Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, 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 some embodiments of the present application, but not all 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 terms "first," "second," and the like in the description, in the claims, and in the drawings of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

The present application is mainly directed to a display device having a dual-system and dual-display structure, that is, a sound and picture synchronization process of a display device having a first controller (a first hardware system), a second controller (a second hardware system), a first display and a second display, and the following first describes details of the structure, function, implementation, and the like of the display device having the dual-system hardware structure.

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. In some embodiments, 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 at the same time, a situation of access blocking may occur.

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.

The term "module," as used in various embodiments of the present application, may refer to any known or later developed hardware, software, firmware, artificial intelligence, fuzzy logic, or combination of hardware and/or software code that is capable of performing the functionality associated with that element.

The term "remote control" as used in the embodiments of the present application refers to a component of an electronic device (such as the display device disclosed in the present application) that is capable of wirelessly controlling the electronic device, typically over a short distance. The component may typically be connected to the electronic device using infrared and/or Radio Frequency (RF) signals and/or bluetooth, and may also include functional modules such as WiFi, wireless USB, bluetooth, motion sensors, etc. For example: the hand-held touch remote controller replaces most of the physical built-in hardware in the common remote control device with the user interface in the touch screen.

The term "gesture" as used in the embodiments of the present application refers to a user behavior used to express an intended idea, action, purpose, or result through a change in hand shape or an action such as hand movement.

The term "hardware system" used in the embodiments of the present application may refer to a physical component having computing, controlling, storing, inputting and outputting functions, which is formed by a mechanical, optical, electrical and magnetic device such as an Integrated Circuit (IC), a Printed Circuit Board (PCB) and the like. 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 according to an embodiment. 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 device 100 may also be an intelligent device, such as a mobile terminal 100B, a tablet computer, a notebook computer, and the like, which may communicate with the display device 200 through a Local Area Network (LAN), a Wide Area Network (WAN), a Wireless Local Area Network (WLAN), or other networks, and implement control of the display device 200 through an application program corresponding to the display device 200. For example, the display device 200 is controlled using an application program running on the smart device. The application may provide various controls to the User through an intuitive User Interface (UI) on a screen associated with the smart device.

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.

Illustratively, the display device 200 receives software Program updates, or accesses a remotely stored digital media library by sending and receiving information, and Electronic Program Guide (EPG) interactions. The servers 300 may be a group or groups, and may be one or more types of servers. Other web service contents such as a video on demand and an advertisement service are provided through the server 300.

The display device 200 includes a first display screen 201 and a second display screen 202, where the first display screen 201 and the second display screen 202 are independent from each other, and a dual hardware control system is adopted between the first display screen 201 and the second display screen 202.

The first display 201 and the second display 202 may be used to display different display screens. For example, the first display screen 201 may be used for screen display of conventional television programs, and the second display screen 202 may be used for screen display of auxiliary information such as notification type messages, voice assistants, and the like.

In some embodiments, the content displayed on the first display screen 201 and the content displayed on the second display screen 202 may be independent of each other. For example, when the first display screen 201 plays a television program, the second display screen 202 may display information such as time, weather, temperature, a reminder message, and the like, which are not related to the television program.

In some embodiments, there may also be an association between the content displayed by the first display screen 201 and the content displayed by the second display screen 202. For example, when the first display screen 201 plays a main screen of a video chat, the second display screen 202 may display information such as a head portrait, a chat duration, and the like of a user currently accessing the video chat.

In some embodiments, some or all of the content displayed by the second display screen 202 may be adjusted to the first display screen 201. For example, the information such as time, weather, temperature, and reminder message displayed on the first display 201 may be adjusted to be displayed on the first display 201, while other information is displayed on the second display 202.

In addition, the first display screen 201 displays a multi-party interactive picture while displaying a 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, for example, a liquid crystal display, an oled (organic Light Emitting diode) display, or a projection display device; on the other hand, the display device can be a display system consisting of an intelligent television or a display and a set-top box. The specific display device type, size, resolution, etc. are not limiting, and those skilled in the art will appreciate that the display device 200 may be modified in 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. Examples include a web tv, a smart tv, an Internet Protocol Tv (IPTV), and the like. In some embodiments, the display device may not have a broadcast receiving television function.

