Fig. 1 is a schematic view of an application scenario to which a wireless screen projection method provided in an embodiment of the present invention is applied, and as shown in fig. 1, a wireless screen projection system illustrated in the schematic view includes a screen projector, a data source device, and a display device; the screen projector is provided with a screen projecting key which is an entity key. The screen projector is provided with a wired communication interface and a wireless communication interface, and the wired communication interface is, for example, a Universal Serial Bus (USB) interface illustrated in the figure, but is not limited thereto. The screen projector is connected with the data source equipment through the wired communication interface and is wirelessly connected with the display equipment through the wireless communication interface, so that a wireless environment for wireless screen projection is provided. It will be appreciated that a corresponding wireless communication interface is provided in the display device to enable wireless communication with the screen projector.
The data source device is, for example, a PC, a notebook computer, or the like; the display device may be a display screen, a television set, or the like.
In practical application, the wireless communication connection between the screen projector and the display device needs to be established first, so as to facilitate subsequent wireless screen projection processing. In an alternative embodiment, the display device may be understood as a Wireless compatibility authentication (Wi-Fi) router, and after the screen projector is connected with the data source device, the corresponding Wi-Fi signal may be searched for matching connection therewith.
Before specifically describing the wireless screen projection method provided by the embodiment of the present invention, for convenience of subsequent understanding, first, referring to fig. 2a to 2e, a change of a screen display effect of a display device with each pressing operation of a screen projection key of a screen projector by a user is described.
Assuming that the screen projector has been connected to the data source device, the current display device is powered on, but the screen, i.e. the display screen, is in the screen-off state shown in fig. 2 a. When a user presses a screen projection key of the screen projection device once, the screen projection device controls the screen display effect of the display device as shown in fig. 2b, an initial navigation interface is displayed in the screen, that is, the initial navigation interface is in an initial navigation interface display state, and the initial navigation interface may include one or more navigation icons, such as a whiteboard, a manuscript presentation, and other icons illustrated in the figure, wherein when any icon is clicked, a corresponding function may be directly triggered, and a related secondary menu may also be displayed. For example: after the whiteboard icon is clicked, calling of a whiteboard function is triggered, a whiteboard function interface is displayed on a screen, and a user can perform operations such as drawing, character input and the like in the interface; after the manuscript presentation icon is clicked, a secondary menu as shown in fig. 2b may pop up, where the secondary menu includes, for example, menu items such as a wireless screen, a local file, and a usb disk, where each menu item may correspond to an acquisition channel of data to be screened. The initial navigation interface can be used for corresponding control operation when the user is positioned at the display equipment side.
When the initial navigation interface is displayed in the display device, if the user presses the screen projecting key of the screen projecting device again at this time, the screen projecting device controls the screen display effect of the display device to be as shown in fig. 2c, at this time, the display device switches the screen display state to the wireless screen projecting display state, which is the state of synchronous display of the data source device and the display device, that is, the screen data to be projected displayed in the data source device is transmitted to the display device for synchronous display, as in fig. 2c, if the screen data to be projected is the 2017-year traffic statistical table indicated in the figure, the 2017-year traffic statistical table is displayed in the screen of the display device in the wireless screen projecting display state.
When the display device is in the wireless screen projection display state, if the user presses the screen projection key of the screen projection device again at the moment, the screen projection device controls the screen display effect of the display device to be as shown in fig. 2d, and the display device switches the screen display state to the initial navigation interface display state again at the moment.
When the display device is in the initial navigation interface display state shown in fig. 2d, if the user presses the screen projection key of the screen projector again at this time, the screen projector controls the screen display effect of the display device to be as shown in fig. 2e, and the display device switches the screen display state to the screen off state at this time.
Fig. 2a to 2e illustrate the screen display effect variation of the display device during the wireless screen projection operation, which can be considered as follows: the process from fig. 2a to fig. 2c is a process of entering wireless screen projection, and the process from fig. 2d to fig. 2e is a process of exiting wireless screen projection.
