Detailed ways

The embodiments will be described in detail below, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following examples do not represent all implementation manners consistent with this application. It is only an example of a system and method consistent with some aspects of the present application as detailed in the claims.

Fig. 1 exemplarily shows a scene of a display device and a server according to the embodiment. As shown in FIG. 1, the user can operate the display device 200 through the mobile terminal 300 and the control device 100.

In some embodiments, the control device 100 may be a remote controller, and the communication between the remote controller and the display device includes infrared protocol communication or Bluetooth protocol communication, and other short-range communication methods, and the display device 200 is controlled by wireless or other wired methods. The user can control the display device 200 by inputting user instructions through keys on the remote control, voice input, control panel input, etc. For example, the user can control the display device 200 by inputting corresponding control commands through the volume plus and minus keys, channel control keys, up/down/left/right movement keys, voice input keys, menu keys, and power on/off keys on the remote control. Function.

In some embodiments, the present application provides a display method for displaying an education mode of a display device, wherein the display device may be a smart TV with a touch screen interactive function, such as a touch screen TV. It should be noted that the display device described in the present application is not limited to the above-mentioned touch-control TV, and may also be other display devices, such as a tablet computer.

Mode selection after booting

In some implementation manners, as shown in FIG. 2, when the display device is turned on for the first time, it needs to complete the boot navigation. The boot navigation mainly includes a series of initial basic settings for the display device. For example, select the language of the operation interface, initialize the connection to the network, log in to the cloud service account, and so on. The setting procedure corresponding to the boot navigation can be completed by the user's interaction in multiple successive interface setting interfaces. In practical applications, the user can first power on the display device; then turn on the physical power button on the display device or press the power button (power button) on the control device 100 to trigger a power-on event and start the operating system built into the display device; At this time, as the operating system starts and runs, the preset boot program can be loaded until it jumps to the boot navigation interface.

The boot navigation interface can preset the display sequence according to the control logic. For example, after booting up, the display device first displays the brand logo (logo), then displays the welcome interface, and transitions to the setting interface for selecting the language of the operation interface. After selecting the language of the operation interface in the user setting interface, the network connection setting interface is displayed according to the selected language. In the network connection setting interface, the user can select any wireless or wired network access point that can be accessed, and enter the relevant network setting parameters, such as WiFi password. After selecting the wireless network access point, the display device can connect to the server that provides cloud services through the selected wireless network access point. Therefore, the login interface of the server can be displayed so that the user enters the user name and password in the login interface, waits for the verification to be passed, and connects to the server to realize the normal resource acquisition and playback functions of the smart TV, and enjoy services such as UI update and synchronized playback records.

Obviously, the boot navigation is not limited to the above setting method, and may also include other setting program interfaces. For example, after connecting to the server, an interface for selecting the video type of interest is displayed, and the interface includes multiple tags, such as "movies, TV series, music, opera, technology", etc. The user selects the video type of interest in these tags, so that in subsequent use, the server can push related types of video resources to the display device.

After completing the boot navigation settings, the display device can further display the mode selection interface. As shown in Fig. 2, in the mode selection interface, multiple button controls corresponding to the modes may be included for the user to select. For example, the mode selection interface includes two selectable operation mode controls, namely "standard mode" and "education mode". Among them, the standard mode refers to the normal mode of viewing the display device. When the user clicks on the standard mode, the display device can be switched to the interactive strategy environment of the standard mode, and the control homepage corresponding to the standard mode is displayed. The education mode is an operation mode specially set for distance education. When the user clicks on the education mode, the display device can be switched to the interactive strategy environment of the education mode, and the control homepage corresponding to the education mode is displayed.

In some embodiments, the media assets used for displaying the education mode are included in the scope of the media assets displayed by the user in the standard mode, and the media assets refer to multimedia resources. Exemplarily, the education mode is used to display media assets related to children's channels and education channels in the standard mode, and media assets of channels such as movies and recommendations are not displayed.

In some embodiments, the mode selection interface may further include a prompt screen for instructing the user to select the mode. For example, as shown in Figure 2, set the designated prompt pattern on the background of the two controls of "Standard Mode" and "Education Mode"; and set the prompt text below the two controls, such as "Please select the mode you want to use, After entering the homepage, you can still switch the TV mode at will, so as to guide the user to complete the mode selection operation through graphics or text.

In the mode selection interface, the focus flag can also be set on a mode control by default according to the operating conditions of the display device. For example, after the mode selection interface pops up, the focus flag can be set on the control corresponding to the education mode by default. The user can control the focus mark to move to other controls according to the operation mode they want to enter. For example, the user uses the "left" button on the control device (remote control) to move the focus mark to the control corresponding to the standard mode. Obviously, the focus mark can present different display shapes according to different interface styles. For example, the focus mark can be a box that selects the control; it can also be a processing mark for highlighting or changing the color of the control, thereby indicating the position of the focus.

In some embodiments, the mode selection interface presented by the display device may also change according to the change of the user's control action. For example, as the focus mark is switched between the two controls, the prompt pattern and prompt text on the interface will also change, that is, the description interface and description content corresponding to the control mode will be converted.

When the user selects the "education mode" control in the mode selection interface, the operating system of the display device can further jump to the interface related to the education mode.

In an exemplary embodiment, after selecting the "education mode" control, a verification interface may pop up. An input box may be included in the verification interface for the user to enter the user name and password. It can also include other controls related to authentication, such as a "login" control. After the user enters the user name and password, by selecting the login control, the display device is instructed to send the user name and password information entered by the user to the server for verification. If the verification is passed, the relevant interface of other education modes will continue to be displayed; if the verification fails, the display device will display a verification failure prompt screen, or exit the education mode.

In this embodiment, the verification failure prompt screen can also display the reason for the verification failure. For example, when the information entered by the user is wrong, the prompt screen can display "The entered user name or password is wrong, please output again"; Due to network reasons, if the verification result is not obtained within the preset time, the prompt text such as "connection timeout/cannot connect to the server, please try again" can be displayed on the prompt screen.

Since the education mode and the standard mode are two operation modes under the same display device, in some embodiments, the authentication interface can share the same user name with the standard mode. You only need to enter the password when entering/exiting the education mode. Can.

In an exemplary embodiment, an independent entry password, that is, a parent password, can also be set for the education mode. Correspondingly, after selecting the education mode in the mode selection interface, the password interface will pop up directly, as shown in Figure 3. In the password interface, a virtual keyboard control can be displayed for the user to enter password information. In order to facilitate the completion of interactive operations on the display device and to simplify the number of characters input by the user, the entry password corresponding to the education mode can be a pure digital password, such as a simple password with 4 or 6 digits. Correspondingly, the virtual keyboard control displayed in the password interface can also be a pure numeric keyboard control.

For the independent entry password set in the education mode, the entry password can be verified by the display device after the password is entered, so as to quickly obtain the verification result and complete the verification; the password can also be sent to the server for verification, and the server returns the verification result. So that there is no need to set a password multiple times on different display devices.

In an implementation manner, in order to enter the control homepage corresponding to the education mode, after the password verification is passed, a level selection interface for limiting the content of the control homepage, such as a grade selection interface, an age selection interface, etc., may also be displayed. As shown in Figure 3, in the grade selection interface, multiple grade options can be preset according to the actual education system, such as "children, first grade, second grade,..., senior third" and so on. The user implements interactive operations through the remote control or directly touches and moves the focus mark, and the corresponding options can be selected. After the user selects the corresponding grade option, the display device will send the selected grade option label information to the server, so that the server pushes the relevant educational resource content to the display device according to the selected grade option for display in the control homepage.

Obviously, multiple grade options can be selected in the grade selection interface at the same time to meet different educational needs, so multiple grade options in the grade selection interface are multiple selection options. After each option is selected, the mark that the option has been selected can be displayed, such as adding a dot or a check mark on the corresponding control pattern of the option. Correspondingly, the grade selection interface can also be provided with an "OK" control, so that after selecting multiple options, click the OK control to complete the grade selection to perform the subsequent steps.

It should be noted that when jumping to the grade selection interface, the focus cursor can be set on the first option by default, for example, on the option corresponding to "Junior" in Figure 4 for the user to select. It is also possible to obtain the user data stored in the server from the user name logged in the boot navigation step, so as to set the focus cursor to the option corresponding to the grade data by default based on the grade data suitable for the user data.

Since multiple grade selection options can be included in the grade selection interface, more optional grade selection options can also be included according to different school age classification methods, so in the displayed grade selection interface, it may not be on one page of the screen All options are fully displayed. To this end, you can set all the grade options in the grade selection interface through the scroll display. For example, in the grade selection interface shown in FIG. 4, only 9 grade options may be displayed, that is, from "children" to "eighth grade", forming a 3×3 array of options and displaying them in the middle area of the display. The "ninth grade" to "senior sophomore" option icons are partially displayed on the lower edge of the screen. When the user presses the "Down" button on the remote control when the focus cursor is at the bottom row (for example, on the "6th grade" option); The option icon moves up and is displayed in the middle area of the screen for users to choose.

After the user selects at least one grade option, the display device can jump to the control homepage of the education mode, as shown in Figure 5. Before displaying the specific content of the education mode homepage, the display device may also send a homepage request instruction containing the selected grade option information to the server. In response to the received homepage request instruction, the server may return the homepage configuration file to the display device according to the grade option information contained therein. After the display device receives the homepage configuration file, it can parse the recommended resources in the homepage configuration file, and add corresponding images and links of the recommended resources in the homepage layout.

For example, in the grade selection interface, the user selects the "children" option. After the motor confirms the control, the display device can send a homepage request instruction with the information of the "children" option to the server. Correspondingly, the server can obtain the "children" option information in the homepage request instruction, extract the tags or links of the curriculum resource content for children according to the preset recommendation rules, generate the homepage configuration file, and return the homepage configuration file to the display device, In order to make the display device display the corresponding education mode homepage.

Realization of sharing a set of homepage data on different homepages

In some embodiments, the display device may have a built-in terminal APP to display media assets, and the mode selection interface may be the interface after the application is launched for the first time. In order to meet the viewing needs of different target groups, the terminal APP can be set with multiple scene modes, and different media assets can be displayed in different scene modes. When the user switches the scene mode, the terminal APP needs to switch the current page of the display device to the home page of another scene mode. Since the homepage data supported by different TV models and different APP versions may be different, if you adapt the homepage of multiple scene modes separately for each TV model and each APP version, it will greatly increase the cost of homepage development and maintenance.

In order to solve the above problems, this application selectively displays the homepage data, so that a homepage with multiple scene modes can be virtualized based on one homepage data, which effectively reduces the cost of homepage development and maintenance.

In some embodiments, the scene mode of the display device may include a first scene mode and a second scene mode. The first scene mode may be a standard mode. In this scene mode, the homepage can display multiple types of media assets. Suitable for ordinary users to watch; the second scene mode can be an education mode, in this scene mode, the homepage can only display educational media resources, suitable for children to watch.

In some embodiments, the method for displaying the homepage on the display device may include the following steps:

Receive an operation instruction to enter the homepage input by the user; obtain homepage data from the server in response to the operation instruction for entering the homepage; select the first mode from the homepage data according to the scene mode of the homepage as the first scene mode Data, according to the first mode data to control the display to display the first homepage; according to the scene mode of the homepage as the second scene mode, select the second mode data from the homepage data, and control the station according to the second mode data The display displays a second home page, wherein the second mode data is different from the first mode data.

In some embodiments, the display device can enter the home page in the standard mode by default after being turned on. Therefore, the operation instruction to enter the home page input by the user may be a startup instruction of the display device.

