Relevant for this, " master data " among the present invention means general data or the information on the recording medium (for example CD), and for example the creator offers user's the video and the title of voice data, generally with the MPEG2 format record, and is commonly called main AV stream.
Append or supplementary data mean relevant with master data, offer the user so that all data of reproducing for example comprise the auxiliary audio stream of music as a setting; Interactive graphics stream such as ejecting (PopUp) menu, with click (click) sound of user interactions; And such as captions (subtitle) information of explanatory note (caption) information and the lyrics.
Therefore, according to the character of supplementary data, supplementary data is recorded into and main AV data multiplex with the MPEG2 form, or is the stream file that is independent of main AV stream with MPEG2 or other format record.
Caption information is when the user selects the captions of the language that recording medium supports and plan to watch video (main AV data) with the explanatory note of this language, is generally shown at the information of screen one side.
Being introduced into the character according to the data in the reproduction units that is associated provides the popup menu of different menu to provide in a wicket of display screen and does not change the menu information of the picture reproduction in the reproduction.Popup menu can cover on the picture in the reproduction and show.Therefore, this menu information is called as " ejection " menu.
Click sound is at the choice menus button or the of short duration sound that provides when selecting is provided, attracts user's the fact of notice to inform that selection has been made.According to the purposes of click sound, click sound is called as " menu sound " sometimes.
In the present invention, " captions " of data can be caption information, present graphical information etc. as a supplement, for example the lyrics of a first song.Therefore, captions can be write as various forms, such as the bitmap form or the text data (for example character data) of MPEG2 transmission (TS) grouping, binary format.Captions with the text data format record are called as " text subtitle ".
Be elaborated to being used for master data and supplemental data be recorded in such as form on the recording medium of BD dish and the file structure that is used for management data below in conjunction with Fig. 1 and Fig. 2.
Fig. 1 illustrates the file structure that is used to manage various data on the disc according to the embodiment of the invention.As shown in the figure, at least one BD catalogue BDMV is present under the root directory.In BD catalogue BDMV, include as general file (upper file) to guarantee index file index.bdmv and the obj ect file MovieObject.bdmv with user interactions.In addition, playlist directory PLAYLIST, clip information directory CLIPINF, stream catalogue STREAM and auxiliary data directory AUX DATA are comprised among the BD catalogue BMDV.
According to specific format be recorded in being called as in the disc file of the video of " main AV stream " and audio stream and for example the auxiliary flow of text subtitle (hereinafter being referred to as text subtitle stream) have an independent existence in stream catalogue STREAM.Because text subtitle stream files and AV stream file are with MPEG2 form (for example MPEG2 transmission grouping) record, " * .m2ts " is used as the extension name (for example 01000.m2ts, 02000.m2ts and 10001.m2ts) of each stream file.Perhaps, if text subtitle stream files, because text subtitle stream has the auxiliary or supplementary data feature that is different from for example main AV stream, can be with " txtst " as file extension.
In the BD standard, stream can be called as clip stream file.Related to the present invention, text subtitle data exists with the form of the stream file that separates with the AV stream file.As shown in Figure 1, text subtitle data is as text subtitle stream files 10001.m2ts (not shown) or 10001.txtst (not in shown in the STREAM catalogue, but only for illustrative purposes and in shown in the AUX DATA catalogue) and exist.
Clip information (or clipinfo) catalogue CLIPINF comprises clip information or clipinfo file * .clpi, and each file and stream file have one-to-one relationship.Clip information file * .clpi has the attribute information and the time sequence information of respective streams file and is used as management document.More specifically, the information in the clip information file comprises the feasible map information that time stamp (PTS) can be mapped to the source packet number (SPN) of source grouping in the respective streams file that presents.This mapping is called as the mapping of entry pointer or " EP_map ".
Stream file and corresponding clip files can be collectively referred to as " montage ".Therefore, the file among the clip information directory CLIPINF " 01000.clpi " has attribute information and the time sequence information about the file " 01000.m2ts " among the stream catalogue STREAM, and file " 01000.clpi " and " 01000.m2ts " constitute montage.
