Realize best mode of the present invention
Now will be in detail with reference to the preferred embodiments of the present invention, its example is shown in the drawings.In any possibility part, will in institute's drawings attached, use identical label to refer to identical or same part.In addition, though the term of Shi Yonging is selected from known and used term in the present invention, but some term of mentioning in instructions of the present invention is selected by his or her judgement by the applicant, and its detailed meaning is described in the relevant portion of this instructions.In addition, require also will understand the present invention by the meaning that each term includes not just by employed actual terms.
According to the present invention, " reproduction management document " refers to be used for reproducing recorded data and the local management document of storing the data of being stored on the recording medium.More specifically, in Blu-ray disc (BD), reproduce management document and be called as " playlist ".Carry out reproducing the detailed description of management document with reference to Fig. 2 A and Fig. 2 B and to the explanation of whole file structure.In other words, though " playlist " refers to the reproduction management document in the present invention, it is evident that and to use different terms to the recording medium of the various criterion except that Blu-ray disc (BD).Yet, it is evident that equally the technical scope of other recording medium does not deviate from scope and spirit of the present invention.
Fig. 1 illustrates total view of the present invention.More specifically, Fig. 1 illustrates the example that optical recording and/or transcriber 10 and other external device (ED) are used in combination.Therefore, " optical recording and/or transcriber 10 " can be recorded in data on the CD of various standards and/or from it and reproduce data.Depend on its design, the CD (for example, Blu-ray disc (BD)) that this device can only be recorded in data specific criteria upward and/or from it reproduces data, and perhaps this device can be only from the optical disc replay data.Yet, consider that Blu-ray disc (BD) standard is left to be desired and Blu-ray disc (BD) and other peripherals related, will provide and reproduce Blu-ray disc (BD) and go up the blu-ray player (BD player) of recorded data or data are recorded in blu-ray disc recorder (BD register) on the Blu-ray disc (BD) as the example of optical recording according to the present invention and/or transcriber 10.It is evident that equally " optical recording and/or transcriber 10 " can be called as " driver " that can be equipped in the computing machine.
Except record and/or reproduce the function of CD, also have the external input signal of reception and handle received signal and by treated signal is sent to the function that signal is provided to spectators on the screen via display 20 according to optical recording of the present invention and/or transcriber 10.In this case, without limits to the external signal that can import.Yet modal external input signal is digital broadcast program (DTV) or the Internet.The most especially, because the medium that the Internet is the public to be easy to visit, so the user can utilize this data by downloading the particular data that is provided on the Internet via optical recording and/or transcriber 10.When master data is recorded in the CD that is loaded in optical recording and/or the transcriber 10 (promptly, BD) time, and when existing in such as external sources such as the Internets with subdata that master data is associated, the present invention manages to reproduce data effectively by making up master data and subdata.
In order to simplify explanation of the present invention, " master data " refers to be recorded in the signal in the CD, and " subdata " refers to be present in the signal in the external source of CD outside.Yet these terms only are based on the method for obtaining data, and master data and subdata do not only limit to data the data of particular type.Therefore, master data generally includes voice data, Presentation Graphics (PG) data, text subtitle, interactive graphics (IG) (IG) data etc.And be not limited to above-mentioned example, the data that are present in other type that is associated with master data in the external source can be used as subdata.In the present invention, provide " interactive graphics (IG) (IG) " and " text subtitle " example as the subdata of being reproduced.
More specifically, the video/audio stream (AV stream) of supposing particular film is recorded on the CD as master data.Suppose that also " interactive graphics (IG) (IG) stream " that is associated with this AV stream is present on the Internet as subdata.Thereby the user may wish to download the interactive graphic stream as being present in the subdata on the Internet, wishes that then the IG stream included AV stream in master data that will be downloaded reproduces.In order to satisfy user's demand, need to determine related between AV stream and the interactive graphic stream that institute downloads and store in the CD, also need to manage (or control) requiredly and reproduce the systems approach of these data (that is, AV flow and IG flows) as the user.
