As shown in Figure 4, the kernel layer at least includes at least one of the following drivers: audio driver, display driver, Bluetooth driver, camera driver, WIFI driver, USB driver, HDMI driver, sensor driver (such as fingerprint sensor, temperature sensor, touch sensors, pressure sensors, etc.), etc.

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

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

In some embodiments, taking the magic mirror application (photography application) as an example, when the remote control receiving device receives the input operation of the remote control, the corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the input operation into the original input event (including the value of the input operation, the timestamp of the input operation and other information). Raw input events are stored at the kernel layer. The application framework layer obtains the original input event from the kernel layer, identifies the control corresponding to the input event according to the current position of the focus, and regards the input operation as a confirmation operation, and the control corresponding to the confirmation operation is the control of the magic mirror application icon. The mirror application calls the interface of the application framework layer, starts the mirror application, and then starts the camera driver by calling the kernel layer to capture still images or videos through the camera.

Enter an event and report the event to the application framework layer. The window mode (such as multi-window mode) and window position and size corresponding to the input operation are set by the activity manager of the application framework layer. The window management of the application framework layer draws the window according to the settings of the activity manager, and 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 screen.

In some embodiments, the application layer includes at least one application that can display a corresponding icon control on the display, such as: live TV application icon control, video on demand application icon control, media center application icon control, application center Icon controls, game application icon controls, etc.

Referring to Figure 9, the method includes the following steps:

Step S91: Determine whether the server is configured with a blacklist and a whitelist.

If the server is not configured with a black and white list, go to step S92; if the server is configured with a black and white list, go to step S93.

Step S92: The server configures the blacklist and whitelist lists.

The whitelist includes signal sources and third-party applications that allow screenshots.

In some embodiments, the HDMI (High Definition Multimedia Interface, High Definition Multimedia Interface) channel, AV (Audio Video, audio and video playback device system) channel (this channel can be connected to playback devices such as DVD, power amplifier), DMP ( Digital Media Player, local media player), TV (live TV), and third-party applications that allow screenshot operations are added to the whitelist, that is, the server sets the source list type to whitelist (SourceListType:white).

In some embodiments, for copyright-protected content such as Netflix and Youtube, the screenshot operation is not allowed, and it is added to a blacklist, that is, the cloud sets the source list type to a blacklist (SourceListType: black).

In some embodiments, according to the requirements of different national and regional signal sources and third-party applications, only the whitelist may be configured, or only the blacklist may be configured, or the blacklist and the whitelist may be configured together.

Step S93: Determine whether the server control switch is turned on.

The server control switch (Kill Switch) is used to control the switch of the signal source in the whitelist and the intelligent image mode switching function of the third-party application. The server enables and disables the intelligent image mode switching function of the display device by controlling the Kill Switch switch, thereby controlling the display and hiding of the intelligent scene switch of the display device.

In some embodiments, the Kill Switch can be set to 1 for on and 0 for off. Kill Switch is the master switch for the server to control the switching of intelligent image modes. Black and white lists are switches for individual sources or third-party applications.

If the server control switch is not turned on, step S94 is performed.

Step S94: Turn off the intelligent image mode switching function of the signal source or the third-party application, and control the display to hide the intelligent scene switch in the image setting user interface in response to the user's input to turn on the signal source or the image setting instruction of the third-party application.

Wherein, an instruction to turn on the signal source or the image setting of the third-party application program input by the user operating the control device is received through the user interface. For example, the user interface may receive an instruction from the user to turn on the signal source or the image setting of the third-party application program by pressing the confirmation key on the control device.

If the server control switch is on, step S95 is executed.

Step S95: Determine whether the signal source or the third-party application is in the blacklist or whitelist.

If the signal source or the third-party application is in the blacklist, step S94 is performed.

If the signal source or the third-party application is in the whitelist, step S96 is performed.

Step S96: Turn on the intelligent image mode switching function, and control the display to display the intelligent scene switch in the image setting user interface in response to the user's input of a signal source opening or an image setting instruction of a third-party application.

After the intelligent image mode switching function is enabled, the display device will identify the scene of the currently playing content through screenshots, and automatically apply scene-specific image quality parameters according to the identified scene. Applicable scenarios: physical channel (HDMI, DTV, AV, etc.), DMP media center, DLNA (Digital Living Network Alliance, Digital Living Network Alliance) screen projection, etc. Recognition scenes: such as sky (SKY), grass (Green), face (Face), architecture (Architecture), these scenes will be different according to different solution providers and models, and the recognized scene is ultimately determined by the machine learning model. In some embodiments, the image quality parameters utilized in different scenarios are shown in Table 1:

Table 1

In some embodiments, the user can turn on or off the smart scene switch in the image setting according to his own needs.

Step S97: In response to the user's input of an instruction to close the smart scene, the smart image mode switching function is turned off.

The instruction to close the smart scene input by the user operating the control device is received through the user interface. For example, the user interface may receive the user's input of an instruction to close the smart scene by pressing a confirmation key on the control device.

Step S98: In response to an instruction to enable the smart scene input by the user, the smart image mode switching function is enabled.

The instruction for starting the smart scene input by the user operating the control device is received through the user interface. For example, the user interface may receive the user's input of an instruction to start the smart scene by pressing the confirmation key on the control device.

By switching the smart scene switch, the user can turn on or off the smart image mode switching function independently, thereby realizing the customization of the smart image mode switching function of the display device.

In the above embodiment, a whitelist is configured according to the requirements of third-party applications or signal sources in different countries and regions, and the intelligent image mode switching function of the display device is enabled and disabled by controlling the server control switch, thereby controlling the intelligent scene switch of the display device. The display and hide function of the smart picture mode can avoid conflicts with third-party applications or signal source restrictions in some countries.
