In some embodiments, as shown in fig. 4, the system is divided into four layers, from top to bottom, an application layer (abbreviated as "application layer"), an application framework layer (abbreviated as "framework layer"), a An Zhuoyun row (Android run) and a system library layer (abbreviated as "system runtime layer"), and a kernel layer.
In some embodiments, at least one application program is running in the application program layer, and these application programs may be a Window (Window) program of an operating system, a system setting program, a clock program, or the like; or may be an application developed by a third party developer. In particular implementations, the application packages in the application layer are not limited to the above examples.
The framework layer provides an Application Programming Interface (API) and programming framework for the application. The application framework layer includes a number of predefined functions. The application framework layer corresponds to a processing center that decides to let the applications in the application layer act. Through the API interface, the application program can access the resources in the system and acquire the services of the system in the execution.
As shown in fig. 4, the application framework layer in the embodiment of the present application includes a manager (manager), a content provider (ContentProvider), and the like, where the manager includes at least one of the following modules: an activity manager (actigamag) is used to interact with all the activities that are running in the system; a location manager (LocationManager) for providing access to system services or applications for system location services; a package manager (PackageManager) for retrieving various information about an application package currently installed on the device; a notification manager (notifinmanager) for controlling display and clearing of notification messages; a window manager (WindowManager) is used to manage bracketing icons, windows, toolbars, wallpaper, and desktop components on the user interface.
In some embodiments, the activity manager is used to manage the lifecycle of the individual applications as well as the usual navigation rollback functions, such as controlling the exit, opening, fallback, etc. of the applications. The window manager is used for managing all window programs, such as obtaining the size of the display screen, judging whether a status bar exists or not, locking the screen, intercepting the screen, controlling the change of the display window (for example, reducing the display window to display, dithering display, distorting display, etc.), etc.
In some embodiments, the system runtime layer provides support for the upper layer, the framework layer, and when the framework layer is in use, the android operating system runs the C/C++ libraries contained in the system runtime layer to implement the functions to be implemented by the framework layer.

As shown in fig. 4, the kernel layer contains at least one of the following drivers: audio drive, display drive, bluetooth drive, camera drive, WIFI drive, USB drive, HDMI drive, sensor drive (e.g., fingerprint sensor, temperature sensor, pressure sensor, etc.), and power supply drive, etc.
Fig. 5 is a schematic diagram of an application program that can be provided by the display device provided in some embodiments of the present application, where, as shown in fig. 5, an application program layer includes at least one application program that can display a corresponding icon control in a display, for example: a live television application icon control, a video on demand 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 provide television signals using inputs from cable television, radio broadcast, 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, the video on demand application may provide video from different storage sources. Unlike live television applications, video-on-demand provides video resources from some storage sources. For example, video-on-demand may come from a server side of cloud storage or from a local hard disk storage containing stored video programs, etc.
In some embodiments, the media center application may provide various multimedia content playing applications. For example, the media center may be other than live television or video on demand, and the user may access various images or audio through the media center application.
In some embodiments, an application center may be provided to store various applications. The application may be a game, an application, or some application that is associated with a computer system or other device but that may be run in a smart television. The application center may obtain these applications from different sources, store them in local storage, and then run on display device 200.
Based on the display device 200, the display device 200 may run the application program, acquire the target media asset from the corresponding media asset library through the server 400, and play the target media asset online. That is, in some embodiments, during the process of playing the media items, the server 400 may obtain media data from the corresponding media library in real time, and continuously form the media picture through decoding, rendering, and other processes.
The display device 200 may also enable the display device 200 to play and display the screen content in the other intelligent devices 300 by establishing a screen connection with the other intelligent devices 300. In some embodiments, the user may send a screen-drop connection request through the smart device 300, and send the screen-drop connection request to the display device 200 through a WiFi network, a WiFi direct, a wired network, the internet, or the like. The display device 200 completes the configuration of the transmission protocol according to the screen connection request, so that a transmission channel of the screen data is established between the display device and the intelligent device 300. For example, for a system application or directly at the system level, the smart device 300 may establish a transmission channel of the screen-casting data with the display device 200 using the Miracast screen-casting, the Airplay screen-casting, or the WiDi screen-casting protocol. The display device 200 receives the screen data of the smart device 300 through the transmission channel, that is, a user interface for playing the application in the smart device 300 may be displayed in the display 260.
