Detailed Description

In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The present application is not limited to a display device having a dual system and dual display structure as shown in fig. 1 to 7, that is, a display device having a first controller (first hardware system), a second controller (second hardware system), a first display, and a second display, and a display device having a non-dual system, that is, having one controller (hardware system), or having more than two controllers (hardware systems).

In a specific implementation manner of the present application, a display device with dual systems is used to describe the technical solution of the present application. The structure, function, implementation, and the like of the display device having the dual system hardware structure will be described in detail first.

For the convenience of users, various external device interfaces are usually provided on the display device to facilitate connection of different peripheral devices or cables to implement corresponding functions. When a high-definition camera is connected to an interface of the display device, if a hardware system of the display device does not have a hardware interface of a high-pixel camera receiving the source code, data received by the camera cannot be displayed on a display screen of the display device.

Furthermore, due to the hardware structure, the hardware system of the conventional display device only supports one path of hard decoding resources, and usually only supports video decoding with a resolution of 4K at most, so when a user wants to perform video chat while watching a network television, the user needs to use the hard decoding resources (usually GPU in the hardware system) to decode the network video without reducing the definition of the network video screen, and in this case, the user can only process the video chat screen by using a general-purpose processor (e.g. CPU) in the hardware system to perform soft decoding on the video.

The soft decoding is adopted to process the video chat picture, so that the data processing burden of a CPU (central processing unit) can be greatly increased, and when the data processing burden of the CPU is too heavy, the problem of picture blocking or unsmooth flow can occur. Further, due to the data processing capability of the CPU, when the CPU performs soft decoding on the video chat screen, multi-channel video calls cannot be generally implemented, and when a user wants to perform video chat with multiple other users in the same chat scene, access is blocked.

In view of the above aspects, to overcome the above drawbacks, the present application discloses a dual hardware system architecture to implement multiple channels of video chat data (at least one channel of local video).

The concept to which the present application relates will be first explained below with reference to the drawings. It should be noted that the following descriptions of the concepts are only for the purpose of facilitating understanding of the contents of the present application, and do not represent limitations on the scope of the present application.

In various embodiments of the present application, a hardware system may also be referred to as a motherboard (or chip).

Fig. 1 is a schematic diagram illustrating an operation scenario between a display device and a control apparatus. As shown in fig. 1, a user may operate the display apparatus 200 through the control device 100.

The control device 100 may be a remote controller 100A, which can communicate with the display device 200 through an infrared protocol communication, a bluetooth protocol communication, a ZigBee (ZigBee) protocol communication, or other short-range communication, and is used to control the display device 200 in a wireless or other wired manner. The user may input a user instruction through a key on the remote controller 100A, voice input, control panel input, or the like to control the display apparatus 200. Such as: the user can input a corresponding control command through a volume up/down key, a channel control key, up/down/left/right movement keys, a voice input key, a menu key, a power on/off key, etc. on the remote controller 100A to control the functions of the display device 200.

The control apparatus 100 may also be a smart device such as a mobile terminal 100B, a tablet computer, a notebook computer, etc., which may communicate with the display device 200 through a local Network (L AN, &lttttranslation = L "&tttl &ttt/t &gttoral Area Network), a Wide Area Network (WAN, Wide Area Network), a Wireless local Area Network (W L AN, Wireless L oral Area Network), or other Network, and implement control of the display device 200 through AN application program corresponding to the display device 200.

For example, the mobile terminal 100B and the display device 200 may each have a software application installed thereon, so that connection communication between the two can be realized through a network communication protocol, and the purpose of one-to-one control operation and data communication can be further realized. Such as: a control instruction protocol can be established between the mobile terminal 100B and the display device 200, a remote control keyboard is synchronized to the mobile terminal 100B, and the function of controlling the display device 200 is realized by controlling a user interface on the mobile terminal 100B; the audio and video content displayed on the mobile terminal 100B may also be transmitted to the display device 200, so as to implement a synchronous display function.

As shown in fig. 1, the display apparatus 200 may also perform data communication with the server 300 through various communication means. In various embodiments of the present application, the display device 200 may be allowed to be in a wired or wireless communication connection with the server 300 via a local area network, a wireless local area network, or other network. The server 300 may provide various contents and interactions to the display apparatus 200.

