In some embodiments, the activity manager is to: managing the life cycle of each application program and the general navigation backspacing function, such as controlling the exit of the application program (including switching the user interface currently displayed in the display window to the system desktop), opening, backing (including switching the user interface currently displayed in the display window to the previous user interface of the user interface currently displayed), and the like.

In some embodiments, the window manager is used to manage all window processes, such as obtaining display size, determining if there is a status bar, locking the screen, intercepting the screen, controlling display window changes (e.g., zooming out, dithering, distorting, etc.) and the like.

In some embodiments, the system runtime layer provides support for the upper layer, i.e., the framework layer, and when the framework layer is accessed, the android operating system runs the C/C + + library included in the system runtime layer to implement the functions to be implemented by the framework layer.

In some embodiments, the kernel layer is a layer between hardware and software. As shown in fig. 4, the core layer includes at least one of the following drivers: audio drive, display drive, bluetooth drive, camera drive, WIFI drive, USB drive, HDMI drive, sensor drive (such as fingerprint sensor, temperature sensor, touch sensor, pressure sensor, etc.), and so on.

In some embodiments, the kernel layer further comprises a power driver module for power management.

In some embodiments, software programs and/or modules corresponding to the software architecture of fig. 4 are stored in the first memory or the second memory shown in fig. 2 or 3.

In some embodiments, taking the magic mirror application (photographing application) as an example, when the remote control receiving device receives a remote control input operation, a corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the input operation into an original input event (including information such as a value of the input operation, a timestamp of the input operation, etc.). The raw input events are stored at the kernel layer. The application program framework layer obtains an original input event from the kernel layer, identifies a control corresponding to the input event according to the current position of the focus and uses the input operation as a confirmation operation, the control corresponding to the confirmation operation is a control of a magic mirror application icon, the magic mirror application calls an interface of the application framework layer to start the magic mirror application, and then the kernel layer is called to start a camera driver, so that a static image or a video is captured through the camera.

In some embodiments, for a display device with a touch function, taking a split screen operation as an example, the display device receives an input operation (such as a split screen operation) applied to a display by a user, and the kernel layer may generate a corresponding input event according to the input operation and report the event to the application framework layer. The window mode (such as multi-window mode) corresponding to the input operation, the position and size of the window and the like are set by an activity manager of the application framework layer. And the window management of the application program framework layer draws a window according to the setting of the activity manager, then sends the drawn window data to the display driver of the kernel layer, and the display driver displays the corresponding application interface in different display areas of the display.

In some embodiments, as shown in fig. 5, the application layer containing at least one application may display a corresponding icon control in the display, such as: a live television application icon control, a Video On Demand (VOD) application icon control, a media center application icon control, an application center icon control, a game application icon control, and the like.

In some embodiments, the live television application may provide live television via different signal sources. For example, a live television application may access input providing television signals from cable television, radio broadcasts, satellite services, or other types of live television services. And, the live television application may display video of the live television signal on the display device 200.

In some embodiments, a video-on-demand application may provide video from different storage sources. Unlike live television applications, video on demand provides a video display from some storage source. For example, the video on demand may come from a server side of the cloud storage, from a local hard disk storage containing stored video programs.

In some embodiments, the media center application may provide various applications for multimedia content playback. For example, a media center, which may be other than live television or video on demand, may provide services that a user may access to various images or audio through a media center application.

In some embodiments, an application center may provide storage for various applications. The application may be a game, an application, or some other application associated with a computer system or other device that may be run on the smart television. The application center may obtain these applications from different sources, store them in local storage, and then be operable on the display device 200.

The above embodiments describe the hardware/software architecture and functional implementation of the display device. In some application scenarios, the display device has a built-in search application, which is generally a default search application in the homepage, and may further install a third-party search application, such as google, hundredth, Youtube, amazon, and the like, and the built-in search application of the display device has a large search range and may relate to media asset data of multiple third-party platforms, so that the search result generally presented to the user by the built-in search application is a media asset set of multiple third-party search applications.

In some embodiments, the display device is generally provided with a home page in which some entrances for resources, operations and applications are provided, and fig. 6 illustrates a home page of the display device 200, and the upper part of the home page includes blocks of media asset search, application store, application center and viewing history. Some recommended videos, such as the hottest videos, the latest videos and the like, can be displayed in the middle of the home page, and the videos are pushed to the user, so that the user can conveniently and quickly enter videos which may be interested. The lower part of the homepage may include some theme tiles such as drama, movie, anarchy, game, music, media cloud, etc.

