Fig. 2 is a block diagram illustrating a software configuration of the terminal device 100 according to the embodiment of the present application.

The layered architecture divides the software into several layers, each with distinct roles and branches. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into four layers, from top to bottom, an application layer, an application framework layer, an Zhuoyun row (Android run) and system libraries, and a kernel layer, respectively.

The application layer may include a series of application packages. As shown in fig. 2, the application package may include camera, gallery, phone, map, phone, music, settings, mailbox, video, social, etc. applications.

The social application program can acquire the audio data and the video data of the user in the video call process, and can also call the cameras and the microphones of nearby available devices through near field capability such as Bluetooth or WiFi so as to acquire video pictures shot by the nearby available devices.

The application framework layer provides an application programming interface (application programming interface, API) and programming framework for application programs of the application layer. The application framework layer includes a number of predefined functions.

As shown in FIG. 2, the application framework layer may include a window manager, a content provider, a resource manager, a view system, a notification manager, and the like.

The window manager is used for managing window programs. The window manager may obtain the display screen size, determine if there is a status bar, lock the screen, touch the screen, drag the screen, intercept the screen, etc.

The content provider is used to store and retrieve data and make such data accessible to applications. The data may include video, images, audio, calls made and received, browsing history and bookmarks, phonebooks, etc.

The view system includes visual controls, such as controls to display text, controls to display pictures, and the like. The view system may be used to build applications. The display interface may be composed of one or more views. For example, a display interface including a text message notification icon may include a view displaying text and a view displaying a picture.

The resource manager provides various resources for the application program, such as localization strings, icons, pictures, layout files, video files, and the like.

The notification manager allows the application to display notification information in a status bar, can be used to communicate notification type messages, can automatically disappear after a short dwell, and does not require user interaction. Such as notification manager is used to inform that the download is complete, message alerts, etc. The notification manager may also be a notification in the form of a chart or scroll bar text that appears on the system top status bar, such as a notification of a background running application, or a notification that appears on the screen in the form of a dialog window. For example, a text message is prompted in a status bar, a prompt tone is emitted, the terminal equipment vibrates, and an indicator light blinks.

Android runtimes include core libraries and virtual machines. Android run time is responsible for scheduling and management of the Android system.

The core library consists of two parts: one part is a function which needs to be called by java language, and the other part is a core library of android.

The application layer and the application framework layer run in a virtual machine. The virtual machine executes java files of the application program layer and the application program framework layer as binary files. The virtual machine is used for executing the functions of object life cycle management, stack management, thread management, security and exception management, garbage collection and the like.

The system library may include a plurality of functional modules. For example: surface manager (surface manager), media Libraries (Media Libraries), three-dimensional graphics processing Libraries (e.g., openGL ES), 2D graphics engines (e.g., SGL), etc.

The surface manager is used to manage the display subsystem and provides a fusion of 2D and 3D layers for multiple applications.

Media libraries support a variety of commonly used audio, video format playback and recording, still image files, and the like. The media library may support a variety of audio video encoding formats, such as: MPEG4, h.264, MP3, AAC, AMR, JPG, PNG, etc.

The three-dimensional graphic processing library is used for realizing three-dimensional graphic drawing, image rendering, synthesis, layer processing and the like.

The 2D graphics engine is a drawing engine for 2D drawing.

The kernel layer is a layer between hardware and software. The inner core layer at least comprises a display driver, a camera driver, an audio driver and a sensor driver.

The workflow of terminal equipment software and hardware is illustrated below in connection with the scenario of terminal equipment interface switching.

When a touch sensor in the terminal equipment receives touch operation, a corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the touch operation into the original input event (including information such as touch coordinates, touch strength, time stamp of the touch operation, etc.). The original input event is stored at the kernel layer. The application framework layer acquires an original input event from the kernel layer and identifies a button corresponding to the input event. Taking the touch operation as a touch click operation, taking a button corresponding to the click operation as an example of a button of a social application icon, the social application calls an interface of an application framework layer, starts the social application, and further starts a display driver by calling a kernel layer to display a functional interface of the social application.

With the development of terminal technology, the functions of the terminal equipment are more and more abundant, the terminal equipment can be configured with a camera and a video chat function, and a user can carry out video chat through the terminal equipment.

