The power supply 290 may be a built-in power supply circuit installed inside the display apparatus 200 or may be a power supply installed outside the display apparatus 200.
After the user starts the display device 200, he starts to watch channels, such as movies, tv, art, news, etc., in the channel bar (Tab bar), and after entering any channel, he continues to search for the desired media content. However, the user may often find out what he or she wants to watch over a long time, and based on this, the display device 200 provided in the embodiment of the present application is capable of performing content recommendation for the user, and the controller 250 in the display device 200 is configured to perform a content recommendation process and present the recommended content on the display 275. The content recommendation process provided by the embodiment of the present application is explained below with reference to the drawings.
Referring to fig. 5, a flowchart of a content recommendation method according to an embodiment of the present invention is shown. As shown in fig. 5, the method comprises the steps of:
s501: the length of time that the focus stays on the user interface is monitored.
When a user turns to a certain channel, the user always turns up and down to watch each media asset on the channel, namely, the user always stays on the current user interface and does not click the operation of playing the media assets all the time. For example, a user clicks into the "movies" channel, always turning down the individual movies on that channel, but never playing any movie. In this case, content recommendation needs to be performed for the user.
In some embodiments of the present application, before monitoring the length of time that the user interface remains focused on, the controller 250 may also determine whether the display device 275 is enabled for the recommended function. Referring to fig. 6, a schematic view of an interface for setting a function of recommending content according to an embodiment of the present invention. Referring to fig. 6, the user can open the recommendation function through "set" on the upper right corner of the display 275, and correspondingly pop up a "if you cannot find the favorite content, turn on an AI watch at will" prompt box, where "AI watch at will" is the recommended content. When a prompt box for confirmation pops up, the user can enter an opening area through 'down', 'up', 'left' or 'right', and then click a 'confirmation' key to start the recommendation function. Of course, the user may also select the recommendation function by a voice control command, for example, by sending an "on" voice. Instead, the recommendation function is turned off by selecting "not on".
In one implementation, if the display device 200 turns off the recommendation function, the operation rule acquisition request is not sent to the server 300, and if the display device 200 turns on the recommendation function, the operation rule acquisition request is sent to the server 300, and the operation rule acquired according to the operation rule acquisition request is received from the server 300.
In the application, if the operation rule indicates an alternative user interface for executing content recommendation, the indication information of the alternative user interface is displayed. The alternative user interfaces may be individual channels in a channel bar. The server 300 refers to each channel in the channel column by indication information corresponding to the alternative user interface, for example, by a channel name, a channel fixed number, or a thumbnail of the corresponding interface, or the like.
Referring to fig. 7, an interface diagram for selecting a selected interface is provided according to an embodiment of the present invention. In fig. 7, the various alternative user interfaces are referred to by channel name. And determining that the selected interface is selected from the alternative user interfaces corresponding to the indication information for receiving the selection operation according to the selection operation input to the indication information, namely, the user can select the selected interface from the alternative user interfaces by clicking any one or more channel names.
That is, the selected interface selected by the user is the user interface that needs to be recommended. Therefore, when the focus dwell interface is the selected interface, the length of time that focus is dwell on the user interface is monitored to send a recommended content acquisition request to the server 300. When the focus dwell interface is not the selection boundary, the length of time that focus remains on the user interface is not monitored to avoid sending a recommended content acquisition request to the server 300.
In the above, the user sets whether to start the recommendation function through the display device 200 according to the user's own use requirement.
Of course, some display devices 200 need to request the server 300 to check whether or not they have the recommendation function for reasons such as different models or whether or not they support the local area, and the following description will be made specifically.
The embodiment of the present application further provides another display device, in which the controller 250 needs to request the server 300 for an operation rule of the display device 200, where the operation rule is used to instruct the display device 200 to start a recommendation function. That is, the display apparatus 200 acquires its own operation rule in which whether or not the display apparatus 200 has the recommendation function, through the server 300. Some display devices support the recommendation function and some display devices do not support the recommendation function for different television models, different regions and the like.
