DETAILED DESCRIPTION

[0017] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the embodiments of the present application should fall within the scope of protection of the embodiments of the present application.

[0018] The terms used in this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The singular forms of "a", "said" and "the" used in this application and the appended claims are also intended to include plural forms unless the context clearly indicates other meanings. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0019] It should be understood that although the terms first, second, third, etc. may be used in the present application to describe various information, these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0020] Figure 1This is a flow chart of a screen projection method according to an embodiment of the present application. Figure 1 As shown, the screen projection method includes the following steps: Step 101: Establish a connection with the projection end and obtain media information sent by the projection end.

[0021] In order to realize the control of the projection end by the display end, it is first necessary to establish a connection between the display end and the projection end. After the connection is established, the display end obtains the media information sent by the projection end. The media information is at least part of the information in the media list of the projection end. The media list is used to display the media files in the projection end. Users can set some media files in the media list to not be projected / shared, etc. by setting permissions on the projection end. At this time, the media information sent by the projection end is part of the information in the media list of the projection end. Users can improve privacy by setting permissions for some media files in the media list. In addition, encryption technology can be used for data transmission between the display end and the projection end to avoid information leakage.

[0022] Specifically, the method of establishing a connection between the display end and the projection end can be: detecting the projection end within a preset detection range, and establishing a connection with the projection end when the projection end is detected to enter the detection range, or, when the projection end is detected to enter the detection range, displaying a connection confirmation button on the display interface, and establishing a connection with the projection end in response to the confirmation instruction generated by the user triggering the connection confirmation button.

[0023] The display end can detect the projection end within a preset detection range, for example, detect whether there is a projection end within a range of 5 meters. When the projection end enters the detection range, that is, the projection end enters a circular detection range with the display end as the center and a radius of 5 meters, the projection end can automatically connect to the display end. Alternatively, when the projection end enters the detection range, a connection request can be automatically sent to the display end, and the display end displays a connection confirmation button on the display interface according to the connection request. After that, the display end responds to the confirmation instruction generated after the user triggers the connection confirmation button by clicking, long pressing, etc. to establish a connection with the projection end. When the projection end enters the detection range, the display end can also directly display the connection confirmation button on the display interface. By detecting the projection end within the preset detection range, the automatic connection between the display end and the projection end can be achieved, reducing the complexity of user operations. By displaying the connection confirmation button on the display interface, it is possible to avoid establishing a connection between the display end and the projection end when the user does not need to project the screen.

[0024] In another possible implementation method, the method of establishing a connection between the display end and the projection end can be: sending a DLNA broadcast within the detection range, and when the projection end receives the DLNA broadcast, establishing a connection with the projection end, or, when the projection end receives the DLNA broadcast, responding to the connection request sent by the projection end, displaying a connection confirmation button on the display interface, and establishing a connection with the projection end in response to the confirmation instruction generated by the user triggering the connection confirmation button.

[0025] The display end can send DLNA broadcasts within the detection range. Correspondingly, a DLNA client is installed in the projection end. After the projection end enters the detection range, it will receive the DLNA broadcast. When the projection end receives the DLNA broadcast, it automatically establishes a connection with the display end. Alternatively, when the projection end receives the DLNA broadcast, it will generate and send a connection request to the display end. The display end will display a connection confirmation button on the display interface according to the connection request. After that, the display end will respond to the confirmation instruction generated after the user triggers the connection confirmation button by clicking, long pressing, etc. to establish a connection with the projection end. By sending DLNA broadcasts, the efficiency of the connection between the projection end and the display end can be improved, and DLNA broadcasts are easy to configure, and can prevent other projection ends from being connected incorrectly through personalized configuration.

[0026] Step 102: Display media information on the display interface.

[0027] When the display terminal acquires the media information, the media information is displayed on a display interface included in the display terminal. The user can see the specific media information through the display interface.

[0028] Step 103: In response to the control instruction generated by the control component in the user-triggered display interface, a control request is sent to the projection end, so that the projection end responds to the control request and plays the corresponding media file.

[0029] While displaying media information on the display interface, a certain number of control components will also be displayed. The control components may include components with control functions such as play, pause, double speed, triple speed, fast forward, and fast rewind. Users can trigger the control components in the display interface by clicking, long pressing, etc., and corresponding control instructions can be generated. After that, the display end sends a control request to the projection end in response to the generated control instruction. After receiving the control request, the projection end plays the corresponding media file according to the control request.

[0030] In an embodiment of the present application, by sending a control request from the display end to the projection end, the user can realize reverse control of the projection end through the display end. In addition, the display end displays media information through a display interface, which enables the user to directly operate at least part of the information in the media list of the projection end, thereby reducing the difficulty of user operation.

[0031] Figure 2is a schematic diagram of a screen projection scenario applicable to this application, such as Figure 2 As shown, the projection end can be a mobile communication device such as a mobile phone, and the display end can be a display device in a vehicle, which can include components or devices such as a media player.