In some embodiments, the user can switch the display device to another scene mode when the display device is in one scene mode, for example, switch the standard mode to the education mode, or switch the education mode to the standard mode. When the device switches the scene mode, it needs to display the home page of the new scene mode. Therefore, the operation instruction to enter the home page input by the user may also be an operation instruction to switch the scene mode.

In some embodiments, when the display device is in a scene mode, the user enters some secondary pages, tertiary pages and other pages from the home page of the display device. When the user returns to the home page, the display device needs to display the home page again. Therefore, The operation instruction to enter the home page input by the user may also be an operation instruction to return to the home page from other pages.

In some embodiments, the display device may have multiple control methods such as touch control, voice control, remote control control, mobile phone control, etc. The above-mentioned operation instructions for entering the homepage can be implemented by any control method.

In some embodiments, after receiving an operation instruction to enter the homepage, the display device establishes a communication connection with the server, obtains homepage data from the server, and caches the homepage data.

In some embodiments, the homepage data received by the display device includes homepage data of multiple scene modes, such as first mode data and second mode data, where the first mode data is used to generate the homepage of the first scene mode, and the second The mode data is used to generate the first page of the second scene mode. The display device can filter the first mode data from the home page data according to the scene mode of the home page as the first scene mode, generate the first home page according to the first mode data, and control the display to display the first home page.

In some embodiments, the first mode data and the second mode data may be mutually exclusive data, so that the first homepage and the second homepage can display completely different content. The second mode data may be provided with a preset identifier to distinguish it from the first mode data. According to the scene mode of the homepage as the first scene mode, data other than the data of the second mode can be selected from the homepage data, that is, data without a preset identifier, as the first mode data.

In some embodiments, the first mode data and the second mode data may be partially the same data. For example, the first mode data includes all or part of the second mode data. In addition to the second mode data, the first mode data may also be Other data is included so that the first home page and the second home page can display part of different content, as long as the first home page and the second home page can be distinguished. According to the scene mode of the homepage as the first scene mode, all the homepage data can be regarded as the first mode data.

In some embodiments, the display device may filter the second mode data from the home page data according to the scene mode of the home page as the second scene mode, generate the second home page according to the second mode data, and control the display to display the second home page.

In some embodiments, the second mode data may be provided with a preset identifier to distinguish it from the first mode data. According to the scene mode of the homepage as the second scene mode, the data with the preset identifier can be selected from the homepage data as the second mode data.

In some embodiments, when the user inputs the operation instruction to switch the scene mode within a short time after inputting the operation instruction to enter the homepage, or the user inputs the operation instruction to switch the scene mode within a short time after inputting the operation instruction to switch the scene mode. Scene mode operation instruction, the display device can receive the operation instruction of switching scene mode newly input by the user, select the home page data of another scene mode from the cached home page data, and control the display to switch the current home page to the switching scene The home page corresponding to the operation command of the mode. Using cached homepage data to switch the homepage can increase the speed of homepage switching and improve user experience.

In some embodiments, the display device may also start execution from the step of receiving the operation instruction to enter the homepage input by the user according to the operation instruction for switching scene mode input by the user, and generate the homepage corresponding to the operation instruction for switching scene mode.

In order to further explain the home page data obtained by the display device, an embodiment of the present application also provides an interactive schematic diagram of the home page display. See FIG. 6, which is an interactive schematic diagram of the home page display according to some embodiments. In Figure 6, the JUUI APP can be a terminal APP of the display device, and the operator can use CMS (Content Management System, content management system) to organize the home page, and then store it in the converged DB (database, database).

In some embodiments, the homepage arranged by the operator may include a standard mode homepage and an education mode homepage, where both the standard mode homepage and the education mode homepage are set with three levels: navigation, channel, and column. According to this level setting, the homepage data can be Divided into multiple sets of navigation data, each set of navigation data includes multiple sets of channel data, and each set of channel data can include multiple column data. In order to achieve the display effects of multiple homepages, the operator can mark the navigation data to divide multiple sets of navigation data into different homepages.

In some embodiments, a way to mark navigation data is to set a preset identifier for navigation data that needs to be displayed in education mode, such as edubox_, and navigation data that needs to be displayed in standard mode do not set a navigation identifier, so that edubox_ starts with edubox_ The navigation data belongs to the data displayed in the education mode, that is, the second mode data. The navigation data without the navigation mark belongs to the data displayed in the standard mode, that is, the first mode data; or, the navigation data beginning with edubox_ can also be set to belong to In the data displayed in the education mode, all navigation data belong to the data displayed in the standard mode.

Of course, in actual implementation, it is not limited to the above-mentioned marking methods, and other methods can also be used. For example, the navigation data that needs to be displayed in the education mode and the navigation data that need to be displayed in the standard mode are respectively set with a different navigation mark; or only need to be displayed in the standard mode. The navigation data displayed in the mode is set with a navigation mark, and the navigation data that needs to be displayed in the education mode is not set; or the navigation data that needs to be displayed in the education mode and the navigation data displayed in the standard mode are set to a different status data, as long as The scene mode of the navigation data can be distinguished, so that the standard mode and the education mode can display different navigation data.

In some embodiments, the navigation data in the homepage data includes the control data of the navigation bar and the layout data of the navigation bar, the channel data includes the control data of the channel bar and the layout data of the channel bar, and the column data includes each recommended position. Typesetting data and selectable media asset data. For example, the selectable media asset data is the most popular media asset data. The homepage data compiled by the operators can be called the homepage raw data, and the operators store the homepage raw data in the converged DB.

After the user enters the operation instruction to enter the homepage through the JUUI APP, the JUUI APP can obtain the homepage data from the online subsystem.

The online subsystem can retrieve the original data of the homepage by accessing the fusion DB, and obtain media asset data from the content subsystem according to the obtained original data of the homepage. In some embodiments, the online subsystem obtains media asset data from the content subsystem according to the media asset data selected by the recommended position.

In some embodiments, the online subsystem also obtains the model version capability data from the PDS system, and filters the media asset data from the content subsystem according to the model version capability data to obtain the model and JUUI APP version suitable for the display device For example, according to the most popular media asset data in different fields, including TV series A, variety show B, and short video C, according to the JUUI APP version, the media asset type corresponding to the recommended position is TV series, then variety B and short videos are filtered C gets the media asset data that adapts to the JUUI APP version as TV series A.

In some embodiments, the online subsystem merges the operation data with the filtered media asset data, generates homepage data, and returns the homepage data to the JUUI APP, where the operation data includes the original homepage data.

In some embodiments, after the JUUI APP receives the homepage data, it filters the homepage data to match the current scene mode. For example, according to the current scene mode as the standard mode, only the standard navigation is displayed, that is, the navigation data starting with edubox_ is excluded, and the first homepage is generated according to the remaining navigation data; according to the current scene mode as the education mode, only the education navigation is displayed, that is, edubox is reserved The navigation data starting with _ excludes other navigation data, and the second homepage is generated based on the navigation data starting with edubox_.

Refer to FIG. 7, which is a schematic diagram of the home page in the standard mode according to some embodiments. As shown in FIG. 7, the home page is the first home page, and the navigation bar is provided with multiple operation controls, such as: "my", "channel", " Movies, "VIP", "Pandemic", "Mall", "Games", "Apps" and "Discovery", when users trigger different operation controls on the navigation bar, they can enter different navigation pages.

In some embodiments, a mode switching control may be provided above the navigation bar. In the standard mode, the mode switching control may be displayed as "education mode" to prompt the user to switch the current mode to the education mode. In the education mode, The mode switching control can be displayed as "standard mode" to prompt the user to switch the current mode to the standard mode.

In the standard mode, when the user triggers the mode switch control, the display device can enter the homepage of the education mode. The user triggers the mode switch control to select the mode switch control with the remote control, and then confirm the entry. When the display device has a touch When the display device has a voice control function, the user can also send a voice command to the display device to trigger the mode switch control. When the display device communicates with a smart terminal such as a mobile phone, the user can directly touch the mode switch control. The smart terminal can also be used to issue a mode switching instruction to the display device.

In some embodiments, when the user needs to manipulate the display device in the standard mode, in order to prevent the user from switching the standard mode to the education mode by mistake, the display device may also be configured to require a password when entering the education mode for the first time. When the user needs to control the display device in the education mode, in order to provide the user with more accurate homepage data, the grade selection page can also be displayed when the user enters the education mode for the first time, for the user to enter the grade. When the user is not entering the education mode for the first time, he can directly display the home page of the previously selected grade. For details, see Figure 8, which is a schematic flow diagram of the second home page entry method according to some embodiments. As shown in Figure 8, the method may include the following step:

Step S401E: Determine whether the user enters the second scene mode for the first time.

Step S402E: If the user enters the second scene mode for the first time, control the display to display a password input interface.

Step S403E: Receive the password information input by the user.

Step S404E: According to the password information input by the user consistent with the preset password information, control the display to display multiple grade option controls.

Step S405E: Receive an operation instruction of one of the grade option controls input by the user.

Step S406E: If the user is not entering the second scene mode for the first time, select the home page data corresponding to the grade option control from the second mode data.

Step S407E: Control the display to display a second home page according to the home page data corresponding to the grade option control.

In some embodiments, it can be set by default that the user needs to set password information and grade information when entering the second scene mode for the first time. After the user sets the grade information, the display device stores the grade information in a preset storage path. Therefore, when the user After inputting the operation instruction to enter the homepage, the display device can determine whether the user enters the second scene mode for the first time according to the grade information in the preset storage path. If there is no grade information in the preset storage path, it is determined that the user is entering the second scene mode for the first time, and step S402E is continued. If there is grade information in the preset storage path, it is determined that the user is not entering the second scene mode for the first time, and you can skip Go to step S406E.

Step S402E: If the user enters the second scene mode for the first time, control the display to display a password input interface.

In some embodiments, after determining that the user enters the second scene mode for the first time based on the grade information in the preset storage path, the password input interface may be displayed to prompt the user to enter the password. In some embodiments, the password may be JUUI APP The password of the account, the user enters the password, the display device can continue to display the second homepage, which can improve the privacy security of the education mode.

Step S403E: Receive the password information input by the user.

Step S404E: According to the password information input by the user consistent with the preset password information, control the display to display multiple grade option controls.

In some embodiments, according to the password entered by the user and the preset password, for example, the password of the JUUI APP account is consistent, the display can be controlled to display the grade selection page.

Refer to FIG. 4, which is a schematic diagram of an interface of a grade selection page according to some embodiments. As shown in Figure 4, the grade selection page can select multiple grade option controls, such as "children", "first grade", "first grade", "second grade", "third grade", "fourth grade", and "fifth grade". "," "sixth grade", "seventh grade", "eighth grade" and so on, the user can select a grade option control according to the control mode supported by the display device, for example, according to the display device supports touch, click the "third grade" control , Generate an operation instruction corresponding to the grade option control, and the operation instruction is a touch instruction.

Step S405E: Receive an operation instruction of one of the grade option controls input by the user.

The display device receives the user's operation instruction. For example, when the user's operation instruction is a touch instruction, the operation instruction of the grade option control can be a touch signal, and the touch screen of the display device sends the touch signal of the grade option control To the controller of the display device, the controller of the display device determines the grade option control touched by the user according to the coordinate area corresponding to the touch signal.

Step S406E: If the user is not entering the second scene mode for the first time, select the home page data corresponding to the grade option control from the second mode data.

In some embodiments, according to the grade selected by the user in step S405E, the navigation data corresponding to the grade can be selected from the second mode data.

