Video Protocols and Resolution Configuration for CP Conferencing

Resolution Configuration for CP Conferences
The Resolution Configuration dialog box enables you to override the default video resolution decision
matrix, effectively creating your own decision matrix. The minimum threshold line rates at which endpoints
are connected at the various video resolutions can be optimized by adjusting the resolution sliders.
System resource usage is also affected by the Resolution Configuration settings.
For more information see Video Resource Usage and Default Minimum Threshold Line Rates and Resource
Usage Summary.
Guidelines
● Resolution Slider settings affect all Continuous Presence (CP) conferences running on the
Collaboration Server. Video Switched conferences are not affected.
● A system restart is not needed after changing the Resolution Slider settings.
● Resolution Slider settings cannot be changed if there are ongoing conferences running on the
Collaboration Server. The displayed sliders and the resolutions change according the MCU type.
Modifying the Resolution Configuration
The Resolution Configuration dialog box is accessed by clicking Setup > Resolution Configuration in
the Collaboration Server Setup menu.
Clicking the Detailed Configuration button toggles the display of the Detailed Configuration pane, which
displays sliders for modifying minimum connection threshold line rates for endpoints that support H.264
Base Profile or High Profile. The Detailed Configuration pane can also be opened by clicking the Manual
radio button in the Resolution Configuration pane.
Sharpness and Motion settings are accessed by clicking the Sharpness and Motion tabs when the
Detailed Configuration is open.

On the RealPresence Collaboration Server (RMX) 1500 MPMx-Q assembly, the use of HD with
Continuous Presence requires an additional license. In the Resource Report and Resolution
Configuration panes, HD settings are displayed but are not enabled and if HD is selected the system
will enable SD by default.