In addition, the first display 201 displays the multi-party interactive picture while displaying the traditional television program picture, and the multi-party interactive picture does not block the traditional television program picture. The display mode of the traditional television program picture and the multi-party interactive picture is not limited by the application. For example, the position and the size of the traditional television program picture and the multi-party interactive picture can be set according to the priority of the traditional television program picture and the multi-party interactive picture.

Taking the example that the priority of the traditional television program picture is higher than that of the multi-party interactive picture, the area of the traditional television program picture is larger than that of the multi-party interactive picture, and the multi-party interactive picture can be positioned at one side of the traditional television program picture and can also be arranged at one corner of the multi-party interactive picture in a floating manner.

The display device 200 may be, on one hand, a liquid crystal display, an O L ED (Organic L light emitting diode) display, a projection display device, and on the other hand, a display system consisting of a smart tv or a display and a set-top box, the specific type, size, resolution, etc. of the display device 200 are not limited, and it will be understood by those skilled in the art that the display device 200 may be modified in its performance and configuration as desired.

The display apparatus 200 may additionally provide an intelligent network tv function that provides a computer support function in addition to the broadcast receiving tv function. Such as a network television, a smart television, an Internet Protocol Television (IPTV), etc. In some embodiments, the display device may not have a broadcast receiving television function.

Specifically, the picture shot by the camera may be displayed on the display device in a full screen, a half screen, or in any selectable area.

As an optional connection mode, the camera is connected with the rear shell of the display device through the connecting plate, and is fixedly installed in the middle of the upper side of the rear shell of the display device.

As another optional connection mode, the camera is connected to the rear shell of the display device through a connection board or another conceivable connector, the camera is capable of lifting and descending, a lifting motor is installed on the connector, when a user wants to use the camera or an application program wants to use the camera, the camera is lifted out of the display device, and when the camera is not needed, the camera can be embedded into the rear shell, so that the camera is protected from being damaged, and privacy safety of the user is protected.

As an embodiment, the camera adopted in the present application may have 1600 ten thousand pixels, so as to achieve the purpose of ultra high definition display. In actual use, cameras higher or lower than 1600 ten thousand pixels may also be used.

After the camera is installed on the display device, the contents displayed by different application scenes of the display device can be fused in various different modes, so that the function which cannot be realized by the traditional display device is achieved.

Illustratively, a user may conduct a video chat with at least one other user while watching a video program. The presentation of the video program may be as a background frame over which a window for video chat is displayed. The function is called 'chat while watching'.

Optionally, in a scene of "chat while watching", at least one video chat is performed across terminals while watching a live video or a network video.

In another example, a user can conduct a video chat with at least one other user while entering the educational application for learning. For example, a student may interact remotely with a teacher while learning content in an educational application. Vividly, this function can be called "chatting while learning".

In another example, a user conducts a video chat with a player entering a card game while playing the game. For example, a player may enable remote interaction with other players when entering a gaming application to participate in a game. Figuratively, this function may be referred to as "watch while playing".

Optionally, the game scene is fused with the video picture, the portrait in the video picture is scratched and displayed in the game picture, and the user experience is improved.

Optionally, in the motion sensing game (such as ball hitting, boxing, running and dancing), the human posture and motion, limb detection and tracking and human skeleton key point data detection are obtained through the camera, and then the human posture and motion, the limb detection and tracking and the human skeleton key point data detection are fused with the animation in the game, so that the game of scenes such as sports and dancing is realized.

In another example, a user may interact with at least one other user in a karaoke application in video and voice. Vividly, this function can be called "sing while watching". Optionally, when at least one user enters the application in a chat scenario, multiple users may jointly complete recording of a song.

In another example, a user may turn on a camera locally to take pictures and videos, figurative, which may be referred to as "looking into the mirror".

The application layer 2912 of the first controller 210 may include, but is not limited to, one or more applications such as: a video-on-demand application, an application center, a game application, and the like. The application layer 3912 of the second controller 310 may include, but is not limited to, one or more applications such as: live television applications, media center applications, and the like. It should be noted that what applications are respectively contained in the second controller 310 and the first controller 210 is determined according to the operating system and other designs, and the present invention does not need to make specific limitations and divisions on the applications contained in the second controller 310 and the first controller 210.

