Though do not show among Fig. 6,, bind unit 400 for one that not only is used for each storage medium, and the share directory of sharing in the storage medium that can in identical studio, make, can be present in the local storage 260.Therefore, the storage medium identifier disc_ID that promptly is used in the content in the share directory is different from the disc identifier of Pan Bao, when their studio identifier org_ID is identical, also can bind the content and the described Pan Bao that are stored in the share directory, to produce virtual package 600 as shown in Figure 6.
In addition, can there be the share directory that in the different storage medium of its studio identifier org_ID, to share.In this case, can bind the content that is stored in share directory and the storage medium 250, to produce virtual package 600 with different studio identifier.Suppose to exist following multiple situation: the file with same file name is present in (a) in the storage medium 250; Be present in the binding unit 400 in the local storage 260 (b); Be present in the share directory that in storage medium, to share (c) with identical studio identifier org_ID; Be present in the share directory that in storage medium, to share (d) with different studio identifier org_ID.In this case, the priority of binding is present in situation (b), (c), (d) and order (a) according to file and determines.
Simultaneously, according to each embodiment of the present invention, be stored in binding unit 400 in the local storage 260 and comprise inventory file 410 as binding information.Inventory file 410 can comprise at the binding information of describing after a while.
Fig. 7 is the diagrammatic sketch of inventory file 410A that is used to produce virtual package according to the embodiment of the invention.With reference to Fig. 7, inventory file 410A comprises studio identifier org_ID 710 and is used to verify whether inventory file 410A can be used for the storage medium identifier disc_ID 720 of storage medium 250.In addition, inventory file 410A comprises directory information 730, directory information 730 is used for illustrating whether the catalogue that downloaded contents file and inventory file 410A will be stored in wherein is the binding unit area of local storage 260, be used for perhaps illustrating that described catalogue is to be present in still to be present in the share directory that can share in the storage medium with different studio identifier org_ID in the share directory that the storage medium with identical studio identifier org_ID is shared.In addition, inventory file 410A comprises a plurality of content informations 740 that constitute the binding unit.Otherwise described a plurality of content informations 740 can belong to heading message.
Content information (or heading message) 740 can comprise content identifier information (content_ID) 742 that is used to distinguish the content that differs from one another and the use information 744 that is used for the use of instruction content.For example, content information 740 can comprise the use information about the use of content (as Korean text captions or Japanese text captions).In addition, content information 740 can comprise the information about all files relevant with content.For example, content information 740 can be specified for example filename about each file, size of data and the version information from as shown in Figure 3 Index.bdmv file to the xxxxx.m2ts file of constitution content or title.As described in conjunction with Fig. 7, inventory file 410A comprises the binding downloaded contents and is recorded in the content on the storage medium 250 so that described content can be reproduced required information together.
Therefore, when downloading content, preferably download inventory file 410A, so that inventory file 410A can comprise up-to-date information by the java application that is used to download.Use the directory information of inventory file 410A to determine that preferably data downloaded will be sent to the catalogue of its local storage 260 from the temporary storage area.In addition, when the Pan Bao of storage medium 250 and the binding unit 400 of local storage 260 are bundled in a time-out, inventory file 410A is used for determining whether binding unit 400 is suitably stored.That is to say the content information 740 of inventory file 410A is preferably used for determining whether the All Files that produces binding unit 400 is suitably downloaded.
Now another embodiment of the present invention will be described.This embodiment is that above-mentioned binding is stored in the content in the storage medium 250 and is stored in content in the local storage with the application of the method that produces virtual storage medium and reproducing virtual storage medium.The method according to this invention is similar to following content stream.
Thereby when the less downloaded contents at short notice of data stream (additional menu, captions etc.) is downloaded and main video data in being stored in storage medium 250 when binding, be favourable according to the method for previous embodiments of the present invention.
Yet, when downloading bigger content (introduce the propaganda film of New cinema or about movie manufacturer or performer's comment), when the operation that changes such as title takes place when, according to method needs plenty of time of previous embodiments of the present invention with about all data storage of described content in the temporary storage area, upgrade for example binding unit 400 shown in Fig. 4, produce for example virtual package shown in Fig. 6 600, carry out then and reproduce operation.
Fig. 8 is the diagrammatic sketch according to the progressive playlist 810 that is used for download and reproducing part audio frequency-vision (AV) stream file 820 of the embodiment of the invention.With reference to Fig. 8, under the situation of the java application that allows the progressive playlist 810 of download,, also can begin to reproduce operation even only downloaded the bigger stream file 820 of a part that will at first be reproduced.
As shown in Figure 8, when finishing progressive playlist 810 of download and clip information file, be used for whole stream files that actual reproduction is operated, also carry out bindings to produce virtual package even without download.
That is to say, when producing virtual package 600,, also must produce virtual package 600 even all stream files (that is, the m2ts file) are not present in the binding unit 400 by using progressive playlist 810 to upgrade binding unit 400.Therefore, need to distinguish the bindings of using progressive playlist 810 and the additional information of using the bindings of common playlist.
Fig. 9 is the diagrammatic sketch of exemplary inventory file 410B that is used to reproduce progressive playlist according to the embodiment of the invention.Say that at length Fig. 9 shows the structure of the inventory file 410B that uses when the Pan Bao by binding storage medium as mentioned above and the binding unit 400 in the local storage 260 produce virtual package.With reference to Fig. 9, inventory file 410B also comprises: studio identifier org_ID 910; Storage medium identifier disc_ID 920, are used to verify whether inventory file 410B can be used for storage medium 250; Directory information 930, be used for illustrating whether the catalogue that downloaded contents file and inventory file 410B will be stored in wherein is the binding unit area of local storage 260, be used for perhaps illustrating that described catalogue is to be present in still to be present in the share directory that can share in the storage medium with different studio identifier org_ID in the share directory that the storage medium with identical studio identifier org_ID is shared; And a plurality of content informations 940 that constitute binding unit 400.
In addition, do not exist stream file also with the information of reproducing virtual bag even inventory file 410B also can comprise indication when determining whether suitably to produce the binding unit, described information is about using the bindings of progressive playlist.That is to say, progressive information is added in the content information 940 that is included among the inventory file 410B, thereby even stream file is not present in the binding unit catalogue of local storage 260, but also reproducing virtual bag 600.The All Files of content corresponding is the data that are used to bind of flow data form.
Figure 10 is the diagrammatic sketch that upgrades processing according to the exemplary binding unit of the progressive playlist of the use of the embodiment of the invention.With reference to Figure 10, under the situation of the bindings of using progressive playlist, in case finish the download of database file (play list file and clip information file) about video data, then can be not upgrading for example binding unit 400 shown in Fig. 4 under the situation such as the stream file of m2ts, to produce for example virtual package shown in Fig. 6 600.Therefore, during reproducing progressive playlist, according to the java application that is used to download, also other streams of not downloading are stored in the temporary storage area of the local storage 260 in the exemplary reproducer 200 shown in Fig. 2 for example.
During title changes or is converted to top menu, handle with reference to the binding unit renewal of Fig. 5 A and Fig. 5 B description more than preferably before upgrading virtual package, carrying out.Yet, as shown in figure 10, do not change because title takes place during reproducing progressive playlist, so the stream file that is stored in the temporary storage area can not be moved to the binding elementary data areas.Therefore, when reproducing progressive playlist, the java application that is used to download can upgrade binding unit 400 via Binding Update application programming interfaces (API) when finishing the download stream file.
