Implementation

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

For the sake of brevity and clarity of the description, the aspects of the present invention are set forth below by describing several representative embodiments. Numerous details in the examples are only provided to aid in understanding the aspects of the invention. However, it is obvious that the technical solution of the present invention can be implemented without being limited to these details. In order to avoid unnecessarily obscuring aspects of the present invention, some embodiments are not described in detail, but only the framework is given. Hereinafter, "including" means "including but not limited to", and "according to" means "at least according to ..., but not limited to only based on". When the number of one component is not specifically indicated below, it means that the component may be one or plural, or may be understood as at least one.

It should be noted that, in the present application, the media content hereinafter may specifically refer to multimedia content such as video, audio, and pictures. There are currently many types of media content search methods. One type of search method is based on keyword prompts. Specifically, when receiving the prefix of the target media content name input by the user through the terminal, such as the prefix of the movie drama name, the network side server may associate various possible query keywords according to the prefix, and pull through the user terminal The way of the list shows each query keyword to the user. Wherein, the above prefix refers to the previous word or words of the name of the target media content. When the user selects one of the query keywords, the network side server performs an actual search according to the query keyword, obtains a search result of the media content information including one or more media contents, and displays the search result to the user through the terminal. There is also a type of search method that displays the search result and the information of the static content of the media content in addition to the name of the searched media content. However, no matter which search method is used, if there are multiple cases with similar play names, the user needs to make a selection among a plurality of candidate keywords and then search. Also browse and find the media content you want in the searched candidate media content. Usually if the search finds that the content is not what you want, you will most likely need the user to retype the keyword to search separately. Such a process usually fails to determine the accuracy of the search because the user cannot obtain more information, so that the user repeats the operation, the user experience is not smart and convenient, and also causes waste of resources.

In order to solve the above problem, an example of the present application proposes a media content search method. In the method, after the user inputs a part of the keywords of the target media content through the application client, the application client displays the media content information of the candidate media content searched by the server to the user, and after the user selects to preview a certain media content, The summary file of the media content returned by the playback server simulates the video playback effect in a key frame animation rotation manner, so that the user can quickly preview the media content to determine whether the media content is the media content desired by the user. Such a media search method can improve the efficiency of the user searching for the media content, and improve the user's experience of quickly finding the media content through the search, thereby saving the hardware resources of the terminal side and the network side device and the network resources occupied by the communication. Here, part of the keywords of the target search content may refer to a part of the media content name. For example, "speed" or "passion" in the name of the movie "Speed and Passion 8" may be searched as part of the keyword input.

FIG. 1 is a schematic structural diagram of a media content search system to which a media content search method according to some embodiments of the present application is applied. As shown in FIG. 1, the media content search system of the present application includes at least: a user terminal 11, a network 12, and a server 13.

In some examples of the present application, the user terminal 11 may be a personal computer, a notebook, or a smart terminal device such as a tablet computer, a smart phone, or a PAD. The user terminal 11 includes a display device such as a liquid crystal screen. Generally, various application clients, such as application clients such as Tencent video, can be installed on the user terminal 11. The application client can obtain corresponding media content from the server 13 and display it to the user on its own display device.

The server 13 is an application server corresponding to the application client, and may be, for example, a Tencent video server or the like. The application server software in the server 13 provides services to the user together with the application client software in the user terminal 11, for example, determining media content such as content that needs to be previewed based on keywords. The above server 13 may be a separate server or a cluster server composed of a plurality of servers.

Network 12 can include wired networks and wireless networks. As shown in FIG. 1, on the access network side, the user terminal 11 can access the network 12 by way of wireless or wired; on the core network side, the server 13 is generally connected to the network 12 by wire. . Of course, the server 13 can also be connected to the network 12 wirelessly.

The media content search method provided by the example of the present application will be described below with reference to the accompanying drawings.

Based on the system structure shown in FIG. 1 , an embodiment of the present application provides a media content search method, which is applied to an application client of the user terminal 11 , and the method displays at least a keyword searched by a keyword to the user. After a list of media content, in response to the user's preview request operation for one media content, the preview information of the media content is displayed, and the user is provided with more rich information for the user to determine whether the media content is the media content required by the user. Thereby, the efficiency of the media content search is improved, and the hardware resources and network resources of the user side device and the network side device are saved.