Playlist directory PLAYLIST comprises play list file * .mpls, and each listing file has at least one broadcast of specifying specific clips broadcast item PlayItem at interval.Play a PlayItem and comprise about the play start time In-Time of playback specific clips and the time sequence information of broadcast concluding time Out-Time, and by in the Clip_Information_File_name field, providing the clip information name to identify this montage.Use the PTS information in In-Time and the Out-Time information, the EP mapping of the clip information file of being named allows the searched and acquisition in position (for example SPN) of special flow address or respective streams file, and the reproduction of playlist causes the reproduction of montage thus.
By providing at least one to play a PlayItem, play list file * .mpls is as the basic management file of playing the montage of wanting.In addition, playlist * .mpls also can provide a son to play a SubPlayItem to manage for example reproduction of supplementary data, and the reproduction of supplementary data can be synchronous or asynchronous with a broadcast PlayItem.For example, under the situation that comprises the SubPlayItem that is used for the playback text subtitle, corresponding SubPlayItem and PlayItem are synchronously with these data of playback, yet, comprising when being used for playback and can browsing the SubPlayItem of voice data of slide show, corresponding SubPlayItem is not synchronous with PlayItem.
In the present invention, comprise that the auxiliary data of text subtitle or supplementary data for example can be managed by SubPlayItem, this will be elaborated below.
Auxiliary data directory AUX DATA is the zone of writing down the auxiliary data file that playback uses separately.For example, in order to support more user-friendly playback, can will provide the audio files Sound.bmdv of click sound, the font file * .font that in text subtitle playback, is adopted etc. to be recorded in wherein.
Therefore, the text subtitle stream 10001.txtst as a kind of auxiliary data can be recorded in auxiliary data directory AUX DATA as illustrated in fig. 1.
In addition, in above-mentioned BD catalogue BDMV, index file index.bdmv and obj ect file MovieObject.bdmv exist with the interactivity of assurance with the user as general file.Index file index.bdmv has provides the menu information that the user can select and the concordance list of heading message.MovieObject.bdmv provides navigation command for example carrying out playlist, and can call according to the selection of making in concordance list.
As shown in Figure 2, the disc capacity of BD-ROM is organized into file system information area, database community He Liu district.File system information area stores is used to manage the system information of disc.Database community comprises general files area and playlist and clip information area.The general file of general files area stores such as index.bdmv file and MovieObject.bdmv file.Playlist and clip information area stores PLAYLIST catalogue and CLIPINF catalogue.Master data and supplementary data (STREAM catalogue and AUXDATA catalogue) are recorded in the stream district.By this, transcriber is determined master data and the supplemental data that will reproduce by using fileinfo in the database community and/or the flow management information in the stream district.
Therefore, via the flow management information in the fileinfo in the database community and/or stream file district (the stream district), definite master data and the auxiliary data and their reproducting method that will reproduce of user.
In the explanation of back, will set forth being used to manage, and the method for the supplementary data of the management information that will write down record and playback management information and use makes an explanation such as the management information data structure of the reproduction of the supplementary data of text subtitle.
Fig. 3 illustrates the data structure and the method for the playback management information that is used to write down main AV data and supplementary data stream.As shown in the figure, the specific title that is used to reproduce can be managed by play list file PlayList, and main AV data are recorded in (not shown) among the main montage Main Clip.More particularly, in this embodiment, this main montage Main Clip can be by a plurality of broadcasts PlayItem#1 and PlayItem#2 management.Equally, different main montage Main Clip can be by the management of a plurality of broadcasts among the playlist PlayList.
The supplementary data of replenishing as main AV data is recorded in the independent montage and by sons such as for example SubPlayItem# 1, #2, #3 plays a management.As shown in the figure, there is a SubPath in each supplementary data type, and son broadcast item can be organized by SubPath.
