Currently, many electronic devices support a wireless screen-throwing technology, that is, a display interface of an electronic device a (e.g., a mobile phone or a tablet) is displayed on a screen of another device B (e.g., a computer, a television, an all-in-one machine or a projector) in "real time", so that a user can watch the content of a screen through the device B.

When a user needs to use the wireless screen-throwing function of the electronic device, the user usually clicks a wireless screen-throwing button in a system pull-down menu of the electronic device, and then selects screen-throwing equipment from an available equipment list searched by the electronic device, so that the wireless screen throwing of the electronic device can be completed. At this time, the electronic device realizes a system mirror image screen projection (hereinafter referred to as mirror image screen projection for short), that is, what interface is displayed on the electronic device, and what interface is also displayed on the screen projection device.

However, in the process of system mirror image screen projection, if the electronic device currently plays video, the video interface of the screen projection device is easy to have problems of blocking, screen pattern, black edge, asynchronous audio and video, and the like, so that the screen projection effect is poor.

Disclosure of Invention

The application provides a screen projection method of electronic equipment and the electronic equipment, which can automatically switch the mirror image screen projection between the screen projection equipment into the screen projection of a digital living network alliance (digital living network alllance, DLNA) when the electronic equipment plays videos, and effectively improve the screen projection effect.

In a first aspect, the present application provides a method for projecting a screen of an electronic device, where the method includes: receiving a user screen-throwing operation, and throwing the electronic equipment to the screen-throwing equipment in a system mirror image screen-throwing mode; receiving video playing operation of the electronic equipment, and acquiring screen throwing information of the electronic equipment, wherein the screen throwing information comprises first equipment information of the screen throwing equipment, and the first equipment information comprises at least one of an internet protocol address (internet protocol address, IP address), a media access control address (media access control address, mac address), a universal unique identification code (universally unique identifier, uuid), an equipment identifier and an equipment name of the screen throwing equipment; and switching the screen-throwing mode between the electronic equipment and the screen-throwing equipment from the system mirror image screen-throwing mode to the DLNA screen-throwing mode according to the first equipment information.

The system mirror image screen projection process is that the electronic equipment encodes and decodes the data of the display interface and then sends the data to the screen projection equipment for display, and if the electronic equipment currently plays video, the video stream is encoded and decoded and then sent to the screen projection equipment for playing. The DLNA screen-casting is a technology for serving digital media and content, and the electronic device can send an address of a video stream to the screen-casting device, and the screen-casting device downloads video resources according to the address to play, so that real-time screen-casting of video data is realized. When the electronic equipment plays videos, if the electronic equipment is in a system mirror image screen-throwing state, the electronic equipment can be automatically switched to DLNA screen throwing, so that the problems of black edges, blocking, screen-printing, asynchronous sound and picture and the like of pictures are reduced, the played video pictures are clear and smooth, the screen-throwing effect is effectively improved, other operations are not needed by a user, and the watching experience of the user is also improved.

Optionally, the video played by the electronic device may be played online by a video application, or may be played locally by a video player.

Before the electronic equipment switches the screen-throwing mode, the stored equipment information of the screen-throwing equipment is required to be acquired, and then the DLNA of the electronic equipment is thrown to the screen-throwing equipment according to the first equipment information (such as an IP address). Optionally, the implementation manner may be applicable to a case where the electronic device and the screen-throwing device are in the same local area network, where the IP address of the screen-throwing device searched through the mirror image protocol is the same as the IP address of the screen-throwing device searched through the DLNA protocol.

With reference to the first aspect, in some implementations of the first aspect, according to the first device information, switching a screen-throwing mode between the electronic device and the screen-throwing device from a system image screen-throwing mode to a DLNA screen-throwing mode includes: searching first available screen-throwing equipment through a DLNA protocol, and acquiring second equipment information of the first available screen-throwing equipment, wherein the first available screen-throwing equipment is equipment which is located in the same local area network with the electronic equipment and supports DLNA screen throwing, and the second equipment information comprises at least one of an IP address, a Mac address, a uuid, an equipment identifier and an equipment name of the first available screen-throwing equipment; and matching the first equipment information with the second equipment information, and if the first equipment information is successfully matched with the second equipment information, projecting the screen of the electronic equipment to the screen projecting equipment in a DLNA screen projecting mode.

