Detailed Description

Exemplary embodiments of the present application will now be described with reference to the accompanying drawings, in which various details of the embodiments of the present application are included to facilitate understanding, and are to be considered merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

The application provides a media information display method, which is applied to a terminal side in a specific example; of course, in an actual application scenario, the scheme of the present application may also be executed at the server side, where the server controls the display condition of the terminal, for example, the control terminal displays the target media information in the playing process of the video clip. Specifically, fig. 1 is a schematic flow chart of an implementation of a media information display method according to an embodiment of the present application, as shown in fig. 1, the method includes:

step S101: and acquiring target comment information input by a user in the process of browsing the multimedia data.

Step S102: and acquiring video clips which are selected from preset multimedia resources corresponding to the multimedia data and matched with the target comment information.

Step S103: and selecting target media information which is at least matched with the target comment information from a preset media information resource.

Step S104: and displaying the target media information in the playing process of the video clip.

Therefore, the video clip matched with the comment information and the media information can be obtained based on the comment information matching of the user, the media information matched with the video clip is played in the playing process of the video clip, and further accurate display of the media information is achieved, and therefore user experience is improved.

In practical application, when the scheme of the application is executed at the terminal side, the terminal stores preset media information resources in advance at the moment, and the function similar to a small database is realized, so that on one hand, the query speed can be improved, on the other hand, the time delay of requesting the media information resources from the server is avoided, and the problem of media information display delay is fundamentally relieved.

In practical application, it should be noted that, when the scheme of the present application is executed at the terminal side, at this time, after the terminal obtains the target comment information input by the user in the process of browsing the multimedia data, the target comment information is sent to the server, the server is responsible for selecting a video segment matching with the target comment information from the preset multimedia resource corresponding to the multimedia data, and sending the selected video segment to the terminal, and then the terminal is responsible for selecting at least the target media information matching with the target comment information from the preset media information resource, and controlling the target media information to be displayed in the playing process of the video segment.

In practical application, step S103 may further consider other practical factors when determining the target media information, where the factors may be set according to the practical application scenario, for example, target media information matching with the target comment information is selected from preset media information resources, and meanwhile, the target media information meets the preset rule.

In a specific example of the solution of the present application, the preset multimedia resources include: the multimedia data browsed by the user; and/or other multimedia data having an association relationship with the multimedia data. For example, in a specific scenario, the multimedia data browsed by the user is a live video of a host, at this time, other multimedia data having an association relationship with the multimedia data may be specifically other live videos of the host, or historically played videos, etc., so that the purpose of selecting media information matching with the video played by a specific host for the specific host is achieved, and the process is automatically performed based on comment information, without the host having to passively search for the media information; moreover, the matching degree of the video played by the anchor and the media information is improved, and a foundation is laid for improving user experience.

Therefore, on one hand, the selection resources of the video clips are enriched, and on the other hand, the method lays a foundation for enriching application scenes and improving user experience.

In a specific example of the present application, the step S101 of obtaining the target comment information input by the user in the process of browsing the multimedia data may specifically include: acquiring a plurality of comment information input by a user in the process of browsing multimedia data; that is, in a scene, there are a plurality of comment information, and at this time, a plurality of comment information for the multimedia data may be acquired, where the comment information may be input by the same user or may be input by different users. Further, based on the repeated features of the comment content (i.e., the number of occurrences of the comment content) in the comment information, the plurality of comment information is subjected to sorting processing, for example, descending sorting; and determining target comment information from the comment information based on the sorting processing result, for example, taking one or more comment information with the largest occurrence number as the target comment information. Therefore, on one hand, the video clips which are interested by the user can be determined to the greatest extent, on the other hand, a foundation can be laid for selecting target media information for the video clips which are interested by the user, further, a foundation is laid for playing the video clips which are interested by the user to the greatest extent and playing the target media information matched with the video clips, and meanwhile, a foundation is laid for improving user experience.

In a specific example of the scheme of the present application, in the process of displaying media information, the following factors may also be considered, and specifically, the following two modes may be adopted for displaying, where:

Mode one: the step S104 further includes: acquiring a display form of the target media information; at this time, in the step S104, the displaying the target media information during the playing process of the video clip specifically includes: and displaying the target media information in the display form in the playing process of the video clip. Therefore, a foundation is laid for enriching the display form of the media information and maximizing the custom display form.

In the second mode, the step S104 further includes: determining target multimedia data corresponding to the video segment, and determining the starting time of the video segment in the target multimedia data;

At this time, in the step S104, the displaying the target media information during the playing process of the video clip specifically includes: and in the process of playing the target multimedia data, playing the target media information in a time period corresponding to the starting time. Therefore, in the process of playing the target multimedia data, the media information is inserted, and meanwhile, the inserted media information (namely the target media information) is matched with the currently played video clip, so that the user experience is further improved, and a foundation is laid for accurate playing of the media information.

In practical applications, the target media information is displayed in the whole time period corresponding to the start time, or at least in part of the time period corresponding to the start time.

It should be noted that in practical applications, the two modes may be alternatively executed or synchronously executed (the execution order is not limited), for example, the obtained display form is used to play the target media information in the time period corresponding to the start time in the process of playing the target multimedia data, so that the display form is enriched, applicable application scenarios are enriched, and meanwhile, user experience is improved.

