Detailed Description
Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While certain embodiments of the present disclosure are shown in the drawings, it is to be understood that the present disclosure may be embodied in various forms and should not be construed as limited to the embodiments set forth herein, but rather are provided for a more thorough and complete understanding of the present disclosure.

It should be understood that the various steps recited in the method embodiments of the present disclosure may be performed in a different order, and/or performed in parallel. Moreover, method embodiments may include additional steps and/or omit performing the illustrated steps. The scope of the present disclosure is not limited in this respect.
The term "include" and variations thereof as used herein are open-ended, i.e., "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".

It is noted that references to "a", "an", and "the" modifications in this disclosure are intended to be illustrative rather than limiting, and that those skilled in the art will recognize that "one or more" may be used unless the context clearly dictates otherwise.
The names of messages or information exchanged between devices in the embodiments of the present disclosure are for illustrative purposes only, and are not intended to limit the scope of the messages or information.
Currently, screen projection can be implemented between different terminals in a wireless local area network. For example, through the Airplay, screen projection between the apple equipment and a set-top box or a television with the Airplay function can be realized. The Android ecological content is projected onto a corresponding screen or device using Airdrop. The existing mainstream operating systems, such as Windows, iOS, and Android, are represented as follows when being projected: when the terminal A casts a screen to the terminal B, the screen is limited by the system limit of the terminal B, and only one content of the casted screen can be presented at a time; and when the terminal B is projected by the terminal A, the content of the terminal B can not be called and presented to the user. However, according to different use situations, there is a need to connect a plurality of terminals to the screen projection device, for example, when a multi-party teleconference is performed, if the screen projection contents of the plurality of terminals can be simultaneously implemented on the screen projection device, a user can pay attention to the screen projection contents of the plurality of terminals at the same time, the screen projection contents on the screen projection device do not need to be switched among the terminals, and the user experience can be improved. In addition, sometimes the user has a need to operate the screen projecting device while paying attention to the screen projecting content from other terminals, and if the content of the screen projecting device and the screen projecting content from other terminals are simultaneously implemented on the screen projecting device, the user can operate the content of the screen projecting device without switching between the screen projecting device and other terminals, so that the user can conveniently operate the screen projecting device.
In view of the above-mentioned practical needs, the present disclosure provides a screen projection method, which is described in detail below with reference to the accompanying drawings.
Fig. 1 is a flowchart illustrating a screen projecting method of the present disclosure, and fig. 2 is a schematic block diagram illustrating the screen projecting method of the present disclosure.
As shown in fig. 1, in step 101, a screen projection device receives screen projection sources from a plurality of terminals via a transmission channel between each terminal and the screen projection device and decodes the screen projection sources. Here, the screen-casting source is implementation content in the terminal, and may be multimedia content including one or more of various elements such as text, image, and sound. The screen projection device has one or more functions of displaying text, images, playing sound, etc., the display of the screen projection device may be, for example, a liquid crystal display, a projector, an IPTV, etc., the screen projection device executes the screen projection method of the present disclosure through an operating system, and the screen projection device is described in detail later. In addition, in the description of the present disclosure, the meaning of "displaying" on the screen projection apparatus should not be construed restrictively as only displaying of text and images, but may also be understood as including implementation of sound playing and the like. The plurality of terminals can be mobile terminals or non-mobile terminals such as mobile phones, desktop computers, notebook computers, vehicle-mounted computers, PADs, servers and the like. As shown in fig. 2, each of the plurality of terminals (terminal A, B … …) is connected to the screen projection device via a respective transmission channel (e.g., a digital radio path) and transmits a projection source, and each additional terminal adds a digital radio channel and adds a separate window (separate windows A, B, … …) to the screen projection device.
In step 102, on a display of the screen projection device, an independent window corresponding to each terminal is established, and screen projection content is realized on the corresponding independent window according to the decoded screen projection source.
After the step 102 is executed, the screen-projected contents from the plurality of terminals are simultaneously projected in a plurality of windows on the screen-projecting device, so that the user can focus on the states of the plurality of terminals at the same time, and the efficiency of the user for acquiring information is improved.
In addition, in the present disclosure, the window manager may be used to determine the respective screen projection sizes of the plurality of independent windows according to the size of the displayable area available for displaying the plurality of independent windows on the display of the screen projection apparatus and the number of terminals. Therefore, the situation that the projection size of the independent window is too small to fully utilize the displayable area and the situation that the independent window is too large to exceed the displayable area can be avoided.
It should be noted that a Window manager (Window manager) module of the Android system is used for managing windows. The existing window manager of some versions of the Android system does not allow multiple Android application windows to be opened simultaneously, and cannot keep each application available. The window manager of the Android system in the present disclosure is modified to allow multiple Android application windows to be opened simultaneously and to keep each application available. The modification of the window manager mainly includes: past window managers have always allowed only one active window, while modified window managers have allowed multiple active windows; the former window manager limits the coordinate starting point position of the window layout to the same position, and the modified window manager can set the coordinate starting point of the window layout at a plurality of different positions. Although the following description refers to a specific implementation, the following description in the present disclosure is only an example for illustrating the implementability thereof, and is not a limiting description, and other technologies may be used to implement the same.
