The present disclosure relates to the field of computer technologies, and in particular to a screen projection control method, apparatus, device and medium.
With the continuous development of Internet of Things and Internet technologies, screen projection is gradually becoming one of mainstream video viewing methods. In general, the screen projection is mainly to display content displayed on a small-screen mobile terminal on a large-screen display terminal through an interaction between the small-screen mobile terminal and the large-screen display terminal, so that the content displayed on the small-screen mobile terminal can be viewed through the large-screen display terminal.
In the related art, before the screen projection is realized through the interaction between the small-screen mobile terminal and the large-screen display terminal, it is necessary for the large-screen display terminal to be started up first, and then a connection is established between the large-screen display terminal and the small-screen mobile terminal after the large-screen display terminal is started up, so that the content displayed on the small-screen mobile terminal can be played through the large-screen display terminal.
In the above implementation process, it usually takes 10 to 30 seconds from starting up the large-screen display terminal to playing the content, resulting in the relatively low screen projection efficiency and inability to rapidly respond to screen projection requirements of a user.

Referring to
Step 201, in response to detecting a setting operation, a first electronic device sends a first packet to the second electronic devices that have been paired, wherein the first packet is configured to control the second electronic devices to start up in a screen-off state.
The first electronic device and the second electronic device may be paired in advance. Optionally, the first electronic device may be paired with a plurality of second electronic devices in advance. The first packet can also be called a wake up packet (WUP), a magic packet, and the like.
It should be noted that the screen-off state is a state in which the second electronic device is powered on, but a screen thereof in an off state. Taking the screen of the second electronic device as an LCD screen as an example, the screen-off state can be to turn off a backlight system of the second electronic device. Taking the screen of the second electronic device as an OLED screen as an example, the screen-off state can be that the OLED display of the second electronic device is turned off.
Step 202, in response to receiving the first packet sent by the first electronic device that has been paired, the second electronic device starts up in the screen-off state.
Step 203, when the second electronic devices are in a start-up state, in response to receiving a screen projection instruction, the first electronic device sends screen projection data to the second electronic devices.
Step 204, in response to receiving the screen projection data sent by the first electronic device, the second electronic device controls the second electronic device to enter a screen-on state and displays the received screen projection data on a screen.
According to the embodiment of the present disclosure, by in response to detecting the setting operation, sending, by the first electronic device, the first packet to the second electronic device that has been paired to enable the second electronic device to start up in the screen-off state after receiving the first packet: when the second electronic device is in the start-up state, in response to receiving the screen projection instruction, the first electronic device can send screen projection data to the second electronic device to enable the second electronic device to directly light up the screen after receiving the screen projection data and display the screen projection data without controlling the second electronic devices to start up, thereby saving the time consumption of the process of the screen projection, improving the efficiency of the screen projection, and further improving the user experience.
After introducing the basic implementation process of the present disclosure, various non-limiting embodiments of the present disclosure are described below.
In some embodiments, the first electronic device and the second electronic device may be paired in advance. Optionally, the first electronic device can be installed with a target application, and the second electronic device can be configured with a target function, therefore, the first electronic device can be paired with the second electronic device through the target application installed in the first electronic device and the target function configured in the second electronic device.
The target application can be an application supporting wake on lan (WOL), for example, the target application can be an application supporting wake on wlan. Optionally, the target application can also be an application supporting other wake on lan methods, and the present disclosure is not limited to which manner is specifically adopted to realize wake on lan. In one possible implementation, the target application can be a magic packet, and the first electronic device can download the target application through a browser, an application market, and the like.
The target function can be a wake on lan function, for example, a WOL function, and the second electronic device can be configured to support the target function at the factory, so that the second electronic device can realize a remote wake up through the target function when the target function is turned on and the second electronic device is powered on but not started up. Optionally, a user can also turn off the target function of the second electronic device by himself/herself. Referring to
Further, when the target function is turned off, the user can turn on the target function of the second electronic device again through the setting interface shown in
A flowchart described in the above process can be seen in
In one possible implementation, the first electronic device can be paired with the second electronic device through the following method:
That is, the second electronic device can send the MAC address of the second electronic device to the first electronic device through the target function, so that the first electronic device can obtain the MAC address of the second electronic device through the installed target application. Optionally, the first electronic device can store the MAC address of the second electronic device, so that the first electronic device and the second electronic device can share the MAC address of the second electronic device.
In addition, in the case that the first electronic device and the second electronic device share the MAC address of the second electronic device, the first electronic device and the second electronic device can also share a preset password, so that the first electronic device can be paired with the second electronic device under the condition of sharing the MAC address and the preset password of the second electronic device.