As shown in fig. 1, a camera may be connected or disposed on the display device 200, and is used to present a picture taken by the camera on a display interface of the display device or other display devices, so as to implement interactive chat between users. Specifically, the picture shot by the camera can be displayed on the display device in a full screen mode, a half screen mode or any optional area.

As a connection mode in some embodiments, the camera is connected with the rear shell of the display device through the connection board, and is fixedly installed in the middle of the upper side of the rear shell of the display device.

As another way of connection in some embodiments, the camera is connected to the rear housing of the display device through a connection board or other conceivable connector, which is capable of being lifted up and down, and the connector is provided with a lifting motor, and when the user wants to use the camera or has an application program to use the camera, the camera is lifted up from the display device, and when the user does not need to use the camera, the camera can be embedded in the rear housing, so that the camera is protected from being damaged and the privacy security 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'.

In some embodiments, in a "chat while watching live video or network video" scenario, at least one video chat is conducted across the terminals.

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".

In some embodiments, a game scene is fused with a video picture, a portrait in the video picture is scratched and displayed in the game picture, and user experience is improved.

In some embodiments, in a motion sensing game (such as a ball hitting game, a boxing game, a running game, a dancing game and the like), the posture and the motion of a human body, the detection and the tracking of limbs and the detection of key point data of human skeleton are obtained through a camera, and then the detection and the fusion with animation in the game are carried out, 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". In some embodiments, 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".

In other examples, more or less functionality may be added. The function of the display device is not particularly limited in the present application.

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 an operating system and other designs, and the application does not need to be specifically limited and divided to 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.

A schematic diagram of a user interface in a display device 200 according to an exemplary embodiment is illustrated in fig. 9. As shown in fig. 9, the user interface includes a first diagram display area 2011 and a second diagram display area 2021.

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 device 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, the user may input a user command at a user interface displayed on the display device 200, and the user input interface receives the user input command through the user interface. 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.

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.

Based on the display device 200 described in the above embodiment, in a possible implementation manner, the display device 200 further includes a voice collecting apparatus.

In some embodiments, the voice collecting device may be a microphone array corresponding to the display device 200, and the microphone array is connected to the first controller 210.

In some embodiments, the voice collecting device may also be a microphone 141 on the control device 100 corresponding to the display device 200. The control apparatus 100 may transmit the collected voice information to the first controller 210 through the communicator 130.

Referring to fig. 10, fig. 10 is a first functional configuration diagram of a display device of the first controller 210 and the second controller 310 according to an embodiment of the present disclosure.

In this embodiment, the first controller 210 is configured to receive a voice wake-up command, and send the voice wake-up command to the second controller 310; the second controller 310 is configured to control the second display screen 380 to display a voice input interface according to the voice wake-up instruction; after the second display screen 380 displays the voice input interface, the first controller 210 is configured to receive the first voice information collected by the voice collecting device and recognize the first voice information. After recognizing the first voice message, the first controller 210 sends the recognition result to the second controller 310, and the second controller 310 controls the second display 380 to display the recognition result.

In some embodiments, the first controller 210 obtains target display data requested by the first voice message and sends the target display data to the second controller 310; the second controller 310 is configured to parse the target display data, determine items included in the target display data, and control the second display screen 380 to display each item in a list when two or more items are included in the target display data.

In this embodiment, the first display screen 280 is used for displaying a first user interface, and the first user interface does not refer to a specific interface, but is a generic name of a class of interfaces, which is used for distinguishing the user interfaces displayed in the second display screen 380. Typically, the first user interface is a page associated with a primary function of the display device 200, such as displaying a television program, video, game, etc. The second display screen 380 is used for displaying a second user interface, which is a page related to some auxiliary functions of the display device 200, such as displaying a reminder message, a push message, time, weather, a chat message, and the like.

Illustratively, a user may conduct a video chat with at least one other user using the second display screen 380 while viewing a video program using the first display screen 280. The function is called 'chat while watching'.

In this embodiment, the second user interface further includes some user interfaces triggered by the voice function of the display device, and may include all or part of interfaces from the start to the end of the voice function.

In some embodiments, after the first controller 210 acquires the first voice information, the first voice information may be sent to the server 300, and after the server 300 performs voice recognition on the first voice information, the target display content related to the voice recognition result is found according to the voice recognition result, and is sent to the first controller 210.

