Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying 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 present application is mainly directed to a sound and picture synchronization process of a display device having a dual-system and dual-display structure, that is, 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 structures, functions, implementation manners, 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. Further, 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, access is blocked.

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 201 and a second display 202, wherein the first display 201 and the second display 202 are independent from each other, and a dual hardware control system is adopted between the first display 201 and the second display 202.

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 screen display of conventional television programs, and the second display 202 may be used for screen display of auxiliary information such as notification type messages, voice assistants, and the like.

Alternatively, the content displayed by the first display 201 and the content displayed by the second display 202 may be independent of each other and not affected by each other. For example, when the first display 201 plays a television program, the second display 202 may display information such as time, weather, temperature, reminder messages, and the like, which are not related to the television program.

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

Optionally, part or all of the content displayed by the second display 202 may be adjusted to be displayed by the first display 201. For example, the information such as time, weather, temperature, reminder message, etc. 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 201 displays the multi-party interactive picture while displaying the 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 an optional connection mode, the camera is connected with the rear shell of the display device through the connecting plate, and is fixedly installed in the middle of the upper side of the rear shell of the display device.

As another optional connection mode, the camera is connected to the rear shell of the display device through a connection board or another conceivable connector, the camera is capable of lifting and descending, a lifting motor is installed on the connector, when a user wants to use the camera or an application program wants to use the camera, the camera is lifted out of the display device, and when the camera is not needed, the camera can be embedded into the rear shell, so that the camera is protected from being damaged, and privacy safety 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'.

Optionally, in a scene of "chat while watching", at least one video chat is performed across terminals while watching a live video or a network video.

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".

Optionally, the game scene is fused with the video picture, the portrait in the video picture is scratched and displayed in the game picture, and the user experience is improved.

Optionally, in the motion sensing game (such as ball hitting, boxing, running and dancing), the human posture and motion, limb detection and tracking and human skeleton key point data detection are obtained through the camera, and then the human posture and motion, the limb detection and tracking and the human skeleton key point data detection are fused with the animation in the game, 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". Optionally, 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.
