Embodiment
Fig. 2 is the block diagram of a disk player 200 according to an embodiment of the invention.Device 200 comprises a deriving means 210, a generating apparatus 220 and a playback engine 230.
Deriving means 210 is used to obtain the descriptor of a content to be played.Content to be played comprises the content to be played that is stored on the CD and the enhancing content relevant with content to be played on the CD.The enhancing content comprises the content in the network that the chained address is provided on the CD, also can comprise other storage mediums of this locality that on-link mode (OLM) is provided on the CD (as, hard disk, USB flash disk etc.) in content, for example some texts, still picture, animation, audio frequency, video segment or the like.The descriptor that deriving means 210 obtains comprises the canned data of above-mentioned content to be played, as content to be played memory address on CD or in local other storage mediums, the buffer-stored address in buffer of the content of perhaps from network, downloading to be played etc.For enhanced contents in networks, generally to download in the buffer of disk player to realize seamless play in advance, in buffer, this Web content obtains a buffer address.
If content to be played comprises Web content, for guaranteeing the smooth broadcast of Web content, the application resource of some network enabled content play also needs to download in the memory buffer of disk player, and obtains corresponding buffer-stored address so.Therefore, in this case, deriving means 210 also is used to obtain the playout software resource information of supporting content play to be played, and the canned data of application program for example is included in memory address in the network or the buffer-stored address in the buffer of disk player etc.
The descriptor that generating apparatus 220 is used for content to be played that deriving means 210 is obtained generates a played file system.Because comprised the descriptor of content to be played in the directory file system in the storage medium, so generating apparatus 220 can generate according to the directory file system of content to be played in storage medium, for example the directory file system of CD content on CD etc.Generally can be by the method for mapping or conversion, set up an initial played file system according to the directory file system that is stored in the content to be played on the CD earlier, and then the descriptor or the corresponding directory file system that will strengthen content join in the played file system that is built, thereby set up the unified played file system of content to be played in disk player, comprised the descriptor (as canned data etc.) of content to be played in the various storage mediums in this document system.
When content to be played comprises the network linking content, generating apparatus 220 also joins in this played file system with playing the required playing resource information of this corresponding network content to be played (as application program etc.), the canned data that is about to application program is mapped in the played file system, makes the store/buffer address link that has also comprised these application programs under the associative directory of this played file system.By setting up such played file system, can make the content to be played on the CD and strengthen content and play required resource to conduct interviews in a single mode and play.
For the content that must carry out caching process via buffer, if in buffer and have the buffer-stored address, generating apparatus 220 will join this information the played file system of establishment so.If this content is to download just to have the buffer-stored address in playing process, so, generating apparatus 220 will be brought in constant renewal in the played file system of being created in the dvd playback process.Therefore, device 200 can also comprise an impact damper (not shown), and the content to be played and the corresponding play-back application that are used for needs are carried out buffered are carried out buffered.
Fig. 3 is the process flow diagram of a kind of optical disc playing method according to an embodiment of the invention.At first, after a CD was inserted in the playing device, disk player will read the catalogue file of storing on the CD, had comprised some descriptors of content to be played in this catalogue file, and the information of corresponding playout software resource, as (step S305) such as canned datas.The purpose of this step S305 is to obtain the descriptor of content to be played, because comprised the descriptor of content to be played in the directory file system of content to be played in storage medium, therefore present embodiment can obtain the descriptor of content to be played easily according to the directory file system of content to be played in storage medium.Certainly, the method for other traditional descriptor of obtaining content to be played also is feasible.
Then, the directory file system according to the play content of inserting CD generates an initial played file system (step S310).According to the catalogue file on this CD, mapping generates an initial played file system.The process prescription of concrete generation played file system sees hereinafter Fig. 4 explanation for details.
This initial played file system comprises the directory file system that a mapping dirt becomes, and has and the corresponding directory file structure that is stored in the content to be played on the CD.For example, in the CD-disc catalogs file system, comprise " video transmission sub-directory (VIDEO TS) " and " enhanced contents sub-directory (DVD_ENAV) ", also comprised these two sub-directories so in this played file system accordingly.The link information that also comprises enhancing content to be played in the sub-directory of this initial played file system, these link informations are exactly the store path that points to this enhancing content to be played.If the application program that the broadcast of this enhancing content to be played need be stored in the CD supports that the canned data of these application programs also will be mapped in the associative directory of played file system so.