In a possible implementation, in the video call process of the first user and the second user, the first terminal of the first user may receive a video picture captured by the front camera or the rear camera of the second terminal of the second user, and the second terminal of the second user may also receive a video picture captured by the front camera or the rear camera of the first terminal of the first user. The common video call pulling is realized by using social software, and the terminal equipment only supports the video call pulled by friends in the social software in a single chat or group chat mode. For example, the first user, the second user, and the third user are friends in the social application a, and after the first user, the second user, and the third user respectively open the social application a, the first user, the second user, and the third user may pull up the video call each other, or after three people enter a chat group, pull up a group video chat of three people.

In this implementation, for the fourth user who does not open the social application a or does not join the chat group, if the fourth user wants to join the video call of the first user, the second user, and/or the third user in the social application a, or if the first user, the second user, and/or the third user wants to know the fourth user based on the terminal device of the fourth user in the video chat of the social application a, the situation cannot be implemented.

For example, when the first user and the second user are in the same residence during video chat, but the first user and the fourth user are in different rooms, if the second user wants to acquire a video picture including the fourth user, the first user cannot pull up the terminal device of the fourth user, cannot obtain the video picture of the fourth user based on the terminal device of the fourth user, and the first user needs to move the first terminal to the room where the fourth user is located for shooting. Therefore, in the method, the video call of the terminal equipment has limitation, and the user experience is affected.

In view of this, an embodiment of the present application provides a video call system, including a first terminal, a second terminal, and a third terminal; the first terminal is configured to establish a video call based on the first application and the second terminal, and display a first video call interface, wherein the first video call interface displays first video information collected by a camera of the first terminal and second video information collected by a camera of the second terminal; the second terminal is configured to establish a video call based on the first application and the first terminal, and display a second video call interface, wherein the second video call interface displays first video information and second video information; the first terminal is further configured to receive a first operation, the first operation is configured to select a third terminal, and the third terminal and the first terminal are logged in the same account in the first application; the third terminal and the first terminal are positioned in the same local area network and/or positioned in the same Bluetooth coverage area; and responding to the first operation, displaying a third video call interface, wherein the third video call interface displays first video information, second video information and third video information, and the third video information is video information collected by a camera of a third terminal; the second terminal is further configured to display a fourth video call interface, and the fourth video call interface displays the first video information, the second video information and the third video information. In the video call system, the first terminal can acquire video pictures in other areas by calling the cameras and the microphones of nearby available equipment, so that the nearby available equipment can be conveniently added into the video call, the limitation of user addition and video pictures in the video call is reduced, and the user experience is improved.

In this embodiment of the present application, the terminal device of the first user may be a first terminal, the terminal device of the second user may be a second terminal, the available nearby device may be a third terminal, and the example is illustrated by taking the first terminal as a mobile phone a, the second terminal as a mobile phone B, and the third terminal as a smart screen, which does not constitute a limitation of the embodiment of the present application.

The display positions of the second user avatar and the avatar are not specifically limited in the embodiment of the present application, and the display icons of the "answer" button 301 and the "reject" button 302 are not specifically limited in the embodiment of the present application.

Illustratively, the first user enters the video call interface as shown at b in fig. 3 by clicking the "answer" button 301. As shown in B in fig. 3, the video shot by the mobile phone a is located in the area 1, and the video shot by the mobile phone B is located in the area 2.

In this embodiment of the present application, in the video call interface of the mobile phone a, the area 1 may be an area displayed as a full screen, and the area 2 may be an area displayed as a small window. The position and size of the area 2 are not particularly limited in the embodiment of the present application. The first user can switch the display areas of the pictures shot by the mobile phone a and the mobile phone B according to the need, for example, by clicking the small window of the area 2, switch the video picture of the small window of the area 2 to the full-screen display of the area 1, switch the video picture of the full-screen display of the area 1 to the small window of the area 2, and the specific switching triggering mode is not limited specifically. The display area of the picture shot by the mobile phone a and the display area of the picture shot by the mobile phone B are not particularly limited.

By way of example, in a video call interface as shown in b in fig. 3, a "multiple camera" button 303, a "hang-up" button 304, and a "switch voice" button 305 may be included.

Wherein the first user may retrieve the video pictures taken by the nearby available devices by clicking the "invoke device" button 308 to invoke the cameras of the nearby available devices. The implementation of the specific calling device will be described in detail in the following embodiments, which are not described herein.

