Detailed Description

In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in 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 obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art without any inventive work based on the embodiments in the present application shall fall within the scope of protection of the present application.

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 a 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 realize 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 the 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 description of the respective concepts is only for the purpose of facilitating understanding of the contents of the present application, and does not represent a limitation to the scope of the present application.

As shown in fig. 9, the user interface includes a first diagram display area 2011 and a second diagram display area 2021. The first diagram display area 2011 and the second diagram display area 2021 have substantially the same function, and only the first diagram display area 2011 is described in an important manner below. Illustratively, the first view display area 2011 includes, among other things, layouts of 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.

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.

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.

The "item" is displayed in a view display area of the user interface in the display device 200 to represent a visual object of 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 series, 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, 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 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 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 tangible or intangible to be recognized by a user, such as a form such as a 3D distortion of an item, and may also change the identification of a border line, 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 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 various types of item layouts of the view display area. In some embodiments, the layout is modified and adjusted, including displaying or not displaying the view partitions or the content of the items in the view partitions 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 processing, and display or output the received output signal in audio or vibration form.

In some embodiments, a user may input a user command on a Graphical User Interface (GUI) displayed on the display 200, and the user input interface receives the user input command through the Graphical User Interface (GUI). Alternatively, the user may input a 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.

In order to improve the viewing experience of a user during the power-on start-up process of the display device, the present application provides a display device, as shown in fig. 10, which includes a first controller 200, a second controller 400, a first display 100 and a second display 300. Wherein the first display is at least communicatively coupled to receive control of the first controller and the second display is at least communicatively coupled to receive control of the second controller.

In some embodiments, the first display may also be connected to the second controller, and the second display may also be connected to the first controller.

In the embodiment shown in fig. 11, the first controller and the second controller can communicate with each other through a network interface (Net), a Serial interface (Serial), and a CEC.

Referring to fig. 11, a first operating system is installed on the first controller, and the first operating system at least includes a first kernel layer, a first framework layer, and various services and processes, such as an inter-process communication service (RPC) and a first target process for executing playing of the boot animation; and a second operating system is installed on the second controller, and the second operating system at least comprises a second kernel layer, a second framework layer and various services and processes, such as an interprocess communication service (RPC) and a first target process for executing and playing the boot animation.

In the embodiment shown in fig. 11, RPC communication services are respectively configured in the first operating system and the second operating system, and are respectively used for realizing communication with the second operating system/the first operating system. It can be understood that, because the RPC communication service cannot communicate with the CEC through the network interface (Net) before the boot of the operating system is completed, the RPC communication service on the first operating system or the second operating system communicates with the CEC through the Serial interface (Serial) during the boot process of the display device.

In the android system, after the display device is powered on and started, the display device can be completely started only after the inner core layer is started and the init process is completed. Taking the smart television as an example, the user needs to wait at least 20 to 50 seconds or even longer from the startup of the smart television to the playing of the TV live signal, which brings negative experience to the user.

In order to solve the problem, in the display device provided in the embodiment of the application, in the boot process, the first controller plays the first boot animation by using the first display, and the second controller plays the second boot animation by using the second display, so as to improve user experience. The first boot animation and the second boot animation can refer to the same boot animation file or different boot-up engine animations; that is, the first display and the second display may play the same boot animation or may play different boot animations, which is not limited in the present application.

FIG. 12 illustrates a flow of a display device first controller controlling a first display to play a first power-on animation, as shown in FIG. 12, the first controller configured to perform the method steps shown in FIG. 12, the first display configured to present the first power-on animation.

Step 110, detecting whether a power-on command is received.

Step 120, when a boot instruction is received, a first boot animation is obtained in response to the received boot instruction.

Step 130, playing a first boot animation on the first display.

The power-on instruction is an instruction generated by a user directly touching a power-on key on the display device or a power-on key on a display device control apparatus (such as a remote controller) to instruct to turn on the display device.

After a first controller of the display device is powered on, a first kernel layer of a first operating system is started first, and after the first kernel layer is started, a first process is initialized through the first kernel layer, namely an init process is executed, wherein the first process comprises one or more processes initialized by the init process.

The first process comprises a first target process, and the first target process is used for acquiring the first boot animation and controlling the acquired first boot animation to be played on the first display.

When the first target process is operated, the first target process can execute to acquire the first boot animation, and the first display is controlled to play the first boot animation.

In addition, when the first kernel layer is started, the first controller lights the first display screen to obtain a startup static image (startup LOGO) and controls the startup static image to be displayed on the first display before the first startup static image is displayed.

FIG. 13 illustrates a flow of the second controller of the display device playing a second power-on animation on a second display, as shown in FIG. 13, the second controller configured to perform the method steps shown in FIG. 13, the second display configured to present the second power-on animation.

Step 210, detecting whether a power-on command is received.

Step 220, when the boot instruction is received, a second boot animation is obtained.

Step 230, playing a second boot animation on the second display.

In some embodiments, the boot instruction is received by the first controller and forwarded to the second controller.

In other embodiments, the second controller may receive the power-on command directly.

In some embodiments, the second display is connected to the first controller through a General-purpose input/output (GPIO) interface, and the first controller lights up a screen of the second display through the read/write GPIO interface.

