The method may include steps 101 to 102 described below.

Step 101, the first electronic device determines a first screen projection mode based on interface information of a display interface of the first electronic device.

The first screen projection mode is one of at least two preset screen projection modes.

It may be appreciated that in the embodiment of the present application, the display interface may be an interface displayed by the first electronic device.

Alternatively, the display interface may be an audio-video playing interface, a background interface (including at least one application identifier indicating a background running program object), a desktop, app pages, and the like. In this embodiment of the present application, the display interface may be any interface that may be displayed on the screen of the first electronic device, which is not limited in this embodiment of the present application.

Optionally, in an embodiment of the present application, the interface information includes at least one of: display content information of the interface and display parameter information of the interface. The interface information may also be other information of the interface, which is not limited in the embodiments of the present application.

It is to be understood that the display content information of the interface is information of the content displayed by the interface, and may be, for example, video content, chat content, or the like. The display parameter information of the interface may include resolution, brightness, frame rate, display ratio (full screen display, half screen display) and the like of the interface.

It may be understood that in the embodiment of the present application, the preset at least two screen-throwing modes may be a started screen-throwing mode in the first electronic device, or may be a screen-throwing mode between the first electronic device and the second electronic device, or may be another screen-throwing mode, which is not limited in the embodiment of the present application.

Optionally, the at least two screen projection modes may include a mirror screen projection mode and a push screen projection mode, and may further include other screen projection modes, which are not limited in the embodiment of the present application.

The at least two screen projection modes are a mirror screen projection mode and a push screen projection mode, and the first screen projection mode is a mirror screen projection mode or a push screen projection mode.

It can be appreciated that in the embodiment of the present application, each of the preset at least two screen modes is in an available state (or a standby state or a suspended state) or an in-use state (and the first electronic device is currently using one of the screen modes), rather than a disabled state, that is, the switch controlling each screen mode is turned on.

In the embodiment of the application, the first electronic device may determine, in real time, a currently applicable screen-casting mode according to a process operated by a foreground and an operation of a user (at least including the following two cases: 1, no screen-casting is used before and is now required to be used, 2, one screen-casting mode is used before and is now required to be switched to another screen-casting mode), and then, based on the screen-casting mode, screen-casting is performed by the second electronic device.

In the embodiment of the present application, the first electronic device may be a small-screen electronic device (an electronic device with a screen size smaller than or equal to the first threshold value), or may be a large-screen electronic device (an electronic device with a screen size larger than the first threshold value), which is not limited in the embodiment of the present application. The second electronic device may be a large-screen electronic device (an electronic device with a screen size greater than the first threshold value) or a small-screen electronic device (an electronic device with a screen size smaller than or equal to the first threshold value), which is not limited in the embodiments of the present application. The first threshold may be determined according to actual use requirements, which is not limited in the embodiments of the present application.

Optionally, the first electronic device may further determine the first screen projection mode based on the interface information and other information.

The above step 101 may be implemented by the following step 101a, for example.

Step 101a, the first electronic device determines a first screen projection mode based on the interface information and attribute information of the first electronic device.

It may be appreciated that in the embodiment of the present application, the attribute information may include information such as electric quantity information and temperature information of the first electronic device.

If the attribute information is the power information of the first electronic device, the first screen mode may be considered to be a screen mode with lower power consumption when the power indicated by the power information of the first electronic device is lower than a first threshold (determined according to actual use requirements, which is not limited in the embodiments of the present application); when the electric quantity indicated by the electric quantity information of the first electronic equipment is higher than the first threshold value, the first screen-throwing mode can be considered to be a screen-throwing mode with more power consumption.

For example, if the attribute information is temperature information of the first electronic device, when the temperature indicated by the temperature information of the first electronic device is lower than a second threshold (determined according to actual use requirements, which is not limited in the embodiments of the present application), the first screen-throwing mode may be considered to be a screen-throwing mode that generates more heat; when the temperature indicated by the temperature information of the first electronic device is higher than the second threshold value, the first screen-throwing mode can be considered to be a screen-throwing mode with less heat generation.

In the embodiment of the application, the screen projection mode suitable for the first electronic device can be better determined by combining the interface information and the attribute information.

Step 102, the first electronic device performs screen projection through the second electronic device based on the first screen projection mode.

