The stream catalogue comprises audio/video (AV) stream (being referred to as " AV stream " afterwards) file.More particularly, AV stream (01000.m2ts, 02000.m2ts) generally can be the form of MPEG2 transmission grouping, and is named as " * .m2ts ".In the BD standard, AV stream is called as clip files, and in explanation of the present invention, " master data " and " subdata " will constitute the AV stream file.In addition, clip information directory (CLIPINF) comprise with stream catalogue in the contained corresponding one by one clip information file (01000.clpi, 02000.clpi) of AV stream file (clip files).
Clip information file (* .clpi) comprises the attribute information and the timing information of corresponding AV stream.More particularly, timing information comprises the map information that uses the entrance mapping to present time stamp (PTS) with source packet number (SPN) mapping.In the BD standard, each of corresponding one by one each other AV stream (* .m2ts) and corresponding clip information file (* .clpi) composition is to being called as a montage.For example, be included in attribute and timing information that 01000.clpi among the CLIPINF comprises 01000.m2ts contained among the STREAM, and 01000.clpi and 01000.m2ts constitute a montage (Clip).In the present invention, " main montage " refers to the montage that is associated with master data, and " sub-montage " refers to the montage that is associated with subdata.
Return to consult Fig. 2 A, playlist directory (PLAYLIST) comprises one or more play list file (* .mpls), and wherein each play list file (* .mpls) comprises at least one the broadcast item between the broadcast area of specifying specific clips.More particularly, play item and comprise the information that presents starting and ending time (In-Time and Out-time) of specifying specific clips, this specific clips can be specified by the clip_Information_File_name that plays in the item.Correspondingly, the reproduction management control documents of (or playback) required montage is reproduced in play list file (* .mpls) representative from one or more combinations of playing item.
Correspondingly, Fig. 2 B illustrates the relation (or related) between play list file and the main montage.More particularly, play list file comprises having the main path that at least one plays item, and each broadcast item comprises reproduction (or playback) management information that is used for reproducing (or playback) specific main montage (montage # 1, montage # 2, montage # 3).Therefore, when reproducing the playlist of (or playback) Fig. 2 B, the AV stream # 1 in the main montage # 1 reproduces by playing a #1.Then, the AV stream # 2 in the main montage # 2 reproduces by playing a #2 subsequently, and the stream of the AV in main montage # 3 #3 reproduces by playing a #3.
Fig. 3 illustrates the general structure according to information (or data) of the present invention, that be associated with file structure on being recorded in CD.More particularly, from the inner ring (or center) of dish, coil and comprise: occupy the file system information area of coiling inner round portion, occupy the AV stream of coiling the outmost turns part and distinguish and occupy database community between file system information area and the flow data district.In file system information area, record the system information that is used to control whole data file.In addition, the master data such as audio/video/graphic data is recorded in the AV stream district.Generic-document, play list file and clip information file are recorded in the database community of coiling.More particularly, such as mentioned above, the data that are recorded in the AV stream district in the dish are called as master data.Therefore, by using the information in the database community, the user can select him to want the AV stream that reproduces, and determines and use the suitable reproducting method of selected AV stream.
The present invention relates to be used for the method that (or playback) writes down is reproduced in the subdata combination that is recorded in the master data of CD and be present in the external source.Hereinafter, will describe each example of the present invention in conjunction with the accompanying drawings.Fig. 4 illustrates according to optical recording of the present invention and/or transcriber 10.Optical recording and/or transcriber 10 comprise substantially: pickup unit 11 is used for reproducing the control information that comprises master data and is recorded in fileinfo on the CD; Servo 14, be used for controlling the operation of pickup unit 11; Signal processor 13, the playback signal that is used for being received from pickup unit 11 reverts to the signal value that closes need, but perhaps the signal that will write down is modulated into the CD tracer signal and transmits the signal of being modulated; And microcomputer 16, be used for controlling aforesaid operations.
