For convenience of understanding, the following embodiments of the present application will specifically describe a screen projection method of an electronic device provided in the embodiments of the present application, by taking the electronic device having the structure shown in fig. 4 and 5 as an example, with reference to the accompanying drawings.

The screen projection method of the electronic device provided in the embodiment of the present application may be applied to the system architecture shown in fig. 6, and a processing flow of the embodiment of the present application is described below with reference to fig. 6.

First, the SystemUI is operated in the Android system in the form of a system application, and the above-described (b) diagram in fig. 1 and (a) diagram in fig. 2 are quick settings (quick settings) among the functions implemented by the SystemUI. After the user clicks the "wireless screen projection" button in the diagram (b) in fig. 1 or the diagram (a) in fig. 2 (or finds the "wireless screen projection" button through the "setting" path of the electronic device), the electronic device may send the click instruction to the wireless screen projection module of the business layer. The wireless screen projection module searches for the screen projection device through a mirror image protocol provided by a screen projection capability center, for example, searches through a Miracast protocol, then calls a wireless video display manager WiFiDisplay of an application framework layer, and determines to connect with a Wifi peer-to-peer (P2P) screen projection device through a multi-screen interaction framework. After the electronic device is connected with the screen projection device, a data stream of a display interface can be pushed to the screen projection device for displaying, and a state identifier of the opened mirror image screen projection is written into a configuration file Settings and device information of the connected screen projection device is written into a DataBase SQLite (DataBase), which is hereinafter referred to as DB for short. Optionally, the state identifier and the device information may also be written in other storable files, and the storage manner is not limited in the embodiments of the present application. Then, if the third-party video APP is playing a video, the video APP reads the state identifier in Settings and the device information in the DB through an interface provided by the system. When the read state identification is that the mirror image screen projection is started and the DB contains connected equipment information, the video APP calls a DLNA interface inside the system, the mirror image screen projection is converted into DLNA screen projection, and DLNA screen projection connection success information is sent to the wireless screen projection module. It is understood that the device information in the DB may include, but is not limited to, an IP address, a Mac address, a uuid, a device identification, a device name, etc. of the screen-casting device. Generally, video data for mirror projection is in an H264 video coding format, and video data for DLNA projection is in an x264 video coding format.

When the wireless screen projection module searches for the screen projection equipment through the mirror image protocol, the corresponding mirror image protocol can be preferentially selected according to the capability of the current screen projection equipment, and the current popular mirror image protocols comprise a Miracast protocol, a Cast + protocol, an AirPlay protocol, a Lelink protocol and the like.

Specifically, miracast is a wireless display standard established by a Wi-Fi alliance in 2012 and based on Wi-Fi Direct (Wi-Fi Direct), a wireless local area network does not need to be accessed by a device which performs wireless screen projection by adopting a Miracast protocol, and an electronic device can directly play videos or photos on the screen projection device through the protocol without any connecting line or wireless Access Point (AP); in the Miracast application scenario, one P2P-capable smart phone may be directly connected to one P2P-capable smart tv, and the smart phone may transmit its own screen or media resource to the smart tv for display or playing. The Cast + protocol can support electronic equipment of a fixed brand A to conduct wireless screen projection, and the packet loss rate is low in the audio and video data transmission process. The AirPlay protocol is a wireless display standard based on wifi, can be applied between electronic equipment of a fixed brand B and screen projection equipment, and supports a push mode and a mirror mode. The equipment adopting the Lelink protocol for wireless screen projection needs to be accessed to the same wireless local area network.

The screen projection method of the electronic device provided by the embodiment of the present application can also be applied to the system architecture shown in fig. 7, and a processing flow of the embodiment of the present application is described below with reference to fig. 7.

