Detailed Description

To make the objects, embodiments and advantages of the present application clearer, the embodiments of the present application will be described clearly and completely with reference to the accompanying drawings in the exemplary embodiments of the present application, and it is obvious that the exemplary embodiments described are only a part of the embodiments of the present application, not all of the embodiments.

With the continuous development of display devices and related technologies, the interaction demands of users for display devices are more and more diversified. For example, when a user wants to play a display picture, a multi-channel video chat picture is presented; or when the user is in a game scene, displaying real pictures of the participants in real time; or the user can learn the current picture content in the education application program and simultaneously perform remote audio-video interaction with parents/teachers in real time, and the like. However, current display devices, especially home devices such as smart televisions, cannot realize the above-mentioned scenes because they do not have built-in cameras.

Therefore, a display device capable of presenting a conventional television picture and simultaneously presenting a multi-channel video call is urgently needed, so that a good user experience is provided for a user.

The application provides a display device, which comprises a camera and a display. As shown in fig. 1, a user may view a video program using display device 200 while at the same time engaging in an audio-video call with mobile device 100.

In some embodiments, various external device interfaces are generally disposed on the display device to facilitate connection of different devices or cables to implement corresponding functions. When a high-definition camera is connected to the interface of the display device, a hardware system of the display device needs to provide a hardware interface for receiving a high-pixel camera of the source code, so that data collected by the camera is displayed on the display.

In some embodiments, a user may use a display device to conduct an audio-video chat with another smart device while watching a web television.

When the network television is required to be watched and the video chat is carried out, the network video can be decoded by using a hard decoding resource (usually GPU in a hardware system), and a video chat picture is processed in a mode of carrying out soft decoding on the video by using a general processor (such as a CPU) in the hardware system, so that the function of carrying out the video chat while the network television is watched is not limited by a hardware structure of the display equipment, and the definition of the network video picture can be ensured.

The display device provided in the present application may be a display device having a dual-system and dual-display structure as shown in fig. 3 to 7, that is, having a first controller (a first hardware system) and a second controller (a second hardware system), or may be a display device having a non-dual system, that is, having one controller (a hardware system), or having more than two controllers (hardware systems), which is not limited in the present application.

In some embodiments, in a display device of a single system, the audio and video chat is supported while watching a network television, and the audio and video chat is also supported while watching a live television. The user can carry out audio and video chat with other users and can carry out random switching between the live television and the network television.

In some embodiments, the display device of the dual system supports processing the video chat pictures in a soft decoding manner while watching the internet protocol television and performing video chat, and can support processing multiple paths of video chat pictures at the same time, thereby avoiding a situation that access is blocked when a user wants to perform video chat with multiple other users at the same time in the same chat scene.

In some embodiments, the display device of the single system supports processing the video chat picture by adopting a soft decoding mode when the network television is watched and the video chat is carried out.

In other exemplary embodiments of the present application, the GPU/CPU processing power of some exemplary hardware systems employed by the display device is insufficient to support audio-video chat while watching a video program. When a high-definition camera is connected to an interface of a 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. And the hardware system is limited by the hardware structure, and only supports one path of hard decoding resources, and can support video decoding with 4K resolution at most, so when the network television is watched and audio and video chatting is carried out, in order not to reduce the definition of the network video picture, the GPU is needed to be used for decoding the network video, and then the CPU in the hardware system processes the video chatting picture in a mode of carrying out soft decoding on the video. And 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 unsmooth or unsmooth picture can occur. In addition, when the CPU soft decoding is adopted to process the video chat screen, a multi-path video call cannot be usually realized, and when the user wants to perform video chat with a plurality of other users in the same chat scene, the access is blocked.

In the exemplary embodiment, based on the above aspects, in order 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).

It should be noted that, the display device adopts a single system scheme, a dual system scheme or a multi-system scheme, depending on the processing division and the processing capability of the hardware system selected in the specific use, such as GPU/CPU, etc., as long as the functions of the above embodiments and the following embodiments can be implemented, which is not limited in the embodiments of the present application.

