Video conference system

1 . A video conference system, comprising:

at least one transmitter device, connected to at least one information processing device; and

a receiver device, wirelessly connected to the transmitter device, the receiver device wirelessly receiving a video and audio data related to the information processing device transmitted by the transmitter device, when the transmitter device is triggered to stop screen sharing, the receiver device generating a standby screen and when the receiver device is connected to a video conference screen management device, the receiver device does not output the standby screen to the video conference screen management device;

wherein a physical button is disposed on the transmitter device, the physical button is triggered to wirelessly transmit a real-time screen of the information processing device to the receiver device, and then the receiver device transmits the real-time screen to the video conference screen management device; when the physical button is triggered to stop screen sharing of the transmitter device, the receiver device generates the standby screen; when the video conference screen management device receives a plurality of video conference screens from other devices, the video conference screen management device manages the plurality of video conference screens to distribute the plurality of video conference screens to be displayed on different display areas of a display connected to the video conference screen management device respectively.

2 . The video conference system of claim 1 , wherein when the transmitter device is not connected to the receiver device, the receiver device outputs the standby screen as a connection operation scenario; if the receiver device is connected to the video conference screen management device, the receiver device does not output the standby screen to the video conference screen management device.

3 . The video conference system of claim 1 , wherein the receiver device comprises a first port, and the first port is connected to the video conference screen management device through a first channel; the receiver device does not output the standby screen to the video conference screen management device by setting the first port, so that the first channel does not output or close.

4 . The video conference system of claim 3 , wherein the receiver device comprises an image processing unit coupled to the first port; the image processing unit does not output the standby screen to the first port.

5 . The video conference system of claim 1 , wherein whether the receiver device is connected to the video conference screen management device is determined through an exchange of extended display identification data (EDID) between the receiver device and the video conference screen management device.

6 . The video conference system of claim 1 , wherein whether the receiver device is connected to the video conference screen management device is determined through a loopback of universal serial bus (USB) control signal or high-definition multimedia interface (HDMI) consumer electronics control (CEC) signal.

7 . The video conference system of claim 1 , wherein when the transmitter device does not trigger the screen sharing function or interrupts the connection between the transmitter device and the receiver device and does not wirelessly transmit the screen of the connected information processing device to the receiver device, the receiver device triggers the standby screen.

8 . The video conference system of claim 1 , wherein when the receiver device triggers the standby screen and the receiver device is connected to a first display, the receiver device outputs the standby screen to the first display.

9 . The video conference system of claim 1 , wherein the receiver device has a second port, the second port is connected to the first display through a second channel, the first display receives the standby screen, but the video conference screen management device does not receive the standby screen.

10 . The video conference system of claim 1 , wherein the plurality of video conference screens does not include the standby screen transmitted from the receiver device.

11 . The video conference system of claim 1 , wherein the video conference screen management device is connected to the display through a HDMI channel.

12 . The video conference system of claim 1 , wherein the video conference screen management device is also connected to a camera, and the camera obtains a video conference screen and provides the video conference screen to the video conference screen management device.

13 . A video conference system, comprising:

at least one transmitter device, connected to at least one information processing device; and

a receiver device, wirelessly connected to the transmitter device, the receiver device wirelessly receiving a video and audio data related to the information processing device transmitted by the transmitter device, when the receiver device triggers a standby screen and the receiver device is connected to a video conference screen management device, the receiver device does not output the standby screen to the video conference screen management device;

wherein a physical button is disposed on the transmitter device, the physical button is triggered to wirelessly transmit a real-time screen of the information processing device to the receiver device, and then the receiver device transmits the real-time screen to the video conference screen management device; when the physical button is triggered to stop screen sharing of the transmitter device, the receiver device generates the standby screen; when the video conference screen management device receives a plurality of video conference screens from other devices, the video conference screen management device manages the plurality of video conference screens to distribute the plurality of video conference screens to be displayed on different display areas of a display connected to the video conference screen management device respectively.
