaded (or copied from the removable medium 28 to the local storage 24) will be described.

  That is, when the user instructs to download an Arabic text subtitle file corresponding to the PlayList recorded in advance on the optical disc 11, the recording / playback apparatus 1 accesses the server 3 and records on the optical disc 11. A file prepared in the server 3 is downloaded as an update of the content that has been updated.

  In the example of FIG. 4, for example, a video clip and audio of movie content recorded in advance on the clip 3 and the optical disc 11 composed of an Arabic text subtitle file (subtitle-related information 2) and a clip information file associated therewith. In addition to Clip (AV stream data) and English text subtitle files, the PlayList file (Updated PlayList file) that can control the playback and display of the corresponding subtitle data of Clip 3 is compared with the one recorded on the optical disc 11 The updated new navigation program files are downloaded and recorded in the local storage 24.

  Note that, in the updated play list, SubPlayItem1 and SubPlayItem2 representing sub paths are added in addition to the PlayItem representing the main path. PlayItem of Updated PlayList refers to Clip1 including AV Stream recorded on optical disc 11, SubPlayItem1 refers to Clip2 including subtitle related information 1 recorded on optical disc 11, and SubPlayItem2 Refers to Clip3 including subtitle related information 2 that is an Arabic text subtitle file downloaded from the server 3 together with the updated play list.

  The new navigation program of FIG. 4 can specify SubPlayItem1 or SubPlayItem2 together with the PlayItem of the updated play list as a playback section. Thus, for example, the new navigation program is associated with the desired video and audio data in advance on the optical disc 11 in advance. Of the English subtitles defined by the recorded text subtitle file in English or the Arabic subtitles defined by the text subtitle file in Arabic not previously recorded on the optical disc 11, the subtitles in the language desired by the user Can be displayed.

  As described above, when the download from the server 3 (or the copy from the removable medium 28) is performed, the recording / playback apparatus 1 is not prepared in advance in the clip 2 that is an English text subtitle file and the optical disc 11. Any of Clip3 which is an Arabic text subtitle file can be reproduced and displayed as a subtitle of a movie. That is, the user views a movie with a desired language subtitle in English or Arabic by selecting a desired language from among the subtitle languages that can be displayed on the menu screen displayed on the display device. be able to.

  Similarly, the recording / playback apparatus 1 is a text subtitle for displaying subtitles in a language not prepared in advance on the optical disc 11 by downloading from the server 3 (or copying from the removable medium 28). In addition to adding files, for example, as described above, substreams such as audio stream files of dubbed audio in different languages, commentary of directors and actors for main contents such as movies, so-called trailers such as trailers or commercials, etc. Data files for display can be acquired and played back.

  Note that the AV stream recorded on the optical disc 11 has a structure of an MPEG2 (Moving Picture Experts Group 2) transport stream as shown in FIG. The MPEG2 transport stream is composed of an integer number of Aligned units. The size of the Aligned unit is 6144 bytes (2048 × 3 bytes), and starts from the first byte of the source packet. The source packet is 192 bytes long. One source packet is composed of a TP_extra_header and a transport packet. TP_extra_header is 4 bytes long, and the transport packet is 188 bytes long. One Aligned unit is composed of 32 source packets. Video stream and audio stream data are packetized into MPEG2 PES (Packetized Elementary Stream) packets, and PES packets are packetized into transport packets.

  Here, all navigation programs executed in the controller 21 and application programs that can be executed in conjunction with the navigation programs are described as being written using the JAVA (registered trademark) language. These programs can be operated on a virtual machine, such as C # or Visual Basic, that is, any programming language that can be operated on a multi-platform. It is feasible.

  That is, processing executed by a plurality of applications that can be executed in the recording / reproducing apparatus 1 is managed based on the control of a so-called application manager.

  Specifically, JVM (JAVA (registered trademark) Virtual Machine), which is software executed by converting JAVA (registered trademark) bytecode into native code of the platform, is used. Navigation programs and application programs, which are software developed by JAVA (registered trademark), have their own format independent of the platform (JAVA (registered trademark) bytecode) and cannot be executed as they are. For this reason, the JVM executes the navigation program and the application program while converting the JAVA (registered trademark) byte code into the native code in the recording / reproducing apparatus 1.

  A set of instructions and functions that can be used when developing a navigation program, which is software that runs on the JVM, or a set of rules that define the program procedures for using them is called an API library. The developer of the navigation program can create software that uses the function without programming it by simply calling the function of the API library according to the convention. As a specific example of the API, an API related to file access will be described later.

  The resident application program may realize a function not directly related to the reproduction process of the information recorded on the optical disc 11. That is, the resident application program is, for example, a program that controls recording of program content provided to the user via broadcast waves or a cable network, a web browser, a program that executes database processing, or a user operation A program for controlling the display of a display screen (so-called GUI) to assist input, an interface for transmitting / receiving information to / from a predetermined server via the network 2, or data on a recording medium such as a mounted optical disk Other than the program necessary for the reproduction process of the content data recorded on the mounted optical disk 11 or the download data stored in the local storage 24 in association with the optical disk 11.

  For example, the recording / reproducing apparatus 1 has a function of receiving a broadcast program, a function of changing a channel of a received broadcast program, a function of recording a received broadcast program, or a wide area network such as the Internet for web browsing. A navigation program if it has a function to perform data recording, an interface function for exchanging information with a predetermined server via the network 2, or a function to record data on a recording medium such as an optical disk mounted. It is possible to prepare an application program that can control these functions in conjunction with each other.

  When the application program and the navigation program operate in conjunction with each other, the navigation program detects the application program stored in the local storage 24 or the memory 23 and operates in conjunction with itself, and starts up. Or an application program can activate a navigation program corresponding to the optical disc 11 currently mounted on the recording / reproducing apparatus 1.

  Further, for example, the application program may be activated by a user operation input. Even in such a case, the application program can operate in conjunction with the navigation program. The application program includes, for example, one piece of identification information for identifying the optical disc 11 (for example, disc_id or content_id described later), identification information for identifying a content provider (for example, org_id described later), and the like. Or a plurality of them can be associated.

  An application program and a navigation program that run on the JVM can be configured as JAVA (registered trademark) Xlet, and communication between these applications is executed using IXC (Inter-Xlet Communication).

  Furthermore, communication between applications in a plurality of application programs operating on the JVM is also executed using IXC.

  Xlet is an application execution model that is specified by PBP (Personal basis Profile) and PP (Personal Profile) profiles. Xlet was originally defined in JAVA (registered trademark) TV, which is a JAVA (registered trademark) execution environment specification for TV set-top boxes. However, Xlet communication, that is, IXC specification was added, and CDC It is specified as an application model on (Connected Device configuration).

  The Xlet execution environment supports the simultaneous execution of multiple Xlets, but each Xlet uses an independent class loader and cannot directly reference other Xlets. IXC is defined to exchange information between multiple Xlets.

  FIG. 6 is a functional block diagram illustrating a functional configuration example realized when the navigation program is executed, among the functions of the controller 21.

  Each configuration of FIG. 6 is realized by the controller 21 executing a navigation program prepared in advance or recorded on the optical disc 11.

  The operation input acquisition unit 61 acquires a signal indicating an operation input from the user, which is input from the operation input unit 29, and outputs a signal indicating the operation input from the user as a menu screen display control unit 62 and a data transfer control unit 63. And output to a corresponding location in the local storage directory management unit 64 or the reproduction control unit 67.

  The menu screen display control unit 62 deletes the audio or subtitle language of the content recorded on the optical disc 11, the button operated by the user when selecting the video angle, the update file to be downloaded, and the like. A menu screen including buttons operated by a user when selecting a file is displayed on an external display device.

  The data transfer control unit 63 controls communication performed on the Internet interface 25 in FIG. 1 or information transfer with the removable medium 28 by the drive 27. For example, the data transfer control unit 63 controls transmission of predetermined information to the server 3. Further, the data transfer control unit 63 downloads and acquires the update file designated by the user from the server 3, and outputs the acquired file to the local storage directory management unit 64. In addition, the data transfer control unit 63 receives supply of information indicating a necessary file from a file system merge processing unit 66 described later, downloads the necessary file from the server 3, acquires the acquired file, and acquires the acquired file in the local storage. The data is output to the directory management unit 64.

  The local storage directory management unit 64 manages the directory of the local storage 24 and controls writing of data to the local storage 24, reading of data from the local storage 24, and deletion of data from the local storage 24. For example, the PlayList read from the local storage 24 under the control of the local storage directory management unit 64 is output to the memory 23, and the audio data and video data of the AV stream and the text of the text subtitle file read from the local storage 24 are read. The data is output to the transcoder 26. Further, when the file system merge processing unit 66 merges the file system of the optical disc 11 and the file system of the local storage 24 by the file system merge processing unit 66, the local storage directory management unit 64 displays information on the file system of the local storage 24 as a file system. The data is output to the merge processing unit 66.

  The optical disc directory management unit 65 detects and manages a directory on the optical disc 11 and controls reading of each data from the optical disc 11. The optical disc 11 is set with identification information such as organization_id (hereinafter also referred to as org_id) and disc_id, and, if necessary, content_id for identifying content. The org_id and disc_id (content_id as required) read from the optical disc 11 are output to the data transfer control unit 63 and the local storage directory management unit 64 under the control of the optical disc directory management unit 65. Also, the PlayList read from the optical disc 11 is output to the memory 23 under the control of the optical disc directory management unit 65, and the audio data and video data of the AV stream and the text data of the text subtitle file read from the optical disc are: It is output to the transcoder 26. In addition, when the file system merge processing unit 66 merges the file system of the optical disk 11 with the file system of the local storage 24, the optical disk directory management unit 65 performs file system merge processing on information related to the file system of the optical disk 11. The data is output to the unit 66. The org_id, disc_id, and content_id will be described later.

  The file system merge processing unit 66 merges the file system of the optical disk 11 supplied from the optical disk directory management unit 65 with the file system of the local storage 24 supplied from the local storage directory management unit 64 to create one virtual file. Generate the system. The file system merge processing unit 66 outputs the virtual file system generated by merging to the reproduction control unit 67.

