which enhance resolution, frame rate and quality. Each additional layer is
only transmitted when bandwidth permits. This allows for a steady video
transmission when available bandwidth varies, providing better quality
when the bandwidth is high, and adequate quality when available
bandwidth is poor.
SVGA
SVGA defines a video resolution of 800 x 600 pixels.
Switched video Switching is the process of redirecting video as-is without transcoding, so
you see only one endpoint's image at a time, usually the active speaker,
without any video layouts or continuous presence (CP). Using video
switching increases the port capacity of the Scopia
®
Elite MCU only by four
times.
Important:
Use switched video only when all endpoints participating in the
videoconference support the same resolution. If a network experiences
high packet loss, switched video might not be displayed properly for all
endpoints in the videoconference.
SXGA
SXGA defines a video resolution of 1280 x 1024 pixels.
Telepresence A telepresence system combines two or more endpoints together to create
a wider image, simulating the experience of participants being present in
the same room. Telepresence systems always designate one of the
endpoints as the primary monitor/camera/codec unit, while the remainder
are defined as auxiliary or secondary endpoints. This ensures that you can
issue commands via a remote control to a single codec base which leads
and controls the others to work together as a single telepresence endpoint.
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).