In a possible implementation manner, after acquiring the target display data requested by the first voice message, the first controller 210 sends the target display data to the second controller 310; the second controller 310 is configured to parse the target display data and determine items included in the target display data; when two or more items are included in the target display data, the second display screen 380 is controlled to display the respective items in a list.

Here, the "item" may be understood as a visual object in the second display screen 380 to represent 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.

In addition, after performing the voice recognition on the first voice information, the server 300 may further send the voice recognition result to the first controller 210, after receiving the voice recognition result, the first controller 210 sends the voice recognition result to the second controller 310, and the second controller 310 controls the second display screen 380 to display the voice recognition result.

It is understood that, in another possible implementation manner, after the first controller 210 acquires the first voice information, it may recognize the first voice information by using a self-configured voice recognition module, and then send a voice recognition result to the server 300, and the server 300 searches for the target display content related to the voice recognition result according to the voice recognition result.

In addition, after the first controller 210 performs voice recognition on the first voice information by using the voice recognition module configured by itself, the voice recognition result may be directly sent to the second controller 310, and the second controller 310 controls the second display screen 380 to display the voice recognition result.

In one possible embodiment, after the second display screen 380 displays the voice input interface, the microphone array corresponding to the display device may be turned on, the voice uttered by the user may be collected, and the collected voice may be transmitted to the first controller 210.

In another possible embodiment, after the second display screen 380 displays the voice input interface, if the first controller detects a capture instruction triggered by the control apparatus 100, the first voice information sent by the user may be captured by the microphone 141 on the control apparatus 100, and at this time, the microphone array corresponding to the display device 200 is in the off state.

For example, when the user wants to input voice information through the microphone 141 of the control device 100, the user may continuously press the voice input key on the control device 100, then send voice to the microphone 141 of the control device 100, and after the voice is over, release the voice input key, and then the control device 100 transmits the first voice information collected during the pressing of the voice input key to the first controller 210.

In some embodiments, a far-field sound pickup module (not shown) may be disposed on the display device 200, and the far-field sound pickup module can collect the voice of the user from a long distance without the user pressing the microphone 141 on the control apparatus 100 to pick up the sound.

It can be understood that, in this embodiment of the application, the voice collecting device may also be connected to the second controller 310, and send the collected voice information to the second controller 310, and the second controller 310 performs related processing on the voice information, and the specific processing manner may refer to the processing manner of the first controller 210, and is not described herein again.

In some embodiments, when a user needs to perform voice interaction with the display device 200, a voice wake-up instruction may be sent to the display device 200 in a preset wake-up manner.

For example, in one possible implementation, the user may trigger a voice interaction key in the control apparatus 100 to send a voice wake-up instruction to the display device 200. The first controller 210 may be configured to receive a key signal sent by the control apparatus 100 corresponding to the display device 200, and analyze the received key signal, and when the received key signal is generated by triggering of a voice interaction key preset in the control apparatus 100, the first controller 210 may confirm that the voice wake-up instruction is received.

In another possible embodiment, the user may send a voice wake-up instruction to the display apparatus 200 by uttering a preset wake-up keyword, such as "hi spotlight" or the like, to the voice capturing device of the display apparatus 200. The first controller 210 may be configured to receive voice information acquired by the voice acquisition device, recognize the voice information, and when it is determined that a recognition result of the voice information includes a preset wake-up keyword, the first controller 210 may confirm that the voice wake-up instruction is received.

It is understood that, in this embodiment of the application, the second controller 310 may also be configured to receive a key signal sent by the control apparatus 100 corresponding to the display device 200, analyze the received key signal, and confirm that the voice wake-up instruction is received when the received key signal is generated by triggering a voice interaction key preset in the control apparatus 100. In addition, the second controller 310 may be further configured to receive voice information collected by the voice collecting device, recognize the voice information, and confirm that the voice wake-up instruction is received when it is determined that a recognition result of the voice information includes a preset wake-up keyword.

For better understanding of the present embodiment, referring to fig. 11a to 11d, fig. 11a to 11d are schematic diagrams of voice interaction of a display device in the embodiment of the present application.

