Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The terms first, second and the like in the description, in the claims and in the drawings, 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 audio and video synchronization processing of a display device having a dual-system and dual-display structure, that is, a display device having a first controller (first hardware system), a second controller (second hardware system), a first display screen, and a second display screen, and first, the structure, function, implementation, and other aspects of the display device having a dual-system hardware structure will be described in detail below.

For convenience of use, various external device interfaces are usually provided on the display device, so as to connect different peripheral devices or cables to realize corresponding functions. When the high-definition camera is connected to the interface of the display device, if the hardware system of the display device does not have the hardware interface of the high-pixel camera for receiving the source code, the data received by the camera cannot be presented on the display screen of the display device.

Also, due to the hardware structure, the hardware system of the conventional display device only supports one path of hard decoding resource, and usually only supports video decoding with a resolution of 4K at maximum, so when video chat while watching the network television is to be implemented, in order not to reduce the definition of the network video picture, it is necessary to decode the network video using the hard decoding resource (typically, GPU in the hardware system), and in this case, only the video chat picture can be processed in such a way that the video is soft decoded by a general processor (e.g. CPU) in the hardware system.

The soft decoding is adopted to process the video chat pictures, so that the data processing load of the CPU is greatly increased, and when the data processing load of the CPU is too heavy, the problems of picture blocking or unsmooth can occur. In some embodiments, due to the data processing capability of the CPU, when the video chat frame is processed by soft decoding of the CPU, multiple video calls cannot be realized, and when a user wants to perform video chat with multiple other users at the same time in the same chat scene, access is blocked.

Based on the above-mentioned aspects, to overcome the above-mentioned drawbacks, the present application discloses a dual hardware system architecture to implement multiple video chat data (at least one local video).

The concepts related to the present application will be described with reference to the accompanying drawings. It should be noted that the following descriptions of the concepts are only for making the content of the present application easier to understand, and do not represent a limitation on the protection scope of the present application.

The assembly may be connected to the electronic device generally 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 a general remote control device with a touch screen user interface.

The term "gesture" as used in embodiments of the present application refers to a user behavior that is used to express an intended idea, action, purpose, and/or result by a change in hand or motion of a hand, etc.

The term "hardware system" as used in the various embodiments of the present application may refer to a physical component comprising mechanical, optical, electrical, magnetic devices such as integrated circuits (Integrated Circuit, ICs), printed circuit boards (Printed circuit board, PCBs) with computing, control, storage, input and output functions. In various embodiments of the present application, the hardware system may also be generally referred to as a motherboard (or a chip).

A schematic diagram of an operation scenario between a display device and a control apparatus according to an embodiment is exemplarily shown in fig. 1. As shown in fig. 1, a user may operate the display apparatus 200 by controlling the device 100.

The control device 100 may be a remote controller 100A, which may communicate with the display device 200 through infrared protocol communication, bluetooth protocol communication, zigBee protocol communication, or other short-range communication, and is used to control the display device 200 through wireless or other wired modes. The user may control the display device 200 by inputting user instructions through keys, voice input, control panel input, etc. on the remote controller 100A. Such as: the user can input corresponding control instructions through volume up-down keys, channel control keys, up/down/left/right movement keys, voice input keys, menu keys, on-off keys, etc. on the remote controller 100A to realize the functions of the control display device 200.

The control apparatus 100 may also be an intelligent 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 (LAN, local Area Network), a wide area network (WAN, wide Area Network), a wireless local area network (WLAN, wireless Local Area Network), or other networks, and control 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 running on a 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.

By way of example, both the mobile terminal 100B and the display device 200 may be provided with software applications, so that connection communication between the two may be implemented through a network communication protocol, thereby achieving the purpose of one-to-one control operation and data communication. Such as: the mobile terminal 100B and the display device 200 can be made to establish a control instruction protocol, the remote control keyboard is synchronized to the mobile terminal 100B, and the functions of controlling the display device 200 are realized by controlling the user interface on the mobile terminal 100B; the audio/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 device 200 may also be in data communication with the server 300 through a variety of communication means. In various embodiments of the present application, the display device 200 may be permitted to make 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 device 200.

