Description
The RealPresence Collaboration Server offers different types indicators and
allows you to design the layout of those indicators on some participant's
screens:
•
Network Quality — Indicates the quality of the video channels
•
Recording — Indicates that the system is recording the conference
•
Audio and Video Participants — Identifies the number of audio and video
participants in the conference (AVC only)
The RealPresence Collaboration Server enables you to define a single cell in
the conference layout to cycle the display of participants that aren't in the
conference layout.
Polycom Lost Packet Recovery (LPR) and Dynamic Bandwidth Allocation
(DBA) help minimize media quality degradation that can result from packet loss
in the network.
The Polycom LPR algorithm uses Forward Error Correction (FEC) to create
additional packets that contain recovery information. DBA allocates the
bandwidth needed to transmit the additional packets.
Lecture Mode enables all participants to view the lecturer in full screen while
the conference lecturer sees all the other conference participants in the
selected layout. When the number of sites or endpoints exceeds the number of
video windows in the layout, the system switches among participants every 15
seconds.
The RealPresence Collaboration Server automatically detects and mutes AVC
endpoints that have a noisy audio channel.
