With above content relatively, the master data among the present invention is for example represented the heading message on the CD, offers user's video and voice data such as the author, generally presses the MPEG2 format record, and also often is called main AV stream.
The data relevant with master data of reproducing for the convenience of the user and providing are provided additional or auxiliary data.Supplementary data comprises that caption information, interactive graphic information (for example, menu information) or the like with multiplexed MPEG2 format record in main AV stream, perhaps are recorded in the stream file that does not rely on main AV stream by MPEG2 form or extended formatting.
Therefore, supplementary data in the present invention refers to carries out the data of additional mission to help master data to reproduce, such as explanatory note (Caption) information.Caption information for example can be that caption information is presented at a kind of caption information form on the screen when the user watches the selected language-specific captions of video (main AV data).
Introduce Pop-up (PopUp) menu and provide concrete menu information with data attribute according to the specific reproduction unit.Pop-up menu is the image information by providing with the overlapping wicket form of current reproduced image in some cases.This menu information just is called as Pop-up.
Term is clicked (Click) sound and is referred to and attract the user's attention so that the brief sound that the user makes a choice by the mode of selecting such as menu.When selecting or activate file public of the sound that provides be " clicking sound " or " menu sound " _.
The captions of data refer to the presentation graphic such as the caption information or the lyrics as a supplement.Therefore, can use various forms to write captions, such as the bitmap form that uses MPEG2 transmission (TS) grouping, binary format, text data etc., and the captions that are recorded as the text data record can be called as text subtitle.
Fig. 1 shows the file structure of high density compact disc according to an embodiment of the invention.As shown in the figure, file structure comprises at least one BD catalogue BDMV under root directory, and this BD catalogue comprises that index file index.bdmv and file destination MovieObject.bdmv are as the general file (top file) of guaranteeing user interactivity.Index file index.bdmv is built into the central authorities of the concordance list that has at user option menu information and heading message.This BD catalogue also comprises playlist directory PLAYLIST, clip information directory CLIPINF, stream catalogue STREAM and exports multiplexed catalogue OUT MUX.
Stream catalogue STREAM has about being recorded in the file of interior main video of MPEG2 transmission grouping and audio stream (being also referred to as main AV stream).Because main AV stream is with the MPEG2 format record, the extension name of main AN stream file (01000.m2ts and 02000.m2ts) is " * .m2ts ".
Simultaneously, in independent catalogue, promptly be provided as the additional or auxiliary data flow that during reproducing master data, makes things convenient for the user and use in the OUT MUX catalogue.OUT MUX catalogue has replenishes and auxiliary data flow, such as text subtitle (10001.txtst, 20001.txtst), main body (10001.font, 20001.font), (Pop-up) menu (30001.popup), click sound (Sound.bdmv) or the like.(for example, text subtitle) supplementary data is relevant with main AV stream, and is subjected to support such as the auxiliary data of audio files and font file such as interactive graphics (IG) (for example, pop-up menu) and captions.For example, audio files comprises and is relevant to the sound of clicking that the user reproduces when pop-up menu is selected, and font file comprises the font that is used to reproduce text subtitle.Replenish with auxiliary data flow not multiplexed with primary traffic.
When replenishing and auxiliary data not with management is described replenishes and during auxiliary data, management document and mistake just are easy in the multiplexed independent catalogue of primary traffic.
For example, usually be not real time data replenish and auxiliary data can be preloaded into impact damper and manages with convenience file.
Clip information directory CLIPINF has the clip information file (for example 01000.clpi and 02000.clpi) one to one with each stream file and some OUT MUX file * .m2ts and * .txt.Especially, clip information file * .clpi has the attribute information and the timing information of associated documents.Timing information comprises the information that is mapped to the source packet number of the source grouping in the stream file about the demonstration timestamp (PTS) with the data in the file.Usually, this mapping is known as the entrance mapping.In the BD standard, AV stream * .m2ts, * .txt file etc. and the clip information file * .clpi that is associated jointly are called " montage ".
Broadcast at least one broadcast item at interval that playlist directory PLAYLIST comprises play list file (* .mpls) and is used to specify specific clips.Therefore, the broadcast item has the information about the play start time In-Time of the specific clips of expecting to play and broadcast concluding time Out-Time, is promptly specified by the clip name Clip_Information_File that plays in the item.Play list file * .mpls is used for playing the basic played file information of the montage of expectation by providing at least one to play item.In addition if necessary, just provide son to play item to play list file * .mpls.Except play a montage of management by son is the file in the OUT MUX catalogue, and son is play and provided information same as described above for playing item.
