And after the kernel is started, loading the Shell and the user application program. The application program is compiled into machine code after being started, and a process is formed.

Referring to fig. 4, in some embodiments, the system is divided into four layers, which are an Application (Applications) layer (abbreviated as "Application layer"), an Application Framework (Application Framework) layer (abbreviated as "Framework layer"), an Android runtime (Android runtime) and system library layer (abbreviated as "system runtime library layer"), and a kernel layer from top to bottom.

In some embodiments, at least one application program runs in the application program layer, and the application programs may be windows (windows) programs carried by an operating system, system setting programs, clock programs or the like; or 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 a programming framework for the application. The application framework layer includes a number of predefined functions. The application framework layer acts as a processing center that decides to let the applications in the application layer act. The application program can access the resources in the system and obtain the services of the system in execution through the API interface.

As shown in fig. 4, in the embodiment of the present application, the application framework layer includes a manager (Managers), a Provider or a Content Provider (Content Provider), and the like, where the manager includes at least one of the following modules: an Activity Manager (Activity Manager) is used for interacting with all activities running in the system; the Location Manager (Location Manager) is used for providing the system service or application with the access of the system Location service; a Package Manager (Package Manager) for retrieving various information related to an application Package currently installed on the device; a Notification Manager (Notification Manager) for controlling display and clearing of Notification messages; a Window Manager (Window Manager) is used to manage icons, windows, toolbars, wallpapers, and desktop components on a user interface.

In some embodiments, the activity manager is used to manage the lifecycle of the various applications as well as general navigational fallback functions, such as controlling exit, opening, fallback, etc. of the applications.

In some embodiments, the system runtime layer provides support for the upper layer, i.e., the framework layer, and when the framework layer is used, 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 driver, bluetooth drive, camera drive, WIFI drive, USB drive, HDMI drive, sensor drive (like fingerprint sensor, temperature sensor, pressure sensor etc.) and power drive etc..

In general, the video played in the display device 200 generally has three dimensions, namely, the channel where the video is located, the signal format of the video, and the current image mode.

The channels include physical channels such as HDMI (High Definition Multimedia Interface), TV, AV, and VGA (Video Graphics Array), and also include virtual channels such as Youtube (Video website), Netflix (web fly), Amazon (Amazon), VUDU (online movie renter), and DMP (Digital Media Player). The external storage devices such as the usb disk in the embodiment of the present application are DMP channels.

Signal formats currently include six of SDR (Software Definition Radio), HDR (High-Dynamic Range image), HDR10, HDR10+, HLG (Hybrid Log Gamma, a standard for HDR), and Dolby Vision.

Further, the signal formats include different image patterns, for example, SDR, HDR10, HDR10+, HLG, which are roughly Standard, Natural, Cinema, Dynamic, Sports, Game, Calibrated, and the like.

On some display devices 200 that support playing Dolby Vision signals, there are also image modes such as Dolby Vision Bright, Dolby Vision Dark, Dolby Vision Custom, Dolby Vision Game, etc. The different image modes correspond to different image effects respectively.

When the display device 200 supports Dolby Vision and the number of local dimming partitions is less than 64, in the Dolby Vision Dark mode, the display device 200 may turn on a global dimming function, and at this time, the display device 200 needs to automatically adjust a backlight according to metadata global dimming data carried by video resources and the like, so as to restore the most real brightness when the video resources are shot, thereby improving the image quality effect. In Dolby Vision Dark mode, the screen brightness of the display device 200 is no longer controlled by the backlight of the UI (User Interface), and the User cannot adjust the backlight option of the UI on the display device 200.

At present, the display device 200 may play the video content in a full screen manner or in a window manner. Full-screen playing is common, such as playing a tv show, a movie, etc. The window playing is generally a playing mode in which the display device 200 provides preview content for a user, for example, after the display device 200 is connected to a usb disk, the display device 200 may display small windows corresponding to various video resources in the usb disk, as shown in fig. 5. The first few seconds of the corresponding video will be played in a small window named "artistic essence" shown in fig. 5 for the user to preview.

In general, the display apparatus 200 defaults to the Dolby Vision Bright mode when playing the Dolby Vision video, and thereafter the user can switch the image mode to the Dolby Vision Dark mode according to his own needs. However, when the number of local dimming partitions of the display device 200 is less than 64, the display device 200 may turn on a global dimming function in the Dolby Vision Dark mode, and the video content played in the small window of the usb disk may change in brightness.