In one application scenario, when a user clicks "media asset search" while browsing a homepage, the built-in search application of the display device is started, and the search page shown in fig. 7 is skipped to, where the search page includes an input field and a search control. And clicking the input field by the user to enable the cursor to flash in the input field, namely starting to input keyword information, and clicking the search control after the keyword information is input, so as to start a media resource search process of the display equipment.

In some embodiments, the user may input keyword information by operating an electronic keyboard through an input device such as the remote control 100A or a mouse; or inputting keyword information through a physical keyboard; alternatively, the keyword information input by the user in the form of voice may be collected by the sound collector 231, and the input method of the keyword information is not limited. The keyword information inputted by the user is displayed on the input field simultaneously, and the cursor is moved as the characters are continuously inputted.

Different language input methods can be adopted to input keyword information, so that the method is suitable for different countries and language use environments. In the example of the search page in fig. 7, the keyword information is "Youtube divider amazon" and the language is english, each character in the keyword information may be in upper case or lower case, and when a plurality of keyword words need to be input, adjacent words may be separated by typing a space. The keyword information includes 3 words, which are "Youtube", "spider", and "amazon", respectively. "Youtube" and "amazon" are obviously english names of third-party applications, and therefore can be recognized as application identifiers, where the application identifiers may be full names, short names, or other preset representation forms of search applications, and the application identifiers have global uniqueness, that is, the search applications and the application identifiers thereof are in one-to-one correspondence. The search term in the keyword information input by the user is necessary, and is used for screening and searching the corresponding matched media asset data, and in fig. 7, the media asset data containing or related to the word "spider" is obtained. When the keyword information is recognized, all the included words are distinguished according to the partition of the space character, and then application marks in all the words are recognized, so that other words are recognized as search words.

In some embodiments, one or more application identifications may be included in the keyword information. When the application identifier is included, the search application corresponding to the application identifier is the independent target search application, and the target search application is directly controlled to retrieve the media asset data. For example, if the keyword information is 'google at Christmas day', the 'google' is identified as the only contained application identifier, and the 'Christmas day' is a search word, the user jumps to the google application to search the media data matched with the Christmas day.

In some embodiments, when the keyword information includes a plurality of application identifiers, it is described that two or more search applications are involved to retrieve the asset data, and in order to improve the search efficiency, one of the application identifiers may be preferred as a target search application, taking the keyword information "Youtube divider amazon" as an example, fig. 8 shows an example of displaying an application list popup window on an upper layer of a search page, and after an operation guidance information, such as "please select a target search application of a third party", is displayed above the application list popup window, a user may select one of the application identifiers listed below as the target search application after seeing the operation guidance information; a plurality of application identifiers and first controls included in the keyword information may be sequentially displayed below the operation guidance information, a first row in fig. 8 illustrates an application identifier "YouTube", a second row illustrates an application identifier "Amazon", and a third row illustrates a first control, and the first control may be, for example, in a form of "no-jump third-party search application".

If the user clicks 'YouTube' or 'Amazon', the fact that the user needs to jump to the third-party search application to retrieve the media asset data is indicated, the user selects a selected application identifier to be a target application identifier, the application corresponding to the target application identifier is the target search application, and the user jumps to the target search application to retrieve and display the media asset data.

In some embodiments, as shown in fig. 9, when a user selects "YouTube" in an application list popup, the YouTube application becomes a target search application, and after the user jumps into the YouTube application, the YouTube application displays the retrieved media asset data in an application interface according to a search term "SPIDER", where the media asset data is a video resource related to the form of "SPIDER", or "SPIDER", that is, a difference in character case between a keyword carried in the searched media asset data and the search term may be allowed, for example, each piece of media asset data is displayed in a row below the interface of fig. 9, the user may switch the media asset data by a left key or a right key, and when a certain piece of media asset data is in a focus, the user clicks a confirmation key, that is, the user may jump to a page to play a media asset video. The media asset data displayed for the user to view in the interface may specifically include content such as a thumbnail, a video name, a video size, and a publishing time, which is not limited in the present application. The target search application of the third party can also comprise an electronic keyboard which supports the input of characters such as letters, numbers, symbols and the like, and a user can conveniently operate the electronic keyboard at any time to modify the search terms, so that the media asset data is changed.

In some embodiments, when the user inputs a character in the upper left-hand input field in fig. 9, some search terms similar to the currently input character/character string may be pushed below the input field, for example, when "spider" is input, search terms such as "spiderman", "spider man cart on", "spider man song" and the like may be pushed below the input field, and if there is a target that the user desires to input in the pushed search terms, the pushed search terms may be directly clicked without inputting a complete search term in the input field, thereby improving search efficiency and user experience.

