In case receive the control signal of self-controller 12, demoder 17 is output data (being raw data and/or additional data) decoding the most at last just, and decoded results is offered the user.
In case receive the control signal of self-controller 12, scrambler 18 just converts input signal to the signal (for example MPEG2 transport stream) of specific format, and the result that will change is sent to signal processor 13.
New virtual package can be stored in the local storage 15 so that it can be in repeated use in the future.In addition, new virtual package also can be temporary in the additional dynamic storage and subsequently and can be used.
Fig. 4 b illustrates a kind of use according to the present invention to be included in the block scheme that the device that reproduces optical disc data is stored in this locality in the middle of all parts in the optical recording/reproducing apparatus 10.
To the information that be stored in the local storage 15 be described below.Local storage 15 storages according to the present invention comprise the catalogue of each disc identifier (ID) information and the fileinfo of file (the catalogue file tree information of Disc_id #n) and a plurality of additional clip of downloading from the outside.Local storage 15 also can be stored used binding information of the bindings that is associated with Pan Bao and a plurality of files (content identification message file) that are used for explaining the content-data that is stored in local storage 15.
Particularly, local storage 15 can comprise that a plurality of file information units (the catalogue file tree information of Disc_id #n) are to deal with different dishes.Therefore, local storage 15 needs a file system that is used to manage above-mentioned file information units in addition.Particularly, this document system is also referred to as local memory file system 41, and local memory file system 41 is meant and is used for the system of managed storage at the All Files of this locality storage 15.
Therefore, if the CD of particular plate ID (Disc_id) is loaded in the optical recording/reproducing apparatus 10, the controller 12 that then is included in the optical recording/reproducing apparatus 10 uses pickup unit 11 and signal processor 13 to discern the id information of dish, read the fileinfo that equates with the disc id information that is loaded in the middle of the All Files message unit from be stored in local storage 15, constitute virtual package by the information and the Pan Bao binding (or combination) of will be read, and use the virtual package that is constituted to reproduce the raw data of dish and the additional data of local storage.
Hereinafter will describe the preferred embodiment that is used to generate virtual package according to the present invention.
Fig. 5 is according to a kind of concept map that is used to constitute the method for above-mentioned virtual package of the present invention.
Be stored under the local situation of storing in 15 in information shown in Fig. 4 b and content, if particular plate is loaded in the optical recording/reproducing apparatus 10, then optical recording/reproducing apparatus 10 reads the filesystem information 41 that is included in the local storage 15, and read the dish filesystem information 42 that comprises the file structure that is recorded in the dish simultaneously, thereby create out VFS.More particularly, Virtual File System (VFS) is meant and constitutes the file system that is contained in another file system of the local dish of storing the file system in 15 and being loaded with supervisory packet virtually.
Optical recording/reproducing apparatus uses Virtual File System above-mentioned (VFS) to constitute new virtual package to reproduce raw data that is recorded in the dish and the additional data that is recorded in the local storage simultaneously.For this reason, optical recording/reproducing apparatus 10 reads and coils the fileinfo that (for example Disc_id #1) be associated (the catalogue file tree information of Disc_id #n) from file system, and carries out bindings and close with the dish package of fileinfo that will be read and the dish (Disc_id #1) that is loaded or the fileinfo that is read is added to Pan Bao.
The virtual package that is made of above-mentioned bindings is meant the file structure that is used to reproduce/manage original clip 422 and additional clip 412.Original clip 422 is made of the raw data that is recorded in the dish.Additional clip 412 is made of the additional data that is recorded in the local storage.
Fig. 6 a illustrates a kind of use according to the present invention constitutes the method for virtual package based on the Virtual File System (VFS) of file structure concept map.
Consult Fig. 6 a, specific Pan Bao (for example structure of Fig. 2) is recorded in the dish that is loaded.Local memory file system 41 is included in the local storage.Local memory file system 41 comprises binding unit and the binding information with dish (for example Disc_id #1) combination that is loaded.