The live television application program can provide live television through different signal sources. For example, a live television application may provide television signals using input from cable television, radio broadcasts, 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.

A video-on-demand application may provide video from different storage sources. Unlike live television applications, video on demand provides a video display from some storage source. For example, the video on demand may come from a server side of the cloud storage, from a local hard disk storage containing stored video programs.

The media center application program can provide various applications for playing multimedia contents. For example, a media center, which may be other than live television or video on demand, may provide services that a user may access to various images or audio through a media center application.

The application program center can provide and store various application programs. The application may be a game, an application, or some other application associated with a computer system or other device that may be run on a display device. The application center may obtain these applications from different sources, store them in local storage, and then be operable on the display device 200.

Since the second controller 310 and the first controller 210 may have independent operating systems installed therein, there are two independent but interrelated subsystems in the display apparatus 200. For example, Android (Android) and various APPs may be independently installed on the second controller 310 and the first controller 210, and may all realize a certain function, and the second controller 310 and the first controller 210 cooperate to realize a certain function.

Fig. 9 illustrates a schematic diagram of a user interface in the display device 200. As shown in fig. 9, the user interface includes a first view display area 2011 and a second view display area 2021. The first view display area 2011 and the second view display area 2021 have substantially the same function, and only the first view display area 2011 is described in an important manner below. Illustratively, among other things, the first view display 2011 includes layouts for one or more different items. And a selector indicating that the item is selected is also included in the user interface, and a position of the selector is movable by a user input to change a selection of a different item.

A "user interface" is a media interface for interaction and information exchange between an application or operating system and a user that enables the conversion of the internal form of information to a form acceptable to the user. A common presentation form of a user interface is a Graphical User Interface (GUI), which refers to a user interface related to computer operations and displayed in a graphical manner. It may be an interface element such as an icon, a window, a control, etc. displayed in the display screen of the electronic device, where the control may include a visual interface element such as an icon, a button, a menu, a tab, a text box, a dialog box, a status bar, a navigation bar, a Widget, etc.

In some embodiments, the first view display area 2011 is a scalable view display. "scalable" may mean that the first view display area 2011 is scalable in size or proportion on the screen, and the items in the first view display area 2011 are scalable in size or proportion on the screen.

The "item" is displayed in a view display area of the user interface in the display device 200 to represent a visual object of corresponding content such as an icon, a thumbnail, a video clip, and the like. For example: the items may represent movies, image content or video clips of a television show, audio content of music, applications, or other user access content history information.

Further, the item may represent an interface or a collection of interfaces on which the display device 200 is connected to an external device, or may represent a name of an external device connected to the display device, or the like. Such as: a signal source input Interface set, or a High Definition Multimedia Interface (HDMI), a USB Interface, a PC terminal Interface, and the like.

It should be noted that: the view display area may present Video chat project content or application layer project content (e.g., web page Video, Video On Demand (VOD) presentations, application screens, etc.).

A "selector" is used to indicate where any item has been selected, such as a cursor or a focus object. Positioning the selection information input according to an icon or menu position touched by the user in the display 200 may cause movement of a focus object displayed in the display device 200 to select a control item, one or more of which may be selected or controlled.

The focus object refers to an object that moves between items according to user input. Illustratively, the focus object position is implemented or identified by drawing a thick line through the item edge. In other embodiments, the focus form is not limited to an example, and may be a form such as a cursor that is recognizable by the user, either tangible or intangible, such as in the form of a 3D deformation of the item, or may change the identification of the border lines, size, color, transparency, and outline and/or font of the text or image of the item in focus.

The event transmission system 2914, which may monitor user input for each predefined event or sub-event heard, provides control identifying the event or sub-event directly or indirectly to the interface layout management module 2913.

The interface layout management module 2913 is configured to monitor the state of the user interface (including the position and/or size of the view partition, the item, the focus or the cursor object, the change process, and the like), and according to the event or the sub-event, may perform a modification on the layout of the size and position, the hierarchy, and the like of the view display area, and/or adjust or modify the layout of the size or/and position, the number, the type, the content, and the like of the layout of various items in the view display area. In some embodiments, the layout is modified and adjusted, including displaying or not displaying the view sections or the content of the items in the view sections on the screen.

