Polycom 1500/1800/2000/4000 manual Workstation Requirements to Display Video Preview

Additional Conferencing Information

●All users can view a video preview.

●Only one preview window can be displayed for each Collaboration Server 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 Collaboration Server contains two media cards, and there are 5 conferences running on the Collaboration Server, 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 supported with H.264 High Profile.

●Video Preview is not supported for endpoints using the RTV protocol.

●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 Polycom Desktop application (such as CMAD) window cannot be open and running simultaneously on the same PC as both require the same DirectDraw resource.
