Setting Call Bandwidth in XT Series
About this task
You can set the maximum bandwidth used by the Avaya Scopia
®
XT Series when participating in 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. In video recordings, the bitrate determines the file size for each minute of recording.
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. It requires both
sides of the transmission (sending and receiving endpoints) to support this protocol. 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
Resolving Lip Sync Problem on page 191.