Fig. 2 illustrates an example of interactive graphic stream shown on the same screen and AV stream.Usually, AV stream is displayed on the whole screen.On the contrary, interactive graphic stream only is displayed on interior little the zone (being called " object " again) of screen.Interactive graphic stream can or be provided by the master data that is write down in the CD (for example, main interactive graphic stream), is perhaps provided by the subdata of downloading from external source (for example, auxiliary interactive).
In order to satisfy user's demand, the file structure that master data and subdata (the most especially, auxiliary interactive) need be associated is elaborated to it with reference to Fig. 3 A to 3C.
Referring to Fig. 3 A, it shows the file structure that is used for the information that console panel writes down, and comprises at least one BD catalogue (BDMV) in the root directory (root).Each BD catalogue comprises representative " index.bdmv " and " MovieObject.bdmv " of employed general file with one or more user interactions the time.Each BD catalogue comprises four file directorys that comprise the data that will reproduce and reproduce the required information of these data.Included file directory is in each BD catalogue: auxiliary data directory (AUXDATA), stream catalogue (STREAM), clip information directory (CLIPNF) and playlist directory (PLAYLIST).
Auxiliary data directory (AUXDATA) comprises such as " Sound.bdmv " file, " aaaaa.otf " file etc. reproduces the required additional data file of CD." Sound.bdmv " file provides sound when carrying out interactive graphics (IG) (IG) stream, and " aaaaa.otf " file provides font information when the reproduction dish.Stream catalogue (STREAM) comprises AV stream file and interactive graphic stream files.More specifically, each stream generally is the form with MPEG2 transmission grouping.In the BD standard, above-mentioned each stream is called as clip files.Referring to Fig. 3 A, among stream file, the AV stream that " 01000.m2ts " expression is multiplexed with interactive graphic stream, the independently AV stream that " 02000.m2ts " expression is not multiplexed with any interactive graphic stream, and " 10001.m2ts " expression interactive stream.
In addition, clip information directory (CLIPNF) comprises and flows each stream file (clip files) included in catalogue clip information file (for example, 01000.clpi, 02000.clpi, 10001.clpi) one to one.Clip information file ( *.clpi) comprise the attribute information and the timing information of stream file (clip files).In the BD standard, mutually one to one every couple of AV stream ( *.m2ts) and corresponding clip information file ( *.clpi) be designated as a montage.Therefore, included " 01000.clpi " in the clip information directory (CLIPINFO), in " 02000.clpi " and " 10001.clpi " each include and correspond respectively to " 01000.m2ts " that be included in the stream catalogue (STREAM), each attribute information and the timing information in " 02000.m2ts " and " 10001.m2ts " file.Therefore, each all forms a montage with " 02000.m2ts " file and " 10001.clpi " with " 10001.clpi " file to " 01000.clpi " and " 01000.m2ts " file, " 02000.clpi ".
More specifically, by " 01000.clpi " and " 01000.m2ts " montage that forms is called as " the AV montage multiplexed with IG ", and the montage that forms is called as " not multiplexed with IG AV montage " by " 02000.clpi " and " 02000.m2ts ".In addition, by " 10001.clpi " and " 10001.clpi " montage that forms is represented only to be can't help by " interactive graphic stream " montage that any AV stream forms.This montage is called as " IG montage ".Equally, in the present invention, " main montage " refer to be recorded in CD on the montage that is associated of master data, and " sub-montage " refer to download and be stored in local storage in the montage that is associated of subdata.
Fig. 3 A that sees you later, playlist directory (PLAYLIST) comprise one or more play list file ( *.mpls), wherein each play list file ( *.mpls) comprise that between the broadcast area of specifying specific clips at least one play.More specifically, play item and comprise presenting beginning and presenting the information of concluding time (entry time and time departure) of the reproduction of specifying specific clips, this can be by the clip_Information_File_name appointment in playing.Therefore, play list file ( *.mpls) expression is reproduced the reproduction units (or playback unit) of (or playback) desired montage from one or more combinations of playing item.Playlist also comprises and is used to reproduce and play item by the son of playing the different data of item data presented.