When receiving the operation rule acquisition request from the controller 250, the server 300 queries the operation rule corresponding to the display apparatus 200 according to at least one of information such as an ID (Identity document) of the display apparatus 200 or an account, and issues the operation rule to the display apparatus 200.
According to the indication of the operation rule, if the display device 200 does not have the recommendation function, the time length of the user staying on the user interface is not counted. If the display device 200 has the recommendation function, the duration of the focus staying on the user interface is monitored. In one implementation, the timer is started as soon as the user switches into a channel.
In the embodiment of the present application, the operation rule further indicates a selected interface for performing content recommendation. Only under the selected interface, the server 300 may recommend the media asset to the display device 200. That is, the server 300 specifies in the operation rules under which channels content recommendations are made to the user.
Therefore, only when the focus stays on any selected boundary surface, the time length of the focus staying on the user interface is monitored to send a recommended content acquisition request to the server 300. Correspondingly, when the focus stays in other user interfaces that do not need to recommend content, the browsing duration is not timed, so as to avoid sending a request for acquiring recommended content to the server 300.
In the above, for the controller 250, the operation rule is obtained through the server 300, and whether the content recommendation function is provided is checked through the operation rule, and after the recommendation function is confirmed, the time length of the focus staying on the selected interface is counted.
S502: and when the browsing duration of the focus under the user interface is longer than the preset browsing duration, sending a recommended content acquisition request to a server.
In the embodiment of the application, the operation rule further includes a preset browsing duration. In the application, the first user interface position display displays an interface corresponding to the first channel control at the focus position, and the time length during which the focus moves in the first user interface and the input confirmation instruction is not received can be regarded as the browsing time length. If the preset browsing duration is X minutes, when the browsing duration of the user in a user interface exceeds X minutes, that is, within X minutes, the user always turns over the content in a certain channel and does not click to play, the controller 250 sends a recommended content acquisition request to the server 300.
The timing of the browsing duration of the current user interface may be stopped after the controller 250 sends out the recommended content acquisition request. And if the browsing time of the user in any user interface is less than or equal to the preset browsing time, namely, the user selects the content to be watched in x minutes and clicks and plays, ignoring the current browsing timing. Or, in x minutes, the user performs channel switching, and turns over to watch in the "movie" channel and watches in the "tv play" channel, which means that the user searches for the content he wants to watch, and at this time, the user does not need to perform browsing timing.
S503: and receiving the recommended content sent by the server according to the recommended content acquisition request.
The server 300 receives the recommended content acquisition request from the controller 250, acquires the recommended content matching the display apparatus 200 according to the recommended content acquisition request, and transmits the recommended content to the display apparatus 200.
When the display device 200 receives the recommended content, a prompt is presented to the user. Referring to fig. 8, a schematic diagram of a server sending recommended content to a display device according to an embodiment of the present invention is provided. In fig. 8, the server 300 pops up a prompt box on the display 275 when sending the recommended content, and determines whether the user needs to accept the recommended content in the form of the prompt box. For example, in fig. 8, the content of the prompt box may be "whether you cannot find favorite content, and recommend AI at will for you", where "AI at will" is the recommended content. If the user receives the recommended content, "watching immediately" may be selected, and if the user does not receive the recommended content, "calculating" may be selected. If the user is prompted to display, the browsing timing can be stopped.
If the display device 200 does not receive the recommended content, no prompt is displayed to the user, and the browsing timing is stopped. Here, the recommended content recommended by the server 300 is not received, and may be an abnormal situation such as a network disconnection or a server disconnection.
S504: controlling the display to present the recommended content.