FIG. 2 shows a flow chart of a media content search method provided by an example of the present application. The media content searching method is performed by a user terminal. As shown in FIG. 2, the method includes the following steps:

Step 201: Receive a media content search request that carries a part of the keyword, and send the partial keyword to the server for media content search.

In some embodiments, the user may search for the media content through the application client on the user terminal 11 in order to find the media content it needs, which may also be referred to as the target media content. Specifically, the user can usually input a partial keyword in the search box provided by the client on the user terminal 11 and click the search button to send a media content search request to the application client. At this time, the application client sends the partial keyword input by the user in the search box to the server in response to the media content search request, so that the server performs media content search according to the partial keyword to determine the media content corresponding thereto.

Step 202: Receive media content information of one or more media content that is fed back by the server.

Here, the media content information is information that can be used to describe the characteristics of the media content, including one or more of the name, type, main actor, storage address of the media content, and poster information of the media content. Generally, the server searches for the media content according to some keywords uploaded by the application client, obtains the media content information of the searched media content, and feeds the obtained media content information of the media content to the application client.

In the embodiment of the present application, in addition to the media content information of the media content, the server may further feed back the storage address of the digest file corresponding to the searched media content.

In an embodiment of the present application, the summary file may be a media file corresponding to the media content generated by the server according to a plurality of key frames extracted from one media content. For example, the server may take a screenshot of a media content at a fixed time interval a (such as every 10 seconds), obtain multiple screenshots, and splicing a predetermined number of multiple screenshots in a certain order and splicing rules to obtain one or more Large picture file. Each large picture file can be used as a summary file of the above media content. Generally, each media content can have one or more summary files. For another example, the server may take a screenshot of a media content according to a fixed time interval a (such as every 10 seconds), obtain multiple screenshots, and then generate an animation file according to the obtained multiple screenshots, and use the animation file as the above. A summary file of media content. After the server generates the above summary file, it stores it in its own database and records the storage address of the summary file. For example, the storage address of the above digest file may be a uniform resource locator (URL) that identifies the storage location of the digest file.

Step 203: Display media content information of the one or more media content.

In some embodiments of the present application, the application client may display the media content information of the one or more media content by way of a list. For example, FIG. 3 shows an example of displaying media content information of media content in a list form. As shown in FIG. 3, the application client receives the media content "Speed and Passion 8", "Speed and Passion 7", "Speed and Passion 6" corresponding to the "Speed" of the partial keyword 301, and displays it in a list form. The media content information of each media content is displayed in the above list, for example, the name 302 and the category 303 of each media content.

Step 204: Download a summary file of the media content in response to the user's preview request for a media content, and play the summary file of the media content in a preview window corresponding to the media content.

In an embodiment of the present application, when the application client displays the media content information of the one or more media content, the user may further display a preview window for displaying the media content for the user for each media content. Poster or abstract file.

Specifically, when the application client displays the media content information of the one or more media content in a list manner, the application client may set a display area for each media content on the page for displaying the media content of the media content. information. At this time, the preview window may be set at a predetermined position within the display area of each media content.

In some embodiments of the present application, in order to reduce the layout of each media content, in order to display more media content of the media content in the same page, as shown in FIG. 3, the application client passes the list. When the media content information of the one or more media content is displayed, a part of the media content information of the first or multiple media content, such as a name and a type, may be displayed on the page in a manner instead of displaying the media content. The entire content of the information and the preview window. At this time, if the user wants to view all the media content information of a certain media content and the preview window, it is necessary to send an expansion request for the media content. For example, as shown in FIG. 3, when the application client displays the media content information of the one or more media content in a list manner, an expansion symbol 304 is displayed corresponding to each media content. The user clicks on the expansion symbol 304 corresponding to a certain media content to trigger an expansion request for the media content. As an alternative, the application client may not display the expansion symbol 304 corresponding to each media content. In this case, the expansion request may be triggered by a click operation of the user to click part of the media content information of a certain media content, or It can be triggered by a sliding operation of the user's mouse to a portion of the media content information of a certain media content. Regardless of which triggering method is employed, in response to a request to expand a media content in the list, the application client will expand a display area displaying the media content and present a preview window of the media content within the display area And all media content information of the media content.

