Method, device and system for controlling screen projection

A method for controlling screen projection, comprising:

• sending, by a screen projection server, a device list of a first terminal to the first terminal, wherein the device list is generated by the screen projection server according to identification information of a second terminal, the device list includes the identification information of the second terminal, the first terminal and the second terminal are configured to accesses the screen projection server, the first terminal is a controlling end that performs screen projection control, the second terminal is a controlled end on which screen projection control is performed by the first terminal, and the second terminal and the first terminal are in the same local area network;
• receiving, by the screen projection server, a screen projection control instruction sent by the first terminal, wherein the screen projection control instruction includes the identification information of the second terminal, the screen projection control instruction is determined according to a selection instruction received by the first terminal, and the selection instruction is used to select the identification information of the second terminal from the device list;
• and
• forwarding, by the screen projection server, the screen projection control instruction to the second terminal corresponding to the identification information of the second terminal, so as to control the second terminal to project the screen to a first screen projection receiving end;
• wherein, the first terminal, the second terminal, and the first screen projection receiving end are all installed with screen projection application software, the screen projection application software installed on the first terminal and the second terminal is used to acquire display contents of the first and second terminals as screen projection data and send the screen projection data to the first screen projection receiving end, and the screen projection application software installed on the first screen projection receiving end is used to receive the screen projection data, convert the screen projection data to obtain screen projection contents, and display the screen projection contents.

A system for controlling screen projection, comprising:

• a first terminal configured to acquire a device list, receive a selection instruction, and send a screen projection control instruction to a screen projection server, wherein the device list is generated by the screen projection server according to identification information of a second terminal, the device list includes the identification information of the second terminal, the first terminal and the second terminal are configured to access the screen projection, the first terminal is a controlling end that performs screen projection control, the second terminal is a controlled end on which screen projection control is performed by the first terminal, the second terminal and the first terminal are in the same local area network, and the selection instruction is used to select the identification information of the second terminal from the device list;
• the screen projection server, wherein the screen projection server is configured to communicate with the first terminal and forward the screen projection control instruction to the second terminal corresponding to the identification information of the second terminal, and wherein the screen projection control instruction includes the identification information of the second terminal;
• and
• the second terminal, wherein the second terminal is configured to communicate with the screen projection server and a first screen projection receiving end and project the screen to the first screen projection receiving end according to the screen projection control instruction;
• and
• the first screen projection receiving end, wherein the first screen projection receiving end is configured to communicate with the second terminal and display screen projection contents of the second terminal;
• wherein, the first terminal, the second terminal, and the first screen projection receiving end are all installed with screen projection application software, the screen projection application software installed on the first terminal and the second terminal is used to acquire display contents of the terminals as screen projection data and send the screen projection data to the first screen projection receiving end, and the screen projection application software installed on the first screen projection receiving end is used to receive the screen projection data, convert the screen projection data to obtain the screen projection contents, and display the screen projection contents.
