detailed description

Hereinafter, embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. Although some embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments set forth herein. On the contrary, these embodiments are provided for Have a more thorough and complete understanding of this disclosure. It should be understood that the drawings and embodiments of the present disclosure are only used for exemplary purposes and are not used to limit the protection scope of the present disclosure.

It should be understood that the steps recorded in the method embodiments of the present disclosure may be executed in a different order, and/or executed in parallel. Furthermore, method implementations may include additional steps and/or omit to perform the illustrated steps. The scope of the present disclosure is not limited in this respect.

The term "including" and its variations as used herein are open-ended includes, that is, "including but not limited to". The term "based on" is "based at least in part on." The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". Related definitions of other terms will be given in the following description.

It should be noted that the concepts of “first” and “second” mentioned in the present disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order of functions performed by these devices, modules or units. Or interdependence.

It should be noted that the modifications of “a” and “a plurality of” mentioned in this disclosure are illustrative and not restrictive. Those skilled in the art should understand that unless the context clearly indicates otherwise, they should be understood as “one or Multiple".

The names of messages or information exchanged between multiple devices in the embodiments of the present disclosure are only used for illustrative purposes, and are not used to limit the scope of these messages or information.

Currently, screen projection can be realized between different terminals in a wireless local area network. For example, through Airplay, screen projection between Apple devices and a set-top box or TV with Airplay function can be realized. Use Airdrop to project Android ecological content to the corresponding screen or device. Existing mainstream operating systems, such as Windows, iOS, and Android, behave as follows when they are projected: When terminal A casts a screen to terminal B, it is limited by the system limitations of terminal B, and can only present one projected content at a time ; When terminal B is screened by terminal A, the content of terminal B cannot be called and presented to the user. However, according to different usage situations, sometimes there is a need to connect multiple terminals to the projection device. For example, when a multi-party conference call is held, if the projection content of multiple terminals can be output on the projection device at the same time, it can be This allows the user to pay attention to the screen content of multiple terminals at the same time, without having to switch the screen content on the screen projection device between each terminal, which can improve the user experience. In addition, sometimes users also have the need to operate the projection device itself while paying attention to the projection content from other terminals. If the content of the projection device itself and the projection content from other terminals are simultaneously output on the projection device, The user can operate the content of the screen projection device itself without switching between the screen projection device itself and other terminals, which is convenient for the user to operate.

The present disclosure provides a screen projection method in response to the above-mentioned actual needs. The method will be described in detail below with reference to the drawings.

FIG. 1 is a flowchart showing the projection method of the present disclosure, and FIG. 2 is a schematic block diagram showing the projection method of the present disclosure.

As shown in FIG. 1, in step 101, the screen projection device receives and decodes the screen projection source from multiple terminals via the transmission channel between each terminal and the screen projection device. Here, the screen projection source is the realization content in the terminal, which can be multimedia content including one or more of multiple elements such as text, image, and sound. The projection device has one or more of the functions of displaying text, images, and playing sounds. The display of the projection device can be, for example, a liquid crystal display, a projector, an IPTV, etc. The projection device performs the projection of the present disclosure through an operating system. The screen method is described in detail later. In addition, in the description of the present disclosure, the meaning of “output” on the screen projection device should not be limitedly interpreted as only the display of text and images, but can also be understood as including the realization of sound playback. The multiple terminals can be mobile terminals or non-mobile terminals such as mobile phones, desktop computers, notebook computers, vehicle-mounted computers, PADs, and servers. As shown in Figure 2, each of the multiple terminals (terminals A, B...) is connected to the projection device via its own transmission channel (such as a digital radio path), and transmits the projection source. Add a terminal, add a digital wireless channel, and add an independent window (independent window A, B, ...) on the projection device.

In step 102, an independent window corresponding to each terminal is established on the display of the projection device, and the projection content is displayed on the corresponding independent window according to the decoded projection source.

After performing step 102, the screencast content from multiple terminals is simultaneously screened in multiple windows on the screen projection device, thereby enabling the user to simultaneously pay attention to the status of multiple terminals and improving the efficiency of the user in obtaining information.

In addition, in the present disclosure, the window manager can also be used to determine the respective projections of multiple independent windows based on the size of the displayable area on the display of the projection device that can be used to display multiple independent windows and the number of terminals. Screen size. In this way, it is possible to avoid the situation where the projection size of the independent window is too small to make full use of the displayable area, and the situation where the independent window is too large to exceed the displayable area.

It should be noted that the window manager (Window manager) module of the Android system is used for window management. The window manager of the Android system of the related technical solution does not allow multiple Android application windows to be opened at the same time, and cannot keep every application available. The window manager of the Android system in the present disclosure has been modified to allow multiple Android application windows to be opened at the same time, and to keep each application available. The above-mentioned window manager modifications mainly include: the relevant window manager always allows only one active window, while the modified window manager allows multiple active windows; the relevant window manager limits the coordinate starting point of the window layout to the position The same position, and the modified window manager can set the coordinate starting point of the window layout in multiple different positions. For specific implementation methods, please refer to the following descriptions. However, the following descriptions in the present disclosure are only examples to illustrate their practicability, and are not limited descriptions, and other technologies can also be used to implement them.