Fig. 3 B illustrates the relation (or related) between play list file and the main montage.More specifically, play list file comprises having the main path that at least one plays item, comprises the playback management information that is used to reproduce specific AV montage and play item.In addition, as long as need, play list file just comprises comprising the subpath of at least one height broadcast item.Here, son broadcast item comprises the playback management information that is used to reproduce at least one interactive graphic clip (IG#1, IG#2).For example, interactive graphic clip #1 (IG#1) can provide the menu information with configured in English.And interactive graphic clip #2 (IG#2) can provide the menu information with configured in Korean.Therefore, when reproducing the playlist of (or playback) Fig. 3 B, by playing the AV stream in the reproduction of AV montage.Therefore, by with play a nonsynchronous son and play any interactive graphic stream of selecting corresponding among IG#1 and the IG#2.Can be multiplexed or not multiplexed by playing an AV stream of its reproduction of management with it with interactive graphics (IG).And this can be used selectively by the author of CD.
Fig. 3 C illustrate according to of the present invention be recorded in CD on the universal architecture of the information (or data) that is associated of file structure.More specifically, from the inner periphery (or center) of dish, coil and comprise and occupy the inner most file system information area coiled, occupy the outermost stream district that coils and occupied database community between file system information area and flow data district.In file system information area, write down the system information that is used to control entire data files.And in the stream district, write down such as master datas such as audio/video/graphic data.General file, play list file and clip information file in the database community of coiling, have been write down.Therefore, by using the information in the database community, the user can select the stream of this user expectation reproduction, and determines and use the suitable reproducting method of selected stream.
Therefore, if interactive graphic stream and AV stream is multiplexed, and these two streams all are recorded in the CD, and then two streams are synchronous.Yet if the interactive graphic stream that is recorded in the CD is not multiplexed with AV stream, interactive graphic stream and AV stream are synchronous.In addition, be stored in the position (or location) different, because be stored in interactive graphic stream in the local storage so clearly interactive graphic stream is not multiplexed with AV stream with writing down and be stored in AV stream in the CD.Yet, when the user wishes to be stored in the AV stream of interactive graphic stream in being recorded in CD in the local storage when reproducing, the user should be taken into account two streams for synchronously and reproduced situation and two streams be asynchronous and reproduced situation.The present invention manages to provide a kind of and creates the method for preferred playlist and come method of reproducing data and device by the playlist that uses new establishment.Therefore, the playlist of creating according to the present invention is called as " composite ".Yet this term only is used to distinguish the playlist and the already present playlist of new establishment.
Fig. 4 shows according to optical recording of the present invention and/or transcriber 10.This optical recording and/or transcriber mainly comprise: pickup unit 11 is used to reproduce the control information that comprises master data and the fileinfo that are recorded on the CD; Servo control mechanism 14 is used to control the operation of pickup unit 11; Signal processor 13 is used for or will returns to desired signal value from the playback signal that pickup unit 11 receives, but the data-modulated that perhaps will write down becomes the CD tracer signal and sends these modulated data; Local storage 15 is used to store the subdata of downloading from external source; And microcomputer 16, be used for organically controlling aforesaid operations.In addition, controller 12 is downloaded the subdata that is present in the external source and the subdata of being downloaded is stored in this locality according to user command and stores in 15.Then, controller 12 is created a composite that is used for reproducing the master data that is recorded in CD and is stored in the subdata in the local storage 15.Thereafter, according to user command, controller 12 reproduces master data and subdata by using this composite.Demoder 17 is carried out to the final decoding of output data (that is, master data and/or subdata) and to the user according to the control of controller 17 decoded data is provided.In addition, for signal record in CD, scrambler 18 converts input signal the signal (for example, MPEG2 transport stream) of specific format to according to the control of controller 12 and the signal of being changed is provided to signal processor.
This locality storage 15 of storage subdata can also be configured to for example hard disk drive (HDD).And the new composite of creating can or be stored in and is provided with the back in the local storage 15 and uses, or is temporarily stored in the independent dynamic storage and is used.As an example of the present invention, optical recording and/or transcriber are created new composite individually.In another example, when the carrier data were also stored the subdata of being downloaded instantly, this composite also can be downloaded and store.In this case, optical recording and/or transcriber 10 do not need to create another independent composite.In addition, be provided with the back in the local storage 15 and use, then preferably give the playlist higher priority of only managing master data of service recorder in CD if user expectation is stored in subdata and composite.