  In addition, when some files recorded in the local storage 24 are deleted (erased, that is, data is deleted), the file system merge processing unit 66 deletes some of the files in the virtual file system. Whether or not a failure occurs in the file link structure (that is, the linkage of data for clip reproduction by PlayList based on the application format of the optical disc 11 as described with reference to FIGS. 2 to 4). If it is determined that a defect occurs in the file link structure in the virtual file system, a file necessary for resolving the defect is extracted, and information indicating the necessary file is supplied to the data transfer control unit 63 and necessary. Can download various files.

  Further, the file system merge processing unit 66 is not played back by any PlayList in the virtual file system, for example, by deleting some files recorded in the local storage 24 (not specified by all PlayLists). When a file is generated, the local storage directory management unit 64 can be instructed to delete such an unnecessary file.

  Note that the user may be able to set whether or not to delete unnecessary files that are generated when several files are deleted.

  The reproduction control unit 67 executes a navigation program specified by the virtual file system supplied from the file system merge processing unit 66, and controls the reproduction of content. Specifically, the playback control unit 67 refers to the PlayList supplied to and stored in the memory 23 and controls the local storage directory management unit 64 or the optical disc directory management unit 65 to control the optical disc 11 or the local storage 24. 1 is read out based on the virtual file system, and the audio data of the AV stream recorded on the optical disk, and if necessary, the text data of the text subtitle file are controlled based on the virtual file system to control the optical disc. 11 or audio data of the AV stream recorded in the local storage 24, video data, and, if necessary, text data of the text subtitle file is decoded (reproduced).

  Then, the application program linkage processing control unit 71 detects whether or not there is an application program that is executed in conjunction with itself when the navigation program is executed, and the application program that is executed in conjunction with itself is detected. If it exists, the IXC control unit 72 is used to exchange information with the application program and execute a predetermined operation.

  The IXC control unit 72 controls the above-described IXC and has an interface function between the navigation program and the application program. In other words, the IXC control unit 72 transmits the data or parameters obtained by the processing executed by the functions of the operation input acquisition unit 61 to the reproduction control unit 67 to the application program (specifically, binding to IxcRegistry). Control the reception of information from the application program (specifically, lookup to IxcRegistry). Further, the IXC control unit 72 also has an interface function between a plurality of application programs.

  The application program execution processing unit 73 controls execution of the application program.

  Next, using FIG. 7 to FIG. 16, the file system of the optical disc 11 performed by the file system merge processing unit 66 of the navigation program, downloaded from the server 3, copied from the removable medium 28, or optical disc The merging of file systems for managing data groups recorded in the local storage 24 by being copied from No. 11 will be described.

  For example, when the optical disc 11 is mounted on the recording / reproducing apparatus 1 or when the reproduction of the content recorded on the optical disc 11 is instructed, the file system merge is recorded on the optical disc 11 or the local storage 24. This is performed when data input / output is instructed, or when merge is instructed by the user.

  A virtual file system is defined as an upper layer of a native file system (file system of data actually recorded on the optical disc 11 or the local storage 24) possessed by the system of the recording / reproducing apparatus 1. That is, as shown in FIG. 7, new data is downloaded from the server 3 and recorded in the local storage 24, or processing for reproducing the data actually recorded on the optical disk 11 or the local storage 24 is executed. A navigation program or a user who handles the navigation program can recognize only a virtual file system that is an upper layer. In other words, the virtual file system is constructed to abstract the native file system and conceal the native structure such as the physical device and the operating system in the recording / reproducing apparatus 1.

  The role of the virtual file system is mainly to mount a file / directory in the physical device (the optical disk 11 or the local storage 24) to configure a virtual disk file system recognized by the user, and to perform navigation. To provide the program with a file access API to the constructed virtual disk.

  For example, when the user performs an operation input requesting access to any file recorded on the optical disc 11 or the local storage 24, only the virtual file system is included in the navigation program as shown in FIG. Can only recognize. The structure of the local file system # 1, the local file system # 2, or the file system in the optical disk 11 recorded in the optical disk 11 or the local storage 24, which is an actual physical device, includes a navigation program and a navigation program. It is hidden from the user who handles it, and is accessible via a virtual file system.

  In order to execute the file access request shown in FIG. 8, the navigation program of the recording / reproducing apparatus 1 calls a file input / output API (Application Programming Interface) provided by the virtual file system to physically store the disk drive. The data actually recorded on the optical disk 11 or the local storage 24 can be accessed without being conscious of the configuration or the software configuration of the file system. In other words, the API of the virtual file system actually calls the API of the native file system inside the recording / reproducing apparatus 1.

  The virtual file system provides various APIs, for example, open () to open the specified file, close () to close the specified file, seek () to set the reading or writing position of the specified file, specification APIs such as stat () for acquiring the status of the specified file, read () for reading the specified file, and write () for writing the specified file are provided. When the navigation program is executed (that is, when the function described with reference to FIG. 6 is realized), the playback control unit 67 is recorded on the optical disc 11 or the local storage 24 using these APIs. To operate the file.

  The virtual file system has a function of dividing and managing the disk area of the local storage 24. Of the disk area of the local storage 24, the storage area of the file group managed by the navigation program has a directory structure divided for each org_id as shown in FIG. 9, for example, and is a directory directly under the org_id. Below disc_id, a flexible file / directory structure can be configured by the content author (content provider). Where the data stored in the local storage 24 is arranged in the disk area of the local storage 24, that is, the file / directory structure of the file to be downloaded is the file management information (Manifest described later) included in the downloaded data. File).

  In the file / directory structure of the local storage 24, org_id that divides a directory is an identifier for use in constructing a virtual file system on the corresponding optical disc, and disc_id identifies each content associated with the same org_id. This identifier is used for constructing a virtual file system on the corresponding optical disc, similarly to org_id. org_id and disc_id are information included in file management information (manifest data described later) of data downloaded via the network 2 or detected from the optical disc 11 by the optical disc directory management unit 65.

  For example, the org_id may be given to each organization or group such as a content distributor (content author) or a content producer, or a plurality of these organizations or groups use one org_id. Alternatively, one organization or group may use a plurality of org_ids. In addition, disc_id is one associated with one optical disc 11 assuming that one content is recorded on one optical disc 11. For example, a plurality of contents are included in one optical disc 11. The disc_id may be associated with each of the recorded contents. In addition, when a plurality of contents are recorded on one optical disc 11, one disc_id is associated with one optical disc 11, and a content_id different from disc_id is associated with each of the plurality of contents. It is good. That is, content_id is an identifier for identifying content. Thus, no matter how org_id and disc_id are used, the virtual file system is constructed based on the respective ids. Details of the file management information (Manifest file) and org_id and disc_id will be described later with reference to FIG.

  On the other hand, the directory / file structure of the virtual disk accessible from the application follows the directory / file structure of the optical disk 11. That is, the file structure of data corresponding to org_id and disc_id or less is merged with the file structure of data recorded on the optical disc 11 with respect to the optical disc 11 mounted on the recording / reproducing apparatus 1, and the directory / file on the optical disc 11 is merged. A virtual file system of a virtual disk having a directory / file structure based on the structure is configured.

  In addition to the directory and file management mechanism, the virtual file system has a function of managing file management information, that is, a Manifest file described later, in units of discs. The purpose of the virtual file system to define the Manifest file field that is file management information as a kind of metadata for the file model of the native file system is actually recorded in the local storage 24 for the user. Instead of presenting the path or file name of the existing file, providing a name expressing the content content, preventing double updating of the same file in the download process, and the path name in the virtual file system, That is, there are three ways of defining a path name when reproducing the optical disc 11.

  The virtual file system provides two functions for managing metadata: a Manifest file and a metadata operation procedure. A Manifest file is a type of metadata that indicates various attributes of a downloaded file. Even if Manifest () is saved in units of the corresponding file, it is merged into one file and the identifier of the Manifest () section. The manifest_id (described later in FIG. 10) may be identified using a key. Regardless of the form, here it is collectively referred to as a Manifest file. The recording / reproducing apparatus 1 holding the file downloaded to the local storage 24 must hold the Manifest file. The Manifest file can also take a text representation in a tagged language represented by XML.

  FIG. 10 is a diagram illustrating the syntax of the Manifest file.

  manifest_id is the identifier of this Manifest () section.

  organization_id (org_id) is a field for designating an identifier used to construct a virtual file system on the corresponding optical disc. This identifier is determined by referring to the org_id field of the content distribution file, which will be described later with reference to FIG. 16, and the application program or user cannot freely set a value in this field.

  disc_id is a field for designating an identifier for uniquely identifying each optical disc or content associated with the same org_id. disc_id is also used to construct a virtual file system on the corresponding optical disc, similarly to org_id. This identifier is determined by referring to the disc_id field of the content distribution file, which will be described later with reference to FIG. 16, and the application program or the user cannot freely set a value in this field.

  Next, permission is a field for the content author to specify permission / authorization information such as whether to make the attribute visible to the user, invisible attribute, or whether to overwrite the file. . Note that the permission information may be described in any file other than the Manifest file, or may be configured as an independent file.

  FIG. 11 shows a list of values that can be specified for the permissions included in Manifest () of FIG.

  As shown in FIG. 11, when 0x00 is described in the 8-bit field of permission, the attribute of the file accompanied by this metadata is an invisible attribute to the user, and the 8-bit permission is set. When 0x01 is described in the field of, the attribute of the file accompanying this metadata is a visible attribute to the user, and when 0x02 is described in the 8-bit field of permission, The attribute of the file accompanying this metadata is an overwrite prohibition attribute.