Regarding the output (implementation) of allowing multiple active windows, the present disclosure exemplifies the following ways to implement it. When the terminal of the Android operating system creates a window, it is realized by creating an Activity component, and when the terminal creates an Activity component, the window manager is notified that it needs to display a startup window for the Activity component that is starting. In the present disclosure, multiple windows are displayed simultaneously through the following operations. When performing screen projection operations from multiple terminals, the projection device creates an Activity component in response to the reception of the projection source, and the window manager creates an independent window in response to the creation of the Activity component. When creating the first independent window, create the first Activity component based on the data decoded from the projection source and pass the display parameters of the first independent window to the first Activity component, and the window manager will use the first independent window The first independent window is created based on the display parameters, so that the created first independent window can be displayed on the screen in a windowed manner. When creating the Nth independent window, create the Nth Activity component based on the decoded data from the Nth projection source and pass the display parameters of the Nth independent window to the Nth Activity component. The window manager The display parameters of the N independent windows create the Nth independent window.

In addition, when the projection terminal detects a new window creation instruction, it usually transfers the focus label to the newly created window, that is, performs focus transfer. The detection focus label belongs to the concept of the master task and the slave task on the terminal. Among them, the window designated as the focus is the main task, and the main task can perform various operations, such as dragging and playing. The slave task can refer to a window that has been created but is not operated. At this time, since it is not designated as the focus window, the window of the slave task is usually in a suspended or frozen state. However, in the present disclosure, multiple independent windows are simultaneously activated through the following operations. In the present disclosure, when the focus of the application is switched, the independent window whose focus has been transferred is not notified, and the application state is not changed, so that the independent window continues to run. For example, the first independent window is the video window as the current focus window, and the user newly creates a chat page window as the second independent window, and the focus label is transferred to the second independent window after the second independent window is created. It is worth noting that while the second independent window obtains the focus label, the first independent window still remains in the playing state because it has not received the focus transfer notification, and will not become paused or frozen due to loss of focus. This allows multiple active windows to be allowed.

Regarding the setting of the coordinate starting point of multiple active windows, the following manners are exemplified in the present disclosure. The default method is to pass the parameters of full-screen display to the created Activity component, so that the created window is also displayed in full-screen. However, in the present disclosure, when creating the first...Nth Acitivity component, the display parameters including the starting point coordinates, window size, etc., passed into the first...Nth Acitivity component are different, so Make the multiple independent windows created by the window manager corresponding to the first...Nth Acitivity component on the projection device, the coordinates of the starting point are different, which can be displayed in different positions, and can have different Window size. More specifically, if the upper left corner of the display area of the screen is set to coordinates (0,0) by default, the starting point of the independent window is usually set to coordinates (0,0), and the window size is set to full screen display. However, in the present disclosure, the starting point coordinates in the display parameters passed into the Acitivity component are not limited to (0,0), the starting point coordinates of each independent window can be staggered with each other, and the window size is not limited to the full screen. The independent windows can adopt different window sizes from each other.

The main flow of the screen projection method of the present disclosure has been described above. In order to facilitate the understanding of the present disclosure, the following is a more specific description based on embodiments.

Example 1

FIG. 3 is a diagram for explaining an example of the screen projection method of the present disclosure. As shown in Figure 3, in the displayable area that can be used to display multiple independent windows on the display of the projection device, 6 independent windows are created at the same time, and the 6 independent windows are displayed in a tiled manner with the same size. Simultaneously project the projection sources from 6 terminals on the projection device.

Example 2

FIG. 4 is a diagram for explaining an example of the screen projection method of the present disclosure. As shown in Figure 4, similar to Embodiment 1, in the displayable area on the display of the projection device that can be used to display multiple independent windows, six independent windows are created at the same time, and the user does not view any of them from the projection device. When the window is operated, the 6 independent windows are displayed in the same size and in a tiled manner, and the projection sources from the 6 terminals are simultaneously projected on the projection device. In this embodiment 2, when the user When the screen device side operates one of the independent windows such as independent window 1 (such as mouse click, touch screen click, dragging, keyboard operation, etc.), the projection device receives the signal of the operation and confirms which independent window is for Operate, and enlarge and display the independent window 1 in response to the signal. The magnification can be the preset default magnification, or it can be defined that different operations of the user correspond to different magnifications. For example, two fingers can hold two points of an independent window on the touch screen and stretch to any magnification. The finger double-clicks the independent window on the touch screen at the same time to enlarge the independent window by 3 times and so on. At this time, the display position of the independent window 1 can also be adjusted at the same time. In Figure 4, it is illustrated that the display position of the independent window 1 is adjusted to the center of the displayable area, and the independent window 1 is displayed on the uppermost layer to ensure this The independent window 1 is visible as a whole. However, it is not limited to adjusting only to the center of the displayable area, as long as it can ensure that the entire independent window 1 is visible.