It can be seen that, when the display device 200 plays the Dolby Vision video on the usb disk through the small window, if the current image mode is the Dolby Vision Dark mode, the problem of unstable video image brightness occurs, and the user experience is further affected.

In order to solve the above problem that when the Dolby Vision video content of an external storage device such as a usb disk is previewed on the display device 200 through a small window, the picture is changed continuously in brightness, the embodiment of the present application provides a display device 200. The display device 200 may set a current image mode as a target mode after the external storage device 500 such as a usb disk is accessed and when a peripheral interface of the external storage device 500 is displayed, so that, even if the image mode has been set to a Dolby Vision Dark mode or other modes between users, the display device 200 may play back in the target mode such as Dolby Vision Bright while playing back a Dolby Vision video in a small window on the external storage device 200, thereby avoiding a problem of unstable picture brightness caused by using the Dolby Vision Dark mode.

FIG. 6 illustrates a schematic diagram of a display device 200 with an external storage device 500 connected thereto, according to some embodiments. As shown in fig. 6, after the display device 200 is connected to the external storage device 500, the peripheral interface of the external storage device 200 is usually displayed directly. On the peripheral interface, the files in the external storage device 500 may be displayed. If the file is a video resource, the video resource can be directly displayed in a window form on the peripheral interface, and the image content of a certain frame of the video resource, the total duration of the video resource and the like can be displayed on the window.

FIG. 7 illustrates a schematic diagram of a peripheral interface on display device 200, according to some embodiments. Taking the external storage device 500 as an example, which only stores 5 video resources, as shown in fig. 7, 5 video windows corresponding to the 5 video resources are displayed on the peripheral interface. After the user watches the peripheral interface, the user can select target content to continue to view by moving the focus on the interface. When the focus moves onto the video window, the video window may automatically cycle through a period of video content after waiting a period of time. For example, after the focus is moved to 2s of the second video window in fig. 7, the video content of the first 5s is automatically played in a loop in the second video window.

FIG. 8 illustrates a schematic diagram of an image mode settings page on display device 200 according to some embodiments. As shown in fig. 8, the image modes displayed on the image mode setting page may include image modes such as Dolby Vision Bright, Dolby Vision Dark, Dolby Vision Custom, Dolby Vision Game, and the like. When a user watches any Dolby Vision video on the display device 200, the user can select a target image mode for use according to the requirement of the user. For example, the user may select the Dolby Vision Dark option on the image mode setting page by moving the focus to the Dolby Vision Dark option through the control device 100 such as a remote controller, and then pressing "ok" or the like on the control device 100, and thereafter, the display apparatus 200 may play the Dolby Vision video content using the Dolby Vision Dark mode.

When the display apparatus 200 displays the above-described peripheral interface, the display apparatus 200 automatically sets the image mode to the Dolby Vision Bright mode even though the user has previously set the Dolby Vision Dark or other image mode. At this time, the display apparatus 200 also automatically updates the selected image mode on the above-described image mode setting page, i.e., changes the Dolby Vision Bright mode to the selected mode on the image mode setting page.

When the display device 200 is in the Dolby Vision Bright mode, no matter whether the local dimming partition of the display device 200 is smaller than 64, the global dimming function is not started when the video preview content is played on the video window on the external interface, and further, the picture played on the video window does not have the condition of brightness change.

In the display device 200, processing levels such as an application layer, a middleware layer, and a driver layer are generally set to implement different processes in playing a video. FIG. 9 illustrates a schematic diagram of the process flow between various processing levels in the display device 200, according to some embodiments. As shown in fig. 9, the application layer may perform display processing of a user interface and a peripheral interface, on which a user may select to play different video contents, or modify various settings or parameters of the display device 200, or the like. The middleware layer plays a role in starting and stopping, can be used for transmitting parameters modified by a user and the like to the driving layer, and can update the configuration corresponding to the playing signal and send the configuration to the driving layer when the video is played. The driving layer can receive the parameters transmitted by the middleware layer and enable the parameters to be effective, and also can decode the video when the video is played, and can throw the analyzed video information to the middleware layer.