Because some mirror image protocol searching and screen-throwing devices do not need to pass through a local area network, such as a Miracast protocol, for the same device, the IP address searched through the mirror image protocol is different from the IP address searched through the DLNA protocol, and therefore the first device information and the second device information need to be matched, if the matching is successful, the fact that the first device information and the second device information are the same device is indicated, and then the electronic device DLNA is screened to the screen-throwing device. Therefore, the success rate of switching the electronic equipment into DLNA screen throwing can be further improved.

When the electronic equipment only searches one screen throwing device, the screen throwing device can directly throw the mirror image of the display interface; when a plurality of screen throwing devices are searched, the available device list can be displayed to a user for the user to select the corresponding device, and data of the display interface are sent to the screen throwing devices for display. And then the electronic equipment can record the equipment information of the screen-throwing equipment after the screen throwing of the system mirror image, and can be used for carrying out information matching when the screen throwing of the DLNA is carried out later so as to improve the success rate of switching to the screen throwing of the DLNA.

With reference to the first aspect, in some implementations of the first aspect, the video is played by a video application installed in the electronic device. When a user watches videos through video application, if a screen-throwing mode between the electronic equipment and the screen-throwing equipment is automatically switched from a system mirror image screen-throwing mode to a DLNA screen-throwing mode, the screen-throwing effect can be improved, and meanwhile the experience degree of watching the videos of the user is improved.

For easy understanding, the following embodiments of the present application will take an electronic device having a structure shown in fig. 4 and fig. 5 as an example, and the screen projection method of the electronic device provided in the embodiments of the present application will be specifically described 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 the process flow of the embodiment of the present application is described below with reference to fig. 6.

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

When the wireless screen-throwing module searches the screen-throwing equipment through the mirror image protocol, the corresponding mirror image protocol can be selected preferentially according to the capability of the equipment supporting screen throwing at present, and the mirror image protocols which are popular at present comprise Miracast protocol, cast+ protocol, airPlay protocol, lelink protocol and the like.

Specifically, miracast is a wireless display standard established by Wi-Fi alliance in 2012, and is based on Wi-Fi Direct (Wi-Fi Direct), a device that uses Miracast protocol to perform wireless screen-casting does not need to access to a wireless local area network, and an electronic device can directly play a video or a photo on the screen-casting device through the protocol without any connection line or wireless hotspot (AP); in the Miracast application scene, a smart phone supporting P2P can be directly connected with a smart television supporting P2P, and the smart phone can transmit a screen or media resource of the smart phone to the smart television for display or play. The cast+ protocol can support the electronic equipment of a fixed brand A to carry out wireless screen casting, and the packet loss rate is low in the audio and video data transmission process. The AirPlay protocol is a wifi-based wireless display standard, can be applied between electronic equipment of a fixed brand B and screen throwing equipment, and supports a push mode and a mirror mode. The equipment adopting the leink protocol for wireless screen-casting needs to be accessed into the same wireless local area network.

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

First, while the third party video APP is playing the video, the user clicks the "wireless screen" button in fig. 1 (b) or fig. 2 (a) (or finds the "wireless screen" button through the "setup" path of the electronic device). Then if the wireless screen-throwing module of the service layer monitors that the video APP is playing the video, the screen-throwing device search can be performed through a mirror image protocol provided by the screen-throwing capability center, for example, through Miracast protocol search, at the moment, the screen-throwing capability center opens a P2P or WALN connection channel, and establishes a channel with WiFi P2P screen-throwing equipment or establishes a channel with WiFi (STA) screen-throwing equipment through a WifiP2PManager manager. In one implementation, as shown in fig. 7 (a), after the channel is established, the screen throwing capability center does not push a data stream to the display manager DisplayManager, but the multi-screen interaction framework writes the status identifier of the opened mirror screen throwing into the configuration file settingand the device information of the connected screen throwing device into the DB. And then, if the third-party video APP monitors that the electronic equipment is started to switch on the mirror image, calling a DLNA interface in the system to switch on the DLNA.