First, when the third-party video APP is playing a video, a user clicks a "wireless screen projection" button in (b) of fig. 1 or (a) of fig. 2 (or finds the "wireless screen projection" button through a "setting" path of the electronic device). Then, if the wireless screen projection module of the service layer monitors that the video APP is playing a video, the screen projection device can search through a mirror image protocol provided by the screen projection capability center, for example, through the Miracast protocol, at this time, the screen projection capability center opens a P2P or wlan connection channel, and establishes a channel with a WiFi P2P screen projection device through a WiFi P2PManager manager, or establishes a channel with a WiFi (STA) screen projection device. In one implementation, as shown in (a) of fig. 7, after the channel is established, the screen-casting capability center does not push a data stream to the display manager DisplayManager, but the multi-screen interaction framework still writes the status identifier of the opened mirror screen casting into the configuration file Settings and the device information of the connected screen casting device into the DB. And then, if the third-party video APP monitors that the mirror image screen projection of the electronic equipment is started, calling a DLNA interface in the system to carry out DLNA screen projection.

In another realizable way, as shown in (b) of fig. 7, after the above-mentioned setup of the channel, the screen-casting capability center pushes the data stream to the DisplayManager, but the data stream is filtered out by the DisplayManager, i.e., not displayed on the screen-casting device. And then writing the state identification of the opened mirror image screen projection into a configuration file Settings and writing the equipment information of the connected screen projection equipment into the DB by the multi-screen interaction framework. And if the third-party video APP monitors that the mirror image projection screen of the electronic equipment is started, calling a DLNA interface in the system to carry out DLNA projection screen.

In summary, when the mirror image is projected, the screen projection device has the problems of the black edge of the screen and the like, and after the mirror image screen projection function is started, the video APP can call the internal DLNA interface to automatically turn to DLNA screen projection. When the DLNA (digital living network alliance) of the electronic equipment is used for projecting a screen, the address of the played audio and video data (such as a Uniform Resource Locator (URL)) can be pushed to the screen projecting equipment, the screen projecting equipment can download data resources according to the address of the audio and video data, full-screen playing is further achieved, the problems of black edge, blockage, unsynchronized flower screen and sound picture and the like of the picture can be reduced, the played video picture is clear and smooth, the screen projecting effect is effectively improved, other operations are not needed for a user, and the experience degree of the user is also improved. In addition, by adopting a DLNA screen projection mode, a user can execute other operations on the electronic equipment without influencing the normal video playing of the screen projection equipment.

First, a process of implementing the scene in fig. 1 is described, that is, a scene in which the electronic device first plays a video and then opens a mirror image for screen projection is introduced, and with reference to the system architecture shown in fig. 6, fig. 8 is a schematic flowchart of a screen projection method for the electronic device according to an embodiment of the present application, where the method includes:

s201, receiving video playing operation of the electronic equipment, and acquiring a state identifier of the electronic equipment.

When the electronic device is in the mirror image screen projection state, the state identifier may be 1, and when the electronic device is not in the mirror image screen projection state, the state identifier may be 0.

S202, determining that the electronic equipment is not in a mirror image screen projection state through the state identification, receiving screen projection operation of a user, and projecting the screen to the screen projection equipment by the electronic equipment in a mirror image screen projection mode.

Specifically, when the electronic device is not yet in the state of mirror image screen projection (that is, the state identifier is 0), if the video APP in the electronic device starts to play the video, the screen cannot be projected on the screen projection device, and at this time, the user is required to open the function of mirror image screen projection (that is, screen projection operation).

After a user opens the mirror image screen projection function, the electronic equipment can search the equipment through the mirror image protocol, and when the electronic equipment only searches one screen projection device, the electronic equipment can directly project the display interface mirror image to the screen projection device. When the electronic device searches for multiple screen projection devices, a list of available devices may be displayed to a user, such as the display interface shown in fig. 1 (c), and then, after receiving a selection operation of the user, the electronic device projects a display interface mirror image to the screen projection device selected by the user. When the screen projection device searched by the electronic device is the screen projection device selected by the user before, the display interface can be directly projected to the screen projection device in a mirror image mode. It can be understood that after the display interface of the electronic device is projected to the screen projection device in a mirror image manner, the electronic device can record the state identifier of the opened mirror image screen projection and the device information of the connected screen projection device.

S203, first device information of the screen projection device is obtained, and the screen projection mode between the electronic device and the screen projection device is switched from mirror image screen projection to DLNA screen projection according to the first device information.

