As shown in FIG. 8 , the controller 250 on the rotating TV can be provided with a vertical screen TV terminal APP and a horizontal screen TV terminal APP, wherein the vertical screen TV terminal APP can be activated when the rotating TV is converted to a vertical screen state, and is When the TV is rotated to maintain the vertical screen state, the application background of the resident controller 250 can generate the viewing history/favorite/click log after the user watches, favorites or clicks the vertical screen media asset, and sends the viewing history/favorite/click log To the server of the rotating TV; the horizontal screen TV terminal APP can be activated when the rotating TV is converted to the horizontal screen state, and is resident in the application background of the controller 250 when the rotating TV is kept in the horizontal screen state, and can be viewed, saved or clicked by the user. After the media assets are screened, a viewing history/favorite/click log is generated, and the viewing history/favorite/click log is sent to the server of the rotating TV.

In another embodiment, the functions of the vertical screen TV terminal APP and the horizontal screen TV terminal APP can also be realized by setting an APP or scheduling or service on the rotating TV. When the rotating TV is set with an APP or scheduling or service to realize the vertical screen TV terminal APP When the functions of the screen TV terminal APP and the horizontal screen TV terminal APP are used, the APP or scheduling or service can be set to have two working modes: horizontal screen mode and vertical screen mode. The working process is the same as that of the horizontal screen TV terminal APP. In the vertical screen mode, the working process of the APP or scheduling or service is the same as that of the vertical screen TV terminal APP. The APP can be configured so that the working mode is adapted to the current rotation state of the rotating TV.

The server of the rotating TV is provided with a terminal-oriented subsystem, a recommendation subsystem, a membership subsystem and a content subsystem. The terminal-oriented subsystem is set at the front end of the server and can interact with the display device 200 and the subsystems at the back end of the server. The recommendation subsystem, the membership subsystem and the content subsystem are all subsystems set at the back end of the server.

The terminal-oriented subsystem can receive the viewing history/collection/click log reported by the horizontal screen TV terminal APP, and generate the user's horizontal screen historical behavior according to the viewing history/collection/click log reported by the horizontal screen TV terminal APP; receive the vertical screen TV terminal APP The reported viewing history/favorites/click logs, according to the viewing history/favorites/click logs reported by the vertical screen TV terminal APP, generate the user's vertical screen historical behavior. The terminal-oriented subsystem sends the user's horizontal screen historical behavior and vertical screen historical behavior to the member subsystem.

The membership subsystem stores the user's horizontal screen historical behavior and vertical screen historical behavior in the database respectively.

The content subsystem can communicate with the media asset provider, capture media asset data of the media asset provider, store the media asset data in the content subsystem, and generate a media resource library. It should be noted that, in this embodiment, the media asset data refers to media asset information, such as a media asset cover, a media asset title, a media asset introduction, and a media asset playback volume.

The media asset data provided by the resource provider may be a media asset collection of the same product, and the media asset collection may include horizontal screen media asset data and vertical screen media asset data, wherein the horizontal screen media asset data is set with a horizontal screen flag bit, For example, H, to indicate that the media asset status of the media asset is a horizontal screen media asset, which corresponds to the horizontal screen status of the rotating TV; the vertical screen media asset data is set with a vertical screen flag bit, such as S, to indicate the media asset of the media asset. The asset state is the vertical screen media asset, which corresponds to the vertical screen state of the rotating TV. Of course, it is also possible to set only the vertical screen marker bit in the vertical screen media asset data, or only set the horizontal screen marker bit in the horizontal screen media asset data, as long as the horizontal screen media asset data and the vertical screen media asset data can be distinguished Open it.

The content subsystem can process the media asset data provided by the resource provider to manage the horizontal screen media asset data and the vertical screen media asset data in the media asset data. The processing process includes the following steps: splitting the media asset collection into a horizontal screen media asset data. A subset of screen media assets and multiple vertical screen media asset sets; set the horizontal screen media asset subset as the associated media asset data of each vertical screen media asset set.