That is, play a management supplementary data with the supplementary data classification and by a plurality of sons according to clip type.For example, the audio clips (for example Korean or English) that can browse slide show can be one and play a montage of SubPlayItem#1 management by among the SubPath first, plays a montage of SubPlayItem# 2 management and support explanatory note (caption) information of Korean, English, Japanese can be one respectively by the son among another SubPath.In the supplemental data, a plurality of other montages except that audio clips and text subtitle clip (for example PopUp etc.) can be play a SubPlayItem#3 management by the son among the another SubPath.
Therefore, an example file structure of the present invention has the structure that montage is wherein managed by the son broadcast (for example, each supplementary data or SubPath type) of each clip type.
Broadcast item PlayItem among the PlayList has the playback management information that is used to reproduce master data, and a son broadcast SubPlayItem has the playback management information that is used to reproduce supplementary data.Especially, as mentioned above, as the part of playback management information, broadcast item and son are play item and are provided reproduction start time In-Time and reproduction end time Out-Time for each montage that is associated.
The figure of the embodiment of the text subtitle of wherein main AV stream and supplementary data-especially-provided simultaneously is provided for Fig. 4 A and Fig. 4 B.Shown in Fig. 4 A is that text subtitle is the example of the caption information of Korean, and shown in Fig. 4 B is that text subtitle is the example of English letter descriptive information.Korean text captions and English text captions exist as independent montage, and select to be shown in a side of indicator screen based on the user, with main AV flow point from and overlap with main AV stream.
Below, will the grammer of the data structure of all embodiments according to the present invention be described.
Fig. 5 illustrates the figure of ProgramInfo () the data structure grammer that is used for the supplementary data clip information according to an embodiment of the invention.Equally, Fig. 5 also provides the method in a kind of clip information of using son to play to select the method for montage and language message is covered text subtitle clip according to the attribute information in the montage.As shown in the figure, clip information file zzzzz.Clpi use five data structure objects ClipInfo (), SequenceInfo (), ProgramInfo (), CPI () and ClipMark () provide application message and the temporal information about each stream file * .m2ts, * .txst etc.In five data structure objects of clip information file zzzzz.Clpi, ProgramInfo () data structure has length field and " number_of_program_sequence " field.Length field is represented the length of ProgramInfo data structure, the program sequence number that the indication of " number_of_program_sequence " field is managed by the program information data structure.For by 1 each program sequence that carries out index, data structure comprises " SPN_program_sequence_start[1] " field, one " program_map_PID[1] " field and one " number_ of_streams_in_ps[1] " field." SPN_program_sequence_start[1] " field is indicated the 1st source that program sequence is initial grouping (SPN)." program_map_PID[1] " field represents to comprise the pid value of transmission grouping of the program_map_section of the 1st program sequence.
" Number_of_streams_in_ps[1] " field is represented the 1st the basic fluxion in the program sequence.Carry out the stream of index for each by stream_index, data structure also comprises " stream_PID (1, stream_index) " field, one " StreamCodingInfo (1, stream_index) " data structure etc.Stream_PID[1] (stream_index) data structure indication is by the pid value of the basic flow transmission grouping of the stream index stream_index appointment of the program sequence of sequence index 1 appointment." StreamCodingInfo (1, stream_index) " data structure has the coded message of the basic stream that flows about main AV stream and supplemental data.
Have " length " field that " StreamCodingInfo (1; stream_index) " data structure about the coded message of basic stream comprises indication " StreamCodingInfo (1; stream_index) " field length, and " stream_coding_type " field of the type of coding of the basic stream of indication.Back one field has the coded message about the various forms of streams of the type of coding that depends on basic stream.
For example, the stream_coding_type of 0x02 represents the coded message of MPEG2 video flowing, the coded message of the stream_coding_type indication HDTV LPCM audio frequency of 0x80, the stream_coding_type of 0x81 represents the coded message of Doby AC-3 audio frequency, the stream_coding_type of 0x91 represents the coded message of interactive graphic stream, the stream_coding_type of 0x90 represents to present the coded message of graphical stream, and the stream_coding_type of 0x92 represents the coded message (for ease of explanation, Fig. 5 illustrates the situation that stream_coding_type is 0x02 and 0x92) of text subtitle stream.