Specifically, after the electronic device is in a state of mirror image screen projection, the video APP can acquire device information of the screen projection device, an internal DLNA interface is called, and a screen projection mode between the electronic device and the screen projection device is switched from mirror image screen projection to DLNA screen projection. Before the video APP calls the internal DLNA interface, the electronic equipment needs to search nearby equipment supporting DLNA screen projection through a DLNA protocol, and when the equipment supporting DLNA screen projection and the screen projection equipment for mirror image screen projection are the same, the video APP can call the DLNA interface to realize DLNA screen projection. It should be noted that, the device that uses the DLNA protocol to perform wireless screen projection needs to access the same wireless lan.

For this process, as can be seen from the manner that the electronic device starts the mirror image screen projection mode to watch the video described in fig. 1, the manner is that the electronic device first plays the video and then starts the mirror image screen projection, and for this manner, the following description describes a process of switching to DLNA screen projection: referring to the diagram (a) in fig. 9, in the process of playing a video, if the current electronic device does not start the function of mirror image screen projection, the video APP starts the monitoring module ContentObserver to monitor the data in the Settings (that is, when the video APP plays a video, it monitors whether the electronic device is in the state of mirror image screen projection). When monitoring that the state identification in Settings is that the mirror image is opened and the screen is projected, namely the electronic device has the mirror image projected to the screen projecting device at the moment, and the video APP also plays the video at the moment, then the video APP acquires the device information of the connected screen projecting device from the DB again, and the screen projecting mode between the electronic device and the screen projecting device is switched from the mirror image projection to the DLNA projection. In addition, the ContentObserver can also monitor whether the mirror image screen projection is disconnected between the electronic device and the screen projection device, for example, after the mirror image screen projection is disconnected by the electronic device, the video APP monitors the disconnection message, and the internal DLNA interface is called to disconnect the DLNA screen projection.

According to the screen projection method of the electronic equipment, when the electronic equipment plays a video, if the electronic equipment is not in the state of system mirror image screen projection at present, the electronic equipment can receive the operation of starting the system mirror image screen projection function by a user, and the mirror image screen projection is switched into DLNA screen projection, so that the problems of picture black border, blockage, unsynchronized flower screen and sound and picture and the like are reduced, the played video picture is clear and smooth, the screen projection effect is effectively improved, other operations are not required for the user, and the watching experience of the user is also improved.

For the scenario in fig. 1, the system architecture shown in fig. 7 may also be implemented in combination, and fig. 10 is a schematic flowchart of a screen projection method of another example of electronic equipment provided in the embodiment of the present application, where the method includes:

s301, receiving video playing operation of the electronic equipment, and acquiring a state identifier of the electronic equipment.

The implementation process of S301 may refer to the process of S201 described above, and is not described herein again.

S302, determining that the electronic equipment is not in a mirror image screen projection state through the state identification, receiving screen projection operation of a user, and establishing channel connection between the electronic equipment and the screen projection equipment.

Specifically, when the electronic device is not yet in a state of mirror image screen projection, if a video APP in the electronic device starts playing a video, the screen cannot be projected on the screen projection device, and at this time, a user is required to open a function of mirror image screen projection (namely screen projection operation).

After a user opens the mirror image screen projection function, the electronic equipment can search equipment through a mirror image protocol, and after the screen projection equipment is searched, channel connection between the electronic equipment and the screen projection equipment is established. In an implementation mode, the electronic device and the screen projection device only establish channel connection, and data streams are not pushed to the screen projection device; in another implementation, the electronic device establishes a channel connection with the screen projection device and pushes a data stream to the screen projection device, but this data stream is filtered by the screen projection device. That is, in this implementation, the screen projection device does not display an interface of the electronic device mirror image screen projection.

It can be understood that after the electronic device and the screen projection device establish channel connection, the state identifier of the started mirror image screen projection and the device information of the connected screen projection device can also be recorded.

And S303, acquiring first equipment information of the screen projection equipment, and projecting the screen of the electronic equipment to the screen projection equipment in a DLNA screen projection mode according to the first equipment information.