With above-mentioned explanation explicitly, the binding unit wraps similar with dish.Specifically, the binding unit can comprise and be included in the play list file that specific playlist file in the dish has same names so that its can with this specific playlist file combination.Yet, should be noted that binding unit itself can not be as the work of reproduction/management document, these are different with the dish bag.If suppose that the binding unit is designed to itself and can carries out data reproduction, then this data reproduction is similar to the data reproduction of local storage, and is opposing with the purpose that is recorded in the additional data in the local storage thereby the aforesaid operations of binding unit and the present invention reproduce the raw data that is recorded in the dish simultaneously.
Binding information comprises a plurality of message units that are associated with the binding unit, for example binds the file type of unit, the update times of binding the unit and binding method etc.
Therefore, Virtual File System (VFS) is carried out bindings so that will bind the unit and the dish package of the dish that loaded closes with above-mentioned binding information, thereby constitutes new virtual package.
For example, if the binding unit that is associated with the dish that is loaded (for example Disc_id #1) comprises first play list file (00000.mpls), by the montage of first play list file (00000.mpls) management (promptly, clip information file " 02000.clpi ") and stream file (02000.m2ts), then be included in first play list file (00000.mpls) and second play list file (00000.mpls) combination that is included in the dish bag in the binding unit, thereby create out the virtual package that comprises new played file (00000.mpls).In this case, second play list file (00000.mpls) has identical filename with first play list file (00000.mpls).
For ease of explanation, it should be noted that, the play list file 61 that is included in the dish bag is called as original playlist file 62 (original playlist), the play list file 62 that is included in the binding unit is called as additional list file (additional playlist), and by original playlist file 61 and the play list file 63 that 62 combinations of additional playlist file constitute are called as virtual playlist file 63 (virtual playlist).
Clip information file the virtual playlist file 63 in virtual package (* .clpi) and stream file (* .m2ts) are included in the virtual package, only to realize their unified management.Each content of clip information file (* .clpi) and stream file (* .m2ts) does not change because of bindings.More particularly, clip information file (01000.clpi) in the dish bag and stream file (01000.m2ts) only are and bind clip information file (02000.clpi) and stream file (02000.m2ts) combination in the unit and do not do any change that Zu He result is comprised in the virtual package thus.
With top explanation explicitly, index file (index) and obj ect file (MovieObject) (not shown) be as topmost paper, and can upgrade from conventional index file (index) and conventional obj ect file (MovieObject) based on virtual playlist file 63.When virtual playlist file 63 changed this title into another title again, above-mentioned renewal operation took place.For example, if interpolation, the deletion of conventional title or the change of title reproduction script of new title take place, then cause the above-mentioned renewal operation of index and obj ect file (index, MovieObject).
With above-mentioned explanation explicitly, be included in local stored files system architecture 41 and comprise the file structure that is used for the additional data that administrative institute downloads.For example, this document structure comprises " Org_id " catalogue for each content provider (CP) that additional content is provided, and comprises " Disc_id " catalogue for every particular plate in each " Org_id " catalogue." Disc_id " catalogue is configured to the form of hierarchy.Suppose that " Org_id# 1 " catalogue is confirmed as providing the catalogue of the specific company " A " of content, then come config directory " Disc_id # 1 " to " Disc_id # 3 " according to the disc-type that provides from " A " company, and the additional data that user's download is associated with " Disc_id# 1 " catalogue, the additional data of being downloaded is comprised in the binding unit contained in " Disc_id# 1 " above-mentioned catalogue.Those skilled in that art be it is evident that except that " Org_id " catalogue, the binding unit also can only be made of " Disc_id ".
The method of using above-mentioned bindings to constitute to be included in the virtual playlist file 63 in the virtual package is described to Fig. 9 below in conjunction with Fig. 7 a.
As mentioned above, virtual package has identical structure with Pan Bao.Especially, virtual package comprises the virtual playlist file 63 that newly is made of bindings.Reproduction/the management method of the virtual playlist file 63 by new formation, optionally original clip in the reproducing virtual bag (for example clip information file (01000.clpi)) and stream file (01000.m2ts), and/or optionally reproduce additional clip (for example clip information file (02000.clpi)) and stream file (02000.m2ts) in the local storage.
Therefore, be included in the basic reproduction/management document of virtual playlist file 63 conducts in the virtual package, to reproduce raw data that is recorded in the dish and the additional data that is recorded in local the storage simultaneously.