Under the situation of stream_coding_type=0x02, provide video_format, frame_rate, aspect_ratio, cc_flag and ISRC () field.First three field is readme, and whether information is comprised in the stream row 21 (Line 21) of cc_flag indication 525/60TV system, and the ISRC field is indicated ISRC applicatory.
Under the situation of stream_coding_type=0x92 (that is, being under the situation of text subtitle stream), in can will being included in about the language message of text subtitle clip by use " textST_language_code " field." textST_language_code " field is used the language of the code word indication captions of 8*2 position.
As mentioned above, by language message being inserted in the text subtitle clip information by language_code, can at first search and store the clip information of text subtitle, and it is used for being reproduced in selectively subsequently the language subtitle that the user wishes in the reproduction process of for example main AV data.
This method can be used to selecting being play between a plurality of montage of management by single son, as selection can browse the audio clips of slide show language, select the situation of the language of text subtitle.Fig. 6 illustrates the data structure grammer of the son broadcast item of the example according to the present invention.As shown in the figure, the grammer of son broadcast " SubPlayItem (1) " comprising: indication is play the length field of item length; Sign is play " Clip_Information_file_name[0] " field of first clip information file of the montage of management or unique clip information file by son; Specify " SubPlayItem_IN_time " field and " SubPlayItem_0UT_time " field of aforesaid stream file start time and concluding time; Have according to IS0646 value " Clip_codec_identifier[0] " field for " m2ts "; Be used to indicate " ref_to_STC_id[0] " field of stc_id value of the STC sequence of montage; Even and if effectively sub item and broadcast synchronous " sync_PlayItem_id " field and " sync_start_PTS_of_PlayItem " field play.
Sub-playitem syntax also comprises a bit information field that is called as " is_multi_Clip_entries ", and this information field is recorded thereon to play an information of managing as discerning whether a plurality of montages of supplemental data by son.For example, when " is_multi_Clip_entries "=1b, son is play an a plurality of montage of management, and when work as " is_multi_Clip_entries "=0b, and son is play and managed a montage.
(i.e. " is_multi_Clip_entries "=1b), then the grammer of son broadcast item also comprises an indication " num_of_Clip_entries " field by the montage number of a son broadcast management as a plurality of montages of fruit broadcast item management.When the management be a plurality of montage the time, these montages are called as sub-montage in sub-playitem syntax.For second montage (being subclip_entry_id=1) sub-montage to the end, the grammer that son is play provides " Clip_Information_file_name[subclip_entry_id] " field, " Clip_Codec_Identifier[subclip_entry_id] " field and " ref_to_STC_id[subclip_entry_id] " field.This information of first montage has been provided in the first of sub-playitem syntax when index (for example subclip_entry_id) is " 0 ".
In addition, if for example son broadcast item is being managed text subtitle, the son of then serving as reasons in sub-playitem syntax is play each montage of managing and is comprised " language_code " field.Therefore, the language message of the sub-montage of sub-montage entry identifier=0 is by " language_code[0] " field record, and the language message relevant with the remaining a plurality of text subtitles during son is play is by " language_code[subclip_entry_id] " record, as shown in Figure 6.The language codes indication of sub-montage is by the language of the text subtitle of sub-montage representative.
According to above-mentioned data structure and method, wherein express the various language montages of text subtitle, and clearly, " language_code " field can be used for speech selection information is offered the user to select and the reproduction text subtitle.
Therefore, " language_code " field not only is used to provide the language message of text subtitle, also is used to provide information so that play the attribute of item and be selected to possibility in a plurality of montages according to son.