The following description will be made of a control principle of realizing the screen display effect of the display device by standing at the angle of the screen projector and combining the following embodiments.
Fig. 3 is a schematic flow chart of a first embodiment of a wireless screen projection method according to an embodiment of the present invention, as shown in fig. 3, the method includes the following steps:
301. and responding to the pressing operation of a screen projection key of the screen projector, and at least acquiring the current screen display state of the display equipment.
302. And controlling the display equipment to be switched to a screen display state of entering or exiting the wireless screen projection according to the acquired screen display state.
In terms of the screen projector, the screen projector controls the screen display state of the display device based on the fact that the screen projector presses the screen button of the screen projector currently, and the screen display state of the display device is the latest screen display state of the display device.
The reason why it is at least necessary to obtain the screen display state that the display device is in before the pressing operation is that, in combination with the screen display effect change situations of fig. 2a to 2e, the situation that the same interface is displayed at different stages may occur, and at this time, it may be necessary to obtain the previous screen display state, that is, to obtain two screen display states that the display device is in before the pressing operation.
In practice, in response to a pressing operation of the screen projecting key by the user, the screen projecting device may send an acquisition request to the display device to acquire a current screen display state of the display device, so that the display device feeds back the current screen display state to the screen projecting device.
Optionally, a state identifier corresponding to each screen display effect may be preconfigured on the display device side, for example, the screen closed state identifier is 00, the display state identifier of the initial navigation interface is 01, and the display state identifier of the wireless screen projection is 02. Therefore, the display device can feed back the state identifier representing the screen display state to the screen projector to inform the screen projector of the current screen display state of the display device.
Optionally, the display device may also send the intercepted screen image to the screen projector through operation of intercepting the screen, so that the screen projector determines the current screen display state of the display device by recognizing features of the screen image. For example, if the screen image is identified as a black screen, the screen image is considered to be in a screen display state with the screen closed; if the screen image is identified to have the preset navigation icon, the screen image is considered to be in the display state of the initial navigation interface; and if other data contents are identified in the screen image, the screen image is considered to be in a wireless screen projection display state.
After the screen projector obtains one or two screen display states, the screen display state obtained may be combined to control the display device to switch to the screen display state entering or exiting the wireless screen projector, and specifically, the screen display state obtained and the change sequence of the screen display states shown in fig. 2a to fig. 2e may be combined to determine what screen display state the display device should enter next.
Such as: based on the foregoing examples of status flags of various screen display statuses, the sequence of changes of the screen display statuses shown in fig. 2a to 2e is as follows: 00,01,02,01,00, thereby, according to the state identifier of the currently obtained screen display state, determining which sequence position the screen display state of the display device is currently in, and then controlling the display device to enter the next screen display state to conveniently realize the control of the display device.
How the screen projector controls the screen display state of the display device is described below with reference to fig. 4 and 5.
Fig. 4 is a schematic flow chart of a second embodiment of a wireless screen projection method according to an embodiment of the present invention, and as shown in fig. 4, the method includes the following steps:
401. and responding to the pressing operation of a screen projection key of the screen projector, and acquiring the current first screen display state of the display equipment.
402. And if the first screen display state is the initial navigation interface display state, acquiring a second screen display state before the first screen display state.
The sequence of changes in screen display state as exemplified in the foregoing embodiment: 00,01,02,01,00, if the user presses the screen-projection key and the display device is in the initial navigation interface display state 01, since two sequence positions are 01 in the change sequence, it cannot be determined which screen display state the display device should be controlled to enter next based on the initial navigation interface display state only. Therefore, at this time, it is also necessary to obtain the previous second screen display state, so as to control the display device to switch the screen display state in combination with the first screen display state box and the second screen display state.
403. And if the second screen display state is a screen closing state, controlling the display equipment to be switched to a wireless screen projection display state, and controlling the data source equipment to acquire the data to be projected and transmit the data to be projected received from the data source equipment to the display equipment for display.
404. And if the second screen display state is the wireless screen projection display state, controlling the display equipment to be switched to a screen closing state.
