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 voice receiving device and the remote controller are connected to the first controller 210, the external command recognition module 2907 of the first controller 210 may include a voice recognition module 2907-2, where a voice database is stored in the voice recognition module 2907-2, and when the voice receiving device receives an external voice command or receives a command from the outside, the voice receiving device and the like perform a corresponding relationship with the command in the voice database to perform command control on the display device. Similarly, the control device 100 such as a remote controller is connected to the first controller 210, and the key instruction recognition module 2907-3 performs instruction interaction with the control device 100.

A block diagram of the configuration of the software system in the display device 200 according to an exemplary embodiment is illustrated in fig. 7.

For the first controller 210, as shown in FIG. 7, an operating system 2911, including executing operating software for processing various underlying system services and for performing hardware-related tasks, acts as a medium for completing data processing between application programs and hardware components.

In some embodiments, portions of the operating system kernel may contain a series of software to manage display device hardware resources and to serve other programs or software code.

In other embodiments, portions of the operating system kernel may contain one or more device drivers, which may be a set of software code in the operating system that helps operate or control the devices or hardware associated with the display device. The driver may contain code to operate video, audio and/or other multimedia components. Examples include a display screen, camera, flash, wiFi, and audio drivers.

Wherein, accessibility module 2911-1 is configured to modify or access an application program to realize accessibility of the application program and operability of display content thereof.

The communication module 2911-2 is used for connecting with other peripheral devices via related communication interfaces and communication networks.

User interface module 2911-3 is configured to provide an object for displaying a user interface for access by each application program, so as to implement user operability.

Control applications 2911-4 are used to control process management, including runtime applications, and the like.

The event delivery system 2914 may be implemented within the operating system 2911 or in the application 2912. In some embodiments, one aspect is implemented within the operating system 2911, while the application 2912 is implemented to monitor various user input events, and to refer to a process program that implements one or more sets of predefined operations in response to recognition results of various events or sub-events, based on the various events.

The event monitoring module 2914-1 is configured to monitor a user input interface to input an event or a sub-event.

The event recognition module 2914-2 is configured to input definitions of various events to various user input interfaces, recognize various events or sub-events, and transmit them to a process for executing one or more corresponding sets of processes.

The event or sub-event refers to an input detected by one or more sensors in the display device 200, and an input of an external control device (such as the control apparatus 100). Such as: various sub-events are input through voice, gesture input sub-events of gesture recognition, sub-events of remote control key instruction input of a control device and the like. By way of example, one or more sub-events in the remote control may include a variety of forms including, but not limited to, one or a combination of key press up/down/left/right/, ok key, key press, etc. And operations of non-physical keys, such as movement, holding, releasing, etc.

The interface layout management module 2913 directly or indirectly receives the user input events or sub-events from the event transmission system 2914, and is used for updating the layout of the user interface, including but not limited to the positions of the controls or sub-controls in the interface, and various execution operations related to the interface layout, such as the size or position of the container, the level, and the like.

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 view display area 2011 and a view second view display area 2021. The function implementation of the first view display area 2011 and the second view display area 2021 is substantially the same, and only the first view 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.

Fig. 10-12 schematically illustrate interactions with a user by a user interface in a display device 200 according to an exemplary embodiment.

As shown in fig. 10 to 11, a video picture, which may be an image content of a movie, a television series, a video clip, or a video picture in an application, or the like, is displayed in the first display screen (specifically, the first view display area 2011). Meanwhile, the controller receives the incoming call request, and the controller displays an incoming call reminder screen on the second display screen (specifically, the second view display area 2021) in response to the incoming call request. The incoming call reminder screen includes a tab for indicating a request to answer an incoming call and a tab for rejecting the request to answer the incoming call.

After the controller displays the incoming call reminding screen on the second display screen, the incoming call reminding screen can be executed according to any one of the following two alternative modes.

In a first alternative, the controller displays a chat screen on the first display screen in response to a user-entered tab for making an incoming call request. Further, the controller may also display a widget video call screen on the second display, or on a target area of the first display, in response to a widget video call instruction from the user.

The tab of the incoming call request input by the user may also be referred to as an indication of the incoming call request input by the user.

In a second alternative manner, the controller responds to a tab input by a user and used for switching on an incoming call request, and controls the second display screen to present a chat screen. Further, the controller may also control the chat screen to switch from the second display screen to the first display screen in response to a user selection of the chat screen.

In the two modes, the incoming call connection request may refer to, for example, receiving a video incoming call, and the chat screen may refer to, for example, a video call screen.

It should be noted that in the embodiment of the present application, the number of the controllers may be one or more. When the controller is one, the controller receives an incoming call request when the first display screen displays the video picture, and displays an incoming call reminding picture on the second display screen. When the controllers are multiple, the first display screen displays the video picture through the cooperative interaction among the controllers, and the second display screen displays the incoming call reminding picture. In one embodiment, the controller may include a first controller for receiving an incoming call request and sending an incoming call indication to a second controller when the first display screen displays a video screen, and a second controller for receiving the incoming call indication and displaying an incoming call reminder screen on the second display screen. The following embodiments of the present application are each described by taking the example that the controller includes the first controller and the second controller, but this should not be construed as limiting the present application.
