The screen projection control method comprises the steps that when a first screen projector is used for screen projection, acquiring a first identifier of the used screen projector and determining that the first screen projector is a main screen projector or an auxiliary screen projector; receiving a screen projection request sent by a second screen projector, obtaining a second identifier of thescreen projector sending the screen projection request, and determining that the second screen projector is a main screen projector or an auxiliary screen projector; if the first screen projector is an auxiliary screen projector and the second screen projector is a main screen projector, responding to the screen projection request and switching to display screen projection content sent by the second screen projector; and if the first screen projector is the main screen projector, refusing to display the screen projection content sent by the second screen projector. When the screen projector isset as the main screen projector for screen projection, interference of other screen projectors is avoided, screen projection can be used stably and reliably, conference efficiency can be improved, when the auxiliary screen projector is used, the main screen projector can be switched to conveniently, use is convenient, and user experience can be improved.
Description
technical field [0001] The present application belongs to the field of screen projection, and in particular relates to a screen projection control method, device and system. Background technique [0002] With the development of wireless communication technology, more and more devices adopt wireless communication, which can not only save the wiring cost of equipment, but also improve the convenience of equipment layout, making the equipment layout more beautiful and efficient. For example, after a wireless screen projector is installed on a display device such as a TV, a notebook, etc., the screen of a smart phone or other device can be projected to the display device, which is convenient for users to watch. [0003] The current wireless screen projectors can usually project the screen content of multiple control terminals to the large screen. During the meeting, they often encounter the phenomenon of preemptive projection, which makes the stability of the projection poor and...