In the structure shown in Fig. 4, Fig. 5 A and Fig. 5 B, illustrate respectively and be used to reproduce the device of data and be used for method of reproducing data according to optical recording of the present invention and/or transcriber 10.More specifically, when having disc identifier (disc_id) #1, when promptly the CD of disc_id=#1 was loaded, the controller 12 of optical recording and/or transcriber 10 was verified the sign of respective disc by using pickup unit 11 and signal processor 13.Then, whether there is the one group of subdata (S10) that is associated with " disc_id=#1 " in the subdata of being stored in the local storage 15 of controller 12 checkings.
For example, if to " disc_id=#1 ", have 3 auxiliary interactive streams (Aux IG1, Aux IG2, Aux IG3) in the local storage 15, then controller 12 at first is provided with selection one reproduction (or playback) stream (S20) according to user's request or system.In other words, controller 12 can be notified the user, this auxiliary interactive exists as subdata, controller 12 can or only reproduce the master data that is recorded in the dish according to user command or system's setting then, perhaps selects and reproduce to comprise local composite of storing the auxiliary interactive in 15.Therefore, when the user wishes to make up and reproduces when being recorded in the master data in the CD and being stored in subdata in the local storage 15, controller 12 is created a composite playlist file, and uses the composite playlist file of this new establishment to reproduce data (S202).
Therefore, the new composite playlist file of creating is stored in the local storage 15, can reuse this listing file when later reproduction subdata.Fig. 5 A illustrates and composite playlist file is stored in the local storage 15 so that reproduce auxiliary audio stream, the i.e. subdata of " disc_id=#2 " example.Therefore, when in optical recording and/or transcriber 10, having loaded CD with dish ID " disc_id=#2 ", use the composite that has been stored in the local storage 15, and can under the situation that needn't create new composite, carry out the reproduction of data immediately.In addition, as mentioned above, composite also can be downloaded and use.Below with reference to the whole bag of tricks of Fig. 6 A to Fig. 7 H detailed description according to establishment composite of the present invention.
The feature total according to all methods of establishment composite of the present invention will be described now.Comprise in the play list file and be used to make up the fileinfo that reproduces master data and subdata.Here, master data is play item by included at least one in the main path in the play list file and is play item by son included in the subpath and reproduce.And subdata is only reproduced by son broadcast item included in the subpath in the play list file.
In addition, provide interactive graphic stream as an example that can be applicable to the subdata among Fig. 6 A to Fig. 7 H.More specifically, be stored in the local storage auxiliary interactive can be recorded in master data in the different language of the language of main interactive graphic stream dispose.Perhaps, even subdata uses the language identical with main flow to dispose, subdata also can be configured to have different characteristics.Menu information that this specific character can comprise graphic feature, represented by interactive graphic stream etc.In other words, auxiliary interactive or be used for replacing the main interactive graphic stream that is present in CD perhaps is used to append new interactive graphic stream.Perhaps, when not having main interactive graphic stream in the CD, auxiliary interactive can be used for supporting in addition interactive graphics (IG).
In addition, when main interactive graphic stream included in the master data and AV flow when multiplexed, reproduce main interactive graphic stream by playing item.On the contrary, when main interactive graphic stream does not flow when multiplexed with AV, this main interactive graphic stream is identified by son to play the independently IG stream that item reproduces.Therefore, (for example with auxiliary interactive and master data, AV flows and main interactive graphic stream) when reproducing together, will explain in instructions of the present invention that auxiliary IG stream and master data are also reproduced synchronously and auxiliary IG stream is led the step and reproduced this two kinds of situations with master data.