In some embodiments, according to the judgment in step S401E that the user is not entering the education mode for the first time, the navigation data corresponding to the grade can be directly selected from the second mode data.

Step S407E: Control the display to display a second home page according to the home page data corresponding to the grade option control.

In some embodiments, according to the grade selected by the user, the second homepage of the grade is displayed. Refer to FIG. 5, which is a schematic diagram of the interface of the second homepage according to some embodiments.

As shown in Figure 5, the navigation bar of the second homepage can be provided with an operation control, which can be displayed as the grade selected by the user, such as "third grade", and the user can reselect the grade according to the operation control.

A channel bar can be set at the bottom of the second homepage, and the channel bar can be set with multiple operation controls, such as "my", "synchronized lesson", "live lesson", "picture book", "learning", "AR" and " application". The user enters different channels according to these operation controls.

It can be seen from the above embodiment that the home page data in the embodiment of this application is divided into the first mode data and the second mode data. The display device can directly obtain all the home page data. According to the scene mode of the home page as the first scene mode, select the first mode The data generates the first homepage, and selects the second mode data to generate the second homepage based on the scene mode of the homepage as the second scene mode, so that the server can generate two homepages based on a set of homepage data, reducing the cost of homepage generation and maintenance.

In some embodiments, the mode switching control can be set as a hidden control, which is displayed after the user inputs a preset operation.

In some embodiments, there are different judgment and processing logics after receiving two return key values in different scenarios. When the user presses the return key twice or more for the first time in a row, a switching prompt is displayed at the position of the corresponding mode switching control to remind the user to switch the position of the control. After the prompt is displayed, the user first cancels the prompt and selects the switching control to perform mode Switch. This can deepen the user's impression.

In some embodiments, after the prompt appears a preset number of times, the prompt is no longer performed. Therefore, it is necessary to determine the number of impressions before the prompt is displayed. If the prompt is reached, it will not be displayed, otherwise, it will be displayed.

Interaction in Educational Mode

The education mode homepage is used to provide users with basic interactive operations, such as selecting a course to play, executing a setting program, launching any application, switching operation modes, and so on. In order to support the above interactive operations, as shown in Figure 9, the education mode homepage can include multiple display areas, for example, the Header area at the top of the displayed homepage, the content area at the middle of the displayed homepage, and the switch at the bottom of the displayed homepage. District (channel Tab).

In an exemplary embodiment, the Header area is used to display functional controls, for example, "mode switch", "voice", "search", "user", "grade", and "points" in order from left to right. , "Wifi status", "time", etc. The user can realize the corresponding function by moving the focus mark to any functional control.

In practical applications, the content and number of functional controls contained in the header area can be configured by the server to adjust the display layout of the header area according to the needs of different time periods. Among them, the "mode switch" control can be used to switch the current operation mode of the display device. When the user clicks or moves the focus mark to the "mode switch" control, it will directly switch from the education mode to the standard mode.

The "Voice" control can be used to call the built-in intelligent voice system of the display device. When the user moves the focus cursor to the "Voice" control, the built-in intelligent voice system of the display device can be activated, and the voice input device, such as a microphone, can be used. Enter the voice message for voice search. Obviously, in order to meet the needs of the current education model, when you select the "voice" option in the education model homepage to search, the search content can be limited to children and education-related content.

The "Search" control can be used to jump to the search interface after the user clicks it, and at the same time accept the keyword text information input by the user to start the search engine and obtain the search results.

The "User" control can display the currently logged-in account information. If the account is not currently logged in, it will be displayed as the account login/registration portal. When the user clicks on this control, it will jump to the account information page. If the account is currently logged in, the user's avatar, nickname, and other identification patterns can be displayed after logging in. Obviously, the displayed user nickname has a limit on the number of characters, and the excess characters can be replaced with ellipsis.

The "grade" control can directly display the grade options selected by the user on the grade selection interface. For example, if the user selects the "third grade" option, the "grade" control will directly display "third grade". If the user clicks on the "grade" control on the homepage of the education mode, they can jump to the grade selection interface; if the user does not select the grade option, they can display "grade selection" in the position of the "grade" control to guide the user to jump to the grade Select the interface.

The "Points" control is used to display the points value of the currently logged-in account. During the display process, the points logo pattern and the number of points can be included. Among them, according to the characteristics of the system, the points can be designated as a specific name, and different names have different patterns. For example, when the points are called "Golden Beans", the displayed pattern can be a golden bean graphic; the displayed value can be directly the value of the points owned by the currently logged-in account. Click the "Points" control to jump to the points interface, which can include points record, recharge, redemption, etc.

The "wifi status" control can specify the current network connection status through a variety of network status identifiers. When the user clicks on the "wifi status" control, they can jump to the wifi setting interface. The wifi setting interface can include a list of connectable networks, as well as content for switching, setting, and connecting to wifi.

The "Time" control is used to display the current time. The display time format can be automatically adjusted according to the current page layout. For example, you can set the "wifi status" control and the "time" control to display in the upper right corner of the page. If the display space is sufficient, you can display both the date and time; if the display space is insufficient, you can only display the time, and when the user When clicked, it jumps to the calendar interface. Obviously, in some embodiments, when the user clicks, it can also jump to the time setting interface.

You can also display the "VIP" control in the Header area. If the currently logged-in account has purchased a VIP, the VIP special logo, validity period and renewal label can be displayed. Among them, if the currently logged-in account has purchased multiple VIPs, the displayed validity period may be the VIP validity period expiration time with the longest remaining time. Correspondingly, when the user clicks on the "VIP" control, they can jump to the renewal page. If the currently logged-in account does not purchase a VIP, you can display the activity copy of the purchase guide, such as "Limited Time 20% Off" and so on. The text displayed in the position of the "VIP" control can limit the number of words in the text box, and the excess part is displayed in the form of scrolling (horse racing lights).

As the main display area for displaying the homepage, the content area can be used to present education-related resource patterns and text so that the user can select any resource in the content area to play. The content area can be spliced with a variety of templates with preset layouts from homepage posters, and each module can be further displayed as card controls with different functions. For example, include: "course details page", "topic", "category", "single episode", "VIP purchase", "learning record", etc. The user instructs the display device to enable the corresponding function by clicking each card control. For example, after the user clicks the "Course Details Page", the display device can display the detailed information of the course and display the playback controls at the same time, so as to realize the playback of the corresponding course resources.

Multiple labels can be set in the switching area to switch between different display pages. For example, each label in the switching area represents a channel homepage, and the user can set the focus mark on different labels to display different channel homepages in the content area. As shown in Figure 9, in the switching area, the following channels are displayed in sequence: "My", "Synchronized Lesson", "Live Lesson", "Picture Book", "Learning", "AR", "Application" and other channels. The number, icon, name, and order of the channel homepage can be configured through the server. You can also specify which channel homepage is the default homepage according to different usage scenarios.

The channels referred to by tags in the switching area can be further divided into age-specific channels and general channels. For example, "My", "Learning", "AR", and "Apps" belong to general channels; "Synchronized Course", "Live Course", "Picture Book", and "Audio" belong to age-specific channels. Obviously, some channels can be shared by multiple grades.

Since the controls in the switching area are often used to switch the channel homepage, the number of controls in the switching area should be displayed within one screen page. Accordingly, the limited number of labels and each label can be given according to the display area size and resolution of the display device. The word limit of the label.

When the user switches to the "My" channel in the switching area, the content displayed in the content area can be changed to the channel homepage corresponding to the "My" channel. The channel homepage corresponding to the "My" channel can include multiple function cards. For example, as shown in Figure 10, the function card may include: "Basic Account Information", "Education Mode Management Entry", "Education Study Report", "User Consumption Record", "Collection Entry", "VIP Purchase Entry", "Mobile app/WeChat public and other drainage portals" and other additional functions.

Multiple function cards can be spliced in an array to form the entire content area. The size and setting position of each function card can also be adjusted according to the corresponding frequency of use of different function cards. For example, basic account information, education mode management entrance and education learning reports are used frequently, so the display area of function cards can be increased, such as displaying these three function cards in the upper area of the content area; and the frequency of use of other additional information It is very low, so it can reduce the display area of the corresponding function card, and only display it in the bottom row of the content area.

After clicking on different function cards, you can jump to different interfaces. For example, click on the basic account information card to jump to the corresponding basic account information page. Click on the function card corresponding to the education mode management entry to set the education mode, such as setting the viewing time.

It should be noted that in the education mode, the content presented when clicking the function card should be related to education. For example, when clicking the user's consumption record function card, the user's consumption record information can be displayed, but the displayed content needs to filter other consumption records other than children, education, and online learning. In the same way, after clicking the collection entry function card, the displayed collection interface only includes children's movies, educational resources, online learning, etc., and the collection content in the standard mode is not displayed.

The mobile phone app/WeChat public and other drainage portals can display the QR code pattern provided by the operator. When the user scans the QR code through a mobile terminal such as a mobile phone, the user can jump to the designated app download page or follow page. The functions specified by the QR code can also be adjusted according to different application environments.

In addition, the card corresponding to the additional function can be used to display some additional information or call other functions after clicking, such as "point card exchange", "customer service phone", "version information", "local information" and so on. Among them, click the "Point Card Exchange" function card to jump to the point card exchange interface; click "Customer Service Phone" to display the customer service information of the operating system or display the customer service information of the device; click "Version Information" to display the version information of the current operating system , And when there is a new version, the update prompt will be displayed. When there is no new version, it will display "the latest version" and the corresponding version number; click "this machine information" to display the machine name, software version number and other information.

As an important channel in the education mode, the "learning" channel can also be selected to display a screen containing multiple function cards in the content area. Further, as shown in FIG. 11, the screen displayed in the content area can be further divided, for example, including two areas of "learning records" and "purchased courses". Among them, the "learning records" area can be used to display the playback records of multiple course resources and the records of watched online live courses. Obviously, for the playback record of the course resource, you can continue to play it at the last time you watched it after you click it; and for the online live course, you can jump directly to the corresponding live room screen after you click it. The "Purchased Courses" area is used to display links to various courses purchased by the current account, such as live courses, VIP course classification entrances, etc. For the purchased VIP courses, information such as the course/VIP name and validity period can be displayed on the corresponding card.

Recommend courses in the subscription list

In the actual display process, each area can include multiple display positions to display multiple function cards. The display position in the same area should include at least one row. When there is less than one row, the recommended course card can be used to make up. For example, as shown in Fig. 12, when the "learning records" is less than one row, after displaying the course records, the recommended course cards with the same number of remaining display positions can be determined through big data to supplement the remaining display positions.

Similarly, when the "purchased courses" is less than one row, after displaying the purchased courses or VIP courses, the recommended course cards with the same number of remaining display positions can be determined through big data to supplement the remaining display positions. Obviously, in order to facilitate the user to distinguish learning records (or purchased courses) and recommended courses, tags containing words such as "recommendation" and "advertisement" can be added to the recommended course card.

In an exemplary implementation manner, the indication text of the area can also be adjusted according to the content to be displayed in each area. For example, as shown in Figure 13, if there is no learning record, the title of the learning record can be changed to "No learning record, recommended for you", and at the same time, a recommended course card is displayed in each display position of the "Learning record" area. Similarly, as shown in Figure 14, when there is no purchased course, you can change the title of the purchased course to "Not yet purchased course, guess you like it", and at the same time on each display position in the "Purchased course" area Show recommended course card, you can also use VIP purchase card to replace any recommended course card.

