Fig. 2 A illustrates to 2D and is recorded in recording medium (for example, the various examples of the file structure on BD-ROM).
To the file structure of Fig. 2 A be elaborated now.In reproducing management file structure, comprise at least one BD catalogue (BD directory) in the root directory.Each BD catalogue comprises that index file (" index.bdmv " and " index.bdj ") and obj ect file (" MovieObject.bdmv " and " JavaObjcet.bdj ") are as the general file information that is used to guarantee with one or more users' interactivity.Each BD catalogue comprises three file directorys, and they comprise the data that will reproduce and reproduce the required information of these data.In each BD catalogue included file directory be playlist directory (PLAYLIST), clip information directory (CLIPINF), stream catalogue (STREAM), the auxiliary data directory (AUXDATA) that contains the Java catalogue (JAVA) of one or more java applet files and comprise the auxiliary data that is associated with the reproduction of CD.Below will describe above-mentioned catalogue and the file that is included in each catalogue in detail.
The stream catalogue comprises with specific format and is recorded in a plurality of AV stream files in the CD.For example, "
*.m2ts " be used to name stream file (for example, 01000.m2ts).In addition, clip information directory (CLIPINF) comprise with stream in the catalogue included each stream file one to one clip information file (for example, 01000.clpi ...).Clip information file (
*.clpi) comprise the attribute information and the timing information of respective streams file.More specifically, in the BD standard, stream file and with this stream file one to one clip information file (
*.clpi) be collectively referred to as " montage ".In other words, corresponding to each stream file (
*Clip information file .m2ts) (
*.clpi) must exist.
Playlist directory (PLAYLIST) comprise a plurality of play list file (
*.mpls), wherein each play list file (for example, 00000.mpls) comprises that between the broadcast area of specifying specific clips at least one play.In other words, play item and comprise the information that presents starting and ending time (IN-Time and OUT-Time) of specifying specific clips.At this, concrete montage is specified by playing an interior clip_Information_File_name.Play list file (
*.mpls) reproduce required montage from one or more combinations of playing item.In addition, play list file (
*.mpls) also comprise and be used to reproduce and play by the son of playing a data that the data of reproducing are different (particularly being subdata).
More specifically, the command operation (or execution) only made of play list file according to the special object in the obj ect file (" MovieObject.bdmv " and " JavaObject.bdmv ").Thus, from the angle of dish reproduction script, this object is carried out or the management dynamic script, and play list file (
*.mpls) carry out or manage static scenario.In addition, Java catalogue (JAVA) comprise the java applet file (for example, PPPPP.jar ...).Programming has various types of application in being called each java applet file of " Xlet " especially.The java applet file is handled by Java specific reproduction device, and this will describe in detail with reference to figure 11B after a while.
Auxiliary data directory (AUXDATA) comprises the file that contains the supplementary that is associated with the reproduction of CD. for example, AUXDATA (for example can comprise audio files (" Sound.bdmv "), font file, " 11111.otf "). audio files provides such as information such as click sound and menu sound information when reproducing CD. font file provides font information when reproducing text header. according to the present invention, AUXDATA also can comprise the search file that is used to search for one group of specific in CD content ("
*.esi ").
Referring to Fig. 2 A, when disposing search file according to the present invention, can be to every kind of independent search file of language configuration.For example, but with the search file called after " 01001.esi " of configured in English, but with the search file called after " 01002.esi " of configured in Korean, but and with the search file called after " 01003.esi " of configured in Japanese.The configuration of search file will describe in detail with reference to figure 5 after a while.
Fig. 2 B illustrates another example according to file structure of the present invention.Compare referring to Fig. 2 B and with the structure of Fig. 2 A, when disposing search file according to the present invention, all language of being supported can be configured in the single search file.For example, English, Korean and Japanese can be all supported in same search file " 01001.esi ".In single search file, support the configuration of all language describing in detail with reference to figure 9A and Fig. 9 B after a while.
Fig. 2 C illustrates the another example according to file structure of the present invention.Compare referring to Fig. 2 C and with the structure of Fig. 2 A and 2B, when disposing search file according to the present invention, this search file is included in independent metadata catalog (META) rather than the auxiliary data directory (AUXDATA).At this, search file uses the specific file that is different from other meta data file.More specifically, the BD catalogue comprises metadata catalog (META).But search file according to the present invention is recorded into the filename that has such as " esmt_LLL_xxxxx.xml ".In other words, the top of filename " esmt_ " is used as the filec descriptor sign indicating number that search file and other meta data file are made a distinction.Therefore, all represent search file (and particularly, being " enhanced search meta data ") with the file of " esmt_ " beginning.On the other hand, all represent the file of making an inventory of goods in a warehouse with the file of " dlmt_ " beginning.
In addition, " _ the LLL_ " that also disposes search file is used as the language code of distinguishing and identify the language message that this search file supports.More specifically, the search file with configured in English can be indicated as " _ eng_ ".Similarly, can be indicated as " _ kor_ " with the search file of configured in Korean, and can be indicated as " _ jpn_ " with the search file of configured in Japanese.And, can be indicated as " _ mul_ " with the search file of multilingual configuration.In addition, the end of filename " _ xxxxx " be used as the play list file that is used to distinguish corresponding to the search information of included this search file of configuration (for example, 00000.mpls ...) identification code.For example, when the specific title in the CD was reproduced by specific playlist file " 00000.mpls ", the filename with the search file of configured in English that is used to search for content information in the corresponding title was indicated as " esmt_eng_0000.xml ".