As previously mentioned, the preview window described above is used to present a poster or abstract file of the media content to the user. When the user sends a preview request to request preview of the media content, the application client will play a summary file of the media content for the user through the preview window.

In the embodiment of the present application, the preview request may also be triggered in multiple manners. For example, when the application client displays the media content information of a certain media content, the poster of the media content may be statically displayed in the preview window. A preview button is also provided. The preview request is triggered when the user clicks on the preview button. For example, Figure 4 is an example of expanding the display of one piece of media content information. As shown in FIG. 4, in response to the user's deployment request, specifically, for example, clicking on the selection operation of the media content 401 "Speed and Passion 8", the display area 402 of the media content is expanded, and the media content is displayed in the display area 402. The preview window 403 of 401 and media content information, such as name 404, starring 405, etc., also provides a play button 406. Further, the preview window 403 can statically display the poster (shaded portion) of the media content and provide a preview button 407. When the user clicks the preview button 407, it means that the user has sent a preview request. As an alternative, the preview button may not be set, and the preview request may be triggered by the user clicking a part of the media content information of a certain media content or a click operation of a certain position in the preview window area; or may be mouse-slid by the user. Triggered by a portion of the media content information of a certain media content or a sliding operation within the preview window area.

As described above, in an embodiment of the present application, in response to a user's preview request for a media content, if the storage address of the media content summary file has been known, the application client will according to the media content summary file. The storage address downloads a summary file of the media content, and plays a summary file of the media content in a preview window. In an embodiment of the present application, in response to the user's preview request for a media content, if the storage address of the media content summary file is not known, the application client first requests the storage address of the media content summary file from the server, After obtaining the storage address of the media content summary file, downloading the summary file of the media content according to the storage address of the media content summary file, and playing the summary file of the media content in the preview window. When requesting the storage address of the above summary file, the application client may carry the identification information such as the name of the media content to identify which storage address of the media content summary file is currently requested.

As described above, the above summary file may be a media file corresponding to the media content generated by the server based on a plurality of image frames extracted from one media content.

In some embodiments of the present application, the digest file may be a server that takes a screenshot of a piece of media content at regular time intervals (such as every 10 seconds) and generates an animation file based on the obtained plurality of screenshots. At this time, playing the summary file of the media content in the preview window specifically refers to playing the animation file in the preview window.

In some embodiments of the present application, the summary file may further be that the server screens a media content at a fixed time interval (such as every 10 seconds), and splicing the obtained multiple screenshots in a certain order to obtain one or Multiple image files, referred to herein as large image files. At this time, playing the summary file of the media content in the preview window specifically refers to automatically rotating each screenshot in the large picture file in the preview window. The above automatic carousel refers to automatically playing each of the screenshots included in the large picture file in a predetermined order and time interval.

In some embodiments, automatically rotating the large picture file in the preview window may specifically include:

Step A: According to the splicing rule of the large picture file, the large picture file is reversely split into multiple screenshots.

For example, when generating a large image file as a summary file, the server arranges P screenshots from left to right in chronological order from top to bottom into R rows and S columns, where R*S>=P, R, S, and P are all Is a positive integer, and then splicing the P screenshots of the arranged R rows and S columns into a large image file, then, in this step, the application client will reverse the downloaded large image file according to the splicing rule. Split into R rows and S columns for a total of P screenshots.

Step B: Set the play area of the preview window according to the size of the single screenshot.

Through the above settings, the size of the play area in the preview window is equal to the size of a single screenshot. That is, the length and width of the play area are equal to the length and width of a single screenshot.

Step C: Display the first screenshot in the play area.

Step D: Move the large picture file according to a predetermined movement rule every predetermined time interval T to display the next screenshot until the preview ends.

