System resource usage is optimized by allowing high resolution connections only at
high line rates and may result in lower video resolutions (in comparison to other
resolution configurations) for some line rates.
The
Resource Optimized
settings are described in the section
:
"
Default Minimum Threshold
Line Rates and Resource Usage Summary”
on page
3-12
.
•
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 V
ideo Quality Optimized
settings are described in the section
:
"
Default Minimum
Threshold Line Rates and Resource Usage Summary”
on page
3-12
.
•
Manual
Manually adjusting the sliders to accommodate local conferencing requirements.
Resolution Configuration - Detailed
H.264 High Profile
allows higher quality video to be transmitted at lower bit rates.
However, setting minimum bit rate thresholds that are lower than the default may affect the
video quality of endpoints that do not support the
H.264 High Profile
. The RMX uses two
decision matrices (
Base Profile
,
High Profile)
to enable endpoints to connect according to their
capabilities.
Sharpness and Motion
Sharpness
and
Motion
are
Video Quality
settings that are selected per conference and are
defined in the conference
Profile.
A conference with
Sharpness
selected in its
Profile
uses the
Sharpness
settings
of the
Resolution Configuration
and a conference with
Motion
selected in its
Profile
uses the
Motion
settings
of the
Resolution Configuration
dialog box.
The
Sharpness
and
Motion
tabs in the
Resolution Configuration
dialog box allow you to view
and modify
Resolution Configuration
settings for conferences with either
Video Quality
setting.
Resolution Configuration Sliders
The
Detailed Configuration
dialog box allows you to configure minimum connection
threshold bit rates for endpoints that support
H.264 High Profile
and those that do not
support
H.264 High Profile
by using the following slider panes:
Use this option when the priority is to save MCU resources and increase the number of participant
connections.
Use this option when the priority is to use higher video resolutions while decreasing the number of
participant connections.