In the embodiment of the present application, after the user receives the recommended content, the display 275 is controlled to display the recommended content. In one implementation, the user may press a certain button through a remote controller, for example, in fig. 8, when a prompt box for confirmation is popped up, the user receives the recommended content recommended by the server 300 by "down", "up", "left", or "right" entering a "lima watch" area, and then clicking the "confirmation" button. Of course, the user may also select the recommended content by a voice control command, for example, by sending a "standing horse watching" voice, the user receives the recommended content recommended by the server 300. Or, a preset time period may be set, and the recommended content recommended by the server 300 is received by default if the user does not perform an operation within the preset time period, where the preset time period may be 10 seconds or 20 seconds.
When the user receives the recommended content, the display device 200 receives the recommended content recommended by the server 300 and displays the recommended content on the display 275.
Of course, the user may also choose not to accept the recommended content, for example, the user may press a button on a remote controller or send a voice command, etc., and choose "count" in the prompt box. If the user does not accept the recommended content, the controller 250 dismisses the prompt box and controls the display 275 to continue displaying the user interface currently viewed by the user. In addition, if the user refuses to receive the recommended content in the user interface, which means that the user does not need to recommend the content by the server 300 in the user interface at this time, the recommending function may be stopped if the user still browses in the user interface.
Regarding the recommended content recommended by the server 300, in this embodiment of the application, when the recommended content is an audio/video data string or an audio/video address sent by the server 300, if the user receives the recommended content, the display device 200 automatically accesses the server 300 to obtain audio/video according to the audio/video data string or the audio/video address, and the controller 250 controls the display 275 to directly play the audio/video.
Fig. 9 is a schematic diagram of recommended content provided in an embodiment of the present invention. In conjunction with fig. 8 and 9, when the user receives "AI watch at will" in the "tv drama" channel in fig. 8, the user can switch to the interface in fig. 9 accordingly. In fig. 9, the leftmost column is an "AI recommendation bar" for indicating that the user is currently in AI-casual view. The middle column is a 'recommendation list', and the user can select the media asset content to be watched through the recommendation list. Of course, in the recommendation list, the favorite assets of the user statistically recommended according to the viewing behavior of the user, for example, the user may like to view "standing mood" under a "tv drama" channel. In the recommendation list, there are also media assets according to the current hot-cast, such as "NBA live", and the like. The rightmost side is a video preview box, and the media assets under the corresponding recommendation list, such as the first set of the display sentiments which are being played, are played in the video preview box.
In fig. 9, after the user receives the "AI watch at will", a certain set of the story line is automatically played through the "video preview box". Of course, which episode is specifically played may be determined by the user himself or herself, see fig. 10, which is a schematic diagram of another recommended content provided by the embodiment of the present invention. In conjunction with fig. 10, the recommended content further includes an episode list of the audios and videos, and the detail page corresponding to the audios and videos is arranged and displayed at the lowest part in the "video preview box". The user may control the display 275 to play any episode of the audio/video according to his viewing needs.
Regarding the recommended content recommended by the server 300, in some embodiments, after the audio/video data string or the audio/video address sent by the server 300, if the user receives the recommended content, only the search interface may be displayed, and the recommended content is not played. For example, the server 300 recommends a plurality of audiovisual contents to the display device 300, and the display device 200 may only display the plurality of audiovisual contents in an arrangement in a "video preview frame", and at this time, the plurality of audiovisual contents are not played first. After the user selects any audio/video, the display device 200 accesses the server 300 according to the corresponding audio/video address to acquire the audio/video for playing.
This is the content recommendation process in the display device 200. When the user cannot search the desired media assets in the late stage, the display device 200 can recommend the user, and play the recommended content on the premise of obtaining the user's consent, so as to improve the viewing experience of the user.
Embodiments of the present application also provide another display device in which a controller is configured to perform a content recommendation process. The content recommendation process of the controller is specifically described below with reference to the drawings.