In addition, controller 12 is downloaded the subdata that is present in the external source according to user command, and the subdata of being downloaded is stored in the local storage 15.Controller 12 is created new composite subsequently, is recorded in the master data in the CD and is stored in local subdata of storing in 15 in order to reproduction.After this, according to user command, controller 12 reproduces master data and subdata by using composite.AV demoder 17 is carried out the final decoding of output data (being master data and/or subdata) according to the control of controller 17, and will offer the user through the data of decoding.In addition, for signal record in CD, AV scrambler 18 is converted to input signal specific format signal (for example MPEG2 transport stream) and the signal through conversion will be offered signal processor 13 according to the control of controller 12.
This locality storage 15 of storage subdata also can be configured to for example hard disk drive (HDD).In addition, the composite of new establishment maybe can be stored in the local storage 15 and also use for using future, maybe can being temporary in the independent dynamic storage.As an example of the present invention, optical recording and/or transcriber are created new composite separately.In another example, when the carrier data were also stored the subdata of being downloaded instantly, composite also can be downloaded and store.In this case, do not require optical recording and/or transcriber 10 another independent composite of establishment.
In addition, if the user wants subdata and composite are stored in local storage 15 for using in the future, it is preferable then giving the playlist higher priority of only managing master data of service recorder in CD.Below in conjunction with Fig. 6 A to Fig. 7 D the method for creating composite is elaborated.
In the middle of the structure according to optical recording of the present invention and/or transcriber 10 shown in Figure 4, Fig. 5 A and Fig. 5 B illustrate device and the method for reproducing data of reproducing data respectively.More particularly, be the CD of #1 when having loaded disc identifier (disc_id)---be disc_id=#1) time, the controller 12 of optical recording and/or transcriber 10 is verified the sign of respective disc by using pickup unit 11 and signal processor 13.Then, controller 12 verifies whether the one group of subdata that is associated with " disc_id=#1 " is present in the subdata central (S10) of being stored in the local storage 15.
For example, if local 15 interior first auxiliary audio stream (AuxAudiol), second auxiliary audio stream (Aux Audio2) and the auxiliary graphical stream (Aux PG) that present that exist at " disc_id=#1 " of storing, then controller 12 is provided with selection reproduction (or playback) stream (S20) according to user's request or system.In other words, controller 12 can notify user's subdata to exist, and controller 12 only reproduces the composite that the master data that is recorded in the dish or selection and reproduction comprise the subdata in the local storage according to user command or system's setting subsequently.Therefore, when the user wishes to be recorded in the master data in the CD and is stored in the subdata combination in the local storage 15 and when reproducing, controller 12 is created such as the reproduction of reproduction management documents such as composite playlist file with the management data splitting, and uses the new reproduction management document reproduction data of creating (S202).
Correspondingly, the new composite playlist file of creating is stored in the local storage 15, and when this subdata of later reproduction, it can be used again.Fig. 5 A illustrates and is stored in the local storage 15 to reproduce as an example at the composite playlist file of the text subtitle stream of the subdata of " disc_id=#2 ".Therefore, when dish ID is loaded in optical recording and/or the transcriber 10 for the CD of " disc_id=#2 ", use the composite that has been stored in the local storage 15, and can carry out data reproduction immediately and needn't create new composite.In addition, as mentioned above, composite also can be downloaded and use.All preferred embodiments of the inner structure of reproduction management document according to the present invention are elaborated to Fig. 9 D below in conjunction with Fig. 6 A.
To describe the common trait that is used for all embodiment of configuration reproduction management document (for example playlist) according to the present invention below.Be used for the fileinfo that master data and subdata are reproduced with array mode is comprised in play list file.Here, master data is play a reproduction by included at least one in the main path in the play list file.In addition, subdata is play a reproduction by son included in the subpath in the play list file.In addition, in the subpath included son at subdata play or with main path in included each play and be associated (as Fig. 6 A to as shown in the 6E), perhaps with main path in whole playlist reproduce (or playback) part correlation connection (as Fig. 9 A to as shown in Fig. 9 C).