In addition, the fileinfo that is used for reproducing master data and subdata is linked in play list file.Especially, auxiliary interactive is by the independent subpath configuration in the composite.Here, in subpath, create at least one height and play item so that manage the reproduction of auxiliary interactive.Finally, in order to create, the information that is associated with this composite should be pre-stored in the local storage 15 according to composite of the present invention.More specifically, should prepare the information that is associated in advance by the author of CD, from external source this information be downloaded with subdata then.Referring to Fig. 5 A, the required information of composite is created in " information " representative that is stored in the local storage 15.In the method that is used for creating composite according to the present invention, Fig. 6 A to 6E shows when " main interactive graphic stream " is configured to not with the multiplexed independent stream of AV stream, and so that when reproducing this main interactive graphic stream, create the example of another subpath of the reproduction that is used for management " auxiliary interactive " when there being independent subpath.In other words, the example great majority shown in Fig. 6 A to 6E be applied to when " auxiliary interactive " not with master data in included AV stream synchronously (that is, asynchronous) time.Here, the example shown in Fig. 6 A to 6E is not limited only to when AV stream included in auxiliary interactive and the master data is asynchronous.Depend on applied purposes, also can be in auxiliary interactive and master data included AV flow in situation when synchronous and adopt these examples.
Referring to Fig. 6 A, when creating (or configuration) subpath for auxiliary interactive, for each auxiliary interactive is created a single sub path.For example, form among subpath #2, subpath #3 and the subpath #4 each with managed storage separately and respectively in this locality storage 15 auxiliary interactive #1, auxiliary interactive #2 and the reproduction of auxiliary interactive #3.Therefore, the reproduction of the main interactive graphic stream of subpath #1 management accounts in CD.And by using subpath #1 to manage the method for main IG stream identical with described in Fig. 3 B.More specifically, in this example, when having 3 auxiliary interactive in the storage of this locality, as shown in Fig. 5 A, for in these 3 auxiliary interactive each is created a single sub path, make that playing item by corresponding son manages each auxiliary IG stream, thereby create the structure of "=1 son of 1 stream is play item=1 subpath ".Therefore, when reproducing the combinations thereof playlist, can in comprising CD and by the main AV data of main path appointment, be reproduced selectively by subpath #1 any to the interactive graphic stream of subpath #4 appointment.In other words, be recorded in the main interactive graphic stream in the dish and be stored in one of auxiliary interactive in the local storage 15 and can be reproduced selectively.Yet, depend on applied purposes, when auxiliary interactive exists, can reproduce the higher priority of arbitrary auxiliary interactive.
Referring to Fig. 6 B, when creating (or configuration) subpath for auxiliary interactive, a plurality of auxiliary interactive are incorporated into together to manage by single subpath.For example, being stored in auxiliary interactive #1, auxiliary interactive #2 in the local storage 15 and among the auxiliary interactive #3 each plays a #2, son by son respectively and plays a #3 and son and play a #4 and specify.In addition, son is play an item #2, son plays a #3 and a son broadcast #4 specifies by single subpath (for example, subpath #2) is unified.Therefore, the reproduction of the main interactive graphic stream of subpath #1 management accounts in CD.And, manage the method for main IG stream identical with described in Fig. 3 B by using subpath #1.
More specifically, in this example, when having 3 auxiliary interactive in the storage of this locality, as shown in Fig. 5 A, each in the auxiliary interactive plays a #3 by a son broadcast #2, son respectively and a sub #4 that plays specifies.Here, these 3 sons are play item and are integrated creating single subpath (for example, subpath #2), thereby create a structure of "=1 son of 1 stream play ", and this structure also is the structure of " a plurality of sons are play item=1 subpath ".Therefore, when reproducing the combinations thereof playlist, any among chooser path #1 and the subpath #2 carried out reproduction.Then, can selectively any one that play in the item by the son of selected subpath appointment be reproduced in being included in CD and by the main AV data of main path appointment.
Referring to Fig. 6 C, when creating (or configuration) subpath for auxiliary interactive, a plurality of auxiliary interactive are integrated to create single son and play item.For example, auxiliary interactive #1, auxiliary interactive #2 and the auxiliary interactive #3 that is stored in the local storage 15 is integrated to manage reproduction by single son broadcast (for example, son is play a #2).Here, form the son that is included in the single subpath (subpath #2) and play a #2.Therefore, the reproduction of the main interactive graphic stream of subpath #1 management accounts in CD.And the method for managing main IG stream by use subpath #1 is identical with the method described in Fig. 3 B.
