Telepresence - Dual
row telepresence
room
Dual row telepresence rooms are large telepresence rooms with two rows
of tables that can host up to 18 participants.
TLS
TLS enables network devices to communicate securely using certificates, to
provide authentication of the devices and encryption of the communication
between them.
Transcoding
Transcoding is the process of converting video into different sizes,
resolutions or formats. This enables multiple video streams to be combined
into one view, enabling continuous presence, as in a typical
videoconferencing window.
UC (Unified
Communications)
UC, or unified communications deployments offer solutions covering a wide
range of communication channels. These include audio (voice), video, text
(IM or chat), data sharing (presentations), whiteboard sharing (interactive
annotations on shared data).
Unbalanced
Microphone
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
Unicast streaming sends a separate stream of a videoconference to each
viewer. This is the default method of streaming in Scopia
®
Desktop server.
To save bandwidth, consider multicast streaming.
URI
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.

User profile
A user profile is a set of capabilities or parameter values which can be
assigned to a user. This includes available meeting types (services),
access to Scopia
®
Desktop and Scopia

Mobile functionality, and allowed
bandwidth for calls.

VGA
VGA defines a video resolution of 640 x 480 pixels.
Video Fast Update
(VFU)
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.