After a second controller of the display device is powered on, a second kernel layer of a second operating system is started first, and after the second kernel layer is started, a second process is initialized through the second kernel layer, namely an init process is executed, wherein the second process comprises one or more processes initialized by the init process.

The second process comprises a second target process, and the second target process is used for acquiring the second boot animation and controlling the acquired second boot animation to be played on the second display.

When the second target process is operated, the second starting-up animation can be obtained through the execution of the second target process, and the second display is controlled to play the second starting-up animation.

In the above embodiment, although the first operating system and the second operating system may both be android systems, and the processes of starting and playing the boot animation of the two systems are basically the same, due to the difference between software and hardware, the start timing sequence and the start speed of the two systems are necessarily different.

For example, the first display with a larger size is used as a main display for displaying television programs, user interfaces of various applications, and the like, and the first operating system is slower in starting speed; and the second display with smaller size is used as an auxiliary display for displaying date, weather, voice input content and the like, and the second operating system is started faster than the first operating system.

The inconsistency of the starting time sequence and the starting speed can cause inconsistency of the starting time of the first display playing the first startup animation and the starting time of the second display playing the second startup animation, so that the starting picture time of the first display and the starting picture time of the second display watched by a user are inconsistent, and user experience is influenced.

In addition, in some embodiments, since the first controller needs to control the playing of the boot LOGO before the first boot animation is played, and the second controller does not need to play the boot LOGO, the time of the first boot animation played by the first display is more advanced than the time of the second boot animation played by the second display.

In order to ensure that the first display and the second display start to play the boot animation when the display device is powered on, in another embodiment of the present application, the first controller is communicatively connected with the second controller, the first display may be connected with at least the first controller, the second display may be connected with at least the second controller, the first display is configured to present the first boot animation, the second display is configured to present the second boot animation, and the method steps of the first controller and the second controller are configured as shown in fig. 14.

Referring to fig. 14, the first controller is configured to perform the steps of:

in step 310, it is detected whether a power-on command is received.

In step 320, when the boot instruction is received, a first boot animation is obtained in response to the received boot instruction.

Step 330, playing the first boot animation on the first display, and sending a playing instruction to the second controller when the first boot animation starts to be played on the first display.

In concrete implementation, the first display responds to a starting instruction, the first kernel layer is started, after the first kernel layer is started, an initialization (init) process is executed through the first kernel layer, the initialized first process comprises a first target process, the running first target process executes to obtain first starting animation, and the first starting animation is controlled to be played on the first display.

When the first starting-up animation is controlled to be played on the first display, a playing instruction is sent to the second controller to indicate the second controller to control the second starting-up animation to be played on the second display, and therefore the time of starting playing the starting-up animation of the first display and the time of starting playing the starting-up animation of the second display are consistent.

In still other embodiments, the first display is further configured to present a power-on still image. Correspondingly, before controlling the first boot animation to be played on the first display, the first controller is further configured to light up a screen of the first display when the first kernel layer is started; and acquiring a startup static image, and playing the startup static image on the first display to realize that the startup dynamic image is played before the first startup animation.

In some embodiments, the second display screen is controlled to be illuminated by the first controller. Specifically, the second display and the first controller are connected through a GPIO interface, and before the sending of the play command to the second controller, the first controller is further configured to: and lighting up the second display screen through the GPIO interface.

With continued reference to fig. 14, the second controller is configured to perform the steps of:

in step 410, it is detected whether a power-on command is received.

In step 420, when the power-on command is received, a second power-on animation is obtained in response to the received power-on command.

Step 430, detecting whether a play instruction sent by the first controller is received.

Step 440, when receiving the playing command sent by the first controller, playing the second boot animation on the second display.

In specific implementation, the second display starts the second kernel layer in response to the start-up instruction, after the second kernel layer is started, an initialization (init) process is executed through the second kernel layer, the initialized second process comprises a second target process, a second start-up animation is obtained by running the second target process, and after the second start-up animation is obtained, the second target process is controlled to pause running until a play instruction sent by the first controller is received. And when a playing instruction sent by the first controller is received, controlling the second target process to continuously run so as to play the second boot animation on the second display through the second target process.

In this embodiment, since the second operating system is started at a higher speed, after the second operating system starts the second target process, the black screen state is maintained until the first controller lights up the second target process by reading and writing the GPIO interface, and when a play instruction sent by the first controller is received (i.e., when the first display starts playing the first boot animation), the second boot animation is played again.

As can be seen from the foregoing embodiments, in the display device provided in the present application, the first controller sends the play instruction to the second controller when starting playing the first boot animation, and the second controller starts playing the second boot animation when receiving the play instruction. The step of sending the playing instruction to the second controller by the first controller and the step of starting playing the first boot animation are executed simultaneously, and the time consumed for receiving and processing the playing instruction by the second controller is short enough to be ignored, so that the purpose of starting playing the boot animation by the first controller and the second controller simultaneously can be realized, and a user can experience the effect of synchronously playing the boot animation by the first display and the second display.

The step of sending the playing instruction to the second controller by the first controller and the step of starting playing the first boot animation are executed simultaneously, which means that the first controller executes the two steps simultaneously or the time difference between the two steps is executed is short enough.