In another implementation, as shown in fig. 7 (b), after the channel is established, the screen throwing capability center pushes the data stream to the DisplayManager, but the DisplayManager filters out the data stream, i.e. does not display it on the screen throwing device. Then the multi-screen interactive framework writes the status identification of the opened mirror image screen into the configuration file Settings and writes the equipment information of the screen-throwing equipment for establishing connection into the DB. If the third-party video APP monitors that the electronic equipment has started the mirror image screen projection, a DLNA interface in the system is called to perform DLNA screen projection.

In summary, because the screen projection device has the above-mentioned problems such as black edges of the screen when the mirror image screen projection is performed, after the mirror image screen projection function is started, the video APP can call the internal DLNA interface, and the video APP can automatically turn into the DLNA screen projection. When the electronic equipment DLNA is used for screen projection, the address (such as a uniform resource positioning system (uniform resource locator, URL)) of the played audio and video data can be pushed to the screen projection equipment, so that the screen projection equipment can download data resources according to the address of the audio and video data, and further full-screen playing is realized, the problems of black edges, blocking, screen display, asynchronous audio and video pictures and the like can be reduced, the played video pictures are clear and smooth, the screen projection effect is effectively improved, other operations are not required by a user, and the experience of the user is also improved. In addition, by adopting the DLNA screen-throwing mode, a user can execute other operations on the electronic equipment without influencing the normal playing of the video of the screen-throwing equipment.

First, introducing the implementation process of the scenario in fig. 1, that is, the scenario in which the electronic device plays the video first and then opens the mirror image screen, in combination with the system architecture shown in fig. 6, fig. 8 is a flowchart of an example of a screen projection method of the electronic device, 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-throwing state, the state identifier may be 1, and when the electronic device is not in the mirror image screen-throwing state, the state identifier may be 0.

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

Specifically, when the electronic device is not in the mirror image screen-throwing state (i.e., the state identifier is 0), if the video APP in the electronic device starts to play the video, the screen throwing cannot be performed on the screen-throwing device, and at this time, a mirror image screen-throwing function (i.e., screen throwing operation) is required to be opened by the user.

After a user opens the mirror image screen-throwing function, the electronic equipment can search the equipment through a mirror image protocol, and when the electronic equipment searches only one screen-throwing equipment, the mirror image screen-throwing of the display interface can be directly carried out on the screen-throwing equipment. When the electronic device searches for a plurality of screen-throwing devices, the list of available devices can be displayed to the user, such as the display interface shown in the (c) diagram in fig. 1, and then after receiving the selection operation of the user, the electronic device mirrors the display interface to the screen-throwing device selected by the user. When the screen throwing device searched by the electronic device is the screen throwing device selected by the user before, the screen throwing device can also directly throw the mirror image screen of the display interface. It can be understood that after the display interface of the electronic device mirrors the screen to the screen-throwing device, the electronic device can record the status identifier of the opened mirror screen-throwing device and the device information of the screen-throwing device for establishing connection.

S203, acquiring first equipment information of the screen-throwing equipment, and switching a screen-throwing mode between the electronic equipment and the screen-throwing equipment from mirror image screen-throwing to DLNA screen-throwing according to the first equipment information.

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

For this procedure, the manner in which the electronic device starts the mirror image screen projection mode to watch the video is known, in which the electronic device plays the video first and then starts the mirror image screen projection, and for this procedure, the procedure of switching to the DLNA screen projection is described as follows: referring to fig. 9 (a), in the process of playing video, if the current electronic device does not start the mirror image screen-throwing function, the video APP will start the monitor module ContentObserver to monitor the data in the Settings (i.e. when the video APP plays video, it will monitor whether the electronic device is in the mirror image screen-throwing state). When the state identification in the Settings is monitored to be that the mirror image screen projection is started, namely the electronic equipment is subjected to mirror image screen projection to the screen projection equipment, and the video APP plays the video at the moment, the video APP acquires the equipment information of the connected screen projection equipment from the DB, and the screen projection mode between the electronic equipment and the screen projection equipment is switched from mirror image screen projection to DLNA screen projection. In addition, the ContentObserver can also monitor whether the mirror image screen is disconnected between the electronic equipment and the screen-throwing equipment, for example, after the electronic equipment disconnects the mirror image screen-throwing, the video APP monitors the disconnection message and calls the internal DLNA interface to disconnect the DLNA screen-throwing.