In a process that the first electronic device and the second electronic device share the preset password, the second electronic device can randomly generate a preset password and store the generated preset password: further, the second electronic device can send the generated preset password to the first electronic device, and the first electronic device can store the received preset password when receiving the preset password sent by the second electronic device, so that the first electronic device and the second electronic device can share the preset password. Optionally, the preset password can also be generated by the first electronic device and sent to the second electronic device by the first electronic device, which is not limited by the present disclosure.
Optionally, the preset password can be a random combination of a series of numbers, letters or symbols, or the preset password can be a combination of any two or three types of characters among numbers, letters and symbols, and the present disclosure does not limit the specific character types included in the preset password. The preset password can be 4 or 6 digits. In more possible implementations, a number of digits of the preset password can be more or less, and the present disclosure does not limit the number of digits of the preset password.
By sharing the MAC address of the second electronic device, or sharing the MAC address and password of the second electronic device with the first electronic device, the first electronic device can be paired with the second electronic device, so that the first electronic device can directly send the first packet to the paired second electronic device.
Optionally, a first electronic device can be paired with a plurality of second electronic devices, and a second electronic device can also be paired with a plurality of first electronic devices, which is not limited by the present disclosure. The above description only takes a process of pairing a first electronic device with a second electronic device as an example, and a process of pairing the first electronic device with the second electronic device with different device types can be the same as the above process, which will not be repeated here.
After the first electronic device is paired with the second electronic device through the above process, the first electronic device can send the first packet to the paired second electronic device through step 201 when the setting operation is detected.
In some embodiments, for step 201, in response to detecting the setting operation, sending the first packet to the second electronic devices that have been paired can be realized through the following step:
It should be noted that since the first electronic device can be paired with the plurality of second electronic devices, the first electronic device can send the first packet to the plurality of second electronic devices located within the setting range when the setting operation is detected, and the first packet can be sent to the plurality of second electronic devices at the same time through the broadcast.
The setting operation can be that a position of the first electronic device changes, for example, the first electronic device is picked up: or, the setting operation can also be an operation event of a setting type occurs in a setting application in the first electronic device, wherein the setting application can be a multimedia application, for example, a video playing application, and the operation event of the setting type can be that the setting application is opened. Optionally, the setting operation can also be other types of operations, and the present disclosure does not limit the specific type of the setting operation.
Optionally, the setting range can be a circular range with a location of the first electronic device as a center and a setting distance as a radius, or the setting range can be of other types, which is not limited by the present disclosure.
It should be noted that when the first electronic device sends the first packet to the plurality of second electronic devices through the broadcast, not all the second electronic devices that have been paired with the first electronic device and are powered on but not started up can receive the first packet. In one possible implementation, only a plurality of second electronic devices that have been configured to turn on the target function in advance can receive the first packet sent by the first electronic device, that is, it is necessary for respective second electronic devices to receive the first packet through the target function; in other words, the second electronic devices can only receive the first packet sent by the first electronic device through the target function when the target function is turned on.
In one possible implementation, the second electronic device can supply power to a random access memory (RAM), a micro control unit (MCU), an Ethernet unit and a wireless overlay network unit of the second electronic device when a power supply is turned on, so as to support the second electronic device to receive the first packet sent by the first electronic device through the target function.
The random access memory can be a synchronous dynamic random access memory (SDRAM), for example, a double data rate synchronous dynamic random access memory (DDR SDRAM, referred to as DDR). Optionally, the random access memory can be of other types, which is not limited by the present disclosure. The wireless overlay network unit can be a WiFi unit, and optionally, the wireless overlay network unit can be of other types, which is not limited by the present disclosure.
The above random access memory, the micro control unit, the Ethernet unit and the wireless overlay network unit can be used as continuous power supply parts of the second electronic device, when the second electronic device is powered on, these parts can be powered on to support the target function through these parts, so that the second electronic device can receive the first packet through the target function. Optionally, the second electronic device can receive the first packet through a physical layer (PHY) device, for example, the first packet can be received through a network card.
It should be noted that a purpose of setting the continuous power supply parts is to ensure that the second electronic device can be awakened by functions of a remote controller such as an infrared (IR), a key press and a WOL in a standby state, so that the second electronic device can enter a normal working state.
Referring to
The above process of pairing the first electronic device with the second electronic device and then waking up the second electronic device through the first electronic device can be seen in
It should be noted that since the first electronic device sends the first packet by broadcast, that is, a plurality of second electronic devices can receive the first packet sent by the first electronic device, in this case, a verification method can be provided, so that the second electronic device can determine whether the received first packet is to be sent to itself, and then communication between the first electronic device and a specific second electronic device can be realized.