Management of offline media assets

In some embodiments, the homepage data of the user TV terminal is arranged in the background. After querying the database for the terminal to obtain the arrangement data, it is necessary to call the content system interface to obtain the media asset details, including the media asset poster, name, and enter the parameters ( filterOffline=true) tells the content system that it needs to filter out the online status of online as offline. At this time, the content system will only return the media assets that are online, and then encapsulate and distribute the data returned by the content to the terminal.

The user has purchased the page data, and the terminal-oriented first calls the membership interface to obtain all the courses that the currently logged-in user has purchased, and then also calls the content interface to obtain media information details, but at this time calls the content system input parameter (filterOffline=false) to tell the content system not to filter Online is offline media assets. In addition to obtaining the basic information of media assets, the data obtained on this page also requires the content system to return the operational online and offline status available, the third-party online and offline status status, the sold-out status shelves, and the course online and offline status online. At this time, if a certain course purchased by the user has been sold out (shelves=0), the online status of the course in the content system is the offline status (online=0), but because we entered the parameter filterOffline=false, the content system is still Details of the course will be returned. When delivering courses to the terminal, it will judge the media assets with the operational online status available = 1, and the third-party online status status = 1, that is, if they have sold out shelves = 0, they will also be delivered.

In the embodiment of the present application, the request sent by the display device 200 for displaying the interface with the media asset data is called the media asset request, and the data fed back by the server 400 according to the media asset request is called the issued data. The display device 200 can adjust the specific content on the display interface according to the received data to present different media asset interface effects. For example, when the user enters the control homepage through interactive operations, the operating system in the display device 200 can provide a basic UI display architecture, and then send a media asset request to the server 400 to obtain the distributed data, and then add the content in the distributed data Into the basic UI display structure to form a complete control homepage.

The distributed data can usually be parsed by the display device 200 to form a content area for displaying the control homepage, for example, a poster (pattern), link, profile information, etc. of specific media assets are displayed in the content area of the control homepage. Correspondingly, the issued data can carry corresponding basic media information and detailed information.

For the specific interface presented by the display device 200, there are various interfaces that need to use the issued data to complete the display, for example, a homepage interface, an activity interface, a purchased interface, and so on. Among them, the media assets displayed in the homepage interface and the activity interface can generally be uniformly issued by the server 400 according to the current operating status, so that the display device 200 can complete the display on the corresponding interface. The media assets displayed in the purchased interface are usually media assets that have been purchased or played by the user, and have an association relationship with user information.

The media information is provided by the server 400 or may be provided by the server 400 accessing a third-party database. Media assets generally include various video, audio, and graphic resources that can be played on the display device 200, as well as video streams, audio streams, data streams, etc. formed in real time through a web live broadcast platform. Different media assets can be set with different playback permissions. For example, some media assets may be media assets that need to be purchased additionally, such as VIP resources, paid live broadcasts, and so on. These media assets that need to be purchased additionally will be set up with certain discount activities as the operation activities proceed. For example, set a price reduction campaign in a specific time period, etc. Media assets with discount activities can be displayed through the homepage interface, event interface, and other frequently accessed interfaces, so that they can be recommended to users and get relevant event information in time.

The validity period of the activity can also be set in the operation activity. When the activity ends, the operation server will sell the corresponding media assets and remove them from the shelves. For example, the activity interface for a live course may be displayed as the interface shown in FIG. 15. In the course details interface, the detailed information of the corresponding live course can be displayed, including the course name, lecturer information, class time information, live broadcast time, etc., and can also include specific event information, including original price, current price, start and end time, etc.

If the user purchases the corresponding media assets, the corresponding display content can be adjusted in the event interface or the homepage interface to mark that the course has been purchased. As shown in Figure 16, part of the information in the activity interface can be replaced with course-related playback information, including viewing progress, number of interactions, and so on.

The purchased media assets can also be displayed on the purchased interface. As shown in Figure 17, in the purchased interface, all the course information that has been purchased under the current user information can be displayed, and the course status can be identified through different tags, such as "purchased", "expired", etc.

Based on the above interface display method, when the event is over, the operation server will process the courses sold out. At this time, when the server 400 sends data to the display device 200, it will filter such courses so that they can be displayed on the home page interface and the event. The user interface is no longer displayed in the interface. However, for users who have already purchased during the event, they still need to display relevant courses on the purchased interface for playback. Therefore, the server 400 still needs to distribute these sold-out courses to the purchased users. Therefore, for different display interfaces, a different display interface is required. A mechanism to ensure that the courses sold out are shown to users in different scene interfaces.

In order to realize the above-mentioned display mechanism, some embodiments of this application provide a method for distributing media asset data. As shown in FIG. 18, the method for distributing media asset data provided by this application includes the following steps:

S1B: Request to obtain media assets.

The media asset request is a request sent by the display device 200 to the server 400 for displaying any interface containing media asset content on the display 275 of the display device 200. The media resource request may be automatically generated by the display device 200 according to the user's interactive operation action, and sent to the server 400. For example, in the process of the user powering on and entering the control homepage, since the content of the media asset needs to be displayed on the control homepage, the display device 200 may automatically send a media asset request to the server 400 before the control homepage is displayed.

In order to make the content contained in the displayed screen diversified to better meet the viewing needs of different users, the media asset request may include user information and display interface types. Among them, the user information, as the identification information of different users, can be a user account logged in the current operating system, or different user information can be selected according to different operation modes. For example, in the display device 200 with an education mode, after the user chooses to enter the education mode, he can select different combinations of information such as age, grade, and main learning content according to preset options, so as to generate a corresponding combination of information. The user information is sent to the server 400.

In the case of user information not logged in, the operating system of the display device 200 can automatically jump to the login interface for the user to complete the login, and after the user completes the login, the media asset request is automatically generated according to the logged-in user account. The display device 200 can also determine a general media asset recommendation information as user information according to the statistical data of the media asset playing process, so that the general media asset recommendation information can be used to generate a media asset request when the user information is not logged in.

The display interface type is used to indicate what kind of interface the user wants to display on the display device 200. In the embodiment of the present application, the display interface type is one of the first type of interface or the second type of interface. Among them, the first type of interface refers to interfaces that do not need to display media assets that are removed from the shelves, such as the home page interface and the activity interface. Generally, the media assets displayed in the first type of interface are related to the operation activities of the server 400, and the media assets content is updated more frequently. Therefore, the media assets that have been removed do not need to be displayed, and more display space is reserved. Other media content.

The second type of interface refers to an interface that needs to display all media assets under user information for a long time, such as a purchased interface. Generally, the media assets displayed in the second type of interface are related to user information, and their content is usually updated with the user’s purchase behavior. Therefore, media assets that have been removed from the shelves but purchased by users still need to be displayed until the media assets It is completely invalid or the user manually deletes the content of the media asset. In some embodiments, the second type of interface may also include at least one of a viewing history interface, a history interface and other interfaces that display all media assets under user information for a long time.

In some embodiments, the user controls the display or switching of the interface by inputting instructions, and the display device sends a media asset request according to the identity of the interface to be displayed. In some embodiments, the media asset request includes user information and an interface identifier.

In some embodiments, before receiving the issued data issued by the server, the display device displays the corresponding interface, and loads the interface according to the stored historical data or preset data, and updates the interface after receiving the issued data. Interface and stored historical data.

S2B: In response to the media asset request, extract and deliver data according to the user information.

After the server 400 receives the media asset request sent by the display device 200, it can extract the user information carried in the media asset request, and query the media asset data under the user information through the user information database to form distributed data. The delivered data may include all media assets under the user information, that is, media assets that have been purchased by the user but are already in the off-shelf state.

For example, the server 400 determines that the current user information includes the learning grade set by the user as the third grade by reading the received media asset request, and can extract the media asset content corresponding to the "third grade" based on the user information. At the same time, if the limited-time discount course of "Classics of Chinese Studies" has been purchased under the user information, but the course has passed the discount period and is in a sold-out state, the server 400 also needs to extract the media resources of the course "Classics of Chinese Studies" , And then get the issued data.

Before sending the distributed data to the display device 200, the distributed data may also be filtered, so as to send distributed data of different contents according to different display interface types.

S3B: If the display interface type is the first type interface, delete the off-shelf media asset in the delivered data.

By reading the display interface type in the media asset request, when it is obtained that the interface that the current user wants to display on the display device 200 is the first type of interface such as the homepage interface or the active interface, the server 400 can remove the media in the issued data. Delete the media assets so that the media assets do not need to be displayed in the display interface.

For example, the server 400 reads the received media asset request and determines that the display interface type specified in the media asset request sent by the current user is the display control homepage. Since there is no need to display media assets that have been removed from the shelves on the control homepage, the server 400 can delete the media assets of the "Classic of Chinese Studies" course that has been removed but the user has purchased, and only sends "third grade" to the display device 200. Corresponding media content.

It should be noted that the deletion described in this embodiment does not delete all the media asset data, but when the display interface type is the first type of interface, the media asset is not sent to the display device 200 to be removed, thereby reducing the number of media assets that are sent to the display device. 200 The amount of data sent. Further, the distributed data sent by the server 400 to the display device 200 refers to basic information and detailed information that can be displayed in certain interfaces, and is not the media asset file or the video stream data itself. For the media asset file or video stream data, only after the user selects to play in the corresponding interface, the media asset file or video stream data is sent to the display device 200.

S4B: If the display interface type is the second type interface, reserve the off-shelf media assets in the issued data.

By reading the display interface type in the media asset request, when it is obtained that the interface that the current user wants to display on the display device 200 is a purchased interface, the server 400 can directly send the issued data to the display device 200, The off-shelf media assets in the distributed data are retained to display the off-shelf media assets in the purchased interface for users to click to play.

It can be seen from the above solution that the media asset data distribution method provided in the foregoing embodiment may extract and distribute data in response to the media asset request after obtaining the media asset request. The issued data includes the media assets purchased under the user information of the display device corresponding to the media asset acquisition request. Then filter the issued data according to the display interface type in the media asset request, that is, if the display interface type is the first type interface, delete the off-shelf media asset in the issued data, if the display interface type is the second type interface, keep it The off-shelf media assets in the data are issued to deliver the off-shelf media assets to the display device 200. The method can issue different media asset data for different display interfaces in the media asset request, so that different content can be displayed on the purchased interface and other interfaces.

For the server 400, the distributed media asset data may come from the database of the server 400 or a third-party database. As a media asset signal source, the number and types of media assets that can be issued by the server 400 are numerous. In order to know the extracted media assets in time, in some embodiments of the application, as shown in FIG. 19, according to the user The steps of information extraction and data distribution include:

S201B: Extract user information from the media asset request;

S202B: Grab all to-be-displayed media asset data under the user information according to the user information, and generate the issued data;

S203B: Traverse the online and offline status of each media asset to be displayed in the issued data;

S204B: If the online status of the media asset to be displayed is an offline status, mark the media asset corresponding to the media asset to be displayed as offline media asset.

In this embodiment, after the server 400 obtains the media asset request sent by the display device 200, it can extract the user information from the media asset request, and then match the media asset data from the database according to the user information, thereby capturing all pending information under the user information. Display media asset data and generate and distribute data.

By reading the online and offline status of each media asset to be displayed in the distributed data, it is determined which media asset is the off-shelf media asset. That is, if the online status (online) of the media asset to be displayed is offline, mark the media asset corresponding to the media asset to be displayed as offline media asset. Among them, the online and offline status is a status marking method determined according to preset rules, and can be comprehensively evaluated according to the storage status of the media assets in the database and/or the setting status in the operation activities.