As shown in fig. 11a, before the voice interaction is performed, the second display screen 380 displays a standby interface 1101, a pre-designed voice assistant image can be displayed in the standby interface 1101, the voice assistant can be regarded as a voice interaction partner which can be seen at any time, and in various scenes, the voice assistant can always wait for a conversation with the user.

When a user needs to perform voice interaction with the display device 200, a voice wake-up instruction may be sent to the display device 200 in a preset wake-up manner. For example, in one possible embodiment, the user may speak a preset wake-up keyword, such as "hi george", or the like, by means of the speech detection device of the display device 200; at this time, the voice collecting device of the display apparatus 200 sends the collected voice information to the first controller 210, the first controller 210 recognizes the received voice information, if the recognition result includes the above-mentioned wake-up keyword, a voice wake-up instruction is sent to the second controller 310, and the second controller 310 controls the second display screen 380 to switch from the standby interface 1101 to the voice input interface 1102 according to the voice wake-up instruction, as shown in fig. 11 b.

In some embodiments, after the second display screen 380 is switched from the standby interface 1101 to the voice input interface 1102, a reminding message for reminding the user that the display device 200 has entered the voice interaction state may be displayed, for example, "what help you need? ".

When the second display screen 380 is switched from the standby interface 1101 to the voice input interface 1102, the voice collecting device starts to collect voice information input by the user and sends the collected voice information to the first controller 210.

For example, in one possible implementation, the user may say "find a hot show" through a microphone of display device 200; at this time, the microphone of the display device 200 may transmit the collected voice information to the first controller 210. After receiving the voice message, the first controller 210 recognizes the voice message and sends the recognition result to the second controller 310, and the second controller 310 controls the second display screen 380 to display the recognition result "find the hot-air program" on the voice input interface 1102, as shown in fig. 11 c.

Meanwhile, the first controller 210 obtains display data related to the voice message and sends the display data to the second controller 310. For example, in a possible implementation, the first controller 210 sends the voice message "find a hot broadcast program" to the server 300, the server 300 finds a program n before the broadcast hotness ranking in the preset video program database, and then sends the broadcast link and the related introduction information of the found program to the first controller 210.

After receiving the target display data transmitted by the first controller 210, the second controller 310 parses the target display data and determines items included in the target display data. For example, in one possible implementation, the second controller 310 classifies the received target display data into a category, and classifies the broadcast link and related introduction information of the same program as one item.

As shown in fig. 11d, when two or more items are included in the target display data, the second controller 310 may control the second display screen 380 to display the respective items 1103 in a list manner; when only one item is included in the target display data, the second controller 310 may directly control the second display screen 380 to display the item.

In addition, the second controller 310 displays a selector 1104 at the same time as the above items, and the selector 1104 may randomly select any one item in the second display screen 380 in an initial state. In some embodiments, the item selected by the selector 1104 in the initial state may be the leftmost displayed item in the second display 380.

In some embodiments, during the voice interaction, the first display 280 may be used for playing a movie image, a game image, etc., or may be in a screen-saving state. That is, the entire voice interaction is displayed on the second display screen 380 and does not affect the content displayed on the first display screen 280.

The display device 200 provided in the embodiment of the present application is further provided with a second display screen 380 and a second controller 310 for controlling the second display screen 380, in addition to the first display screen 280 and the first controller 210 for controlling the first display screen 280, when the display device 200 performs voice interaction, the voice interaction process and the target display data can be displayed through the second display screen 380, so that the influence of the voice interaction process on the normally played content in the first display screen 280 can be avoided.

Based on the description of the above embodiments, in a possible embodiment, the first controller 210 is further configured to:

receives a selection control command and transmits the selection control command to the second controller 310.

The second controller 310 is further configured to:

the selector is controlled to switch between the various items displayed in the second display screen 380 based on the selection control instructions described above.

In this embodiment, when the target display data includes two or more items and the second display screen displays each item in a list, the user may adjust the position of the selector by using the remote control device corresponding to the display device, so that the selector selects the item to be opened.

For example, assuming that the second display screen 380 displays the respective items in a row, the user may move the selector between two adjacent items left and right by activating the "left" and "right" keys in the control apparatus 100 corresponding to the display device 200.