The first packet can include the MAC address of the second electronic device, so that a plurality of second electronic devices can perform verification on the MAC address included in the received first packet to determine whether the received first packet is to be sent to themselves. In this case, a packet format of the first packet can be FF FF FF FF FF FF plus the MAC address (repeated 16 times).
Optionally, on the premise that the first packet includes the MAC address of the second electronic device, the first packet can also include a preset password, so that the plurality of second electronic devices can perform the verification on the MAC address and the preset password included in the received first packet to determine whether the received first packet is to be sent to themselves. In this case, a packet format of the first packet can be FF FF FF FF FF FF plus the MAC address (repeated 16 times) plus the preset password.
In some embodiments, for step 202, in response to receiving the first packet sent by the first electronic device that has been paired, starting up in the screen-off state can include the following steps.
Step 2021, in response to receiving the first packet, the second electronic device performs verification on the MAC address included in the first packet.
When the first packet includes the MAC address of the second electronic device, in response to receiving the first packet. the second electronic device can compare the MAC address of the second electronic device included in the received first packet with the MAC address of the second electronic device itself to perform verification on the first packet.
When the first packet includes the MAC address of the second electronic device and the preset password. in response to receiving the first packet, the second electronic device can compare the MAC address of the second electronic device included in the received first packet with the MAC address of the second electronic device itself, and compare the preset password included in the received first packet with the stored preset password of the second electronic device itself to perform verification on the first packet.
Step 2022, in response to that the MAC address passes the verification, the second electronic device starts up in the screen-off state.
In the case that the first packet includes the MAC address of the second electronic device, if the MAC address of the second electronic device included in the first packet is consistent with the MAC address of the second electronic device itself, the second electronic device can determine that the first packet has passed the verification, and the second electronic device can start up in the screen-off state in response to passing the verification.
The above process is described by taking that the first packet only includes the MAC address of the second electronic device as an example. however, the first packet can also include the preset password. When the first packet includes the MAC address of the second electronic device and the preset password, for step 2021, the second electronic device can perform verification on the MAC address and the preset password while performing verification on the first packet. In one possible implementation, the second electronic device can compare the MAC address of the second electronic device included in the received first packet with the MAC address of the second electronic device itself, and compare the preset password included in the received first packet with the stored preset password of the second electronic device itself to perform verification on the first packet.
Based on this, for step 2022, if the MAC address of the second electronic device included in the first packet is consistent with the MAC address of the second electronic device itself, and the preset password included in the received first packet is consistent with the stored preset password of the second electronic device itself, the second electronic device can determine that the first packet has passed the verification, and the second electronic device can start up in the screen-off state in response to passing the verification.
In some embodiments, the second electronic device starts up in the screen-off state can be realized through the following step:
Taking the second electronic device shown in
The above process is described by taking that the second electronic device starts up in the screen-off state after receiving the first packet as an example. It should be noted that the second electronic device can be set to a low-power screen projection mode in advance, so that the second electronic device can start up in the screen-off state in the low-power screen projection mode after receiving the first packet.
In one possible implementation, the user can perform a mode setting operation on the second electronic device, and the second electronic device can set the second electronic device to the low-power screen projection mode in response to the mode setting operation on the second electronic device, so that the second electronic device can start up in the screen-off state in the low-power screen projection mode.
For example, the second electronic device can display a mode setting function entry on a visual interface of the second electronic device, and the user can trigger the mode setting function entry, and in response to a trigger operation of the mode setting function entry, the second electronic device can display a mode setting interface to perform the mode setting operation in the mode setting interface.
Referring to
It should be noted that the user can set the low-power screen projection mode at any time. For example, the user can set the second electronic device to the low-power screen projection mode before the second electronic device is turned off, or the user can set the second electronic device to the low-power screen projection mode after the second electronic device is turned on, for example, the second electronic device can be set to the low-power screen projection mode at any time in an use process after the second electronic device is turned on, and the present disclosure does not limit the specific time when the second electronic device is set to the low-power screen projection mode.
In a formal mode, the second electronic device should normally enter a desktop, a system interface, an Android desktop launcher page, or the like. When the second electronic device is set to the low-power screen projection mode, a system can be started up in response to turning off a backlight, that is, system can be started up in the screen-off state, so that unnecessary functions such as the backlight can be turned off to save energy consumption of the second electronic device. In addition, the user can also exit the low-power screen projection mode or turn the second electronic device off through a remote controller, thereby improving the flexibility of a process of controlling the screen projection.
Optionally, after starting up in the screen-off state, the second electronic device can send feedback information to the first electronic device, wherein the feedback information is used to indicate that the second electronic device has been started up in the screen-off state, so that the first electronic device can determine that the second electronic device has been started up in the screen-off state after receiving the feedback information, and subsequent processes of the screen projection can be carried out.