Regarding the implementation allowing multiple active windows, the following manner is exemplified in the present disclosure. When the terminal of the android operating system creates the window, the terminal is realized by creating an Activity component, and when the terminal creates the Activity component, the terminal informs a window manager that a starting window needs to be displayed for the active component which is being started. In the present disclosure, a plurality of frames are simultaneously displayed by the following operations. When screen projection operation is performed from a plurality of terminals, the screen projection device creates an Activity component in response to the reception of a screen projection source, and the window manager creates an independent window in response to the creation of the Activity component. When the first independent window is created, a first Activity component is created according to data decoded by a screen projection source, display parameters of the first independent window are transmitted to the first Activity component, and the window manager creates the first independent window according to the display parameters of the first independent window, so that the created first independent window can be displayed in a window mode in a screen. When an Nth independent window is created, an Nth Activity component is created according to data obtained by decoding the Nth screen projection source, display parameters of the Nth independent window are transmitted to the Nth Activity component, and the window manager creates the Nth independent window according to the display parameters of the Nth independent window.
In addition, when the screen projection terminal detects a new window creation instruction, the focus label is usually transferred to the newly created window, that is, focus transfer is performed. The detection focus label belongs to the concept of a master task and a slave task on the terminal. Wherein, the window designated as the focus is the primary task, and the primary task can perform various operations, such as dragging, playing, and the like. A slave task may refer to a window that has been created but not operating, at which time the window of the slave task is typically in a paused or frozen state because it is not designated as a focus window. However, in the present disclosure, a plurality of independent windows are simultaneously activated by the following operations. In the present disclosure, when switching the focus of an application, the independent window to which the focus is transferred is not notified, and the state of the application 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 to which the focus tab is transferred after the second independent window is created. It should be noted that, while the second independent window obtains the focus label, the first independent window still keeps the playing state due to not receiving the notification of focus transition, and does not become a pause or freeze state due to losing focus. Thereby, enabling multiple active windows.
Regarding the setting of the coordinate start points of the plurality of active windows, the following manner is exemplified in the present disclosure. The default is to pass the parameters of the full screen display into the created Activity component so that the created window is also displayed full screen. However, in the present disclosure, in creating the first … … nth activity component, by making different display parameters including a start point coordinate, a window size, and the like, which are transmitted into the first … … nth activity component, so that a plurality of independent windows created by the window manager corresponding to the first … … nth activity component are on the screen projection apparatus, the coordinates of the start point are different, and thus may be displayed at different positions and may have different window sizes. More specifically, if the upper left corner of the display area of the screen is defaulted to the coordinates (0,0), the start point of the individual window is usually set to the coordinates (0,0) and the window size is set to full-screen display, but in the present disclosure, the start point coordinates in the display parameters passed into the activity component are not limited to (0,0), the start point coordinates of the individual windows may be staggered from each other, the window size is not limited to full-screen, and a plurality of individual windows may adopt different window sizes from each other.
The main flow of the screen projection method of the present disclosure is described above, and for the convenience of understanding the present disclosure, the following description is more specifically described based on the examples.
Example 1
Fig. 3 is a diagram for explaining an example of the screen projecting method of the present disclosure. As shown in fig. 3, in a displayable area on a display of the screen projecting device, which is available for displaying a plurality of independent windows, 6 independent windows are simultaneously established, the 6 independent windows are displayed in a tiled manner with the same size, and screen projecting sources from 6 terminals are simultaneously projected on the screen projecting device.
Example 2
Fig. 4 is a diagram for explaining an example of the screen projecting method of the present disclosure. As shown in fig. 4, similar to embodiment 1, in a displayable area on a display of a screen projection device, which is available for displaying a plurality of independent windows, 6 independent windows are simultaneously established, when a user does not operate any window from a screen projection device side, the 6 independent windows are displayed in the same size and in a tiled manner, screen projection sources from 6 terminals are simultaneously projected on the screen projection device, and in embodiment 2, when the user operates (for example, mouse click, touch screen click, drag, keyboard operation, and the like) one of the independent windows, for example, independent window 1 from the screen projection device side, the screen projection device receives a signal of the operation, confirms which independent window the operation is directed to, and displays the independent window 1 in an enlarged manner in response to the signal. The magnification ratio may be a preset default magnification ratio, or different operations of the user may be defined to correspond to different magnification ratios, for example, two fingers press two points of the independent window on the touch screen and stretch to any magnification ratio, three fingers double-click the independent window on the touch screen at the same time to magnify the independent window by 3 times, and the like. In this case, the display positions of the individual windows 1 may be adjusted at the same time, and fig. 4 illustrates that the display positions of the individual windows 1 are adjusted to the center of the displayable region, and the individual windows 1 are displayed on the uppermost layer so as to ensure that the entire individual windows 1 are visible. However, the adjustment is not limited to only the center of the displayable region, and the entire individual window 1 may be ensured to be visible.
