Referring to FIG. 8, applications that trigger exit from speaker mode (open screen) include, but are not limited to, infrared voice, return key, home key, Power key; voice; pushing the bright screen; one-touch instant sowing; video calls, etc. After receiving the open screen broadcast, the sound box mode application judges whether the current scene is a scene with no service interruption; if the service is not interrupted, setting the current mode as a common television mode; if the scene is interrupted by the service, transition broadcast needs to be sent, the network television mode is pulled up, and the network television homepage is displayed. And sending a broadcast notification to each application, exiting the sound box mode at present, calling a screen opening interface, and controlling the display to open the screen.

Therefore, when the display equipment enters the sound box mode, the display is in a screen off state; and if the common television function of the display equipment is to be used again, the display equipment is required to exit the sound box mode, and the display is controlled to be in the screen-opening state. Therefore, the fast on-off of the screen can be realized, and the on-off state of the display in the loudspeaker box mode needs to be fast switched for improving user experience. The difference between the display device entering the speaker mode and exiting the speaker mode is that the states of the switch panel of the display are different, and the rest states are the same, for example, the host is always in a running state, and can normally respond to a control instruction, and the like.

FIG. 9 illustrates a first flowchart of a method for automatically turning on and off a screen in a speaker mode, in accordance with some embodiments; fig. 10 illustrates a first data flow diagram of a method of automatically switching a screen in speaker mode, according to some embodiments. An embodiment of the present invention provides a display device, including: a display configured to present a user interface; a controller connected to the display, the controller being configured to perform the following steps when executing the method of automatically turning on and off the screen in the speaker mode shown in fig. 9 and 10:

and S11, responding to a display calling instruction sent by a designated application, and judging whether the local terminal of the display device is in a sound box mode, wherein the designated application is an application which needs to present content in the display during operation, and the sound box mode is a mode in which a controller of the display device is in an operation state and the display is in a screen-off state.

When an application configured in a display device runs, the display needs to be called, that is, the content of the application is displayed in the display. For this reason, it is required that the display should be in an open state while running the application.

And if the display equipment enters the loudspeaker box mode, the display is in a screen off state at the moment. Therefore, in order to accurately determine whether the applied content can be displayed in the display in time, whether the local terminal of the display device is in a sound box mode or not can be judged first, namely, whether the current use state of the display is an on-screen state or an off-screen state is judged.

And calling the designated application of the display to be the application which needs to present the content in the display during the operation, so that when the designated application is triggered, a display calling instruction is generated to call the display to realize the display of the corresponding content.

The display invocation command may be generated by triggering a local end-machine application, such as DMP, Hi music, video call, etc. In an implementation scenario, if the local terminal receives a video call request from the opposite terminal, the local terminal video call application may generate a display call instruction.

In some embodiments, the controller, in receiving the display invocation instruction sent by the specified application, is further configured to:

step 1111, when the designated application is a video call application, receiving a video call request sent by the opposite terminal device when the opposite terminal video call application is triggered.

Step 1112, in response to the video call request, starting a local video call application of the display device, and generating a display call instruction.

When the designated application is a video call application, if an opposite-end user wants to perform video call with a home-end user, the opposite-end user operates opposite-end equipment used by the opposite-end user, starts the video call application configured in the opposite-end equipment, generates a video call request, and sends the video call request to home-end display equipment.

The local terminal display equipment can start the video call application configured by the local terminal after receiving the video call request, and judges that the application needs to call the display when the local terminal video call application is started, so that a display calling instruction is synchronously generated.

The opposite terminal equipment can be an intelligent terminal or display equipment, and the intelligent terminal can be a mobile phone, an iPad and the like. The process of the intelligent terminal triggering the video call application to generate the video call request may refer to the implementation process of the subsequent steps S31 to S33, and the process of the opposite-end display device triggering the video call application to generate the video call request may refer to the implementation process of the subsequent steps S21 to S23, which is not described herein again.

In some embodiments, if the designated application started by the local terminal is DMP, Hi music, or the like, no peer device exists in this scenario, and therefore, the display calling instruction may be synchronously generated according to the start instruction of the designated application by the local terminal.

After a display calling instruction is generated, in order to conveniently and accurately determine whether the designated application can directly call the display or not so as to display the content of the designated application in the display in time, whether the local terminal is in a sound box mode or not needs to be judged first, namely, whether the current use state of the display is an on-screen state or an off-screen state is judged.

In some embodiments, the controller is further configured to, in performing the determining whether the local terminal of the display device is in the speaker mode:

step 1121, obtaining the attribute value of the local terminal system of the display device.

And step 1122, if the system attribute value of the local terminal of the display device is 1, determining that the local terminal of the display device is in a sound box mode.

And 1123, if the system attribute value of the local terminal of the display equipment is 0, determining that the local terminal of the display equipment is not in a sound box mode.

Based on the content of the foregoing embodiment, it is determined whether the local terminal is in the speaker mode, and the determination may be performed by obtaining a local system attribute value (sys.tvbox.state), and if the local system attribute value sys.tvbox.state is 1, it is determined that the local terminal is in the speaker mode. And if the system attribute value sys.tvbox.state of the local end is 0, determining that the local end is not in the loudspeaker box mode.

