Forward Error Correction (FEC) is a proactive method of sending redundant
information in the video stream to preempt quality degradation. FEC
identifies the key frames in the video stream that should be protected by
FEC. There are several variants of the FEC algorithm. The Reed-Solomon
algorithm (FEC-RS) sends redundant packets per block of information,
enabling the sender (like the Scopia
percent packet loss in the video stream with minimal impact on the
smoothness and quality of the video.
Far End Camera Control (FECC) is a feature of endpoint cameras, where
the camera can be controlled remotely by another endpoint in the call.
See FEC on page 204.

See Frames Per Second
Frames Per Second (fps), also known as the frame rate, is a key measure
in video quality, describing the number of image updates per second. The
average human eye can register up to 50 frames per second. The higher
the frame rate, the smoother the video.
Full HD, or Full High Definition, also known as 1080p, describes a video
resolution of 1920 x 1080 pixels.
The full screen view shows one video image. Typically, it displays the
remote presentation, or, if there is no presentation, it displays the other
meeting participant(s).
A gatekeeper routes audio and video H.323 calls by resolving dial strings
(H.323 alias or URI) into the IP address of an endpoint, and handles the
initial connection of calls. Gatekeepers also implement the dial plan of an
organization by routing H.323 calls depending on their dial prefixes.

Scopia Management includes a built-in Avaya Scopia
ECS is a standalone gatekeeper.
A gateway is a component in a video solution which routes information
between two subnets or acts as a translator between different protocols.
For example, a gateway can route data between the headquarters and a
partner site, or between two protocols like the TIP Gateway, or the Scopia
100 Gateway.
GLAN, or gigabit LAN, is the name of the network port on the XT Series. It
is used on the XT Series to identify a 10/100/1000MBit ethernet port.