In some embodiments, the display device 200 may also implement a screen-drop connection with the smart device 300 through different connection means. For example, when the display device 200 and the smart device 300 access the same wireless local area network, a screen-cast connection may be established based on a WiFi network. For another example, when NFC (NearFieldCo mmunication ) components are provided on both the display device 200 and the smart device 300, a screen-casting connection relationship may be established through the NFC component. For another example, the display device 200 and the smart device 300 may also establish a screen-in connection relationship through the internet. It is apparent that other wired or wireless connection methods may be used between the display device 200 and the smart device 300, so as to establish a screen-throwing connection relationship, such as ethernet, wi-fi direct, RF radio connection, infrared connection, cellular network, etc.
The display device 200 may play and display media content of different sources through the display window based on the above manner. In some embodiments, the display device 200 may display content playing a media asset through a display window; alternatively, the display device 200 may also play the content of multiple media assets in the user interface simultaneously through multiple display windows, for example, a scene where multiple display windows exist, such as multi-channel projection, floating projection, or multi-window play. That is, the display device may display and play the corresponding media content in the user interface through one or more display windows.
To facilitate interaction with the display device 200, in some embodiments, the display device 200 may enable the display device 200 to present a display window through a browser through the design principles of an embedded platform. For example, the display device 200 creates one or more display windows to play media and implements interactive functions through the display windows when running a portion of the application, since the application does not have an on-board UI system or design requirements.
In some embodiments, when interacting with a display window generated by a browser, since the display of the display interface is browser dependent, the user's interaction may also follow various interaction events of the browser. For example, the user may input a cursor operation event for controlling movement, selection, or the like of the focus cursor through the control device 100 or the smart device 300.
In addition, in order to ensure the viewing experience of the user, in some embodiments, the display device 200 further obtains the resource type of the media asset in the display window when playing the media asset through the display window. And then according to the resource type of the play media resource in the display window, the user interface is adjusted to be a corresponding image quality parameter. For example, when the media played in the display window is HDMI (HighDefinitionMulti mediaInterface, high-definition multimedia interface) video, the image quality parameters of the user interface, that is, the contrast, brightness, color temperature, etc. are adjusted according to the image quality parameters corresponding to the HDMI, so as to present the best display effect.
When a plurality of display windows exist in the user interface, only one image quality parameter can be adjusted to display the display effect of the user interface. In some embodiments, the play content in the main window is detected, and the image quality parameters of the user interface are adjusted according to the play content in the main window. That is, the display device 200 may query the image quality parameter corresponding to the resource type of the play media asset in the main window, and adjust the image quality of the display device 200 according to the image quality parameter. Wherein, the main window is an original window before the display device 200 enters the multi-window mode; when the display apparatus 200 exits the multi-window mode, only the play content of the original window is displayed in the user interface of the display apparatus 200.
For example, taking split-screen projection as an example, the display device 200 is connected with a television box through an HDMI interface, and plays the content of the media asset provided by the television box through an original window in a user interface; the display device 200 adjusts the image quality parameters of the user interface to the media playing image quality parameters suitable for the television box. At this time, the display device 200 establishes a new screen, and plays the content of the screen through a new display window split screen to enter the multi-window mode. Since the main window of the display device 200 is the original window for playing the content corresponding to the HDMI interface, no matter what type of screen projection content is played by other windows, the display device 200 keeps the image quality parameter of the user interface to be the image quality parameter suitable for the image corresponding to the HDMI interface. After the display device 200 exits the multi-window mode, the display device 200 closes the display window for displaying the screen-casting content, only displays the original window for playing the content corresponding to the HD MI interface, and continues to keep the image quality parameters of the user interface as the image quality parameters applicable to the image corresponding to the HDMI interface.
However, the adjustment of the user interface image quality parameter according to the play content of the main window may not achieve the best display effect when all the display windows in the display device 200 are considered. For example, as shown in fig. 6, window a in fig. 6 is an original window before entering the multi-window interface, i.e. a main window, and the types of resources played in window a and window B are different. The duty ratio of the window a in the user interface is far smaller than that of the window B, and the image quality parameters of the user interface are adjusted through the image quality parameters of the window a, so that the display effect of the window B is reduced, the display effect of the display device 200 in a multi-window scene is affected, and the experience of a user is reduced.
Based on the above application scenario, in order to improve the problem of poor multi-window effect in the display device 200, some embodiments of the present application provide a multi-window image quality display method, as shown in fig. 7, including the following steps:
s100: in response to playing the dynamic signal, traversing the display area and the display priority of the display window.