The above predetermined movement rule is determined by the splicing rule of the large picture file. As mentioned above, on the server side, when the server generates a large picture file, the server obtains a plurality of screenshots obtained by screen capture in a certain order. Then, in this step, the application client can move the large picture file in the reverse order of the above splicing. For example, if the server splicing multiple screenshots from left to right and from top to bottom in chronological order, then in this step, the application client can use the leftmost screenshot of the first row as the first image. Show and move the distance of the width of a single screenshot to the left to show the next screenshot until one line of the large image file is displayed. Then, the application client further moves the large picture file up to the height of the single screenshot, and moves the large picture file to the right to the leftmost one of the line to start the next line of the screenshot. Repeat the above steps until all screenshots of the large image file of the media content are displayed or the user chooses to stop previewing.

Further, if one media content corresponds to multiple digest files, the digest files are sequentially downloaded according to the generation order of the digest files, and the respective digest files of the media content are respectively displayed according to the above method. In the embodiment of the present application, the application client may send the request for storing the address of the digest file only once, and the server may feed back the storage address of all the digest files corresponding to one media content to the application client at one time. Alternatively, the application client may also send a request for the digest file storage address multiple times. For example, when the application client is about to preview a digest file, the server will request the storage address of the next digest file. At this point, the server will feed back the storage address of the next digest file to the application client according to the recorded interaction.

Figure 5 is an example of an automatic carousel large picture file. As shown in FIG. 5, the large picture file is saved by 100 screenshots and stitched together in a 10*10 manner, and the 100 screenshots are arranged in chronological order from left to right and top to bottom. In response to the user's preview request, according to the arrangement rule of the large picture file, the above large picture file is first split into 10 rows and 10 columns for a total of 100 screenshots, and the preview preview of the preview window is set according to the size of the single screenshot. The area is such that the size of the play preview area of the preview window is equal to the size of a single screenshot. When the preview is started, the first screenshot 501 is displayed in the preview window (the thick line screenshot is the currently displayed screenshot), and after waiting for the preset time interval T, the large picture file is moved to the left by the width 502 of the single screenshot, thereby Display a second screenshot 503 in the preview window (the thick line screenshot is the currently displayed screenshot, the dashed screenshot is the displayed screenshot), until the first line 504 of the large image file is displayed (the dotted screenshot is the displayed screenshot) . After that, move the large picture file up to the height 505 of the single screenshot, and move the large picture file to the right to a screenshot 506 on the far left of the line (the thick line screenshot is the currently displayed screenshot) to start the next line of screenshots. . The above process is repeated until all the screenshots of the large picture file corresponding to the media content are displayed.

In this way, by controlling the predetermined time interval T, it is possible to control the large picture file to move at a certain speed, thereby realizing the effect of video playback in the preview window.

Therefore, it can be seen that, in the process of searching for the target media content by the user, the user is provided with the media by setting a preview window for a certain candidate media content and playing the summary file of the media content in the preview window. More information than content information, it is convenient for the user to determine whether the candidate media content is the target media content that is needed by the user, to improve search efficiency, avoid unnecessary repeated searches, and save hardware resources and network resources on the terminal side and the network side. .

In addition, the above method of automatically rotating the summary file can control the size of each summary file by controlling the number of screenshots included in each large picture file and the resolution of each screenshot, for example, in general, a large The smaller the number of screenshots included in the image file and the lower the resolution of each screenshot, the smaller the file size; the larger the number of screenshots included in a large image file and the higher the resolution of each screenshot, the larger the file size. It is bigger. Therefore, the method of the present application can realize the controllable transmission of the media content while realizing the preview of the media content, that is, the quick preview of the media content can be realized under the lower traffic demand, thereby providing the user with a richer Information to improve the efficiency of media content search, thereby further saving hardware and network resources.

Based on the media content search process, the method for searching the media content may further include a process of adjusting the preview progress according to the user's playback progress adjustment operation, so as to preview the media content from each preview progress point desired by the user. aims. As shown in FIG. 2, the process of adjusting the preview progress may include:

Step 205: Acquire an operation position of the user currently in the preview window in response to the user's play progress adjustment operation.

In some examples of the present application, the playing progress adjustment operation may be an operation in which the user slides the cursor of the mouse to a certain position of the preview window. At this time, the determined operation position of the user in the preview window is the current mouse. The location of the cursor.