More specifically, in this example, when having 3 auxiliary interactive in the storage of this locality, as shown in Fig. 5 A, each in the auxiliary interactive plays a #3 by a son broadcast #2, son respectively and a sub #4 that plays specifies.Here, 3 son broadcast items are integrated to be play (for example, a sub #2 that plays) by single son and specify.Then, son is play item and is included in the single subpath (for example subpath #2), thereby creates the structure of " a plurality of streams=1 son is play item=1 subpath ".Therefore, when reproducing the combinations thereof playlist, any among chooser path #1 and the subpath #2 carried out reproduction.Then, can be selectively will in being included in CD and by the main AV data of main path appointment, reproduce by in the interactive graphic stream of selected subpath appointment any.
In the method that is used for creating composite according to the present invention, Fig. 6 D and 6E show the example that the subpath that will be used for managing the subpath of " main interactive graphic stream " and be used for management " auxiliary interactive " is integrated into single subpath.Referring to Fig. 6 D, a plurality of sons of configuration are play item to manage the reproduction of main interactive graphic stream and auxiliary interactive in single subpath.More specifically, in single subpath, son is play a #1 and is specified a plurality of main interactive graphic streams (main interactive graphic stream #1, main interactive graphic stream #2, main interactive graphic stream #3), manages the reproduction of main interactive graphic stream thus.In same single subpath, for each auxiliary interactive that is stored in the local storage 15 is created sub play (son is play an item #2, son is play a #3, a son broadcast #4), a reproduction of the auxiliary mutual strontium graphical stream of management thus.Therefore, create son and play a #2, son and play a #3 and son and play among the #4 each, with among independent appointment auxiliary interactive #1, auxiliary interactive #2 and the auxiliary interactive #3 each.Here, main interactive graphic stream is configured to play a #1 appointment by son.In other words, configuration is play an item #1 in single subpath, son plays a #2, a son broadcast #3 and son is play a #4.
Referring to Fig. 6 E, the single son of configuration is play item to manage the reproduction of main interactive graphic stream and auxiliary interactive in single subpath.More specifically, main interactive graphic stream and auxiliary interactive being integrated the single son that is used for reproducing management plays (son is play a #1) and is included in single subpath.Therefore, a son broadcast #1 will be recorded in all a plurality of main interactive graphic streams (main interactive graphic stream #1, main interactive graphic stream #2, main interactive graphic stream #3) and a plurality of auxiliary interactive (auxiliary interactive #1, auxiliary interactive #2, the auxiliary interactive #3) integration that is stored in the local storage 15 on the CD, with the reproduction of management interactive graphic stream, thereby create the structure of " all master/auxiliary interactive graphic stream=1 son is play item=1 subpath ".
In the method that is used for creating composite according to the present invention, Fig. 7 A to 7H shows as " main interactive graphic stream " and AV and flows when multiplexed, or when not writing down " main interactive graphic stream " on the CD, create the example of the subpath of the reproduction that is used for management " auxiliary interactive ".In other words, the example great majority shown in Fig. 7 A to 7H are applied to when AV stream included in " auxiliary interactive " and the master data is synchronous.In addition, for synchronously with AV stream included in " auxiliary interactive " and the master data, clearly need to indicate need be in main AV stream that position and the synchronous synchronizing information of auxiliary interactive.This synchronizing information should be play item by son included in the subpath that describes in detail with reference to Fig. 7 A to 7H and provide.Here, the example shown in Fig. 7 A to 7H is not limited only to when AV stream included in auxiliary interactive and the master data is synchronous.Depend on applied purposes, in the situation that flows as AV included in auxiliary interactive and the master data when asynchronous, also can adopt these examples.
Referring to Fig. 7 A, for auxiliary interactive establishment (or configuration) subpath the time, in subpath, create the sub item of playing, wherein each in establishment separately (or configuration) and the main path is play a son that mates correspondingly and is play item.More specifically, by specifying simultaneously a son of playing corresponding in the playlist all to play, can play the main interactive graphic stream of an appointment with being included in the sub-montage and replacing to be included in the main montage and by each by auxiliary interactive that each corresponding son is play an appointment.This has simplified system and has been convenient to the management that each plays item.Therefore, when using the combinations thereof playlist to reproduce CD, video/audio (A/V) signal is provided by the main A/V stream that is recorded in the dish, and main interactive graphic stream is provided by the auxiliary interactive that is stored in the local storage 15.In other words, replace the main interactive graphic stream that is recorded in the CD with the auxiliary interactive that is stored in the local storage 15.