In addition, auxiliary audio stream (AUX audio frequency) or auxiliary figure (PG) stream that presents are suitable for use as subdata among the present invention.More particularly, the auxiliary flow in the language configuration subdata that the main flow that comprises in available and the master data is different.Perhaps, promptly use the language configuration subdata identical, also subdata can be configured to have different attributes with main flow.This generic attribute can comprise that channel number difference, type of coding are not equal.In addition, promptly use the language identical to dispose auxiliary flow, also the content configuration of auxiliary flow can be become multi-form with the language of included main flow in the master data.Therefore, in explanation of the present invention, will be with auxiliary audio stream and the auxiliary example of graphical stream that present as subdata.
At last, when disposing composite, should will be stored in for information about in the local storage 15 according to the present invention.More particularly, prepare in advance and be downloaded by the author of coiling for information about with subdata.Correspondingly, as shown in Fig. 5 A, " information " that is stored in the local storage 15 represents the information that is used for disposing composite.
Fig. 6 A illustrates the embodiment of the son broadcast item in the composite that the method that disposes composite is central with each broadcast item is associated to 7D to 6E and Fig. 7 A.Therefore, Fig. 6 A illustrates the example of playing item according to configuration in the middle of the method for configuration composite of the present invention to 6E.Consult Fig. 6 A, when the son of configuration in the subpath play, by with main path in each play a corresponding one by one son broadcast item that mate by separate configurations.
More particularly, by specify with playlist in all are play a simultaneously corresponding son and play, available be included in the sub-montage and replace by auxiliary audio stream that each corresponding son is play an appointment be included in the main montage and by the main audio stream of each broadcast item appointment.This has simplified system and has been beneficial to the management that each plays item.Therefore, when using the combinations thereof playlist to reproduce CD, coil interior main video flowing playback video signal from being recorded in, and the auxiliary audio stream reproducing audio signal from be recorded in local storage 15.In other words, being recorded in the auxiliary audio stream that the main audio stream in the CD is stored in the local storage 15 substitutes.
Consult Fig. 6 B, when the son in disposing subpath is play item, play item by separate configurations with each broadcast son that mates accordingly one by one in the main path.Yet the not every item of playing all exists the son of coupling to play item.In other words, by specify with playlist in a specific corresponding son of playing play, only be included in the main montage and can be included in the sub-montage and be substituted by the auxiliary audio stream of corresponding son broadcast item appointment by the specific main audio stream of playing an appointment.
Therefore, when using the combinations thereof playlist to reproduce CD, vision signal is reproduced from the main video flowing that is recorded in the dish.And, when existing son to play item according to subpath, the auxiliary video stream reproducing audio signal from be recorded in local storage 15.Yet, when group broadcast item does not exist, from be included in main path and by the main audio stream of playing an appointment, reproduce CD.In other words, the part of the main audio stream in the CD is replaced by the auxiliary audio stream that is stored in the local storage 15.
Consult Fig. 6 C, when the son of configuration in the subpath play, play with the son of corresponding relation coupling one by one with in the main path each and to play by separate configurations.Yet, play item for one and can exist the son of a plurality of couplings to play item.In other words, in Fig. 6 A and Fig. 6 B, play a son that has a coupling for each and play item.In Fig. 6 C, play item for one and exist the son of a plurality of couplings to play item on the contrary.Here, Fig. 6 C only illustrates one and plays an example of (playing a #1).Yet this aspect clearly of the present invention also can be applicable to other broadcast (play a #2, play an item #3) with being equal to.