  Src_file_name is information that can uniquely specify where the file is recorded in the directory structure in the file system of the storage area managed by the navigation program in the disk area of the local storage 24, that is, the local storage 24. This is a field for designating a “path name” representing a so-called path that specifies a file using the file position in the hierarchical structure of the file system. It is assumed that the name of the file or directory for expressing the path name is encoded according to the ISO / IEC 646 standard.

  dst_file_name is information that can uniquely specify where the file is recorded in the directory structure at the binding destination of the file stored in the local storage 24 in the virtual disk, that is, the file in the hierarchical structure of the virtual file system. This is a field for specifying a “path name” representing a so-called path that specifies a file using a position. It is assumed that the name of the file or directory for expressing the path name is encoded according to the ISO / IEC 646 standard.

  Note that the same name can be specified for src_file_name and dst_file_name.

  The credential describes information for checking the file access authority when the file specified in src_file_name is under a directory with a different org_id. As a result, in the local storage 24, it becomes possible to share content files among a plurality of directories under org_id.

  Next, a metadata operation procedure will be described.

  The virtual file system defines an API for reading the contents of Manifest () without exposing the file name, file position, physical structure, etc. of Manifest () to the navigation program or user.

  That is, a navigation program or a resident application program prepared in advance in the recording / playback apparatus 1 can indirectly access Manifest () by calling the following API.

getProperty
Argument 1:
String type data
Absolute path name of the file subject to metadata operations Argument 2:
String type data
Element name of metadata to be read
String type data
Metadata corresponding to the element specified in the argument Function:
Read metadata from Manifest ().

  Actually, the definition of detailed API such as type information must be changed depending on the programming language specification of the software execution environment of the recording / reproducing apparatus 1.

  FIG. 12 is a diagram illustrating an example of a file system of the optical disc 11. As shown in FIG. 12, the file system of the optical disc 11 has a directory structure.

  A directory in which the name “BDMV” is set is prepared under “root” of the optical disc 11, and a file in which the name “Info.bdmv” is set and a name “MovieObjects.bdmv” are provided in the directory. The set file is stored. Hereinafter, these files will be referred to as an Info file and a MovieObject file, respectively, as appropriate. As appropriate, each file is referred to by adding “file” to “file name”, or each directory is referred to by adding “directory” to “directory name”.

  The Info file includes information regarding a menu for playing the optical disc 11. The recording / reproducing apparatus 1 displays, for example, a reproduction menu screen including items such as reproducing all contents of the optical disc 11, reproducing only a specific chapter, repeating reproduction, and displaying an initial menu based on the Info file. Display on the display device. A MovieObject to be executed when each item is selected can be set in the Info file. When one item is selected from the playback menu screen by the user, the recording / playback apparatus 1 uses the MovieObject set in the Info file. Execute the command.

  The MovieObject file is a file including MovieObject. The MovieObject includes a command for controlling playback of the PlayList recorded on the optical disc 11, that is, a command issued by the navigation program. For example, the recording / playback apparatus 1 selects one of the MovieObjects recorded on the optical disc 11. The content recorded on the optical disc 11 can be played back by selecting and executing.

  Furthermore, MovieObject includes various commands necessary for executing processing in conjunction with an application program. Specifically, for example, a command for inquiring whether or not an application program executed in conjunction with the navigation program is installed in the recording / reproducing apparatus 1, and an application program executed in conjunction with the navigation program is recorded in the recording / reproducing apparatus 1. The MovieObject includes a command for starting the application program when it is installed.

  The BDMV directory also includes a directory with the name “BACKUP” (BACKUP directory), a directory with the name “PLAYLIST” (PLAYLIST directory), and a directory with the name “CLIPINF” (CLIPINF directory). , A directory (STREAM directory) in which the name “STREAM” is set, and a directory (AUXDATA directory) in which the name “AUXDATA” is set.

  In the BACKUP directory, files and data for backing up files and data recorded on the optical disc 11 are recorded.

  A PlayList file is stored in the PLAYLIST directory. As shown in the figure, each PlayList file is given a name obtained by adding an extension “.mpls” to a file name consisting of a 5-digit number.

  A Clip Information file is stored in the CLIPINF directory. Each Clip Information file is named by adding the extension “.clpi” to a file name consisting of five digits as shown in the figure.

  In the STREAM directory, a Clip AV stream file and a substream file are stored. Each stream file is given a name obtained by adding an extension “.m2ts” to a file name consisting of five digits as shown in the figure.

  The AUXDATA directory is not included in the Clip AV stream file or substream file, but is referred to from the Clip AV stream file or substream file, or data used independently of the Clip AV stream file or substream file. And other files are stored. In the example of FIG. 12, the AUXDATA directory stores a subtitle font file named “11111.otf” and a sound effect set with the name “sound.bdmv”.

  In the META (METADATA) directory, for example, content metadata including a title, a genre name, an actor name, a director name, a keyword, a story outline description, and connection information such as a URL of the server 3 are stored.

  Navigation programs are stored in the BDJO directory and the JAR directory.

  In addition, identifiers org_id and disc_id, and content_id as necessary, are recorded on the optical disc 11 as secure electronic data that cannot be rewritten by the user or physically by pits.

  FIG. 13 is a diagram showing an example of a file system of a storage area managed by the navigation program in the disk area of the local storage 24. As shown in FIG. 13, the file system of the local storage 24 also has a directory structure.

  A directory having at least one “org_id” name is prepared under “root” of the local storage 24, and at least one “disc_id” name is set under the “org_id” directory. A directory is provided. “Org_id” and “disc_id” are used to construct a virtual file system, and all “disc_id” included in “org_id” under “root” in the local storage 24 are distinguished from each other. As different as possible. The directory “disc_id” includes a Manifest file including a set of Manifest () sections or one Manifest () section. Other directory and file structures can be freely set by the content author. For example, the directory / file structure of the optical disk 11 described with reference to FIG. 13, the directory / file structure of the optical disc 11 described with reference to FIG. 12 may be completely different.

  For example, in FIG. 13, in addition to the Manifest file, a plurality of folders such as a “MainMovie” directory, a “SubTitle” directory, and an “AUXDATA” directory are set in the “disc_id” directory. It can contain folders or files.

  The directory / file structure of the local storage 24 shown in FIG. 13 is hidden from the navigation program executed in the recording / reproducing apparatus 1 or the user.

  For example, in the Manifest () section described with reference to FIG. 10, the path name “/MainMovie/movie01/main.r1.jp.mp2” is specified in the src_file_name field, and “/ STREAM / 01002. When the path name “m2ts” is designated, the downloaded data is stored in the main. directory in the movie01 directory in the MainMovie directory under the corresponding org_id and disc_id in the local storage 24, as shown in FIG. Although it is recorded with the file name r1.jp.mp2, in the virtual file system on the virtual disk, it is handled as a file with the file name 01002.m2ts in the STREAM directory.

  As described above, the content author specifies the path name in the local storage 24 in the src_file_name field of the Manifest () section of the downloaded file package, and specifies the path name of the virtual file system in the virtual disk in the dst_file_name field. can do. Therefore, if a path name adapted to the virtual file system in the virtual disk is set in the field of dst_file_name, the content author can use the file / directory under the disc_id of the data actually recorded in the local storage 24 of the recording / playback apparatus 1. The structure can be set freely, and new directories and files can be added to the area under disc_id.

  The synchronization (binding) method between the actual file system in the optical disk 11 and the local storage 24 and the file system of the virtual disk may be a so-called static binding method or a dynamic binding method. Define a new API (for example, update ()) to update the file system so that the virtual file system is updated when the API is explicitly called by a user operation or application program. May be.

  The static binding refers to the actual file system in the optical disk 11 and the local storage 24 at the time when the optical disk 11 is mounted on the recording / playback apparatus 1 or when the playback title is switched, and the directory of the virtual file system. / File structure mapping, and dynamic binding is to search for a necessary file when a file input / output request is issued.

  The directory / file structure of the virtual disk is preferably matched with the directory / file structure of the optical disk 11 as described above. The directory / file structure of the optical disc 11 is determined in advance by a standard or the like and cannot be changed in many cases, and the directory and file structure of the actual file system in the local storage 24 can be freely set by the content author. Is preferred. Therefore, if the directory / file structure of the virtual disk can be set based on the directory / file structure of the optical disk 11 that cannot be changed, the degree of freedom of data distributed by the content author is maintained. It is preferable because the reproduction process conforming to the standard such as the application format of the optical disc 11 can be executed.

  An example of the directory / file structure in the virtual disk is shown in FIG.

  In the directory / file structure of the virtual disk shown in FIG. 15, a directory with the name “BDMV” is prepared under “root”, and the name “Info.bdmv” is set in the directory. A file and a file with the name “MovieObjects.bdmv” are stored.

  The Info file includes information related to a menu for reproducing content recorded on the optical disk 11 and the local storage 24 and handled as being recorded on the virtual disk from the application program. The recording / playback apparatus 1 includes, for example, a playback menu including items such as playing back all content handled as recorded on a virtual disk, playing back only a specific chapter, playing back repeatedly, and displaying an initial menu. The screen is displayed on the display device based on the Info file. A MovieObject to be executed when each item is selected can be set in the Info file. When one item is selected from the playback menu screen by the user, the recording / playback apparatus 1 uses the MovieObject set in the Info file. Execute the command.

  The MovieObject file is a file including MovieObject. MovieObject includes a command for controlling playback of a PlayList that is handled as being recorded on a virtual disk, that is, a command issued by a navigation program. For example, the recording / playback apparatus 1 is assumed to be recorded on a virtual disk. By selecting and executing one of the MovieObjects to be handled, it is possible to reproduce the content that is handled as being recorded on the virtual disk. Furthermore, MovieObject includes various commands necessary for executing processing in conjunction with an application program.

  The BDMV directory also includes a directory with the name “BACKUP” (BACKUP directory), a directory with the name “PLAYLIST” (PLAYLIST directory), and a directory with the name “CLIPINF” (CLIPINF directory). , A directory (STREAM directory) in which the name “STREAM” is set, and a directory (AUXDATA directory) in which the name “AUXDATA” is set.

  In the BACKUP directory, files and data for backing up files and data handled as being recorded on the virtual disk are recorded.

  A PlayList file is stored in the PLAYLIST directory. As in the case of the optical disc 11, each PlayList file is given a name obtained by adding an extension “.mpls” to a file name consisting of five digits.