In other examples of the present application, the playing progress adjustment operation may be an operation of the user clicking a certain position of the preview window with a mouse or a finger, etc., at this time, the determined operation position of the user in the preview window is the user. The location clicked within the preview window.

In still another example of the present application, the playing progress adjustment operation may be an operation in which the user clicks on a certain position of the preview window with a mouse or a finger, and slides in the preview window. At this time, the determined user is currently in the preview window. The operation position is the position where the user clicks in the preview window and each position on the sliding track.

Step 206: Determine a play progress value of the media content corresponding to the operation location according to an operation position of the user currently in the preview window.

In the embodiment of the present application, the play progress value of the media content corresponding to the operation position may be determined according to the left and right border positions of the preview window in the horizontal direction according to the operation position, for example, according to the abscissa of the operation position. determine.

Specifically, it is not a general assumption that the preview window is a rectangle, and the abscissas of the left and right borders are respectively located at the pixels of W1 and W2, and the width of the preview window is W=W2-W1; When the user's operation falls within the preview window, for example, when the mouse is slid into the preview window or the user clicks on a certain position in the preview window, the abscissa x of the user's current operation position in the preview window is acquired, and is calculated. A play progress value T=(x-W1)/(W2-W1)*S corresponding to the operation position, where S is the duration of the media content.

Step 207: Determine, according to the play progress value, a location of the operation location corresponding to the screenshot of the media content in the digest file.

The application client can then start playing the digest file from the determined location.

In the embodiment of the present application, determining that the location of the screenshot corresponding to the media content in the digest file refers to determining a digest file where the screenshot is located and a specific location of the screenshot in the digest file, that is, determining the location The screenshot is in the first summary file and determines the screenshot in the first few rows and columns of the summary file.

In the present application, determining, according to the playback progress value, the digest file in which the operation location corresponds to the screenshot of the media content and the specific location of the digest file can be completed as follows: assuming that the server takes a screen capture of the media content The time interval is a, each summary file of the media content is composed of P screenshots, and each summary file is composed of R rows and S columns of screenshots, wherein R*S>=P, and the playback progress corresponding to the user's operation position If the value is T, the summary file of the screenshot corresponding to the operation position can be rounded down by the quotient of (T/a)/P, and the position of the screenshot in the summary file can be (T/a)/P. The remainder Y is obtained. For example, the quotient of Y/S is rounded down to get the number of rows in which the screenshot is located, and the remainder of Y/S is the number of columns in which the screenshot is located.

For example, the left side of the preview window has a horizontal coordinate of 0 pixels, and the right border has an abscissa of 100 pixels, that is, the width W of the preview window is 100 pixels, and the total duration of the media content selected by the user. It is 2000s, and the server takes a screen shot every 10s when generating the digest file, and gets 100 screen shots, and arranges each of the 100 screen shots in chronological order and splices into one large picture, and obtains 100 rows of 10 rows and 10 columns. Two large picture files stitched together in the screenshot. When the user's mouse slides into the position corresponding to the 75th pixel of the preview window, it can be determined that the playback progress value of the media content corresponding to the above location is (75-0)/(100-0)*2000s=1500s, That is to say, the playback progress corresponding to the 75th pixel position should be 1500s. Therefore, the playback progress of the 75th pixel position where the user's mouse position is located is 1500s, and the calculated 150/100 is rounded down to 1 and the remainder is 50, that is, the screenshot corresponding to the user's mouse position is the first summary. The 50th screenshot of the file. Further, based on the quotient and remainder of 50/10, it can be determined that the screenshot is located in the 5th row, the 10th column.

Thus, by the above method, when the user operates the mouse to cause the mouse cursor to fall to a certain position in the preview window or the user clicks on a certain position in the preview window, the preview for the media content can start from the screenshot corresponding to the position. . Moreover, when the user operates the mouse to move the cursor of the mouse within the preview window or the user's finger slides within the preview window, the above steps can be quickly completed according to the respective positions included in the movement trajectory, thereby realizing the effect of quickly previewing the media content. .

