The terminal receives a response message sent by the server; acquiring target content meeting the display mode according to the response message; the target content is then transmitted to a display device for display. The display device receives the target content and displays the target content based on the display mode.
In this embodiment, when the user triggers the screen projection, a content request message may be sent to the server to request the target content meeting the display mode, where the display mode is used to indicate that the display device is a horizontal screen display or a vertical screen display; the server returns a response message to the terminal, decodes the response message and can obtain target content; then, sending target content to the display equipment, wherein the target content is suitable for the display mode of the display equipment, so that stretching or cutting of the content is not needed, and a non-screen-throwing display area does not exist during display; therefore, the scheme can promote user experience.
The following will describe in detail. The numbers of the following examples are not intended to limit the preferred order of the examples.
In this embodiment, a screen projection method is provided, as shown in fig. 1b, and a specific flow of the screen projection method may be as follows:
110. responding to the screen throwing triggering operation, generating a content request message, wherein the content request message is used for requesting target content from a server, and the content request message comprises the identification of the target content and the identification of a corresponding display mode; the display mode is a vertical screen display mode or a horizontal screen display mode.
The screen-throwing triggering operation can trigger a screen-throwing function, and the screen-throwing function can be realized based on a DLNA/miracast/air screen-throwing protocol/music playing screen-throwing mode and the like. In some embodiments, the content request message may be generated in response to a screen shot trigger operation to a screen shot region. The screen throwing area can be part or all of the area on the display interface of the terminal, the screen throwing area can comprise a screen throwing control which is used for packaging corresponding data and methods of the screen throwing function and can be a control in the forms of an input box, a button, a radio selection box, a check box and the like; for example, the screen-throwing area may be displayed on a user interface of an application program installed on the terminal, and after the screen throwing is triggered, the screen throwing may be performed on the content in the application software, and if the application program is video software, the screen throwing may be performed on the video content in the video software. The screen triggering operation can be operations such as clicking, double clicking, sliding, dragging and the like. For example, the terminal may display a screen-drop region on the display interface, the user may click on the open screen-drop control, and the terminal generates content request information in response to a click operation on the open screen-drop control. In some embodiments, the screen-cast trigger operation may be triggering a screen-cast function between the terminal and the display device by near field communication (Near Field Communication, NFC).
The target content can be various multimedia information such as video, album, audio and the like, and can also be a real-time operation picture for operating the application software on the terminal. The identification of the target content may be a unique identification of the target content for distinguishing other content.
The vertical screen display mode is used for indicating that the display device is suitable for displaying the picture content of the vertical screen, and the horizontal screen display mode is used for indicating that the display device is suitable for displaying the horizontal screen picture content. For example, the display mode may be set to 11, 01, and 10, where 11 indicates that the display mode is a portrait display mode and a landscape display mode, that is, indicates that the display device is suitable for displaying both the screen content of the landscape screen and the screen content of the portrait screen; 10 indicates that the display mode is a portrait display mode, i.e. the display device is only suitable for displaying the picture content of a portrait screen, and 01 indicates that the display mode is a landscape display mode, i.e. the display device is only suitable for displaying the picture content of a landscape screen.
In some embodiments, the content request information may include an identification of the target content and an identification of the corresponding display mode, and may further include an address of the terminal, and an address of the server. Wherein, the display mode can be determined according to the screen resolution or the display proportion, and the screen resolution and the display proportion are display parameters corresponding to the display equipment; or, receiving a display mode sent by the display device, determining the display mode by the display device based on the screen resolution or the display proportion of the display device, and sending the display mode to the terminal after establishing connection with the terminal.
In some embodiments, in response to a screen-shot triggering operation on the screen-shot region, the terminal may also establish a connection with the display device; the display device may broadcast display parameters, and the terminal receives the display parameters sent by the display device, where the display parameters include at least one of the following: screen resolution, display scale, refresh rate. The terminal may then generate the content request information based on the display parameters, i.e. the content request information further includes the display parameters.
In some embodiments, the content request message further includes a target screen-throwing mode, and the terminal may obtain the target screen-throwing mode in response to a selection operation of the screen-throwing mode. Optionally, before generating the content request message, the terminal may display a selection area of the screen-casting mode after the user clicks the screen-casting area; for example, the selection area may include a button corresponding to a single screen display and a button corresponding to a multi-screen display, and the screen-casting mode includes the single screen display and the multi-screen display. And the terminal responds to the selection operation of the selection area to obtain a target screen projection mode. For example, if the user clicks a button corresponding to the single-screen display, the target screen-throwing mode is obtained as the single-screen display; and the user clicks a button corresponding to the multi-screen display, so that the target screen-throwing mode is obtained to be the multi-screen display. Thus, the content request message also includes a target screen-drop mode to obtain the appropriate target content for each device.