Since the functions of the operating system 3911 of the a chip are similar to those of the operating system 2911 of the N chip, reference may be made to the operating system 2911 for relevant points, and details are not repeated here.

As shown in fig. 6b, the application layer of the display device contains various applications that can be executed at the display device 200.

The N-chip application layer 2912 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. The application layer 3912 of the a-chip may include, but is not limited to, one or more applications such as: live television applications, media center applications, and the like. It should be noted that what applications are respectively contained in the a chip and the N chip is determined according to an operating system and other designs, and the present invention does not need to make specific limitations and divisions on the applications contained in the a chip and the N chip.

In the embodiment using the single hardware architecture, the single hardware architecture can combine the functions of the a chip and the N chip, and does not need to make specific limitation and division on the application program.

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 executable on the display device 200.

In some exemplary embodiments, there is a specific connection relationship between the a chip and the N chip. As shown in fig. 7, the connection, communication and power supply between the a chip (the second controller) and the N chip (the first controller) can be realized through a plurality of interfaces of different types. The interface type of the interface between the a chip and the N chip may include a General-purpose input/output (GPIO) interface, a USB interface, an HDMI interface, a UART interface, and the like. One or more of these interfaces may be used for communication or power transfer between the a-chip and the N-chip. For example, as shown in fig. 7, in the dual hardware system architecture, the N chip may be powered by an external power source (power), and the a chip may not be powered by the external power source but by the N chip.

In addition to the interface for connecting with the N chip, the a chip may further include an interface for connecting other devices or components, such as an MIPI (mobile industry processor interface) interface for connecting a Camera (Camera), a bluetooth interface, a USB interface, and the like shown in fig. 7.

Similarly, in addition to the interface for connecting with the N chip, the N chip may further include a VBY interface for connecting with a display screen TCON (Timer Control Register), and an i2S interface for connecting with a power Amplifier (AMP) and a Speaker (Speaker); and an IR/Key interface, a USB interface, a Wifi interface, a bluetooth interface, an HDMI interface, a Tuner interface, and the like.

In one embodiment, the user can also conduct video chat while watching live video. For the N-chip, it can provide a device for live tv through an HDMI2.0 external set-top box shown in fig. 7, and therefore, the N-chip is used to present live video.

The live television is directly decoded by the set top box or the radio and television, and hardware decoding resources of N chips are not occupied, so that data received by the hardware decoding camera of the N chips can be decoded when the live television is watched and video chat is carried out.

In one embodiment, the user can conduct video chat while watching the network video. In such a scenario, the network or third party application provides video-on-demand whose data requires hardware decoding resources to decode. While data received from the camera also requires hardware decoding. Therefore, if an application scene of performing video chat while watching a network video is desired, data received by the camera and the network video resource need to be decoded on two chips respectively.

When the data received by the camera is subjected to hardware decoding by the N chip, the A chip can be used for carrying out hardware decoding on the video on demand. Therefore, the A chip is used for storing and running the third-party video-on-demand application in the setting of the application program. As shown in fig. 7, the HDMI line between the a chip and the N chip is used to transmit video on demand or data for third party applications. Wherein the HDMI cable is not visible to a user. In addition, the HDMI cable is only used as an optional data transmission method, but is not limited to the HDMI cable for data transmission.

Therefore, the hardware architecture shown in fig. 7 can realize one of scenes of video chat while watching live television and video chat while watching network television, and the hardware decoding capabilities of the a chip and the N chip are not affected.

In addition, as shown in fig. 7, there may be a USB cable as a connection between the a chip and the N chip, and the USB cable is used to transmit the video data received by the camera to the N chip for hardware decoding and presentation on the display. Of course, the USB cable is only an example of a data connection method, and there may be another alternative data connection method between the a chip and the N chip. The end of the chip A is connected with a camera, and the connection between the chip A and the camera can be through an MIPI interface or a USB interface.