Specifically, video APP can monitor whether the electronic equipment is in a state of mirror image screen projection, when the mirror image screen projection is started, the equipment information of the screen projection equipment is obtained, an internal DLNA interface is called, therefore, the electronic equipment does not mirror image screen projection to the screen projection equipment, the electronic equipment can be directly projected to the screen projection equipment in a mode of projecting the screen through the DLNA, and at the moment, no mirror image screen projection is conducted on the user view, and the switching process to the DLNA screen projection is conducted.

According to the screen projection method of the electronic equipment, when the electronic equipment plays a video, if the electronic equipment is not in a state of projecting a screen by a system mirror image currently, the electronic equipment can receive the operation of starting the screen projection function by a user, and the DLNA screen projection mode is directly adopted to project the screen to the screen projection equipment, so that the problems of picture black edges, blockage, unsynchronized flower screen and sound picture and the like are reduced, the played video picture is clear and smooth, the screen projection effect is effectively improved, other operations are not required for the user, and the viewing experience of the user is also improved.

Next, a process of implementing the scene in fig. 2 is introduced, that is, a scene in which the electronic device first opens the mirror image screen projection and then plays the video is presented, and with reference to the system architecture shown in fig. 6, fig. 11 is a schematic flowchart of a screen projection method of another example of the electronic device provided in the embodiment of the present application, where the method includes:

s401, receiving screen projection operation of a user, and projecting the screen to screen projection equipment by the electronic equipment in a mirror image screen projection mode.

The screen projection operation may be a click operation of the "wireless screen projection" button in the diagram (a) in fig. 2 described above by the user, or a click operation of the "wireless screen projection" button in the "setting" path of the electronic device. The mirror image screen projection process in this step can refer to the description of the above embodiments, and is not described herein again.

S402, receiving video playing operation of the electronic equipment, and acquiring screen projection information of the electronic equipment, wherein the screen projection information comprises first equipment information of the screen projection equipment.

And S403, switching the screen projection mode between the electronic equipment and the screen projection equipment from mirror image screen projection to DLNA screen projection according to the first equipment information.

Specifically, after the electronic equipment mirror image is projected to the screen projection equipment, the current screen projection information can be stored, if a video APP installed in the electronic equipment plays a video, the screen projection information is actively acquired by the video APP, an internal DLNA interface is called by the video APP in the state that the electronic equipment is in the mirror image screen projection, and the screen projection mode between the electronic equipment and the screen projection equipment is switched from the mirror image screen projection to DLNA screen projection.

For this process, as can be seen from the manner that the electronic device starts the mirror image screen projection mode to watch the video described in fig. 2, the manner is that the electronic device starts the mirror image screen projection first and then plays the video, and for this manner, a process of switching to DLNA screen projection is described below: referring to the diagram (b) in fig. 9, the electronic device is already in the mirror image screen projection mode, when the user clicks on the video APP to play a video, the video APP calls a system interface to obtain data in Settings and the DB, and if the state identifier in Settings is that the mirror image screen projection is started and the DB has device information of the connected screen projection device, the screen projection mode between the electronic device and the screen projection device is switched from the mirror image screen projection to the DLNA screen projection. This method is different from the method described in the above-mentioned diagram (a) of fig. 9 in that the method does not need to start the snooping module ContentObserver to actively snoop the state of the system image screen shot.

According to the screen projection method of the electronic equipment, when the electronic equipment plays a video, if the electronic equipment is currently in the state of screen projection of a system mirror image, the screen projection can be automatically switched to DLNA, so that the problems of black edge of a picture, blockage, unsynchronized flower screen and sound and picture and the like are solved, the played video picture is clear and smooth, the screen projection effect is effectively improved, other operations are not required for a user, and the watching experience of the user is also improved.

In an actual scene, when a DLNA screen projection device is adopted to project the electronic device to the screen projection device, the electronic device can be successfully switched to the DLNA screen projection device only by ensuring that the screen projection device determined by the DLNA protocol is the same as the screen projection device which is connected with the DLNA screen projection device (or the screen projection device which projects the screen in a mirror image mode). As can be seen from the above description, after the electronic device and the screen projection device are connected, the device information of the screen projection device may be recorded in the DB, where the device information includes an IP address, a Mac address, a uuid, a device identifier, a device name, and the like, and then the electronic device may search for an available screen projection device supporting DLNA screen projection through a DLNA protocol, obtain the device information of the available screen projection device supporting DLNA screen projection, compare the device information of the available screen projection device supporting DLNA screen projection with the device information in the DB, and if the comparison is successful, may switch the mirror image screen projection to DLNA screen projection.