As shown in Figure 9, a media asset collection provided by a resource provider includes the following media asset data: horizontal screen single episode of media assets-movie A, media asset horizontal screen single episode-movie B, media asset horizontal screen single episode-trailer C. Media assets horizontal screen single episode-trailer D, media asset horizontal screen single episode-feature E, media asset vertical screen single episode-film F, media asset vertical screen single episode-movie G and media asset vertical screen single episode- Trailer H. After the content subsystem captures and decomposes the media asset collection, it obtains a horizontal-screen media asset subset AA and multiple vertical-screen media asset collections, wherein the horizontal-screen media asset subset AA includes media asset horizontal-screen single-episode-Pianhua A. Horizontal screen single episode of media assets-movie B, media asset horizontal screen single episode-trailer C, media asset horizontal screen single episode-trailer D, media asset horizontal screen single episode-feature E; vertical screen media asset episode For: vertical screen media asset episode BB: media asset vertical screen single episode-Pianhua F, vertical screen media asset episode CC: media asset vertical screen episode-Pianhua G and vertical screen media asset episode DD: media asset vertical screen Single Episode - Trailer H. The vertical screen media asset set BB, the vertical screen media asset set CC, and the vertical screen media asset set DD are respectively associated with the horizontal screen media asset subset AA, and the associated horizontal screen media asset subset is called each The associated media asset data of the vertical screen media asset set. The association relationship may be an association list, and by searching for the association relationship, a subset of horizontal screen media assets associated with a single vertical screen episode of any media asset can be obtained.

When entering the vertical screen homepage, the vertical screen TV terminal APP will generate a media asset recommendation request including the current rotation state of the display device to obtain the vertical screen homepage data. At this time, the media asset recommendation request can be called the vertical screen homepage request, and the vertical screen The homepage request can include a homepage layout request and a media asset data request. The data requested by the homepage layout request includes the homepage layout data used to draw the homepage in a vertical screen, such as the type of columns set on the homepage in a vertical screen, and the number of recommended positions set for each column. The data requested by the media asset data request may include the media asset data displayed on the recommendation position on the home page of the vertical screen, depending on the type of media assets supported by the recommendation position, etc.

The vertical screen TV terminal APP sends the vertical screen homepage request to the terminal-oriented subsystem, and the terminal-oriented subsystem obtains the homepage arrangement data corresponding to the rotation state identifier according to the vertical screen homepage request, and sends a media resource recommendation request to the recommendation subsystem to obtain media resources. resource recommendation data.

The recommendation subsystem obtains the user's horizontal screen historical behavior and vertical screen historical behavior from the member subsystem according to the rotation status identifier, and obtains vertical screen media asset data from the content subsystem, and combines the user's horizontal screen historical behavior, vertical screen historical behavior and vertical screen. The media asset data obtains the media asset recommendation data corresponding to the vertical screen state, and sends the media asset recommendation data to the terminal-oriented subsystem; or, the recommendation subsystem only obtains the media asset based on the user's vertical screen historical behavior and vertical screen media asset data recommendation data; or, the recommendation subsystem further obtains media asset recommendation data by combining the user historical behaviors of other users. Facing the terminal subsystem, it sends the media resource recommendation data and the homepage arrangement data to the vertical screen TV terminal APP. The vertical screen TV terminal APP draws the vertical screen homepage according to the media resource recommendation data and the homepage arrangement data, and presents the media resources to the user on the vertical screen homepage. Recommended data. Of course, the vertical screen TV terminal APP can also locally store the homepage layout data in the vertical screen state on the rotating TV. In this way, when sending a vertical screen homepage request, it only needs to send a media asset recommendation request, and then according to the received media asset recommendation data and The home page layout data in the vertical screen state is stored locally to draw the vertical screen home page.

For the recommendation of media assets on the horizontal screen homepage, please refer to the media asset recommendation on the vertical screen homepage, which will not be repeated here.

In order to further describe the media asset recommendation method of the rotating TV, the present embodiment provides a media asset recommendation method in the second aspect, as shown in FIG. 10 , the method includes the following steps:

Step S110: When the recommendation request is triggered, send a media asset recommendation request including the current rotation state of the display device to the server.