The display device 200 in the embodiment of the present application may implement a process of automatically setting an image mode when displaying a peripheral interface, a process of playing a preview video content in a video window in the set image mode, and the like based on the application layer, the middleware layer, and the driver layer. And, the middleware layer may automatically set a target mode when the display device 200 displays the peripheral interface and transmit the target mode to the driver layer, so that the driver layer plays the video content in the target mode.

In order to solve the above-mentioned problem that when the Dolby Vision video content of an external storage device such as a usb disk is previewed on the display device 200 through a small window, the present embodiment further provides a video playing method, which may be applied to the display device 200 of the foregoing embodiment, and the controller 250 in the display device 200 may be configured to implement the steps in the video playing method. FIG. 10 illustrates a schematic diagram of a video playback method according to some embodiments. As shown in fig. 10, the method may include the steps of:

step S101, when the display device 200 displays a peripheral interface including a plurality of video windows, setting an image mode of the display device 200 to a target mode.

Wherein the target mode may be the Dolby Vision Bright mode described in the foregoing embodiments. And the peripheral interface is a user interface provided by the display device 200 for the external storage device, and each video window on the peripheral interface corresponds to one video content.

The display device 200 may be a peripheral interface that is directly displayed after the access of the external storage device 500. Or, the display device 200 may also display the peripheral interface after exiting from another display page, for example, the user has selected a certain target video content on the peripheral interface to perform full-screen playing, when the user controls the display device 200 to exit from the current full-screen playing page, the display device 200 may display the peripheral interface including a plurality of video windows, where the peripheral interface includes not only the video window corresponding to the video content that has exited from full-screen playing, but also other unselected video windows.

When the external storage device 200 is not connected, the display device 200 may also play video resources in other channels. In addition, the user can select different image modes according to the requirement of the user. When the video asset being played is a Dolby Vision asset, the display device 200 may also provide the user with four image modes as shown in fig. 8. When the user selects a certain image mode, the external storage device 500 is accessed to the display device 200, and then the image mode can still be set to the target mode when the display device 200 displays the peripheral interface.

Step S102, controlling the display device 200 to play the preset duration content of the target video in the target video window in the target mode, so that the user can preview the target video in the target video window.

The preset duration content is usually the content of the first few seconds of the target video, for example, 5s, 3s, and the like. And if the preset time content in the target video window is played completely, the user does not perform other operations all the time, that is, the focus is positioned on the target video window all the time, then the preset time content is played in the target video window in a circulating manner until the user performs other operations.

In some embodiments, if the display device 200 directly displays the peripheral interface after accessing the external storage device 500, the display device 200 may set the image mode to the target mode when the user selects the target video window. Further, in step S101, as shown in fig. 11, step S201 to step S207 may be further included. In step S201, the display device 200 is controlled to display a peripheral interface including a plurality of video windows. Step S202, whether a third user operation of moving the focus on the peripheral interface by the user is received or not is determined. The third user operation may be an operation in which the user moves the focus on the external interface by controlling the control device 100 such as a remote controller, or may be an operation in which the user positions the focus on the external interface by inputting a voice command to the display device 200. In step S203, if the third user operation is received, the display device 200 controls the focus to be positioned at the target position in response to the third user operation. If the above-described third user operation is not received, the display apparatus 200 is not controlled to perform any operation in step S204, and the current state and setting of the display apparatus 200 are maintained.

In some cases, when the display device 200 displays the peripheral interface, in addition to displaying several video windows, other menu windows or active windows may be displayed on the peripheral interface, for example, a search window located above the video windows in fig. 7, and some selection windows with pull-down options, etc. If the focus is positioned on these non-video windows, the display device 200 needs to display the corresponding content or options on the respective non-video windows.

In order to determine whether the user selects the target video window on the peripheral interface during the operation, as shown in fig. 11, in step S205, it is further required to determine whether the target position after the focus is located is the position of the target video window. Also, in step S206, if the target position is the position where the target video window is located, the image mode of the display apparatus 200 is set to the target mode. If the target position is not the position of the target video window, the display device 200 is not controlled to perform any operation and the current state and setting of the display device 200 are maintained in step S207.