And a user input interface for transmitting an input signal of a user to the controller or transmitting a signal output from the controller to the user. For example, the control device (e.g., a mobile terminal or a remote controller) may send an input signal, such as a power switch signal, a channel selection signal, a volume adjustment signal, etc., input by a user to the user input interface, and then the input signal is forwarded to the controller by the user input interface; alternatively, the control device may receive an output signal such as audio, video, or data output from the user input interface via the controller, and display the received output signal or output the received output signal in audio or vibration form.

In some embodiments, a user may input a user command on a Graphical User Interface (GUI) displayed on the display 200, and the user input interface receives the user input command through the Graphical User Interface (GUI). Alternatively, the user may input the user command by inputting a specific sound or gesture, and the user input interface receives the user input command by recognizing the sound or gesture through the sensor.

FIG. 10 is a block diagram illustrating a display device presenting dual system dual screens in accordance with an exemplary embodiment; fig. 11 is a block diagram schematically showing the structure of a display device according to an exemplary embodiment. Referring to fig. 10 and 11, the display device provided in the embodiment of the present invention includes two controllers, which are a second controller and a first controller, respectively, where each controller runs an independent Android system, that is, a system N (a second hardware system) runs on the second controller, a system a (a first hardware system) runs on the first controller, the system N is a master system, and the system a is a slave system.

To enable the capabilities of both systems to be exposed to the user, the display device 200 is configured with dual displays. The dual display includes a first display (small screen) 280 and a second display (large screen) 380, the second display 380 (i.e. the first display 201 in fig. 1) is connected to the second controller 310 (system N) for displaying the display content of each application configured in the system N, providing the main tv service; the first display 280 (i.e., the second display 202 in fig. 1) is connected to the camera and the first controller 210 (system a) for displaying the social ability and the auxiliary information prompt to the user. The system A is provided with an application related to the camera, and the system N is provided with other applications for presenting social ability.

The first display 280 is communicatively connected to the first controller 210, the first display 280 is configured to display content of a first application, the first application refers to an application configured in the first controller 210; the second display 380 is communicatively connected to the second controller 310, and the second display 380 is configured to display content of a first application or display content of a second application, which is an application configured in the second controller 310.

The system N and the system A are connected through an HDMI interface, and the switching of the system N and the system A interface can be realized. The two systems can be connected through a data path to realize data transmission between the two systems. Because the system N does not provide social ability, the functions of video chat, magic mirror and the like are configured on the system A, and when a user conducts video chat, the content of the system A is displayed through the second display (large screen) instead of the first display (small screen).

When the user quits the video chat, the display device provided by the embodiment can coordinate and control the two systems, so that the corresponding application content can be accurately displayed on the large screen and the small screen. For example, if the first display previously displayed the home page of system a, the second display previously displayed a video playback, such as a video played by a media center. At this point, the user triggers the display of the first application to be presented on the second display, for example, launching and displaying a "mirror" application in the first controller on the second display. In this scenario, after the user triggers the return key on the remote control, the second display ends displaying the content of the "look at mirror" application, and displays the application before starting the "look at mirror" application, i.e., the homepage of system a, in the first display; the video playback that was displayed prior to the "mirror" application, i.e., the video played by the media center, is displayed in the second display.

In order to implement the video call function of the display device, the display device provided in this embodiment is further configured with a camera, the camera is configured to collect environment image data, and the camera is connected to the system N by default. In order to realize the coordinated switching of the camera between the system N and the system A, the first controller is configured with a camera switching module, a first development encapsulation module (Framework A) and an HDMI Switch module. The camera switching module is connected with the camera, and the camera switching module is connected to the system N by default, namely the camera is connected to the system N by default. When the application in the first controller needs to call the camera, the camera switching module can switch the camera to be connected with the first controller, and the coordinated switching of the camera between the first controller and the second controller is realized. The first controller is configured to control content display of the first display and switching of the camera, the first development packaging module is used for storing a camera application list, and a first application and a second application which need to use the camera are stored in the camera application list; the HDMI Switch module implements a Switch data interface, for example, connecting a display content output interface of an application in a first controller to a first display, or connecting a display content output interface to a second display in a second controller.