Example 3

FIG. 5 is a diagram for explaining an example of the screen projection method of the present disclosure. As shown in Figure 5, the difference from Embodiment 2 is that in Embodiment 3, when the user operates one of the independent windows, such as independent window 1, from the projection device side, the projection device receives the The operation signal confirms which independent window is the operation, and in response to the signal, the independent window 1 is enlarged and displayed, and at the same time, other independent windows are reduced and displayed. The setting of the magnification is the same as in Example 2. The reduction magnification of other independent windows preferably reduces all other independent windows to the same default small size that is preset, so that other independent windows on the display of the projection device are arranged neatly to avoid messy layout. At this time, the display position of each independent window can also be adjusted at the same time. In Figure 5, the display position of the independent window 1 is adjusted to the center of the displayable area, and the display position of other independent windows is adjusted to the displayable area. Near the edge, so as to avoid overlapping of other independent windows with the independent window 1, making the independent window 1 more recognizable.

Example 4

FIG. 6 is a diagram for explaining an example of the screen projection method of the present disclosure. As shown in Figure 6, in the displayable area that can be used to display multiple independent windows on the display of the screen projection device, 4 independent windows are created at the same time, and the 4 independent windows are displayed in a tiled manner. The projection source of the screen is simultaneously projected on the projection device. The display sizes of the four independent windows can correspond to the display sizes of the projection source on the terminal, that is, if it is a terminal with displays of different sizes, the sizes of the independent windows projected to the projection device can be different. If it is a terminal with a display of the same size, the size of the independent window projected to the projection device is usually the same. Some of the multiple terminals have the same display size or the same terminal type (for example, all mobile phones or all tablet computers). You can use this part of the terminals as preset terminals. The terminal is preset so that the projection screen sizes of the corresponding independent windows are the same. As a result, it is possible to avoid the situation that the projection sources with large original size differences are projected in the same independent window, to avoid the zoom ratio of the projection content of different terminals being too large, and to avoid the occupation of the projection sources with smaller original sizes In the case of an independent window of the same size as the original larger projection source. For example, in this embodiment 4, taking the case of simultaneous projection of a 4-inch mobile phone, a 6-inch mobile phone, a 9-inch PAD, and a 14-inch notebook computer as an example, the size of the independent window corresponding to the 14-inch notebook computer is the largest. The size of the corresponding independent window is the smallest.

Example 5

FIG. 7 is a diagram for explaining an example of the screen projection method of the present disclosure. As shown in Figure 7, in the displayable area that can be used to display multiple independent windows on the display of the screen projection device, 4 independent windows are created at the same time, and the 4 independent windows are displayed in an overlapping manner with the same size. The projection sources from 4 terminals are simultaneously projected on the projection device. One of the independent windows (independent window 1) is displayed on the top layer. In Embodiment 5, when a certain independent window is operated from the projection device side and designated to be displayed on the uppermost layer, the independent window is moved to the uppermost layer. For example, at least a part of the independent window outside the top layer (such as the title bar, etc.) is exposed. When the part of an independent window is operated by mouse click, touch screen click, dragging, keyboard operation, etc., the independent window will move to the lowest position. upper layer. In addition, the uppermost independent window can also completely cover other independent windows. At this time, the uppermost independent window can be switched through specific operations, such as long press, drag, and slide on the touch screen.

In addition, although FIG. 7 illustrates that four independent windows are displayed with the same size, it is not limited to this, and the sizes may be different as shown in FIG. 6.

Example 6

In Embodiment 6, in the case of receiving a projection source from another terminal and establishing an independent window corresponding to the projection source, an independent window corresponding to the application of the projection device is also established, and the projection device’s own The content is output on this separate window. That is, the content of the projection device itself is output in the independent window, such as displaying information such as video, picture, or text, or outputting audio information. For screen projection of other terminals, reference may be made to the above-mentioned embodiments, and other methods of projection may also be used. In this way, the information of the projection device itself can also be completely provided to the user, avoiding the situation where the independent windows corresponding to other terminals block part of the display content of the projection device itself and the content of the projection device itself cannot be completely displayed. In addition, in the sixth embodiment, the number of other terminals is not particularly limited. When the screen is projected from one terminal or from multiple terminals, the display content of the projection device itself is displayed as an independent window. In the case that the screen projection of all other terminals is cut off, it automatically responds to the cut off or responds to a manual recovery operation so that the independent window corresponding to the screen projection device itself is restored to full screen display.

Above, the screen projection method of the present disclosure has been described based on the embodiments and application examples. In addition, the present disclosure also provides a screen projection device, mobile terminal, and storage medium. These screen projection devices, mobile terminals, and storage media are described below.