By way of example, the display device 200 receives software program updates by sending and receiving information, and electronic program guide (EPG, electronic Program Guide) interactions, or accesses a remotely stored digital media library. The servers 300 may be one group, may be multiple groups, and may be one or more types of servers. Other web service content such as video on demand and advertising services are provided through the server 300.

The display device 200 comprises a first display screen 201 and a second display screen 202, wherein the first display screen 201 and the second display screen 202 are mutually independent, and a dual hardware control system is adopted between the first display screen 201 and the second display screen 202.

Wherein the first display 201 and the second display 202 may be used to display different display screens. For example, the first display 201 may be used for displaying a conventional television program, and the second display 202 may be used for displaying auxiliary information such as a notification message, a voice assistant, etc.

In some embodiments, the content displayed on the first display 201 and the content displayed on the second display 202 may be independent of each other and not affect each other. For example, when the first display 201 plays a television program, the second display 202 may display information such as time, weather, air temperature, a reminder message, etc. that is unrelated to the television program.

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

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

In addition, the first display 201 displays the multi-party interactive screen while displaying the conventional television program screen, and the multi-party interactive screen does not obstruct the conventional television program screen. The display modes of the traditional television program picture and the multiparty interaction picture are not limited in the application. For example, the present application may set the positions and sizes of the conventional television program picture and the multiparty interactive picture according to the priorities of the conventional television program picture and the multiparty interactive picture.

Taking the example that the priority of the traditional television program picture is higher than that of the multiparty interaction picture, the area of the traditional television program picture is larger than that of the multiparty interaction picture, and the multiparty interaction picture can be positioned at one side of the traditional television program picture or suspended at one corner of the multiparty interaction picture.

The display device 200, in one aspect, may be a liquid crystal display, OLED (Organic Light Emitting Diode) display, projection display device; in another aspect, the display device may be a smart television or a display system of a display and a set-top box. The particular display device type, size, resolution, etc. are not limited, and those skilled in the art will appreciate that the display device 200 may be subject to some changes in performance and configuration as desired.

The display device 200 may additionally provide an intelligent network television function of a computer support function in addition to the broadcast receiving television function. Examples include web tv, smart tv, internet Protocol Tv (IPTV), etc. In some embodiments, the display device may not have broadcast receiving television functionality.

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

As a connection manner in some embodiments, the camera is connected with the rear shell of the display device through the connection plate, and is fixedly installed in the middle of the upper side of the rear shell of the display device, and as a mountable manner, the camera can be fixedly installed at any position of the rear shell of the display device, so that the image acquisition area of the camera is not blocked by the rear shell, for example, the display orientation of the image acquisition area and the display device is the same.

As another connection mode in some embodiments, the camera is connected with the rear shell of the display device in a liftable manner through a connection plate or other conceivable connector, and a lifting motor is installed on the connector, so that when the user wants to use the camera or has an application program to use the camera, the camera is lifted out of the display device, and when the user does not need to use the camera, the camera can be embedded behind the rear shell, so that the camera is protected from being damaged and privacy security of the user is protected.

As an embodiment, the camera adopted in the application can be 1600 ten thousand pixels, so as to achieve the purpose of ultra-high definition display. In practical 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 in different application scenes of the display device can be fused in a plurality of different modes, so that the function which cannot be realized by the traditional display device is achieved.

For example, 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 a background picture over which a window of video chat is displayed. The function is visual and can be called as 'chat while watching'.

In some embodiments, in a "watch-while-chat" scenario, at least one video chat is conducted across terminals while live video or network video is being viewed.

In another example, a user may conduct a video chat with at least one other user while entering the educational application study. For example, students may be able to achieve remote interaction with teachers while learning content in educational applications. The function is visual and can be called as 'learning while boring'.