  A Clip Information file is stored in the CLIPINF directory. As in the case of the optical disc 11, each Clip Information file is given a name obtained by adding an extension “.clpi” to a file name consisting of five digits.

  In the STREAM directory, a Clip AV stream file and a substream file are stored. As in the case of the optical disc 11, each stream file is given a name obtained by adding an extension “.m2ts” to a file name consisting of a 5-digit number.

  The AUXDATA directory is not included in the Clip AV stream file or substream file handled as being recorded on the virtual disk, but is referenced from the clip AV stream file or substream file, or the clip AV stream file or substream file. A file such as data used independently of the stream file is stored.

  In the META (METADATA) directory, for example, content metadata including a title, a genre name, an actor name, a director name, a keyword, a story outline description, and connection information such as a URL of the server 3 are stored.

  Navigation programs are stored in the BDJO directory and the JAR directory.

  In the menu screen provided to the user, the information indicating the file is usually a name specified in the display_name field. For example, the directory / file structure in the virtual disk described with reference to FIG. Since it is not hidden from the navigation program or other applications or the user, the directory / file structure in the virtual disk may be presented to the user depending on the application executed in the recording / reproducing apparatus 1.

  Next, the definition of a file format for content distribution when the content author distributes content will be described with reference to FIG. The file format for distributing content may be individual distribution in units of content files, but as shown in FIG. 16, it may be an archive format including Manifest () which is a kind of metadata. .

  However, for the Package_header () section and the Package_Body () section in the archive, it is possible to obtain a text representation in a tagged language represented by XML.

  When content authors distribute content individually in units of files, Manifest (), which is a type of metadata, is handled as a single binary file or text file. In other words, Manifest () associated with the content distributed in units of files must describe an appropriate state in anticipation of the directory structure after addition.

  compression_type is a field for designating the compression method of the data in Package_Body (). If 0 is specified in this field, the data in Package_Body () is in an uncompressed format.

  Encryption_type is a field for designating a scramble method (encryption method) of data in Package_Body (). When 0 is specified in this field, the data in Package_Body () is assumed to be in a non-scramble (plain text) format.

  Note that the order of the scramble and compression of the data in Package_Body () is performed in the order of 1. compression process and 2. scramble process.

  file_count is a field for designating the total number of files to be archived.

  manifest_id is a field for designating an identifier of this Manifest () section.

  After the archive data is downloaded, the Manifest () section is stored in the local storage 24 in a corresponding download file unit (archive data unit) or merged into a single file. () The identifier of the section, manifest_id, may be used as a key.

  organization_id (org_id) is a field for designating an identifier used to construct a virtual file system on the corresponding optical disc.

  disc_id is a field for designating each optical disc 11 associated with the same org_id or an identifier for identifying content. That is, this archive is update data for the contents of the optical disc 11 specified by disc_id.

  The permission is a field for the content author to specify permission / authorization information such as whether to make the attribute visible to the user, whether to make the attribute invisible, or whether to allow overwriting of the file. Values that can be specified in Permission are the same as those described with reference to FIG. Note that the permission information may be described in any file other than the Manifest file, or may be configured as an independent file.

  src_file_name is a field for designating a path name of a file to be recorded in the local storage 24 as described with reference to FIG. It is assumed that the file / directory name is encoded in accordance with the ISO / IEC 646 standard.

  As described with reference to FIG. 14, dst_file_name is a field for designating the path name of the binding destination file in the virtual disk (virtual file system). It is assumed that the file / directory name is encoded in accordance with the ISO / IEC 646 standard.

  Note that the same name can be specified for src_file_name and dst_file_name.

  The credential describes information for checking the file access authority when the file specified in src_file_name is under a directory with a different org_id. As a result, in the local storage 24, it becomes possible to share content files among a plurality of directories under org_id.

  file_size is a field for designating the file size before compression in bytes.

  file_data is a field for designating file data as a byte sequence.

  The content distribution file format data described with reference to FIG. 16 is downloaded and merged with the data recorded on the mounted optical disk 11 in the recording / reproducing apparatus 1 to construct a virtual file system in the virtual disk. The Thereby, for example, audio or display subtitles in different languages are added to the main content recorded on the optical disc 11 from the user who reproduces the content recorded on the optical disc 11 using the recording / reproducing apparatus 1. It feels as if bonus tracks and sub-contents such as trailers were added or replaced.

  When content configured according to the above-described file format is updated, for example, in the virtual file system described with reference to FIG. 15, an information file (Info.bdmv), a movie object file (Movieobjects.bdmv), a playlist File (*****. Mpls), clip information file (*****. Clpi), stream file or AUX data file (*****. M2ts, ***** bdmv, **** New data files are downloaded and bound so that * .otf) etc. are added or updated. In order for these files to be downloaded and played back in association with the content recorded on the loaded optical disk 11, MainPath addition, SubPath addition, and the like are executed.

  When adding and updating files, if the file name stored in the local storage 24 and the newly acquired file name are the same, the file can be overwritten with the attribute described in permission. If overwriting is performed, overwriting copying is executed. If overwriting of the file is not permitted in the attribute described in permission, the overwriting copying process is not executed. In this case, even if the file copy process is not executed, the file name may be changed and the file copy process may be executed. If the file name of the newly acquired file is not the same as that of any of the files stored in advance in the local storage 24, the file is newly added to the local storage 24 and stored.

  It should be noted that AV stream data other than the above-described file structure can be recorded on the optical disc 11 and can be decoded and reproduced by the transcoder 26 or can be recorded on a different optical disc 11 or the like by executing format conversion. However, a virtual file system cannot be constructed using files downloaded to the local storage 24 in AV stream data other than the file configuration described above. Therefore, when AV stream data other than the above-described file structure is recorded on the optical disk 11, the file recorded on the optical disk 11 is added to the user who uses the recording / reproducing apparatus 1, or only a part of the file is updated. As you can see, you can't handle the data.

  In addition, the data distribution source (content author) pre-packages the files necessary for addition / update so that the recording / playback apparatus 1 does not have to execute the editing of the PlayList file. , File download may be performed for each data in the directory indicated by Disc_id).

  In this manner, in the recording / reproducing apparatus 1, new data having a configuration as shown in FIG. 16, for example, is downloaded from the server 3 via the network 2, and Manifest (a kind of metadata) ) Is stored in the local storage 24 based on the path name indicated in src_file_name described in), and the path in the virtual file system is set based on the path name indicated in dst_file_name described in Manifest (). The An application of the recording / playback apparatus 1 (for example, a navigation program for performing playback processing) is based on the virtual file system, that is, based on the path indicated by dst_file_name, the data recorded on the optical disc 11 and the local storage 24. The recorded data can be processed without distinction.

  That is, in the recording / reproducing apparatus 1, for example, upon receiving an instruction to add data (download instruction), the corresponding Manifest file (which may be all Manifest files or some Manifest files) A list of contents that can be currently added can be acquired from the server 3 by transmitting to the server 3 via the network 2. The application program can present a list of contents that can be added to the user, and can cause the user to select contents to be downloaded from the presented list.

  In addition, in the recording / reproducing apparatus 1, for example, when an instruction to add data (download instruction) is received, information necessary for specifying the data to be added is transmitted to the server 3 together with the Manifest file. In order to specify the data to be added together with the Manifest file without receiving an instruction to add data (download instruction) when the optical disk 11 is loaded, or when new data can be downloaded. By transmitting necessary information to the server 3, new data can be automatically downloaded.

  When content to be downloaded is selected by the user, or when downloading of predetermined data is automatically executed, an application (for example, data addition processing or The download of data is started by the same navigation program that can execute the reproduction process or an application program that is different from the navigation program.

  When the download is completed, the downloaded file package group is mounted on the virtual file system by the navigation program that manages the file system, and the native file system and the virtual file system are synchronized by static binding or dynamic binding. The

  Next, the reproduction process and the file system configuration process 1 will be described with reference to the flowchart of FIG.

  In step S1, the controller 21 determines whether or not the optical disk 11 is loaded. If it is determined in step S1 that the optical disk 11 is not loaded, the process of step S1 is repeated until it is determined that the optical disk 11 is loaded.

  If it is determined in step S1 that the optical disc 11 is loaded, the controller 21 executes a navigation program in step S2.

  In step S3, the optical disc directory management unit 65 of the navigation program reads org_id and disc_id from the optical disc 11, and uses the read org_id and disc_id as local storage directory management unit 64, file system merge processing unit 66, and application program linkage processing control. To the unit 71.

  In step S4, the interlocking process 1 described later with reference to FIG. 18 is executed.

  In step S5, the reproduction control unit 67 of the navigation program determines whether or not an operation input for instructing content reproduction has been received from the user, based on the operation input of the user supplied from the operation input acquisition unit 61. If it is determined in step S5 that an operation input for instructing content reproduction has not been received, the process proceeds to step S10 described later.

  If it is determined in step S5 that an operation input for instructing content reproduction has been received, the operation input acquisition unit 61 supplies a signal corresponding to the user operation input to the optical disc directory management unit 65, and the optical disc directory management unit. 65 outputs the org_id and disc_id read from the optical disc 11 to the local storage directory management unit 64, so that the binding process described later with reference to FIG. 20 is executed in step S6.

  In step S7, the playback control unit 67 controls the local storage directory management unit 64 and the optical disc directory management unit 65 to acquire the PlayList and SubPlayItem specified by the navigation program as playback sections, and the acquired PlayList and SubPlayItem refer to the PlayList and SubPlayItem. A stream file (AV file, audio file, text subtitle file, etc.) is read and supplied to the transcoder 26. Here, a time stamp represented by PlayList or SubPlayItem is converted into an address by Clip information, and an AV stream or the like is accessed.

  In step S8, the playback control unit 67 controls the transcoder 26 to play back the content specified by PlayItem.

  In step S <b> 9, the operation input acquisition unit 61 determines whether an operation input for instructing switching of a playback title (content to be played back) has been received. If it is determined in step S9 that an operation input for instructing to change the playback title has not been received, the process proceeds to step S10 described later.