In an implementable manner, the device information (1) of the screen projection device recorded in the DB (i.e. the device information of the screen projection device projected by the electronic device system image) comprises an IP address, and the device information (2) of the available screen projection device searched by the electronic device through the DLNA protocol also comprises the IP address. If the electronic equipment searches for the screen projection equipment through the mirror image protocol through the same wireless local area network, for example, a Lelink protocol is adopted, and the DLNA protocol searches for the available screen projection equipment through the same wireless local area network, so that the IP address of the obtained equipment information (1) is the same as the IP address of the equipment information (2), the video APP in the electronic equipment can directly obtain the IP address of the equipment information (1) from the DB, and the DLNA projects the screen to the screen projection equipment corresponding to the IP address, and the DLNA screen projection process is completed. Optionally, in this implementation, since the IP address of the device information (1) is the same as the IP address of the device information (2), the electronic device may also perform DLNA screen projection directly according to the IP address of the device information (1) in the DB without performing DLNA protocol search.

In another implementable manner, the device information (1) of the screen-projecting device recorded in the DB (i.e., the device information of the screen-projecting device whose electronic device system image is projected) may include an IP address, a Mac address, a uuid, and a device name, and the device information (2) of the available screen-projecting device searched by the electronic device through the DLNA protocol may include an IP address, a Mac address, a uuid, and a device name. If the electronic device searches for the screen projection device through the mirror image protocol without passing through the same wireless local area network, for example, the Miracast protocol or the Cast + protocol (which can be searched through Wifi P2P) is adopted, and the DLNA protocol searches for the available screen projection device without passing through the same wireless local area network, the IP address of the device information (1) is different from the IP address of the device information (2), and the electronic device needs to write the IP address of the device information (2) into the DB for the video APP to query. Exemplarily, if a user wants to screen a mobile phone to a television in a living room for watching a video, both the mobile phone and the television are connected to WiFi in the living room, and can search through WiFi P2P when performing mirror image screen projection, wherein an IP address of the television acquired by the mobile phone is 192.168.49.1; in the process of switching to DLNA screen projection, a DLNA protocol is required to be adopted to search for a television through a WiFi wireless network in a living room, the IP address of the television acquired by the mobile phone is 192.168.43.238 at the moment, and the two IP addresses are different.

Alternatively, the number of available screen projection devices searched by the DLNA protocol may be one or more. For example, as shown in fig. 12, the device information (1) of the screen projection device and the device information (2) of the available screen projection device may be compared to find that only uuid information in the device information (1) and the device information (2) is the same because uuid is the device unique identification code, and thus, the embodiment of the present application may perform association according to uuid. If the number of available screen projection devices searched by the DLNA protocol is one, the electronic device compares uuid of the device information (2) with uuid of the device information (1), and if the two uuids are the same, the available screen projection devices and the screen projection devices are the same device, that is, the screen projection devices that are performing mirror projection, and the electronic device can write the IP address (192.168.43.238 in fig. 9) of the device information (2) into the DB. And then the video APP can acquire the IP address from the DB, and the DLNA screen projection is carried out to the screen projection equipment corresponding to the IP address, so that the DLNA screen projection process is completed.

If the number of the available screen projection devices searched by the DLNA protocol is multiple, the electronic device takes the device which is the same as the uuid of the screen projection device for mirror image screen projection in the available screen projection devices as a target screen projection device (namely, the device is the same as the screen projection device, namely, the screen projection device for mirror image screen projection), and writes the IP address of the target screen projection device into the DB. And then the video APP can acquire the IP address of the target screen projection equipment from the DB, and the DLNA projects the screen to the screen projection equipment corresponding to the IP address, so that the process of projecting the screen to the DLNA is completed.