The second electronic device and the first electronic device are in the same local area network.

Optionally, the display interface is a background interface, and the interface information is a background running program, so that the step 102 may be specifically implemented through the following steps 102a to 102 c.

Step 102a, the first electronic device obtains a background running program.

It may be appreciated that the background interface includes at least one application identifier, each application identifier being configured to indicate an application program running in the background, and the first electronic device obtaining the background running program according to the at least one application identifier.

Step 102b, the first electronic device determines the priority of the background running program.

It can be appreciated that the priority of the background running program can be determined according to the user usage habit (the frequency of usage of each application program by the user in a statistical period of time, or the probability of usage of each application program by the user in a statistical period of time) or the application program priority preset by the user.

Illustratively, the priority is determined according to the frequency of use of each application program in a period of time, the priority of high frequency of use is high, and the priority of low frequency of use is low; or the probability of using each application program in the current period of a day determines the priority, the priority with high use probability is high, and the priority with low use probability is low; or determining the priority according to the priority of the application program preset by the user, wherein the priority set by the user is high and the priority set by the user is low.

Step 102c, the first electronic device determines a preloaded screen-throwing mode based on the priority of the background running program.

Wherein the preloaded screen projection mode is a first screen projection mode.

It can be understood that, the user may determine the screen projection mode used by the application program with the highest priority (hereinafter referred to as the first application program) in the background running program as the preloaded screen projection mode, and then establish screen projection with the second electronic device based on the preloaded screen projection mode.

In the embodiment of the application, the screen projection or screen projection switching can be rapidly realized by determining the preloaded screen projection mode.

Illustratively, in an online video playing state (alternatively, the video application may be in a full-screen playing state or a non-full-screen playing state), the first screen-throwing mode is a push screen-throwing mode, as shown in fig. 3, and if the video application is in the current video playing state (alternatively, the video application may be in the full-screen playing state or the non-full-screen playing state) indicated by a mark "1", or the user clicks a "full-screen playing" button indicated by a mark "2", or the user clicks a "push to TV" button indicated by a mark "3", the push screen-throwing mode is determined as the first screen-throwing mode; under the condition that the first electronic equipment displays a desktop, an album, a setting, any APP interface except an online playing streaming media interface and the like, the first screen-throwing mode is a mirror image screen-throwing mode, as shown in fig. 4, the current process is the desktop, and the mirror image screen-throwing mode is determined to be the first screen-throwing mode.

The current screen-drop service and usage experience is split in terms of user experience. As shown in fig. 5, taking a mobile phone screen-throwing television as an example, in the process of using the screen-throwing television, if a user needs to throw the content such as a system desktop, an application program and the like (that is, needs to share the content with other users in a mirror image screen-throwing mode indicated by a mark "4"), and needs to throw the content such as an online video and the like (that is, needs to watch the online video in a push screen-throwing mode indicated by a mark "5") for meeting the user's requirements, the user needs to manually switch between the mirror image mode and the push mode, the steps are complicated, and the stopping and restarting of the screen-throwing service causes that the television screen is continuously blacked or returned to the front page, thereby seriously affecting the user experience.

In the embodiment of the present application, under the condition of at least two preset screen-throwing modes, the first electronic device may automatically determine selection and switching of the screen-throwing modes according to a process operated by a system foreground and user operation, without selecting a corresponding function in a setting interface by a user.

Optionally, before the step 101, the screen projection method provided in the embodiment of the present application may further include the following steps 103 to 104.

Step 103, the first electronic device receives a first input of a user.

The first input is used for starting a part of screen projection modes or all screen projection modes in at least two screen projection modes.

It will be appreciated that in the embodiments of the present application, the first input is used to activate at least one of the at least two modes of screen projection, i.e., the first input is used to activate all of the at least two modes of screen projection, two, … … and more … ….

Illustratively, the at least two modes of projection include a mirror projection mode and a push projection mode, and the first input is for initiating at least one of: mirror image screen projection mode, push screen projection mode. For example, the first input is used to initiate a mirror screen projection mode, or the first input is used to initiate a push screen projection mode, or the first input is used to initiate a mirror screen projection mode and a push screen projection mode.

