The Maximum CP Resolution of the Collaboration Server can be set to one of the following resolutions:

● HD 1080p60
● HD 1080p30
● HD 720p30
● SD 30
● CIF 30

The MINIMUM_FRAME_RATE_THRESHOLD_FOR_SD System Flag can be added and set to prevent low 
quality, low frame rate video from being sent to endpoints by ensuring that an SD channel is not opened at 
frame rates below the specified value. For more information see 

.

For systems containing MPM Rx cards, the LIMIT_SD_AND_CIF_BW_MPMRX System Flag, when added 
to system.cfg and set to YES (default), limits the maximum negotiated and opened bit rate for resolutions 
equal or lower than SD to 1Mbps. When set to NO no limitation is applicable to SD and CIF bit rates.

The following higher video quality resolutions are available with when the Collaboration Server is working 
in MPMx Mode:

CIF

352 x 288 pixels

at 50 fps.

WCIF

512 x 288 pixels

at 50 fps

WSD

848 x 480 pixels

at 50 fps

W4CIF

1024 x 576 pixels

at 30 fps

HD 720p

1280 x 720 pixels

at 60 fps (symmetric with MPMx)

HD 1080p

1920 x 1080 pixels

at 30 fps (symmetric with MPMx)

HD 1080p

1920 x 1080 pixels

at 60 fps (asymmetric with MPMx)

The video resolution transmitted to any endpoint is determined by the endpoint’s capabilities, the 
conference line rate, the Conference Profile’s Motion and Sharpness settings and the Collaboration 
Server’s Card Configuration Mode (MPMx or MPMRx).