Correspondingly, in order to implement the playing of the summary file of the media content by the application client on the user terminal 11, the example of the present application further provides a media content searching method, which is applied to the server 13 side. The method is mainly used for performing at least one abstract file corresponding to the media content generated after the media content is uploaded, for example, in the process of encoding watermarking, by taking a screen shot of the media content and extracting a plurality of image frames. Thereafter, the server 13 receives a partial keyword input by the user sent by the application client, determines a corresponding text keyword according to the partial keyword, and then determines a corresponding one or more media content according to the text keyword; After the media content information of the one or more media content and the storage address of the digest file, the media content information of the one or more media content and the storage address of the digest file are sent to the application client on the user terminal 11 to perform the Show.

As mentioned above, the above summary file can be a large picture file or an animation file. Specifically, the server may intercept a plurality of screenshots from the media content according to a predetermined frequency, and generate a large picture file or an animation file by the intercepted screenshot, thereby generating one or more summary files of the media content. In order to control the size of the digest file, you can set the maximum number of screenshots included in the large image file or the animation file, so that there may be more than one digest file generated.

FIG. 6 is a flowchart of a media content searching method provided by an example of the present application. In the media content search method shown in FIG. 6, a large picture file is taken as an abstract file as an example for description. The method is performed by the server, as shown in Figure 6, and includes the following steps:

Step 601: Capture a plurality of screenshots from the media content according to a frequency of intercepting one frame of image from the media content at every predetermined time interval a.

Here, a is a preset step value of the extracted key frame, and according to experience a, it can generally take a value of 5-20 seconds, for example, 10 seconds.

Step 602: Combine each P screenshot according to a predetermined splicing rule to generate a large picture file, and use the generated at least one large picture file as one or more summary files of the media content.

Here, P is the number of key frames included in each digest file set in advance, and is a natural number. According to experience, P can generally take a value of 50-1000, for example 100, that is, each 100 screenshots are stitched and saved as a summary file. In addition, the predetermined splicing rule may specifically refer to arranging and splicing the extracted P screenshots in a matrix according to chronological order, for example, taking 100 screenshots in chronological order from left to right and from top to bottom in 10 rows. The 10 column matrix is stitched together and saved as a summary file.

Thus, in general, one media content will correspond to multiple digest files. For example, a movie is 120 minutes long, or 7200 seconds. If you extract a keyframe every 10 seconds according to the experience value, that is, cut a picture, and every 100 screenshots are put into a summary file, the movie should have 720. Screenshots, and the 720 screenshots should be saved in 8 summary files in sequence, with the first 7 digest files each containing 100 screenshots and the last summary file containing 20 screenshots.

For example, still taking FIG. 5 as an example, as shown in FIG. 5, the above-mentioned P screenshots are spliced and saved together in a 10*10 manner to form a summary file composed of 10 rows and 10 columns of screenshots. And the screenshot at the first column of the first row corresponds to a frame image at the beginning of the media content, and the screenshot at the 10th column of the 10th row corresponds to a frame image of the media content at the 1000th second.

Further, when intercepting the image of the media content, the model of the display device in the user may be referred to, that is, the display device of different sizes corresponding to different user terminals, and the size of the screenshot is adjusted, thereby capturing images of different sizes and generating corresponding sizes. A summary file of the screenshot. For example, user terminals of two sizes corresponding to resolutions of 1024*768 and 1280*960 can be screenshotd with different sizes to generate a summary file corresponding to the display device model of different user terminals.

Step 603: After the file name of the above summary file is spliced to the domain name of the content distribution network (cdn: content delivery network) according to a predetermined rule, the storage address of the summary file is generated.

In the embodiment of the present application, the URL of the generated digest file is directly spliced to the domain name of the CDN to obtain the URL of the digest file, so that the URLs of all the digest files of the media content, for example, https: //puui.qpic.cn/video_caps/0/m0024qjk1k9.q1.1.jpg/0.

Step 604: Receive a partial keyword input by the user sent by the application client, and determine a corresponding text keyword according to the partial keyword.

Step 605: Determine corresponding one or more media content according to the text keyword.