In some embodiments, if the user clicks the first control, it is indicated that the user does not want to search the media asset data using the search application of the third party, a conventional search process is performed, the built-in search application of the display device is controlled to retrieve by using the keyword information, media asset sets of the plurality of search applications are obtained, and the media asset sets are displayed in a page of the built-in search application. As shown in fig. 10, a Search result (Search Results for 'divider') of the built-in Search application with the term "divider" is shown, and the built-in Search application can perform classified display on the Search result, for example, a first type of display MOVIE (MOVIE) type media data related to the "divider" and mark a Search source of such media data, for example, video MOVIE provider & & Amazon, indicating that the divider MOVIE media data is from Amazon; the second category exposes Television (TV) -type asset data related to "spiders" and labels the search sources of such asset data, such as video TV provider & & Amazon, indicating that spider television assets are from Amazon. Or, the media asset set can be displayed in a mixed mode; or, performing classified display according to the third-party search application, for example, summarizing the spider media data from Amazon to one plate region display, summarizing the spider media data from YouTube to another plate region display, and the like. It should be noted that, after the media asset collection is obtained, the built-in search application may present each item of media asset data in different forms or classification categories, and is not limited to the example of this embodiment and fig. 10.

In some embodiments, after the user clicks the target application identifier or the first control in the application list popup, the application list popup is automatically hidden and the user jumps to the page corresponding to the search result.

In some embodiments, when the user inputs keyword information in the page of fig. 7, if the user does not want to specify a specific third-party search application, and may not input an application identifier, the keyword information only includes a search term without any application identifier, in which case a conventional search process is performed, the built-in search application controlling the display device performs a search using the keyword information to obtain media asset sets of a plurality of search applications, and displays the media asset sets in the page of the built-in search application. The present embodiment is similar to the search process and the page display when the first control is triggered, and details are not repeated here.

The UI interface diagram provided by the application is only exemplary, UI display, jump and change can be set adaptively on the basis of the search mechanism, and the method is based on practical application.

Under a conventional search process, a media asset set comprising media asset data of a plurality of third-party search applications can be retrieved according to a retrieval word input by a user, so that the data volume contained in the media asset set is large, the data volume capable of being displayed in a page displaying a search result is limited, on one hand, more or even complete media asset data cannot be displayed for the user, on the other hand, the data volume is large, the time consumption for the user to find the intended media asset is long, the efficiency is low, and therefore the search function of the display device cannot provide better use experience for the user.

Based on this, in some embodiments, as shown in fig. 11, there is provided a search method configured to be executed by the controller 250 in the display device, i.e. the controller 250 is the execution subject of the method, the method comprising the following program steps:

step S10, in response to receiving the keyword information input by the user in the search page, identifying the keyword information.

The keyword identification information is mainly used for identifying the application identification and the search term contained in the keyword identification information, positioning and skipping of third-party search application are carried out by using the application identification, and matched media asset data are searched by using the search term.

In some embodiments implementing step S10, if a space character is identified in the keyword information, the keyword information is divided into a plurality of keywords by using the space character, for example, the keyword information is "NBA Kobe goole", two space characters can be identified in the information, so that the keyword information is divided into 3 keywords, respectively, "NBA", "Kobe" and "goole", and there is a "logical and" relationship between the keywords in the keyword information, that is, the finally searched media asset data is to be matched with all keywords; and then matching each keyword with an application identifier library, wherein the application identifier library stores application identifiers of third-party applications which are installed on a display device and support a search function, the application identifiers can be full names, short names, abbreviations or other preset identification forms of the applications, and can also store application identifiers in different languages so as to improve the identification accuracy, if the application identifiers are English identifiers, the letters can be identified in case of capital and small cases, for example, google/Goole corresponds to the same third-party search application.

For each keyword, if the keyword is included in the application identification library, the keyword belongs to an application identification, such as "goole"; if the keyword is not included in the application identifier library, the keyword is determined to belong to a search term, and the search term is used for screening and matching media asset data during searching, such as "NBA" and "Kobe" are the search terms identified in the keyword information.

In some embodiments, the application identifier library may be updated according to the usage status of the third-party search application, for example, when a certain third-party search application is uninstalled, the application identifier of the third-party search application is deleted from the library; or if a third-party search application is newly added to the display device, after the third-party search application is successfully installed, the application identifier is stored and put in a storage, so that the application identifier library is dynamically updated, the accuracy of identification of the application identifier in the keyword information is ensured, and false identification and missing identification are avoided.