Therefore, in some embodiments, as shown in FIG. 20, the step of traversing the online and offline status of each media asset to be displayed in the delivered data includes:

S231B: Obtain the media asset status of the media asset to be displayed;

S232B: If the operation online status, the third-party online status, and the sold-out status are all online statuses, set the online status of the media assets to be displayed to the online status;

S233B: If any one of the operational online/offline status, the third-party online/offline status, and the sold-out status is an offline state, set the online/offline status of the media asset to be displayed as an offline state.

In this embodiment, the media asset status of the media asset to be displayed may indicate the storage status of the media asset in the database, such as operational online status (available) and third-party online status (status); and the media asset to be displayed is in operation The setting status in the event, such as sold out status (shelves).

Among them, the operation online and offline status refers to the online and offline status of media assets maintained in the server 400, and is generally used to characterize the media assets created or purchased by the operating agency corresponding to the server 400 for copyright licenses. The operating online and offline status is usually modified by the server 400 according to operating rules. For example, when the copyright expires, it will be removed from the operating system of the server 400, thereby changing the operating online and offline status to offline.

The third-party offline status is the online status of media assets maintained by a third-party server, and is usually media assets with copyrights owned by an organization that has a cooperative relationship with the server 400. Therefore, the third-party offline status is usually modified by the third-party server in accordance with the cooperation regulations. For example, after the contract between the operating organization and the third-party organization expires, the server 400 will no longer be able to obtain the corresponding media assets from the third-party server, and the corresponding third-party online status is changed to offline.

The sold-out status is a media asset status that can be automatically changed according to the set start and end time of the event. Generally, when the sold-out status is online, it means that the corresponding media asset is still in the event period, and the user can purchase the corresponding media asset playback right at the price specified by the event. If the user purchases the right to play media assets, the media asset playback function can be used normally. When the sold-out status is offline, it means that the corresponding media asset is no longer in the event period, and the user can no longer purchase the corresponding media asset playback rights at the price specified in the event, but the media asset playback service is still running normally for users to choose to play.

In order to determine the online and offline status of the media assets to be displayed, the online and offline status can be determined according to the operational online and offline status, the third-party online and offline status, and the sold-out status. That is, if the operational online status, third-party online status, and sold-out status are all online statuses, set the online status of the media assets to be displayed as online status; if the operational online status, third-party online status, and third-party online status If any one of the online status and the sold out status is an offline status, then the online status of the media asset to be displayed is set as an offline status.

It can be seen that the media asset data distribution method provided in the foregoing embodiment can implement the control logic of whether the same media asset is issued on different interfaces. For example, the display device 200 may obtain the basic information of the course by calling the terminal-oriented system interface in the server 400. If the current interface is the purchased course interface, the media assets whose online status is offline can also be issued to display the purchased media assets in the purchased interface; for other interfaces, the media assets need to be uploaded and downloaded. Media assets whose online status is offline are filtered out.

In order to delete the off-shelf media assets in the distributed data, in some embodiments, as shown in FIG. 21, after the step of extracting the distributed data according to the user information, the method further includes:

S51B: Call the content system interface;

S52B: Set the entry parameters of the filtering module in the content system according to the display interface type.

Wherein, the step of setting the entry parameters of the filtering module in the content system according to the display interface type includes:

S521B: If the display interface type is the first type interface, set the entry parameter of the filtering module in the content system to true;

S522B: If the display interface type is the second type interface, set the entry parameter of the filtering module in the content system to false.

For the server 400, a terminal-oriented system interface and a content system interface can be further provided, and different processing modules can be activated by calling different interfaces. Among them, after calling the content system interface, the extracted data can be filtered through the filtering module in the content system. If the display interface type is the first type interface, it is determined that the off-shelf media assets in the issued data need to be deleted, so the filtering module can be started, that is, the entry parameter of the filtering module in the content system can be set to true. The filtering module can delete all media assets marked as offline in the distributed data during operation.

For example, the interface to be displayed by the display device 200 at startup is the home page interface. The data in the homepage interface is arranged in the background by the server 400. Therefore, the terminal-oriented system can obtain the arrangement data by querying the database, and then call the content system interface to obtain media asset details, including media asset posters, names, etc., and pass the input (filterOffline =true) Filter out the media assets whose online status is offline. At this time, the content system will only return the media assets whose online status is online. Finally, the terminal-oriented system encapsulates the delivered data after content filtering, and sends it to the display device 200 to form a homepage interface.

If the display interface type is the second type of interface, it is determined that there is no need to delete the off-shelf media assets in the issued data, so set the entry parameter of the filter module to false, that is, there is no need to process the issued data through the filter module, and directly The data is issued and sent to the display device 200.

For example, if the user has purchased media data, the terminal-oriented system first calls the member interface to obtain all courses that the currently logged-in user has purchased. Then call the content system interface to obtain the corresponding media asset details, but at this time the content system enters the parameter (filterOffline=false), that is, the content system is set not to filter online as offline media assets. Among them, if a certain course purchased by the user has been sold out (shelves=0), the online status of the course in the content system is the offline status (online=0), but because the entry parameter filterOffline=false is set, the content system is still Details of the course will be returned.

In addition, before sending the corresponding delivered data, the delivered data can be further filtered by judging the status of other types of media assets, so as to ensure that the media asset data sent to the display device 200 can be displayed normally. For example, in addition to obtaining the basic information of media assets, the terminal-oriented system also needs the content system to return the operational online and offline status available, the third-party online status status, and the sold out status to determine the online and offline status of the media asset online. That is to say, the terminal-oriented system will judge the media assets with the operational online status available = 1, the third-party online status status = 1, and the media assets with the sold-out status shelf = 0 for delivery.

In actual applications, after the delivered data is filtered in the above-mentioned embodiments, media data suitable for different display interface types can be obtained. That is, the method further includes: sending the off-shelf media assets to a display device. It can be seen that, compared to the traditional media data delivery method, the data that can be directly applied on the current display interface can be directly sent to the display device 200 without the need for the display device 200 to perform secondary screening of the data, so it can be adapted to a variety of display devices 200, and It can be directly run in a client application, and there is no need to perform large-scale functional configuration of the display device 200.

Based on the aforementioned media asset data distribution method, in some embodiments of the present application, a server 400 is further provided. The server 400 includes a terminal-oriented system and a content system, wherein the terminal-oriented system is configured to obtain a media asset request, The media asset request includes user information and a display interface type, and the display interface type is one of the first type of interface or the second type of interface; and, in response to the media asset request, the following is extracted according to the user information Sending data, where the issued data includes the purchased media assets under the user information.

The content system is configured to: if the display interface type is the first type interface, delete the off-shelf media assets in the issued data; if the display interface type is the second type interface, keep The off-shelf media assets in the distributed data.

The server provided in this embodiment can obtain the media asset request sent by the display device in real time through the terminal system after establishing a communication connection with the display device, and in response to the media asset request, extract and distribute data based on user information, thereby setting up the content system In the data filtering method, if the display interface type is the first type of interface, delete the off-list media assets in the issued data. If the display interface type is the second type of interface, keep the off-listed media assets in the issued data to remove The off-shelf media assets are delivered to the display device. The server delivers different media asset data for different display interfaces by executing the aforementioned media asset data distribution method, so that the data can still be fed back after the media asset is off the shelf, and the problem of display errors can be alleviated.

My application module management

For the "application" channel, after the user selects it, the icon and name of the application installed in the current display device can be displayed in the content area. The installed applications in the display device may include third-party applications of system applications. In order to adapt to the education mode, the installed applications can be filtered, and only education-related applications are displayed. For example, the application list displayed in the education mode can be configured remotely through the server, and then the installed applications can be matched with the application list one by one. If any installed application is in the application list, the application will be displayed in the content area.

In order to prevent users from misoperation, in the education mode, you can set the application to only support display and opening, and not support the update and uninstall of the application.

In some embodiments of this application, the arrangement of multiple application icons can also be set according to the size of the display interface, and multiple applications can be displayed by scrolling the page and/or adding a "All Application Entry" card . For example, as shown in Figure 22, there are 10 application display positions in the content area. When the number of applications that can be displayed is less than or equal to 10, the cards corresponding to all application entries may not be displayed; and when the number of applications that can be displayed When the number is greater than 10, 9 of them can be displayed. Other applications are categorized through the All Application Portal and displayed in the pop-up application interface after the user clicks the "All Application Portal" card.

The foregoing embodiment shows the display mode corresponding to the education mode after the navigation is turned on. In practical applications, you can also enter the education mode from the standard mode, and switch modes at will during operation.

In some embodiments, as shown in FIG. 29, in the application interface, the application installed in the display device 200 can be displayed, and the user can select in the application interface by controlling the device 100 or touching the touch screen. When any application is started, the current display screen jumps to the started application interface. Therefore, the application program interface can be used as the display interface of the application program and the unified start entry of the application program.

In the application program interface, each application program can be displayed in the form of icons and/or text, and multiple application program icons can be arranged according to specific rules to form an icon array. For example, system applications can be displayed first in the top area of the icon array, and third-party applications can be displayed in sequence according to the order of installation; the application icons can also be arranged according to the name, type or frequency of use of the application, or customized The order in which the application icons are arranged.

In some embodiments, the display device 200 may also filter the displayed application programs to adjust the content displayed in the application program interface according to different application scenarios. For example, you can set the applications that cannot be opened through the parental mode, so that in the parental mode, the application interface only displays the applications that can be opened, while other applications are hidden. Similarly, in the education mode, it is also possible to display only education-related applications, such as educational applications and some necessary system applications, while hiding other non-essential applications.

Wherein, the education mode is a special display mode preset relative to the standard mode. In the education mode, the UI style and interaction method of the operation interface can be different from the UI style and interaction method in the standard mode. Usually users can enter the education mode through the mode selection screen. For example, during the boot navigation process, select the education mode button on the mode selection interface to enter the education mode.

After entering the education mode, the display device 200 can present a control homepage in the education mode to the user, and the user can perform interactive operations on the control homepage to implement education-related functions. For example, you can click any course resource on the control homepage to play the course video. Users can also start a third-party application in the control homepage to obtain course resources through the third-party application.

In the education mode, the user usually does not use other applications other than the education application, so in order to facilitate the user to start, the display device 200 may only display part of the application in the application program interface, for example, as shown in FIG. 30, in the education mode The application interface of only displays educational applications.

In some embodiments, in the educational touch screen mode, the terminal will request the system to obtain the application list data that can be displayed. The terminal will obtain the locally installed application data and compare it according to the package name. If the locally installed application is in the displayable application In the list, it will be displayed in the terminal my application, otherwise it will not be displayed in my application. The displayable application list refers to a list of applications that can be displayed in the education mode, which may be preset by the user, or may be automatically determined by the terminal according to the label of the application. This can prevent applications that are not suitable for education from expanding during the learner's use. For example, the game 1 application is installed in the system and displayed in the standard mode. In the educational touch screen mode, it will not be displayed after being filtered by the displayable application list. .

In some embodiments, a preset number of applications are displayed in the education mode. When there are more applications that can be displayed, an "all application interface" for expanding the application list is added.

In some embodiments, application recommendations are made based on the applications associated with the displayed applications and displayed in the application interface. In some embodiments, they are displayed in a mixed arrangement with installed applications. For example, the installed application at the fourth position corresponds to a recommendable application, the recommended application corresponding to the installed application at the corresponding position 4 is displayed in the fifth position, and other applications are displayed in the sixth position.

In some embodiments, the recommended applications are displayed in the order of the installed applications in the application interface. When the number of recommended applications displayed exceeds a preset number (for example, when it exceeds 2), the installed applications at the lower position will not be displayed. Showcase of recommended apps.

