• Video Quality Optimized
Video is optimized through higher resolution connections at lower line rates increasing
the resource usage at lower line rates. This may decrease the number of participant
connections.
The Video Quality Optimized settings are described in the section: "The CP Resolution
Decision Matrix” on page 3-4.
• Manual
The administrator adjusts the sliders to accommodate local conferencing requirements.
Sharpness / Motion Resolution Slider Panes
Sharpness and Motion are Video Quality settings that 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 according to the selection of Sharpness or Motion. The
resolution matrix for Sharpness or Motion 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 1.5 system resources instead of 3
system resources.
•Moving the HD1080p30 resolution slider from 4096kbps to 2560kbps decreases the
minimum connection threshold line rate for that resolution. Endpoints connecting at
line rates between 2560kbps and 4096kbps that would have connected at
HD 720p30 resolution will instead connect at HD 1080p30 resolution. Each of the
affected endpoints will connect at higher resolution but will use 6 system resources
instead of 3 system resources.
Use this option when the priority is to use higher video resolutions while decreasing the number of
participant connections.
