The layered architecture divides the software into several layers, each layer having a clear role and division of labor. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into four layers, an application layer, an application framework layer, an Android runtime (Android runtime) and system library, and a kernel layer from top to bottom.

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 audio data and video data of a user in the video call process, and can also call a camera and a microphone of nearby available equipment through near-field capabilities such as Bluetooth or WiFi to acquire a video picture shot by the nearby available equipment.

The application framework layer provides an Application Programming Interface (API) and a programming framework for the application program of the application layer. The application framework layer includes a number of predefined functions.

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

The window manager is used for managing window programs. The window manager can obtain the size of the display screen, judge whether a status bar exists, lock the screen, touch the screen, drag the screen, intercept the screen and the like.

The content provider is used to store and retrieve data and make it accessible to applications. The data may include video, images, audio, calls made and received, browsing history and bookmarks, phone books, 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, the display interface including the short message notification icon may include a view for displaying text and a view for displaying pictures.

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

The notification manager enables the application to display notification information in the status bar, can be used to convey notification-type messages, can disappear automatically after a short dwell, and does not require user interaction. Such as a notification manager used to notify download completion, message alerts, etc. The notification manager may also be a notification that appears in the form of a chart or scroll bar text at the top status bar of the system, 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, text information is prompted in the status bar, a prompt tone is given, the terminal device vibrates, an indicator light flickers, and the like.

The Android runtime comprises a core library and a virtual machine. The Android runtime is responsible for scheduling and managing an Android system.

The core library comprises 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. And executing java files of the application program layer and the application program framework layer into a binary file by the virtual machine. The virtual machine is used for performing the functions of object life cycle management, stack management, thread management, safety and exception management, garbage collection and the like.

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

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

The media library supports a variety of commonly used audio, video format playback and recording, and still image files, among others. 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 following describes the workflow of the terminal device software and hardware by way of example in conjunction with the scene of terminal device interface switching.

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

For example, the first user may switch the display areas of the one-way video picture shot by the mobile phone a, the one-way video picture shot by the mobile phone B, and the one-way video picture shot by the smart screen, for example, the first user may switch the video picture of the small window of the area 2 to be displayed in full screen in the area 1 by touching the small window of the area 2 by two times, and switch the video picture displayed in full screen in the area 1 to be displayed in the small window of the area 2, and a specific triggering manner is not specifically limited. The embodiment of the application does not specifically limit the area in which one path of video picture shot by the mobile phone A, one path of video picture shot by the mobile phone B or one path of video picture shot by the intelligent screen is displayed.

In the embodiment of the present application, the size and the position of the region 3 are not particularly limited. The size of the region 3 may be the same as that of the region 2 or may be different from that of the region 2.

For example, the video call interface of the mobile phone a may also be an interface as shown in fig. 5B, the video pictures are all displayed in the form of independent small windows, the display areas of the video pictures are area 4, area 5 and area 6, and there is no cross coverage area between area 4, area 5 and area 6. For example, the area 4 may display one video picture taken by the mobile phone a, the area 5 may display one video picture taken by the mobile phone B, and the area 6 may display one video picture taken by the smart screen.

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

In the embodiment of the present application, the size and the position of the region 4, the region 5, and the region 6 are not particularly limited. The size of the

regions

4, 5, and 6 may be the same or different.

In another possible implementation, the mobile phone a may control whether the microphone of the smart screen is turned on, as shown in fig. 6, in the video call interface of the mobile phone a, a "small speaker" button 601 may be set in a display area of a picture taken by the smart screen in the area 6, and the first user may control a switch of the microphone of the smart screen.

For example, after the first user selects a 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, a yes button 701 and a no button 702, where the yes button 701 is used to indicate that the video call is allowed to enter, the no button 702 is used to indicate that the video call is not allowed to enter, and a third user can allow 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 acquiescently agrees to 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, when the mobile phone a sends a video call request to the smart screen each time, after the smart screen receives the video call request sent by the mobile phone a, a prompt interface as shown in fig. 7 is displayed on the display screen of the smart screen, where the prompt interface includes prompt information for prompting whether to enter a video call, where the prompt interface further includes a yes button 701 and a no button 702, and a third user can approve the video call request sent by the mobile phone a by clicking the yes button 701 to display the video call interface, or continue to display an interface of an application running in the smart screen.

In another possible implementation, when the application running in the smart screen is a preset application and/or the service running in the smart screen is a preset service, a prompt interface as shown in fig. 7 is displayed on the display screen of the smart screen, where the prompt interface includes prompt information for prompting whether to enter a video call, a "yes" button 701 and a "no" button 702, and a third user can approve the video call request sent by the mobile phone a by clicking the "yes" button 701.

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

In addition, when the application running in the smart screen is not the preset application and/or the service running in the smart screen is not the preset service, the smart screen agrees with the video call request sent by the mobile phone A by default and displays a video call interface, or continues to display the interface of the application running in the smart screen. Exemplarily, when the smart screen is added to the video call between the mobile phone a and the mobile phone B, the camera of the smart screen is turned on, for example, the camera of the smart screen can be a lifting type.