The horizontal screen TV terminal APP of the rotating TV terminal will trigger a media resource recommendation request after rotating the TV to enter the horizontal screen homepage, or after the vertical screen TV terminal APP rotates the TV to enter the vertical screen homepage, the media asset recommendation request will include the current rotation state of the display device. It is sent to the terminal-oriented subsystem in the rotary TV server, and the terminal-oriented subsystem sends a media asset recommendation request to the recommendation subsystem.

The media asset recommendation request is configured to: enable the server to determine media asset recommendation data according to the current rotation state, and media asset recommendation data corresponding to different current rotation states are different.

Step S120: Receive media asset recommendation data corresponding to the current rotation state from the server.

As shown in FIG. 11 , a method for the recommendation subsystem of the server to calculate the media asset recommendation data may include steps S210-S250.

Step S210: Perform media asset content analysis on the user's historical vertical screen behavior and horizontal screen historical behavior according to a first preset weight, where the first preset weight is determined according to the current rotation state of the display device, to obtain a user behavior label.

The first preset weight includes the weight of the historical behavior of the horizontal screen and the weight of the historical behavior of the vertical screen. The weight of historical behavior refers to the proportion of vertical screen historical behavior in the user historical behavior to be analyzed for content.

The recommendation subsystem can set two first preset weights, corresponding to the two rotation states of the rotating TV, wherein, when the current rotation state of the rotating TV is the portrait state, the first preset weight can be set to the landscape history behavior The weight of the historical behavior of the vertical screen is lower than the weight of the historical behavior of the vertical screen. For example, the weight of the historical behavior of the vertical screen is 80%, and the weight of the historical behavior of the horizontal screen is 20%; when the current rotation state of the rotating TV is the horizontal screen state, the first preset weight It can be set that the weight of the historical behavior in the horizontal screen is higher than the weight of the historical behavior in the vertical screen. For example, the weight of the historical behavior in the horizontal screen is 80%, and the weight of the historical behavior in the vertical screen is 20%.

In some embodiments, the historical behavior weight corresponding to the current rotation state is 100%, and the historical behavior weight corresponding to another rotation state is 0.

For example, when a rotating TV, such as TV A, sends a media asset recommendation request that includes the current rotation state of TV A being the vertical screen state to the server of the rotating TV, the recommendation subsystem obtains the user historical behavior corresponding to TV A from the membership subsystem, The obtained user historical behavior includes historical behavior in horizontal screen and historical behavior in vertical screen. According to the historical behavior in horizontal screen, the total number of historical media assets data in horizontal screen that the user has watched and saved is m. The total number of vertical screen historical media data that has been viewed and saved is n. According to the weight of the historical behavior of the horizontal screen in the vertical screen state is 20%, the weight of the historical behavior of the vertical screen is 80%, and the historical media data of the horizontal screen and the historical media of the vertical screen are extracted according to the ratio of 20%: 80%. resource data, obtain a first quantity x of horizontal screen historical media asset data and a second quantity y of vertical screen historical media asset data, where y=x*(80%/20%), x=n*(20%/ 80%).

By performing content analysis on the above-mentioned horizontal screen historical media asset data and vertical screen historical media asset data, media asset content labels, such as education, pets, funny, etc., can be obtained. In one embodiment, the resource provider can set content tags in the media asset data when providing the media asset data, and the recommendation subsystem can extract the content tags during content analysis; in another embodiment, the resource provider The media asset data provided by the provider does not contain content tags. The recommendation subsystem can analyze the horizontal screen media asset data and the vertical screen media asset data according to the preset content analysis algorithm to obtain the content tags. The content analysis algorithm can be implemented based on the existing technology. , and will not be described in detail in this application.

The recommendation subsystem aggregates the content tags of the horizontal screen media asset data and the content tags of the vertical screen media asset data to obtain the user behavior tags.

Step S220: Filter out user recommendation data that is suitable for the rotation state from the media resource library according to the user behavior tag.

