Video Protocols and Resolution Configuration for CP Conferencing
Polycom®, Inc. 95
●Base Profile - Endpoints that do not support H.264 High Profile connect at these minimum threshold
bit rates.
●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 HD720p30 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.
