Embodiment
The invention provides a kind of metadata analysis disposal route and mobile communication terminal of multimedia service.With reference to the accompanying drawings the useful embodiment among the present invention is described in detail.
Fig. 1 is the relevant structured flowchart of metadata analysis in the mobile communication terminal of the present invention; Fig. 2 is the synoptic diagram of the catalogue of the metadata among the present invention.
As shown in Figure 1, in the mobile communication terminal of multimedia service is provided, include in the structure that its metadata analysis is correlated with: pretreatment portion 10, it separates the multiple metadata that constitutes content of multimedia according to set standard, and each assigned indexes; Database 20, it is used to store the metadata and the relevant various information of index of separating by above-mentioned pretreatment portion 10; Analysis portion 30, it utilizes the index of storage in the above-mentioned database 20 and analyzes according to analysis request; Interface portion 40, it connects external treatment device (for example, keyboard or mouse etc.) and the database 20 that is used to transmit analysis request.
In addition, include in the above-mentioned database 20: data store 22, it is used to store each metadata of separating by above-mentioned pretreatment portion 10; Index stores portion 24, it is used for storing the index of each metadata of above-mentioned data store 22 storages.
The device that is used for analysis operation of the present invention that constitutes in as above structure, at first, isolate a plurality of metadata that comprise in the content of multimedia by pretreatment portion 10, and to each assigned indexes of metadata of above-mentioned separation, subsequently, the metadata of separating in the above-mentioned pretreatment portion 10 will be stored in the data store 22 of above-mentioned database 20, and above-mentioned pretreatment portion 10 middle finger standing wire fuses breath will be stored in the above-mentioned index stores portion 24 and manage.
Thus, when receiving user's analysis request, above-mentioned analysis portion 30 will detect the metadata and the relevant index of the information of user's input according to the index information of storage in the above-mentioned database 20, and only the information that comprises in the detected index is analyzed, will offer external device (ED) by above-mentioned interface portion 40 at last.
For example, the various metadata that comprise in the content of multimedia will be separated with form as shown in Figure 2, and be stored in the above-mentioned database 20 and manage.
Wherein, drawing symbol 100 is catalogues of metadata.Usually, metadata will be separated into: file layout 110; A plurality of information 120,140 and 160 that provide by above-mentioned pretreatment portion 10 separation; With above-mentioned a plurality of information 120,140 and 160 each corresponding index 130,150 and 170 of providing.
In addition, the index name in the diagram: SOF, App1, HDR and TIME are the present invention for convenience of description and help understanding of the present invention, and the index name among the present invention is not to be defined in this.
As shown in the figure, under the situation as the JPEG of image file, file layout 110 will be categorized as JPEG, as can provide information 120,140 and 160 be separated into width, highly, copyright etc. and each specify relevant index 130,150 and 170.That is, the width of jpeg file is included in the index of being appointed as SOF (Start Of Frame); Highly be included in SOF (the Start Of Frame) index; Under the copyright situation that has above-mentioned file, above-mentioned copyright will be included in the App1 index.
Thus, by the metadata catalog of aforesaid each associated documents, can confirm the positional information of associated metadatas such as " width of JPEG, highly be included in the SOF index, and copyright being included in the App1 index " easily.
And, as shown in Figure 2, under situation as the PNG of dynamic video file, file layout 110 will be categorized as PNG, information as width that information 120,140 and 160 can be provided and height correlation will be included in the IHDR index, and final time (Last Modified time) the relevant information of revising will be included in the TIME index.
Wherein, as the provided information in above-mentioned JPEG and the PNG file 120,140 and 160 enumerate width, highly, copyright, final modification time etc. separate form, but it can be according to file layout and sectionalization more, that is, the present invention is not the separation configuration that is defined among the aforesaid embodiment.
After carrying out above-mentioned lock out operation, when the user asks the relevant information of the width (width) of PNG file, to from database 20, detect the relevant index position of above-mentioned width information and confirm as the IHDR index, to only analyze simultaneously, thereby can shorten the required time of analysis operation the metadata that comprises in the above-mentioned IHDR index.
Operation to the metadata analysis disposal route in the mobile communication terminal of the present invention describes below.
Fig. 3 is the process flow diagram that is used to provide the metadata analysis disposal route of multimedia service in the mobile communication terminal of the present invention.As shown in the figure, at first, the metadata that comprises in the receiving multimedia content is also separated according to certain standard, specifies relevant index such as step S1, S2 in each reference position of above-mentioned separation simultaneously.
Then, various information that isolated metadata and index is relevant respectively are stored in the step S3 that manages in the data store 22 of database 20 and the index stores portion 24.At this moment, according to the multimedia file format of metadata, can will carry out integration management by the catalogues that constitute by a plurality of index that information are provided and are correlated with.
Subsequently, when the user is connected to mobile communication terminal and ask multimedia service or import the information of relevant content of multimedia, detect the form and the index S4 of the multimedia file of relevant metadata in the information that the various metadata that will store are correlated with from above-mentioned database 20, S5.
After carrying out above-mentioned detecting operation, confirm whether there is the historical record that detected index from database 20 is analyzed, when having relevant historical record, will from above-mentioned database 20, directly access the information of analyzing and provide; When not having relevant historical record, the index that visit is relevant is also only analyzed S6 to the required information that wherein comprises.
At last, the above-mentioned result who analyzes is offered outside user by interface portion 40.
Abovely provided the metadata analysis disposal route of the mobile communication terminal of multimedia service be illustrated being used among the present invention with reference to the useful embodiment among the present invention, but the present invention is defined in aforesaid embodiment, in the category that does not exceed basic fundamental thought of the present invention, the operator of relevant industries can carry out various deformation and application to it, and the above-mentioned distortion of carrying out and use and all to be under the jurisdiction of claim scope of the present invention.
