Fig. 7 illustrates a kind of use constitutes the method for virtual package based on the Virtual File System according to file structure of the present invention concept map.
Referring to Fig. 7, specific file structure (that is the Pan Bao of Fig. 2) is recorded in the dish that is loaded.Comprise that Fig. 6 B is included in the local storage to the local memory file system 41 of one of Pan Bao of 6G.
Local memory file system 41 comprises and the dish that is loaded (for example, binding unit and the binding information that Disc_id#1) makes up.
With above explanation explicitly, the present invention exemplarily illustrates following situation, wherein according to the preferred embodiment of Fig. 6 D, the dish of local memory file system 41 wraps in the organization id catalogue and comprises the dish ID catalogue 63 and the second share directory 63a for 62 times.
As seen from Fig. 7, each of the dish ID catalogue 63 and the second share directory 63a include with the binding unit of dish (for example, OrgID 1 and the DiscID_1) combination that is loaded 2..
Local memory file system 41 comprises that binding information 3..3. binding information comprises the various information that 2. are associated with the binding unit, for example, and the update times of the file type of binding unit, binding unit, binding method or the like.But, binding method that can be predetermined as required to some example application.In other words, even without binding information, this predetermined binding method also can be applied to some example.
With above explanation explicitly, the binding unit 2. be similar to Pan Bao substantially.Particularly, the binding unit can comprise with dish in the specific playlist file that comprised have the play list file of same names, thereby itself and specific playlist file can be made up.2. and the difference of Pan Bao between 1. but the binding unit alone can not be as reproductions/management document, and this fact is considered to be and binds the unit.
Should be noted that binding the unit 2. itself can not operate as reproduction/management document, these are 1. different with Pan Bao.2. be designed to carry out alone data reproduction if suppose the binding unit, then this data reproduction is similar to the data reproduction of local storage, thereby the raw data that the aforesaid operations of binding unit and reproduction simultaneously of the present invention are recorded in the dish is opposing with the purpose that is recorded in the additional data in the local storage.
Therefore, Virtual File System (VFS) carry out to use above-mentioned binding information 3. will bind the bindings that 1. 2. the unit make up with the Pan Bao of the dish that is loaded, thereby constitutes new virtual package 51.
With above explanation explicitly, below the various features of the virtual package that will constitute to above-mentioned bindings and by this bindings describe.
First feature of bindings is as follows.The title of the file that is comprised in 1. as the fruit tray bag equals to bind the title of the file that the unit comprised in 2., then replaces the file that is comprised in the virtual package 51 with the above-mentioned file of binding unit in 2. that be included in.For example, as shown in Figure 7, the binding unit exists in 2. and is included in index file (index.bdmv) 81 and play list file (00000.mpls) 71 index file (index.bdmv) 82 and the play list file (00000.mpls) 72 with same file name of Pan Bao in 1., then replaces this index file (index.bdmv) 82 and play list file (00000.mpls) 72 with the file of the binding unit that is included in new virtual package in 2..
Can provide the exterior content supplier (CP) of index file (index.bdmv) 82 that aforementioned binding unit comprised in 2. and play list file (00000.mpls) 72 must consider index file (index.bdmv) 81 and play list file (00000.mpls) 71 that above-mentioned index file (index.bdmv) 82 and play list file (00000.mpls) 72 replace Pan Bao to be comprised in 1., and must be to finish file (promptly, complete file) form is made above-mentioned file in advance, thereby outside CP can provide index file (index.bdmv) 82 that is shaped fully and the play list file (00000.bdmv) 72 that is shaped fully in advance.
But, externally CP does not provide under the situation of index file (index.bdmv) 82 that is shaped fully and the play list file (00000.bdmv) 72 that is shaped fully, virtual package 51 must be carried out combination operation explicitly with being included in index file (index.bdmv) 81 and the play list file (00000.mpls) 71 of Pan Bao in 1., thereby can use aforementioned combination operation to constitute new index file (index.bdmv) (not shown) and new play list file (00000.mpls) (not shown).