When the media asset recommendation request is a vertical screen homepage request, each vertical screen media asset list set in the media resource library whose content tag is consistent with the user behavior tag is used as the user recommendation data.

When the media asset recommendation request is a horizontal-screen homepage request, each horizontal-screen media asset subset whose content label is consistent with the user behavior label in the media resource library is used as user recommendation data.

Step S230: Obtain collaborative recommendation data through a collaborative filtering algorithm.

In some embodiments, the user recommendation data obtained in step 220 may be recommended to the user as media asset recommendation data, or step S230 may be continued to implement a more refined recommendation.

The recommendation subsystem can obtain the user historical behaviors of different users from the membership subsystem, and obtain other users whose historical behaviors are similar to the users of TV A exceeding the preset threshold, which are recorded as collaborative users, and obtain the historical media asset data of the collaborative users. The historical media asset data that is the same as that of the user of TV A is filtered out from the user's historical media asset data to obtain collaborative recommendation data. Among them, the preset threshold can be set to 80%, which can be dynamically adjusted according to the user quantity level of the membership subsystem and the similarity of the user's historical behavior. The preset threshold value can be increased to provide users of TV A with more accurate collaboratively recommended media resources, or the preset threshold can be adjusted lower according to the low level of users and the low similarity of users’ historical behavior, so as to provide more accurate media resources for TV A’s users. Users can provide more diverse collaboratively recommended media assets, and the preset threshold can also be adjusted according to other actual situations.

Step S240: Screen out the media asset data to be recommended from the candidate media asset data, wherein the alternative media asset data includes user recommendation data and collaborative media asset data, and the weight between the user recommendation data and the collaborative media asset data is the second. Preset weights.

The user recommendation data and the collaborative recommendation data are sorted in chronological order respectively, and a certain number of the latest user recommendation data and the latest collaborative media asset data are selected according to the second preset weight as the media asset data to be recommended. The recommendation subsystem may set the second preset weight so that the proportion of user recommendation data is higher than that of collaborative recommendation data, for example, the proportion of user recommendation data is 80%, and the second preset weight can also be adjusted according to the actual situation.

Further, if the amount of media asset data to be recommended that is screened out according to the user recommendation data and collaborative recommendation data is small, the media asset data that the total playback volume in the media resource library meets the preset playback volume threshold and is adapted to the rotation state can be determined. It is added to the data of the media assets to be recommended, wherein the play volume threshold can be set according to the actual situation.

Step S250: Generate media asset recommendation data according to the media asset data to be recommended.

When determining the recommendation order of the media asset data to be recommended, the recommendation subsystem can sort it according to the total playback volume and the user's historical behavior associated with the media asset data to be recommended. sort. The priority can be divided into: the first priority, the second priority and the third priority, wherein the media asset data of the first priority to be recommended may be obtained according to the user's historical behavior in the media asset data to be recommended. User recommendation data and collaborative recommendation data that the user has not watched, the remaining user recommendation data and the remaining collaborative recommendation data in the media asset data to be recommended with the second priority, and the media asset data to be recommended with the third priority. Media asset data other than user recommendation data and collaborative recommendation data in the data. The media asset data to be recommended is sorted in descending order of priority, wherein the media asset data of the same priority can be sorted in reverse order according to the total playback volume.

After arranging the media asset data to be recommended according to the above sorting method, the media asset recommendation data is obtained. The recommendation subsystem sends the media asset recommendation data to the vertical screen TV terminal APP.

In addition to the method for calculating the media asset recommendation data shown in FIG. 11 , the media asset recommendation data may also be calculated by other methods. Still taking the current rotation state as the vertical screen state as an example, after the user recommendation data is obtained in step S220, the user recommendation data can be used as the media asset data to be recommended, and then step S250 is performed to generate media asset recommendation data; When collecting data, the user behavior label can also be obtained only according to the user's vertical screen historical behavior, and then the user recommendation data can be obtained; in addition, there are other methods, which are not listed one by one in this embodiment.

Step S130: Control the display to display the media asset recommendation data.
