[0059] In some embodiments, the audio processor is configured to receive an external audio signal, and perform processing such as decompression and decoding, noise reduction, digital-to-analog conversion, and amplification processing, etc., according to a standard codec protocol of the input signal, to obtain a sound signal that can be played on a loudspeaker.

[0060] In some embodiments, the user can input a user command through a graphical user interface (GUI) displayed on the display 260, and the user input interface receives the user input command through the graphical user interface (GUI). Alternatively, the user can input a user command by inputting a specific sound or gesture, and the user input interface receives the user input command by recognizing the sound or gesture through a sensor.

[0061] In some embodiments, the "user interface" is a medium interface for interaction and information exchange between an application program or an operating system and a user, which realizes the conversion between the internal form of information and the form that the user can accept. The commonly used form of user interface is a graphical user interface (GUI), which refers to a user interface related to computer operation displayed in a graphical manner. It can be an icon, window, control, etc. interface element displayed in the display screen of an electronic device, wherein the control can include an icon, button, menu, tab, text box, dialog box, status bar, navigation bar, Widget, etc. visual interface element.

[0062] In some embodiments, the system of the display device can include a kernel, a shell, a file system and an application. The kernel, the shell and the file system together form a basic operating system structure, which allows a user to manage files, run programs and use the system. After power on, the kernel starts, activates the kernel space, abstracts hardware, initializes hardware parameters, etc., runs and maintains virtual memory, a scheduler, signals and inter-process communication (IPC). After the kernel starts, the shell and user applications are loaded. The application is compiled into machine code after starting, forming a process.

[0063] Referring to Figure 4 In some embodiments, the system is divided into four layers, from top to bottom, the application layer (referred to as "application layer" for short), the application framework layer (referred to as "framework layer" for short), the Android runtime and system library layer (referred to as "system runtime library layer" for short), and the kernel layer.

[0064] In some embodiments, at least one application program is running in the application layer, which can be a window program, a system setting program or a clock program provided by the operating system, etc.; or an application program developed by a third-party developer. In specific implementation, the application package in the application layer is not limited to the above examples.

[0065] The framework layer provides application programming interface (API) and programming framework for the application program. The application framework layer includes some pre-defined functions. The application framework layer is equivalent to a processing center, which decides the action of the application program in the application layer. The application program can access the resources in the system and obtain the services of the system through the API interface in execution.

[0066] As Figure 4As shown, the application framework layer in the embodiments of the present application includes managers (Managers), content providers (Content Provider), etc., wherein the managers include at least one of the following modules: an activity manager (ActivityManager) for interacting with all activities running in the system; a location manager (Location Manager) for providing access to system location services for system services or applications; a package manager (Package Manager) for retrieving various information related to application packages currently installed on the device; a notification manager (NotificationManager) for controlling the display and clearing of notification messages; and a window manager (Window Manager) for managing icons, windows, toolbars, wallpapers, and desktop components on the user interface.

[0067] In some embodiments, the activity manager is used to manage the life cycle of each application and the general navigation back function, such as controlling the exit, opening, back, etc. of the application. The window manager is used to manage all window programs, such as obtaining the size of the display screen, determining whether there is a status bar, locking the screen, intercepting the screen, controlling the display window change (such as reducing the display window, shaking the display, twisting the display, etc.), etc.

[0068] In some embodiments, the system runtime library layer provides support for the upper layer, i.e. the framework layer. When the framework layer is used, the Android operating system runs the C / C++ library contained in the system runtime library layer to realize the functions of the framework layer.

[0069] In some embodiments, the kernel layer is the layer between hardware and software. As Figure 4 As shown, the kernel layer includes at least one of the following drivers: an audio driver, a display driver, a Bluetooth driver, a camera driver, a WIFI driver, a USB driver, an HDMI driver, a sensor driver (such as a fingerprint sensor, a temperature sensor, a pressure sensor, etc.), and a power supply driver, etc.

[0070] In some embodiments, the hardware or software architecture can be based on the above-mentioned embodiments, and in some embodiments, it can be based on other similar hardware or software architectures, as long as the technical solutions of the present application can be realized.