According to the screen projection method of the electronic equipment, when the electronic equipment plays videos, if the electronic equipment is not in the state of system mirror image screen projection currently, the electronic equipment can receive the operation that a user starts a system mirror image screen projection function and switch the mirror image screen projection into DLNA screen projection, so that the problems of black edges, blocking, screen pattern, asynchronous sound and picture and the like of pictures are reduced, the played video pictures are clear and smooth, the screen projection effect is effectively improved, other operations are not needed by the user, and the viewing experience of the user is also improved.

For the scenario in fig. 1, the implementation may also be combined with the system architecture shown in fig. 7, and fig. 10 is a flowchart of another method for projecting a screen of an electronic device according to an 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, which is not described herein.

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

Specifically, when the electronic device is not in the mirror image screen-throwing state, if the video APP in the electronic device starts playing the video, the screen throwing cannot be performed on the screen-throwing device, and at this time, a user needs to open a mirror image screen-throwing function (i.e., screen throwing operation).

After the user opens the mirror image screen-throwing function, the electronic equipment can search the equipment through the mirror image protocol, and after the screen-throwing equipment is searched, the channel connection between the electronic equipment and the screen-throwing equipment is established. In one implementation, the electronic device establishes only a channel connection with the screen throwing device, and does not push a data stream to the screen throwing device; in another implementation, the electronic device establishes a channel connection with the screen-casting device and pushes a data stream to the screen-casting device, but the screen-casting device filters the data stream. That is, in this implementation, the screen-casting device does not display an interface of the electronic device that mirrors the screen-casting.

It can be understood that after the electronic device establishes the channel connection with the screen-throwing device, the status identifier of the opened mirror image screen-throwing device and the device information of the connected screen-throwing device can also be recorded.

S303, acquiring first equipment information of the screen-throwing equipment, and throwing the screen of the electronic equipment to the screen-throwing equipment in a DLNA screen-throwing mode according to the first equipment information.

Specifically, the video APP can monitor whether the electronic device is in a mirror image screen-throwing state, acquire device information of the screen-throwing device when the opened mirror image screen-throwing is monitored, and call the internal DLNA interface, so that the electronic device does not mirror image screen-throwing to the screen-throwing device, and then the electronic device can be directly screen-throwing to the screen-throwing device in a mode of throwing the DLNA screen, that is, at the moment, there is no mirror image screen-throwing to the DLNA screen-throwing switching process in the sense of a user.

According to the screen projection method of the electronic equipment, when the electronic equipment plays videos, if the electronic equipment is not in the state of system mirror image screen projection currently, the electronic equipment can receive the operation of starting the system mirror image screen projection function by a user and directly projects the screen to the screen projection equipment in a DLNA screen projection mode, so that the problems of black edges, blocking, screen patterns, asynchronous sound and picture and the like of pictures are reduced, the played video pictures are clear and smooth, the screen projection effect is effectively improved, other operations are not needed by the user, and the watching experience of the user is also improved.

Next, introducing the implementation process of the scenario in fig. 2, that is, the scenario in which the electronic device opens the mirror image to throw the screen and then plays the video, in combination with the system architecture shown in fig. 6, fig. 11 is a flowchart of another embodiment of a method for throwing the screen of the electronic device, where the method includes:

s401, receiving a user screen-throwing operation, and throwing the electronic equipment to the screen-throwing equipment in a mirror image screen-throwing mode.

The screen-throwing operation may be a clicking operation of the "wireless screen-throwing" button in the diagram (a) in fig. 2, or a clicking operation of the "wireless screen-throwing" button in the "setting" path of the electronic device. The mirror image screen projection process in this step may be referred to the description of the above embodiments, and will not be repeated here.