In order to ensure that an application configured in a first controller can call a camera, an embodiment of the present invention provides a display device, where a first controller determines whether a camera needs to be used according to an application started by a current display device, and when the camera needs to be used, a camera switching module is controlled to switch the camera from being connected to a second controller to the first controller, and after the application in the first controller calls the camera, the camera switching module is controlled to switch the camera from being connected to the first controller to the second controller, so as to implement real-time switching of the camera along with the started application, so that the application on two systems flexibly calls the camera, and further ensure that the camera can be coordinately switched between the two systems.

Fig. 12 is a first flowchart illustrating a dual system camera switching control method according to an exemplary embodiment; fig. 13 is a first data flow diagram illustrating a dual system camera switching control method according to an exemplary embodiment. Specifically, referring to fig. 12 and fig. 13, in the display device provided in the embodiment of the present invention, when performing the coordinated switching of the cameras, the first controller is configured to execute the method steps shown in fig. 12:

and S11, receiving an application starting instruction for starting the specified application.

The user selects one application to start through the remote controller, namely when the display device starts the designated application, the first controller receives an application starting instruction, and the designated application can be an application configured in the first controller.

And S12, responding to the application starting instruction, acquiring a camera application list, wherein application information needing to use the camera is stored in the camera application list.

Since the second controller is connected with the camera by default, in order to determine whether the camera needs to be switched, whether the specified application started by the first controller is the application which needs to use the camera needs to be judged. Therefore, after receiving the application starting instruction, the first controller immediately acquires the camera application list from the first development packaging module.

The camera application list stores application information which is configured in the display device and needs to use the camera, wherein the application information comprises application information configured in the first controller and application information configured in the second controller, and specifically, the application information can be a name of each application package which needs to use the camera.

And S13, judging whether the designated application is the application needing to use the camera or not based on the camera application list.

To determine whether the specified application is an application that requires the use of a camera, the application package name of the specified application may be obtained. Comparing the application package name of the designated application with each application package name in the camera application list, and if the application package name of the designated application is consistent with one application package name in the camera application list, indicating that the designated application is the application needing to use the camera; if the application package name of the specified application is not consistent with any application package name in the camera application list, the specified application is the application which does not need to use the camera.

Whether the designated application is the application needing to use the camera or not is judged, whether the camera needs to be switched or not can be accurately determined, namely whether the first controller needs to control the camera switching module or not is determined, and the camera is switched to the first controller from the second controller which is connected currently.

And S14, if the designated application is the application needing to use the camera, sending a switching instruction to the camera switching module to switch the connection of the camera from the second controller to the first controller.

After the first controller judges that the designated application is the application needing to use the camera, a switching instruction is generated and sent to the camera switching module, and the camera switching module controls the connection state of the camera, namely, the second controller which is connected currently is switched to be connected with the first controller.

If the designated application is an application which does not need to use the camera, the camera does not need to be switched at the moment, the first controller does not need to control the switching of the camera, and then the connection between the camera and the second controller is maintained.

A flow chart of a method of launching a specified application according to an exemplary embodiment is illustrated in fig. 14. The first controller determines that the started designated application is the application needing to use the camera, so that the camera can be connected with the first controller, and whether the camera is available or not can be detected after the camera needs to be switched. If the camera is being called by other applications, at this time, the switching of the camera cannot be realized.

Therefore, referring to fig. 14, in order to ensure that the camera can be switched to the first controller, the first controller is further configured to perform the following steps on the basis of performing the method steps provided by the foregoing embodiment:

and S15, detecting whether the camera is in an idle state according to a preset detection rule.

And S16, if the camera is in an idle state, establishing connection between the designated application and the camera, and starting the designated application.

Whether the camera is available or not is judged, and the judgment can be carried out by detecting whether the camera is in an idle state or not. The camera can be determined to be available when the camera is in an idle state.

And after the camera is judged to be in an idle state, the camera is connected with the first controller, so that the specified application is applied to the camera for communication, and the specified application calls the camera to realize the starting of the specified application.

In this embodiment, when detecting whether the camera is available, the first controller may perform loop detection according to a preset detection rule. The preset detection rule includes a preset detection duration, and in this embodiment, the preset detection duration may be set to 200ms for one detection.