  If it is determined in step S9 that an operation input for instructing to change the playback title has been received, the operation input acquisition unit 61 supplies a signal corresponding to the user's operation input to the optical disc directory management unit 65 to manage the optical disc directory management. Since the unit 65 outputs the org_id and disc_id read from the optical disc 11 to the local storage directory management unit 64, the processing returns to step S6, and the subsequent processing is repeated.

  If it is determined in step S5 that an operation input for instructing reproduction of content has not been received, or if it is determined in step S9 that an operation input for instructing change of a reproduction title has not been received, in step S10, The operation input acquisition unit 61 determines whether or not the end of the process of the recording / reproducing apparatus 1 (for example, the end of the navigation program or the power-off of the recording / reproducing apparatus 1) is commanded.

  In step S10, when it is determined that the end of the process of the recording / reproducing apparatus 1 is not instructed, the process returns to step S4, and the subsequent processes are repeated. In step S10, when it is determined that the end of the process of the recording / reproducing apparatus 1 is instructed, the process ends.

  By such processing, the data recorded in advance on the optical disc 11 and the data downloaded from the server 3 and stored in the local storage 24 are bound at a predetermined timing to construct a virtual file system. Content is played back based on the file system.

  In step S3, org_id and disc_id are read from the optical disc 11 and supplied to the application program linkage processing control unit 71. Therefore, in step S4, the controller 21 links the application program with the corresponding navigation program. Process 1 can be executed.

  Further, here, it has been described that the interlocking process 1 described later with reference to FIG. 18 is executed prior to the binding process and the content reproduction process, but the interlocking process 1 is performed at any timing during the execution of the navigation program. Needless to say, it may be executed. That is, the interlocking process 1 described later with reference to FIG. 18 can be executed at a timing desired by the creator or provider of the navigation program based on the description of the navigation program.

  Further, the controller 21 develops the application program stored in the local storage 24 and the navigation program recorded on the optical disc 11 in the memory 23 and operates them in conjunction with each other, whereby the recording / reproducing apparatus 1 is operated. Can be controlled.

  In the navigation program, a file managed by a certain Manifest file is basically a file in a virtual file system defined by org_id and disc_id. Therefore, in order for the application program and the navigation program to execute processing in conjunction with each other, the manifest file credential must be set so that the application program can access the file managed by the predetermined manifest file as necessary. Must be set.

  Specifically, for example, when playing back the optical disk 11 sold or provided by company A, the latest optical trailer can be downloaded by accessing a server managed by company A. When the navigation program executed in the virtual file system specified by the org_id and disc_id corresponding to the and the application program execute processing, the corresponding credential of each manifest file accesses this application program. Must be set to allow.

  Next, with reference to the flowchart in FIG. 18, the linkage process 1 between the navigation program and the application program executed in step S4 in FIG. 17 will be described.

  In step S41, the application program linkage processing control unit 71 determines whether or not to execute processing linked to an application program corresponding to itself (that is, the navigation program). If it is determined in step S41 that the process linked with the corresponding application program is not to be executed, the process returns to step S4 in FIG. 17 and proceeds to step S5.

  If it is determined in step S41 that the process linked with the corresponding application program is executed, in step S42, the application program linked process control unit 71 allows the recording / reproducing apparatus 1 to execute the application program. It is determined whether or not.

  Specifically, for example, when the detected application program performs processing for controlling trailer download by, for example, picture-in-picture display, the recording / playback apparatus 1 has a function of performing picture-in-picture display. If not, the recording / reproducing apparatus 1 cannot execute the detected application program. In addition, when the detected application program performs, for example, a process of controlling the downloading of a trailer including a director or a performer's comment by sub audio, the recording / reproducing apparatus 1 has a function of reproducing the sub audio. Otherwise, the recording / reproducing apparatus 1 cannot execute the detected application program.

  If it is determined in step S42 that the detected application program cannot be executed, the process returns to step S4 in FIG. 17 and proceeds to step S5.

  If it is determined in step S42 that the detected application program can be executed, application program call processing, which will be described later with reference to FIG. 19, is executed in step S43.

  In step S44, the application program linkage processing control unit 71 determines whether or not the detected application program has been successfully called in the application program call processing in step S43. If it is determined in step S44 that the detected application program has not been successfully called, the process returns to step S4 in FIG. 17 and proceeds to step S5.

  If it is determined in step S44 that the detected application program has been successfully called, in step S45, the application program linkage processing control unit 71 links the application program corresponding to itself (that is, the navigation program). The execution is controlled, and the process returns to step S4 in FIG. 17 and proceeds to step S5.

  By such processing, an application program corresponding to the navigation program is detected, it is determined whether the processing can be executed, the processing can be executed, and the calling processing is executed correctly. In this case, the navigation program and the corresponding application program are executed in conjunction with each other.

  Next, the application program call process executed in step S43 in FIG. 18 will be described with reference to the flowchart in FIG.

  In step S71, the IXC control unit 72 generates a JAVA (registered trademark) .rmi.Remote object.

  When inter-Xlet communication is executed, that is, when IXC is used, an object that implements the JAVA (registered trademark) .rmi.Remote interface is registered, searched, and used by using the IxcRegistry class. Has been made.

  In step S72, the IXC control unit 72 searches for an application to be called using ixcRegistry and notifies the search result to the application program linkage processing control unit 71.

  In step S73, the application program linkage processing control unit 71 determines whether an application program to be called is found.

  If it is determined in step S73 that the application to be called is found, the application program linkage processing control unit 71 calls the corresponding application program in step S74. That is, either the storage area of the local storage 24 that is different from the first storage area in which the file system to be bound by the navigation program is stored, or the storage area of the memory 23, and the JVM Based on the org_id and disc_id supplied in step S3 of FIG. 17 from the second storage area for storing other application programs operable above, the application program corresponding to itself (ie, the navigation program) Is detected, and the detected application program is loaded into the memory 23 and activated. After the process of step S74 is completed, the process returns to step S43 in FIG. 18 and proceeds to step S44.

  If it is determined in step S73 that the application to be called is not found, the application program linkage processing control unit 71 executes exception processing in step S75, that is, the application program is not successfully called in step S44 of FIG. As a determination, the process returns to step S43 in FIG. 18 and proceeds to step S44.

  By such processing, a corresponding application program that can perform processing in conjunction with the navigation program is called.

  Next, the binding process executed in step S6 of FIG. 17 will be described with reference to the flowchart of FIG.

  In step S <b> 101, the local storage directory management unit 64 extracts a corresponding disc_id directory from the downloaded data group recorded in the local storage 24, and supplies the directory to the file system merge processing unit 66.

  In step S102, the file system merge processing unit 66 refers to src_file_name and dst_file_name of the Manifest file.

  In step S103, the file system merge processing unit 66 binds the native file system and the virtual file system based on the src_file_name and dst_file_name referenced in step S22, and the process returns to step S6 in FIG. Proceed to step S7.

  Specifically, in src_file_name, information that can uniquely specify where this file is recorded in the directory structure in the file system of the local storage 24, that is, a “path name” representing a so-called path is specified, and dst_file_name is specified in dst_file_name. Actually, in the binding destination of the file stored in the local storage 24 in the virtual disk, information that can uniquely specify where this file is recorded in the directory structure, that is, a “path name” representing a so-called path is specified. .

  For example, in the Manifest () section described with reference to FIG. 16, the path name “/MainMovie/movie01/main.r1.jp.mp2” is specified in the src_file_name field, and “/ STREAM / 01002. When the path name is specified as “m2ts”, the file system merge processing unit 66, as described with reference to FIG. 14, download data is stored in the local storage 24 under the corresponding org_id and disc_id. It is recorded in the movie01 folder in the MainMovie folder with the file name main.r1.jp.mp2, but in the virtual file system on the virtual disk, it is bound so that it is handled as a file with the file name 01002.m2ts in the STREAM directory To do.

  The content author can specify the path name in the local storage 24 in the src_file_name field of the Manifest () section of the file package to be downloaded, and can specify the path name in the virtual file system in the virtual disk in the dst_file_name field. . Therefore, if the path name adapted to the virtual file system in the virtual disk (adapted to the file system of the optical disk 11) is set in the field of dst_file_name, the content author actually records in the local storage 24 of the recording / playback apparatus 1. It is possible to freely set the file / directory structure below the disc_id of the data to be added and newly add a directory or file to the area below the disc_id.

  By the way, the processing executed in conjunction with the navigation program and the application program executed in step S45 in FIG. 18 includes so-called trailers such as trailers and advertisements of other contents, and bonuses such as director commentary, for example. Update content such as subtitles for main content such as tracks or subtitles in a language other than the currently displayable language in the main content, corresponding to the content supplier (content author, content provider, distributor, etc.) There is a process of downloading from a predetermined server or the like. Specifically, for example, the recording / reproducing apparatus 1 is recorded on the mounted optical disk 11 in the server 3 that can exchange information with the recording / reproducing apparatus 1 via the network 2 described with reference to FIG. The sub-contents can be downloaded from a predetermined server related to the content in question or designated by the content supplier (content author, content provider, distributor, etc.) .

  Here, as a process executed in conjunction with the navigation program and the application program, the content recorded on the mounted optical disc 11 or the content supplier (content author, content provider, distributor, etc.) Automatically download the latest trailer that matches the user's preference as the corresponding sub-content, or that the content supplier (content author, content provider, distributor, etc.) wants to present to the user A case where an application capable of performing the above is executed will be described.

  That is, when the optical disc 11 is mounted on the recording / reproducing apparatus 1, the navigation program is executed, the application program of a predetermined resident is started by the navigation program, and these are executed in conjunction with each other to execute the processing. Information regarding the content recorded on the optical disc 11 is transmitted to a predetermined server, and the trailer is automatically downloaded. The downloaded trailer may be the latest trailer of the corresponding content author, or may be a trailer that seems to match the user's preference.