Fig. 7 illustrates the data structure grammer of son broadcast item according to another embodiment of the present invention.Except that having saved language codes, the grammer of Fig. 7 is identical with the grammer of Fig. 6.In addition, in the embodiment of Fig. 7, by the content that changes " Clip_information_file_name[0] " field and " Clip_codec_identifier[0] " field with the title of a rule application in each clip files.In general, filename " nnnnn " (0≤n≤9) is provided in " Clip_information_file_name[i] " field, and " m2ts " is provided in " Clip_codec_identifier[i] " field.Yet, according to this embodiment of the invention, when group is play item management text subtitle, " xxnnn " is provided as " Clip_information_file_name[i] " field, and wherein " xx " is that language codes (ISO 646) and " text " of two bytes is provided in " Clip_codec_identifier[i] " field.Another example is, " xxnnn " and " demonstration " that can browse in the audio clips example of demonstration can be respectively inserted in two fields.
Therefore, according to this data structure, reproduce the method for playing the montage that item managed by son selectively and have by for example using language message (under the situation of text subtitle) in " Clip_information_file_name[i] " field and " Clip_codec_identifier[i] " field to distinguish the advantage of file.In addition, this information can be used between the type of playing a supplementary data of management or montage by different sons, realizing distinguishing.
Fig. 8 illustrates the part of the data structure grammer of playing " STN_table () " in the item, and the data structure grammer of " stream_entry () " in " STN_table () " is shown.As shown in Figure 8, the grammer of broadcast item comprises the STN_table () of the tabulation of selectable basic stream in the definition broadcast reproduction process.
For example, Fig. 8 illustrates " STN_table () " definable video-frequency basic flow (for example main AV stream video), audio frequency and flows (audio frequency of for example main AV stream), text subtitle substantially and present that picture flows substantially, mutual picture flows substantially etc.More particularly, " STN_table () " has " stream_entry (id) " data structure to every type basic stream.Each " stream_entry (id) " data structure is distinguished from each other out by index identifier " id ".
The grammer of " stream_entry (id) " data structure comprises " type " field, and its indication " stream_entry (id) " is towards the main AV stream of being managed by the broadcast item or towards play a supplementary data stream of managing by son.In other words, " type " field designation data stream is by playing a use or being used by subpath.For example, in one embodiment, when " stream_entry (id) " is during towards main AV stream, " type " is set to 1, is during towards supplementary data stream and work as " stream_entry (id) ", and " type " is set to 2.
When " stream_entry (id) " when equaling 1 " type ", " stream_entry (id) " comprises " ref_to_stream_PID_of_mainClip " field of the PID (packet identifier) in the transmission grouping of the main AV stream of indication.
When " stream_entry (id) " is that " stream_entry (id) " comprises " ref_to_SubPath_id " field, " ref_to_subClip_entry_id " field, " ref_to_stream_PID_of_subClip " field and " language_code " field when equaling 2 " type ".The affiliated subpath identifier of stream that " ref_to_SubPath_id " field provides a son to play item and be associated with this " stream_entry (id) "." ref_to_subClip_entry_id " field is indicated the sub-montage entry id of this stream, as top discuss in conjunction with Fig. 6.When this stream flowed for MPEG2, the indication of " ref_to_stream_PID_of_subClip " field formed the PID of the transmission grouping of the supplementary data stream that is associated with this " stream_entry (id) ".The language of the supplementary data stream that the indication of " language_code " field is associated with this " stream_entry (id) ".
Therefore, by being included in " STN_table () " of playing in the item, playing item and comprise the information of discerning the main AV stream of playing item and the supplementary data stream that is associated with main AV stream.By " STN_table () ", the broadcast item also comprises the information about the language of being supported by every type supplementary data stream; For example interactive graphics stream, caption stream etc.In addition, this language message can be used as the method for selection by the supplementary data stream of the language of user's request.
As can understanding, " language_code " field can be used to be provided at by son plays the information of selecting between a plurality of different language montage of being managed.
As mentioned above, embodiments of the invention have a kind of data structure, and wherein a plurality of montages have an independent existence and play item by son and manage, thereby make a son play a supplementary data of each type of management.