Based on this, for step 203, when the second electronic devices are in the start-up state, in response to receiving the screen projection instruction, sending, by the first electronic device, the screen projection data to the second electronic devices can be realized through the following step:
The screen projection instruction can be triggered by the user in a specific application developed by the screen projection control method provided by the present disclosure. The specific application can be dedicated to providing a screen projection function, or the specific application can be associated with other applications in the first electronic device, so that the user can trigger screen projection of pages of other applications associated with the specific application through the specific application. Other applications associated with the specific application can be various types of applications, for example, video play applications.
In addition, the screen projection instruction can also be triggered by the user in an application supporting the screen projection function, for example, the video play applications supporting the screen projection function. In one possible implementation, a display page of the application supporting the screen projection function can include a screen projection control, and the user can trigger the screen projection control to trigger the screen projection of the page of the application supporting the screen projection function.
The above are only two exemplary methods to trigger the screen projection instruction. In more possible implementations, the screen projection instruction can be triggered by other methods, and the present disclosure does not limit the specific trigger mode of the screen projection instruction.
The screen projection data can be video data, image data, text data, and the like. The present disclosure does not limit the specific data type of the screen projection data.
It should be noted that after the first electronic device sends the screen projection data to the second electronic device in step 203, the second electronic device can light up the screen in step 204 to display the received screen projection data.
Taking the second electronic device shown in
Optionally, the transmission and reception of the screen projection data between the first electronic device and the second electronic device can be realized by means of digital living network alliance (DLNA) technologies, wireless authentication (Miracast) technologies or airplay technologies. The present disclosure does not limit which method is specifically adopted.
It should be noted that the processes described in the above respective embodiments can be seen in
In some embodiments, after the screen projection between the first electronic device and the second electronic device is realized through the above steps 201 to 204, the content being played in the screen of the second electronic device can also be adjusted through the first electronic device.
That is, after step 204, the method can further include the following steps.
Step 205, in response to detecting a play adjustment operation, the first electronic device sends a play adjustment instruction to the second electronic devices, wherein the play adjustment instruction is configured to control the second electronic devices to adjust content being played on a screen.
The play adjustment operation can include a pause operation, a fast forward operation, a fast backward operation, a double-speed play operation, an exit operation, and the like. The play adjustment operation can be triggered by the user in the first electronic device. For example, different controls can be set for different types of play adjustment operations in a visual interface of the first electronic device, and the user can trigger the corresponding types of play adjustment operations by triggering the corresponding controls. For example, the user can trigger the pause operation by triggering a pause control, and for example, the user can trigger the fast forward operation by triggering a fast forward control, and the like.
The first electronic device can generate a play adjustment instruction when detecting the play adjustment operation, and then send the play adjustment instruction to the second electronic device.
It should be noted that since the play adjustment operation can include various types of operations, the play adjustment instruction generated based on the play adjustment operation can also adjust different types of contents being played. For example, the play adjustment instruction generated based on the pause operation can be used to control the second electronic device to pause the content being played on the screen, and for example, the play adjustment instruction generated based on the fast forward operation can be used to control the second electronic device to fast forward the content being played on the screen.
Step 206, in response to receiving a play adjustment instruction sent by the first electronic device, the second electronic device adjusts content being played on the screen.
It should be noted that after receiving the play adjustment instruction, the second electronic device can make a corresponding adjustment to the content being played on the screen based on the received play adjustment instruction, including but not limited to, pause, fast forward, fast backward, double-speed play, exit, and the like.
Optionally, when performing the play adjustment of the screen projection data between the first electronic device and the second electronic device, it can also be realized by means of the DLNA technologies, the Miracast technologies or the Airplay technologies, and the like, and the present disclosure does not limit which method is specifically adopted.
The above embodiment provides a way to control the second electronic device to adjust the content played by the second electronic device through the first electronic device after screen projection, so that the user can adjust the content played by the second electronic device without operating on the second electronic device, thereby improving the flexibility of a process of controlling the screen projection.
It should be noted that the processes described in the above respective embodiments can be seen in
In more possible implementations, in a process that the second electronic device displays the received screen projection data, the user can control the second electronic device to turn off by remote control. In addition, after finishing playing the screen projection data sent by the first electronic device, the second electronic device exits the display and enters the low-power screen projection mode again, that is, the screen will wait for the first electronic device to project again. Optionally, the second electronic device can also be automatically turned off after a period of inactivity.
It should be noted that the processes described in the above respective embodiments can be seen in
By waiting for the screen projection of the first electronic device after the screen projection data sent by the first electronic device is played, the power consumption of the second electronic device can be effectively reduced, thereby improving the service life of the second electronic device.
