The other mobile devices directly feed back through the central control server, and the large-screen device feeds back the feedback information through the private network server.
And S33, acquiring and playing the screen data of the large screen according to the screen return request of the user.
Specifically, when a user sends a screen return request through the mobile device, the screen return request is forwarded to the private network server, the private network server sends a corresponding instruction to the large-screen device connected with the private network server, the large-screen device sends screen data displayed by the large-screen device to the private network server under the control of the corresponding instruction, the private network server sends the screen data to the mobile device, and the mobile device displays the screen data through a display interface of the mobile device.
In addition, because the screen of the mobile device is generally smaller and does not need larger screen data, in order to save traffic or reduce the burden of the corresponding server, the large-screen device can be controlled to compress the screen data and then transmit the compressed screen data to the central control server through the private network server, and the central control server sends the compressed screen data to the mobile device, so that the forwarding task amount of the central control server and the private network server can be reduced.
The compression ratio of the compression processing of the screen data here is related to the screen data of the mobile device, such as the screen size and the resolution of the screen.
Through the operation, the large-screen equipment can be directly or indirectly operated based on the mobile equipment, corresponding feedback information is obtained, and interaction between the mobile equipment and the large-screen equipment is facilitated.
In addition, in another embodiment of the present application, the following steps are further included, as shown in fig. 4.
And S4, controlling the mobile device or the large-screen device to leave the room according to the room leaving request of the user.
That is, when the user sends the room leaving request through the mobile device, the central control server moves other mobile devices, the large-screen device, and even the mobile device out of the corresponding room according to the specific parameters of the request, so as to further disconnect or incorporate other mobile devices or the large-screen device into the room.
And S5, controlling the mobile equipment to disconnect according to the disconnection request.
That is, when the user sends the disconnection request through the mobile device, the central control server disconnects the mobile device sending the request from itself according to the request, so as to subsequently receive the connection request of other mobile devices or the mobile device and realize the connection again.