In one possible implementation, the microphone of the smart screen is determined to be turned on, and one path of video picture shot by the mobile phone A, one path of video picture shot by the mobile phone B and one path of 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 smart screen, the area 7 can be an area displayed as a full screen, the areas 8 and 9 can be areas displayed as independent small windows, and no cross coverage area exists between the areas 8 and 9.

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

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

In the embodiment of the present application, the size and the position of the regions 8 and 9 are not particularly limited. The size of the regions 8 and 9 may be the same or different.

In the video call interface of the smart screen, the area 10, the area 11 and the area 12 can be 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 one video picture taken by the smart screen, the area 11 may display one video picture taken by the mobile phone B, and the area 12 may display one video picture taken by the mobile phone a. For example, in a display interface of the smart screen, a third user may switch a display area of a video picture taken by the mobile phone a, a display area of a video picture taken by the mobile phone B, and a display area of a video picture taken by the smart screen, for example, the third user drags the video picture displayed in the area 10 to the area 12 by using a mouse, the video picture displayed in the area 10 may be moved to the area 12 for display, and the video picture displayed in the area 12 may be moved to the area 10 for display, and a specific triggering manner is not specifically limited. The embodiment of the application does not specifically limit in which area the video pictures shot by the mobile phone A, the mobile phone B or the smart screen are displayed.

In the embodiment of the present application, the size and the position of the region 10, the region 11, and the region 12 are not particularly limited. The size 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 can exit the video call by clicking the "hang up" button 801.

In another possible implementation, the microphone of the smart screen is determined to be turned on, and because the mobile phone a and the smart screen are located at a short distance, the video call interface of the smart screen can display one path of video pictures shot by the mobile phone B and one path of video pictures shot by the smart screen, and does not display one path of video pictures shot by the mobile phone a. 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 one video picture taken by the smart screen, and the area 14 may display one video picture taken by the mobile phone B. In the display interface of the smart screen, a third user can switch the display area of one path of video image shot by the mobile phone B and the display area of one path of video image shot by the smart screen, and the specific triggering mode is not specifically limited. 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 the position of the region 14 are not particularly limited. The size 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 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 one video picture taken by the smart screen, and the area 16 may display one video picture taken by the mobile phone B. In the display interface of the smart screen, a third user can switch the display area of one path of video image shot by the mobile phone B and the display area of one path of video image shot by the smart screen, and the specific triggering mode is not specifically limited. The embodiment of the application does not specifically limit which area the video picture of the smart screen or the mobile phone B is displayed in.

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

In 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 the video call is accessed, and continue to display 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 tv series, and after the smart screen accesses the video call, the smart screen does not display the video call interface and continues playing the tv series.

For example, the mobile phone A can control whether a microphone of the smart screen is started, and when the microphone of the smart screen is started, the mobile phone A can call a 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 wisdom screen was not opened, cell-phone A can call the camera of wisdom screen, and the video information of the wisdom screen that the collection obtained 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 not occupied, the intelligent screen collects audio information.

For example, in the process of video call between the mobile phone a and the mobile phone B, after the mobile phone a calls the smart screen, a video picture taken by the mobile phone a, a video picture taken by the mobile phone B, and a video picture taken 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 still plays the drama, as shown in the interface of fig. 10. The embodiment of the application does not specifically limit the picture played on the smart screen.

For example, after the video call is accessed to the smart screen, a video call interface is not displayed, the mobile phone a and the mobile phone B can acquire a video picture shot by a camera of the smart screen, in order to enable a third user to join in the chat between the first user and the second user in a voice chat mode, the mobile phone a can control a microphone of the smart screen to be turned on, because the third user plays sound in videos such as a tv show or a movie, the chat among the first user, the second user and the third user can be influenced, in order to prevent the sound of the videos played in the smart screen from influencing the chat among the first user, the second user and the third user, the videos such as the tv show or the movie can be paused to be played after the video call is accessed to the smart screen.

For example, in the process of video call between the mobile phone a and the mobile phone B and the smart screen, an interaction diagram of 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, a video stream and an audio stream are added into the mobile phone A, a session 1 is established between the mobile phone A and the mobile phone B after the mobile phone A is added with the stream, and video conversation can be carried out between the mobile phone A and the mobile phone B.

For example, after the session 1 is established between the mobile phone a and the mobile phone B, in one possible implementation, the smart screen sends 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, 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 camera and the microphone of the smart screen are called by the mobile phone A, 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 a local area network and/or a Bluetooth near field sensing capability, 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, a session 2 is established between the mobile phone A and the mobile phone B after one path of video stream and one path of audio stream are added, and video call connection is established between 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 the mobile phone a according to the relationship between the mobile phone a and the smart screen logged in the social application by using the same account, the mobile phone a receives the video information from the server, 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.

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

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