Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
According to embodiments of the invention, provide a kind of data adaptation method of video data.
Fig. 1 is that as shown in Figure 1, the method comprises according to the flow chart of the data adaptation method of the video data of the embodiment of the present invention:
Step S102 obtains the inverted index result set for video file from the inverted index file of the video file set up in advance.
The data model matching by the data source with multiple source, sets up and meets the data structure of searching for framework, thereby set up the inverted index file of video file.The externally query engine of (user) is provided, reception is for the retrieving information of video resource information, in described inverted index file, mate described retrieving information, according to the data inverted index result in the described inverted index file mating with described retrieving information, and the output packet inverted index result set that contains a plurality of video informations.
Wherein, the source channel of above-mentioned data source comprises: DB(video database), xml(extend markup language), file system etc.
Please refer to Fig. 2 below, further, step S102 can comprise the following steps:
Step S202, sets up the inverted index file of video file.
Particularly, by default participle mode, video file information is carried out to word segmentation processing and obtain keyword, set up keyword and there is the index relative between the video file information of keyword, thereby set up the inverted index file of video file.
Step S204, receives the retrieving information for video resource information.
Step S206 mates described retrieving information in described inverted index file.
Step S208, obtains inverted index result set according to the data in the described inverted index file mating with described retrieving information.
Step S104, carries out the adaptation processing based on polytype terminal according to default adaptation rule to described inverted index result set, and the video data that is suitable for polytype terminal is provided.
The inverted index result set obtaining is the basic data of consolidation form, if basic data is not carried out to adaptation processing, can not directly offer user and use.
Before execution step S104, need to set in advance adaptation rule, the video data of dissimilar terminal has different adaptation rules.In an embodiment of the present invention, described polytype terminal comprises: TV (intelligent television), mobile terminal, computer.Mobile terminal can be further subdivided into mobile phone and PAD again.
First, the data format of the video data of playing on these dissimilar terminal equipments is different, and playing video data also has other ask for something on these dissimilar terminal equipments, for example: copyright, data traffic, platform.According to the type of described terminal, set up the fitting relation of parameter and the data in described inverted index result set of described terminal, describe in detail below.
For same video data resource, for dissimilar terminal, there is respectively copyright.Specifically, video data resource can have copyright according to TV, mobile terminal (mobile phone and PAD), computer philosophy.When only, in the situation that obtain the copyright of all terminal equipments, can provide the video data of all types terminal equipment; If have the terminal equipment of a certain type not obtain copyright, the video data of the type terminal equipment can not be provided.
In addition, dissimilar terminal equipment is also different for the requirement of data traffic.Computer user generally surfs the Net by broadband connection, and data traffic is not had to strict restriction; And cellphone subscriber generally surfs the Net by modes such as 3G, more responsive to data flow-rate ratio.And dissimilar terminal equipment also has difference for the requirement of fault-tolerance, therefore, to video data, need to carry out above-mentioned adaptation processing according to terminal type, to meet the requirement of different user.
In present stage, some users' ISP(is ISP) be also different, for example, telecommunications and UNICOM.For these different ISP platforms, carry out the adaptation processing of video data, can bring different experience to user.
According to above-described embodiment, by obtaining the inverted index result set of video file, obtain basic data, and basic data is carried out to the adaptation processing based on terminal type, the video data that is suitable for polytype terminal can be provided.
According to embodiments of the invention, also provide a kind of data adaption system of video data.
Fig. 3 is according to the structured flowchart of the ordering system of the video resource information of the embodiment of the present invention, and as shown in Figure 3, described system at least comprises: acquisition module 10 and adaptation processing module 20, describe structure and the annexation of each module below in detail.
It couples adaptation processing module 20 mutually with acquisition module 10, for according to default adaptation rule, described inverted index result set being carried out to the adaptation processing based on polytype terminal, provides the video data that is suitable for polytype terminal.Particularly, adaptation processing module 20 is set up the fitting relation of parameter and the data in described inverted index result set of described terminal according to the type of described terminal.
With reference to figure 4, in one embodiment of the invention, on the basis of Fig. 3, described data adaption system also comprises: module 30 is set, and it couples mutually with adaptation processing module 20, for the adaptation rule of the video data of polytype terminal is set.
Wherein, described polytype terminal comprises: TV, mobile terminal, computer.Described adaptation rule is according to the following parameter setting of polytype terminal: copyright, data traffic, platform.It should be noted that, can adaptation rule be set according to an above-mentioned parameter in the present invention, can adaptation rule be set according to the combination of above-mentioned parameter yet, the present invention does not limit.
Continuation is with reference to figure 4, and described data adaption system also includes:
Set up module 40, it couples mutually with acquisition module 10, for setting up the inverted index file of video file.Based on this, acquisition module 10 is further used for, reception, for the retrieving information of video resource information, is mated described retrieving information in described inverted index file, according to the data in the described inverted index file mating with described retrieving information, obtains inverted index result set.
Wherein, set up module 40 and further comprise: keyword acquisition module (not shown), for the participle mode by default, video file information is carried out to word segmentation processing and obtain keyword; Inverted index is set up module (not shown), for setting up described keyword and having the index relative between the video file information of described keyword, thereby sets up the inverted index file of video file.
The operating procedure of method of the present invention is corresponding with the architectural feature of system, can cross-reference, repeat no longer one by one.
In sum, according to technical scheme of the present invention, by obtaining the inverted index result set of video file, obtain basic data, and basic data is carried out to the adaptation processing based on polytype terminal, thereby the video data that is suitable for polytype terminal is provided.
The foregoing is only embodiments of the invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in claim scope of the present invention.