When the target screen-throwing mode is multi-screen display, the content request message also comprises a first object identifier and a second object identifier. The first object identifier and the second object identifier are the ID values of the parameter target objects in the content request message; the first object identifier corresponds to the terminal, the second object identifier corresponds to the display device, and the second object identifier is a projector assuming that the first object identifier is STA. The content request message includes the first object identifier and the second object identifier, which indicates that the server is required to return the first target content adapted to be displayed on the terminal and the second target content adapted to be displayed on the display device. It should be noted that, when the target screen-throwing mode is multi-screen display, the content request message may also include a plurality of object identifiers, that is, the terminal may throw the screen onto a plurality of display devices.
When the target screen-throwing mode is single-screen display, the content request message also comprises a second object identification, namely the server is only required to return target content suitable for being displayed on the display device.
In some embodiments, when the display mode of the display device is a flat screen display mode, the terminal responds to the screen throwing trigger operation, and can also determine whether the display mode of the currently displayed target content is the flat screen display mode; when the display mode is a horizontal screen display mode, the terminal can directly encode the content and then transmit the content to the display equipment for display; when the display mode is not the horizontal screen display mode, a content request message is generated, and at this time, the identifier of the display mode carried in the content request message may be set to 01.
120. And sending a content request message to the server, and receiving a response message of the server.
In some embodiments, the terminal sends a content request message to the server according to the address of the server; the server receives the content request message sent by the terminal and generates a response message based on the content request message. The server can store target content suitable for vertical screen display and target content suitable for horizontal screen display, the target content suitable for vertical screen display can also be suitable for various screen resolutions or display proportions, and the target content suitable for horizontal screen display can also be suitable for various screen resolutions or display proportions. The server may acquire the target content based on the identification of the target content and the identification of the display mode; or, acquiring the target content based on the display parameter, the identification of the target content and the identification of the display mode; or, acquiring the target content based on the screen throwing mode, the ID of the target object, the display parameter, the identification of the target content and the identification of the display mode. And then the target content can be encoded to generate a response message; it should be noted that the response message may be an information stream. And the server sends a response message to the terminal according to the address of the terminal, and the terminal receives the response message sent by the server.
130. And acquiring target content meeting the display mode according to the response message.
140. And transmitting the target content to a display device for display.
In some embodiments, the content request message includes an address of the terminal, an address of the server, an identification of the target content, and an identification of the corresponding display mode; for example, when the display mode is a horizontal screen display mode, the terminal decodes the response message to obtain the target content suitable for horizontal screen display, the terminal can encode the target content and then transmit the encoded target content to the display device, the display device receives the encoded target content and decodes the encoded target content to obtain the target content, and then the target content is displayed according to the display mode. According to different display modes of different display devices, corresponding content is acquired, and interaction between the terminal and the display devices can be facilitated.
In some embodiments, the content request message includes the display parameter, the address of the terminal, the address of the server, the identifier of the target content, and the identifier of the corresponding display mode, so that the response message is decoded to obtain the target content meeting the display mode and the display parameter, then the terminal can encode the target content and transmit the encoded target content to the display device, and the display device receives the encoded target content and decodes the encoded target content to obtain the target content, and then displays the target content according to the display mode. For example, if the display parameter is a display ratio, set to 16:9, and the display mode is set to 01, the obtained target content is suitable for being displayed on a horizontal screen on a display device with the display ratio of 16:9.
In some embodiments, the content request message includes a target screen-drop mode, an ID of the target object, a display parameter, an address of the terminal, an address of the server, an identification of the target content, and an identification of the corresponding display mode.
When the target screen-throwing mode is multi-screen display, the content request message comprises a first object identifier and a second object identifier. Therefore, decoding the response message to obtain the first target content and the second target content meeting the display mode; the first target content is marked by a first object mark, and the second target content is marked by a second object mark; the specific content data in the first target content and the second target content are the same, but the corresponding display modes, resolutions, display proportions, and the like may be different; the first target content is target content adapted for display on the terminal, and the second target content is target content adapted for display on the display device.
Alternatively, the terminal may display the first target content; and meanwhile, the terminal can transmit the second target content to the display equipment for display. The server feeds back different contents simultaneously according to different target objects, so that devices with different sizes can acquire the contents suitable for being displayed on the devices. It should be noted that, when the target screen-throwing mode is multi-screen display, the display mode corresponding to the terminal may be the same as the display mode corresponding to the display device, and the content request message may not include the ID of the target object, that is, the terminal only needs to receive the target content in one display mode, and display the target content on the terminal and the display device simultaneously.