Optionally, the first input may be a click input of the user to the screen of the first electronic device, or may be a slide input of the user to the screen of the first electronic device, or may be other feasibility inputs, which is not limited in the embodiments of the present application.

The click input may be any number of click inputs such as a single click input and a double click input, or may be a long press input or a short press input; the above-described slide input may be any slide input in any direction, for example, a left slide input, a right slide input, a downward slide input, or an upward slide input, or may be a two-finger slide input, a three-finger slide input, or the like.

The first input may be, for example, a user input to a target control, where the target control is used to control initiation of a partial or full screen mode of the at least two screen modes.

Step 104, the first electronic device responds to the first input, and starts a screen projection mode corresponding to the first input in at least two screen projection modes or starts at least two screen projection modes.

It may be appreciated that, in the embodiment of the present application, when the user controls the first electronic device to start at least one of the at least two screen modes, the first electronic device may start the at least one screen mode, or the first electronic device may also automatically start other screen modes of the at least two screen modes when the at least one screen mode is started (i.e., the first electronic device starts all screen modes of the at least two screen modes). Therefore, the electronic equipment can start all the screen-throwing modes in the at least two screen-throwing modes in a short time (for example, simultaneously), and when the first electronic equipment determines that the screen-throwing mode needs to be replaced, the first electronic equipment is not required to be controlled to start the screen-throwing mode through user input, so that the operation process can be simplified, the operation time is saved, and the operation efficiency is improved.

Illustratively, the at least two modes of projection include a mirror projection mode and a push projection mode. As shown in fig. 6, the user clicks on the "mirror image screen mode" option in the system setup menu or the control center, and then the first electronic device starts the mirror image screen mode, and at the same time starts the push screen mode. As shown in fig. 3, the user clicks a "TV push button" in an application program (such as various online video play APP) supporting the push screen mode, and then the first electronic device starts the push screen mode, and at the same time starts the mirror screen mode. That is, in the embodiment of the present application, no matter what operation is performed, once a certain screen-throwing mode is started, another screen-throwing mode is started, and the started screen-throwing mode is in a standby state.

Illustratively, the at least two modes of projection include a mirror projection mode and a push projection mode. The first electronic device may be provided with a unique screen switch, and the unique screen switch may simultaneously start the mirror image screen mode and the push screen mode (i.e. be responsible for simultaneously controlling the sending request and the working state of the mirror image mode and the push mode). The first electronic device can automatically select a corresponding screen projection mode according to the current foreground running process or user operation.

Optionally, before the step 101, the screen projection method provided in the embodiment of the present application may further include a step 105 described below.

Step 107, the first electronic device acquires a screen projection mode supported by the second electronic device.

Step 108, the first electronic device determines a screen projection mode supported by both the first electronic device and the second electronic device and stores the screen projection mode as a preset screen projection mode.

In the embodiment of the application, the first electronic device and the second electronic device establish connection, and after the first electronic device determines the preset screen projection mode supported by the first electronic device and the second electronic device based on the screen projection mode supported by the second electronic device and the screen projection mode supported by the first electronic device, the first screen projection mode can be better determined based on the interface information.

Optionally, before the step 106, the screen projection method provided in the embodiment of the present application may further include the following steps 109 to 110, where the step 106 may be specifically implemented by the following step 106 a.

Optionally, the second input may be a click input of the user to the first identifier, a slide input of the user to the first identifier, or another feasibility input, which is not limited in the embodiment of the present application.

For example, the descriptions of the click input and the slide input in the above step 103 may refer to the related descriptions of the click input and the slide input in the description of the first input, which are not described herein.

Step 106a, the first electronic device responds to the second input, establishes connection with the second electronic device, and stores the connection information.

Wherein, the connection information is: connection information between a first electronic device and a second electronic device in the same local area network.

Alternatively, the connection information may include an address of the second electronic device, and may further include second electronic device display attribute information. The display attribute information of the second electronic device may include resolution, frame rate, brightness, and the like of the second electronic device, which is not limited in the embodiment of the present application.

It can be appreciated that in the embodiment of the present application, the first electronic device stores the connection information in the storage area of the first electronic device.