In another example, a user may conduct a video chat with a player entering a game while playing a card game. For example, a player may enable remote interaction with other players when entering a gaming application to participate in a game. The function is visual and can be called 'play while watching'.

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

In some embodiments, in somatosensory games (such as ball games, boxing games, running games, dancing games, etc.), human body gestures and actions are obtained through a camera, limb detection and tracking, detection of human body skeleton key point data, and then fusion with animation in the games is carried out, so that the games of scenes such as sports, dancing, etc. are realized.

In another example, a user may interact with at least one other user in a karaoke application, video and voice. The function is visual and can be called 'watch and sing'. In some embodiments, when at least one user enters the application in a chat scene, a plurality of users can jointly complete recording of a song.

In another example, the user may open the camera locally to take pictures and video, and the function may be referred to as "looking at the mirror".

In other examples, more functions may be added or the above functions may be reduced. The function of the display device is not particularly limited in this application.

Since the operating system 3911 of the first controller 310 is similar to the operating system 2911 of the first controller 210, the relevant portions are referred to the operating system 2911, and will not be described herein.

As shown in fig. 8, the application layer of the display device contains various applications that may be executed on the display device 200.

The application layer 2912 of the first controller 210 may include, but is not limited to, one or more applications such as: video on demand applications, application centers, gaming applications, etc. 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, etc. It should be noted that, what application programs are included on the second controller 310 and the first controller 210 are determined according to the operating system and other designs, and specific limitation and division of the application programs included on the second controller 310 and the first controller 210 are not required in the present application.

Live television applications can provide live television through different signal sources. For example, a live television application may provide television signals using inputs from cable television, radio broadcast, 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.

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

The media center application may provide various applications for playing multimedia content. For example, a media center may be a different service than live television or video on demand, and a user may access various images or audio through a media center application.

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

Since the second controller 310 and the first controller 210 may have separate operating systems installed therein, there are two independent but interrelated subsystems in the display device 200. For example, the second controller 310 and the first controller 210 may be independently provided with Android (Android) and various APP, which may each implement a certain function, and make the second controller 310 and the first controller 210 cooperatively implement a certain function.

A schematic diagram of a user interface in the display device 200 according to an exemplary embodiment is illustrated in fig. 9. As shown in fig. 9, the user interface includes a view first diagram display area 2011 and a second diagram display area 2021. The function implementation of the first drawing display area 2011 and the second drawing display area 2021 is substantially the same, and only the first drawing display area 2011 will be described with emphasis. By way of example, wherein the first view display area 2011 includes a layout of one or more different items. And a selector for indicating that the item is selected is also included in the user interface, and the position of the selector can be moved by user input to change the selection of a different item.

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 on-screen size or duty cycle, or that the items in the view display 201 are scalable in on-screen size or duty cycle.

"item" refers to a visual object displayed in a view display area of a user interface in the display device 200 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.

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

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

The "selector" is used to indicate that any item therein has been selected, such as a cursor or an object of focus. Positioning the selection information input according to the icon or menu position touched by the user in the display device 200 may cause movement of the display focus object 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 location is achieved or identified by drawing a thick line through the item edge. In other embodiments, the focus form is not limited to examples, and may be a form in which a cursor or the like is tangible or intangible to a user, such as a form in which a 3D deformation of an item is possible, and may also change the mark of a border line, size, color, transparency, outline, and/or font of a text or image of the focused item.

The event transmission system 2914, which may monitor user input for each predefined event or sub-event, 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 a user interface state (including a position and/or a size of a view partition, an item, a focus, or a cursor object, a change process, etc.), and according to the event or the sub-event, modify a layout of a size and a position, a hierarchy, etc. of a view display area, and/or adjust or modify a size or/and a layout of a position, a number, a type, a content, etc. of a layout of various items in the view display area. In some embodiments, modifying and adjusting the layout includes displaying or not displaying item content in each view partition or view partition 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. Illustratively, the control device (e.g., mobile terminal or remote control) may send input signals such as power switch signals, channel selection signals, volume adjustment signals, etc., input by the user to the user input interface, which may then be forwarded to the controller; alternatively, the control device may receive an output signal such as audio, video, or data, which is output from the user input interface via the controller, and display the received output signal or output the received output signal in the form of audio or vibration.