In some embodiments, when determining whether the target position is the position of the target video window, the determination may be made by obtaining the area size of the target position. Generally, the size of the video window under the DMP channel is fixed, and then it can be determined whether the area size of the target position is the fixed size of the video window. This fixed size may be a preset size, for example, the size of the video window is 687mm in width, 921mm in height, etc. If the area size of the target position is a preset size, it may be determined that the target position is the position where the target video window is located, i.e., the focus is positioned on the target video window. If the area size of the target position is not the preset size, it may be determined that the target position is not where the target video window is located, i.e., the focus is not positioned on the target video window.

In some embodiments, when the display device 200 directly displays the peripheral interface, as shown in fig. 12, in the process of implementing the set target mode based on the application layer, the middleware layer and the driver layer in the foregoing embodiments, the middleware layer may determine whether the focus on the display device 200 is positioned on the video window of the peripheral interface in the manner described above, that is, determine whether the display device 200 needs to play video content in the video window of the peripheral interface. If the display device 200 needs to play the video content in the video window, the middleware layer also directly sets the image mode to be the target mode and issues the target mode to the driver layer to be effective, so that the driver layer plays the video in the video window in the target mode, thereby avoiding the opening of the global scaling function when the Dolby Vision Dark mode is used, and avoiding the phenomenon that the picture of the video content played in the video window of the DMP channel such as the U disk is continuously changed in brightness.

In the foregoing aspect, before the display apparatus 200 automatically sets the target mode, the image mode historically set in the display apparatus 200 by the user may be the Dolby Vision Dark mode, the Dolby Vision Bright mode, or another mode. If the user's history is set to a mode other than the Dolby Vision Dark mode, the brightness of the picture in the target video window may be always maintained stable during the display of the peripheral interface and the automatic setting of the target mode by the display apparatus 200.

However, if the history of the user is set to the Dolby Vision Dark mode, the picture in the target video window is first darkened at the start of video display and then continuously and stably brightly displayed all the time in the process that the display apparatus 200 displays the peripheral interface and automatically sets the target mode. In the embodiment of the present application, this phenomenon can be specifically described as follows based on the application layer, the middleware layer, and the driver layer in the foregoing embodiments.

In the process shown in fig. 12, when a user enters a DMP channel (e.g., a usb disk) to select a full-screen playing video, the DMP notifies the driver layer first, decodes the video by the driver layer, decodes the currently playing video to obtain a Dolby Vision signal, and notifies the middleware layer of the Dolby Vision signal. After receiving the message of the driver layer, the middleware layer refreshes the image mode and the parameters corresponding to the Dolby Vision (namely, the image mode and the parameters set when the Dolby Vision video is played last time are acquired) and then takes effect to the driver layer. It can be seen that when the Dolby Vision video is played, the driver layer knows first and the middleware layer knows later.

If the Dolby Vision image mode set by the user in the last playing is the Dolby Vision Dark mode, the middleware layer sends the Dolby Vision Dark mode to the driver layer to be effective, and the driver layer memorizes the Dolby Vision Dark mode. When the display device 200 plays the Dolby Vision video in the video window of the DMP, the driver layer knows first and plays the video in the memorized Dolby Vision Dark mode, so that the picture is firstly Dark and then is informed to the middleware layer, and the middleware layer automatically sets the Dolby Vision Bright mode and sends the Dolby Vision Bright mode to the driver layer to take effect, so that the picture is Bright and keeps the brightness unchanged.

As can be seen, in the manner that the display device 200 determines that the user moves the focus to the target video window and then sets the target mode, although it can be guaranteed that the brightness of the picture in the video window is kept stable as a whole, if the Dolby Vision Dark mode is set previously, the video in the video window is still Dark when being broadcast, and the user may still feel abnormal.

In order to further avoid the phenomenon that the video in the video window is not dark when being played, in the step S101, when the display device 200 displays the peripheral interface, the image mode of the display device 200 can be directly set to the target mode, that is, it is not necessary to care whether the user moves the focus or not and it is not necessary to care whether the user selects the target video window. After the target mode is set when the display device 200 displays the peripheral interface, if the user selects the target video window on the peripheral interface, the display device 200 can directly play the video in the target video window by using the set target mode when the video is played, so that the target mode is prevented from being set after the video is played, the video in the video window has stable brightness from the beginning of the playing, and the phenomenon of brightness change is avoided.