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

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

Specifically, after the electronic equipment is subjected to mirror image screen projection to the screen projection equipment, current screen projection information can be stored, if a video APP installed in the electronic equipment is playing video, the video APP actively acquires the screen projection information, and when the electronic equipment is in a mirror image screen projection state, the video APP calls an internal DLNA interface, so that a screen projection mode between the electronic equipment and the screen projection equipment is switched from mirror image screen projection to DLNA screen projection.

For this procedure, the manner in which the electronic device starts the mirror image screen projection mode to watch the video is known, and for this procedure, the procedure of switching to the DLNA screen projection mode is described below: referring to the diagram (b) in fig. 9, the electronic device is already in the mirror screen-casting mode, when the user clicks the video APP to play the video, the video APP calls the system interface to acquire data in Settings and DB, if the status in Settings is identified as that the mirror screen-casting is started and there is device information of the connected screen-casting device in DB, the screen-casting mode between the electronic device and the screen-casting device is switched from the mirror screen-casting mode to the DLNA screen-casting mode. This approach differs from the approach described above with respect to fig. 9 (a) in that it does not require the monitor module ContentObserver to be started to actively monitor the state of the system image screen.

According to the screen projection method of the electronic equipment, when the electronic equipment plays videos, if the electronic equipment is in the state of system mirror image screen projection, the electronic equipment can be automatically switched to DLNA screen projection, so that the problems of black edges, blocking, screen pattern, asynchronous audio and video and the like of pictures are reduced, the played video pictures are clear and smooth, the screen projection effect is effectively improved, other operations are not needed by a user, and the viewing experience of the user is also improved.

In an actual scene, when the DLNA screen is adopted to screen the electronic equipment to the screen-throwing equipment, the screen-throwing equipment determined by the electronic equipment through the DLNA protocol and the screen-throwing equipment (or the screen-throwing equipment of the mirrored screen-throwing equipment) which establishes connection are required to be ensured to be identical, and then the electronic equipment can be successfully switched to the DLNA screen-throwing equipment. As can be seen from the above description, after the electronic device establishes a connection with the screen-throwing device, device information of the screen-throwing device may be recorded in the DB, including 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 available screen-throwing devices supporting DLNA screen-throwing through a DLNA protocol, obtain device information of the available screen-throwing devices supporting DLNA screen-throwing, compare the device information of the available screen-throwing devices supporting DLNA screen-throwing with the device information in the DB, and if the comparison is successful, switch the mirror image screen-throwing to DLNA screen-throwing.

In one implementation manner, the device information (1) of the screen-throwing device (i.e., the device information of the screen-throwing device of the electronic device system mirror image screen-throwing device) recorded in the DB includes an IP address, and the device information (2) of the available screen-throwing device searched by the electronic device through the DLNA protocol also includes the IP address. If the electronic device searches for the screen-throwing device through the mirror image protocol, for example, the leink protocol is adopted, and the available screen-throwing device is searched through the DLNA protocol, and the obtained IP address of the device information (1) is the same as the IP address of the device information (2), then the video APP in the electronic device can directly obtain the IP address of the device information (1) from the DB, and the DLNA throws a screen to the screen-throwing device corresponding to the IP address, thereby completing the DLNA screen-throwing process. Optionally, in this implementation manner, since the IP address of the device information (1) and the IP address of the device information (2) are the same, the electronic device may perform DLNA screen-casting directly according to the IP address of the device information (1) in the DB without performing DLNA protocol search.

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

Alternatively, the number of available screen-casting 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-throwing device and the device information (2) of the available screen-throwing device may find through comparison that, because uuid is a device unique identification code, only uuid information in the device information (1) and the device information (2) is the same, and thus the embodiments of the present application may perform association according to uuid. If the number of available screen-throwing devices searched by the DLNA protocol is one, the electronic device compares the uuid of the device information (2) with the uuid of the device information (1), if the two uuids are the same, the available screen-throwing device and the screen-throwing device are the same device, that is, the screen-throwing device which is mirroring the screen-throwing device, and the electronic device can write the IP address (such as 192.168.43.238 in fig. 9) of the device information (2) into the DB. Then the video APP can acquire the IP address from the DB, and the DLNA screen is projected to the screen projection equipment corresponding to the IP address, so that the process of DLNA screen projection is completed.