[0071] Based on the display device 200, in the focusing process of the Android system, the display device 200 needs to collect all the focusable controls on the current user interface, that is, the entire user interface is traversed from the top layer, and all the focusable controls on each layer of the interface are searched. For a complex user interface, there are usually more than 30 focusable controls. After searching for the focusable controls, the distance between each focusable control and the current focus control needs to be compared and filtered to find the control closest to the current focus control. The process is complex and time-consuming. In order to improve the focusing speed, the display device and the focus management method are provided in some embodiments of the present application. It should be noted that the display device in the present application not only refers to a smart television, but also refers to a computer, a tablet computer, etc.

[0072] The process of focus management provided by the embodiments of the present application will be described below with reference to the accompanying drawings.

[0073] Figure 5 An exemplary flowchart of a focus management method according to some embodiments is shown in FIG. 1. The display device 200 provided in some embodiments of the present application includes a display 260 and a controller 250, which is in communication connection with the display 260. The display 260 is configured to display a user interface, and the controller is configured to perform the process of focus management in Figure 5 in combination with Figure 5 The process of focus management is as follows:

[0074] S501: receiving an input key instruction for controlling the focus movement.

[0075] In some embodiments, the display device 200 interacts with the user through the user interface presented by the display 206, for example, the display device 200 receives user control events through the user interface, such as searching for a movie to watch, searching for a history of watching records, etc. The control of the user interface in the display device 200 by the user cannot be separated from the control of the focus, that is, the user needs to control the focus to move to the target control by inputting the key instruction, and then control the focus control after the target control becomes the focus control, such as the user controlling the focus to move to the movie control on a certain movie recommendation position, and then the display device 200 starts playing the movie content corresponding to the movie control after the user continues to input the confirmation instruction.

[0076] In some embodiments, the user can input the key instruction to the display device 200 through the up / down / left / right direction keys on the remote controller, and the display device 200 controls the focus to move according to the direction indicated by the key instruction after receiving the key instruction. For example, the user inputs the down direction key on the remote controller, and the display device 200 controls the focus to move downward.

[0077] S502: obtaining a first display area where the current focus control is located, and adding a first control in the first display area to a candidate list as a candidate, wherein the first display area includes a plurality of controls that can obtain focus.

[0078] S503: adding a second display area to the candidate list as a candidate, wherein the user interface divides different levels based on a document object model, the first display area refers to a display area containing the current focus control, the second display area refers to a display area in the current user interface other than the first display area and adjacent to the first display area, and the second display area includes a plurality of controls that can obtain focus.

[0079] In some embodiments, in the bottom logic of the display device 200, the user interface divides different levels based on a document object model, so the display device 200 can divide different levels based on a document object model into different display areas.

[0080] Figure 6 The display effect schematic diagram of display area division in the main page according to some embodiments is exemplarily shown. As shown in Figure 6 In the main page of the display device 200, the header bar, the tab bar, the sidebar, and the content bar belong to different DOM layer structures respectively, so they can be divided into the header bar display area, the tab bar display area, the sidebar display area, and the content bar display area.

[0081] Figure 7 The display effect schematic diagram of display area division in the detail page according to some embodiments is exemplarily shown. As shown in Figure 7 After a user clicks on a certain media asset, the display device 200 displays the detail page as shown in Figure 7 In the detail page of the display device 200, the header bar, the detail page, and the recommendation page belong to different DOM layer structures respectively, so they can be divided into the header bar display area, the detail page display area, and the recommendation page display area.

[0082] In some embodiments, after the display device 200 receives a button command for controlling focus movement, it detects the display area where the currently focused control exists. The display area containing the currently focused control is considered the first display area, and the display area that does not contain the currently focused control and is adjacent to the first display area is considered the second display area. That is, within the current user interface, all display areas adjacent to the first display area are second display areas. It should be noted that, depending on the number of display areas contained in the current user interface, there may be one or more second display areas.

[0083] For example, in Figure 6 In the example, the current focus is on the "Recommended" control in the navigation bar, therefore the "Recommended" control is the currently focused control, the navigation bar display area containing the "Recommended" control is the first display area, and the top bar display area, sidebar display area, and content bar display area are all second display areas. For example, in... Figure 7 In the current context, the focus is on the "Media Asset Preview Window" control on the details page. Therefore, the "Media Asset Preview Window" control is the currently focused control, and the display area of ​​the details page where the "Media Asset Preview Window" control is located is the first display area. The top bar display area and the recommendation page display area are both the second display areas.

