In some embodiments, to enhance the functionality of the display device, a speaker mode may be configured for the display device. The sound box mode belongs to a mode after screen closing, and unlike the common mode, the television screen is closed, but the host still operates. The screen can be quickly switched on and off in the loudspeaker box mode, and user experience is improved.

In some embodiments, the speaker mode is generally configured in the Flow layer of the system, which is inconvenient if the speaker mode needs to be upgraded after a problem occurs. Therefore, the sound box mode configured in the display equipment provided by the embodiment of the invention concentrates main services of the sound box mode on an application layer, and if problems occur, the self-upgrading of the application can be performed without the upgrading of the whole machine, thereby being more convenient and efficient.

The sound box mode refers to that after the display device is turned off, the controller of the display device is still in an operation state, so that the display device can still normally respond to control instructions and still has a voice function, the display device in the sound box mode is used as an intelligent sound box, and a user can enjoy most of services (except watching videos) in a common television mode in the sound box mode, such as services related to the voice function. The display device enters the sound box mode, so that electric quantity can be saved, the influence of long-term watching of television by children on eyesight can be avoided, and user experience is improved.

In some embodiments, a sound box mode adopted by the display device provided by the embodiment of the present invention uses the overall flow: the user triggers a condition to enter the speaker mode (off screen). Loading a cut scene, and judging whether the current service scene is a non-breaking scene or not; if the current service scene is a non-breaking scene, the music is not stopped (the current non-breaking scene comprises QQ music, a media center, hi music and a music screen-throwing application); if the current service scene is a break scene (if the current scene is a video playing page under a JUUI), a transition broadcast needs to be sent, and the system sound is muted. The sending of the sound box mode broadcast is entered, the rest of the applications cannot make sound under the off-screen (notification center, etc.), and the keys (such as set key, signal source key) are shielded. In the speaker mode, a user may interact with the display device in voice. And when other applications need to use the display, exiting the sound box mode and opening the display.

Fig. 6 illustrates an overall architectural diagram of a speaker mode according to some embodiments. Referring to fig. 6, among the complete machine applications configured in the display device, applications that may trigger the display device to enter a speaker mode include, but are not limited to: DMP (media center), hi music, video call, power key (Power key), voice, etc. In the sound box mode, a shutdown selection interface, overlong animation, a media resource framework, equivalent and voice skills and the like can be provided. The shutdown selection interface depends on the whole machine attribute so as to determine whether the interface needs to be displayed and options needing to be displayed in the interface.

When any application is triggered, the system driving layer can control the Flow light effect/screen closing/screen opening/screen closing interface packaging layer. When the shutdown selection interface is presented in the display, options such as a screen-off, shutdown, restarting and the like are presented in the shutdown selection interface, and a user can trigger one of the options through the remote controller so that the display equipment executes corresponding functions. When the cut scene is required to be displayed, the local display equipment sends the cut scene and a media resource request to the cloud server, and the cloud server returns corresponding data to be displayed in a display.

When the display device is controlled to enter the sound box mode in a voice mode, a user inputs a voice command, such as 'enter the sound box mode', and at the moment, the display device responds to the voice command to display the cut scene in the display. The cut scene is a randomly displayed picture, and the pictures displayed each time are different. In the process of displaying the cut scene, voice broadcasting can be further carried out, the voice broadcasting content is related content describing how to use voice instructions in a sound box mode, if the voice broadcasting content is "the screen is about to be closed, you can wake me in a mode shown by pictures".

The scene cut has the display timeliness, and when the scene cut is displayed, the countdown is synchronously displayed, and can be set to 5 seconds, and specifically can be determined according to the broadcasting content, the background operation is supported, and the user experience is improved for each series of machines. And the broadcast voice supports voiceprint, the user can customize the broadcast voice in the setting- > AI- > voice broadcast voice, for example, the broadcast voice can be male mandarin, female cantonese, female Sichuan, male Hunan, and the like.

