Setting Call Bandwidth in XT Series

About this task
You can set the maximum bandwidth used by the Avaya Scopia
a meeting, measured as the maximum bitrate.
Bitrate is the speed of data flow. Higher video resolutions require higher bitrates to ensure the
video is constantly updated, thereby maintaining smooth motion. If you lower the bitrate, you lower
the quality of the video. In some cases, you can select a lower bitrate without noticing a significant
drop in video quality; for example during a presentation or when a lecturer is speaking and there is
very little motion. Bitrate is often measured in kilobits per second (kbps).
The relationship between bandwidth and resolution dramatically changes when your call uses H.
264 High Profile. H.264 High Profile is a standard for compressing video by up to 25% over the H.
264 Baseline Profile, enabling high definition calls to be held over lower call speeds. If you change
the video quality setting to Sharpness, it can slightly change the bandwidth required to maintain
the same resolution. To change this setting, see
page 242.