[0084] In some embodiments, the first display area includes a plurality of controls that can receive focus. The display device 200 adds all the first controls in the first display area as options to the candidate list, and adds the second display area as an entire area as an option to the candidate list.

[0085] For example, in Figure 6 In the example, the "My," "Channel," "AI Home," "Friends & Family," "Kids 6.1," "TV Series," "Movies," and "VIP" controls in the navigation bar display area are all added as options to the candidate list. The top bar display area, sidebar display area, and content bar display area are also added as options to the candidate list. For example, in... Figure 7 In the details page display area, the "text description" control, "full screen" control, "activate VIP" control, "favorite" control, and the control containing each episode in the series list are added as alternatives to the alternative list. The top bar display area and the recommendation page display area are also added as alternatives to the alternative list.

[0086] S504: Search for the nearest alternative to the current focus control in the alternative list according to the direction indicated by the key command, and make the alternative gain focus.

[0087] In some embodiments, the button command indicates the direction of focus movement that needs to be controlled. Focusing is performed according to the direction of focus movement indicated by the button command, that is, searching for the candidate option to which the focus needs to be moved in the candidate list. During focus searching, the nearest candidate option is searched in the candidate list.

[0088] like Figure 6 As shown, the current focus is on the "Recommended" control in the navigation bar display area. When the user presses the up arrow key via remote control, the display device 200 moves the focus to the top bar display area. When the user presses the down arrow key via remote control, the display device 200 moves the focus to the content bar display area. When the user presses the left or right arrow key via remote control, the display device 200 finds the "Kids 6.1" control and the "TV Series" control respectively in the navigation bar display area. Finally, the found alternatives gain focus. Here, gaining focus on an alternative means defocusing the previously focused control and drawing focus on the found alternative. Drawing focus means emphasizing the alternative by adding a border, bolding the font, or adding a background color.

[0089] In some embodiments, the options in the alternative list include a first control and a second display area.

[0090] In some embodiments, when the first control is found to be the closest alternative to the currently focused control according to the direction, the first control is controlled to acquire focus, so that the first control becomes the focused control. For example... Figure 7 As shown, the current focus is on the "Media Asset Preview Window". When the display device 200 receives the right directional key sent by the user via the remote control, it controls the removal of focus from the "Media Asset Preview Window" and finds the "Text Description" control in the details page display area. It then draws focus on the "Text Description" control to make it the focused control.

[0091] In some embodiments, when a second display area is found as the closest alternative to the current focused control according to the direction, a target control within the second display area is acquired, and the target control is controlled to acquire focus, so that the target control becomes the focused control. The target control refers to the control within the second display area that needs to be focused. That is, when a second display area is found as the closest alternative to the current focused control, the display device 200 immediately searches for a target control within the second display area and controls the target control to become the focused control.

[0092] In some embodiments, when the display device 200 is searching for the target control, the display device 200 first controls the second display region closest to the current focus control to obtain the focus, so that the second display region becomes the focus display region; then the display device 200 searches for the target control in the focus display region and controls the target control to obtain the focus. As shown in FIG. 21, the current focus is on the "media preview window", and when the display device 200 receives the down direction key sent by the user through the remote controller, the display device 200 controls the focus to jump to the recommended page display region, so that the recommended page display region becomes the focus display region, and then the display device 200 searches for the target control from the recommended page display region. Figure 7

[0093] In some embodiments, when the display device 200 controls the focus to move, if the focus is controlled to jump from one display region to another display region, the display device 200 needs to record the last control on which the focus stays before the focus moves to the next display region. In some embodiments, the display device 200 can record the last control on which the focus stays in the display region in the form of a key value. For example, HEADER_FOCUS_VIEW: "search", TAB_FOCUS_VIEW: "recommend", and the subsequent HEADER_FOCUS_VIEW and TAB_FOCUS_VIEW key values can be used to quickly find the last focus control existing in the display region. Here, the last control on which the focus stays before the focus moves to the next display region is referred to as the second control.

[0094] In some embodiments, the display device 200 searching for the target control in the second display region includes the display device 200 detecting whether the second control that has been a focus control exists in the focus display region. If the second control exists in the focus display region, the display device 200 further needs to detect whether the state of the second control is normal. If the second control still exists on the user interface, the state of the second control is normal, and if the second control does not exist on the user interface, the state of the second control is abnormal.