As can be seen from the above change sequence, the second screen display state before the initial navigation interface display state 01 may be the screen off state 00, or may be the wireless screen projection display state 02.
When the second screen display state is the screen closing state 00, it is indicated that the user needs to enter the wireless screen projection display state when pressing the screen projection key at this time, so as to perform wireless screen projection from the data source device to the display device, at this time, the screen projector can send a switching control command to the display device to control the display device to switch to the wireless screen projection display state, and at this time, the screen projector also needs to send an indication signal to the data source device to control the data source device to collect the screen data to be projected, the data source device sends the collected screen data to be projected to the screen projector, and the screen projector transmits the screen data to be projected received from the data source device to the display device for display, namely, the screen data is displayed in the screen interface of the current display device.
It should be noted that the process of acquiring the data to be projected by the data source device, and the processes of compressing and encoding the data to be projected, which may be performed by the data source device, may be implemented by using the prior art, and the embodiment of the present invention is not described in detail.
When the second screen display state is the wireless screen projection display state 02, it indicates that the user presses the screen projection key at this time to want to close the screen of the display device, that is, finally quit the wireless screen projection function, and at this time, the screen projection device sends a switching control command to the display device to control the display device to switch to the screen closing state.
Fig. 5 is a schematic flow chart of a third embodiment of a wireless screen projection method provided in an embodiment of the present invention, and as shown in fig. 5, the method includes the following steps:
501. and responding to the pressing operation of a screen projection key of the screen projector, and acquiring the current first screen display state of the display equipment.
502. And if the first screen display state is the wireless screen projection display state, controlling the display equipment to switch to the initial navigation interface display state, and controlling the data source equipment to stop collecting the screen data to be projected.
If the screen-projecting key is pressed, the display device is in the wireless screen-projecting display state 02, which indicates that the user is ready to quit the wireless screen-projecting function, but at this time, the user may need to perform other operations, such as invoking a whiteboard function, etc., and therefore, as described in the foregoing change sequence, the display device should be controlled to switch to the initial navigation interface display state 01, so that the initial navigation interface is displayed in the screen of the display device. In addition, the wireless screen projection function is quitted, and the data source equipment does not need to acquire the data to be projected, so that the screen projector needs to send an indication signal to the data source equipment at the moment so as to control the data source equipment to stop acquiring the data to be projected.
503. And if the first screen display state is the screen closing state, controlling the display equipment to be switched to the initial navigation interface display state.
If the screen projection key is pressed, the display device is in the screen off state 00, which indicates that the user needs to open the screen at this time to perform the subsequent triggering of the wireless screen projection function or the triggering of other functions, and therefore, as in the above change sequence, the display device should be controlled to switch to the initial navigation interface display state 01, so that the initial navigation interface is displayed in the screen of the display device.
It should be noted that, in an optional embodiment, as shown in fig. 2b, the initial navigation interface may include a button for triggering the wireless screen projecting function, and when the user is located on the display device side, the user may also click the button in the initial navigation interface to trigger the wireless screen projecting function, at this time, when the display device detects that the user performs a click operation on the button, the display device may send a wireless screen projecting start notification to the screen projecting device, and the screen projecting device controls the data source device to collect the data to be projected and transmits the data to be projected, which is received from the data source device, to the display device for displaying, so as to implement the wireless screen projecting display of the data to be projected on the display device.
In summary, the embodiment of the present invention provides a scheme that a user can control a wireless screen projection process only by operating a screen projection key of a screen projector. Specifically, when a user triggers a pressing operation on a screen projecting key of the screen projecting device, the screen projecting device can know what stage of the whole wireless screen projecting process is currently in by at least acquiring the current screen display state of the display device, so that the display device is controlled to be switched to the screen display state corresponding to the next stage based on the acquired screen display state, namely, the screen display state of the wireless screen projecting is entered or exited, and the wireless screen projecting control on the display device side can be conveniently realized only by operating the screen projecting key of the screen projecting device.