In some embodiments, the recommended applications are displayed according to the comprehensive ranking of the installed applications in the user interface (for example, at least one parameter among hot searches, downloads, frequency of use, etc.), and the number of recommended applications displayed exceeds the preset number When (for example, when more than 2), the installed apps in the lower order will no longer be displayed as recommended apps.

Some embodiments of this application provide an application program interface display method. As shown in FIG. 31, the application program interface display method includes:

S1C: Obtain the control instructions used to display the application program interface.

In actual applications, the user can input control instructions to control the display device 200 to display the application program interface. The user can input control instructions in a variety of ways. For example, the user can select the label "application" in the switching area in the control homepage of the education mode to switch to the application program interface. The specific operation method may be: after entering the education mode homepage, using the arrow keys of the control device 100 to move the focus cursor to the "application" tab, at this time, the display device 200 can automatically switch the screen displayed in the content area to the application Program interface.

The user can also input control instructions for displaying the application program interface through touch operation or voice input. For example, the user clicks the “application” control in the control homepage through a touch operation, so that the content area of the control homepage of the display device 200 is switched to the application program interface. For another example, the user can input voice information through the intelligent voice system built into the display device 200, such as "display application" and "display application interface". After the display device 200 receives the voice information, it can switch the control homepage content area to the application program interface.

S2C: In the standard mode, in response to the control instruction, generate an application list in the application program interface according to all local applications;

After acquiring the control instruction input by the user, the controller 250 of the display device 200 may determine the current mode of the display device 200. If the current mode is the standard mode, in response to the control instruction, an application list of the application program interface is generated according to all local applications.

For example, when the user enters the "My Application" interface in the standard mode, it is equivalent to inputting a control instruction for displaying the application program interface. After receiving the control instruction, the controller 250 can determine the current mode of the display device 200, that is, determine that the current mode is the standard mode. At this time, the controller 250 can directly extract the locally installed application information, and extract the display content corresponding to all the local applications, thereby generating a display list of the application program interface to display all the local applications on the "My Application" interface.

Wherein, the application list in the application program interface may include information such as icons and names corresponding to the application programs to be displayed. After the controller 250 generates the application list, the specific display content in the application program interface may be generated according to the display program built in the operating system to be displayed in the application program interface.

In addition, when the controller 250 executes the display program, it can also perform unified optimization processing on the application program information to be displayed to obtain a better display effect. For example, the application icon is deformed, transparent, animated, rounded, etc., so that the style of the application icon displayed in the application interface tends to be unified, so as to bring a better display effect.

It can be seen that in the standard mode, the content displayed in the application program interface is all local applications, and there is no need to filter the displayed applications so that the user can perform routine operations in the application program interface. For example, when the user clicks any application icon, the application starts to run.

S3C: In the non-standard mode, in response to the control instruction, the application list in the application program interface is generated according to the local applications in the preset displayable application list.

After obtaining the control instruction input by the user, if it is determined that the mode of the current display device 200 is a non-standard mode through judgment, in response to the control instruction, the application in the application program interface is generated according to the local application in the preset displayable application list List, that is, display the local application after filtering the local application according to the preset displayable application list.

For example, when the user enters the "My Application" interface in the education mode, he enters a control instruction for displaying the application program interface. Since the current mode is an education mode, that is, a non-standard mode, it is necessary to filter the applications displayed in the application program interface, hide applications that are not related to the current education mode, and only display educational applications.

In order to filter the displayed local applications, after obtaining the control instruction, the preset displayable application list can be extracted first. Wherein, the preset displayable application list includes multiple preset displayable application information, which may be a general table uniformly produced by the operation server, or may be a list prepared by the display device 200 according to local applications. The displayable application list corresponds to the non-standard mode, that is, in different non-standard modes, the preset displayable application list is also different. For example, in the education mode, the preset displayable application list includes information related to education applications; in the parent mode, the preset displayable application list includes the displayable application information manually added by the parent; in the elderly mode, The preset displayable application list includes application information that can support the elderly display mode.

The preset displayable application list can be extracted from the local database of the display device 200 or from the database of the server 400. After extracting the preset displayable application list, the controller 250 can filter all the local applications installed in the display device 200 one by one according to the local applications in the preset displayable application list, thereby hiding applications that are not related to the current non-standard mode. Only show the apps in the preset to show the app list.

It can be seen that, according to the above-mentioned embodiment, the display device 200 and the application program interface display method provided by the present application can judge the current mode of the display device 200 after receiving the control instruction for displaying the application program interface, if it is the standard mode , Then all local applications are displayed; if it is in non-standard mode, the local applications are filtered according to the preset displayable application list, so that only the applications in the preset displayable application list are displayed. The method can display different application program interface contents in different modes, simplify the application program interface, and facilitate the user to find the application corresponding to the current mode in time.

In some embodiments, in order to filter the applications displayed in the application program interface, in the non-standard mode, the step of generating the application list in the application program interface according to the local applications in the preset displayable application list includes: responding to The control instruction is to obtain from the server a list of displayable applications corresponding to the current non-standard mode, and match the local application in the list of displayable applications according to the package name information, if the local application is matched in the list of displayable applications The package name information of the application is displayed in the application program interface, and if the package name information of the local application is not matched in the displayable application list, the local application is hidden.

In response to the control instruction, obtaining the displayable application list corresponding to the current non-standard mode from the server may be:

After acquiring the control instruction input by the user, the display device 200 may control the display to display the application program interface in response to the control instruction. In order to filter the displayed applications, after receiving the control instruction, the display device 200 may send a display request to the server 300 to obtain a list of displayable applications from the server 300.

The displayable application list is a real-time updateable list formulated by the server 300 for each application according to preset application classification rules. Since the application program interface can display different content in different display modes, it is necessary for the server 300 to set different application lists. For example, in the education mode, the acquired displayable application list may include information related to education applications, such as package name information.

The displayable application list may be formulated by the server 300 according to the information of each application registered in the application store. For example, a real-time updateable tabulation program can be built in the server 300, which can build an initial list for storing information of all educational applications registered in the current application store, and establish communication through the database corresponding to the application store Connect to obtain the data registered in the application store database in real time (or periodically), thereby updating the list of displayable applications. When a new educational application is registered in the application store, the new educational information can be added to the list of displayable applications.

The displayable application list may also be formulated by the server 300 according to the user setting information reported by the display device 200. For example, the user can customize the applications that can be displayed on the application program interface in the education mode through the display device 200, and send the customized setting information to the server 300 as user data, and the server 300 makes the settings according to the user setting information reported by the display device 200. Rules and filters applications in the application store to form a displayable application list and store it. When the display device 200 sends a display request, the stored displayable application list may be fed back to the display device 200.

In addition, the displayable application list can also be formulated and updated by combining the above two formulation methods. For example, when the display device 200 enters the education mode for the first time or the user does not customize the settings, the list of available applications is formulated according to the application information registered in the application store, and after the user-defined settings, the available applications are formulated according to the user-defined method. Show the list of applications.

Matching local applications in the displayable application list according to package name information may include:

After obtaining the displayable application list, the controller 250 of the display device 200 may match the local application in the displayable application list according to the package name information. In the actual matching process, the display device 200 may first extract the locally installed application data, and formulate a local application list according to the locally installed application data, and compare the local application list with the obtained displayable application list, so as to perform the local application filter.

In the actual matching process, the display device 200 can determine which application package name information in the local application list is in the displayable application list and which application package name information is not in the application list by comparing the local application list and the displayable application list. To obtain matching results. At the same time, through comparison, it can be determined that in the displayable application list, the package name information of which applications are not in the local application list can be used as recommended applications to facilitate users to download and install more types of educational applications.

Obviously, the process of matching local applications in the displayable application list is not limited to the above-mentioned matching method, and other matching methods can also be used according to the operating system types of different display devices 200. For example, after obtaining the list of displayable applications, the package name information of each local application can be used as an index value in turn to perform a traversal operation in the list of displayable applications to determine whether the package name information of the local application is in the list of displayable applications. If the package name information of the local application is the same as the information in any entry in the displayable application list, it is determined that the package name information of the local application is matched in the displayable application list.

If the package name information of the local application is matched in the displayable application list, displaying the local application in the application program interface may include:

By matching the local application in the displayable application list, it can be determined whether the local application is in the displayable application list, that is, the local application that can be started in the current display mode can be determined. If the package name information of the local application is matched in the displayable application list, it is determined that the corresponding local application can be started and run in the current mode, so the local application can be displayed in the application program interface.

By repeating the above matching process, until the package name information of all local applications is compared, the applications that can be displayed in the current display mode can be determined, so that all the applications that can be displayed are displayed in the application program interface. For users to choose.

It can be seen from the above technical solutions that the application program interface display method provided by the present application can be applied to the display device 200. After the user inputs a control instruction for displaying the application program interface, the displayable application list is obtained from the server 300, and the application program interface is displayed according to the package. The name information matches the local application in the displayable application list. If the package name information of the local application is matched in the displayable application list, the local application is displayed in the application program interface. The method can realize filtering of local applications in the education mode, so that only the applications related to the education mode are displayed in the application program interface in the education mode, which is convenient for users to start and run educational applications, and solves the needs of traditional smart TVs. It took a long time to find the problems of educational applications in many applications.

According to the above-mentioned embodiment, the local application whose package name information matches successfully can be displayed, while the local application whose package name information does not match successfully is not displayed in the application program interface. Therefore, in some embodiments, the application The program interface display method also includes:

If the package name information of the local application is not matched in the displayable application list, hiding the local application may include:

By hiding local applications that are not matched in the displayable application list, most non-educational applications can be hidden, so that the display device 200 displays a smaller number of applications in the application program interface in the education mode, and these applications are all Education-related applications, so that users can quickly find out which educational applications to start, and improve user experience.

For example, 30 application programs are installed in the display device 200, and 3 of them are educational applications. When the application program interface display method in the above embodiment is not used, the user needs to display 30 application programs in the application program interface. Find these 3 application icons in the icons. The user is required to press the arrow keys on the control device 100 multiple times to move the focus cursor to the icon of the educational application to be started. However, after the application interface display method in the above embodiment is adopted, since other applications other than the three educational applications are hidden, the user only needs to select the application to start from among the three educational applications, which greatly reduces This saves the workload when searching for applications, and simplifies the user's operation, so that the user can move the focus cursor to the corresponding position of the application by pressing the key three times at most, which also reduces the user's operational complexity.

Since the applications that can be displayed are different in different display modes, the filtering methods for local applications are also different. For example, in the education mode, the application program interface can display educational applications; in the parent mode, the application program interface can display applications specified by the user. Different display modes can be filtered by different displayable application lists. That is, in some embodiments, as shown in FIG. 32, the step of obtaining the displayable application list from the server 300 includes:

S211C: Send a display request to the server;

S212C: Receive the displayable application list fed back by the server.

After receiving the control instruction input by the user, the display device 200 may send a display request to the server 300 before displaying the application program interface. Wherein, the display request includes current scene information, such as scene number and other information. The scene number is character string information generated according to the preset rule number according to the scenes supported by the display device 200, for example, mode00 represents the standard mode; mode01 represents the education mode and so on.

After the display device 200 sends a display request with current scene information to the server 300, the server 300 may feed back a suitable displayable application list according to the current scene information, so that the display device 200 receives the displayable application list. For example, the display request sent by the display device 200 includes the current scene number as mode01, that is, the display device 200 is currently in the education mode. After the server 300 extracts the current scene number, it selects the displayable application list corresponding to the education mode from the stored displayable list, and feeds back the displayable application list to the display device 200.