In some embodiments, a user may input a user command through 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 recognizes the sound or gesture through the sensor to receive the user input command.

A "user interface" is a media interface for interaction and exchange of information between an application or operating system and a user, which enables conversion between an internal form of information and a user-acceptable form. A commonly used presentation form of a user interface is a Graphical User Interface (GUI), which refers to a user interface graphically displayed in connection with computer operations. It may be an interface element such as an icon, a window, a control, etc. displayed in a 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 embodiments, in one possible implementation, the display device 200 further comprises a voice acquisition means.

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

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

In addition, the first display screen 280 is used for displaying service contents provided by a display content provider, such as displaying television programs, videos, games, etc.; the second display 380 is used to display content associated with user-based voice input, such as a reminder message, push message, time, weather, chat message, etc.

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

In this embodiment, the first controller 210 is configured to receive a voice wake-up instruction, and send the voice wake-up instruction to the second controller 310; the second controller 310 is configured to control the second display 380 to display a voice input interface according to the voice wake instruction; after the second display 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 identify the first voice information.

Optionally, after the first controller 210 obtains 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 searched according to the voice recognition result and sent to the first controller 210.

Optionally, after performing the voice recognition on the first voice information, the server 300 may also send a voice recognition result to the first controller 210, where 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 380 to display the voice recognition result.

It will be appreciated that in another possible embodiment, after the first controller 210 obtains the first voice information, the first voice information may be identified using the self-configured voice recognition module 2907-2.

Optionally, after the first controller 210 performs voice recognition on the first voice information by using the self-configured voice recognition module 2907-2, the voice recognition result may be directly sent to the second controller 310, and the second controller 310 controls the second display 380 to display the voice recognition result.

In a possible implementation, after the second display 380 displays the voice input interface, the microphone array corresponding to the display device 200 may be turned on to collect the first voice information sent by the user, and then the collected first voice information is transmitted to the first controller 210.

In another possible implementation manner, after the second display 380 displays the voice input interface, if the first controller detects the acquisition command triggered by the control device 100, the first controller may acquire the first voice information sent by the user through the microphone 141 on the control device 100, and at this time, the microphone array corresponding to the display device 200 may be in a closed state, so as to avoid that the microphone in the display device also acquires the voice information, thereby causing confusion. For example, when the user wants to input voice information through the microphone 141 on the control device 100, the user may continuously press the voice input key on the control device 100 and then send voice to the microphone 141 on the control device 100, and after the voice is finished, release the voice input key, where the control device 100 transmits the first voice information collected during the pressing of the voice input key to the first controller 210.

Optionally, the display device 200 may be provided with a far-field pickup module (not shown in the figure) that can collect the voice of the user remotely, without the user pressing the microphone 141 on the control apparatus 100 to pick up the sound.

Further, after the first voice information is identified, the target display data requested by the first voice information can be obtained according to the identification result and sent to the second controller 310, where the second controller 310 is configured to control the second display 380 to display the target display data.

Alternatively, the first controller 210 may transmit the voice recognition result to the server 300, and the server 300 searches for target display data related to the voice recognition result according to the voice recognition result.

It may be understood that in the embodiment of the present invention, the voice acquisition device may also be connected to the second controller 310, and the acquired voice information may be sent to the second controller 310, and the second controller 310 performs relevant processing on the voice information, and the specific processing manner may refer to the processing manner of the first controller 210, which is not described herein again.

Optionally, when the user needs to perform voice interaction with the display device 200, a voice wake-up instruction may be sent to the display device 200 through a preset wake-up mode.

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 device 100 corresponding to the display device 200, parse the received key signal, and when the received key signal is triggered and generated by a voice interaction key preset in the control device 100, the first controller 210 may confirm that a voice wake-up instruction is received.