In a specific example of the present application, the selecting, in step S103, the target media information at least matching with the target comment information from the preset media information resources may specifically include: acquiring content characteristics corresponding to each piece of media information in a preset media information resource, such as keywords representing the content characteristics, such as types of each piece of media information, corresponding scenes and the like; and then at least selecting target media information with content characteristics matched with the target comment information from the preset media information resources, so that the content of the selected target media information is matched with the target comment information, the correlation of the selected target media information and the target comment information is further improved, and the viewing and browsing experience of a user is improved. Meanwhile, the matching target media information can be selected for the video clips interested by the user to the maximum extent, and a foundation is laid for the maximum display of the target media information matched with the target comment information and the target media information matched with the video clips.

The scheme of the application is further described in detail by combining specific examples, and specifically, the example can maximally improve the exposure rate of the media information, thereby laying a foundation for improving indexes such as subsequent click rate, conversion rate and the like. Specifically, the method adopts a big data mode to acquire target comment information with the largest occurrence number in comment information such as a barrage input by a user, a scene corresponding to the target comment information can be regarded as the scene which is most attractive to the user, and then media information corresponding to the scene (namely, target media information matched with the target comment information) is screened out and displayed in a big data matching mode, so that a foundation is laid for the subsequent improvement of the exposure rate, click rate and conversion rate of the media information.

The specific idea is as follows: the video company maintains a rich media information base (namely preset media information resources), and pre-distributes the rich media information base to the terminal for local storage, then guides users to comment in the video playing process, screens out a plurality of groups of comment contents with the largest occurrence number from the comments to serve as target comment information in a fuzzy matching mode, searches video fragments matched with the target comment information according to the target comment information, and searches target media information matched with the target comment information, and at the moment, the target media information is matched with the content or scene of the video fragments; and finally, displaying the target media information in the playing process of the video clip. As shown in fig. 2, the specific flow is as follows:

Step 201: the video company (corresponding to the server side) has a playing entrance and enough capability to find the media information business to cooperate, based on which the video company can maintain a large media information base (i.e. preset media information resources) and issue the media information base to the terminal for local storage, wherein the mapping relation between the media information and the content characteristics (such as corresponding scenes and the like) is configured in the media information base.

Step 202: the video company (i.e. the server) provides video resources for users to play, guides the users to comment or send out the barrage in the process of browsing videos by the users, acquires the comment or the barrage sent out by the terminal side, screens out the content with the number of occurrence ranking being in the preset number as target comment information, and sends the content to the terminal.

Step 203: the video company searches for video clips matching the target comment information in the video resources maintained based on the target comment information, such as searching for video clips matching the scene and language of the target comment information from the video resources.

Here, in the actual scene, only the video clips matching with the target comment information can be queried in all video resources of the anchor corresponding to the video browsed by the current user, so that the media information matching with the video played by the anchor can be found.

Step 204: after determining the video clip matched with the target comment information, sending the video clip to the terminal, and simultaneously, searching the media information (namely the target media information) which is most suitable for the video clip, namely the target comment information, from a locally maintained media information base at high speed by the terminal, and displaying the media information in a highly customized mode in the playing process of the video clip.

In practical application, the video company can also acquire the display condition of the target media information and the click condition of the user through data statistics.

Further, the scheme of the application is further explained by specific scenes, for example, a user watches a video of a food anchor, and the marked action of the anchor is my God, and the anchor is good in eating. There are a large number of reviews under all videos of the anchor that send and eat xxx, know xxx as soon as the host sees that the review is good, and so on. At this time, by using the scheme of the application, the content with the largest occurrence number in the comment can be classified in a fuzzy way and is classified into a plurality of keywords (namely target comment information), then the keywords are used for searching the video clips matched with the keywords in the video resource, and the starting time points and the ending time points of the video clips are determined. Meanwhile, scene matching monitoring is performed in the media information base based on the keyword, and the most suitable target media information is matched, for example, the target media information contains? Then the xxx products are eaten. Further, the target media information is presented during a period of time at the beginning and ending time points of the video clip.

In practical applications, the implementation of this example requires at least the following support of several core technologies, including:

firstly, the media information (namely a media information base or preset media information resources) of several core categories is pre-issued to a terminal in advance for caching, so that the problem of time consumption of inquiry of a server is prevented.

And secondly, carrying out the classification of related comment data and the extraction of keywords based on comment content by a big data technology.

Third, video segment monitoring techniques, i.e., monitoring video segments corresponding to a keyword in a video asset based on the keyword, are implemented, for example, using artificial intelligence models.

Fourth, the quick search technology, namely, according to different scenes, carries out quick search matching in the media information base, and then determines the media information most suitable for the scene.

Based on the technical support, compared with the prior art, the video clip which is most concerned by the user can be extracted, and the most appropriate media information can be displayed in the playing process of the video clip, so that the problems of media information resource deficiency of a video company, mismatching of video content and media information or excessively single media information are greatly reduced, and the cost of selecting the media information is saved; meanwhile, the matching degree of the user and the displayed media information is greatly advanced, the whole process is automatically realized, and the flexibility is high.
