Detailed Description

For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

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 term "remote control" as used in the various embodiments of the present application refers to a component of an electronic device (such as a display device as disclosed herein) that can typically wirelessly control the electronic device over a relatively short range of distances. 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; alternatively, the display device 200 may be a smart television or a display system composed 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.