Second feature of bindings is as follows.The title of the file that the title of the file that is comprised in 1. as the fruit tray bag and binding unit are comprised in 2. is different, then binds file that the unit comprised in 2. by additional or add virtual package to.For example, as shown in Figure 7, the file of the filename that the filename that " 01000.mpls " file that is comprised among " 02000.clpi " file that is comprised in the disc ID_1 catalogue 63 and " 02000.m2ts " file and the second share directory 63a, " 03000.clpi " file and the indication of " 03000.m2ts " file be new having of adding and Pan Bao are comprised in 1. is different, thus new virtual package 51 disposed by adding above-mentioned file.
The 3rd feature of bindings is as follows.If there is identical filename in the binding unit in disc ID_1 catalogue 63 and the second share directory 63a in 2., then at first use the file that is comprised in the disc ID_1 catalogue 63.In other words, the priority ranking of the file that is constituted in the virtual package 51 is defined as disc ID_1 catalogue 63 → the second share directory 63a → Pan Bao order 1..
Therefore, suppose to have " 00002.mpls " file (not shown) in the disc ID_1 catalogue 63 and the second share directory 63a, then the file that is comprised in this new virtual package will be replaced with " 00002.mpls " file in the aforementioned disc of the being included in ID_1 catalogue 63.In this way, suppose in the second share directory 63a, to exist " 00003.mpls " file (not shown), then will replace the file that is included in the new virtual package 51 with " 00003.mpls " file that is included in the disc ID_1 catalogue 63.Therefore, virtual package 51 is made of above-mentioned first to the 3rd feature, thus the raw data that can use aforementioned virtual package 51 to reproduce simultaneously to be recorded in the dish and be recorded in additional data in the local storage 15.
Fig. 8 a is the concept nature file structure of using in local memory file system according to other preferred embodiment of the present invention to 8c.
Fig. 8 a illustrates the detailed structure of dish ID catalogue 631,632 and 633.Particularly, as seen, coil the application directory 6311 that is comprised in ID catalogue 631,632 and 633 and separate with 6312 and virtual package data directory 6313 with application directory 6311 with 6312 from Fig. 8.For example, disc ID_0 catalogue 631, disc ID_1 catalogue 632 and disc ID_2 catalogue 633 are arranged on org ID_0 catalogue 621 times.Disc ID_0 catalogue 631 comprises application directory 6311 and 6312 and virtual package data directory 6313.In this case, application directory 6311 and 6312 each only comprise application file or program by dish control with specific ID " disc ID_0 ".Virtual package data directory 6313 makes up with the particular plate of " disc ID_0 ", and comprises the file that will be included in the virtual package.
Fig. 8 B illustrates the detailed structure of virtual package data directory 6313 to 8C.With above explanation explicitly, Fig. 8 B is characterised in that to the preferred embodiment of 8C, uses Active Directory (Active) and non-Active Directory (Inactive) at Fig. 8 B in 8C.
In this case, movable (Active) catalogue is meant the catalogue of being made up of the file of current virtual package, and the All Files that is comprised in indicative of active (Inactive) catalogue is used for bindings.
Preferably, movable (Active) catalogue can be only by a Java system (for example, BD-J uses) control, and the file that is comprised in movable (Active) catalogue can only just reproduce after visit, and can not allow such as editing operations such as file deletes.
Non-activity (Inactive) is meant the catalogue of being made up of one or more files that can not constitute current virtual package.Therefore, non-activity (Inactive) catalogue is by Java system (for example, BD-J uses) control, and the file that is comprised in non-activity (Inactive) catalogue is accessed, allows such as editing operations such as file deletes thus.
With above explanation explicitly, single virtual bag data directory 6313 can comprise single-unit activity (Active) catalogue 6313a and a plurality of non-Active Directory 6313b and 6313c.In other words, the single-unit activity catalogue must be rendered as the catalogue that is used for current bindings in the virtual package data directory.And, as required, also can present at least one non-Active Directory as the catalogue that is not used in current bindings in the virtual package data directory.And non-activity (Inactive) catalogue can be by the activity of changing to (Active) catalogue, and movable (Active) catalogue also can be changed to non-activity (Inactive) catalogue.
But,, in the virtual package data directory, can present a plurality of activities (Active) catalogue as another example.In this case, may need to be used to control the high-rise control program of bindings.