In another possible embodiment, the user may send a preset wake-up keyword, such as "hi, curet," etc., to the voice capture device of the display apparatus 200 to send a voice wake-up instruction to the display apparatus 200. The first controller 210 may be configured to receive the voice information collected by the voice collecting device, identify the voice information, and when determining that the identification 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 can be understood that, in the embodiment of the present invention, the second controller 310 may also be configured to receive the key signal sent by the control device 100 corresponding to the display device 200, parse 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 device 100. In addition, the second controller 310 may be further configured to receive the voice information collected by the voice collecting device, identify the voice information, and confirm that the voice wake-up instruction is received when it is determined that the identification result of the voice information includes a preset wake-up keyword.

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

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

When the user needs to perform voice interaction with the display device 200, a voice wake-up instruction can be sent to the display device 200 through a preset wake-up mode. For example, in one possible implementation, the user may speak a preset wake-up keyword, such as "hi, small poly", etc., through the voice capturing device of the display apparatus 200; at this time, the voice capturing device of the display apparatus 200 sends the captured voice information to the first controller 210, the first controller 210 identifies the received voice information, if the identification 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.

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

When the second display 380 is switched from the standby interface 1101 to the voice input interface 1102, the voice capturing device begins to capture voice information input by the user, and sends the captured voice information to the first controller 210. For example, in one possible implementation, a user may speak "how do today weather? "; 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 information, the first controller 210 recognizes the voice information 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 on the voice input interface 1102, "how is the weather today? ", as shown in fig. 11 c.

Meanwhile, the first controller 210 acquires the display data related to the voice information and sends the display data to the second controller 310, and the second controller 310 controls the second display 380 to display the target display data. For example, in one possible implementation, the first controller 210 would be "how do today's weather? The "voice information is sent to the server 300, the server 300 searches the weather condition information of the place where the display device 200 is located, and feeds back the weather condition information to the first controller 210, after receiving the weather condition information, the first controller 210 sends the received weather condition information to the second controller 310, and the second controller 310 controls the second display screen 380 to display the weather condition information on the interactive display interface 1103, for example, displaying" 26 ℃ cloudy air quality is good ", and the like, see fig. 11d.

Optionally, during the above-mentioned voice interaction, the first display screen 280 may be used to play video images, game images, and the like, and may also be in a screen-off state. Here, the off-screen state may be a state including at least that the first display screen is not lit. I.e., the entire course of the voice interaction is displayed only on the second display 380 without affecting the content displayed on the first display 280.

In addition to the first display screen 280 and the first controller 210 controlling the first display screen 280, the display device 200 provided in the embodiment of the present invention is further provided with the second display screen 380 and the second controller 310 controlling the second display screen 380, and 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 content normally played in the first display screen 280 can be avoided.

Based on the description of the foregoing embodiments, in another possible embodiment, referring to fig. 12, fig. 12 is a schematic diagram showing the functional configurations of the display devices of the first controller 210 and the second controller 310 in the embodiment of the present invention.

The first controller 210 and the second controller 310 are configured to:

The first controller 210 receives the voice wake-up instruction and transmits the voice wake-up instruction to the second controller 310.

The second controller 310 controls the second display 380 to display a voice input interface according to the voice wakeup instruction.

After the second display 380 displays the voice input interface, the first controller 210 receives the first voice information collected by the voice collecting device, recognizes the first voice information, and transmits the recognition result to the second controller 310.

The second controller 310 controls the second display screen to display the recognition result.

The first controller 210 acquires the target display data requested by the first voice information, and determines whether the target display data includes first data to be displayed on the first display screen 280; when it is determined that the first data is included in the target display data, the first display screen 280 is controlled to display the first data. The second data in the target display data is sent to the second controller 310.

The second controller 310 controls the second display screen to display the second data.