  When downloading a trailer that seems to match the user's preference, for example, the user views the content based on information about the content of the optical disc 11 mounted on the recording / reproducing apparatus 1, in other words, a user who likes the content. It is preferred that the latest trailer for other content that is likely to be selected is selected and downloaded. Moreover, the preference information of the user who uses the recording / reproducing apparatus 1 may be input and accumulated by the user. Then, the downloaded trailer stream data is bound by the processing of the navigation program so that it can be reproduced together with the main content.

  Also, information related to the contents of the optical disc 11 mounted on the recording / reproducing apparatus 1 and user preference information are transmitted from the recording / reproducing apparatus 1 to the server, and information relating to the user's preference is accumulated in the server. Trailers that match your preferences may be downloaded.

  That is, when the optical disc 11 is mounted on the recording / reproducing apparatus 1, the navigation program is executed, the application program of a predetermined resident is started by the navigation program, and these are executed in conjunction with each other to execute the processing. Information relating to the content recorded on the optical disc 11 and user preference information are transmitted to a predetermined server. In the server, for each user, information on the content recorded on the optical disc 11 reproduced by the recording / reproducing apparatus 1 and preference information input by the user are accumulated for each user, and based on the accumulated information. The latest trailer that matches the user's preference is retrieved and transmitted to the recording / reproducing apparatus 1 together with the PlayList and Manifest file necessary for reproducing the trailer. The downloaded trailer video is bound by the processing of the navigation program so that it can be reproduced together with the content.

  Further, in the recording / reproducing apparatus 1, the user's preference information using the recording / reproducing apparatus 1 is accumulated, and the user's preference information is transmitted from the recording / reproducing apparatus 1 to the server. Trailers that match the user's preference may be downloaded.

  That is, in the recording / reproducing apparatus 1, a user's preference is extracted by executing a predetermined resident application program. For example, when the user's preference information is acquired from information about content that is played back and viewed from the optical disc 11, information about the content is obtained by executing a predetermined resident application program and a navigation program in conjunction with each other. Are supplied to the application program and classified and stored for each user.

  Then, when the optical disc 11 is mounted on the recording / reproducing apparatus 1, a navigation program is executed, and an application program having a predetermined resident is started by the navigation program. Information about the user's preference is transmitted to a predetermined server, and the latest trailer that matches the user's preference is automatically downloaded. For example, if the user of the recording / playback apparatus 1 tends to like an action movie, the latest trailer of the action movie is mainly downloaded from the server related to the content author of the mounted optical disk 11. Then, the downloaded trailer video is bound by the processing of the navigation program so that it can be reproduced together with the main content.

  The trailer may be played back at any timing with respect to content playback, for example. For example, if the main content is a movie, the trailer may be played at the beginning of the main movie, or it may be played at any time, or may be selectively played only when a command is received from the user.

  When the trailer is configured to be selectively reproducible, for example, the trailer download may be executed only when a new trailer replay that matches the user's preference is instructed. . Specific processing when the trailer is downloaded based on a new trailer reproduction instruction by the user will be described later with reference to FIGS.

The connection destination information acquisition unit 162 acquires connection information such as the URL of the server 3 that is the download destination of the trailer from the navigation program 151 using IXC, and supplies the connection information to the content information transmission unit 163.

  In step S142, the content information transmission unit 163 of the application program 152 connects the information such as the metadata of the content recorded on the mounted optical disc 11 obtained by the content information acquisition unit 161 described above. The information is transmitted to a predetermined server 3 corresponding to the connection destination obtained by the destination information acquisition unit 162.

  Then, in the server 3, processing described later with reference to FIG. 24 is executed.

  In step S143, the data transfer control unit 63 of the navigation program 151 downloads the trailer data from the server 3, and the local storage directory management unit 64 records the downloaded trailer data in a predetermined recording area of the local storage 24. To do.

  In step S144, the binding process described with reference to FIG. 20 is executed, and the process ends.

  In the first example, the content recorded on the optical disc 11 in which the recording / reproducing apparatus 1 is mounted, the latest trailer related to the author of the optical disc 11, or the content can be viewed by such processing. It is possible to download a trailer or the like of content that the user is likely to like.

  In this way, the downloaded trailer data is bound in step S6 and reproduced in step S8 when a reproduction command is received from the user in step S5 in FIG.

  Next, referring to the flowchart of FIG. 24, the supply of information relating to the content recorded on the optical disc 11 mounted on the recording / reproducing apparatus 1 is selected, and an optimum trailer is selected, and the recording / reproducing apparatus 1 is selected. The server process 1 executed by the server 3 that can be supplied will be described.

  In step S171, the content information receiving unit 171 of the server 3 transmits information from the recording / reproducing apparatus 1 regarding the optical disc 11 or content necessary for trailer acquisition (for example, content metadata and transmission of this metadata). Information indicating the origin) is received and supplied to the trailer selection unit 172. The trailer selection unit 172 acquires information regarding the optical disc 11 or content from the content information reception unit 171.

  In step S172, the trailer selection unit 172 selects and reads trailer data to be transmitted to the recording / reproducing apparatus 1 from the trailer database 104. Specifically, for example, the trailer selection unit 172 searches for the latest trailer designated by the content author of the optical disk 11 mounted on the recording / reproducing apparatus 1 or searches the optical disk 11 mounted on the recording / reproducing apparatus 1. Based on data such as genres and actors included in the recorded content metadata, a trailer of content that the user viewing the optical disc 11 is likely to like is retrieved and supplied to the trailer transmission unit 173.

  In step S173, the trailer transmission unit 173 transmits the read trailer data to the recording / reproducing apparatus 1, and the process is terminated.

  By such processing, the server 3 views the optical disc 11 mounted on the recording / reproducing apparatus 1 or the latest trailer related to the content recorded on the optical disc 11 and the content recorded on the optical disc 11. It is possible to cause the corresponding recording / playback apparatus 1 to download a trailer or the like of content that the user is likely to like.

  Next, as a second example of processing, information related to the contents of the optical disc 11 mounted on the recording / reproducing apparatus 1 is transmitted from the recording / reproducing apparatus 1 to the server 3. Will be described, and a trailer that matches the user's preference will be downloaded to the recording / reproducing apparatus 1.

  FIG. 25 is a functional block diagram illustrating functions of the controller 21 of the recording / reproducing apparatus 1 and the CPU 101 of the server 3 in order to implement the second example.

  That is, in the recording / reproducing apparatus 1, in place of the application program 152, in addition to the content information acquisition unit 161 and the connection destination information acquisition unit 162, the user information acquisition unit 211 and the content information are the same as in the first example. An application program 201 having the function of the transmission unit 212 is executed.

  The user information acquisition unit 211 acquires preference information, such as a genre, an actor, a director, and a keyword, which the user likes, input from the user by the operation input unit 29 and holds the preference information for each user. When transmitting information for acquiring a trailer to the server 3, the user information acquisition unit 211 prompts the user to input, for example, a user name or a user ID of a user who is currently using the recording / playback apparatus 1. Thus, the user who views the trailer to be downloaded this time is specified, and the preference information of the user is supplied to the content information transmission unit 212 together with the user name, the user ID, and the like.

  The content information transmission unit 212 receives information such as user preference information and user names and user IDs supplied from the user information acquisition unit 211 and metadata supplied from the content information acquisition unit 161 as connection destination information. Based on the connection information supplied from the acquisition unit 162, the information is transmitted to the server 3 via the network 2. In the second example, since the server 3 stores user preference information, information to be transmitted to the server 3 is determined based on items of user preference information stored by the server 3. That is, in the second example, in addition to the content metadata, such as the user preference information and the user name or user ID that identifies the user, and information indicating the transmission source of this metadata, as necessary IDs such as disc_id and org_id may be transmitted.

  Then, the preference information input by the user, the information related to the mounted optical disc 11 or the information related to the content recorded on the optical disc 11 is supplied from the recording / reproducing apparatus 1 and the preference information is accumulated for each user. In addition, the CPU 101 of the server 3 that can select the optimal trailer based on the accumulated user preference information and supply the trailer to the recording / reproducing apparatus 1 adds to the trailer transmission unit 173 in the first example. Thus, the content information receiving unit 221, the preference information registration processing unit 222, and the trailer selection unit 223 have functions, and a preference information database 231 is constructed in the storage unit 109.

  The content information reception unit 221 transmits information necessary for trailer acquisition transmitted from the recording / reproducing apparatus 1 (for example, user preference information and a user name or user ID for identifying the user, and the recording / reproducing apparatus 1). Content metadata recorded on the mounted optical disk 11 (ie, viewed by this user), the transmission source of this metadata, in other words, information indicating the trailer request source, and if necessary, disc ID, org_id, etc.) and supply it to the preference information registration processing unit 222, and also supplies the trailer selection unit 223 with a user name or user ID for identifying the user and information indicating the requester of the trailer. , Request execution of trailer selection processing.

The information which becomes the user preference information is received and registered for each user.

  In the preference information database 231, not only the preference information entered by the user by the user information acquisition unit 211 but also information related to the content viewed by the user can be registered. For example, the time after the user inputs the preference information Even when the preference gradually changes over time, it becomes possible to follow the user's preference. Also, preference information entered by the user himself / herself, even for users who view various contents regardless of their preferences, that is, users who have difficulty understanding the user's preferences only by information about the contents viewed by the user. Based on the above, it is possible to provide the user with a trailer that matches the user's preference.

  The trailer selection unit 223 receives a request for execution of trailer selection processing, refers to the preference information database 231 provided in the storage unit 109, and trailers the content that the user specified by the user name or user ID is likely to like. Is retrieved from the trailer database 104 and supplied to the trailer transmission unit 173. The trailer transmission unit 173 transmits the trailer data selected by the trailer selection unit 223 to the recording / reproducing apparatus 1.

  When selecting a trailer, the trailer selection unit 223 may weight each item registered in the preference information database 231. For example, the trailer selection unit 223 may weight each preference information input by the user himself / herself, may weight items related to the content the user is viewing, Weights the preference information entered by the user and the "actor" item of the content viewed by the user, or weights the preference information entered by the user and the "genre" of the content viewed by the user You may do it.

