As shown in fig. 5, the terminal a, the terminal B, the terminal C, and the terminal F may access the wireless module through Wi-Fi, and may set to project the screen data of the terminal a, the terminal B, and the terminal C to the terminal F through wireless transmission, and the terminal F may display the screen data of the terminal a, the terminal B, and the terminal C in different areas. Meanwhile, the terminal F can select one of the terminal A, the terminal B and the terminal C at any time to control the screen of the terminal F, the control operation principle is that the operation coordinate or the click event of the terminal F is converted and transmitted to a specific screen projection sending terminal in the terminal A, the terminal B and the terminal C, and the screen of the screen projection sending terminal is controlled, so that the reverse control effect is achieved.

If the user operates the screen projection application of the screen projection receiving terminal to stop displaying the screen data, the user can be controlled to stop receiving the screen data.

In the screen projection process of the embodiment, if other new terminals are connected and wirelessly join the current screen projection scene, the screen information (including the size and the resolution) of the terminals needs to be synchronized to the terminal with the largest screen size, meanwhile, the terminal with the largest screen size needs to synchronize the screen information of the terminal to the newly joined terminal, and the terminal with the largest screen size can be reselected from the current multiple terminals (including the newly joined terminal), and is defaulted as a screen projection receiving terminal, or is selected as a screen projection sending terminal; optionally, if the terminal with the largest screen size is a screen-casting receiving terminal at the beginning, if other new terminals are connected to wirelessly join the current screen-casting scene in the screen-casting process, the newly-joined terminal can be directly used as a screen-casting sending terminal, screen information of the newly-joined terminal is synchronized to the terminal with the largest screen size, and the terminal with the largest screen size divides a screen area again according to the number of the current screen-casting sending terminals and the screen information of each terminal so as to display screen data sent by each screen-casting sending terminal; optionally, if the terminal with the largest screen size is the screen-projecting sending terminal at the beginning, if other new terminals are connected to wirelessly join the current screen-projecting scene in the screen-projecting process, the newly-joined terminal can be directly used as the screen-projecting receiving terminal, screen information of the newly-joined terminal is synchronized to the terminal with the largest screen size, and the terminal with the largest screen size projects screen data of the terminal to the newly-joined terminal.

In the reverse control of the embodiment, the screen projection receiving terminal converts the operation coordinates or events thereof according to the size of the screen projection sending terminal, the screen resolution and the like, transmits the converted operation coordinates or events to the screen projection sending terminal through the RTSP protocol, and performs the reverse control on the screen projection sending terminal.

Meanwhile, F can select one of the areas to click and magnify to the whole screen, and carries out reverse control operation on the terminal corresponding to the area.

Step S608, when another new terminal is connected to the wireless module W and joins the current screen projection scene, screen information of the new terminal needs to be synchronized to the large-screen terminal F, and the newly joined terminal starts the installed screen projection application as a screen projection sending terminal to start screen projection to the large-screen terminal F.

In this embodiment, the terminal F may divide its screen area again according to the number of the current screen projection sending terminals, so as to display the screen data of each screen projection sending terminal.

And step S609, the screen data of the large-screen terminal F is projected to the terminal A and the terminal B.
