Video Preview; Video Preview Guidelines - Polycom RMX 1500 Administrator's Manual

Video Preview

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.
In versions up to and including Version 7.2.2, only users with Administrator
authorization could 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 one media card and the remaining conferences are running
on the other media card, all five conferences can be previewed.
Live video that is shown in the preview window does not include the Content when it
is sent by the participant.
Video Preview is supported in cascaded conferences.
If the video preview window is opened when the IVR slide is displayed to the
participant, it will also be displayed in the video preview window.
Video Preview is not supported in RMX Manager application.
Video Preview is not supported with H.264 High Profile
Video Preview is not supported for RTV endpoints.
Video Preview is disabled in encrypted conferences.
Video preview cannot be displayed when the participant's video is suspended.
Participant's video preview and the CMAD window cannot be open and running
simultaneously on the same PC as both require the same DirectDraw resource.