Referring to Fig. 7 B, for auxiliary interactive establishment (or configuration) subpath the time, in subpath, create the sub item of playing, wherein each in establishment individually (or configuration) and the main path is play a son that mates correspondingly and is play item.Yet, be not all to be play Xiang Douke exist the son of coupling to play item.In other words, play by specifying corresponding to the specific son of playing in the playlist, can be included in the sub-montage and when playing an appointment auxiliary mutual by corresponding son graphical stream replace and be included in the main montage and graphical stream when mutual by this specific master who plays the item appointment.Therefore, when using the combinations thereof playlist to reproduce CD, graphical stream is provided by the auxiliary interactive that is stored in the local storage 15 when mutual.Yet when group broadcast item did not exist, interactive graphic stream provided by being included in the main montage and by the corresponding main interactive graphic stream of playing an appointment.Video/audio (A/V) signal is provided by the main A/V stream that is recorded on the CD.
Referring to Fig. 7 C, when the son in create (or configuration) subpath for auxiliary interactive was play item, each in establishment individually (or configuration) and the main path was play a son that mates correspondingly and is play item.Yet, may exist the son of a plurality of couplings to play item to the single item of playing.In other words, in Fig. 7 A and Fig. 7 B, each is play a son that has a coupling play item.On the contrary, in Fig. 7 C, play item to one and exist the son of a plurality of couplings to play item.Here, Fig. 7 C only illustrates a single example of (playing a #1) of playing.Yet clearly of the present invention this also can similarly be applied to other on the one hand and play (play a #2, play a #3).
More specifically, by specifying a plurality of sons of playing corresponding to specific in the playlist to play, can be included in the main montage and by the main interactive graphic stream of playing an appointment with being included in a plurality of sub-montages and replacing by the auxiliary interactive that corresponding a plurality of sons are play an appointment.For example, can replace a main interactive graphic stream that reproduces by playing item #1 reproduction by 2 auxiliary interactive that each section usefulness had different qualities (for example language).Therefore, when using the combinations thereof playlist to reproduce CD, interactive graphic stream is provided by the auxiliary interactive that is stored in the local storage 15.Yet when group broadcast item did not exist, interactive graphic stream provided by being included in the main montage and by the main interactive graphic stream of playing an appointment.Video/audio (A/V) signal is provided by the main AV stream that is recorded on the CD.
Referring to Fig. 7 D, when the son in create (or configuration) subpath for auxiliary interactive was play item, each in establishment individually (or configuration) and the main path was play a son that mates correspondingly and is play item.Yet, may only in segment section, exist in whole reproduction (or presenting) section that item reproduced and play a son of coupling and play by playing.More specifically, in Fig. 7 A, Fig. 7 B and Fig. 7 C, one or more sons are play the whole broadcast of a Xiang Yuyi section coupling.Yet, in Fig. 7 D, only be present in the segment section corresponding to a son broadcast item of playing item.In other words, play by only during segment section, specifying a son of playing corresponding to included specific of playlist, during reproducing whole reproductions section, be included in the main montage and by each main interactive graphic stream of playing an appointment and be included in the sub-montage and alternately reproduced by the auxiliary interactive that son is play the item appointment by corresponding broadcast.
Therefore, because do not require that a reproduction section (or the section of presenting) that son in the subpath plays is identical with broadcast item in the main path, so sub-broadcast Xiang Nenggeng uses auxiliary audio stream diversifiedly.Yet, in this case, form the border between the reproduction (or presenting) of the reproduction (or presenting) of main montage and sub-montage.Here, main montage is reproduced by playing (for example playing a #1), and the reproduction of main montage becomes the reproduction of sub-montage then.In this, even need supporting to make, system also can between interactive graphic stream, carry out seamless presenting at boundary.