In the scene of performing video chat while network chat, the on-demand resource of the third-party video application in the A chip is transmitted to the N chip through the HDMI line and finally displayed on the display. The data of the camera received by the A chip is transmitted to the N chip through the USB line and is displayed on the display after being decoded.

Since the a chip and the N chip may have independent operating systems respectively installed therein, there are two independent but interrelated subsystems in the display device 200. For example, android (Android) and various APPs can be independently installed on the chip a and the chip N, so that each chip can realize a certain function, and the chip a and the chip N cooperatively realize a certain function.

Note that the display device displays a plurality of pieces of HDMI data alternatively. That is, when a user views live media playback content over an HDMI2.0 channel, other media playback content cannot be viewed over another HDMI channel. However, since the video chat contents are not connected through the HDMI channel, the video chat contents can be simultaneously displayed regardless of what type of media content is currently played.

A schematic view of a user interface in a display device 200 according to an exemplary embodiment is illustrated in fig. 8 a. As shown in fig. 8a, the user interface includes a plurality of view display areas, in some embodiments, a first view display area 201 and a second view display area 202, wherein the second view display area includes a layout of one or more different items. And a selector in the user interface indicating that the item is selected, the position of the selector being movable by user input to change the selection of a different item.

It should be noted that the multiple view display areas may present display screens of the application programs. For example, the first view display area 201 can present video chat project content, wherein the first view display area 201 includes a local view display area displaying local camera acquisition data and a remote view display area, and the second view display area 202 can present application layer project content (e.g., live video, web video, VOD presentation, application screens, etc.).

As with fig. 8b, in some embodiments, the user may close the video content of the local view display, leaving only the remote video data of the first remote view display and the content of the third view display. In this case, it is detected that the user closes the local view display area, and the camera is automatically closed. In the alternative, the motor is lowered to the initial position.

In some exemplary embodiments, there is a priority distinction for the presentation of different view display areas with respect to fig. 8a, 8b, the display priority of the view display areas being different between view display areas of different priorities. For example, the local view display area 2011 and the remote view display area 2012 have higher priority than the second view display area 202, and when the user uses the acquisition selector and the screen switching in the second view display area 202, the screen display of the first view display area 201 is not obstructed; and when the size and position of the third view display area are changed according to the selection of the user, the size and position of the first view display area 201 and the second view display area 202 are not affected.

The display screens of the same priority level can also be presented, at this time, the selector can switch between the first view display area and the second view display area, and when the size and the position of the first view display area are changed, the size and the position of the second view display area can be changed along with the change.

As one example, the first and second view display areas may present video chat project content and the second view display area may present application layer project content (e.g., live video, web video, VOD presentations, application screens, etc.).

9-10, in some embodiments, when a user opens the video chat application, a video chat interface is presented in the first view display area, and the second view display area can access the external device via HDMI2.0 to present live content; when receiving an instruction to switch to the on-demand video input by the user, the second view display area presents the on-demand content through the second controller connected by the HDMI 1.0.

As shown in fig. 9, in some embodiments, when the user opens the video chat application, the video chat interface is presented in the first view display area, and the second view display area can access the external device through HDMI2.0 to present the live media playing content; when receiving an instruction of switching to the on-demand video input by the user, the second view display area presents the on-demand media playing content through the second controller connected with the HDMI 1.0.

Specifically, the first view display area is used for presenting video chat content, and the second view display area is used for presenting media play content, where the media play content includes live media play content or on-demand media play content.

Of course, the display contents of the first view display area and the second view display area may be exchanged, that is, the first view display area may also be used to display media playing contents, and the second view display area may also be used to display video chat contents.

In some exemplary embodiments, the first view display area is displayed floating on the second view display area so as not to influence the user to watch the media playing content while the video chat is performed. The first view display area may be presented at different positions of the display according to the user's selection, e.g. the first view display area is presented in the upper right of the display.