Fig. 7 illustrates a flow chart of a display device entering a speaker mode according to some embodiments. Referring to fig. 7, the mode of entering the speaker mode (off-screen) is mainly Power key, voice, speaker screen saver, hi music/DMP off-screen, etc. When the display device is controlled to enter the sound box mode, a standby selection option, such as a "screen off" option, needs to be turned on in the system setting in advance. When the user triggers the Power key, a shutdown selection interface is started, at this time, options such as 'screen closing', 'shutdown', 'restarting', 'artistic gallery' are displayed in the shutdown selection interface, and the user selects the 'screen closing' option through the remote controller, so that the display device can enter a sound box mode.

The display device determines whether the current service scene is a service non-breaking scene, if not, for example, if the current scene is a homepage or the television is playing video, the current service is broken by transition. Meanwhile, a cut scene page is started, countdown is started, and voice broadcasting is performed. And when the loudspeaker box needs to enter a loudspeaker box mode, a screen closing interface is called to close the screen. The service non-break scene generally refers to a music play class scene, and the remaining scenes may be service break scenes.

When the user makes the display device enter the sound box mode through the voice/sound box screen protection mode, the user can directly make the display device enter the sound box mode through the voice mode without depending on the steps. If the user controls the display device to enter the sound box mode through Hi music or a DMP screen closing mode, the media center (DMP) screen closing can listen to the song, and the scene is not interrupted for the service currently, so that the screen can be closed directly.

After the display equipment turns off the screen, the screen turning-off attribute can be synchronously set, namely, the system attribute value is set to be 1, and the sound box mode is indicated to be entered; and setting the system attribute value to 0, and indicating that the sound box mode is not entered and the sound box is in an open screen state. When judging whether to need transition, according to the current service scene, if the current service scene is a service non-breaking scene, the transition is not needed, and the screen is directly turned off; if the current service scene is a service interruption scene, a transition is needed, and screen closing is completed after the transition. The transition operation refers to an action of switching signal sources, such as cutting off a video being played.

In some embodiments, when it is desired that the display device exit the speaker mode, an on-screen broadcast needs to be sent by the application that triggers the exit from the speaker mode (on-screen).

Fig. 8 illustrates a flow chart of a display device exiting a speaker mode, according to some embodiments. Referring to fig. 8, applications that trigger exit from speaker mode (open screen) include, but are not limited to, infrared voice, back key, home key, power key; a voice; pushing the bright screen; one touch instant broadcasting; video call, etc. After receiving the open screen broadcast, the loudspeaker box mode application judges whether the current scene is a business non-breaking scene; if the service is not interrupted, setting the current mode as a common television mode; if the service is interrupted, a transition broadcast needs to be sent, a network television mode is pulled up, and a network television homepage is displayed. And sending a broadcast notice to each application, calling a screen opening interface to control the screen opening of the display when the sound box mode is currently exited.

When the display equipment enters a sound box mode, the display is in a screen-closing state; if the normal television function of the display device is to be used again, the display device needs to exit the sound box mode, and the display is controlled to be in a screen-on state. Therefore, a fast switch screen can be realized, and in order to improve user experience, the switch screen state of the display in the sound box mode needs to be switched fast. The display device is only different in the state of the switch screen of the display when entering the sound box mode or exiting the sound box mode, and other states are the same, for example, the host is always in an operating state, and can normally respond to control instructions and the like.

FIG. 9 illustrates a first flowchart of a method of automatically switching a screen in a speaker mode, according to some embodiments; fig. 10 illustrates a first data flow diagram of a method of automatically switching a screen in a speaker mode according to some embodiments. An embodiment of the present invention provides a display apparatus including: a display configured to present a user interface; a controller coupled to the display, the controller being configured to perform the following steps when performing the method of automatically switching the screen in the speaker mode shown in fig. 9 and 10:

s11, judging whether the local end of the display device is in a sound box mode or not in response to a display calling instruction sent by a designated application, wherein the designated application is an application which needs to present content in a display when running, and the sound box mode is a mode that a controller of the display device is in a running state and the display is in a screen closing state.