A flowchart of a method of detecting whether a camera is available according to an exemplary embodiment is illustrated in fig. 15. Referring to fig. 15, in one possible embodiment, in detecting whether the camera is in the idle state, the first controller is further configured to:

s1511, according to the preset detection duration, detecting the use state attribute of the camera.

S1512, if the using state attribute does not meet the preset condition, determining that the camera is in an idle state.

And S1513, if the using state attribute meets the preset condition, determining that the camera is in the using state.

The first controller detects the use state attribute of the camera according to the preset detection time length, wherein the use state attribute can be set when the camera is called, for example, if the camera is called by a certain application, the use state attribute of the camera can be set to sys. Used is set to null if the application disconnects from the camera.

Therefore, when the use state attribute of the camera is detected, whether the application package name calling the camera can be detected or a null value is detected can be judged within 200 ms.

In this embodiment, the preset condition is set to detect the name of the application package calling the camera. If the detected use state attribute of the camera does not meet the preset condition within the preset detection duration, the fact that the name of an application package calling the camera is not detected is indicated, and at the moment, the use state attribute of the camera is a null value, it can be determined that the camera is in an idle state and is not occupied by any application. And after the camera is judged to be in an idle state, the camera is connected with the first controller, so that the specified application calls the camera and communicates, and the specified application is started.

If the detected use state attribute of the camera meets the preset condition, the fact that the first controller detects the name of an application package for calling the camera is indicated, the fact that the camera is currently called by some application and cannot establish communication connection with the specified application is indicated, and the fact that the camera is in the use state can be determined. At this time, the camera cannot be connected with the first controller, that is, the communication connection between the designated application and the camera cannot be realized.

In another possible embodiment, when the display device detects the usage status attribute of the camera, the adopted preset detection rule may include a preset detection duration and a preset detection number. The preset detection times refer to the maximum detection times for detecting the use state attribute of the camera.

Fig. 16 is a flowchart illustrating another method of detecting whether a camera is available according to an exemplary embodiment. Specifically, referring to fig. 16, in the present embodiment, when detecting whether the camera is in the idle state, the first controller is further configured to:

s1521, circularly detecting the using state attribute of the camera according to preset detection time.

S1522, counting the circulation times when the using state attribute of the camera is detected.

S1523, if the using state attribute of the camera is not detected when the circulation times exceed the preset detection times, the camera is determined to be in an idle state.

In this embodiment, the first controller cyclically detects the usage state attribute of the camera according to a preset detection time, such as 200 ms. After the first detection is completed in 200ms, the second detection is performed, and so on.

In order to ensure that the camera can be called by an application (an application configured in the first controller or an application configured in the second controller) of the device to be used in time, the first controller counts the number of times of loop detection, and when the number of times of loop detection exceeds a preset number of times of loop detection, the use state attribute of the camera is still not detected, which indicates that the camera is not called, i.e. the camera is determined to be in an idle state, and the loop detection process can be ended.

For example, the preset detection times may be set to 3 times, if the cycle number when the first controller detects the use state attribute of the camera exceeds 3 times, the use state attribute of the camera is still not detected, it is determined that the camera is in an idle state, and the camera is connected with the first controller, so that the specified application calls the camera and performs communication, and the specified application is started.

For example, take the example of starting a designated application "look at the mirror" of a first controller in a display device. The first controller obtains a camera application list after receiving an application starting instruction for starting the mirror-looking application. Since the "look mirror" application belongs to the camera application list, it can be determined that the "look mirror" application is an application that requires the use of a camera. And the current camera is connected with the second controller by default, so that the camera needs to be switched. The first controller generates a switching instruction and sends the switching instruction to the camera switching module so as to switch the connection of the camera with the second controller to the connection with the first controller. And then, circularly detecting whether the camera is in an idle state or not according to the preset detection time length of 200ms, namely circularly detecting the use state attribute of the camera. When the cycle number of the detection process exceeds the preset detection number, or the use state attribute of the camera meets the preset condition, the camera is determined to be in an idle state, the camera is connected with the first controller, so that the specified application calls the camera to communicate, and the specified application is started. Therefore, when the camera is required to be used by the application in the first controller, the camera is controlled to switch the connection with the second controller to the first controller.