Optionally, after the DLNA of the electronic device is projected to the screen projection device, the video APP may further store the device information (2) in a white list. When the electronic equipment finishes mirror image screen projection next time, the video APP compares the equipment information of the screen projection equipment of the mirror image screen projection with the equipment information in the white list, and if the comparison is successful, the video APP projects the screen to the equipment corresponding to the IP address according to the IP address DLNA in the white list; and if the comparison is not successful, searching the available equipment through the DLNA protocol. Therefore, the number of DLNA searching times can be reduced, and the screen projection switching efficiency is improved.

In the implementation manner, the electronic device associates the screen projection device with the unique identification code uuid, so that the accuracy of the determined DLNA screen projection device can be improved, the screen projection device determined by the DLNA protocol is ensured to be the same as the screen projection device for mirror image screen projection, and the success rate of DLNA screen projection is improved.

In yet another implementable manner, the device information (1) of the screen-projection device recorded in the DB (i.e., the device information of the screen-projection device whose electronic device system image is projected) may include an IP address, a Mac address, a device identification, and a device name, and the device information (2) of the available screen-projection device searched by the electronic device through the DLNA protocol may include an IP address, a Mac address, a device identification, and a device name. That is to say, there is no uuid in the device information obtained in this scenario, the device identifier therein is other information for identifying the screen projection device, and the device identifier searched through the mirror image protocol may not be consistent with the device identifier searched through the DLNA protocol.

Exemplarily, as shown in fig. 13, the device information (1) of the screen projection device and the device information (2) of the available screen projection device may be found by comparison that only the device name information in the device information (1) and the device information (2) is the same, so that the embodiments of the present application may associate according to the device name. If the number of the available screen projection devices searched by the DLNA protocol is one, the electronic device compares the device name of the device information (2) with the device name of the device information (1), and if the two device names are the same, the available screen projection device and the screen projection device are the same device, that is, the screen projection device that is performing mirror image projection, and the electronic device can write the IP address (192.168.43.56 in fig. 10) of the device information (2) into the DB. And then the video APP can acquire the IP address from the DB, and the DLNA screen projection is carried out to the screen projection equipment corresponding to the IP address, so that the DLNA screen projection process is completed.

If the number of the available screen projection devices searched by the DLNA protocol is multiple, the electronic device uses a device with the same device name as the screen projection device for mirror screen projection in the available screen projection devices as a target screen projection device (i.e., the same device as the screen projection device, i.e., the screen projection device for mirror screen projection), and writes the IP address of the target screen projection device into the DB. And then the video APP can acquire the IP address of the target screen projection equipment from the DB, and the DLNA projects the screen to the screen projection equipment corresponding to the IP address, so that the DLNA screen projection process is completed. If a plurality of devices with the same device name as the screen projection device in the available screen projection devices exist, the electronic device cannot identify which device is the same as the screen projection device, and at the moment, the electronic device can output a device list of the devices through a display interface, so that a user can select the screen projection device according to own mirror image.

In the implementation manner, when the searched device information of the screen projection device does not include uuid, the electronic device may associate through the device name to adapt to the screen projection switching process of different scenes. In addition, when a plurality of searched DLNA screen projection devices exist, the DLNA screen projection devices can be selected and determined by the user, and the watching experience degree of the user is further improved.

In one scenario, when a user wants to view a locally stored video in a mirror image screen projection mode of the electronic device, the electronic device may also perform DLNA screen projection in the above manner. The local video can be played by adopting a gallery application or a player of the electronic equipment; when the "gallery" application or the player of the electronic device is playing a video and the mirror image screen projection mode is started, DLNA screen projection is performed between the electronic device and the screen projection device, and the specific screen projection process can be referred to the description of the above embodiment and is not described herein again. It should be noted that DLNA screen projection only supports fixed format audio/video data, such as image data in formats of JPEG, PNG, GIF, etc., audio data in formats of AAC, MP3, WMA, etc., video data in formats of MPEG-2, MPEG-4, AVC, WMV, etc., before screen projection switching is performed, the electronic device may also determine the format of the video data, switch to DLNA screen projection if the format of the video data meets the condition, and do not switch to the screen projection mode if the format of the video data does not meet the condition.
