[0046] In one embodiment, after the device establishes a connection relationship with the conference large screen, the device can provide a screen sharing data stream to the conference large screen through the connection relationship, wherein the screen sharing data stream comprises a screen sharing video data stream and a screen sharing audio data stream.

[0047] In one embodiment, after the device establishes a connection relationship with the conference large screen, the conference large screen further acquires the connection time of each connected device, sorts the connected devices according to the connection time, generates a connected device list, and displays the connected device list on the screen, wherein the connected device list is displayed on the side of the conference large screen, and the connected device list does not occupy the device screen content display space.

[0048] In one embodiment, the conference large screen can set a maximum number of connected devices; preferably, in this embodiment, the maximum number of connected devices of the conference large screen is set to 9, that is, the conference large screen can display screen content of 9 connected devices at a time.

[0049] In an embodiment, based on the maximum number of connected devices set by the conference large screen, the screen sharing mode selection mechanism is set to a first screen sharing mode, a second screen sharing mode, a third screen sharing mode, a fourth screen sharing mode, a fifth screen sharing mode, a sixth screen sharing mode, a seventh screen sharing mode, an eighth screen sharing mode, and a ninth screen sharing mode.

The ninth screen sharing mode is an upper three-middle three-lower three display mode, as shown in Figure 11 Figure 11 is a schematic diagram of the ninth screen sharing mode.

[0051] Preferably, each screen content display interface is set to maintain a 16:9 aspect ratio mode to provide users with a better viewing experience. ​​​​​​​​​

[0052] In an embodiment, when the number of currently connected devices is 1, 1 is input into the screen sharing mode selection mechanism, which automatically selects the first screen sharing mode according to the number of currently connected devices, and after the number of currently connected devices is updated, the screen sharing selection mode is automatically updated according to the number of currently connected devices, that is, the screen sharing mode is automatically assigned according to the number of screen sharing, and the screen content is displayed.

[0053] Step 102: Real-time detection of the voice input state of each currently connected device, when the voice input of the first connected device is detected, it is judged whether the voice input time of the first connected device is greater than a preset time threshold, if yes, the first screen content of the first connected device is automatically set to full screen display mode, and when the voice input of the first connected device is detected, the full screen display state is exited.

[0054] In an embodiment, when the device is connected to the conference large screen, the conference large screen system also detects the microphone access state of the currently connected device, and when the microphone access state of the currently connected device is detected to be on, the voice input state of each currently connected device is detected in real time.

[0055] In an embodiment, it is judged whether the voice input time of the first connected device is greater than a preset time threshold, wherein the preset time threshold is a time threshold automatically defined by the user; preferably, the preset time threshold is set to 3s; which can avoid false detection of voice input, improve the fault tolerance of voice detection, and avoid false occupation of full screen display state.

[0056] In an embodiment, when it is detected that the voice input time of the first connected device is greater than the preset time threshold, the first screen content of the first connected device is obtained, and the first screen content is set at the top of the display screen of the conference large screen; at the same time, the screen content corresponding to other connected devices except the first connected device in the currently connected devices is set to an invisible state.

[0057] In an embodiment, when the first screen content of the first connected device is set at the top of the display screen of the conference large screen, the conference large screen system also sends a device preemption full screen prompt to other connected devices.

[0058] In an embodiment, each connected device is also provided with a full screen function identifier, when other connected devices need to preempt the full screen state, the full screen function identifier is clicked to make the full screen function identifier issue a full screen display device switching instruction.

[0059] In an embodiment, the full-screen display device switching instruction issued by the current connection device is detected in real time, and when the full-screen display device switching instruction is detected to be issued by the second connection device, the second screen content corresponding to the second connection device is acquired in real time, and the second screen content is set to the full-screen display mode, wherein the second connection device is the connection device that issues the full-screen display device switching instruction.

[0060] In an embodiment, the full-screen display device switching instruction contains a unique identifier corresponding to the connection device that issues the instruction, and when the conference large-screen system detects the full-screen display device switching instruction in real time, the screen content of the connection device is acquired by acquiring the unique identifier corresponding to the connection device carried in the full-screen display device switching instruction.

[0061] In an embodiment, when the first screen content of the first connection device is in the full-screen display mode, and no full-screen display device switching instruction is received from other connection devices during the process, the voice input condition of the first connection device is detected in real time, and when it is detected that there is no voice input of the first connection device within a preset time, it is considered that there is no voice input of the first connection device. At this time, the conference large-screen system controls the first screen content of the first connection device to exit the full-screen display state, and the number of current connection devices is acquired again, and the number of connection devices is input into the screen sharing mode selection mechanism, so that the screen sharing mode selection mechanism selects the screen sharing mode, and displays the screen content corresponding to the current each connection device according to the screen sharing mode.

[0062] Preferably, when the first screen content of the first connection device is in the full-screen display mode, the microphone access state of the first connection device can also be acquired in real time, and when the microphone access state of the first connection device is off, it is also considered that there is no voice input of the first connection device. At this time, the conference large-screen system controls the first screen content of the first connection device to exit the full-screen display state.

[0063] Preferably, when the first screen content of the first connection device is in the full-screen display mode, the first connection device can also be detected to issue a full-screen state exit instruction, and if yes, the conference large-screen system controls the first screen content of the first connection device to exit the full-screen display state.

[0064] In an embodiment, when the connection device is in the full-screen state, the full-screen function identifier can be clicked to make the full-screen function identifier issue a full-screen state exit instruction; and when the connection device is in the non-full-screen state, the full-screen function identifier can be clicked to make the full-screen function identifier issue a full-screen display device switching instruction.

[0065] In an embodiment, the conference large screen can control multiple connection devices, and a single connection device can only control the screen content shared by itself, so as to achieve a screen sharing mechanism for collaborative work.