Example 3
Fig. 5 is a diagram for explaining an example of the screen projecting method of the present disclosure. As shown in fig. 5, the difference from embodiment 2 is that in embodiment 3, when the user operates one of the independent windows, for example, independent window 1, from the screen projection apparatus side, the screen projection apparatus receives a signal of the operation, confirms which of the independent windows is the operation, and displays the independent window 1 in an enlarged manner in response to the signal, while displaying the other independent windows in a reduced manner. The magnification was set in the same manner as in example 2. The reduction ratios of the other independent windows preferably enable all the other independent windows to be reduced to the preset same default small size, so that the other independent windows on the display of the screen projection equipment are arranged in order, and the messy layout is avoided. In this case, the display positions of the individual windows may be adjusted at the same time, and fig. 5 illustrates that the display position of the individual window 1 is adjusted to the center of the displayable region, and the display positions of the other individual windows are adjusted to the vicinity of the edge of the displayable region, so that the other individual windows are prevented from overlapping the individual window 1, and the visibility of the individual window 1 is improved.
Example 4
Fig. 6 is a diagram for explaining an example of the screen projecting method of the present disclosure. As shown in fig. 6, in a displayable area on a display of the screen projecting device, which is available for displaying a plurality of independent windows, 4 independent windows are simultaneously established, the 4 independent windows are displayed in a tiled manner, and screen projecting sources from 4 terminals are simultaneously projected on the screen projecting device. The display size of the 4 independent windows corresponds to the display size of the screen projection source on the terminal, i.e. if the terminal is provided with displays of different sizes, the sizes of the independent windows projected onto the screen projection device will be different. Therefore, the condition that the screen projection source with larger original size difference is projected with the same independent window can be avoided, the condition that the screen projection content of different terminals is overlarge in scaling is avoided, and meanwhile, the condition that the screen projection source with smaller original size occupies the independent window with the same size as the screen projection source with larger original size is avoided. For example, in this embodiment 4, taking the case of simultaneously projecting 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, and the size of the independent window corresponding to the 4-inch mobile phone is the smallest.
Example 5
Fig. 7 is a diagram for explaining an example of the screen projecting method of the present disclosure. As shown in fig. 7, in a displayable area on a display of the screen projecting device, which is available for displaying a plurality of independent windows, 4 independent windows are simultaneously established, the 4 independent windows are displayed in the same size and in an overlapping manner, and screen projecting sources from 4 terminals are simultaneously projected on the screen projecting device. In which 1 independent window (independent window 1) is displayed at the uppermost layer. In example 5, when a separate window is operated from the screen projection device side and specified to be displayed on the uppermost layer, the separate window is moved to the uppermost layer. For example, at least a part (e.g., title bar) of the independent window other than the uppermost layer is exposed, and when the part of an independent window is operated by a mouse click, a touch screen click, a drag, a keyboard operation, or the like, the independent window moves to the uppermost layer. In addition, the uppermost independent window may completely cover the other independent windows, and in this case, the switching of the uppermost independent window may be realized by a specific operation, for example, a long press, a drag, a slide, or the like on the touch screen.
Although fig. 7 illustrates 4 independent windows displayed in the same size, the size is not limited to this, and may be different as shown in fig. 6.
Example 6
In embodiment 6, when receiving a screen projection source from another terminal and establishing an independent window corresponding to the screen projection source, an independent window corresponding to an application of a screen projection device itself is also established, and the content of the screen projection device itself is implemented on the independent window. The content of the screen projection device itself is output in the independent window, for example, information such as video, pictures or characters is displayed or audio information is output. For the screen projection of other terminals, the above embodiments can be referred to, and other modes can be adopted. Therefore, the information of the screen projection equipment can be completely provided for the user, and the situation that the display content of the screen projection equipment is partially shielded by independent windows corresponding to other terminals, so that the content of the screen projection equipment cannot be completely displayed is avoided. In embodiment 6, the number of other terminals is not particularly limited, and the display content of the screen projection device itself is displayed as an independent window regardless of whether the screen is projected from one terminal or from a plurality of terminals. And under the condition that the screen projection of all other terminals is cut off, automatically responding to the cut-off or responding to a manual recovery operation to recover the independent window corresponding to the screen projection equipment to full-screen display.
In the above, the screen projection method of the present disclosure is explained based on the embodiment and the application example. In addition, the present disclosure also provides a screen projection device, a mobile terminal, and a storage medium, which are described below.
The screen projection equipment is used for projecting a plurality of terminals, and comprises: the receiving module is used for receiving and decoding a screen projection source from a plurality of terminals through a transmission channel between each terminal and the screen projection equipment; and the window management module is used for establishing a respective corresponding independent window for each terminal on a display of the screen projection equipment and realizing screen projection content on the corresponding independent window according to the decoded screen projection source.
For the embodiment of the screen projection device, since it basically corresponds to the method embodiment, reference may be made to the partial description of the method embodiment for relevant points. The above described embodiments of the screen projection device are merely illustrative, wherein the modules illustrated as separate modules may or may not be separate. Some or all of the modules may be selected according to actual needs to achieve the purpose of the solution of the present embodiment.