In the case where the designated application started in the display apparatus is an application configured in the first controller and the application needs to use the camera, at this time, the camera switches the connection with the second controller to the first controller, and the display content of the designated application is displayed in the second display (large screen). If the designated application is finished being used, namely after the user clicks the remote controller to control the designated application to return, the HDMI interface of the first controller needs to be switched to the first display (small screen), and at the moment, after the first controller returns from the designated application, the first display needs to call the display content of the previous application started before the designated application is started to display. If the previous application is an application that does not require the use of a camera, the camera will then switch back to the second controller by connecting to the first controller.

Therefore, in this scenario, according to the display device provided by the embodiment of the present invention, after the first controller returns from the designated application to the previous application, the camera is also switched back to the second controller by the first controller, so as to implement coordinated switching of the camera.

Fig. 17 is a second flowchart illustrating a dual system camera switching control method according to an exemplary embodiment; fig. 18 is a second data flow diagram illustrating a dual system camera switching control method according to an exemplary embodiment. Referring to fig. 17 and 18, the display device provided in the present embodiment, when implementing the coordinated switching of the cameras, the first controller is configured to execute the following steps:

and S21, receiving an application return instruction for showing the prior application, wherein the application return instruction is an instruction generated when the specified application returns to the prior application, and the specified application is an application needing to use the camera.

After the display device is exited from the designated application, that is, after the designated content is returned from the first controller, in order to cause the first display to display the corresponding content, the related content of the previous application that was in the activated state before the designated application was activated may be called by the first controller and displayed in the first display.

At the moment, the display device needs to switch the applications, the first development packaging module sends an application return instruction corresponding to the application switching to the first controller, the application return instruction is used for acquiring the display content of the prior application, and the prior application is the application started by the first controller before the specified application is started.

For this purpose, when the user exits the designated application, the first controller receives an application return instruction, so that the starting application of the first controller is returned to the previous application by the designated application.

And S22, responding to the application return instruction, acquiring a camera application list, wherein application information needing to use the camera is stored in the camera application list.

Since the designated application is an application that requires the use of a camera and the first controller is currently connected to the camera, when an application return operation is performed, it is necessary to determine whether or not the previous application is also an application that requires the use of a camera in order to accurately determine whether or not the camera needs to be switched back to be connected to the second controller. Therefore, after receiving the application return instruction, the first controller immediately acquires the camera application list from the first development packaging module.

And S23, judging whether the prior application is the application needing to use the camera or not based on the camera application list.

To determine whether the previous application is an application that requires the use of a camera, the application package name of the previous application may be acquired. Comparing the name of the application package of the prior application with each application package name in the camera application list, and if the name of the application package of the prior application is consistent with one of the application package names in the camera application list, indicating that the prior application is the application needing to use the camera; if the application package name of the prior application is not consistent with any application package name in the camera application list, the prior application is the application which does not need to use the camera.

Whether the prior application is the application needing to use the camera or not is judged, whether the camera needs to be switched or not can be accurately determined, namely whether the first controller needs to control the camera switching module or not is determined, and the camera is switched back to the second controller from the first controller which is connected currently.

And S24, if the prior application is the application which does not need to use the camera, sending a switching instruction to the camera switching module to switch the connection of the camera to the second controller.

The first controller generates a switching instruction after judging that the prior application is the application which does not need to use the camera, and sends the switching instruction to the camera switching module, and the camera switching module controls the connection state of the camera, namely the first controller which is connected at present is switched back to be connected with the second controller.

If the previous application is an application requiring the use of a camera, that is, the application in the first controller requires the use of a camera, and at this time, the camera does not need to be switched, the first controller maintains the connection between the camera and the first controller.

And after the first controller exits the designated application and determines that the called prior application is the application without the camera, at the moment, the camera is connected with the first controller and returns to be connected with the second controller. Therefore, after the camera needs to be switched, the connection between the second controller and the camera needs to be established, and the default connection state of the camera is recovered. If the camera is called by other applications after exiting from the connection with the designated application, at this time, the connection between the camera and the second controller cannot be realized.

A flow chart of a method of generating a switch instruction according to an exemplary embodiment is illustrated in fig. 19. Specifically, referring to fig. 19, the present embodiment provides the display device, wherein the first controller is further configured to:

and S241, acquiring the use state attribute of the camera.

