Video Preview
Video Preview is applicable for AVC endpoints only.
Collaboration Server users can preview the video sent from the participant to the conference (MCU) and the
video sent from the conference to the participant. It enables the Collaboration Server users to monitor the
quality of the video sent and received by the participant and identify possible quality degradation.
The video preview is displayed in a separate window independent to the Collaboration Server Web Client.
All Web Client functionality is enabled and conference and participant monitoring as well as all other user
actions can be performed while the video preview window is open and active. Live video is shown in the
preview window as long as the window is open. The preview window closes automatically when the
conference ends or when participant disconnects from the conference. It can also be closed manually by
the Collaboration Server user.
