detailed description

In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

Fig. 1 is a flowchart of an information processing method provided by an embodiment of the present invention. The execution subject of this embodiment of the invention is a control device, referring to Fig. 1, the method includes:

101: Obtain metadata information of media files of each terminal device;

Among them, the terminal device refers to all types of devices used to store files in household devices. The files stored on the terminal device can be called media files, and the types of the files can be video files, audio files, electronic documents and pictures, etc. Wait.

Among them, the metadata information refers to the information used to describe the media file, and the metadata information includes but not limited to the media file identifier (metaID), identifier name (identifierName), identifier keyword (identifierKeyword), media type (mediaType), media file Name (fileName) and other information that can be obtained from the media file itself, wherein the identification keyword can be selected by the user from the content of the metadata information of the media file during use, and can also be defaulted by the system.

It should be noted that the metadata information can also include a personal tag (personalTag), which is manually tagged to the media file by the user. The user can set the personal tag on the terminal device to achieve personal tagging on the media file on the terminal device. Personalized management, and because each terminal device sends metadata information to the control device, the control device can know the personalized label of each media file, so that by editing the personalized label, the media file on each terminal device can be personalized management.

Take the audio of the song "Red Bean" by "Faye Wong" as an example, the tag name is "Red Bean", the tag keyword 1 can be "Faye Wong", the tag keyword 2 can be "Red Bean", the media type is audio, and the media file name is "Red beans.mp3".

When the metadata information is obtained, it can be stored in the form of a list. For example, Table 1 is a metadata information table provided by an embodiment of the present invention. Table 1 records various contents that can be included in a piece of metadata information.

Table 1

The acquisition described in the embodiment of the present invention may be that each terminal device uploads its metadata information to the control device, or it may be that after the private cloud of each terminal device scans its corresponding terminal device, the scanned The metadata information of is uploaded to the control device, and the specific means of obtaining is not limited in this embodiment of the present invention.

102: Analyze the content of the obtained metadata information, and determine the metadata information that meets the association condition;

For the acquired metadata information of each media file, the contained content may be different. For example, for media file 1 on terminal device A, its metadata information can include: media file identification, identification name, media type, media file name; and for media file 2 on terminal device B, its metadata information The information may include: media file identification, identification name, media type. The embodiment of the present invention does not limit the specific content contained in the metadata information of the media file on each terminal device.

103: Establish an association relationship between the metadata information meeting the association condition.

Specifically, the establishment of the association relationship may be correspondingly storing metadata information that meets the association conditions on the control device, or by associating specified information in the stored metadata information in a mapping table to establish the matching association The relationship between the metadata information of the condition. Preferably, the association relationship between the media file identifiers in the metadata information meeting the association conditions is established, that is, a mapping table is established according to the media file identifiers of the metadata information meeting the association conditions, and the metadata information meeting the association conditions In terms of association, the association between metadata information of media files can be regarded as the association between media files. One media file can be associated with multiple metadata information, and one media file can also be associated with multiple media files. Therefore, there may be a many-to-many relationship in the association metadata information table. Table 2 is an associated metadata information table established according to media file identifiers in metadata information meeting the association conditions. Table 2 shows media file identifier 1 and its associated media file identifier 2 and media file identifier 3 .

Table 2

Further, when the control device receives a browsing request for metadata information, it displays the acquired metadata information on the display interface according to a preset method, and the preset method may be a list display of metadata information, a Metadata information with an association relationship is displayed correspondingly, which is not limited in this embodiment of the present invention.

Further, the control device can also provide operations such as storing, browsing, deleting, adding or modifying the metadata information acquired by the control device, so that users can manage the metadata information on the control device according to their own needs.

Further, when the control device receives a browsing request for the specified personalized tag, the control device obtains the metadata information with the specified personalized tag according to the specified personalized tag and returns it to the user, realizing the personalization of the personalized tag browse.

The method provided by the embodiment of the present invention acquires the metadata information of the media files of each terminal device, analyzes the content of the acquired metadata information, determines the metadata information meeting the association condition, and establishes the metadata information meeting the association condition relationship between. By adopting the technical solution provided by the present invention, it is possible to obtain the metadata information of media files on each terminal device to facilitate simultaneous browsing of media files on all terminal devices, and by analyzing the content of the obtained metadata information, By associating media files on terminal devices, users can obtain more detailed metadata information, making the description of media files multi-dimensional and specific.