The catalogue that is comprised in the virtual package data directory 6313 (00000,00001 and 00002) can be used as the catalogue that can store according to the file of institute's download content data classification.In other words, as required, a plurality of content data unit that comprised in the single title can be able to be separated from each other.For example, single title comprises an audio stream and a graphical stream.This audio stream is stored in the non-Active Directory (00001), and this graphical stream is stored in the non-Active Directory (00002).
Therefore, before bindings, the content-data of separation/storage moves on to activity (Active) catalogue.
Fig. 8 B illustrates the example that comprises single-unit activity catalogue (00000) and a plurality of non-Active Directory (00001,00002) in the virtual package data directory 6313.In Active Directory (00000), present the binding unit that is used to constitute virtual package.Although the file that comprises in the non-Active Directory (00001,00002) has been shown among Fig. 8 B, can in the structure of Fig. 8 B, present the All Files that is comprised in the binding unit of Active Directory (00000).
Fig. 8 C illustrates another example that can constitute the binding unit of virtual package in the Active Directory (0000).In other words, a plurality of content data unit that comprised in the single title are configured in this group appended document.For example, first group of (101S) audio file (00000.01.mpls, 01000.clpi, and 01000.m2ts), second group (102S) presents figure (PG) file (00000.02.mpls, 09001.clpi and 09001.m2ts) and the 3rd group of (103S) text subtitle (TXT-ST) file (00000.03.mpls, 09002.clpi and 09002.m2ts) can be disposed with being separated from each other.In the situation of above-mentioned example, the first file group 101S, the second file group 102S and the 3rd file group 103S download when classifying according to content element, in non-Active Directory, and before bindings, move on to Active Directory as single file storage, thereby constituted single binding unit.
Fig. 9 A is the concept map that illustrates according to the method for another virtual package of formation of the present invention to 9C.For example, Fig. 9 A has illustrated the binding method that uses in the binding unit of Fig. 8 C in 9C.
The a plurality of play list file 101,102 that comprised in single play list file (00000.mpls) 100 that Fig. 9 A is comprised in illustrating and will coiling and the binding unit and the bindings of 103 combinations.It may be noted that a plurality of play list file 101,102 and 103 that binding is comprised in the unit equal with coil in the play list file of each content of being associated of the play list file 100 that comprised.
Fig. 9 B illustrates the detailed bindings of the processing shown in Fig. 9 B.
With above explanation explicitly, the play list file 100 that Fig. 9 B illustrates dish constitutes the example that a plurality of play list file 101,102 and 103 that comprised in main paths and the binding unit constitute subpath respectively.
At first, the a plurality of play list file 101,102 that comprised in the binding unit and 103 are merged to constitute at least one single sub path, then the play list file 100 that is comprised in this subpath and the dish is made up, thereby constitute the virtual playlist file that is comprised in the virtual package.In this case, can constitute single subpath, or also can constitute a plurality of subpaths according to each play list file 101,102 and 103 classification.
With above explanation explicitly, Fig. 9 C illustrates play list file 100 that Pan Zhongsuo comprises and constitutes each play list file 101,102 and 103 that is comprised in main paths and the binding unit and comprise main path and subpath.
In this case, by merge the play list file 101,102 that comprised in the binding unit and 103 and not with dish in the play list file 100 that comprised merge the virtual playlist file 104 that constitutes in the virtual package to be comprised.Fig. 9 C illustrates the example that each play list file 101,102 and 103 that binding comprised in the unit comprises main path, comprises the content-data of the play list file that Pan Zhongsuo comprises thus in Fig. 9 C in advance.
With above explanation explicitly, suppose only to present single play list file 101,102 or 103 in the unit in binding, then corresponding play list file available virtual play list file 104 is replaced.
Figure 10 A is the concept nature file structure of using in local memory file system of the preferred embodiment other according to the present invention to 10D.Particularly, Figure 10 A is to describe on the basis of share directory to the structure of 10D.
Among Figure 10 A with the preferred embodiment of Fig. 6 D in identical mode described and be used to allow organization id catalogue 621,622 and 623 to share the first share directory 62a of general file information and be used for permission dish ID catalogue 631,632 and the 633 second share directory 63a that share the general file information.
And each catalogue is managed by the resident applications as system program.In other words, the file of the particular category that is comprised in the local storage of the resident applications editor who is comprised in the optical recording/reproducing apparatus, or the bindings of the file of control particular category.