The playing dynamic signal is one of a playing start signal, a playing change signal and a playing end signal and is used for representing the playing state of the media asset in the display window. When the display device 200 receives the play dynamic signal, it traverses the display area and the display priority of the display window in the current user interface to understand the status of each display window in the user interface.
As shown in fig. 8, in some embodiments, the display device 200 listens for the play status of the display window. When the display window starts playing, a playing start signal is generated. Wherein the play start signal includes a display area of the display window and a display priority. When the display area or the display priority of the display window is changed, a play change signal is generated. The display change signal comprises a display area and a display priority after the display window is changed. When media play starts in the display window, generating a play start signal comprising a display area and display priority information; and generating a play change signal comprising the changed display area and the display priority information when the size of the picture area of the play media asset is changed by sounding or the resource type of the play media asset is changed in the process of displaying the media asset on the display window.
For example: when the display device 200 plays the video through the window a, a play start signal including the display area and the display priority of the window a is generated. At this time, the display device 200 establishes a screen connection with the smart device 300, displays the content of the screen through the window B, and generates a play start signal including the display area and the display priority of the window B. In the playing process, the user adjusts the size of the playing picture of the window a through the control device 100, and the display device 200 automatically generates a playing change signal of the window a, and carries the display area and the display priority of the window a after being changed in the playing change signal.
Similarly, as shown in fig. 8, when the display window ends the playback, the display device 200 also generates a playback end signal. That is, in some embodiments, the display apparatus 200 listens to the play state of the display window, and generates a play end signal when the display window ends play. That is, when the display window ends the playback of the media asset, the display device 200 may automatically generate a playback end signal to prompt the display device 200 that the current display window has ended playback.
For example: the display device 200 plays different video content through window a and window B simultaneously. At this time, the user inputs an operation event of exiting in window B to exit window B in the display device 200. The display device 200 ends the playing of the window B, closes the window B in the user interface, and automatically generates a playing end signal of the window B.
S200: and calculating the display area difference value between the maximum display window and the rest display windows.
After the display device 200 receives the playing dynamic signal and traverses the display area and the display priority of the display windows, the display device 200 screens out the largest display window with the largest display area in the display windows according to the display area. And then, calculating the difference value of the display areas of the maximum display window and the rest display window by comparing the display areas of the maximum display window and the rest display window.
Since calculating the display area difference requires comparing the display areas of the respective display windows, as shown in fig. 9, in some embodiments, the display apparatus 200 further receives a play start signal of the display window, and stores the display area and the display priority of the display window in response to the play start signal. The display areas and the display priorities of the display windows are stored in the display apparatus 200 so that the display apparatus 200 analyzes the display areas and the display priorities of the respective display windows. For example, the display area and the display priority information may be stored in the internal memory of the display device 200, or a parameter decision module may be provided to screen the largest display window with the largest display area among the display windows in the internal memory or the parameter decision module.
Upon receiving the play start signal of the display window, the display device 200 indicates that the display window has started playing the media content. In the process of playing the display window, if the playing change signal of the display window is received again, the display window is changed. For example, the display area becomes larger, the display area becomes smaller, the resource type of the play media asset in the display window is changed, or the like. At this time, the display device 200 needs to update the stored display area and the display priority information to ensure the accuracy of the stored information in the display device 200. That is, the display device 200 updates the display area and the display priority of the display window upon receiving the play change signal of the display window.
Similarly, if the display device 200 receives the play end signal of the display window, the corresponding information stored in the display device 200 needs to be removed to update the information stored in the display device 200 in real time. That is, the display device 200 removes the display area and the display priority of the display window upon receiving the play end signal of the display window.
Further, to facilitate the display device 200 to obtain the display area of the display window, in some embodiments, the display device 200 also obtains size information of the display window. Wherein the size information includes width and height information of the display window. And calculating the window area of the display window according to the width and height information, so that the window area is used as the display area of the display window.