Optionally, on the basis of the technical solution of the embodiment shown in Figure 1, step 102 "analyze the content of the obtained metadata information, and determine the metadata information that meets the association conditions", including 102a and 102b:

102a: Analyzing each item in the obtained metadata information;

In the embodiment of the present invention, this step 102a may include any of the following steps: (1) Analyze the identification name, media type and other content in all the obtained metadata information respectively, and compare the metadata of each media file Whether the content of the information includes the same content, so as to establish the relationship between the metadata information in the future; (2) analyze the identification name, media type and other content in all the metadata information obtained separately, and compare each Whether the metadata information content of the media file includes similar content, so as to establish the relationship between the metadata information in the future; (3) identify the identification name, media type, etc. in all the metadata information obtained Analyze and compare whether the metadata information content of each media file includes the same content, and compare whether the metadata information content of each media file includes similar content, so as to subsequently establish the association relationship between metadata information . It should be noted that due to the different requirements for the degree of association of metadata information, the comparison standard can be adjusted. When the requirement for the degree of association is fuzzy association, it can be directly compared whether there is similar content. When the requirement is accurate association, you can directly compare whether there is the same content, and when the requirement for association is to obtain the most association results, you can compare whether there is the same content while comparing whether there is similar content.

Wherein, comparing whether the metadata information contents of each media file include similar contents can be obtained by calculating the similarity between the metadata information contents of each media file.

Preferably, the analysis in step 102 can also be performed for specified items in the metadata information. Since the metadata information includes items that have little influence on the specific content of the file, such as the file size, only the metadata information can be analyzed The content of the specified item in , the specified content can be set by the technician during development, and can also be set by the user during use, which reduces the workload of analysis, and the user can adjust the associated items according to their own needs.

102b: When the acquired metadata information of the media file includes the same content, determine the metadata information corresponding to the same content as the metadata information meeting the association condition.

Wherein, including the same content in the metadata information of the media file obtained means that the content of one or more pieces of metadata information is the same. For example, the two pieces of metadata information are red beans and legends respectively. After comparison, it is found that the identification keywords included in the two pieces of metadata information are both Faye Wong, and the two pieces of metadata information include the same content.

In step 102b, only the situation when the metadata information includes the same content is described, but for the embodiment of the present invention, this step 102b can also be replaced by any of the following steps: (1) When the obtained When the metadata information of the media file includes similar content, the metadata information corresponding to the similar content is determined as metadata information that meets the association conditions; (2) when the metadata information of the obtained media file is neither When the same content and similar content are included, the metadata information corresponding to the same content and the similar content is determined as the metadata information meeting the association condition.

It should be noted that the above association is through the association of content, which is not limited by the type and format of the media file, so the association of metadata information of different types of media files (video, music, pictures) can be completed, and real Cross-type management of media files.

Optionally, on the basis of the technical solution of the embodiment shown in FIG. 1 , the step 101 "acquire the metadata information of the media files of each terminal device", and then include: using the metadata information of the media files of each terminal device At least one of the contents is a search keyword, and the synchronization information of the metadata information of the media files of each terminal device is acquired.

For the obtained metadata information of the media files of each terminal device, since the metadata information is obtained from the terminal device, the collection scope of the metadata information is fixed, so the metadata information lacks real-time performance. To improve the integrity of metadata information, synchronization information related to metadata information can be obtained by synchronizing metadata information.

Among them, the synchronization information includes but not limited to description information (information), publication date (publishYear), publisher (poster), area information (Area), actor (Actor), director (Director), lyrics (Lyric), script (script ), lines (line), album title (album). Table 3 shows a synchronization information table obtained according to the metadata information of the audio file.

table 3

For different types of media files, the corresponding synchronization information can be different. For example, for the synchronization information obtained according to the metadata information of the audio file, the synchronization information can be the information of a related audio file, and the synchronization information can include Singer, lyrics (Lyric) and poster (poster), etc., and when the synchronization information is the information of a related video file, the synchronization information can include actor (Actor), director (Director), area information (Area), etc. .

In the embodiment of the present invention, depending on the structure of the network system, the obtaining step may have any of the following situations: (1) Send a synchronization request message to the external cloud with at least one item in the metadata information as the search key , the synchronization request message carries a search keyword. When the external cloud receives the synchronization request message, it searches the Internet according to the search keyword, obtains the search result, and returns the search result to the controller as the synchronization information corresponding to the metadata information device, so that the control device obtains the synchronization information of the metadata information of the media files of each terminal device; (2) using at least one item in the metadata information as a search keyword, and sending the search keyword to the external cloud, so that the external cloud When the search keyword is received, search from the Internet according to the search keyword, obtain the search result, and return the search result to the control device as synchronization information corresponding to the metadata information, so that the control device obtains the information of the media files of each terminal device. Synchronization information of metadata information. Wherein, the external cloud can be a cloud server or a server cluster, and the external cloud can provide various functions including a search function for the control device. At this time, for the external cloud, its search function can be triggered when a synchronization request message is received , and the external cloud can also only provide a search function for the control device. At this time, for the external cloud, the search can be triggered by the received search keyword.

Further, the process of obtaining synchronization information may be performed periodically, such as at intervals of a fixed period of time, the process of obtaining synchronization information may also be triggered by the user, such as when a synchronization command is received from the user, The process of obtaining synchronization information. The embodiment of the present invention does not limit the specific manner of triggering the acquisition of synchronization information.