Step 606: Acquire the media content information of the one or more media content and the storage address of the digest file, and send the media content information of the one or more media content and the storage address of the digest file to the application client on the user terminal 11. End to make it display.

As described above, the server may feed back the storage address information of the corresponding digest file to the application client, or may request the storage address of the media content digest file when the application client requests the storage address of the media content digest file. The storage address of the media content summary file is fed back to the application client. Moreover, when there is more than one digest file corresponding to one media content, the storage address of all the digest files may be fed back at one time, or only the storage address of one digest file may be fed back at a time according to the request of the application client.

Through the above scheme, the application client can realize a quick preview of the key frame screenshot of the media content by rotating the large picture file by moving the image, and on the other hand, compared with the preview manner of the static poster, the impact effect is more A better experience, on the other hand, users can get more information to improve the accuracy of the user's search, avoiding repeated user operations and waste of resources. At the same time, compared with the media content, the summary file is very small, the time required for transmission and the occupied network resources are very small, thereby further avoiding waste of network resources.

Based on the system structure shown in FIG. 1 , the embodiment of the present application further provides a media content searching method, which is applicable to the server 13 , and may be based on a partial keyword input by the user and associated with the partial keyword. The media content determines a corresponding list of media content for the user to select.

FIG. 7 is a flowchart of a media content searching method provided by an embodiment of the present application. If the method is performed by a server, as shown in FIG. 7, the method includes the following steps:

Step 701: Receive a media content search request that carries a part of the keyword from the application client.

Here, the partial keyword may be the query content input by the user when searching for the target media content. For example, when the user wants to search for the media content "Speed and Passion 8", he may input part of the keyword "speed" as the query content, or input part of the keyword "passion" as the query content.

Step 702: Determine at least one text keyword according to the partial keyword.

Here, the above text keyword may be the name of the target media content. For example, the title "Speed and Passion 8" in the movie "Speed and Passion 8".

In some instances, server 13 typically maintains a library of candidate keywords to complete the search for media content. In this case, after receiving the partial keyword input by the user sent by the application client, the server 13 may perform fuzzy matching on the partial keyword and the candidate keyword in the candidate keyword library to obtain the highest matching degree. One or more text keywords. For example, when the user inputs a part of the keyword "three", a plurality of text keywords such as "Sansheng Sanshi Shili Peach Blossom", "New Three Kingdoms" and the like can be matched from the candidate keyword library.

Step 703: Sort the at least one text keyword according to the degree of association between the partial keyword recorded by the self and the at least one text keyword.

It can be understood that the above fuzzy matching method is likely to match a very large number of text keywords when some keywords input by the user do not have strong discrimination, and thus may drown out the name of the media content that the user really wants to search. Also taking the above example, when the user inputs the partial keyword "three", the server 13 may match a very large number of text keywords containing "three" from the candidate keyword library. The large number of search results returned based on these text keywords can make it difficult for users to quickly find the target media content "Sansei Sanshi Shili Peach Blossom" that they want to search.

As such, in some examples, the server 13 may pre-record the degree of association between the partial keywords and the text keywords. The degree of association between the partial keyword and the text keyword represents a probability statistic that the user inputs a partial keyword to search and finally selects a media content corresponding to a text keyword, such as the number of times selected or the number of times selected is the number of times of all searches. Proportion and so on. The higher the degree of association between a certain partial keyword and a certain text keyword, the greater the probability that the user finally selects the media content corresponding to the text keyword after inputting the partial keyword. In a specific implementation, one or more association counters may be set for some keywords, wherein each association counter is used to count the number of associations of the partial keywords with a certain text keyword to record the partial keywords and The relevance of a text keyword. At the beginning of the server 13 startup, there is usually no statistics for such data. Therefore, when the user inputs a certain partial keyword, the server 13 matches one or more text keywords from the candidate keyword library according to the partial keyword, and media content information of the media content corresponding to the text keywords. Provide the user with a choice. At this time, if the user selects one of the media contents, it indicates that the part of the keyword and the text keyword corresponding to the media content generate an association, so that the degree of association corresponding to the part of the keyword and the text keyword can be Adding 1 also adds 1 to the associated counter corresponding to the partial keyword and the text keyword (if there is no corresponding associated counter before the partial keyword and the text keyword, then a keyword and the partial keyword may be first established. The associated technology corresponding to the text keyword and its count value is set to 1). By such a method, when a large number of users search for media content and find the target media content that they want to search, each partial keyword will have a certain degree of relevance to the text keywords of one or more media content.