More particularly, by specify with playlist in a specific corresponding a plurality of son of playing play, available be included in a plurality of sub-montages and replace by the auxiliary audio streams that corresponding a plurality of sons are play an appointment be included in the main montage and by the main audio stream of broadcast item appointment.For example, can replace by the auxiliary audio signal that has different attribute (for example language) with two of every parts reproducing by playing an audio signal of #1 reproduction.Therefore, when using combinations thereof playlist reproduction CD, vision signal is that the main video flowing from be recorded in CD reproduces, and when playing item according to subpath existence, then from being recorded in the local auxiliary audio stream reproducing audio signal of storing 15.Yet, when group broadcast item does not exist, from be included in main montage and by the main audio stream reproducing audio signal of playing an appointment.
Consult Fig. 6 D, when the son in disposing subpath is play item, play item by separate configurations with each broadcast son that mates in the main path.Yet, can be only at son broadcast item by the local part existence in the middle of the entire portion of broadcast item reproduction and this broadcast coupling.More particularly, in Fig. 6 A, 6B and 6C, one or more sons are play Xiang Yuyi complete broadcast item parts coupling.Yet, in Fig. 6 D, only in a local part, exist with one and play a corresponding son broadcast item.In other words, by only during the part of part, specify be included in playlist in a specific corresponding son of playing play, comprise by a corresponding entire portion of reproducing of playing: be included in the main montage and by the main audio stream of this broadcasts item appointment and be included in the sub-montage and by the auxiliary audio stream of son broadcast item appointment.For example, only reproduced by audio signal and auxiliary audio signal in the part of playing in the entire portion of #1 reproduction with different attribute (for example, language).
Therefore, when using the combinations thereof playlist to reproduce CD, from being recorded in the main video flowing playback video signal in the dish, and from be recorded in local storage 15 and by the auxiliary audio stream that the son in the subpath is play an appointment, reproduce a whole part (or local part) that presents part of playing a sound signal of reproducing by specific.In this case, the broadcast item interior owing to reproducing part (or presenting part) that does not require the son broadcast item in the subpath and main path is identical, so the sub item of playing can be used auxiliary audio stream in more various mode.Yet, in this case, can produce 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 subsequently becomes the reproduction of sub-montage.At this moment, even need being supported, system also can between all audio streams, realize seamless presenting at boundary.
Consult Fig. 6 E, when the son in disposing subpath is play item, play item by separate configurations with each broadcast son that mates in the main path.Yet each son is play item by its corresponding broadcast of a diverse ways coupling.More particularly, in Fig. 6 E, can be applicable to each as Fig. 6 A to the example that disposes son broadcast item as shown in the 6D and play item.For example, play a method (shown in Fig. 6 A or 6B) of replacing the entire portion of playing a #1, play a method (shown in Fig. 6 C) of replacing the entire portion of playing a #2 and play an only a part of method of replacing in the entire portion of playing item # 3 with a plurality of sons and in Fig. 6 E, all be employed with a son with a son.Therefore, obviously each is play Xiang Eryan, can reproduce (or presenting) composite according to all methods shown in Fig. 6 A to Fig. 6 D.
Fig. 7 A illustrates the example that reproduces the configuration subpath in the middle of the method for management document according to configuration of the present invention to 7D.Therefore, the method play of the son of configuration in the subpath applicable to Fig. 6 A in any one example shown in the 6E.Yet, being used to dispose the new method that son is play item shown in the situation of Fig. 7 D, this will be elaborated in the back.
Consult Fig. 7 A, for subdata configuration subpath the time, for each auxiliary data flow disposes a single sub path.For example, configurable subpath is so that subpath # 1 designates auxiliary audio stream # 1, subpath # 2 designates auxiliary audio stream # 2, and subpath # 3 specifies the auxiliary graphical stream that presents.Therefore, when reproducing the combinations thereof playlist, one of the subpath # 1 of the identical auxiliary flow file of designated store in this locality storage 15 and subpath # 2 are selected and reproduce with being recorded in the dish and by the master data of main path appointment.Here, the auxiliary subpath # 3 that presents graphical stream of appointment also can be reproduced.