When in the speaker mode, the specific application is started at this time and the screen needs to be turned on, for example, the screen needs to be turned on (the screen is opened) for the video call between the two users. At this moment, the home terminal user can listen to the video call conveniently, and the hanging up is inconvenient to select at any moment. When the terminal is not in the loudspeaker box mode, the display of the local terminal display device is in the open screen state, and the content of the designated application can be directly displayed, for example, a video call interface can be directly displayed.

And S12, when the local end of the display equipment is in the sound box mode, switching the use state of the display to be the open screen state so as to enable the local end of the display equipment to exit the sound box mode, displaying the content of the appointed application in the display in the open screen state, and after the operation of the appointed application is finished, switching the use state of the display to be the close screen state so as to enable the local end of the display equipment to enter the sound box mode.

When the appointed application is started, if the local terminal of the display equipment is in a sound box mode, the display is in a screen off state. In order to facilitate timely display of the content of the designated application, the display device needs to be controlled to exit from the sound box mode first, and the display is notified to switch the use state, that is, the use state of the display is switched from the off-screen state to the on-screen state.

After the switching of the screen-opening state is completed, the display is lightened, and the content of the specified application can be presented in the display in the screen-opening state.

In some embodiments, after the designated application is completely run, if the display device is originally in the speaker mode, the display device needs to be controlled to enter the speaker mode again while exiting the designated application.

At the moment, when the designated application exits, an application exiting instruction is generated, the home terminal responds to the application exiting instruction, and the using state of the display is switched from the screen-open state to the screen-close state, so that the home terminal enters the loudspeaker box mode again.

Therefore, after the display device enters the speaker mode, when an application needs to be opened, the speaker mode is informed to be automatically opened. And after the current service is executed, turning off the screen again.

And S13, when the local end of the display device is not in the sound box mode, displaying the content of the specified application in the display in the open screen state, and canceling the display of the content of the specified application in the display after the running of the specified application is finished.

When the appointed application is started, if the local terminal of the display equipment is not in the sound box mode, the display is in the screen-opening state. Thus, the content of the specified application may be presented directly in the display.

After the designated application is finished running, the display device is originally in the non-sound box mode, so that after the designated application exits, the designated application can directly exit without switching the sound box mode, namely, the display of the content of the designated application in the display is cancelled.

In some embodiments, if the designated application is a video call application, for example, when a video call is made with a television via a mobile phone (television), the home screen needs to be lit up for the video call, and the video call application notifies the speaker mode.

When the video call application is operated, if a video call interface needs to be displayed, a display device is required to be provided with a camera. Therefore, after the local terminal is on the screen, the condition of the camera needs to be detected so as to be capable of displaying the content of the video call application in the display.

In some embodiments, the controller, in executing presenting the content of the specified application in the display in the open state, is further configured to:

and step 141, when the designated application is a video call application and the display is in a screen-open state, detecting the running state of the camera, wherein the screen-open state is used for representing that the local terminal is not in a sound box mode.

And 142, if the running state of the camera is the calling-available state, displaying a video call interface generated by the video call application in running in the display.

And 143, if the running state of the camera is the non-invokable state, generating a camera fault prompt, and displaying the camera fault prompt in a display.

When the designated application is a video call application, the condition that the content of the video call application is displayed is that the display is in an open screen state, and the display is in the open screen state, which indicates that the display device is not in the speaker mode, or the display device is in the speaker mode but has exited from the speaker mode.

At the moment, the local terminal of the display equipment detects the running state of the camera so as to ensure the normal running of the video call. The operation state comprises an adjustable state and an unadjustable state, wherein the adjustable state indicates that the local terminal of the display equipment is provided with the camera and the camera is in an idle state; the non-invokable state indicates that the local terminal is not configured with a camera, or the camera configured at the local terminal is occupied by other applications or fails, and at this time, the video call application cannot be invoked.

When the running state of the camera is judged to be the calling state, the current display equipment supports the camera and can carry out video call. At this time, the video call application can be started, a video call interface is generated, and the video call interface is displayed in the display.

When the running state of the camera is judged to be the state which can not be called, the fact that no camera exists in the current display equipment or the camera breaks down is shown. At this time, the video call cannot be performed, so in order to prompt the user of the reason that the video call cannot be performed, a camera fault prompt can be generated and displayed in the display to prompt the user to detect the camera, hang up the video call, or switch to the voice call through the UI.

In some embodiments, after the video call is ended, if the display device is originally in the speaker mode, after exiting the video call application, the display device needs to be controlled to re-enter the speaker mode, and the video call application notifies the speaker mode to turn off the screen. And if the display equipment is in the screen-opening state, the video call application directly exits.

Therefore, when the display device provided by the embodiment of the invention starts the designated application, whether the local terminal of the display device is in the sound box mode or not can be judged firstly, if the local terminal of the display device is in the sound box mode, the sound box mode exits firstly, and the designated application is displayed in the display; and when the designated application exits, controlling the display equipment to enter the loudspeaker box mode again. If the local terminal of the display equipment is not in the sound box mode, directly displaying the specified application in the display; and directly quitting the specified application when the specified application finishes running. Therefore, the display equipment can switch the on-off state of the display in time according to the application scene so as to display the application content in the display in time, and the user experience is good.

In some embodiments, when the designated application is a video call application, the peer device that makes a call with the home-end display device may be an intelligent terminal or a display device.