[0095] In some embodiments, if the second control exists in the focus display region and the state of the second control is normal, the second control is regarded as the target control, the focus is controlled to move to the second control, and the second control becomes the focus control. If the second control exists in the focus display region and the state of the second control is abnormal, or the second control does not exist in the focus display region, the head control or the tail control of the focus display region is regarded as the target control, the focus is controlled to move to the head control or the tail control of the focus display region, and the head control or the tail control becomes the focus control. Thus, the display device 200 can continue to control the moving direction of the focus according to the key instruction continuously input by the user, and select the control that the user wants to manipulate in the second display region.​

[0096] The above focus management process will be further explained below with reference to the accompanying diagram.

[0097] Figure 8 The diagram illustrates another flow chart of a focus management method according to some embodiments. Figure 8 As shown, the display device 200 receives a key command and initiates a focus-finding process upon receiving the command. During the focus-finding process, the display device 200 collects alternative options into a candidate list by region. The display device 200 determines whether the currently focused control is within the display area. If the currently focused control is not present in the display area and the display area is adjacent to the display area containing the currently focused control, the entire display area is added to the candidate list as an alternative. If the currently focused control is present in the display area, all controls within the display area are added to the candidate list as alternatives. The display device 200 searches for the alternative closest to the currently focused control in the direction indicated by the key command. If the alternative closest to the currently focused control is a specific control, the focus is moved to that control. If the alternative closest to the currently focused control is a display area, the focus is moved to that display area. Within the focused display area, the display device 200 further searches for the target control. If a previously focused control exists in the focused display area and is in a normal state, it is considered the target control, and the focus is directly moved to that control. If there is no previously focused control in the focused display area, the control at the beginning or end of the focused display area is considered the target control, and the focus is moved to the control at the beginning or end of the focused display area. At this point, the button handling process ends.

[0098] The display device in this application divides the user interface into different display areas. During focus searching, for the display area with current focus, all controls within it are candidate options; for the display area without current focus, the entire display area is considered a candidate option. For the display area without current focus, there is no need to traverse all controls within it, thus avoiding the process of traversing all controls on the user interface during focus searching, and consequently omitting the process of acquiring the target control, greatly improving the speed of the focus searching process.

[0099] Based on the same inventive concept as the display device described above, the embodiment of the present application further provides a focus management method, which comprises: a display device 200 receiving a key instruction input by a user for controlling focus movement. The display device 200 controls a user interface to divide different levels into different display areas based on a document object model, wherein the first display area refers to a display area containing a current focus control, the second display area refers to a display area in the current user interface except the first display area and adjacent to the first display area, and the first display area and the second display area each include a plurality of controls that can obtain focus. The display device 200 obtains the first display area where the current focus control is located, adds a first control in the first display area as an alternative to an alternative list, and adds a second display area as an alternative to the alternative list. The display device 200 finds an alternative closest to the current focus control in the alternative list according to a direction indicated by the key instruction, and makes the alternative obtain focus.

[0100] In some embodiments, the finding of the alternative closest to the current focus control in the alternative list according to the direction indicated by the key instruction and the making of the alternative obtain focus comprises: when the alternative is the first control, the display device 200 controls the focus to move to the first control, so that the first control becomes the focus control. When the alternative is the second display area, the display device 200 obtains a target control in the second display area, controls the target control to obtain focus, so that the target control becomes the focus control, wherein the target control refers to a control to be focused in the second display area.

[0101] In some embodiments, when the alternative is the second display area, the obtaining of the target control in the second display area and the controlling of the target control to obtain focus comprises: the display device 200 controls the second display area to obtain focus, so that the second display area becomes a focus display area. The display device 200 finds a target control in the focus display area, and controls the target control to obtain focus.

[0102] In some embodiments, the searching for the target control in the focused display area includes: the display device 200 detecting whether a second control that is a focused control exists in the focused display area. If the second control exists in the focused display area and the state of the second control is normal, the display device 200 controls the focus to move to the second control, so that the second control becomes the focused control. If the second control exists in the focused display area and the state of the second control is abnormal, or the second control does not exist in the focused display area, the display device 200 controls the focus to move to a head control or a tail control of the focused display area, so that the head control or the tail control becomes the focused control.

[0103] Since the above embodiments are described in combination with other manners, and different embodiments have the same parts, the same and similar parts between various embodiments in the description are referred to each other, which will not be described in detail here.