Referring to Fig. 7 E, when the son in create (or configuration) subpath for auxiliary interactive was play item, each in establishment individually (or configuration) and the main path was play a son that mates correspondingly and is play item.Yet each son is play item by its corresponding broadcast of a diverse ways coupling.More specifically, in Fig. 7 E, the example that establishment as shown in Fig. 7 A to 7D is play item can be applicable to each broadcast item.For example, play whole section the method (as shown in Fig. 7 A or the 7B) of playing a #1 of replacing, play to replace whole section the method (shown in Fig. 7 C) of playing a #2 and play with a plurality of sons and replace an only a part of method (shown in Fig. 7 D) of whole section playing item #3 and all be applied among Fig. 7 E with son with son.
Referring to Fig. 7 F, when the son in create (or configuration) subpath for auxiliary interactive is play item, the son broadcast item of the whole section of the presenting coupling of establishment individually (or configuration) and playlist.More specifically, by specifying simultaneously a son of playing corresponding in the playlist all to play, play the main interactive graphic stream of an appointment with being included in the sub-montage and replacing to be included in the main montage and by each by the auxiliary interactive that corresponding single son is play an appointment.Therefore, can simplified system.
Referring to Fig. 7 G, when the son in create (or configuration) subpath for auxiliary interactive is play item, the son broadcast item of the whole section of the presenting coupling of establishment individually (or configuration) and playlist.Here, comprising that the son that presents the start time (entry time) and present the information of concluding time (time departure) that reproduces the sub-montage managed about it defines the section of presenting by the time in playing.In the situation of Fig. 7 F, son broadcast item comprises and reproduction (or presenting) is included in the entry time of the main path in the playlist and entry time and the time departure that time departure is complementary.Yet in the situation of Fig. 7 G, son is play item and is comprised a plurality of entry times and time departure.Therefore, each section that is defined as entry time and time departure is called as " time slot ".For example, Fig. 7 G illustrates three time slots " time slot #1 ", " the time slot #2 " and " time slot #3 " that is included in the son broadcast item.Time slot can be created by random section.Yet time slot can also be complementary with broadcast item #1, a broadcast #2 and the broadcast #3 in the main path.
Referring to Fig. 7 H, when the son in create (or configuration) subpath for auxiliary interactive is play, create son that (or configuration) only be complementary with the segment section of whole playlist section individually and play.More specifically, in the situation of Fig. 7 F, create to have and play with whole section that plays (that is, playlist present (or playback) section) entry time of coupling and the single son of time departure.Yet, in Fig. 7 H, create to have and play corresponding to the son of the entry time of a segment section in whole section that plays (that is, playlist present (or playback) section) and time departure.Therefore, clearly among Fig. 7 G the notion of applied " time slot " also can similarly be applied to Fig. 7 H.
In other words, replace a part of reproducing the whole master data section of presenting of (or presenting) by playlist with subdata.For example, reproduced main interactive graphic stream by whole section the part that composite is reproduced, and this another part of whole section has reproduced auxiliary interactive.Therefore, because do not require that a reproduction section (or the section of presenting) that son in the subpath plays is identical with broadcast item in the main path, so sub-broadcast Xiang Nenggeng uses auxiliary interactive diversifiedly.Yet, in this case, form the border between the reproduction (or presenting) of the reproduction (or presenting) of main montage and sub-montage.Here, at the reproduction period of main montage, main montage becomes the reproduction of sub-montage.In this, even need being supported to make, system also can between audio stream, carry out seamless presenting at boundary.
As mentioned above, Fig. 7 A to 7H illustrates the example of creating single subpath.Clearly when creating a plurality of subpath, can use the method described in Fig. 6 A to 6C.More specifically, when " main interactive graphics (IG) " when not existing with the multiplexed independent stream of main AV stream, preferably any in the method described in the application drawing 6A to 6E.Perhaps, when " main interactive graphics (IG) " and main AV flow when multiplexed, preferably any in the method described in the application drawing 7A to 7H.On the other hand, when " auxiliary interactive graphic " do not flow when synchronous with main AV, preferably any in the method described in the application drawing 6A to 6E.On the contrary, when " auxiliary interactive graphic " and main AV flow when synchronous, preferably any in the method described in the application drawing 7A to 7H.