Then, obtain and strengthen the descriptor of content in local other storage mediums and join played file system (step S320).Because in the manufacturing process of CD, some descriptors of the content that this CD is stored, carried out defining and being stored in the CD as title, theme and some keywords etc., therefore as long as just can in local other storage mediums, find corresponding content to be played at an easy rate according to these information.The descriptor (for example memory address) of the enhancing content in these local other storage mediums is mapped in the played file system that has set up, points to the link information (as the memory address in local other storage mediums) that strengthens play content in local other storage mediums thereby this played file system has also been comprised.
Then, according to the descriptor update playing file system (step S330) of enhanced contents in networks.Usually, enhancing content in the network and corresponding playing resource (as the play-back application and the required application program of some other netcast of video, audio frequency) will download in the memory buffer of disk player row in advance again and play to guarantee seamless play, as at certain scene, provide the network server address that can obtain certain enhanced contents in networks (for example to link form on the CD with URL
Www.dvd_2.com.cn/video.exe); Just addressable and download this enhanced contents in networks and corresponding playing resource is carried out caching process according to these URL link informations, therefore except having network storage address information, after being downloaded, enhanced contents in networks and playing resource also have corresponding buffer-stored address.
According to the descriptor update playing file system of enhanced contents in networks of having downloaded and playing resource, be with these corresponding information, comprise that buffer-stored information joins in the played file system that is set up according to bibliographic structure.This played file system has comprised the link information that points to this buffer address of download content in buffer storage, for example,
File: //buffer:/Qffset=offset﹠amp; Length=length, wherein, buffer shows this content in buffer storage, and first address is offset, and length is length.Equally, this played file system also can comprise the descriptor of application resource in the direct sensing buffer storage.This step S330 can carry out in playing process.
At last, according to the played file system plays CD of being set up (step S340).According to this played file system, use single application programming interfaces to treat play content and play.As passing through the chained address dvd in the visit played file system: //dvdrom:/VIDEO_TS/VIDEO_TS.IFO, playing device just can obtain the path (being kept under the VIDEO_TS catalogue of DVD CD) of file VIDEO_TS.IFO, just can visit and play this document according to this path player.The foundation of played file system makes playback engine and concrete storage medium isolated, and to the play content on the different storage mediums, playback engine does not need to adopt different access modes to carry out again separately, has simplified the operation of Play System.
Need to prove that the enhanced contents in networks that is stored in the webserver not only can be downloaded before playing, also can in playing process, download in impact damper or local other storage mediums.After download finished, player was mapped to the buffer address of the netcast content of these downloads in the played file system, strengthened content thereby make player visit these by the buffer address link that provides in the played file system.
After dvd playback finished, player can abandon this played file system.Because when the played file system can dynamically be created in the CD insertion, therefore player can abandon this played file system automatically when playing end.But, consider that same Zhang Guangpan may be by repeat playing, therefore also can in playing end or playing process, this played file system be stored in local other storage mediums, when playing same Zhang Guangpan next time, just do not need to set up again a played file system like this, only need call already present played file system and can carry out dvd playback.
Fig. 4 is the bibliographic structure pie graph of played file according to an embodiment of the invention system.Player is set up an initialized played file system according to the directory file system of content on this CD.Suppose that the bibliographic structure of play content comprises a root directory on the CD, two sub-directories " enhanced contents sub-directory " and " video transmission sub-directory " are arranged under the root directory, should " enhanced contents sub-directory " also have secondary sub-directory " font sub-directory " and " page number sub-directory " down, all files are all preserved under separately the catalogue.For example, under " enhanced contents sub-directory " of CD, startup file is arranged, under " video transmission sub-directory " video transmission file etc. is arranged.
Because the bibliographic structure of played file system is corresponding with the bibliographic structure of CD, therefore the bibliographic structure with CD is mapped in the played file system totally, thereby makes the bibliographic structure of played file system identical with the CD-disc catalogs structure.As seen from Figure 4, the bibliographic structure of this played file system also comprises a root directory, " enhanced contents sub-directory " and " video transmission sub-directory " arranged under the root directory, also have " font sub-directory " and " page number sub-directory " down in " enhanced contents sub-directory ".Under these correlator catalogues, preserved the descriptor of dvd playback content, for example, the descriptor of having preserved startup file in " in the enhanced contents sub-directory " of played file system, the just canned data of this startup file.
This played file system also comprises the corresponding catalogue of bibliographic structure of local other storage mediums except comprising and the corresponding catalogue of CD-disc catalogs structure.When player searches has the related content of CD in local other storage mediums, then need the bibliographic structure of local other storage mediums also is mapped in the played file system.As can see from Figure 4, the catalogue that does not have in the bibliographic structure of former played file system, for example " audio frequency sub-directory " need join in the bibliographic structure of played file system and go, the descriptor of preserving audio file in should " audio frequency sub-directory ".And for the catalogue that has existed, as " enhanced contents sub-directory ", " font sub-directory " and " page number sub-directory " so only need with the file under these catalogues in local other storage mediums (as, Chinese font file, index file, clip file and page file etc.) path is mapped in the associative directory of this played file system.Preserve the store path of these files in the correlator catalogue of this played file system.If identical file is arranged under the same sub-directory,, then the descriptor of the new file " Chinese font file " in local other storage mediums is replaced original information as the descriptor of " Chinese font file " under " font sub-directory ".Like this, the complete foundation of catalog system file of this played file system.
