And starting to judge whether the external equipment is in a standby state or a power-off state, and switching the second picture of the target screen projector to the first picture if the external equipment is in the standby state or the power-off state. The user can directly control the standby state or the shutdown state of the external equipment to realize the switching of the second picture of the target screen projector to the first picture without the operation of pulling out the data line, thereby greatly improving the user experience.
Further, when a plurality of external devices are accessed, if one accessed external device is in a standby state or a power-off state, the external device is considered to be disconnected, and a second picture is displayed according to the display proportion set by the number of the currently accessed external devices.
In an alternative embodiment, after step S220, that is, after there is an external device accessing the target screen projector, the following steps may be further performed:
and S251, judging whether other external equipment is connected to the target screen projector.
And S252, if other external equipment is connected to the target screen projector, switching the second picture of the target screen projector to a third picture of the other external equipment.
If the user needs to access a plurality of external devices for display, after one external device is accessed and the first picture of the target screen projecting device is switched to the second picture of the external device, the user can also directly access other external devices, and at the moment, the second picture of the target screen projecting device can be automatically switched to the third pictures of other external devices. Therefore, after the user accesses the external equipment, the user does not need to disconnect the external equipment and directly accesses other external equipment, and the target screen projector can display the third pictures of other external equipment, so that the method is very convenient.
Further, if the user disconnects other external devices, the third picture of the target screen projector is correspondingly switched to the second picture of the external device.
In an alternative embodiment, after step S220, that is, after there is an external device accessing the target screen projector, the following steps may be further performed:
and S261, receiving a screen projection request based on the mobile equipment and sent by the user.
And S262, acquiring the screen projection communication protocol of the mobile equipment according to the screen projection request.
And S263, judging whether the target screen projector supports the screen projecting communication protocol.
And S264, if the screen projection communication protocol is supported, switching the second picture of the target screen projector to a fourth picture of the mobile equipment.
The user can also send a screen projection request based on the mobile device, the mobile device can be an intelligent mobile terminal, such as a mobile phone, a tablet computer and the like, after receiving the screen projection request based on the mobile device sent by the user, the screen projection communication protocol of the mobile device is obtained according to the screen projection request, and whether a target screen projector supports the screen projection communication protocol is judged, wherein the supported screen projection communication protocol comprises Miracast, Dlna and Airplay. And finally, if the screen projection communication protocol is supported, the mobile equipment sends video picture data of the mobile equipment to the target screen projector through the screen projection communication protocol, so that the second picture of the target screen projector can be switched to the fourth picture of the mobile equipment.
It should be noted that, when the target screen projector is the mobile device initially connected, the fourth screen of the mobile device is the first screen of the target screen projector, and after the user accesses the external device or connects with another mobile device, the user may display the target screen projector back to the original first screen through the screen projecting request sent based on the mobile device, or may send the screen projecting request based on another mobile device to switch the target screen projector to the fourth screen of the another mobile device.