  Moreover, when selecting the trailer, the trailer selection unit 223 may use only one of the items registered in the preference information database 231. For example, the trailer selection unit 223 may use only the preference information input by the user himself / herself for the selection of the trailer, or may use only the items related to the content that the user is viewing for the selection of the trailer. Then, only the preference information input by the user and the “actor” item and the “genre” item of the content viewed by the user may be used for selecting the trailer.

  When only specific items are used for trailer selection, information on items that are not used for trailer selection may not be transmitted from the recording / reproducing apparatus 1 or may be transmitted from the recording / reproducing apparatus 1. However, it goes without saying that it may not be registered in the preference information database 231.

  Next, referring to the flowchart of FIG. 26, the user preference information is transmitted from the recording / playback apparatus 1 to a predetermined server 3, the user preference information is accumulated in the server 3, and the latest information that matches the user preference.

  The user information acquisition unit 271 of the application program 261 acquires preference information, such as a genre, an actor, a director, and a keyword, which is input by the user through the operation input unit 29 and holds the information for each user. In step S262, the user information acquisition unit 271 specifies a user who views the trailer to be downloaded this time, for example, by prompting the user to input a user name, a user ID, or the like of the user who is currently using the recording / playback apparatus 1. Then, the user's preference information is supplied to the preference information acquisition unit 272 together with the user name and user ID. The preference information acquisition unit 272 includes, in addition to the metadata of the content supplied from the content information acquisition unit 161, information for specifying a user such as a user name and a user ID, and preference information for the user, and preference information accumulation control To the unit 273.

  In step S263, the preference information accumulation control unit 273 receives the preference information input from the user supplied from the preference information acquisition unit 272 and the metadata of the content recorded on the optical disc 11 for each user. Register in a predetermined area of the local storage 24.

  In step S264, the preference information transmission unit 274 uses the preference information accumulation control unit 273 to perform local processing based on the user name, user ID, and the like of the user who is currently using the recording / playback device 1 supplied from the user information acquisition unit 271. The corresponding user preference information accumulated in the storage 24 is read out and transmitted to the predetermined server 3 corresponding to the connection destination obtained by the connection destination information acquisition unit 162 via the network 2.

  Then, in the server 3, processing described later with reference to FIG. 30 is executed.

  In step S265, the data transfer control unit 63 of the navigation program 151 downloads the trailer data from the server 3, and the local storage directory management unit 64 records the downloaded trailer data in a predetermined recording area of the local storage 24. To do.

  In step S266, the binding process described with reference to FIG. 20 is executed, and the process ends.

  In the third example, the user's preference information is accumulated in the recording / reproducing apparatus 1 by such processing, and the preference information of the user who uses the recording / reproducing apparatus 1 is transmitted to the server 3, and the user's preference information is transmitted. It is possible to download the latest trailer that matches your preferences.

  In this way, the downloaded trailer data is bound in step S6 and reproduced in step S8 when a reproduction command is received from the user in step S5 in FIG.

  Next, referring to the flowchart of FIG. 30, the server 3 that can receive the user's preference information from the recording / reproducing apparatus 1, select the optimum trailer, and supply the selected trailer to the recording / reproducing apparatus 1 is executed. Processing 3 of the server to be performed will be described.

  In step S <b> 291, the preference information receiving unit 281 of the server 3 receives the user preference information transmitted from the recording / reproducing apparatus 1 and supplies it to the trailer selecting unit 223.

  In step S292, the trailer selection unit 223 selects and reads the trailer of content that matches the user's preference from the trailer database 104 based on the user's preference information supplied from the preference information reception unit 281 and the trailer transmission unit 173. To supply.

  In step S293, the trailer transmission unit 173 transmits the read trailer data to the recording / reproducing apparatus 1, and the process is terminated.

  By such processing, the server 3 can cause the corresponding recording / reproducing apparatus 1 to download the latest trailer that matches the user's preference based on the user's preference information.

  In the above description, the resident application program is activated by the navigation program and the process is executed in conjunction with the resident application program. However, the resident application program can be activated even when the navigation program is not activated. A part of the processing may be executed independently of the navigation program.

  Further, in the processing described above, the resident application program has been described as transmitting information related to user preferences to the server 3, but the resident application has only a function of registering user preference information. The navigation program may further have a function of transmitting information related to user preferences to the server 3.

  For example, when the user's preference information can be acquired also by the user's operation input, the user's preference information is acquired and registered even when the navigation program is not activated. It is possible.

  Therefore, the resident application program may be able to execute the user preference information acquisition and registration processing even when the navigation program is not activated. When the optical disc 11 is loaded and the navigation program is activated, the navigation program acquires user preference information registered by the application program, transmits it to the server 3, and executes a process of downloading the corresponding trailer. To do.

  Next, as a fourth example of processing, in the recording / reproducing apparatus 1, the user's preference information using the recording / reproducing apparatus 1 is accumulated using a resident application, and recorded by the navigation program processing. A case will be described in which information related to user preferences is transmitted from the playback apparatus 1 to the server 3 and a trailer that matches the user preferences is downloaded.

  FIG. 31 is a functional block diagram showing functions of the controller 21 of the recording / reproducing apparatus 1 when the navigation program for realizing the fourth example is executed.

  In addition, the same code | symbol is attached | subjected to the part corresponding to the case mentioned above using FIG. 6, The description is abbreviate | omitted suitably.

  That is, the navigation program for realizing the fourth example further includes the function of the preference information acquisition unit 301 in addition to the functions described with reference to FIG.

  The preference information acquisition unit 301 acquires user preference information accumulated by an application program having a function of accumulating user preference information from the application program using IXC, and supplies it to the data transfer control unit 63. The server 3 is supplied via the network 2.

  FIG. 32 is a functional block diagram illustrating functions of the controller 21 of the recording / reproducing apparatus 1 and the CPU 101 of the server 3 in order to implement the fourth example.

  The navigation program 311 has the functions described with reference to FIG. 31, and uses the application program 312 having the function of storing user preference information and the IXC to exchange information, and the preference information of the user who views the trailer to be downloaded. Is transmitted to the server 3, the trailer is downloaded, and the binding process and the reproduction process of the downloaded trailer are executed.

  The application program 312 has the functions of the user information acquisition unit 271, the preference information acquisition unit 272, and the preference information accumulation control unit 273 in the third example described with reference to FIG. Accumulating and supplying preference information of a predetermined user to the navigation program 311 using IXC.

  In the fourth example, the CPU 101 of the server 3 that can receive the user's preference information from the recording / reproducing apparatus 1, select the optimum trailer, and supply the selected trailer to the recording / reproducing apparatus 1, It has the same function as in the third example.

  Next, with reference to the flowchart of FIG. 33, the reproduction process and the file system configuration process 2 executed by the recording / reproducing apparatus 1 in the case of the fourth example will be described.

  In step S321, the controller 21 determines whether or not the user is instructed to execute the resident application program 312 by the operation input unit 29. If it is determined in step S321 that execution of the resident application program 312 is not instructed, the process proceeds to step S324 described later.

  If it is determined in step S321 that execution of the resident application program 312 is instructed, the controller 21 activates the application program 312 in step S322, and executes the application program 312 in step S323. The application program 312 registers user preference information input from the user.

  If it is determined in step S321 that execution of the resident application program 312 is not instructed, or after the processing in step S323 is completed, the controller 21 determines in step S324 whether or not the optical disk 11 is loaded. To do. If it is determined in step S324 that the optical disk 11 is not loaded, the process of step S324 is repeated until it is determined that the optical disk 11 is loaded.

  If it is determined in step S324 that the optical disc 11 is loaded, the controller 21 executes the navigation program 311 in step S325.

  In step S326, the application program linkage processing control unit 71 determines whether or not to execute processing linked with the application program corresponding to itself (that is, the navigation program 311). If it is determined in step S326 that the process linked with the corresponding application program is not to be executed, the process proceeds to step S328 described later.

  If it is determined in step S326 that processing associated with the corresponding application program is to be executed, in step S327, the application program interlocking processing control unit 71 executes call processing of the application program, and performs itself (ie, The navigation program 311) and the corresponding application program 312 are linked to control their execution. For example, when the metadata of the mounted optical disk 11 is used as user preference information, the navigation program 311 reads the metadata from the optical disk 11 and supplies the metadata to the application program 312 using IXC. Register as information. Then, the navigation program 311 executes processing described later with reference to FIG. 35 in conjunction with the application program 312.

  If it is determined in step S326 that the process linked to the corresponding application program is not to be executed, or after the process of step S327 is completed, steps S328 to S333 are the same as steps S5 to S10 of FIG. Processing is executed.

  That is, based on the user's operation input supplied from the operation input acquisition unit 61, it is determined whether or not the user has received an operation input for instructing content reproduction, and the operation input for instructing content reproduction has been received. When the determination is made, after the binding process described with reference to FIG. 20 is executed, the PlayList and SubPlayItem specified by the navigation program 311 as the playback section are acquired, and the stream file (AV that is referred to by the acquired PlayList and SubPlayItem) File, audio file, text subtitle file, etc.) are read, and the content specified by PlayItem is played.

  Then, it is determined whether or not an operation input for instructing switching of a reproduction title (content to be reproduced) has been received. If it is determined that an operation input for instructing a change of the reproduction title has been received, the process returns to step S329. When the subsequent processing is repeated and it is determined that the operation input for instructing the reproduction of the content has not been received, or when it is determined that the operation input for instructing the change of the reproduction title has not been received, It is determined whether or not the end of the process 1 (for example, the end of the navigation program or the power-off of the recording / reproducing apparatus 1) is instructed. If it is determined that the end of the process of the recording / reproducing apparatus 1 is not instructed, the process returns to step S321, and the subsequent processes are repeated to determine that the end of the process of the recording / reproducing apparatus 1 is instructed. If so, the process is terminated.

  By such processing, the resident application program 312 is executed when the navigation program 311 is not activated, and the resident application program 312 is executed in conjunction with the navigation program 311.