For example: the display device 200 plays the media asset through the window a and the window B, and the display device 200 obtains the size information of the window a and the window B. Wherein the width of the window A is x 1 High is y 1 The method comprises the steps of carrying out a first treatment on the surface of the Window B has a width x 2 High is y 2 . The display device 200 is then according to x 1 And y is 1 The product of (a) calculates the window area of window A as x 1 y 1 The method comprises the steps of carrying out a first treatment on the surface of the According to x 2 And y is 2 The product of (a) calculates the window area of window A as x 2 y 2 . From this, the display area of window A is x 1 y 1 The display area of window B is x 2 y 2 ，x 1 y 1 ＞x 2 y 2 . Window A is the largest display window, and the difference between the display areas of window A and window B is x 1 y 1 -x 2 y 2 。
S300: and if the difference value of the display areas is larger than or equal to the preset difference value, adjusting the image quality parameter of the user interface to be the image quality parameter suitable for the maximum display window.
The display device 200 calculates a display area difference between the maximum display window and the remaining display window by comparing the display areas of the maximum display window and the remaining display window. The display area difference value is then compared with a preset difference value in the display device 200 to determine the duty ratio of each display window in the user interface.
If the difference value of the display areas is larger than or equal to the preset difference value, the maximum display window occupies a larger display area in the user interface, and the influence on the display effect of the user interface is larger. When the maximum display window is far larger than the rest display windows, the image quality parameters of the user interface are adjusted to be suitable for the image quality parameters of the maximum display window, so that the overall display effect of the user interface is improved. Accordingly, by presetting a difference value in the display device 200, the difference between the display area occupied by the maximum display window and the remaining display windows in the user interface is judged.
For example: the display device 200 plays different media contents through the window a and the window B respectively, and the preset difference value in the display device 200 is alpha. At this time, the display device 200 establishes a screen connection with the smart device 300 again, and plays the screen content through a new window C. When receiving the play start signal of the window C, the display device 200 saves the display area and the display priority of the window C, and traverses the display areas and the display priorities of the window a, the window B and the window C. As shown in fig. 10, window C is the largest display window in the user interface. The display device 200 calculates the difference between the display areas of the window C and the window a, and the difference between the display areas of the window C and the window a is J, and the difference between the display areas of the window C and the window B is K. J is greater than α, K is greater than α, and the display device 200 adjusts the image quality parameters of the user interface to those suitable for the window C.
As shown in fig. 11, in order to accelerate the response speed of the image quality parameter adjustment, in some embodiments, the display apparatus 200 receives a play end signal and detects the number of windows of the display window in response to the play end signal. If the number of windows is 0, inquiring default image quality parameters applicable to the non-display window, and adjusting the image quality parameters of the user interface to the default image quality parameters. The display apparatus 200, upon receiving the play end signal, indicates that there is a display window to end play, and does not need to consider the display window to end play when the display apparatus 200 adjusts the image quality parameters of the user interface. Whereas if the display device 200 has only one display window before receiving the play end signal, there is no display window in the user interface when receiving the play end signal of the display window. At this time, the display device 200 may directly present the default image quality parameters of the non-display window without querying the image quality parameters applicable to each type of display window.
For example: the display device 200 plays the media asset through the window A, and the user exits from closing the window A through the remote controller matched with the display device 200, so that a play end signal of the window A is generated. The display device 200 detects the number of windows of the display window after receiving the play end signal of the window a. And if the number of windows is 0, adjusting the image quality parameter of the user interface to be a default image quality parameter.
And if the display device 200 receives the play end signal, only one display window exists in the user interface. The display device 200 directly adjusts the user interface to the image quality parameters suitable for the current display window without traversing the display area and the display priority of the display window. That is, if the number of windows is 1, the image quality parameter of the user interface is adjusted to the image quality parameter suitable for the currently displayed window.
For example: the display device 200 plays different media through the window A and the window B respectively, and the user exits from closing the window A through a remote controller matched with the display device 200, so that a play end signal of the window A is generated. The display device 200 detects the number of windows of the display window after receiving the play end signal of the window a. When the number of windows is 1, the image quality parameter of the user interface is adjusted to be the image quality parameter suitable for the window B.
Similarly, in some embodiments, the display device 200 receives a play start signal and detects the number of windows of the display window in response to the play start signal. If the number of windows is 1, which indicates that only one display window exists in the current user interface, the image quality parameters of the user interface are adjusted to be suitable for the image quality parameters of the current display window. That is, if only one display window exists in the user interface of the display device 200, the display device 200 does not need to query the display area and the display priority of the display window, and directly adjusts the image quality parameter to the image quality parameter suitable for the current display window so as to present the corresponding display effect.
For example: the display device 200 is in a state of no display window play. At this time, the user opens a certain application in the display device, plays the media asset through the window a, and generates a play start signal of the window a. The display device 200 detects the number of windows of the display window after receiving the play start signal of the window a. When the number of windows is 1, the image quality parameter of the user interface is adjusted to be the image quality parameter suitable for the window A.