Preferably, using at least one item of the metadata information of the media files of each terminal device as a search keyword to obtain synchronization information of the metadata information of the media files of each terminal device, including:

Traversing the stored metadata information, using at least one item of unsynchronized metadata information in the metadata information of the media files of each terminal device as a search key to acquire synchronization information of the unsynchronized metadata information. Wherein, the synchronization state of the metadata information can be known through the synchronization flag (syncFlag) included in the metadata information. For example, when the synchronization flag is 1, the synchronization state of the metadata information is synchronized; when the synchronization flag is When 0, the synchronization state of the metadata information is not synchronized.

Further, when obtaining the synchronization information of the metadata information of the media files of each terminal device, modify the synchronization state of the metadata information of the media files of each terminal device to be synchronized, and the modification may specifically be to synchronize Flag is set to 1.

The method provided by the embodiment of the present invention acquires the metadata information of the media files of each terminal device, analyzes the content of the acquired metadata information, determines the metadata information meeting the association condition, and establishes the metadata information meeting the association condition relationship between. By adopting the technical solution provided by the present invention, it is possible to simultaneously browse the media files on all terminal devices by acquiring the metadata information of the media files on each terminal device, and by analyzing the content of the obtained metadata information, different The association of media files on the terminal device enables users to obtain more detailed metadata information, making the description of media files multi-dimensional and specific. Furthermore, in the case of incomplete media metadata information, the information on the Internet can be synchronized to the control device through the Internet, which further increases the dimension of metadata information to meet the needs of users for complete media metadata information and multimedia metadata. Multi-dimensional data requirements. .

Further optionally, on the basis of the technical solution of the embodiment shown in Figure 1, step 102 "analyze the content of the obtained metadata information, and determine the metadata information meeting the association conditions", including 102c:

102c: Analyze the acquired metadata information and the acquired synchronization information, and when the acquired metadata information and the acquired synchronization information include the same content, determine the synchronization information and the metadata information including the same content as Metadata information that meets the association conditions.

This step 102c is similar to the analysis process described in step 102b, and the only difference is that this step 102c is an analysis between the metadata information and the obtained synchronization information, so details are not repeated here.

For example, the synchronization information obtained according to the metadata information of the song "Red Bean" includes the singer "Faye Wong", the album name "Sing You", the profile of the singer "Faye Wong", etc. The singer "Faye Wong" and another If the identification keyword "Faye Wong" in the metadata information corresponding to the song "Emotional Life" has the same content, then "Emotional Life" and the synchronization information obtained from the metadata information of "Red Bean" are determined to meet the association conditions Metadata information, so that users can use the metadata information corresponding to "emotional life" to associate with the content of synchronous metadata information such as the album name "Sing You" and the profile of singer "Faye Wong".

Further optionally, on the basis of the technical solution of the embodiment shown in FIG. 1 , step 103 "establishing the association relationship between the metadata information meeting the association conditions" includes: The first synchronization information of the data information, query the locally stored metadata information, and when the metadata information corresponding to the first synchronization information already exists, combine the metadata information corresponding to the first synchronization information with the Metadata information association of the first media file.

Due to the limitations of metadata information, the media files that should have an association relationship on each terminal device may not be associated, and the user cannot know the association relationship it has. Therefore, after the synchronization information is obtained, the synchronization information can be further processed. deal with it. In this embodiment of the present invention, the metadata information of the first media file may be the metadata information of any file on any media device, and the first synchronization information is obtained by synchronizing with the metadata information of the first media file received synchronization information. Query the locally stored metadata information, and when the metadata information corresponding to the first synchronization information already exists, it is considered that a certain terminal device has a media file associated with the first media file, and the The metadata information corresponding to the first synchronization information is associated with the metadata information of the first media file.

For example, the synchronization metadata information of the audio "Red Bean" is obtained, the first synchronization information is the singer "Faye Wong", and the song "Legend" corresponding to the singer "Faye Wong" is found in the metadata information of the control device , that is, the "Legend" is stored on a terminal device in the home network, and the metadata information describing the two songs "Legend" and "Red Bean" is associated.

The method provided by the embodiment of the present invention, on the basis of the above embodiments, cross-correlates multiple metadata information with the obtained synchronous metadata information, so that the user can obtain more complete and detailed media information, and the media file The description is more specific and in-depth.

The private cloud reports the scanned media file information to the control device, so that the control device acquires the media file information of each terminal device.

The following is a description of the specific form of encapsulation of the metadata information of the media file "Red Bean" only in XML format:

101b: Analyze the media file information of each terminal device to obtain metadata information of the media file of each terminal device.

Wherein, after the control device acquires the media file information, it parses the media file information according to a specified format, and uses the content carried in the obtained media file information as the metadata information of the media file of each terminal device.

In the embodiment of the present invention, obtaining the metadata information by default includes the storage process of the metadata information, and the storage process can also be replaced by the following process: classifying the metadata information of the media files of each terminal device, and according to The categories are stored to the database of the controlling device. The classification may be performed according to any one or more items such as type, source terminal device, media file identifier, media file name, etc., which is not limited in this embodiment of the present invention.
