Video Preview Guidelines
2-46
RMX 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 RMX 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
RMX 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 RMX user.
• Video preview is available in Continuous Presence and Video Switching
conferences.
• Video preview window size and resolution are adjusted to the
resolution of the PC that displays the preview.
• Video Preview of the video sent from the conference to the
participant is shown according to the line rate and video parameters
of the level threshold to which the participant is connected.
• Only users with Administrator authorization can request to view a
video preview.
• Video preview is supported with MPM+ and MPMx cards.
• Only one preview window can be displayed for each RMX Web
Client connection (workstation).
• Only one preview window can be displayed for a single conference
and up to four preview windows can be displayed for each media
card on different workstations (one per workstation and one per
conference).
For example, if the RMX contains two media cards, and there are 5
conferences running on the RMX, if five conferences are running on
the same media card, only four conferences can be previewed from
four different workstations. If four or less conferences are running on