The technical scheme of the present application and the technical scheme of the present application are described in detail below with specific examples. The following embodiments may be implemented independently or combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

The embodiment of the application provides a video call system, and the following describes the video call system related to the embodiment of the application.

The embodiment of the application provides a video call system, in which a video picture shot by an intelligent screen can be acquired, as shown in fig. 4.

For example, the area 4 may display a video shot by the mobile phone a, the area 5 may display a video shot by the mobile phone B, and the area 6 may display a video shot by the smart screen.

For example, the first user may switch the display areas of one video picture shot by the mobile phone a, one video picture shot by the mobile phone B, and one video picture shot by the smart screen, for example, the first user drags the video picture displayed in the area 4 to the area 6 by touching the mobile phone a, then the video picture displayed in the area 4 may be moved to the area 6 to be displayed, and the video picture displayed in the area 6 may be moved to the area 4 to be displayed, and the specific triggering mode is not limited specifically. The embodiment of the application does not specifically limit the area in which one video picture shot by the mobile phone A, one video picture shot by the mobile phone B or one video picture shot by the intelligent screen is displayed.

In the embodiment of the present application, the sizes and positions of the areas 4, 5, and 6 are not particularly limited. The dimensions of the region 4, the region 5 and the region 6 may be the same or different.

In another possible implementation, as shown in fig. 6, in the video call interface of the mobile phone a, a "small horn" button 601 may be set in the display area of the picture shot by the smart screen in the area 6, so that the first user may control the on/off of the microphone of the smart screen.

Illustratively, after the first user selects the smart screen in the device list 401, the handset a may send a video call request to the smart screen.

In a possible implementation, if the mobile phone a sends a video call request to the smart screen for the first time, after receiving the video call request sent by the mobile phone a, the smart screen displays a prompt interface as shown in fig. 7 on a display screen of the smart screen, where the prompt interface includes prompt information for prompting whether to enter the video call, "yes" button 701 and "no" button 702, where the "yes" button 701 is used to indicate that the mobile phone a is authorized to enter the video call, the "no" button 702 is used to indicate that the mobile phone a is not authorized to enter the video call, and a third user may agree to the video call request sent by the mobile phone a by clicking the "yes" button 701. If the mobile phone A does not send the video call request to the smart screen for the first time, the smart screen defaults to agree with the video call request sent by the mobile phone A, and displays a video call interface, or continues to display an interface of an application running in the smart screen.

In another possible implementation, each time the mobile phone a sends a video call request to the smart screen, the smart screen displays a prompt interface as shown in fig. 7 on the display screen of the smart screen after receiving the video call request sent by the mobile phone a, where the prompt interface includes prompt information for prompting whether to enter a video call, and a yes button 701 and a no button 702 are included in the prompt interface, and the third user may agree to the video call request sent by the mobile phone a by clicking the yes button 701, display the video call interface, or continue to display the interface of the application running in the smart screen.

It should be noted that, the preset application includes an application for playing video, and the preset service includes a video playing service. For example, the preset application may be a game application, a video application, or a video conference application, and the preset service may be a play service of a television or a movie, and the preset service does not include an advertisement play service, where the advertisement generally has an advertisement identifier, and whether the preset service is the advertisement play service may be determined by the advertisement identifier.

In addition, when the application running in the intelligent screen is not a preset application and/or the service running in the intelligent screen is not a preset service, the intelligent screen defaults to the video call request sent by the mobile phone A, and displays a video call interface, or continues to display the interface of the application running in the intelligent screen. When the smart screen is added to the video call between the mobile phone a and the mobile phone B, for example, the camera of the smart screen may be up-down, which is not limited in the embodiment of the present application.

In one possible implementation, the microphone of the smart screen is turned on by default, and a video picture shot by the mobile phone a, a video picture shot by the mobile phone B and a video picture shot by the smart screen are displayed in the video call interface of the smart screen. After joining the video call, the display interface of the smart screen may be as shown in fig. 8A and 8B.

Illustratively, in the interface shown in fig. 8A, the video call interface of the smart screen may be divided into a region 7, a region 8, and a region 9. In the video call interface of the intelligent screen, the area 7 can be an area which is displayed as a full screen, the area 8 and the area 9 can be areas which are displayed as independent small windows, and no cross coverage area exists between the area 8 and the area 9.