In some embodiments, when identifying keyword information for search matching, different matching modes, such as exact matching and fuzzy matching, may also be set according to the matching degree requirement. The precise matching can be used for strictly matching the space character and the case of each character with high precision, the retrieved media asset data is more precise, but the filtering degree is high, and the data volume is possibly relatively less; the fuzzy matching does not match the space character and the case of each character, the matching degree of the retrieved media asset data is relatively low, but the filtering degree is low, and the data volume available for browsing is relatively richer. The user can select whether to adopt the precise matching or the fuzzy matching according to the requirement on the matching degree/data quantity of the media asset data.

And step S20, when the keyword information is identified to contain the application identification, controlling the target search application to retrieve the media asset data matched with the keyword information, and controlling the display to display the media asset data in the page of the target search application. Step S20 corresponds to the case where the application identifier is identified in the keyword information, and may specifically include the following three cases (a) to (C):

(A) and if the keyword information only contains one application identifier, directly controlling the target search application corresponding to the application identifier to retrieve the media asset data, and displaying the media asset data searched according to the search terms in the page of the target search application to a user for browsing.

(B) When the keyword information is recognized to include a plurality of application identifiers, that is, when more than one application identifier is recognized, the display 275 is controlled to display an application list popup, as shown in fig. 8, names and first controls of all recognized third-party search applications may be displayed in the application list popup, each name corresponds to one third-party search application, and when the first control is triggered, a conventional search process is executed without jumping to the third-party search application to retrieve media data. When the controller 250 responds to the received selection operation of the target application identifier in the application list popup, the target search application corresponding to the target application identifier is controlled to retrieve the media asset data, namely, one of the identified third party search applications is selected as the target search application, so that the targeting, efficiency and accuracy of media asset search are improved.

(C) Recognizing that the keyword information contains a plurality of application identifiers, controlling the display 275 to display an application list popup, and clicking a first control in the popup if a user does not want to jump to a third-party search application to search media resources after seeing the application list popup. In response to receiving the click operation on the first control, the controller 250 executes a conventional search process, controls the built-in search application to retrieve according to the keyword information to obtain media asset sets of a plurality of search applications, and controls the display 275 to display the obtained media asset sets in the page of the built-in search application. For example, the keyword information is "Youtube divider amazon", which includes two application identifications "Youtube" and "amazon", and the search term is "divider" (spider), then the asset set includes all the asset data related to the spider in the platform of oil tube and amazon, and the asset set is displayed to the user in the page (refer to fig. 10) of the built-in search application, which is convenient for the user to browse and find the intended asset. All the asset data in the asset set may be displayed together in a centralized manner, or may be displayed in a classified manner according to the application identifier.

In some embodiments, the user may only input the search term without inputting any application identifier, that is, corresponding to the case where no application identifier is identified in the keyword information, similar to the case of (C) described above, it is necessary to control the built-in search application to perform the search according to the keyword information, obtain the sets of media assets of the plurality of search applications, and control the display 275 to display the obtained sets of media assets in the page of the built-in search application. Unlike the case (C), since the keyword information does not include any application identifier, the amount of data included in the search result is larger, and the media asset set may include media asset data of all third party search applications in the application identifier library, which matches with the search term, relatively speaking, although it can provide a more comprehensive media asset for the user to traverse each third party platform, the efficiency of the user to find the intended media asset is lower.

As shown in fig. 12, another embodiment of a search method is provided, comprising:

step S101, receiving keyword information input by a user in a search page or input by voice;

step S102, identifying whether the keyword information contains an application identifier; if yes, executing step S103, otherwise executing step S107;

step S103, whether the number of the application identifications is greater than 1; if yes, executing step S104, otherwise executing step S106;

step S104, controlling a display to display an application list popup;

step S105, whether a click operation on the first control is received or not; if not, the step S106 is executed if the user selects to click the target application identifier; otherwise, if the user clicks the first control, executing step S107;

step S106, controlling the target search application to retrieve and display the media asset data;

and S107, controlling the built-in search application to retrieve and display the obtained media asset set.

According to the technical scheme, a user can input keyword information in a search page, the keyword information can comprise a search term and an application identifier, the search term is used for screening matched media asset data, the application identifier is used for referring to a target search application from which the media asset data comes, then the controller identifies the keyword information, and a corresponding search process is executed according to whether the keyword information contains the application identifier and the number of the application identifiers. Once the keyword information is identified to contain the application identifier, the target search application can be started to retrieve the media asset data, and the search result is displayed in the page of the target search application, so that the media asset search has more platform targeting. According to the scheme, a large amount of unmatched media asset data can be filtered, matched media asset data in third-party search application appointed by the user can be quickly searched, the efficiency of searching intention media assets by the user and the accuracy of a search function are improved, and the user experience is improved.