That is, in this embodiment, after the first controller 210 acquires the target display data requested by the first voice information, the target display data may be classified to determine whether there is first data to be displayed on the first display screen 280 in the target display data. When it is determined that first data to be displayed on the first display screen 280 exists in the target display data, the first display screen 280 is controlled to display the first data; and simultaneously, second data except the first data in the target display data is sent to the second controller 310, and the second controller 310 controls the second display screen 380 to display the second data.

For example, when the user performs a voice conversation such as boring, inquiring about weather or time, the target display data generated in the voice interaction process may be displayed only on the second display screen 380, where there is no first data to be displayed on the first display screen 280 in the target display data; when the user performs a voice dialogue such as a movie search, the searched movie may be played on the first display screen 280, and only the searched movie name or movie list is displayed on the second display screen 380, in which case there is first data to be displayed on the first display screen 280 in the target display data.

In another possible embodiment, the first controller 210 and the second controller 310 of the display device are configured to:

the first controller 210 receives a voice wake-up instruction during the process that the first display screen 280 is in the off-screen state, and sends the voice wake-up instruction to the second controller 310.

The second controller 310 is configured to control the second display 380 to display a voice input interface according to the voice wake instruction.

The first controller 210 is further configured to: after the second display screen 380 displays the voice input interface, receiving the first voice information acquired by the voice acquisition device; acquiring target display data requested by first voice information; controlling the first display screen 280 to enter a bright screen state and displaying first data included in the target display data; and transmitting remaining data other than the first data among the target display data to the second controller 310;

The second controller 310 is further configured to control the second display 380 to display the remaining data.

Optionally, when the target display data includes the first data, the first controller 210 first determines whether the first display screen 280 is in the off-screen state; when the first display screen 280 is in the off-screen state, the first controller 210 controls the first display screen 280 to enter the bright-screen state, and then controls the first display screen 280 to display the first data.

Alternatively, when controlling the first display screen 280 to display the first data, the first controller 210 may control the first display screen 280 to generate a message popup and display the first data in the message popup.

Optionally, the first data may include at least one or more data tags (also called items in the foregoing embodiment), and the user may select to open any one of the data tags or the next display content included in any one of the data tags by manipulating the focus frame (also called selector in the foregoing embodiment). After receiving the user confirmation instruction, the first controller 210 determines whether the data tag currently selected by the focus frame in the message popup window includes the next-stage display content, if so, controls the first display screen 280 to display the next-stage display content, and if not, can display the data tag in an enlarged manner or open a link corresponding to the data tag.

For a better understanding of the present embodiment, referring to fig. 13a to 13e, fig. 13a to 13e are a second schematic voice interaction diagram of the display device according to the embodiment of the present invention.

As shown in fig. 13a, the second display 380 displays a standby interface 1101, and a pre-designed voice assistant image can be displayed in the standby interface 1101, and the voice assistant can be regarded as a voice interaction partner which is visible at any time, and in various scenes, the user is always waiting for a conversation with the user.

As shown in fig. 13b, when the user needs to perform voice interaction with the display device 200, a voice wake-up instruction may be sent to the display device 200 through a preset wake-up mode. For example, in one possible implementation, the user may speak a preset wake-up keyword, such as "hi, small poly", etc., through the voice capturing device of the display apparatus 200; at this time, the voice capturing device of the display apparatus 200 sends the captured voice information to the first controller 210, the first controller 210 identifies the received voice information, if the identification 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. 13c, after the second display 380 is switched from the standby interface 1101 to the voice input interface 1102, the voice capturing device starts capturing voice information input by the user, and sends the captured voice information to the first controller 210. For example, in one possible implementation, a user may speak "find a hot program" through the 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 information, the first controller 210 identifies the voice information and sends the identification result to the second controller 310, and the second controller 310 controls the second display 380 to display the identification result "search for the hot-broadcast program".

As shown in fig. 13d, the first controller 210 acquires the target display data related to the voice information, classifies the target display data, determines the first display data to be displayed on the first display screen 280 and the second display data to be displayed on the second display screen 380, controls the first display screen 280 to display the first display data, and simultaneously sends the second display data to the second controller 310, so that the second controller 310 controls the second display screen 380 to display the target display data.