In this embodiment of the present invention, the first electronic device stores the connection information, and when the electronic device needs to perform screen-casting connection or needs to switch screen-casting connection, the first electronic device may send, according to the stored connection information, a request message carrying a corresponding screen-casting protocol to the second electronic device, so as to establish screen-casting connection with the second electronic device.

In this embodiment of the present application, under the condition of at least two preset screen-throwing modes, no matter what screen-throwing mode is currently selected by the user, and then, the screen-throwing mode is switched to, only when connection is first established with the second electronic device, the user is required to select the second electronic device from a plurality of electronic devices in the same local area network, and then (because the connection information is stored in the first electronic device), no user operation is required, so that the electronic device for establishing the screen-throwing connection is reselected.

Optionally, the storing the connection information by the first electronic device may specifically store the connection information for the first electronic device into at least two screen projection protocols respectively. Wherein each screen projection protocol corresponds to one of at least two screen projection modes.

After the first screen projection channel is established, if the first screen projection mode is a mirror image screen projection mode, the first electronic device records screen content in real time, the screen content is transmitted to the second electronic device through the first screen projection channel, and then the second electronic device plays the recorded screen content (mirror image screen projection content) after receiving the screen content. If the first screen projection mode is the push screen projection mode, the second electronic device acquires corresponding streaming media content from the streaming media link through the first screen projection channel based on the streaming media link carried in the first request message, and then plays the streaming media content.

For example, as shown in fig. 8, S1, the first electronic device sends a first request message to the second electronic device, S2, the second electronic device sends a response message to the first electronic device, S3, (mirror screen-projection mode) the first electronic device sends mirror screen-projection content to the second electronic device, S4, (push screen-projection mode) the second electronic device obtains the streaming media content from the network (through the streaming media link).

Even in the case where a screen-drop connection has been established between two electronic devices, it is still necessary to go through the above steps.

The two screen projection modes (mirror image screen projection mode and push screen projection mode) have distinct and complementary advantages and disadvantages. The mirror image screen projection mode can completely transmit any picture of the small-screen electronic equipment to a large screen in real time, including but not limited to streaming media content such as photos, videos and music, and can also realize screen projection sharing of system pictures, setting menus, any APP interfaces and video feed stream interfaces, so that all members can participate in the current scene together conveniently, such as discussion of issues, film selection and man-machine interaction; however, the mirror image screen-throwing mode has the problems of larger picture delay and lower quality. The push screen-throwing mode can realize screen throwing of pictures with high resolution and high frame rate, and viewing experience is improved; but is only suitable for streaming media content, so the adaptability to screen content is poor, and the coverage is limited.

Optionally, before the step 111, if the first electronic device is operated in the second screen-projection mode, the first electronic device continues to operate in the second screen-projection mode before the step 112.

Correspondingly, the second electronic device receives the first request message specifically includes: the second electronic device receives a first request message from the first electronic device during a screen projection based on a second screen projection mode (the first screen projection data is transmitted through a second screen projection channel). The second electronic device establishes a first screen projection channel based on the first request message specifically comprises: in the process of performing screen projection (transmitting first screen projection data through a second screen projection channel) based on the second screen projection mode, the second electronic equipment establishes the first screen projection channel based on the first request message.

After the first screen projection channel is established, the first electronic equipment stops to project the screen with the second electronic equipment through the second screen projection mode, and starts to control the first electronic equipment to keep to project the screen with the second electronic equipment through the second screen projection mode. It can be understood that the first electronic device controls the first electronic device to operate in the first screen projection mode.

Correspondingly, the second electronic device switches the transmission of the first screen projection data through the second screen projection channel to the transmission of the second screen projection data through the first screen projection channel.

Under the condition of at least two preset screen projection modes (screen projection services), when the second electronic equipment receives a first request message and detects that the first screen projection mode indicated in the first request message is inconsistent with the last matched screen projection mode (second screen projection mode), a new screen projection channel (first screen projection channel) is established under the condition of keeping the original screen projection channel (second screen projection channel) open (transmitting first screen projection data through the second screen projection channel). When the new screen-throwing channel is built, the second electronic equipment transmits second screen-throwing data (new screen-throwing data) through the first screen-throwing channel, so that the processes of displaying a black screen, waiting for loading, waiting for reconnection and the like in the screen-throwing mode switching process (gap) can be avoided, and further the coherent experience of a user is influenced.
