Document Type and Number:
WIPO Patent Application WO/2020/042321
Kind Code:
A1
Abstract:
Disclosed in the present application are a method, apparatus and system for controlling a projection screen. The method comprises: a first terminal acquiring a device list, wherein the device list comprises identification information of a second terminal, and the second terminal is a terminal that accesses the same server as the first terminal; the first terminal receiving a selection instruction, wherein the selection instruction is used to select target identification information from the device list; and the first terminal sending a projection screen control instruction to the server, wherein the projection screen control instruction comprises target identification information, and the projection screen control instruction is forwarded to a target second terminal corresponding to the target identification information by means of the server so as to control the target second terminal to project a screen to a first projection screen receiving end. The present application solves the problem in existing projection screen technology in which a projection screen sending end may only perform projection screen control on content thereof, leading to the need to separately control different projection screen sending ends when there are a plurality of projection screen sending ends, and the operations are thus cumbersome and complicated.