For example, in one possible implementation, the first controller 210 sends the voice information of "searching for the hot-cast program" to the server 300, the server 300 searches for a program with the top n of the hot rank in the preset video program database, then sends the playing link of the searched program and the related introduction information to the first controller 210, and after receiving the data sent by the server, the first controller 210 controls the first display screen 280 to generate a message popup 1301, and displays the playing link of each hot-cast program searched by the server 300 and the related introduction information in the message popup 1301. And simultaneously, the number of the searched hot programs is sent to the second controller 310, and the second controller 310 controls the second display screen 380 to display the number of the searched hot programs in the interactive display interface 1103, for example, "n hot programs are searched".

Optionally, the first display 280 may display the playing links and the related introduction information of each of the hot programs found by the server 300 through different data labels 1303, and if the user wants to open any one of the hot programs, the user may select the data label corresponding to the hot program by moving the focus frame 1302 in the message popup window 1301, and then trigger the "confirm" instruction, so that the hot program 1304 may be opened in the first display 280, as shown in fig. 13 e.

In addition to the first display screen 280 and the first controller 210 controlling the first display screen 280, the display device 200 provided in the embodiment of the present invention is further provided with the second display screen 380 and the second controller 310 controlling the second display screen 380, when the display device 200 performs voice interaction, the voice interaction process can be displayed through the second display screen 380, and the first display screen 280 is only used for displaying the result of the voice interaction, thereby avoiding the influence of the voice interaction process on the content normally played in the first display screen 280.

Based on the description of the foregoing embodiment, in a possible implementation manner, after receiving the voice interaction instruction, if the first controller 210 receives an instruction for instructing to exit the voice interaction, the first controller 210 may control the first display screen 280 to return to an initial state based on the instruction, where the initial state is a state before the first controller 210 receives the voice wakeup instruction; and/or, the return instruction is sent to the second controller 310, and the second controller 310 is configured to control the second display screen 380 to return to the standby interface based on the return instruction.

For example, after controlling the second display 380 to display the voice input interface, if the first controller 210 receives the instruction, the first controller 210 sends the received instruction to the second controller 310, and the second controller 310 controls the second display 380 to switch from the voice input interface to the standby interface based on the instruction.

It will be appreciated that the display device 200 provided in the above embodiment may also be applied to other application scenarios, for example, in a possible implementation, after the second display screen 380 is switched from the standby interface 1101 to the voice input interface 1102, the user may control the display device 200 to play music through voice.

Alternatively, after the music playing application is started, the display apparatus 200 may display only song information, such as song title, artist name, album title, play progress bar, play/pause icon, volume size, etc., on the second display screen 380; the first display 280 may be in a screen-off state at this time, or may play other content, such as a presentation document, an electronic book, a game, an album, etc.

Alternatively, after the Music playing application is started, the display apparatus 200 may display song information on the second display screen 380 and simultaneously display a Music Video (MV) of a currently playing song, album art, or the like on the first display screen 280.

After receiving the voice information, the first controller 210 identifies the voice information and sends the identification result to the second controller 310, and the second controller 310 controls the second display 380 to display the identification result "play song a" on the voice input interface 1102, as shown in fig. 14 a.

After the second display 380 displays the recognition result on the voice input interface 1102, the first controller 210 obtains the playing resource and the song information related to the song a, and sends the song information to the second controller 310, where the second controller 310 controls the second display 380 to display the song information on the interactive display interface 1103 after receiving the song information, as shown in fig. 14 b. At the same time, the first controller 210 will control the speaker 272 to play song a.

In one possible implementation, the user may initiate the countdown function by voice after the second display 380 switches from the standby interface 1101 to the voice input interface 1102.

Alternatively, the display apparatus 200 may display the countdown information only on the second display screen 380 after starting the countdown function; the first display 280 may be in a blank state at this time, or other content, such as a television program, a game, a movie, etc., may be played.