Fig. 2 D illustrates the another example according to file structure of the present invention. in this example, comprised under the single root directory be used to manage the reproduction of carrying out by java applet catalogue (promptly, BDJ), be used to manage the HDMV title reproduction catalogue (promptly, BDMV), and metadata catalog (META). more specifically, the catalogue (BDJ) that is used to manage the reproduction of being carried out by java applet comprises index file (index.bdj) and obj ect file (JavaObject.bdj), and comprise and contain java applet file (PPPPP.jar,) catalogue (JAR). the catalogue (HDMV) that is used to manage the reproduction of HDMV title comprises index file (index.bdmv) and obj ect file (MovieObject.bdmv), and comprise above-mentioned playlist directory (PLAYLIST), clip information directory (CLIPINF), stream catalogue (STREAM), and auxiliary data directory (AUXDATA). metadata catalog (META) comprises the search file with filename " esmt_LLL_xxxxx.xml " shown in Fig. 2 C. in the file structure shown in Fig. 2 D, even can not get in specific optical recording and/or the transcriber 10 supporting by being reproduced in of java applet execution, otherwise also can only reproduce the HDMV title by the BDMV catalogue., when being reproduced in particular optical record and/or the transcriber 10 when supported of being carried out by java applet, Java title and HDMV title all can reproduce by the BDJ catalogue.
Fig. 3 illustrates the exemplary configurations of the information that is associated with the above-mentioned file structure (Fig. 2 A is to shown in the 2D) that is recorded in the CD.More specifically, from the inner ring (or center) of dish, coil and comprise the AV stream zone that occupies the file system information area of coiling penetrale, occupies the outermost portion of coiling and occupy file system information area and flow database area between the zone.In file system information area, write down the system information that is used to control entire data files.And, be recorded in the stream zone such as master datas such as audio/video/graphic data.Such as index file, obj ect file, play list file, clip information file and meta data file etc. be used for reproducing recorded flow data (
*.m2ts) file is recorded in the database area of coiling.
As mentioned above, according to the present invention, dynamic image content can be registered as the data in the stream zone that is recorded in the CD.And the information that is used for the searching moving picture material is recorded in the search file as meta data file.In addition, record is used for reproducing the used zone of fileinfo that is recorded in the dynamic image content that flows the zone and is called " management area ".This zone is corresponding to file system information area shown in Fig. 3 and database area.At this, each zone shown in Fig. 3 only is exemplary, so the arrangement in each zone is not limited to the structure shown in Fig. 3.
Fig. 4 illustrates file structure and the relation thereof that is recorded in according to an embodiment of the invention on the CD, so that by using this document structure to reproduce data.In other words, Fig. 4 illustrates the relation of the specific title of being reproduced to the file structure shown in the 2D by Fig. 2 A.Particularly, this figure describes the relation of the corresponding title that is reproduced in detail when the user makes title reproduction command to the specific title that offers the concordance list that disposes based on index file.
To provide the optical recording that to support java applet and/or an example of transcriber 10 with reference to figure 4.And in this case, index file uses Java index file (index.bdj).This index file (index.bdj) comprises " at first playing " information, " top menu " information and at least one " title " (that is, title # 1 is to title #4) information.At this, title (that is, title # 1 is to title #4) can be made of in HDMV title and the Java title any one.Correspondingly, each title (title # 1 is to title #4) comprises the information of the attribute of indicating each title.At this, each title comprises " Title_feature () " field, " Title_jobj_id_ref () " field (or " Title_jobj_id_ref () "), " Title_descriptor_ref () " field and " Enhanced_search_info_ref () " field.The feature of " Title_feature () " field indication title, and " Title_mobj_id_ref () " field (or " Title_jobj_id_ref () " field) indication has the special object of the reproduction script information of corresponding title." Title_descriptor_ref () " field is indicated the attribute of corresponding title, and " Enhanced_search_info_ref () " field is specified the search file that comprises the search information in the corresponding title.
More specifically, " Title_feature () " field comprises " Title_environment " information, " Title_playback_type " information and " Title_link " information.It is to be carried out by java applet or moving image HDMV that " Title_environment " information is indicated reproduction (or playback) environment of corresponding title.The attribute of the title that " Title_playback_type " information indication is reproduced be the motion picture films title or for the title of user interactions use.Whether " Title_link " information indicates corresponding title to be linked with another title of different attribute.For example, if corresponding title is the HDMV title, then whether " Title_link " information indicates this title to be linked with the Java title.Otherwise if corresponding title is the Java title, then whether " Title_link " information indicates this title to be linked with the HDMV title.
Above with reference to figure 2A in the file structure of 2D explanation in the middle of the included search file, the search file name that comprises the search information that is associated with corresponding title is recorded in " Enhanced_search_info_ref () " field. for example, this search file name is recorded in one of " ESI_filename_1 () " and " ESI_filename_2 () ". correspondingly, when later user selects to comprise the specific title of above-mentioned heading message, corresponding title reproduced in process afterwards (or playback). will describe the relation of the title that is reproduced in detail now.
When the user (for example selects to reproduce specific HDMV title, title #1) time, according to reproducing particular play list (for example, 00000.mpls) by special object (for example M-OBJ 1) defined order or program in the movie object file (MovieObject.bdmv) of " Title_mobj_id_ref () " field appointment included in this heading message.And, specific clips (by "
*.clpi " and "
*.m2ts " constitute) reproduce by the broadcast item in this playlist.Perhaps, when the user (for example selects to reproduce specific Java title, title #3) time, according to (for example by the special object in the specified Java obj ect file (JavaObject.bdj) of " Title_jobj_id_ref () " field included in this heading message, J-OBJ 1) defined order or program reproduce particular play list (for example, 00000.mpls).And, specific clips (by "
*.clpi " and "
*.m2ts " constitute) reproduce by the broadcast item in this playlist.Each object in the Java obj ect file (JavaObject.bdj) (for example, J-OBJ1, J-OBJ2 ...) comprise carry out specific java applet file (