An application configured in a display device, when running, needs to invoke a display, i.e. to expose the content of the application in the display. For this reason, it is necessary that the display should be in an open screen state while running the application.

And if the display equipment enters the sound box mode, the display is in a screen-off state at the moment. Therefore, in order to accurately determine whether the content of the application can be displayed in the display in time, whether the local end 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 in a screen opening state or a screen closing state is judged.

The appointed application for calling the display is an application which needs to present the content in the display when running, therefore, when the appointed application is triggered, a display calling instruction is generated to call the display, and the display of the corresponding content is realized.

The display call instruction may be generated by triggering a native terminal complete machine application, e.g., DMP, hi music, video call, etc. In one implementation scenario, if the local receives a video call request from the peer, a display call instruction may be generated by the local video call application.

In some embodiments, the controller, upon receiving a display call instruction sent by the specified application, is further configured to:

And 1111, when the appointed application is a video call application, receiving a video call request sent by the opposite terminal equipment 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 appointed application is a video call application, the opposite terminal user wants to carry out video call with the local terminal user, the opposite terminal user operates the opposite terminal equipment used by the opposite terminal user, the video call application configured in the opposite terminal equipment is started, a video call request is generated, and the video call request is sent to the local terminal display equipment.

After receiving the video call request, the local display device can start the video call application configured by the local terminal, and when the local video call application is started, the local display device judges that the application needs to call the display, so that a display call 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 triggering the video call application to generate the video call request by the intelligent terminal may refer to the implementation process of the subsequent steps S31 to S33, and the process of triggering the video call application to generate the video call request by the opposite-end display device may refer to the implementation process of the subsequent steps S21 to S23, which are not described herein in detail.

In some embodiments, if the specific application started by the local terminal is DMP, hi music, or the like, no opposite terminal device exists in this scenario, and therefore, the display call instruction may be synchronously generated according to the starting instruction of the specific application of the local terminal.

After the display calling instruction is generated, in order to accurately determine whether the specified application can directly call the display or not so as to timely display the content of the specified application in the display, 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 in an open screen state or in a closed screen state is judged.

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

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

Step 1122, if the system attribute value of the local end of the display device is 1, it is determined that the local end of the display device is in the speaker mode.

Step 1123, if the system attribute value of the local end of the display device is 0, determining that the local end of the display device is not in the sound box mode.

Based on the foregoing embodiment, whether the home terminal is in the speaker mode is determined by acquiring the attribute value (sys.tvbox.state) of the home terminal, and if the attribute value sys.tvbox.state of the home terminal is 1, it is determined that the home terminal is in the speaker mode. If the system attribute value sys.tvbox.state of the local terminal is 0, the local terminal is determined not to be in the sound box mode.

When in the speaker mode, the designated application needs to be lit up at this time, for example, to make a video call for both users (open screen). At this time, the local user can answer the video call when the local user is convenient, and the hanging-up is inconvenient to select at any time. When the display device is not in the sound box mode, the display device of the display device at the home end is in the open screen state, so that the content of the appointed application can be directly displayed, for example, a video call interface can be directly displayed.

And S12, when the display equipment is in the sound box mode, switching the use state of the display to be in the screen-on state so as to enable the display equipment to exit the sound box mode, presenting the content of the appointed application in the display in the screen-on state, and after the operation of the appointed application is finished, switching the use state of the display to be in the screen-off state so as to enable the display equipment to enter the sound box mode.

When the designated application is started, if the display device is in the sound box mode, the display is in the off-screen state. In order to facilitate the timely display of the content of the appointed application, the display equipment needs to be controlled to exit the sound box mode first, and the display is informed of switching the use state, namely, the use state of the display is switched from the screen closing state to the screen opening state.