S400: if the difference value of the display area is smaller than the preset difference value, the reference window is selected, and the image quality parameter of the user interface is adjusted to be the image quality parameter suitable for the reference window.
The display device 200 calculates the difference between the display areas of the maximum display window and the rest display windows by comparing the display areas of the maximum display window and the rest display windows, and if the difference between the display areas is smaller than the preset difference value, it indicates that a display window with a smaller difference from the display area of the maximum display window exists in the user interface. In this case, the maximum display window does not occupy the main display area of the user interface, and if the image quality parameter of the user interface is adjusted to be suitable for the image quality parameter of the maximum display window, the display effect of the display window with a smaller difference cannot be considered.
Therefore, the difference value of the display area of the screening and maximum display window is smaller than the preset difference value, and the window with the highest display priority is the reference window. The reference window is a window with highest display priority among display windows with display area difference values smaller than preset difference values. By adjusting the image quality parameters of the user interface to the image quality parameters suitable for the parameter adjustment reference window, a plurality of display windows in the user interface can be considered, so that the user interface achieves the optimal display effect.
In order to secure an image quality display effect of the display apparatus 200, the display apparatus 200 may set a priority rule of the display apparatus 200 based on a type of a resource played in the display apparatus 200. Thus, in some embodiments, the display device 200 also detects the type of resource played in the display window, and then maps the display priority of the display window according to the type of resource.
For example: the resource types played in the display device 200 include HDMI, network video, DLNA (DigitalLiving NetworkAlliance ) push video and Miracast mirror video, and the display priority of the display window is HDMI, network video, DLNA push video and Miracast mirror video. The display device 200 may map the display priority corresponding to the display window by detecting the resource type of the media asset played in the display window.
For example, when the display device 200 sets the display priority based on the resource type, the display area and the display priority of the display window may be stored in the format of the display area and the resource type. For example, window1: {100, HDMI }; window2: {800, DLNA }. Window1 and Window2 represent two different display windows, 100 and 200 represent display areas corresponding to the windows, and HDMI and DLNA represent resource types corresponding to the display windows, namely according to the "windows: the format of { display area, resource type } "stores display area and display priority information of a display window.
Since the display device 200 selects the display window with the highest priority according to the display priority of the display window when screening the reference window. Thus, in some embodiments, the display device 200 obtains priority rules preset in the display device. Wherein the priority rule is set according to the resource type. And screening the parameter adjustment reference window according to the priority rule, detecting the type of the resources played in the parameter adjustment reference window, and inquiring the image quality parameters according to the type of the resources.
That is, the display apparatus 200 sets the display priority of the display window according to the resource type. When the reference window is screened, the display window with the highest display priority is screened out according to the priority rule of the threshold value. And acquiring the resource type through the display priority, inquiring the image quality parameter applicable to the type according to the resource type, and adjusting the image quality parameter of the user interface to the image quality parameter of the type so as to achieve the optimal display effect.
For example: the priority rule of the display device 200 is HDMI>Network video>DLNA push video>Miracast mirror image video, presetThe difference value is alpha. When the display device 200 plays the HDMI video through the window a, a DLNA screen is established with the smart device 300 to display the contents of the DLNA screen through the window B. The display device 200 automatically generates a play start signal of the window B, and the display device 200 traverses the display areas and the display priorities of the window a and the window B in response to the play start signal of the window B. The display area of window A is x 1 y 1 The display area of window B is x 2 y 2 . Wherein x is 1 y 1 ＞x 2 y 2 Window a is the largest display window. The display device 200 calculates the difference between the display area of the maximum display window and the display area of window B to obtain x 1 y 1 -x 2 y 2 < alpha, according to the priority rule HDMI>Network video>DLNA push video>The Miracast mirror image video screens out a parameter-adjusting reference window with the highest priority, and the parameter-adjusting reference window is window A. The display device 200 queries the image quality parameter corresponding to the HDMI video, and adjusts the image quality parameter of the user interface to the image quality parameter corresponding to the HDMI video.
It should be noted that the priority rule in the above example is only illustrative, and the priority rule may include more resource types, and the priority rule may be set according to other aspects. Alternatively, the priority rule may be a superposition of one or two rules, and the display priority with the highest weight is selected according to the superposed weight value. The present application is not limited in this regard.
