Firmware Version 1.0.1.65
Control video and audio for conference members. It includes the
following options for each party:
- The selected party will not be heard by other parties.
- The selected party will not hear other parties.
- The video call with the selected party will turn into audio call.
If the user clicks on this icon again, a video invitation will be
sent to this party. The party has to accept the video request
in order to see the video again.
- Suspend video from the video party. Click on it again to
resume video.
Adjust the layout for the video display for video call.
The layout options might vary depending on how many video
participants are in the call, how many HDMI outputs are connected
and whether presentation is turned on or not.
For example, in a two-way video call on GVC3200 which has one
HDMI output connected, after pressing "Layout" icon, users will see
options "Average", "Remote (Local)", "Local (Remote)", "Remote"
and "Local".
Pause/resume conference. Once the conference is paused, the
device will stop sending local video/audio to the remote parties.
Turn on/off presentation.
HDMI IN or VGA IN must be plugged in first. When HDMI IN or
VGA IN is plugged in to GVC3200/GVC3202, after the user selects
"Presentation", the user can select mode "Auto" or "PC" to display
presentation.

presentation stream and the participant can show presentation.

Presentation Mode: PC
The GVC3200/GVC3202 that shares presentation will only