For example, example 1: the corresponding display scale of the display parameters is 16:9, the screen-throwing mode is single screen display, the identification of the display mode is 01, and the ID of the target object is a projector. The target content meets the transverse screen display mode, the single screen display selected by the user is performed, and the target content is decoded and encoded after being acquired by the terminal, transmitted to the display equipment for decoding and transverse screen display.
Example 2: the display parameters are correspondingly displayed as 16:9, the screen-throwing mode is multi-screen display, the identification of the display mode is 10 and 01, and the target object ID is a projector and an STA; the STA corresponds to the first target content (vertical screen display mode), and the projector corresponds to the second target content (horizontal screen display mode). The user selects multi-screen display, the first target content is decoded by the terminal and displayed on a vertical screen of the terminal; and the second target content is decoded and encoded through the terminal, transmitted to display equipment for decoding and transverse screen display.
Optionally, when the target screen-throwing mode is single screen display or only the target content is displayed on the display device, an operation area corresponding to the target content can be displayed on the terminal at the same time when the target content is displayed on the display device, and the operation area can operate the target content on the display device; for example, if the target content is video, operations such as pause, fast forward, next set, etc. can be performed through the operation area of the terminal.
It should be noted that, if the display parameter is the screen resolution, the display ratio may be correspondingly set; if the display parameters further include refresh rate, the frame rate of the target content sent by the server should be less than or equal to the refresh rate in the display parameters, so as to support the display device.
In some embodiments, when the screen of the terminal is a folding screen, the corresponding display scale of the terminal may be changed when the screen of the terminal is unfolded or folded. Therefore, the terminal can also detect the screen state of the terminal in real time, and when detecting the screen state change, the terminal determines the current screen state and the target display proportion corresponding to the current screen state; the current screen state may include a folded state and an unfolded state, and a display ratio corresponding to the folded state may be different from a display ratio corresponding to the unfolded state. Transmitting a current content request message to a server, wherein the current content request message comprises a target display proportion; receiving a current content response message, and obtaining first target content meeting a target display proportion according to the content response message; first target content satisfying a target display scale is displayed. Therefore, based on the screen state change of the terminal, the server feeds back different target contents according to the display scale so that the change of the screen state matches with the corresponding change of the content picture.
In some embodiments, a display device receives target content and determines a display mode of the target content; when the display mode is a vertical screen display mode, the display module of the display equipment is controlled to be in a first state corresponding to the vertical screen display mode; when the display mode is a horizontal screen display mode, the display module of the display device is controlled to be in a second state corresponding to the horizontal screen display mode. For example, if the display device is a projector, the display module may be a DMD chip, an LCD, an LCOMS, etc., and the first state is as shown in fig. 1c, where 1 and 3 are focusing lens groups, so as to implement beam shaping control, and 2 is a mirror, typically an adjustable component; and 5 is a TIR prism, 6 is a DMD chip, and 7 is a lens. In the second state, the DMD chip 6 in fig. 1c is rotated by 90 degrees about the central axis, and after the state of the DMD chip is changed, other corresponding optical devices can be adjusted adaptively. When the target content is switched from the vertical screen display mode to the horizontal screen display mode, the display module can be controlled to rotate from the first state to the second state.
It should be noted that, the content request message may be directly transmitted to the display device after encoding the content currently displayed by the terminal without executing the generation of the content request message and the transmission of the content request message to the server, and the display device may determine the display mode of the content after receiving the content, and control the display module of the display device to be in a corresponding state according to the display mode. Therefore, the target content corresponding to different display modes can be not stored in the server, so that the content displayed by the display device can be matched with the display mode of the display device while the computing resources are saved.
In this embodiment, when the screen projection is triggered, a content request message may be sent to the server, requesting for target content that satisfies the display mode of the display device; the server returns a response message to the terminal, and the target content can be obtained according to the response message; then, sending target content to the display equipment, wherein the target content is adapted to the display mode of the display equipment, so that stretching or clipping of the content is not needed, a non-projection display area does not exist during display, for example, black edges do not exist in the display area of a projector; the content displayed by the display device may be adapted to be displayed on the display device. Therefore, the user experience can be improved by the scheme.
In order to better implement the above method, the present application further provides a screen projection device, which may be specifically integrated in an electronic device, for example, in this embodiment, the method of the present application will be described in detail by taking the case that the screen projection device is specifically integrated in a smart phone.