Referring to fig. 11, a flowchart of another content recommendation method according to an embodiment of the present invention is shown. Referring to fig. 11, the controller 250 is configured to perform a content recommendation process including the steps of:
s1101: and controlling the display to display a first user interface corresponding to the first channel control at the focus position.
When the user starts the display device 200, the controller 250 in the display device 200 monitors the operation behavior of the user. The method includes controlling a display to display a first user interface corresponding to a first channel control at a focus position.
S1102: and if the focus moves in the first user interface and the browsing duration without receiving the input confirmation instruction is longer than the preset browsing duration, controlling a display to display a recommended content interface.
In the first user interface, within a certain preset time, if the focus is only moved and an input confirmation instruction is not received, the display can be controlled to display the recommended content interface. That is, the controller 250 sends a recommended content acquisition request to the server 300, and the server 300 searches for corresponding recommended content according to the recommended content acquisition request and transmits the recommended content to the display device 200. The controller 250 receives the recommended content and presents a recommended content interface to play the recommended content on the recommended content interface according to the received recommended content.
Further, a screen locking duration is preset in the application, and the screen locking duration is the duration that the focus moves in the first user interface. And if the screen locking duration that the focus does not move in the first user interface is longer than the preset screen locking duration, controlling the display to display a screen locking picture. The screen locking operation is actually executed as follows: the focus remains stationary for a period of time, without any input, or even without any playback process, and the display 275 is locked.
In some embodiments, the content for display in the recommended content interface includes different audiovisual content corresponding to a plurality of channel information. When the controller 250 controls the display 275 to display the recommended content interface, the first audio/video content corresponding to the first channel information is determined according to the first channel information corresponding to the first channel control before the recommended content interface is displayed, and the display 275 is controlled to display the first audio/video content on the recommended content interface.
The server 300 sorts and outputs a recommended content in the entire asset database, and then issues the recommended content to the display device 200 for playing. Further, when sorting the recommended content, the recommended content is filtered. All the media assets in the media asset database have corresponding channel information, and the attributes of the media assets are represented by the channel information. For example, for "Chen-qing-ling", channel information such as a TV show and an ancient costume is identified. According to the method and the device, the movie and television type media assets can be recommended under the movie and television channel, the education type media assets are recommended under the education channel, and when the recommended content is obtained, the corresponding type of media assets are searched from the media asset database according to the corresponding channel information.
S1103: and if the input confirmation instruction is received within the preset browsing duration, controlling the display to display a second user interface corresponding to the control at the position of the focus when the confirmation instruction is input.
And in the first user interface, if an input confirmation instruction is received within a certain preset time length, controlling a display to display a second user interface corresponding to the control at the position of the focus when the input confirmation instruction is input. That is, a jump occurs in the first user interface, and a switch is made to the second user interface according to a selection operation by the user.
In some embodiments, after the display displays the second user interface, if the second user interface is an interface corresponding to the second channel control, the browsing duration corresponding to the focus is monitored again so that the browsing duration during which the focus moves in the second user interface and the input confirmation instruction is not received is greater than the preset browsing duration, and the display is controlled to display the recommended content interface. On the contrary, if the second user interface is not the interface corresponding to the second channel control, the browsing duration corresponding to the focus is not monitored. The second channel control is a control which is functionally parallel to the first channel control and is used for displaying media resources with different channel attributes. That is, only when the focus is on the user interface corresponding to the channel control, the browsing duration corresponding to the focus is monitored again.
In some embodiments, after the second user interface is displayed on the display, if the second user interface is a window where a video is played, the browsing duration corresponding to the focus is not monitored. If the second user interface does not have a window for playing the video, monitoring the browsing duration corresponding to the focus again so that the browsing duration when the focus moves in the second user interface and the input confirmation instruction is not received is longer than the preset browsing duration, and controlling a display to display a recommended content interface. That is, only if the second user interface does not include the details of the playing window or the full-screen playing page, the browsing duration corresponding to the focus is monitored again.