Fig. 5 is the link synoptic diagram of played file according to an embodiment of the invention system, further specifies the link form that can be play by link that is stored in this played file system.This played file system can dispose according to URI and link, and for example, " file: // " URI configuration shows that this content is that some files can extract from local storage space; " http: // " URI shows that this content is positioned on the webserver, therefore can extract these contents with http protocol; " dvd: // " show that this content is positioned on the CD, so the specific application programming interfaces of CD can be used to extract these contents.And for the device identifier of " file: // " URI (as, buffer :/impact damper, hd :/hard disk, flash :/flash memory) also can be stored on any medium from physically discerning this play content.
As shown in Figure 5,, needn't be downloaded to impact damper earlier, only need dispose (method for expressing of appointed information position) according to URI and map directly to " video transmission sub-directory " down and under " enhanced contents sub-directory " for from the content on the CD.For example, the video transmission description information of files is preserved with " dvd: //dvdrom:/VIDEO_TS/VIDEO_TS.IFO " form, and this shows that the video file of CD is kept under the video transmission sub-directory of CD dvdrom, and filename is VIDEO_TS.IFO.For another example, the descriptor of startup file is kept in " enhanced contents sub-directory " with " dvd: //dvdrom:/VIDEO_TS/STARTUP.MLS " form, this shows that this startup file is kept under the video transmission sub-directory of CD dvdrom, and filename is STARTUP.MLS.
Though, play content on the CD can be downloaded, but also can be downloaded in advance in the impact damper for the play content in some CD, this part content can be picture, text or the audio frequency of some, the fragment of video etc., and this is for fear of player frequent redirect when playing these contents.This part content that is downloaded need be mapped under " enhanced contents sub-directory ", and its representation can be
File: //buffer:/Offset=offset﹠amp; Length=length, this shows that this file is kept in the buffer, and the buffer memory first address is offset, and length is length.
Play content for from local other storage mediums does not need to download yet, and the descriptor of this play content also can map directly under " enhanced contents sub-directory " according to the document form of URI configuration.For example, preserved a picture file relevant in local other storage mediums with CD content, so in the played file system with " file: //hd:/disc_a/file.ipg " form existence.This shows that this pictures is kept under the disc_a catalogue of hard disk, and filename is " file.jpg ".
For content from the webserver, need earlier play content or application resource to be downloaded to impact damper, it also can be mapped under " enhanced contents sub-directory " according to the descriptor that the document form of URI configuration will be downloaded content, for example, the descriptor that the text of downloading arranged with " file: //buffer:/Offset=0x3000﹠amp; Length=Ox1200 " the form preservation.This shows that this text is kept in the middle of the impact damper (buffer), and its first address is 0x3000, and length is 0x1200.For another example, the descriptor that the Chinese font file of downloading is arranged in " font sub-directory ", it with " file: //buffer:/Offset=0x0000﹠amp; Length=Ox1000 " the form preservation.This shows that this Chinese font file is kept in the middle of the impact damper (buffer), and its first address is 0x0000, and length is 0x1000.Perhaps also can represent without the document form of URI configuration, and directly to download the buffer address and the content-length at content place in the pointer form directed at buffer.
The present invention will be mapped in the played file system with the link unity of form with the outer content of CD on the CD, and playback engine can be operated on this played file system, and needn't directly manage various content source.Like this, the structure of playback engine just needn't be carried out big change, greatly reduces the design and the manufacture difficulty of playback engine.The more important thing is, when new agreement and media formats are introduced into, the dvd playback engine does not need to do change, only the corresponding software resource of deriving means and generating apparatus need be upgraded accordingly and expand and handle new agreement and medium are just passable, this has increased the versatility and the extendability of whole playing device.
The apparatus and method that present embodiment proposes can be suitable for multiple disk format, and for example eDVD form and blue-ray disc format etc. are all applicable.
Though through the present invention is described in conjunction with specific embodiments, for the skilled personage in present technique field, according to manyly substituting of making of narration above, revise with variation will be conspicuous.Therefore, when such substituting, in the spirit and scope that modifications and variations fall into attached claim the time, should being included among the present invention.
