Detailed Description

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

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.

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, a voice database is stored in the voice recognition module 2907-2, and when the voice receiving device receives an external voice command or the like, the voice receiving device and the like perform a corresponding relationship with a 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 button command recognition module 2907-3 performs command interaction with the control device 100.

Fig. 7 is a block diagram illustrating a configuration of a software system in the display device 200 according to the exemplary embodiment.

With respect to the first controller 210, as shown in FIG. 7, the operating system 2911, which includes executing operating software for handling various basic system services and for performing hardware related tasks, acts as an intermediary between applications and hardware components for performing data processing.

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

In other embodiments, portions of the operating system kernel may include one or more device drivers, which may be a set of software code in the operating system that assists in operating or controlling the devices or hardware associated with the display device. The drivers may contain code that operates the video, audio, and/or other multimedia components. Examples include a display screen, a camera, Flash, WiFi, and audio drivers.

The accessibility module 2911-1 is configured to modify or access the application program to achieve accessibility and operability of the application program for displaying content.

A communication module 2911-2 for connection to other peripherals via associated communication interfaces and a communication network.

The user interface module 2911-3 is configured to provide an object for displaying a user interface, so that each application program can access the object, and user operability can be achieved.

Control applications 2911-4 for controlling process management, including runtime applications and the like.

The event transmission system 2914 may be implemented within the operating system 2911 or within the application 2912. In some embodiments, an aspect is implemented within the operating system 2911, while implemented in the application 2912, for listening for various user input events, and will implement one or more sets of predefined operations in response to various events referring to the recognition of various types of events or sub-events.

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

The event identification module 2914-2 is used to input various event definitions for various user input interfaces, identify various events or sub-events, and transmit them to the process for executing one or more sets of their corresponding handlers.

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 (e.g., the control apparatus 100). Such as: the method comprises the following steps of inputting various sub-events through voice, inputting a gesture sub-event through gesture recognition, inputting a remote control key command of a control device and the like. Illustratively, the one or more sub-events in the remote control include a variety of forms including, but not limited to, one or a combination of key presses up/down/left/right/, ok keys, key presses, and the like. And non-physical key operations such as move, hold, release, etc.

The interface layout management module 2913, directly or indirectly receiving the input events or sub-events from the event transmission system 2914, monitors the input events or sub-events, and updates the layout of the user interface, including but not limited to the position of each control or sub-control in the interface, and the size, position, and level of the container, which are related to the layout of the interface.

Since the operating system 3911 of the controller 310 and the operating system 2911 of the first controller 210 have similar functions, reference may be made to the operating system 2911 for relevant points, and details are not repeated here.

As shown in fig. 8, the application layer of the display device contains various applications that can be executed at 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: a video-on-demand application, an application center, a game application, 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 view display area 2011 and a second view display area 2021. The first view display area 2011 and the second view display area 2021 have substantially the same function, and only the first view display area 2011 is described in an important manner below. Illustratively, among other things, the first view display 2011 includes layouts for one or more different items. And a selector indicating that the item is selected is also included in the user interface, and a position of the selector is movable by a user input to change a selection of a different item.

In some embodiments, the first view display area 2011 is a scalable view display. "scalable" may mean that the first view display area 2011 is scalable in size or proportion on the screen, or that the items in the view display 201 are scalable in size or proportion on the screen.

"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 icons, thumbnails, video clips, and the like. For example: the items may represent movies, image content or video clips of a television show, audio content of music, applications, or other user access content history information.

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

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

A "selector" is used to indicate where any item has been selected, such as a cursor or a focus object. Positioning the selection information input according to an icon or menu position touched by the user in the display 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.
