Video Protocols and Resolution
Configuration for CP Conferencing
Video Resolutions in AVC-based CP Conferencing
The RealPresence Collaboration Server (RMX) 1500/1800/2000/4000 always attempts to connect to
endpoints at the highest line rate defined for the conference. If the connection cannot be established using
the conference line rate, the Collaboration Server attempts to connect at the next highest line rate at its
highest supported resolution.
Depending on the line rate, the Collaboration Server sends video at the best possible resolution supported
by the endpoint regardless of the resolution received from the endpoint.
The video resolution is also defined by the Video Quality settings in the Profile.
Motion, when selected, results in lower video resolution at higher frame rates (30 fps to 60 fps).
Sharpness, when selected, results in higher video resolution at lower frame rate (30 fps and lower).
However, it can also be sent in 1080P 60fps.
The combination of frame rate and resolution affects the number of video resources required on the MCU
to support the call.
The following resolutions are supported:
Video Display with CIF, SD and HD Video Connections
Although any combination of CIF, SD and HD connections is supported in all CP conferences, the following
rules apply:
The following video resolution information applies to AVC CP Conferencing Mode. For a description
of resolutions for SVC Conferencing Mode see Defining SVC Conference Profiles.