In addition, as described in the foregoing, the display device 200 may display the peripheral interface, or the display device 200 may first play the Dolby Vision video in the external storage device 500 in a full screen mode and then quit the full screen mode. The user may set the current image mode according to the own requirement when playing the Dolby Vision video in full screen, and then, when the user selects to quit full screen playing, the display device 200 may display the peripheral interface, and at this time, according to the content of the foregoing embodiment, the previously set image mode may be changed to the target mode.

Further, in some embodiments, as shown in fig. 13, in step S101, step S301 to step S305 may be further included. In step S301, it is determined whether the display device 200 is currently playing the video content in the external storage device 500 in a full screen. In step S302, if the display device 200 currently plays the video content in the external storage device 500 in full screen, it may be continuously determined whether a first user operation of a user selecting to exit the full screen playing interface is received. If the display apparatus 200 does not display the video content in the external storage apparatus 500 in full screen, the target mode is not set and the current state and setting of the display apparatus 200 are maintained in step S303.

In step S304, if the first user operation is received, the display apparatus 200 is controlled to display a peripheral interface including several video windows in response to the first user operation, and an image mode of the display apparatus 200 is set to a target mode. Whereas if the first user operation is not received, the target mode is not set and the current state and setting of the display apparatus 200 are maintained in step S305.

The first user operation may be an operation in which the user presses a "back" key of the control apparatus 100 such as a remote controller to control the display device 200, or an operation in which the user inputs a voice command to the display device 200 to realize a control function.

In the process shown in fig. 13, after the target mode is set, it may be continuously determined whether the display device 200 receives a second user operation of selecting the target video window on the peripheral interface by the user, and if the display device 200 receives the second user operation, the focus on the peripheral interface may be located at the position of the target video window in response to the second user operation. Moreover, when responding to the second user operation, it is also necessary to determine whether the target position where the user selects the moving focus is the position where the target video window is located.

In addition, regardless of which way of setting the target mode in the foregoing embodiment, when determining whether the user moves the focus onto the target video window, if it is determined that the target position where the user moves the focus is not the position where the target video window is located, it is necessary to determine the previously set history mode and control the display apparatus 200 to continue playing the video content currently selected by the user in the history mode.

For example, when the display device 200 displays the Dolby Vision video, the user sets the Dolby Vision Dark mode according to his or her own needs, and if the user moves the focus on the peripheral interface thereafter but does not select any video window, the current Dolby Vision Dark mode is not changed to the target mode in the above step S101. The display device 200 will still play other Dolby Vision video using Dolby Vision Dark mode.

It should be noted that, the method for implementing the foregoing embodiment of the present application is premised on that the video content played by the display device 200 belongs to a Dolby Vision resource, or the format of the video content is Dolby Vision. Furthermore, in the foregoing embodiment, if the target position where the user moves the focus location on the peripheral interface is the position where the target video window is located, it needs to continuously determine whether the content of the target video corresponding to the target video window is a Dolby Vision (Dolby Vision) resource; in the case where the content of the target video is the dolby view resource, the image mode of the display apparatus 200 is set to the target mode again.

Alternatively, when the display apparatus 200 receives a first user operation and displays a peripheral interface in response to the first user operation, it is determined whether video content played full screen is a Dolby Vision (Dolby Vision) resource; in the case where the video content is the dolby view resource, the image mode of the display apparatus 200 is set to the target mode again.

In addition, in some embodiments, before step S101, it is further required to determine whether the display device 200 is connected to the external storage device 500. If the display device 200 is connected to the external storage device 500, the display device 200 may be continuously controlled to display a peripheral interface corresponding to the external storage device 500. If the display device 200 is not connected to the external storage device 500, the display device 200 does not need to display a peripheral interface.

As can be seen from the above, the present embodiment provides a video playing method and a display device, wherein the video playing method may be applied in the display device 200, and the controller 250 in the display device 200 may be configured to execute the steps in the video playing method. According to the scheme of the embodiment of the application, when the display device 200 displays the peripheral interface of the external storage device 500, no matter what mode is set before the image mode, the image mode is automatically set to be the Dolby Vision Bright mode, the brightness of the video content picture displayed afterwards is controlled to be stable, and then when a user selects a video window corresponding to a certain target video on the peripheral interface, the display device can play a section of content of the target video in the video window in the Dolby Vision Bright mode, and the problem of brightness change of the picture cannot occur during playing of the section of content, so that the user has good preview experience.