If the number of the available screen throwing devices searched through the DLNA protocol is multiple, the electronic device takes the device which is the same as the uuid of the screen throwing device of the mirror image screen throwing device in the available screen throwing devices as the target screen throwing device (namely, the device which is the same device as the screen throwing device, namely, the screen throwing device which is the mirror image screen throwing device), and writes the IP address of the target screen throwing device into the DB. Then, the video APP can acquire the IP address of the target screen-throwing device from the DB, and the DLNA screen-throwing device corresponding to the IP address is thrown to finish the process of throwing the DLNA screen.

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

In the implementation manner, the electronic equipment performs association of the screen-throwing equipment through the unique identification code uuid, so that the accuracy of the determined DLNA screen-throwing equipment can be improved, the screen-throwing equipment determined through the DLNA protocol and the screen-throwing equipment of the mirror image screen-throwing equipment are ensured to be the same, and the success rate of the DLNA screen-throwing is improved.

In still another possible manner, the device information (1) of the screen-throwing device (i.e., the device information of the screen-throwing device of the electronic device system mirror image screen-throwing) recorded in the DB may include an IP address, a Mac address, a device identification, and a device name, and the device information (2) of the available screen-throwing 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, there is no uuid in the device information obtained in this scenario, where the device identifier is other information for identifying the screen-throwing device, and the device identifier searched through the mirror protocol may not be consistent with the device identifier searched through the DLNA protocol.

For example, as shown in fig. 13, the device information (1) of the screen-throwing device and the device information (2) of the available screen-throwing device may find that only the device name information in the device information (1) and the device information (2) is the same through comparison, so that the embodiments of the present application may perform association according to the device name. If the number of available screen-throwing 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), if the two device names are the same, the available screen-throwing device and the screen-throwing device are the same device, that is, the screen-throwing device which is in mirror image screen-throwing, and the electronic device can write the IP address (such as 192.168.43.56 in fig. 10) of the device information (2) into the DB. Then the video APP can acquire the IP address from the DB, and the DLNA screen is projected to the screen projection equipment corresponding to the IP address, so that the process of DLNA screen projection is completed.

If the number of the available screen throwing devices searched through the DLNA protocol is a plurality of, the electronic device takes the device with the same device name as the screen throwing device of the mirror image screen throwing device in the available screen throwing devices as the target screen throwing device (namely, the device with the same device as the screen throwing device, namely, the screen throwing device which is the mirror image screen throwing device), and writes the IP address of the target screen throwing device into the DB. Then the video APP can acquire the IP address of the target screen-throwing device from the DB, and the DLNA screen-throwing device corresponding to the IP address is thrown to complete the DLNA screen-throwing process. If a plurality of devices with the same device name as the screen throwing device are available in the screen throwing devices, the electronic device cannot identify which device is the same device as the screen throwing device, and at the moment, the electronic device can output a device list of the devices through a display interface so as to allow a user to select according to the mirror image screen throwing device.

In the above implementation manner, when the searched device information of the screen-throwing device does not include uuid, the electronic device may associate with the device name to adapt to the screen-throwing switching process of different scenes. In addition, when the number of the searched DLNA screen-throwing devices is multiple, the user can select and determine the DLNA screen-throwing devices, so that the viewing experience of the user is further improved.

In one scenario, when a user wants to view a locally stored video using a mirrored screen-casting mode of the electronic device, the electronic device may also perform DLNA screen casting in the manner described above. The local video can be played by a 'gallery' application, and can also be played by a player carried by the electronic equipment; when the electronic device "gallery" application or the player is playing the 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 described in the above embodiments, which are not repeated here. It should be noted that, the DLNA screen only supports audio and video data in a fixed format, such as image data in a format of JPEG, PNG, GIF, audio data in a format of AAC, MP3, WMA, etc., and video data in a format of MPEG-2, MPEG-4, AVC, WMV, etc., and the electronic device may determine the format of the video data before the screen switching, and if the format of the video data meets the condition, the video data is switched to the DLNA screen, and if not, the screen switching mode is not switched.