In some embodiments, the first controller 210 receives a selection control command transmitted by the control apparatus 100 corresponding to the display device 200 and transmits the selection control command to the second controller 310. The second controller 310 recognizes the received selection control command and controls the selector to switch between the various items displayed in the second display screen 380.

Illustratively, when the selection control instruction received by the second controller 310 is "next item", the control selector switches to the next item of the currently selected items; when the selection control command received by the second controller 310 is "previous item", the control selector switches to the previous item of the currently selected item.

In this embodiment, when the user wants to open the currently selected item of the selector, the confirmation control instruction may be triggered to open the currently selected item of the selector.

In some embodiments, the first controller 210 receives a confirmation control instruction sent by the control apparatus 100 corresponding to the display device 200, acquires display data associated with a target item currently selected by a selector in the second display screen 380 according to the confirmation control instruction, and controls the first display screen 280 to display the display data associated with the target item.

For example, referring to fig. 12a, it is assumed that three items, "program one", "program two", and "program three", are displayed in the second display screen 380 in a list manner; when the user wants to open "program two", the user can operate the selector in the second display screen 380 through the control device corresponding to the display device 200 to select "program two", and then trigger the confirmation control instruction, at this time, the first controller 210 obtains the playing resource of "program two" from the network platform, and plays on the first display screen 280.

In some embodiments, the first controller 210 is further configured to control the first display 280 to display the selector and to send a release message to the second controller 310 after receiving the confirmation control instruction; the second controller 310 is also for releasing the selector displayed in the second display screen according to the release message.

In some embodiments, in the case where the first display screen 280 displays a selector, the first controller 210 is further configured to receive a return control instruction, release the selector in the first display screen 280, and send a selector display message to the second controller 310; the second controller 310 is further configured to control the second display 280 to display the selector after receiving the selector display message sent by the first controller 210.

For better understanding of the present embodiment, referring to fig. 12a to 12d, fig. 12a to 12d are schematic diagrams of voice interaction of a display device in the embodiment of the present application.

As shown in fig. 12a, assuming that the second display screen 380 displays three items, i.e., "program one", "program two", and "program three", in a list manner in the initial state, the selector 1104 selects "program one" at the very beginning.

As shown in fig. 12b, when the user wants to open "program two", a selection control instruction for controlling the selector 1104 to move to the left and selecting "program two" may be first sent to the first controller 210 through the control device 100 corresponding to the display apparatus 200.

As shown in fig. 12c, when "program two" is selected by the selector 1104 and the confirmation control instruction is triggered, the video asset 1201 associated with "program two" is displayed on the first display screen 280. At the same time, the second display 280 releases the selector 1104 and the first display 280 displays or hides the selector.

As shown in fig. 12d, when the user wants to quit the currently playing "program two", a return control command is triggered, and at this time, the first display 280 returns to display the content before receiving the confirmation control command. At the same time, the first controller 210 releases the selector in the first display screen 280 and sends a selector display message to the second controller 310. The second controller 310 controls the second display screen 380 to display the selector 1104 after receiving the selector display message transmitted from the first controller 210.

That is, the display device 200 provided in the embodiment of the present application is provided with the second display screen and the second controller that controls the second display screen, in addition to the first display screen and the first controller that controls the first display screen, when the display device performs voice interaction, the voice interaction process can be displayed through the second display screen, the first display interface can be only used for displaying a result of the voice interaction, and therefore, the influence of the voice interaction process on the normally played content in the first display screen can be avoided.

Based on the content described in the foregoing embodiment, referring to fig. 13, fig. 13 is a first flowchart illustrating a voice interaction method of a display device according to an embodiment of the present application. After the second controller 310 controls the second display screen 380 to display the voice input interface according to the voice wake-up instruction, the method includes:

and S1301, determining whether voice is input within a preset time interval, if so, continuing to execute the step S1302, and otherwise, ending the current operation.

In a possible implementation manner, after the second controller 310 controls the second display screen 380 to display the voice input interface according to the voice wake-up instruction, the voice collecting apparatus enters a voice collecting state, if the first controller 210 does not receive the voice information collected by the voice collecting apparatus within a preset time interval (e.g., 5 seconds), it indicates that there is a misoperation currently, the first controller 210 may send a return instruction to the second controller 310, and the second controller 310 controls the second display screen 380 to return to the standby interface from the voice input interface after receiving the return instruction.