To further describe the content recommendation process, an embodiment of the present application further provides a server, and fig. 12 is a flowchart of a method for configuring a server according to an embodiment of the present invention. With reference to fig. 12, the configuration process of the server includes the following steps:
s1201: receiving a recommended content acquisition request from a display device, wherein the recommended content acquisition request comprises a user identifier and a channel identifier.
In the embodiment of the present application, the display device 200 transmits a recommended content acquisition request to the server 300, and the server 300 receives the recommended content acquisition request. The recommended content obtaining request includes a user identifier and a channel identifier, where the user identifier is a user ID, and according to the user ID, the server 300 can specify to which user the recommendation needs to be made, and according to the channel identifier, the server 300 can specify in which channel in the channel bar the user is currently located.
In one implementation, the recommended content of the server 300 is different when different users browse the same channel, i.e., when both user a and user B browse the series channel. When the same user browses different channels, that is, when the user a browses a drama channel and a news channel, the contents recommended by the server 300 are different. For example, under a tv show channel, content of a tv show is recommended for the user, and under an education channel, content of education is recommended for the user.
In some embodiments of the present application, before receiving the recommended content obtaining request from the display device 200, the server 300 further receives an operation rule obtaining request of the display device 200, and according to the operation rule obtaining request, the server 300 queries an operation rule corresponding to the display device 200 according to at least one of information such as a display device identifier, that is, an ID of the display device 200, or an account, and issues the operation rule to the display device 200. The operation rule is used to instruct the display device 200 to start a recommendation function. That is, the server 300 issues the operation rule corresponding to the display device 200, and indicates whether the display device 200 has the recommendation function in the operation rule. Some display devices support the recommendation function and some display devices do not support the recommendation function for different television models, different habits of different users, different regions and the like.
And according to the operation rule, enabling the display device to confirm whether to time the time of the user staying on any user interface. If the display device 200 does not have the recommendation function, the time length of the user staying on the user interface is not counted. If the display device 200 has the recommendation function, the time length of the user staying on the user interface is timed.
And S1202, calculating recommended content according to the recommended content acquisition request and preset favorite behaviors of various user portraits, wherein the favorite behaviors comprise favorite behaviors in various channels.
In the server 300 to which the display device 200 is connected, various kinds of user figures are counted. For registered users on the display device 200, their series of viewing behaviors are counted into some types, which are referred to as user portrayals. For example, children are counted as children according to their viewing behavior.
In the server 300, the favorite behaviors of various types of user portraits, i.e. the favorite behaviors of each type of user portraits under various alternative user interfaces, are preset, that is, what types of media assets each user portraits likes under each channel are set in the server 300. If the user a starts the display device 200, the user profile corresponding to the user a is obtained, and the media resources in the current channel are recommended for the user a by combining the identifier of the current channel of the user a.
In one implementation, the server 300 not only presets favorite behaviors of various user figures, but also presets current hot-broadcast media assets, and can recommend the favorite media assets and the current hot-broadcast media assets of the user when content recommendation is performed for the user.
With respect to the favorite behaviors of various types of user portraits preset in the server, the following explains the process of the server 300 for calculating the favorite behaviors of various types of user portraits with reference to the drawings. Referring to FIG. 13, a flowchart of a method for calculating a user representation's favorite behavior is provided according to an embodiment of the present invention. With reference to FIG. 13, the calculation of the user profile's preferred behavior is as follows:
s1301: and acquiring the watching behavior of each type of user image, wherein the watching behavior comprises the watching content and the corresponding watching duration of the user.
After the user starts the display device 200, the server 300 can obtain the user ID, and the server 300 also performs statistics on the viewing content of the user and the viewing duration corresponding to each viewing content. The watching behavior refers to that the user opens any watching content and watches for a period of time, for example, 5 minutes, if the user opens a certain watching content and performs flash back, and there is no watching time under the watching content, the watching behavior cannot be called as watching behavior.