For example, the area 7 may display a video shot by the smart screen, the area 8 may display a video shot by the mobile phone B, and the area 9 may display a video shot by the mobile phone a.

In the display interface of the smart screen, the third user may switch the display areas of one video picture shot by the mobile phone a, one video picture shot by the mobile phone B, and one video picture shot by the smart screen, for example, the third user may switch the video picture displayed by the small window of the area 8 to be displayed in the area 7 in a full screen manner through double clicking the small window of the area 8 with a mouse, and switch the video picture displayed in the area 7 in the full screen manner to be displayed in the small window of the area 8, which is not limited in a specific triggering manner. The embodiment of the application does not specifically limit in which area the video picture shot by the mobile phone a, the mobile phone B or the smart screen is displayed.

In the embodiment of the present application, the sizes and positions of the areas 8 and 9 are not particularly limited. The dimensions of the region 8 and the region 9 may be the same or different.

Illustratively, in the interface shown in fig. 8B, the video call interface of the smart screen may be divided into a region 10, a region 11, and a region 12. In the video call interface of the smart screen, the area 10, the area 11 and the area 12 can be all displayed as independent small windows, and no cross coverage area exists among the area 10, the area 11 and the area 12.

For example, the area 10 may display a video shot by the smart screen, the area 11 may display a video shot by the mobile phone B, and the area 12 may display a video shot by the mobile phone a. In the display interface of the smart screen, for example, the third user may switch the display areas of the video frame shot by the mobile phone a, the video frame shot by the mobile phone B, and the video frame shot by the smart screen, for example, the third user drags the video frame displayed in the area 10 to the area 12 through the mouse, so that the video frame displayed in the area 10 may be moved to be displayed in the area 12, and the video frame displayed in the area 12 may be moved to be displayed in the area 10, and the specific triggering mode is not limited specifically. The embodiment of the application does not specifically limit in which area the video picture shot by the mobile phone a, the mobile phone B or the smart screen is displayed.

In the embodiment of the present application, the sizes and positions of the areas 10, 11, and 12 are not particularly limited. The dimensions of the region 10, the region 11 and the region 12 may be the same or different.

Of course, in the video call interface of the smart screen, the third user may exit the video call by clicking the "hang-up" button 801.

In another possible implementation, the microphone of the smart screen is turned on by default, and because the distance between the mobile phone a and the smart screen is relatively short, one video picture shot by the mobile phone B and one video picture shot by the smart screen can be displayed in the video call interface of the smart screen, and one video picture shot by the mobile phone a is not displayed. After joining the video call, the display interface of the smart screen is shown in fig. 9A and 9B.

Illustratively, in the interface shown in fig. 9A, the video call interface of the smart screen may be divided into a region 13 and a region 14. In the video call interface of the smart screen, the area 13 may be an area displayed as a full screen, and the area 14 may be an area displayed as an independent small window.

For example, the area 13 may display a video shot by the smart screen, and the area 14 may display a video shot by the mobile phone B. In the display interface of the smart screen, the third user can switch the display area of one video picture shot by the mobile phone B and one video picture shot by the smart screen, and the specific triggering mode is not limited specifically. The embodiment of the application does not specifically limit in which area the video picture shot by the smart screen or the mobile phone B is displayed.

In the embodiment of the present application, the size and position of the region 14 are not particularly limited. The dimensions of the regions 14 may be the same or different.

Illustratively, in the interface shown in fig. 9B, the video call interface of the smart screen may be divided into a region 15 and a region 16. In the video call interface of the intelligent screen, the area 15 and the area 16 can be used as the areas displayed by independent small windows, and no cross coverage area exists between the area 15 and the area 16.

For example, the area 15 may display a video shot by the smart screen, and the area 16 may display a video shot by the mobile phone B. In the display interface of the smart screen, the third user can switch the display area of one video picture shot by the mobile phone B and one video picture shot by the smart screen, and the specific triggering mode is not limited specifically. The embodiment of the present application does not specifically limit in which area the video picture of the smart screen or the mobile phone B is displayed.

In the embodiment of the present application, the sizes and positions of the regions 15 and 16 are not particularly limited. The dimensions of the region 15 and the region 16 may be the same or different.

