Video conferencing system and associated interaction display method
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.
1. A video conferencing system, comprising:
a first video conferencing apparatus, comprising a first touch panel; and
a second video conferencing apparatus, comprising a second touch panel,
wherein a video/audio connection of a video conference between the first video conferencing apparatus and the second video conferencing apparatus is established via a session initialization protocol (SIP) channel,
wherein when the video/audio connection of the video conference has been established, a transparent layer is activated on the first video conferencing apparatus and the second conferencing apparatus,
wherein when the first video conferencing apparatus and the second video conferencing apparatus are switched to an external output projection mode, a first touch event and a second touch event are input on the first touch panel and the second touch panel, and the first touch event and the second touch event are respectively transmitted to the second video conferencing apparatus and the first video conferencing apparatus via the SIP channel,
wherein the first video conferencing apparatus and the second video conferencing apparatus draw the second touch event and the first touch event on a first user interface and a second user interface, wherein the first user interface is identical to the second user interface.
2. The video conferencing system as claimed in claim 1 , wherein the first touch panel and the second touch panel are optical touch panels.
3. The video conferencing system as claimed in claim 1 , wherein the first touch panel and the second touch panel are capacitive touch panels.
4. The video conferencing system as claimed in claim 1 , wherein the external output projection mode indicates that a video output device outputs a screen to the first video conferencing apparatus and the second video conferencing apparatus, and the screens are simultaneously displayed on the first video conferencing apparatus and the second video conferencing apparatus.
5. The video conferencing system as claimed in claim 1 , wherein the first video conferencing apparatus and the second video conferencing apparatus transmit the first touch event and the second touch event to the second video conferencing apparatus and the second video apparatus via an operating framework layer, respectively.
6. A video conference interaction display method, for use in a video conferencing system, wherein the video conferencing system comprises a first video conferencing apparatus and a second video conferencing apparatus, the method comprising:
establishing a video/audio connection of a video conference between the first video conferencing apparatus and the second video conferencing apparatus via a session initialization protocol (SIP) channel;
activating a transparent layer on the first video conferencing apparatus and the second conferencing apparatus when the video/audio connection of the video conference has been established;
when the first video conferencing apparatus and the second video conferencing apparatus are switched to an external output projection mode, utilizing the first video conferencing apparatus and the second conferencing apparatus to input a first touch event and a second touch event, and respectively transmitting the first touch event and the second touch event to the second video conferencing apparatus and the first video conferencing apparatus via the SIP channel; and
utilizing the first video conferencing apparatus and the second video conferencing apparatus to draw the second touch event and the first touch event on a first user interface and a second user interface, wherein the first user interface is identical to the second user interface.
7. The video conference interaction display method as claimed in claim 6 , wherein the first video conferencing apparatus comprises a first touch panel, and the second video conferencing apparatus comprises a second touch panel, and the first touch panel and the second touch panel are optical touch panels.
8. The video conference interaction display method as claimed in claim 6 , wherein the first video conferencing apparatus comprises a first touch panel, and the second video conferencing apparatus comprises a second touch panel, and the first touch panel and the second touch panel are capacitive touch panels.
9. The video conference interaction display method as claimed in claim 6 , wherein the external output projection mode indicates that a video output device outputs images on a screen to the first video conferencing apparatus and the second video conferencing apparatus, and the screen is simultaneously displayed on the first video conferencing apparatus and the second video conferencing apparatus.
10. The video conference interaction display method as claimed in claim 6 , further comprising:
utilizing the first video conferencing apparatus and the second video conferencing apparatus to transmit the first touch event and the second touch event to the second video conferencing apparatus and the second video apparatus via an operating framework layer, respectively.
