An unbalanced microphone uses a cable that is not especially built to
reduce interference when the cable is long. As a result, these unbalanced
line devices must have shorter cables to avoid audio disruptions.
Unicast streaming sends a separate stream of a videoconference to each
viewer. This is the default method of streaming in Scopia
To save bandwidth, consider multicast streaming.
URI is an address format used to locate a device on a network, where the
address consists of the endpoint's name or number, followed by the domain
name of the server to which the endpoint is registered. For
example,<endpoint name>@<server_domain_name>. When dialing URI
between organizations, the server might often be the Avaya Scopia
PathFinder server of the organization.

See Video Fast Update (VFU)
VGA defines a video resolution of 640 x 480 pixels.
Video Fast Update (VFU) is a request for a refreshed video frame, sent
when the received video is corrupted by packet loss. In response to a VFU
request, the broadcasting endpoint sends a new intra-frame to serve as the
baseline for the ongoing video stream.
A video layout is the arrangement of participant images as they appear on
the monitor in a videoconference. If the meeting includes a presentation, a
layout can also refer to the arrangement of the presentation image together
with the meeting participants.
See Resolution on page 210.
See Switched video on page 213.
A videoconference is a meeting of more than two participants with audio
and video using endpoints. Professional videoconferencing systems can
handle many participants in single meetings, and multiple simultaneous
meetings, with a wide interoperability score to enable a wide variety of
endpoints to join the same videoconference. Typically you can also share
PC content, like presentations, to other participants.