For example, a live video program is presented on the display, for example, the live video program (e.g., a set-top box related program, a channel related program) is presented in the second view display area, a video chat request sent by the mobile terminal is received, and after the video chat request is connected, video chat content, such as a user image at the mobile terminal side, is presented in the first view display area. Meanwhile, the user image on the side of the display device can be collected through the camera and then displayed in the first view display area.

The user can still operate the media playing content interface in the video chat scene. The user can switch between the live media playing content scene and the on-demand media playing content scene at will.

The application provides a display device installs the camera, can realize chatting with the video of opposite terminal equipment, moreover, when the video chats, carries out the broadcast of live telecast, does not influence user's program and watches, can also carry out the switching of live telecast program and network television program under the video chats scene. The single scene of the traditional display equipment is overcome, the user requirements of chatting cannot be seen at the same time, the user has excellent user experience, and the use frequency and the dependence degree of the user on the display equipment are improved.

It should be noted that, whether to display the user image on the display device side in the first view display area depends on the user setting, when the user opens the camera, the image data may be collected and presented on the display, and when the user does not open the camera, the user image on the local side may not be displayed.

In some exemplary embodiments, the first view display area and the second view display area are split-screen displayed on the display on the left and right, and both may be located in the same layer or in different layers.

In other exemplary embodiments, the display modes of the first view display area and the second view display area may be switched between the two exemplary embodiments.

In some exemplary embodiments, a single hardware architecture has one controller that can support a chat-while-watching function, a view switching function, and other further functions.

In some exemplary implementations, the controller is configured to: and when a video chat request of the opposite terminal equipment is received, after the image data of the opposite terminal equipment is decoded, the image data is transmitted to a display for presentation, for example, the image data of the opposite terminal equipment is presented in a remote view display area of the first view display area.

When a user selects to open the camera, the controller is configured to decode the environment image data collected by the local camera while presenting the opposite-end video chat image, transmit the decoded environment image data to the display for presentation, and send the local video chat data to the opposite-end equipment.

In some exemplary dual hardware architectures, such as fig. 11a and 11b, the cameras are mounted on a-chips, and some applications for the cameras are stored on the a-chips and other applications for the cameras are stored on the N-chips. Therefore, the dual chips need to realize sharing of the cameras.

In some embodiments, the a-chip is connected to a camera of the physical MIPI interface. In other embodiments, the camera may also be a camera with interfaces such as USB. And setting a node of/dev/video 0 on the A chip, wherein the node is used for indicating a camera input interface on the A chip.

When the camera related application software on the A chip needs to open the camera, the node of the A chip, dev/video0, is opened. The image with determined resolution is collected, for example, the image with 1080P resolution is collected and then transmitted to the N chips for presentation through the USB connecting wire or other connecting wires.

When the camera-related application software of the N chip is used for the physical camera of the a chip, the a chip may be regarded as a camera connected through a USB interface, the a chip may be regarded as a slave device (USB camera device), and the N chip may be regarded as a master device (USB camera host).

A and N are connected through a physical USB line, so that a USB camera device can be identified to be accessed on an N chip, and a/dev/video 0 node can be generated on the N chip, but because the N capacity is limited, the A end needs to firstly carry out H264 coding or use other coding modes, then the coded data is transmitted to the N, and the N end displays an image after decoding.

When the N-chip camera related application software uses the camera, the N-chip/dev/video 0 node is opened. In order to enable the N chip/dev/video 0 node to receive data received by the camera sent by the a chip, a virtual camera, i.e., a gadget camera, needs to be implemented at the a chip end. To implement a gadget camera, a uvc-gadget (USB video class) application is implemented as a driver on the a chip.

In the UVC-gadget application program, firstly, an output node of/dev/video X needs to be virtualized in an A chip, then UVC EVENTs need to be initialized, namely, probe and comet of UVC _ device are filled, setup, data, stream and streamoff of the UVC EVENTs are registered in a driver through VIDIOC _ SUBSCRIBE _ EVENT, then the UVC EVENTs are circularly processed, data taken from A/dev/video 0 is output to/dev/video X, and then the data is transmitted to N through a USB bus.