In yet another possible implementation, in order not to affect the normal viewing of the smart screen by the third user, the smart screen may not display the video call interface after accessing the video call, and continue displaying the interface of the application running in the smart screen. For example, when the mobile phone a sends a video call request to the smart screen, the smart screen is playing a television play, and after the smart screen is connected to the video call, the smart screen does not display a video call interface, and continues to play the television play.

The mobile phone a can control whether the microphone of the smart screen is turned on, and when the microphone of the smart screen is turned on, the mobile phone a can call the camera and the microphone of the smart screen at the same time to acquire video information of the smart screen including voice and pictures; when the microphone of the smart screen is not started, the mobile phone A can call the camera of the smart screen to acquire video information of the smart screen including the picture. In addition, when the smart screen continues to display the interface of the application running in the smart screen, if the microphone in the smart screen is occupied, the smart screen may not collect audio information; if the microphone in the intelligent screen is unoccupied, the intelligent screen collects audio information.

For example, in the video call process of the mobile phone a and the mobile phone B, after the mobile phone a calls the smart screen, one video picture shot by the mobile phone a, one video picture shot by the mobile phone B, and one video picture shot by the smart screen are displayed in the video call interfaces of the mobile phone a and the mobile phone B, and the display picture on the display area 17 of the smart screen is still playing a television, as shown in the interface of fig. 10. The embodiment of the application does not specifically limit the picture played on the intelligent screen.

The smart screen may not display a video call interface after the smart screen is connected to the video call, the mobile phone a and the mobile phone B may acquire video pictures shot by the camera of the smart screen, so that in order to enable the third user to join in the chat between the first user and the second user in the form of voice chat, the mobile phone a may control the microphone of the smart screen to be turned on, and since the third user plays sound in videos such as a television play or a movie, the chat between the first user, the second user and the third user may be affected, and in order to not enable the sound of the video played in the smart screen to affect the chat between the first user, the second user and the third user, the playing of videos such as the television play or the movie may be paused after the smart screen is connected to the video call.

For example, in the process of making video call between the mobile phone a and the mobile phone B and the smart screen, an interaction diagram between the mobile phone a and the mobile phone B and the smart screen is shown in fig. 11. After video communication connection is established between the mobile phone A and the mobile phone B, one path of video stream and one path of audio stream are added into the mobile phone A, and after the video communication connection is established between the mobile phone A and the mobile phone B, a session 1 is established between the mobile phone A and the mobile phone B, so that video communication can be carried out between the mobile phone A and the mobile phone B.

For example, after the mobile phone a and the mobile phone B establish the session 1, in one possible implementation, the smart screen sends the video information collected by the camera of the smart screen to the mobile phone a, the mobile phone a receives the video information from the smart screen, and sends the video information collected by the camera of the mobile phone a to the mobile phone B through the session 1, and sends the video information collected by the camera of the smart screen to the mobile phone B through the session 2.

When the mobile phone A invokes the camera and the microphone of the smart screen, private communication connection is established between the mobile phone A and the smart screen through a private communication protocol, for example, the mobile phone A and the smart screen can be connected through near field sensing capability such as local area network and/or Bluetooth, another path of video stream and another path of audio stream are added into the mobile phone A through the smart screen, the video stream and the audio stream are transmitted to the mobile phone A, the mobile phone A establishes a session 2 with the mobile phone B after adding one path of video stream and one path of audio stream, and video call connection is completed among the mobile phone A, the mobile phone B and the smart screen.

In another possible implementation, the smart screen sends video information collected by the camera of the smart screen to a server (not shown), the server sends the video information to mobile phone a according to the relationship between mobile phone a and the same account in the smart screen login social application, mobile phone a receives the video information from the server, and sends video information collected by the camera of mobile phone a to mobile phone B through session 1, and sends video information collected by the camera of the smart screen to mobile phone B through session 2.

In yet another possible implementation, the smart screen sends video information collected by the camera of the smart screen to the mobile phone a and video information collected by the camera of the smart screen to the mobile phone B.

It can be understood that the mobile phone a in the embodiment of the present application may be replaced by a first terminal in any form, similarly, the mobile phone B may be replaced by a second terminal in any form, and the smart screen may be replaced by a third terminal in any form.
