Abstract: A video conferencing system is provided. The video conferencing system includes a first video conferencing apparatus and a second video conferencing apparatus. A video/audio connection of a video conference between the first and second video conferencing apparatuses is established via an SIP channel. When the video/audio connection of the video conference has been established, a transparent layer is activated on the first and second conferencing apparatuses. When the first and second video conferencing apparatuses are switched to an external output projection mode, first and second touch events are input on the first and second video conferencing apparatus, and the first and second touch events are respectively transmitted to the second and first video conferencing apparatuses via the SIP channel. The first and second video conferencing apparatuses draw the second and first touch events on a first user interface and a second user interface.

Abstract: A video conferencing system is provided. The video conferencing system includes: a first communication device, configured to receive a video signal from a host, and convert the video signal into a first video stream; and a second communication device, configured to receive a second video stream of a scene captured by an image capturing unit, and receive the first video stream from the first communication device by using a wireless communication protocol, wherein the second communication device selects one of the first video stream and the second video stream according to a switching signal, and transmits the selected video stream to an electronic system, wherein when receiving the switching signal, the second communication device stops transmitting the selected video stream to the electronic system for a predetermined time period, and transmits header information of another video stream to the electronic system, thereby resetting decoding settings of the system.