After the switching of the open screen state is completed, the display is on screen, and the content of the appointed application can be presented in the display in the open screen state.

In some embodiments, after the designated application completes running, if the display device is originally in the speaker mode, the designated application is exited, and the display device needs to be controlled to enter the speaker mode again.

At this time, when the application is specified to be exited, an application exit instruction is generated, and the local terminal responds to the application exit instruction and switches the use state of the display from the on-screen state to the off-screen state, so that the local terminal enters the sound box mode again.

Therefore, after the display device enters the sound box mode, when the application needs to open the screen, the sound box mode is notified to automatically open the screen. And after the current service is executed, closing the screen again.

And S13, when the local end of the display equipment is not in the sound box mode, the content of the appointed application is presented in the display in the open screen state, and after the operation of the appointed application is finished, the display of the content of the appointed application in the display is canceled.

When the appointed application is started, if the local end of the display device is not in the sound box mode, the display is in the open screen state. Thus, the content of the specified application may be directly presented in the display.

After the appointed application finishes running, the display equipment is in a non-sound box mode, so that after the appointed application exits, the appointed application is directly exited without switching the sound box mode, namely, the display of the content of the appointed application in the display is canceled.

In some embodiments, if the application is designated as a video call application, for example, when a video call is performed with a television through a mobile phone (television), the local screen needs to be turned on to perform the video call, and the video call application notifies the speaker mode.

When the video call application is running, the display device is required to be provided with a camera if the video call interface is to be displayed. Therefore, after the home terminal is on, the condition of the camera needs to be detected, so that the content of the video call application can be displayed in the display.

In some embodiments, the controller, in executing rendering the content of the specified application on the display in the on-screen state, is further configured to:

step 141, detecting an operation state of the camera when the designated application is a video call application and the display is in a screen-on state, wherein the screen-on 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 a callable state, displaying a video call interface generated by the video call application in running in a display.

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

When the application is designated as the video call application, the condition for displaying the content of the video call application 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 sound box mode, or that the display device is in the sound box mode but has exited the sound box mode.

At this time, the display device detects the running state of the camera to ensure the normal running of the video call. The running state comprises a callable state and a non-callable state, wherein the callable state indicates that the local end of the display device is provided with a camera, and the camera is in an idle state; the non-callable state indicates that the local terminal is not configured with a camera, or that the camera configured by the local terminal is occupied by other applications or fails, and at this time, the video call application cannot be called.

And when the running state of the camera is judged to be a callable state, the camera is supported by the current display equipment, and video call can be carried out. At this time, the video call application may be started, and a video call interface may be generated, and the video call interface may be displayed in the display.

And when judging that the running state of the camera is the non-callable state, indicating that the current display equipment has no camera or the camera fails. At this time, the video call cannot be performed, so, to prompt the user that the video call cannot be performed, a camera failure prompt may be generated, and the camera failure prompt is displayed in the display, so as to prompt the user to detect the operation such as the camera, hang up the video call, or switch to the voice call through the UI.

In some embodiments, if the display device is in the speaker mode after the video call is ended, the video call application needs to control the display device to reenter the speaker mode after exiting the video call application, and notifies the speaker mode to turn off the screen. If the display device is in the open screen state, the video call application directly exits.

Therefore, when the display equipment provided by the embodiment of the invention starts the appointed application, whether the local end of the display equipment is in the sound box mode can be judged first, if the local end of the display equipment is in the sound box mode, the sound box mode is exited first, and the appointed application is displayed in the display; and when the appointed application exits, controlling the display device to enter the sound box mode again. If the local end of the display equipment is not in the sound box mode, directly displaying the appointed application in the display; and directly exiting the designated application when the designated application completes running. Therefore, the display device can switch the on-off screen state of the display in time according to the application scene, 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 communicates with the home display device may be an intelligent terminal or a display device.
