| package metadata (meta-data pack)
+---title asset (title resource items)
|| title asset metadata (title resource metadata)
|+--movie asset (movie resource item)
|| movie asset metadata (movie resource metadata)
|| movie asset content (movie contents metadata)
|+--still-image asset (placard resource items)
|| box cover asset metadata (placard resource metadata)
|| box cover asset content (placard content metadata)
|+--preview asset (preview resource items)
|| preview asset metadata (preview resource metadata)
|| preview asset content (preview content metadata)

Step 160: the user receives the audio-video content of program request.
The user receives the described audio and video resource file that is linked on the video server by the terminal interface navigation selection.Particularly, the user selects one of them class in the class of terminal guidance interface display, enters such audio and video resource interface; Selective reception is linked to an audio-video content on the video server in such in described audio and video resource interface.
Fig. 2 is a preferred embodiment flow chart of the inventive method, and this embodiment is that example describes with the serial in the video request program:
Step 210: define the class of a serial as video request program.
In the video request program resource of existing magnanimity, wherein there are a lot of video resources to have common attribute, such as a serial that comprises a lot of collection of dramas, perhaps documentary film of a theme series or the like.A lot of information that these video resources with predicable comprise are identical, concerning a serial, wherein the director of each collection of drama, featured performer, brief introduction etc. are all identical, therefore a serial is defined as a class in the video request program, especially, present embodiment defines 40 current collections and looks serial " certain so-and-so " and be a class in the video request program.
Step 220: the metadata structure of constructing this serial.
Predicable in the class that defines is extracted, construct such normal metadata structure.Particularly, construct the title resource items of this serial according to the predicable of this serial, generate the placard resource items and the preview resource items of this serial then under the title resource items of serial, these resource items are combined constitutes the normal metadata structure of this serial;
Construct such special metadata structure according to the specific properties of different video resource in such.Particularly, construct the title resource items of each collection in this serial, under the title resource items of this collection, generate the collection of drama resource items of this collection, the placard resource items of this collection and the preview resource items of this collection; These resource items are combined constitute the special metadata structure of this serial; At last normal metadata structure and special metadata structure are combined the metadata structure that constitutes this serial.
Step 230: the meta data file that generates this serial according to metadata structure.
According to the title resource items in the normal metadata structure, placard resource items and preview resource items generate the title resource file respectively, placard resource file and preview resource file.Particularly, with TV series " certain so-and-so " is example, generate the title resource metadata according to the title resource items in the normal metadata structure, comprise TV play general collection number-40, the acute name of TV play-certain so-and-so, TV play director-director A, TV play featured performer-performer B, 1800 minutes TV play total times etc.; Generate the total placard resource metadata of this serial according to the placard resource items, comprise placard explanation, placard pixel-320 * 240 etc., and the placard content metadata that comprises placard content link address; Total preview resource metadata of this serial that generates according to the preview resource items, comprise time-10 minute of preview clip, the language-Chinese of preview clip, flow of preview clip etc., and the preview content metadata that comprises the preview video chained address.These metadata have constituted the public part of the meta data file of TV series " certain so-and-so ", and this part metadata has comprised 40 and concentrated the total attributes of each collection.
Generate title resource file, collection of drama resource file, placard resource file and the preview resource file of this collection of drama respectively according to title resource items, collection of drama resource items, placard resource items and the preview resource items of a collection of drama in the special metadata structure.Particularly, be example with TV series " certain so-and-so ", generate the title resource metadata of first collection according to the title resource items of 40 first collection of concentrating, comprise time-45 minute etc. of sign-1, this collection of title-first collection, this collection of this collection; Collection of drama resource items according to first collection generates the first collection of drama resource metadata that collects, and comprises the featured performer of this collection, the language of this collection, the video kind of this collection etc., and the collection of drama content metadata that comprises collection of drama resource video content chained address; Placard resource items according to first collection generates the first placard resource metadata that collects, and comprises the placard explanation of this collection, the placard pixel-320 * 240 of this collection etc., and the placard content metadata that comprises this placard content link address; Generate the preview resource metadata of first collection according to the preview resource items of first collection, comprise time-5 minute of preview clip, the language-Chinese of preview clip, flow of preview clip etc., and the preview content metadata that comprises this preview resource content chained address.Generate title resource file, collection of drama resource file, placard resource file and the preview resource files of two to 40 collection then successively respectively, more than the metadata of 40 collection constituted the special part of this serial meta data file.
Step 240: the meta data file and the packing of video content file of serial are generated the resource management system that general act sends to the external world.
Be kept under the general act after the video content file of video resource is packed with the meta data file of a class of aforementioned generation with in such, in the present embodiment, looking serial " certain so-and-so " with 40 current collections is example.This general act comprises: the video content file of this serial specifically comprises the total total playbill file of preview file, serial of preview file, the playbill file of each collection, serial of the collection of drama of the 40 video content files of concentrating each collection, each collection in the video content file; The meta data file of this serial specifically comprises the public part of the meta data file that generates according to the normal metadata structure and the special part of the meta data file that generates according to special metadata structure in the meta data file.
Step 250: extraneous resource management system sends meta data file and the video resource file in this serial general act respectively.
The general act of this serial is sent to extraneous resource management system, and extraneous resource management system sends to the video resource file in this serial on the ordering server.The total preview video that comprises this serial in this video resource file, the poster image of this serial, the video content of each collection, and the poster image of each collection; Extraneous simultaneously resource management system sends to the Web TV service platform with the meta data file in this serial.
Step 260: the meta data file of this serial of user terminal downloads.
When the user selects to watch the collection of one in this serial, the set-top box of user terminal is downloaded the public part of this serial meta data file and the special part of this collection from the Web TV service platform, collect the collection of drama content metadata that comprises this collection video content chained address in the special part by this, be linked to the corresponding video content of this collection on the ordering server.When the user wants to watch next collection, set-top box need not to download from the Web TV service platform the more public part of this serial meta data file, and only need download the special part of this collection, by comprising the collection of drama content metadata of this collection video content chained address, the corresponding video content that is linked to this collection on the ordering server gets final product.Needn't all download the public part of this serial meta data file so at every turn, improve the speed of set-top box download message, reduce the download of redundant data.
Step 270: the user watches the TV series of selection.
The video resource on the video server of being linked to of selection is watched in the terminal interface navigation of user by TV or computer.
The flow process that user terminal of the present invention obtains audio and video resource is as shown in Figure 3:
Step 310: enter the program request navigation interface after the beginning and select a class.