And S242, if the using state attribute does not meet the preset condition, determining that the camera is in an idle state.

And S243, generating a switching instruction based on the idle state, wherein the switching instruction is used for realizing switching of the camera between the first controller and the second controller.

After the first controller judges that the previous application is the application which does not need to use the camera, whether the camera is available or not needs to be judged for ensuring that the camera can be connected with the second controller, and at the moment, the use state attribute of the camera needs to be acquired.

In this embodiment, when determining whether the camera is in the idle state, the specific determination method may refer to the contents of steps S1511 to S1513 in the foregoing embodiment, which is not described herein again.

When the camera is in the idle state, the situation is shown that the camera is not called by other applications after the designated application exits, so that the first controller can generate a switching instruction and send the switching instruction to the camera switching module, the camera switching module controls the connection state of the camera, and the first controller which is connected at present is switched back to be connected with the second controller.

For example, take the example of the display device being returned by a designated application "mirror" to a previous application "small screen home page". After the first controller receives an application return instruction returned by the "look at mirror" application, the application launched by the first controller before launching the "look at mirror" application is a "small screen home page". Since the small-screen homepage application does not belong to the camera application list, the small-screen homepage application can be judged as an application which does not need to use a camera. And the current camera is connected with the first controller by default, so that the camera needs to be switched. The first controller generates a switching instruction and sends the switching instruction to the camera switching module so as to switch the connection of the camera back to the second controller through the first controller. And then, circularly detecting whether the camera is in an idle state or not according to the preset detection time length of 200ms, and if the camera is determined to be in the idle state, establishing connection between the camera and the second controller to enable the camera to be restored to the called state. Therefore, when the application in the first controller does not need to use the camera, the camera is controlled to switch the connection with the first controller to the second controller.

As can be seen from the foregoing technical solutions, in the display device provided in the embodiments of the present invention, the first controller receives an application start instruction for starting a specific application; and after the designated application is judged to be the application needing to use the camera, sending a switching instruction to the camera switching module so as to switch the connection of the camera from the second controller to the first controller. After the designated application exits, generating an application return instruction when the designated application returns to a previous application, and receiving an application return instruction for showing the previous application by the first controller; and if the prior application is judged to be the application which does not need to use the camera, sending a switching instruction to a camera switching module so as to switch the connection of the camera to the second controller. Therefore, according to the display device provided by the embodiment of the invention, the first controller controls the camera to switch the connection with the second controller to the first controller by controlling the camera switching module when the application in the first controller needs to use the camera, and controls the camera to switch the connection with the first controller to the second controller when the application in the first controller does not need to use the camera, so that the camera is switched in real time along with the started application, the application in the dual systems can flexibly call the camera, and the camera can be coordinated and switched between the two systems.

Fig. 12 is a first flowchart illustrating a dual system camera switching control method according to an exemplary embodiment. Referring to fig. 12, a dual-system camera switching control method provided in an embodiment of the present invention is executed by a first controller, and the method includes the following steps:

s11, receiving an application starting instruction for starting the specified application;

s12, responding to the application starting instruction, acquiring a camera application list, wherein application information needing to use a camera is stored in the camera application list;

s13, judging whether the specified application is an application which needs to use a camera or not based on the camera application list;

and S14, if the specified application is an application which needs to use the camera, sending a switching instruction to the camera switching module so as to switch the connection of the camera from the second controller to the first controller.

Further, the method further comprises: detecting whether the camera is in an idle state or not according to a preset detection rule; and if the camera is in an idle state, establishing connection between the specified application and the camera, and starting the specified application.

Further, the detecting whether the camera is in an idle state according to a preset detection rule includes: detecting the use state attribute of the camera according to the preset detection duration; if the using state attribute does not meet the preset condition, determining that the camera is in an idle state; and if the using state attribute meets a preset condition, determining that the camera is in a using state.

Further, the detecting whether the camera is in an idle state according to a preset detection rule includes: circularly detecting the use state attribute of the camera according to the preset detection duration; counting the cycle times when the using state attribute of the camera is detected; and if the service state attribute of the camera is not detected when the cycle times exceed the preset detection times, determining that the camera is in an idle state.