It can be seen that the above feedback manner of the displayable application list can enable the server 300 to quickly feed back the displayable application list to the display device 200, reducing the waiting time for the user to enter the application program interface.

The displayable application list may also be an application list filtered by the server 300 according to the current scene information. That is, the server 300 may not store a large number of displayable application lists, but after the server 300 receives the display request, the list of applications from the application store All application information is extracted from the registration information, and the extracted application information is filtered according to the current scene number included in the display request, thereby generating a displayable application list. For example, if the display request sent by the display device 200 includes the current scene number as mode01, the server 300 first extracts all application information from the database of the application store, and then filters out educational applications from the extracted information, thereby generating a model that meets the educational model. The list of displayable applications is fed back to the display device 200.

It can be seen that this feedback method of displaying the application list does not need to occupy the storage space of the server 300 for a long time, and the server 300 does not need to maintain the displayable application list for a long time, thereby reducing the waste of the computing power of the server 300. In order to reduce the waiting time for entering the application program interface, it is also possible to send a display request to the server 300 when entering the display mode to obtain a list of displayable applications, and to filter the local applications through the background program so that the user can switch to the application program. When the interface is displayed, the screening results are directly displayed. At this time, the control instruction input by the user for displaying the application program interface may be the control instruction when the user selects the display mode.

According to the application interface display method provided in the above embodiment, after the local applications are filtered through the displayable application list, the number of applications that can be displayed in the application interface will generally be greatly reduced. If there are few displayable applications installed in the user display device 200, for example, a small number of educational applications, there are too few applications displayed in the screened application program interface, and a large area of display space will be wasted. In order to make full use of the display space, this part of the display space can also be used to display some recommended applications that conform to the current display mode without increasing the complexity of user operations.

Therefore, in some embodiments, the display request further includes user information, device information, and subscription information, and the application program interface display method further includes:

Obtaining a list of recommended applications from the server;

Adding a recommended logo to the application icon in the recommended application list;

The application icon with the recommended logo and the download link are displayed in the application program interface.

The recommended application list is an application list calculated by the server according to the user information, device information, and subscription information, and includes multiple application icons and download links corresponding to each application. In order to display the recommended application in the application program interface, the display device 200 can attach user information, device information, and subscription information to the display request sent. After receiving the display request, the server 300 can extract the user information and device information from the display request. And subscribe to the information, calculate and obtain the recommended application list according to the extracted information, and feed the recommended application list back to the display device 200.

After obtaining the recommended application list, the display device 200 may process the display pattern of the recommended application to distinguish it from other applications. For example, add a recommended logo to the application icon in the recommended application list. As shown in Figure 10, the recommendation logo can be added in the upper right corner area of the application icon and marked with the text "recommendation". Finally, the application icon with the recommended logo and the download link are displayed in the application program interface, so that the user can automatically download and install the recommended application after clicking the icon.

The above recommended applications are a type of applications that are not installed in local applications and conform to the current display mode, and are designed to provide users with more application download options that conform to the current scenario. For example, in the education mode, the recommended application may be an education application with a high download and installation volume in the application store. The recommended application may also be calculated and determined by the server 300 according to the user's behavior. For example, a recommendation model can be constructed in advance, and user information, device information, and subscription information are used as the input of the recommendation model, and the application name and recommendation degree value are used as the model output, so as to obtain a list of recommended applications.

The number of applications included in the recommended application list can be multiple, and multiple applications can be sorted according to a preset arrangement rule. For example, the recommended applications can be sorted according to the popularity of downloads in the application store; the recommended applications can also be sorted according to the recommendation degree value output by the recommendation model. Generally, the higher the recommendation degree value, the more suitable the recommended application is to the user's behavior characteristics.

Before the recommended application is displayed, the display position of the recommended application can also be set. The application icons to which the recommendation logo is added can be mixed and arranged with the application icons that can display the local applications in the application list. For example, the controller 250 runs the application shuffling algorithm to arrange the application display order. After determining 9 displayable applications, it is determined that two recommended applications can be displayed, and then the two recommended applications and 9 displayable applications are combined. Perform mixed arrangements to determine the display order of applications.

After determining the 9 displayable applications, you can first arrange the 9 displayable applications in a sequence, and determine whether it is necessary to display recommended applications. When there is no need to display recommended applications, such as turning off the "Guess you like" button, the 9 displayable applications will be directly displayed in the order in which they are arranged; and when recommended applications need to be displayed, two recommendations will be determined by calculation Applications, and then re-arrange the order of the 9 displayable applications and the two newly-added recommended applications that have already been arranged. When the arrangement is mixed, it can be randomly mixed, or spaced, or arranged according to the recommended display positions that have been configured for operation.

After the displayable local application icons and recommended application icons are mixedly arranged, the controller 250 may also display the mixedly arranged application icons in the application program interface. In order to display recommended applications without affecting the user's interactive operations, the number of applications displayed in the application program interface should not be too large, and the display position of the recommended applications should not affect the user's selection of local applications. Therefore, in some embodiments, a specific number of recommended applications may also be displayed in a specific display position, that is, the application program interface display method further includes: calculating according to the number of the local applications displayed in the application program interface The preset number. And, in the recommended application list, extracting application icons and their download links equal to the preset number. Exemplary:

Calculating the recommended display position according to the number of the local applications displayed in the application program interface;

In the recommended application list, extract application icons and download links that are equal to the number of recommended display positions;

The extracted application icon and download link are displayed on the recommended display position in the application program interface.

The display device 200 can extract the number of application programs that can be displayed in the application program interface, and then determine the number of application icons that can still be accommodated in the application program interface according to the number of displayable applications, thereby calculating the preset number. Then extract the corresponding number of applications from the recommended application list, so that the corresponding application icon and download link are displayed in the application program interface, and the corresponding download link is saved, so that when the user clicks the recommended application icon, the save can be called Download link data and visit the download link.

For example, in the education mode, the application program interface contains 12 display positions, that is, up to 12 application icons can be displayed. By filtering through the displayable application list, it is determined that the package name information of 9 local applications is in the displayable application list, and then 3 recommended display positions can be calculated. At the same time, the icons and download links of the first 3 applications are extracted from the recommended application list and displayed on the corresponding recommended display positions.

In actual applications, in order to obtain a better prompt effect, the recommended display position may be certain specific positions in the application list. For example, as shown in Figure 33, the 12 display positions can be divided into two rows for display. The second display position in each row is used as the recommended display position to display two of the recommended applications, and the other recommended application can be displayed in accordance with the local The order of the applications is displayed after the local application.

For the recommended application displayed in the application program interface, since it is not installed in the display device 200, it cannot be started and run directly. Instead, when the user clicks the application icon, the user can download the corresponding download link by visiting a specific download link. Recommended applications. Therefore, in some embodiments, the application program interface display method further includes:

Receive the selection instruction of the application control in the corresponding application list;

When the application control is a local application, in response to the selection instruction, open the corresponding local application;

When the application control is a recommended application, in response to the selection instruction, access the download link of the recommended application to obtain the installation file of the recommended application.

After displaying the application program interface, the display device 200 may also obtain a selection instruction of the application control in the application list. The selection instruction for the recommended application can be in the same interactive manner as the selection instruction for the local application, for example, after the focus cursor is positioned on the application icon by the control device 100, by pressing "OK/OK" on the control device 100 Key for input, also supports touch operation, such as clicking on the recommended application icon, and voice input, such as inputting "Open ××" to complete the input of the startup instruction.

After obtaining the selected instruction, the display device 200 may also perform different actions according to different types of current application controls. If the application control is a local application, the corresponding local application is directly opened in response to the selected instruction; if the application control is a recommended application, the download link of the recommended application is accessed in response to the selected instruction.

After obtaining the startup instruction, the display device 200 can obtain the installation file by accessing the download link of the corresponding recommended application. The download link may be a URL link provided by the application store system. When the display device 200 accesses the link, it can automatically obtain the application installation file from the server 300 side. After obtaining the installation file, the display device 200 can install the recommended application in the display device 200 by running the installation file.

After the application installation is completed, the display device 200 may display the installed application at a position corresponding to the display position of the original recommended application in the application program interface. After the recommended application has been installed, the recommended logo on the recommended application can be removed to mark the application as a local application.

It can be seen from the above technical solutions that, in the displayed application program interface in the above embodiment, when the user clicks an application that does not contain a recommended tag, the application is directly opened. When the user clicks on the application containing the recommended corner mark on the terminal, the corresponding download address URL is used to deliver the application, and the user is reminded to install it. After the installation is successful, the application is opened. Through the recommended application list obtained in the server 300, the recommended application is displayed on the application program interface, which helps the user to quickly obtain a type of application that conforms to the current display mode, thereby facilitating the enrichment of the user's resource selection in the current mode and improving the user Experience.

In some embodiments, as shown in FIG. 34, after the step of responding to the control instruction, the application program interface display method further includes:

S201C: Obtain the current display mode;

S202C: If the current display mode is the standard mode, display all the local applications in the application program interface;

S203C: If the current display mode is a non-standard mode, obtain a displayable application list from the server.

Wherein, the display mode is one of a standard mode or a non-standard mode. In practical applications, the standard mode is the normal viewing mode of the display device 200. When the application program interface is displayed in the standard mode, the application display situation in the application program interface may not be filtered. The non-standard mode is one or more display modes set according to a preset operation scheme. In the non-standard mode, part of the functions of the display device 200 will be restricted, so it is necessary to filter the application display in the application program interface.

Therefore, before displaying the application program interface, the current display mode can also be obtained first, and the application display mode in the application program interface can be determined according to the current display mode type. That is, if the current display mode is the standard mode, all local applications are displayed in the application program interface. If the current display mode is a non-standard mode, the displayable application list is obtained from the server 300, so as to filter the displayed applications through the displayable application list.

In some embodiments, since the display device 200 can switch between the standard mode and the non-standard mode, and the display layout of the application interface is different in different display modes, it is necessary to switch the display mode at the same time as specified The display layout of the application program interface displays the application program interface, and the application program interface display method further includes:

Receive a switching instruction input by the user for switching the display mode;

In response to the switching instruction, switching the current display mode includes:

If the current display mode is the standard mode, switch the display mode to the non-standard mode, and display the application program interface in the non-standard mode;

If the current display mode is non-standard mode, switch the display mode to standard mode, and display the application program interface in standard mode.

The switching instruction can be input by the user by pressing the "switch" button on the control device 100, can also be input by clicking the mode switching control on the control homepage, or can be input by voice "switching mode". After the switching instruction is input, the display device 200 can switch the current display mode to another display mode in response to the switching instruction.

For example, if the current display mode is the standard mode, after receiving the switching instruction, the standard mode can be switched to the non-standard mode to display the application interface in the non-standard mode; if the current display mode is the non-standard mode, then After receiving the switching instruction, the non-standard mode can be switched to the standard mode, thereby displaying the application program interface in the standard mode.

Based on the above application program interface display method, some embodiments of the present application also provide a display device 200, the display device 200 includes: a display, a communicator, and a controller. Among them, the display 275 is configured to display an application program interface; the communicator 220 is configured to perform data communication with the server 300.

The controller 250 is configured to execute the following program steps:

Obtain the control instruction input by the user for displaying the application program interface;

In response to the control instruction, obtain a list of displayable applications from the server;

Match the local application in the displayable application list according to the package name information;

If the package name information of the local application is matched in the displayable application list, the local application is displayed in the application program interface.

