Chapter 4-Video Protocols and Resolution Configuration for CP Conferencing
Polycom, Inc. 4-11
• High Profile - Endpoints that support H.264 High Profile connect at these minimum
threshold bit rates.
Although the default minimum threshold bit rates provide acceptable video quality, the
use of higher bit rates usually results in better video quality.
These Video Quality settings are selected per conference and are defined in the conference
Profile and they determine the resolution matrix that will be applied globally to all
conferences. The resolution matrix is determined by the resolution configuration and can be
viewed in the Resolution Configuration sliders.
System Resource usage is affected by the Resolution Configuration settings.
Example
As shown in following diagram:
•Moving the HD720p30 resolution slider from 1024kbps to 1920kbps increases the
minimum connection threshold line rate for that resolution. Endpoints connecting at
line rates between 1024kbps and 1920kbps that would have connected at HD 720p30
resolution will instead connect at SD 30 resolution. Each of the affected endpoints will
connect at lower resolution but will use 1 system resource instead of 2 system resources.