[0032] The mobile phone and the display device can be installed with a DLNA client and a DLNA server respectively. The display device can send broadcasts in the local area network, such as through WiFi or AP. When the mobile phone is connected to the local area network and receives the broadcast, the mobile phone notifies the display device of its existence through the DLNA protocol. When the display device receives the notification from the mobile phone, it can automatically connect, or a pop-up box can be displayed on the display interface to ask the user to confirm the connection to the mobile phone. After the user triggers the connection confirmation button, the display device establishes a connection with the mobile phone according to the generated confirmation instruction.

[0033] After the mobile phone establishes a connection with the display device, the screen projection method may also include: when the projection end plays the corresponding media file, in response to the user triggering the configuration instruction generated by the configuration component in the display interface, the first parameter of the atmosphere equipment in the vehicle and the second parameter of the projection end are configured, and the corresponding configuration information is stored in the projection end.

[0034] When playing a media file, the user can simultaneously configure the first parameter of the atmosphere device in the vehicle and the second parameter of the projection end. The atmosphere device in the vehicle may include air conditioners, seats, atmosphere lights, roof lights and other equipment. Correspondingly, the first parameter may include air conditioner wind speed, air conditioner temperature, air conditioner wind direction, seat angle, atmosphere light brightness, atmosphere light color, roof light brightness, roof light color and other parameters. The second parameter may be a mobile phone volume, mobile phone sound effect and other parameters. The user can personalize at least part of the above parameters when playing a media file. The specific configuration method may be to trigger the configuration component in the display interface to generate the corresponding configuration instruction. The display device may configure the first parameter of the atmosphere device in the vehicle through the configuration instruction, or may configure the second parameter of the mobile phone through the configuration instruction, and send it to the mobile phone. After the mobile phone receives the second parameter, it will be configured according to the second parameter. After the user configuration is completed, the corresponding configuration information can be sent to the mobile phone so that the mobile phone stores the corresponding configuration information. The user can configure the projection end and the display end accordingly by triggering the configuration component in the display interface, which can support user personalization while reducing the complexity of user operations.

[0035] Specifically, after the mobile phone establishes a connection with the display device, the configuration information stored in the projection end can be obtained. If the configuration information is obtained, the first playback parameter of the projection end is changed according to the configuration information to obtain the second playback parameter, so that the projection end plays the corresponding media file according to the second playback parameter.

[0036] Since the mobile phone can store the configuration information that the user configured for the corresponding device when playing the media file last time, the next time the mobile phone establishes a connection with the display device, the configuration information stored in the mobile phone can be directly obtained and directly applied to change the default first playback parameter to obtain the second playback parameter. Since the first playback parameter includes the first parameter of the atmosphere device in the vehicle and the second parameter of the projection end, the changed second playback parameter also includes the first parameter of the atmosphere device in the vehicle and the second parameter of the projection end. Therefore, the mobile phone can play the corresponding media file according to the second playback parameter, or the display device can also adjust the parameters of the atmosphere device in the vehicle according to the second playback parameter and play the corresponding media file. By obtaining the configuration information stored in the projection end after the projection end and the display end are connected, the configuration information can be directly applied, thereby reducing the user's operations and improving the user's experience.

[0037] In one possible implementation, media files can be played not only through a mobile phone but also through a media player in a display device, and the user can switch the playback mode by triggering a corresponding mode switching button on the display panel.

[0038] Figure 3 This is a flow chart of a screen projection method according to another embodiment of the present application. Figure 3 As shown, the screen projection method applied to the screen projection end includes the following steps: Step 301: Send media information to a display terminal.

[0039] The media information is at least part of the information in the media list, and the media list is used to display the media files in the projection end.

[0040] Step 302: Receive a control request sent by the display terminal, and play a corresponding media file in response to the control request.

[0041] After the projection end sends the media information to the display end, it waits for the display end to send a control request. After receiving the control request sent by the display end, it responds to the control request to play the corresponding media file.

[0042] It should be noted that media files can be played through the built-in audio device of the projection end, or through the audio device controlled by the display end.

[0043] Specifically, the process of sending the media information to the display end may further include: adding permissions to at least some of the media files in the media list, generating media information according to the media files to which permissions are not added, and sending the media information to the display end.

[0044] Users can set permissions on the projection end to set some media files in the media list to not be projected / shared, etc., and generate media information based on the media files that have not been added with permissions. At this time, the media information sent by the projection end is part of the information in the media list of the projection end. Users can improve privacy by setting permissions for some media files in the media list. In addition, encryption technology can be used for data transmission between the display end and the projection end to avoid information leakage.

[0045] In an embodiment of the present application, by sending a control request from the display end to the projection end, the user can realize reverse control of the projection end through the display end. In addition, the display end displays media information through a display interface, which enables the user to directly operate at least part of the information in the media list of the projection end, thereby reducing the difficulty of user operation.