For the above-mentioned display device 200, the controller 250 may first determine the operation mode of the current display device after receiving the control instruction for displaying the application program interface. If it is the standard mode, in response to the control instruction, display in the application program interface An application list containing all local applications; if it is in a non-standard mode, it can respond to the control instruction and send a display request to the server 300 through the communicator 220. After receiving the display request, the server 300 can feed back the displayable application list and pass The network connection transmits the displayable application list, so that the controller 250 uses the communicator 220 to obtain the displayable application list from the server 300.

After obtaining the displayable application list, the controller 250 may execute the matching application to match the local applications installed in the display device 200 one by one in the displayable application list according to the package name information, so as to match the local applications in the displayable application list. When the package name information is displayed, the corresponding local application is displayed in the application program interface.

Based on the above-mentioned display device 200, some embodiments of the present application also provide a server 300 for feeding back a displayable application list and a recommended application list when receiving a display request sent by the display device 200. The server 300 includes: an operation subsystem, a recommendation subsystem, and an online subsystem. Among them, the operation subsystem is configured to generate a displayable application list; the recommendation subsystem is configured to generate a recommended application list;

The online subsystem is configured as:

Receive the display request sent by the display device;

In response to the display request, obtaining a list of displayable applications from the operation subsystem, and obtaining a list of recommended applications from the recommendation subsystem;

Send the displayable application list and the recommended application list to a display device.

After receiving the display request sent by the display device 200, the online subsystem may, in response to the display request, obtain the displayable application list from the operation subsystem and the recommended application list from the recommendation subsystem, respectively, and send the displayable application to the display device 200 A list and a recommended application list, so that the display device 200 can filter the application display conditions in the application interface according to the displayable application list and the recommended application list.

In some embodiments, the display request includes current scene information, and the online subsystem is further configured to:

Parsing the display request to obtain the current scene information;

Sending the current scene information to the operation subsystem;

Receive a displayable application list fed back by the operation subsystem, where the displayable application list is an application list generated by the operation subsystem through filtering according to the current scene information.

In some embodiments, the display request further includes user information, device information, and subscription information, and the online subsystem is further configured to:

Parsing the display request to obtain the user information, device information, and subscription information;

Sending the user information, device information, and subscription information to the recommendation subsystem;

A recommended application list fed back by the recommendation subsystem is received, where the recommended application list is an application list calculated and generated by the recommendation subsystem according to the user information, device information, and subscription information.

In actual applications, the controller 250 of the display device 200 may send a display request to the server 300, and the display request includes the scene number (Sence Code: My App), user information (customer Id), device information (device Id), and subscription information ( subscribeId) etc. The communicator 220 may pass the gateway and forward the request to the online subsystem. After receiving the request, the online subsystem can obtain the storage data in the operation subsystem database, and take out the package name (appPackageName) and download address URL in the storage data to obtain a list of displayable applications.

At the same time, the online subsystem also uses customerId, deviceId, and subscribeId as parameters to access the recommendation subsystem, so that the recommendation subsystem gets the request parameters, calculates the recommended application based on the user's behavior, and returns the package name of the recommended application (appPackageName) And download URL.

The online subsystem obtains the application package name from the recommendation subsystem and adds the field isRecommend to true. Add the field isRecommend to false for the application package name obtained by the operation subsystem, and deliver the combined data to the gateway to feed back to the display device 200 through the gateway.

After receiving the feedback data, the display device 200 traverses the returned data and processes each piece of data. If the package name package of a locally installed application is consistent with the current data, the application is displayed on the terminal interface. If there is no locally installed application whose package name package is consistent with the current data, judge whether isRecommend is true, if isRecommend is true, display this application to the interface, and add recommendations; if isRecommend is false, it will not display this application to interface.

It can be seen from the above technical solutions that the present application provides an application program interface display method, display device 200, and server 300. The method can be applied to the display device 200 to obtain the displayable application list from the server 300 after the user inputs a control instruction for displaying the application program interface, and match the local application in the displayable application list according to the package name information . If the package name information of the local application is matched in the displayable application list, the local application is displayed in the application program interface. The method can realize filtering of local applications in the education mode, so that only the applications related to the education mode are displayed in the application program interface in the education mode, which is convenient for users to start and run educational applications, and solves the needs of traditional smart TVs. It took a long time to find the problems of educational applications in many applications.

After the boot navigation is completed, the user can select the standard mode option in the display mode selection screen, that is, switch the focus mark to the standard mode option through the "left" key of the control device, and the background of the mode selection screen can be changed to the standard mode. The mode corresponds to the pattern and explanatory text, and then the standard mode option is selected through the control device "OK/OK" key to enter the standard mode.

After entering the standard mode, the control homepage corresponding to the standard mode will pop up on the display device. The standard mode homepage can include multiple display areas, such as the Header area, the switching area, and the content area.

As shown in Figure 23, the Header area can be set at the top of the entire display screen, including a variety of functional controls, such as: "search", "member", "message", "terminal connection status", "network connection status", "Weather", "time", etc. Each control can pop up the actual corresponding interface after clicking. For example, when the user clicks the "message" control, a message interface can pop up, and various messages published by the server or pushed by the application can be displayed in the message interface to form a message list. And, each message includes two states: read/unread. When there are unread messages in the message list, you can add prompt patterns on the "message" control.

Reissue of notification message

In some embodiments, the course notification message is sent by the server to the display device, but sometimes it appears that the server has completed sending the course notification message before the college customizes the course. For this reason, the inventor designed a message reissue mechanism. . Exemplary. After the timing task is completed, record the completion time. If a user purchases, BOS will notify the online subsystem through kafka, and the online subsystem will query whether there are eligible class hours under the course, and the class start time <(last class reminder message to notify the timing task execution time + 24 hours + 30 minutes) &&Class end time> current time; if there is, the class message will be pushed. If there is no push, it will not be pushed. The logic of its execution is shown in Figure 27.

The message reissue method provided in this application can be applied to a server, and the server is used to provide a variety of services for the display device. Generally, the display device can send various requests to the server, and the server can feed back corresponding data according to the request sent by the display device. A push message is a type of data uniformly sent by the server to multiple different display devices, and is usually used to transmit certain prompt information, such as media asset launch announcements, system prompts, and so on. Wherein, the display device refers to a device with an interface display function, such as a smart TV.

Based on the above-mentioned display device 200, the server 400 can push messages to the display device 200 by combining different application scenarios. The display device 200 can display the message pushed by the server 400. In order to display the pushed message, the controller 250 of the display device 200 may generate a message screen according to the received message, and control the display 275 to display the message screen.

The display device 200 can also adjust the display mode of the message screen according to the current usage scenario and the specific message content or type. For example, when the display device 200 controls usage scenarios such as homepage, education mode, etc., the push message may be a pop-up message box, displayed at the top or bottom of the display screen, and automatically disappear after a preset time of display to avoid viewing the user The experience makes an impact. When there are multiple push messages, each message screen can also be arranged according to the set arrangement. For example, as shown in FIG. 28, multiple message boxes may be displayed sequentially from top to bottom on the display screen according to the order in which the push messages are received.

In some embodiments, a message interface for displaying a message screen can also be set according to the message sending and receiving mode of the operating system of the display device 200. In the message interface, the push messages received by the display device 200 within a certain period of time can be displayed, so as to facilitate unified management of the messages. Messages can include read and unread status, and read and unread messages can be displayed in the message interface respectively.

In order to present the message interface, a unified message entry control may be provided on the part of the interface of the operating system of the display device 200. For example, there is a message entry control in the top status bar of the control homepage. When the user performs an interactive action and clicks on the message entry control, the user can jump to the message interface.

In some embodiments, push messages may include multiple types, such as system messages, third-party messages, and promotional messages. Different types of messages can be pushed by the server 400 in different situations. For example, system messages can be uniformly pushed by the server 400 for each terminal, and used to display system-level notification content, including firmware updates, patch upgrades, announcement notifications, and so on. The third-party message is usually generated by a third-party server of the application installed in the display device 200, and is directly pushed by the third-party server to the display device 200, or sent by the third-party server to the server 400 first, and then uniformly pushed to the server 400 through the server 400. Display device 200. The promotion message is generated by the server 400 according to the user's usage data, such as an application recommendation message calculated by counting data such as applications frequently run by the user. Promotion messages are also pushed to the display device 200 through the server 400, and usually include message content such as application recommendations, advertisements, and user-defined services.

The display form of the push message can also be adjusted according to the specific message content. For example, for system messages, pop-up messages can be used to reduce users’ missed important messages; for third-party application messages or promotional messages, they can be displayed in the form of message interfaces to reduce the frequency of message pushes and avoid distracting messages when displaying messages. The impact of user viewing experience.

In some embodiments of the present application, the push message has a time limit, that is, some prompt messages can be pushed in a specific time. In actual applications, the message push can be triggered by a timing task. For example, a timed task checks the class hours within half an hour after 24 hours, and then sends out a message notification, achieving the effect of reminding the user to attend the class 24 hours in advance.

Due to the influence of the trigger time, this type of timing task push method may miss messages. For example, the timed task pushes the class message only to users who have purchased the course 24 hours ago. Users who purchase the class after the timed task is processed will no longer receive reminders and miss the class message.

In order to alleviate the problem of missing messages in a timed task mode, the present application provides a method for re-sending a message. The method for re-sending a message includes the following steps:

Get notifications of user purchases. The user purchase notification includes user information and media asset ID.

Query the pre-push media assets according to the user information. A content system (module) dedicated to processing media asset data and related content data may be built in the server 400. The media asset data may be stored in the content system of the server 400 or in a database associated with the content system. After the server 400 obtains the user purchase notification, the user information in the user purchase notification may be extracted to query the pre-push media assets through the content system.

Extract the push message according to the media asset ID of the pre-push media asset.

Sending the push message to a display device corresponding to the user information.

Based on the foregoing predetermined judgment period, in some embodiments, before the step of obtaining a user purchase notification, the method further includes:

Obtain the recorded start time, completion time and execution time of each push task;

Calculate the time interval between the start time of the push task and the execution time of the previous push task, and generate a regular push cycle;

Calculate the time interval between the start time and the completion time of the push task, and generate a processing cycle.

In some embodiments, the step of querying pre-push media assets according to the user information includes:

Acquiring the preset judgment period and the current time;

Compare the media asset start time and the preset judgment period one by one;

If the media asset start time is within the preset judgment period, compare the media asset end time with the current time;

If the end time of the media asset is later than the current time, mark the media asset as a pre-push media asset.

In some embodiments, the logic of message reissuance can refer to the application filed on *month*, 2020, and the application number is: the Chinese patent application named ***.

The content area can occupy most of the area of the display screen, including the middle and bottom, so as to display resource cards, setting function cards and other content. Click on different cards to perform different functions. For example, function cards such as viewing history, my favorites, and resource cards composed of the cover of recommended resources can be displayed in the content area. You can also set up different video classification cards. In the video classification card, you can include multiple video resources of the same type. For example, animation house, English corner, picture book library, listening to the world, story meeting, science museum, etc. When there is a lot of content to be displayed in the content area, the content can also be displayed by scrolling the reel.

Multiple controls indicating different function pages can be set in the switching area, such as: "my", "channel", "movie", "VIP", "epidemic", "sports", "mall", "game", " "Apply", "Discover", etc. Different controls can display different content in the content area after being selected. For example, under the control corresponding to "Movies", the content area displays recommended resource cards, viewing history and other content.

Different from the control homepage in education mode, in standard mode, you can set the switching area between the header area and the content area, that is, set it below the header area and above the content area, so as to switch between different controls in the area To switch the content displayed in the content area. In the standard mode, the frequency of clicks on the controls in the switching area is higher than that in the education mode. Therefore, setting the switching area between the Header area and the content area can facilitate user operations.