Fig. 12 is a flowchart illustrating an exemplary method for invoking camera data acquisition by an N-chip of the camera sharing control according to the present application.

The uvc-gadget application on the A chip reads data of the MIPI camera from the node video0 of the A chip through a V4L2 interface for example, and then transmits the data to the N chip through the USB bus.

Wherein, (V4L 2 is a short for Video4Linux2 (Video for Linux two), and is a kernel driver for Video equipment in Linux, and V4L2 is an API interface for acquiring picture, video and audio data under a Linux operating system, and is mainly used for acquiring a USB camera.

For N chips, A is equivalent to a USB camera device, data of an A chip MIPI camera head can be read normally by reading/dev/video 0 of the N chips, if the N chips are limited in capacity, video data can be cut in advance according to the requirement of an N end, and the camera data which can be processed on the N can be transmitted.

In general, the V4L2 acquiring video data specifically includes: secondly, applying for a plurality of frame buffer areas for video acquisition, and mapping the frame buffer areas from a kernel space to a user space, so as to facilitate an application program to read/process video data; thirdly, queuing the applied frame buffer area in a video acquisition input queue, and starting video acquisition; fourthly, the driver starts the collection of the video data, the application program takes out the frame buffer area from the video collection output queue, after the processing is finished, the frame buffer area is put into the video collection input queue again, and continuous video data are collected in a circulating and reciprocating mode, and fifthly, the video collection is stopped.

The double hardware system chips share one camera, and in order to avoid the situation that when the N chip uses the camera, the A chip calls the camera again, the application discloses a distribution method for calling the camera.

Fig. 13 is a logic flow diagram illustrating a camera call for an N chip of camera sharing control according to an example embodiment of the present application.

In an embodiment, when no application occupies the camera currently, the camera application is opened at the N-chip end, and a flag bit is written on the a-chip in a dual-system communication manner (the attribute value sys.camera.nova _ used is recorded in the camera node currently used on N), so as to flag that the camera node Video0 is currently used by N. Such as sys.camera.nova _ used = 0. When the N chip does not use the camera, a marking position is reset at A, and the current N is marked without using any camera node, wherein sys.camera.nova _ used = -1;

similarly, when the camera application is opened on the a chip, a flag bit is written on the a chip (the attribute value is stored in the camera node currently used on N, and this flag bit is used to mark that the camera node Video0 is currently used by a, for example, sys, camera, am _ used = 0; when the release camera is closed, the flag bit is reset, and the flag indicates that the current A does not use any camera node, and sys.

FIG. 14 is a logic flow diagram illustrating a camera invocation by an A chip of the exemplary camera sharing control of the present application;

if the application on the N chip is opened and uses the camera, when the application on the A chip is opened and uses the camera, and when the application on the A chip calls a frame layer interface of the camera, a frame layer of the camera can firstly take out a value in an attribute sys.camera.nova _ used of the camera to obtain an occupied camera node usedcamerarid, and the camera is prompted to be occupied at present.

When the chip A is connected with an external camera through an external USB interface. When the camera is opened and used again by the application on the chip A and the application on the chip A calls a frame layer interface of the camera, the frame layer of the camera firstly takes out a value in the attribute sys.camera.nova _ used of the camera to obtain a camera node used Camera Id which is occupied, the IDs of the camera nodes opened by the application in the chip A are compared, and if the IDs are the same, the camera is prompted to be occupied currently; instead, the camera to which the designated camera Id is applied is allowed to be opened. If the Camera is not specified when the application A calls the Camera, the framework layer can open the rear Camera by default, the list of the whole Camera Id needs to be traversed at the moment, if the current used Camera Id is rear, the next rear Camera can be searched, and if the current used Camera Id is not found, the Camera to be opened currently is prompted to be occupied; if a new rear camera is found, the newly found rear camera is opened.
