In some embodiments, the server of the display device may analyze a plurality of media asset viewing records of the same user id over a period of time, and the analysis method includes: and acquiring a media asset id in the media asset watching record and a media asset poster in the media asset watching record, and acquiring a tag of the media asset poster according to the media asset id.

In some embodiments, a server of the display device may count tags of media asset posters corresponding to multiple media asset viewing records of the same user id over a period of time, and generate a first tag group including multiple poster preference notes by using tags with relatively high frequency as poster preference tags of the user. For example, the poster preference tag may include a warm tone, a text center. Each poster of the asset may be provided with a second set of tags, which may include all tags of that poster.

In some embodiments, weights may also be set for tags in the first tag group according to the tag type. Illustratively, the weights may be set according to the frequency with which the tags appear in the asset viewing record.

In some embodiments, the server of the display device may count tags of multiple pieces of media asset viewing records of the same user id within a period of time, and generate a tag group including multiple media asset preference notes by using the tags whose occurrence frequency exceeds a threshold as media asset preference tags of the user. Illustratively, the media asset preference tag may include a modern, actor XX.

In some embodiments, the user's poster preference tags and asset preference tags may be stored as user data in a user database in a server.

In some embodiments, the server of the display device may recommend a personalized poster for each asset to the user after obtaining the user's poster preference tags and the poster tags for the asset.

In some embodiments, a method for a server of a display device to recommend a personalized poster for a user may be seen in fig. 10, which is a timing diagram of poster distribution according to some embodiments.

As shown in fig. 10, the server of the display device may further include a terminal-oriented subsystem. The terminal-oriented subsystem may interact with the terminal, i.e., the television, and interact with other servers to generate data back to the terminal.

In some embodiments, after the user enters the interface of the video-on-demand program shown in fig. 5 or another media asset recommendation scenario, the display device may send a media asset recommendation request to the terminal-oriented subsystem, where the media asset recommendation request may include a user id of the display device currently logged in, terminal information, and interface information, where the terminal information may include hardware information and software information of the terminal, the hardware information may include a model of a television, the software information may include a software version of the video-on-demand program, and the interface information may include identification information of a current interface of the terminal.

In some embodiments, after receiving the media asset recommendation request, the terminal-oriented subsystem may extract the user id, the terminal information, and the interface information from the media asset recommendation request, and screen a target media asset to be recommended to the user from the media asset library according to a preset media asset recommendation rule. Illustratively, one preset media asset recommendation rule is to select, according to a media asset preference tag of a user, a media asset whose tag is consistent with the media asset preference tag from a media asset library as a target media asset.

In some embodiments, the terminal-oriented subsystem may search the user database for the poster preference tag corresponding to the user id according to the user id extracted from the media asset recommendation request.

In some embodiments, after obtaining the target medium, the terminal-oriented subsystem may match the first tag group of the user with tags of posters of the target medium, calculate the number of tags of the poster preference tags of the user and tags of each poster, and use the number of tag coincidences as a matching degree. And taking the poster with the maximum matching degree, namely the number of superposed labels, as the target poster of the target medium. After obtaining the target poster of the target media asset, the terminal-oriented subsystem can generate recommendation data of the target media asset, wherein the media asset recommendation data can comprise a plurality of pieces of media asset data of the target media asset, and the media asset data can comprise data such as the poster, the title, the media asset ID and the like.

In some embodiments, after obtaining the target asset, the terminal-oriented subsystem may match the first tag group of the user with tags of posters of the target asset, calculate the number of tags overlapping the poster preference tag of the user with the tag of each poster, calculate the weight of the overlapping tags in the first tag group, and use the product of the number of overlapping tags and the weight thereof as the matching degree of the first tag group and the second tag group. And taking the poster with the maximum matching degree as a target poster of the target medium. After obtaining the target poster of the target media asset, the terminal-oriented subsystem can generate media asset recommendation data of the target media asset, wherein the media asset recommendation data can comprise a plurality of pieces of media asset data of the target media asset, and the media asset data can comprise data such as the poster, a title, a media asset ID and the like.

For example, if the weight of the actor a tag is the greatest in the first tag group, the actor a tag may be searched for in a second tag group of the posters of the target asset, and the poster containing the tag may be used as the target poster of the target asset, and if there are multiple posters containing the actor a tag, a target poster may be determined according to the matching of the other tags of the first tag group and the tags of the second tag group; if the weight of the comedy label is the largest in the first label group, searching the comedy label in the second label group of each poster of the target medium asset, and taking the poster containing the label as the target poster of the target medium asset; if the weight of the main information centered tag is the largest in the first tag group compared with the other main information position tags, the poster in which the main information centered tag is included in the second tag group can be selected as the target poster.

In some embodiments, the terminal-oriented subsystem may generate interface data of a media asset recommendation page according to recommendation data of a plurality of target media assets and arrangement data of the media asset recommendation page corresponding to the media asset recommendation request, and then transmit the interface data of the media asset recommendation page to the display device, where the arrangement data may be determined according to terminal information and interface information in the media asset recommendation request, and includes parameters such as size, dimension, position layout, and the like of a media asset control.

In some embodiments, after receiving the interface data of the media asset recommendation page sent to the terminal subsystem, the display device may generate and display the media asset recommendation page shown in fig. 5, where a plurality of target posters of target media assets may be displayed on the media asset recommendation page. In fig. 5, asset 1, asset 2, … …, and asset 10 are all target assets screened by the terminal-oriented subsystem according to the user's asset preference tag.

As can be seen from the above embodiments, in the embodiments of the present application, a first tag group is set for each user in advance, a plurality of posters are set for each asset, and each poster is provided with a second tag group, so that after a user enters a asset recommendation page and a target asset is determined, a poster of the target asset can be screened out according to the matching degree of the first tag group and the second tag group, and is determined to be a target poster to be displayed to the user, and then data containing the target poster is sent to a terminal, so that the terminal displays the target poster. Because the target poster is obtained according to the first tag group of the user, the probability that the target poster is loved by the user is higher, the interest of the user in watching the target media asset is promoted, and the media asset popularization is promoted.