  Next, user preference information registration processing executed by the application program 312 when the navigation program 311 is not activated will be described with reference to the flowchart of FIG.

  In step S361, the user information acquisition unit 271 of the application program 312 determines whether or not the user has input preference information such as a genre, an actor, a director, and a keyword that the user likes via the operation input unit 29. to decide. If it is determined in step S361 that information regarding the user has not been input, the processing in step S361 is repeated until it is determined that input has been received.

  If it is determined in step S361 that information related to the user has been input, in step S362, the user information acquisition unit 271 sends the input information to the preference information accumulation control unit 273 via the preference information acquisition unit 272. Supply. The preference information accumulation control unit 273 registers the preference information input by the user in a predetermined area of the local storage 24 for each user, and the process is terminated.

  By such processing, even when the navigation program 311 is not activated, registration processing of user preference information is executed by processing of the application program 312.

  Next, referring to the flowchart of FIG. 35, the user preference information accumulated in the recording / reproducing apparatus 1 is transmitted to a predetermined server 3, and the latest trailer that matches the user preference information is automatically transmitted from the server 3. The trailer download process 4, which is an example of the process executed in step S327 of FIG.

  In step S391, the navigation program 311 extracts from the information recorded on the optical disc 11 information necessary for downloading the trailer, such as metadata and the URL of the trailer download destination, among which user preference information Information that needs to be registered is supplied to the application program 312.

  In step S392, the preference information acquisition unit 272 of the application program 261 supplies the content metadata supplied from the navigation program 311 to the preference information accumulation control unit 273.

  In step S393, the preference information accumulation control unit 273 uses the metadata of the content recorded on the optical disc 11 supplied from the preference information acquisition unit 272 as the user preference information, for each user, in the predetermined storage in the local storage 24. Register in the area.

In step S394, the navigation program 311 identifies the user who views the trailer to be downloaded this time, for example, by prompting the user to input the user name or user ID of the user who is currently using the recording / playback apparatus 1, By exchanging information with the application program 312 using IXC, the corresponding preference information stored in the local storage 24 is read by the preference information accumulation control unit 273 based on the user name, user ID, and the like of the user. Then, the data is transmitted to the predetermined server 3 corresponding to the connection destination obtained by the connection destination information acquisition unit 162 via the network 2.

  Then, the server 3 executes the process described with reference to FIG.

  In step S395, the data transfer control unit 63 of the navigation program 151 downloads the trailer data from the server 3, and the local storage directory management unit 64 records the downloaded trailer data in a predetermined recording area of the local storage 24. To do.

  In step S396, the binding process described with reference to FIG. 20 is executed, and the process ends.

  In the fourth example, the user preference information is accumulated by the process of the application program 312 in the recording / reproducing apparatus 1 by such processing, and the user who uses the recording / reproducing apparatus 1 by the process of the navigation program 311 is used. Is transmitted to the server 3, and the latest trailer that matches the user's preference can be downloaded.

  In this way, the downloaded trailer data is bound in step S6 and reproduced in step S8 when a reproduction command is received from the user in step S5 in FIG.

  Further, as described above, when the trailer is configured to be selectively reproducible, for example, the trailer download may be executed only when the trailer regeneration is instructed. As a fifth example of processing, in the recording / reproducing apparatus 1, the trailer can be selectively reproduced, and the user's preference information using the recording / reproducing apparatus 1 is accumulated using a resident application. Next, a case will be described in which when trailer reproduction is instructed, information on user preferences is transmitted and the trailer is downloaded.

  For example, as shown in FIG. 36, a button 322 for instructing the user to start playback of the main content (main content) of the content, a button 323 for instructing playback of the trailer (sub-content), and various setups A GUI display screen 321 including a button 323 for starting the trailer may be presented, and the trailer may be played back only when the button 323 is pressed and playback of the trailer is commanded.

  When the button 323 is pressed, as shown in FIG. 37, a button 332 for instructing reproduction of the trailer recorded on the mounted optical disk 11, a button 333 for instructing download and reproduction of the latest trailer, In addition, a GUI display screen 331 including a button 334 for instructing download and playback of the trailer that matches the user's preference may be presented to the user.

  When the button 333 or the button 334 is selected on the GUI display screen 331 of FIG. 37, as shown in FIG. 38, a bar 342 indicating that the trailer is currently being downloaded, and the trailer A GUI display screen 341 provided with a button 343 for instructing reproduction may be presented to the user.

  In any of the first example, the second example, the third example, and the fourth example described above, when the trailer regeneration is instructed so that the trailer can be selectively reproduced. Needless to say, it is possible to execute a trailer download.

  Referring to the flowchart of FIG. 39, the trailer can be selectively played back, and the playback performed by the recording / playback apparatus 1 when the trailer download is executed only when the trailer playback is instructed. Processing and file system configuration processing 3 will be described.

  In steps S421 to S425, the same processing as in steps S321 to S325 of FIG. 33 is executed.

  That is, it is determined whether or not the execution of the resident application program is instructed by the user. When it is determined that the execution of the resident application program is instructed, the application program is started and the application program is executed.

  Then, it is determined whether or not the optical disk 11 is mounted. If it is determined that the optical disk 11 is mounted, a navigation program is executed.

  In step S426, the reproduction control unit 67 of the navigation program determines whether or not an operation input for instructing reproduction of content has been received from the user based on the user's operation input supplied from the operation input acquisition unit 61. If it is determined in step S426 that an operation input commanding content reproduction has not been received, the process proceeds to step S433 described later.

  If it is determined in step S426 that an operation input for instructing playback of content has been received, in step S427, the application program linkage processing control unit 71 performs processing linked to the application program corresponding to itself (that is, the navigation program). It is determined whether or not to execute. If it is determined in step S427 that the process linked with the corresponding application program is not to be executed, the process proceeds to step S429 described later.

  If it is determined in step S427 that processing associated with the corresponding application program is to be executed, in step S428, the application program interlocking processing control unit 71 executes call processing of the application program, and performs itself (ie, The application program corresponding to the navigation program) is linked to control the execution thereof. For example, when the button 333 or the button 334 is selected on the GUI display screen 331 in FIG. 37, the method of any one of the first to fourth examples described above is applied to match the user's preference. Alternatively, a process for downloading the latest trailer is executed in conjunction with the application program.

  If it is determined in step S427 that the process linked with the corresponding application program is not to be executed, or after the process of step S428 is completed, steps S429 to S433 are the same as steps S5 to S10 of FIG. Processing is executed.

  That is, the binding process described with reference to FIG. 20 is executed, the PlayList and SubPlayItem specified by the navigation program as playback sections are acquired, and the stream files (AV file, audio file, text that are referred to by the acquired PlayList and SubPlayItem are acquired. Subtitle file etc.) is read and the content specified by PlayItem is played.

  Then, it is determined whether or not an operation input for instructing switching of a reproduction title (content to be reproduced) has been received. If it is determined that an operation input for instructing a change of the reproduction title has been received, the process returns to step S427. When the subsequent processing is repeated and it is determined that the operation input for instructing the reproduction of the content has not been received, or when it is determined that the operation input for instructing the change of the reproduction title has not been received, It is determined whether or not the end of the process 1 (for example, the end of the navigation program or the power-off of the recording / reproducing apparatus 1) is instructed. If it is determined that the end of the process of the recording / reproducing apparatus 1 has not been instructed, the process returns to step S421, and the subsequent processes are repeated to determine that the end of the process of the recording / reproducing apparatus 1 has been instructed. If so, the process is terminated.

  By such processing, in any of the first example, the second example, the third example, and the fourth example described above, the trailer can be selectively regenerated, and the trailer It is possible to download the trailer only when playback is commanded.

  Next, with reference to FIG. 40 and FIG. 41, a method of manufacturing the optical disc 11 on which data that can be reproduced by the recording / reproducing apparatus 1 is recorded will be described by taking the case where the optical disc 11 is a disc-shaped recording medium as an example.

That is, as shown in FIG. 40, a master disc made of, for example, glass is prepared, and a recording material made of, for example, a photoresist is applied thereon. As a result, a recording master is produced.

  As shown in FIG. 41, in the software production processing unit, video data in a format reproducible by the recording / reproducing apparatus 1 encoded by the encoding apparatus (video encoder) is stored in a temporary buffer, In addition to the audio data encoded in the above, the data other than the stream (for example, Indexes, PlayList, PlayItem, etc.) encoded by the data encoder is stored in the temporary buffer. Video data, audio data, and data other than the stream stored in each buffer are multiplexed together with a synchronization signal by a multiplexer (MPX), and an error correction code is added by an error correction code circuit (ECC). Is done. Then, predetermined modulation is applied by a modulation circuit (MOD), and software that is once recorded on, for example, a magnetic tape in accordance with a predetermined format and recorded on the optical disk 11 that can be reproduced by the recording / reproducing apparatus 1 is manufactured.

  This software is edited (premastered) as necessary, and a signal of a format to be recorded on the optical disk 11 is generated. In response to this recording signal, the laser beam is modulated, and this laser beam is irradiated onto the photoresist on the master. Thereby, the photoresist on the master is exposed in accordance with the recording signal.

  Then, this master is developed and pits appear on the master. The master plate thus prepared is subjected to a process such as electroforming to produce a metal master plate in which pits on the glass master plate are transferred. A metal stamper is further produced from this metal master, and this is used as a molding die.

  A material such as PMMA (acrylic) or PC (polycarbonate) is injected into this molding die by, for example, injection and fixed. Alternatively, 2P (ultraviolet curable resin) or the like is applied on the metal stamper and then cured by irradiation with ultraviolet rays. Thereby, the pits on the metal stamper can be transferred onto the replica made of resin.

  A reflective film is formed on the replica thus generated by vapor deposition or sputtering. Alternatively, a reflective film is formed on the generated replica by spin coating.

  Thereafter, the inner and outer diameters of the disk are processed, and necessary measures such as bonding two disks are performed. Further, a label is attached or a hub is attached and inserted into the cartridge. In this way, the optical disc 11 on which data reproducible by the recording / reproducing apparatus 1 is recorded is completed.