In this case, after receiving the partial keywords input by the user, the server 13 not only matches the candidate keyword library, but also further matches the partial keywords of the self-recording and the text keywords. The text keywords are sorted to rank the text keywords with high degree of relevance to the partial keywords, thereby ranking the media content that the user is more likely to select, so as to improve the search efficiency of the user.

For example, the current "Sansheng Sanshi Shili Peach Blossom" is a popular media content. After inputting some keywords "three", the most users will choose "Sansheng Sanshi Shili Peach Blossom". In this case, after The above correlation degree setting can get the highest degree of relevance between the partial keyword "three" and the text keyword "Sansheng Sanshi Shili Peach Blossom". Thus, when there is another user inputting part of the keyword "three", in addition to matching the text key In addition to the word "Sansheng Sanshi Shili Peach Blossom", you can also sort the relevance of some keywords "three" and each text keyword, so that the text keyword "Sansheng Sanshi Shili Peach Blossom" is placed in other text keywords. In the end, in the final search results returned to the user, the media content "Sansheng Sanshi Shili Peach Blossom" will be at the forefront.

In addition, if there are more text keywords matching some keywords, the top N text keywords with greater relevance may be retained according to the degree of association, where N is a preset value.

Step 704: Determine at least one media content corresponding to the at least one text keyword.

Since the text keyword may be the name of the target media content, the server 13 may determine a text content based on a text keyword and obtain media content information of the text content.

Step 705: Feed the media content information of the corresponding media content to the application client according to the sequence of the at least one text keyword.

In some embodiments, the media content information includes some or all of the information of the media content, the main actor, the poster, and the URL of the media content.

In some embodiments of the present application, the method may further include: updating a degree of association between the partial keyword and the text keyword according to a text keyword corresponding to the media content that the user finally selects to play. That is, for example, the value of the above-mentioned partial keyword and the associated counter corresponding to the text keyword is incremented by one.

In the method provided by the foregoing embodiment, by setting the degree of association between the partial keyword and the text keyword, and sorting the media content corresponding to the text keyword according to the degree of association, the effect of sorting the candidate media content according to the heat can be achieved. So that the information of the media content that is more likely to be selected by the user is displayed in front, thereby shortening the time for the user to search for the media content, improving the search efficiency of the user, and avoiding unnecessary page turning, searching, browsing, in the case of a large probability. And so on, thereby saving hardware resources and network resources on the network side and the terminal side.

Further, in some embodiments of the present application, the technical solutions of the foregoing two embodiments may also be combined, that is, the user is provided with a preview of the media content based on the ranking of the media content according to the degree of association. The function further shortens the time for the user to search for the media content, improves the search efficiency of the user, and further avoids unnecessary operations such as downloading and playing the media content, thereby further saving hardware resources and network resources on the network side and the terminal side.

In order to implement the above solution, as described above, the server 13 also needs to generate a digest file for each media content, and feed back the storage address of the media content to the application client while feeding back the media content information. In this way, after receiving the preview request of the user for a certain media content, the application client can download the summary file of the media content according to the storage address of the summary file, and play a quick preview of the media content by playing the summary file.

Specifically, as described above, the method for the server 13 to generate the media content summary file and the method for the application client 11 to browse the summary file have been described in detail in the foregoing, and are not described herein again.

Through the above scheme, on the one hand, by associating some keywords with the media content and accumulating the number of associations, the related media content is sorted, and the error and coverage caused by the matching of the pure text association and the media content name are avoided. problem. On the other hand, a quick preview of the key frame screenshots of the media content can be realized by playing the summary file, which has a more impact effect compared to the preview mode of the static poster, giving the user a better experience and enabling the user to obtain More information thus improves the accuracy of the user's determination of the search, avoiding the user's repeated operations and waste of resources.