With above explanation explicitly, according to the preferred embodiment of Figure 10 A, the binding unit of the first share directory 62a, dish ID catalogue 631 to 633 and the second share directory 63a is configured to have same format.
With above explanation explicitly, below will the file that be comprised among the file that be comprised among the first share directory 62a and the second share directory 63a be described.
At first, should be noted that the number of the type of institute's include file among the first share directory 62a is limited, because in the organization id catalogue 621 to 623 that different content supplier (CP) is constituted infringement of copyright may take place.Therefore, preferably the first share directory 62a is made up of the minimum file that does not have the infringement of copyright problem.
The file type that is comprised among the second share directory 63a has variety of way to use, and is lower because the dish ID catalogue that is made of single CP 631 to 633 produces the probability of above-mentioned infringement of copyright problem.For example, can provide general click sound file, perhaps as required, also can provide new movie trailer title as auxiliary data as auxiliary data.But, should be noted that not comprise database file or the content file that is associated with particular plate among the second share directory 63a.Preferably, the priority ranking of the bindings of above-mentioned binding unit can be defined as coiling the order of ID catalogue 63 → the second share directory 63a → first share directory 62a.
Figure 10 B exemplarily illustrates the header syntax of the second share directory 63a.In other words, the preferred embodiment of Figure 10 B is designed to consider with the title to be that unit comes editing files.
Therefore, suppose that the specific title (for example, title #1) that is comprised among the second share directory 63a only is associated with particular plate ID catalogue 631, and be not associated with other dish ID catalogue 632 and 633, can independent execute file editor.
But,, then be difficult to carry out aforesaid unique file editor if the specific title that is comprised among the second share directory 63a (for example, title #2) is associated with a plurality of dish ID catalogues 631 and 632.In this case, must edit all dish ID catalogues 631 and 632 that are associated with corresponding title simultaneously.
As another example, can design a kind of system that when making optical recording/reproducing apparatus, prevents the file editor.And, also can design the another kind of system that file is deleted that when execute file adds, prevents.In this way, can be according to its uniqueness should be used for designing various systems.
Figure 10 C illustrates the various preferred embodiments that are included in the file structure in the local memory file system according to of the present invention to 10D.Particularly, Figure 10 C has illustrated the file structure that is used for making up in the binding unit binding information in 10D.
Binding information is meant the customizing messages that can determine bindings.Figure 10 C is characterised in that to the preferred embodiment of 10D it comprises additional catalogue and the appended document structure that is used for binding information.
For example, the binding unit comprises metadata catalog (META), and metadata catalog (META) comprises the file that is equipped with binding information.
According to the preferred embodiment of Figure 10 C to 10D, the above-mentioned file that is equipped with binding information is called inventory file, and, can be described as one of " bumf_disc0_ID.xml " file 201, " bumf_dshared.xml " file 202 and " bumf_oshared.xml " file 203 etc. according to upper binding unit classification.It will be apparent for a person skilled in the art that metadata catalog (META) also can comprise other various meta data files as required except that above-mentioned inventory file.
Above-mentioned inventory file comprises various binding informations unit.
In other words, inventory file can be specified the bound object file, and can determine the content-data of bindings as required.And inventory file can write down the download time and the update time of specific file, can comprise that also this specific file of indication is whether corresponding to the customizing messages of a file edit object.
With above explanation explicitly, Figure 10 C is illustrated in an example that constitutes single inventory file in each dish, and Figure 10 D is illustrated in another example that constitutes inventory file in each title that Pan Zhongsuo comprises.
For example, three titles that comprised in the binding unit of dish ID catalogue 631 can have " bumf_disc0_ID_001.xml " file 201, " bumf_disc0_ID_002.xml " file 202 and " bumf_disc0_ID_003.xml " file 203 respectively.In this way, each title of the second share directory 63a also can have " bumf_dshared_001.xml " file 301, " bumf_dshared_002.xml " file 302 and " bumf_dshared_003.xml " file 303 respectively.When making up the inventory file of each title as described above, can carry out the binding and the editing operation of each title more efficiently.
It will be apparent for a person skilled in the art that and to carry out various modifications and changes in the present invention and can not depart from the spirit and scope of the present invention.Thus, the present invention is intended to cover these modifications and changes of the present invention, as long as they drop within claims and the equivalence techniques scheme scope thereof.
