Administrator’s Guide for the Polycom RealPresence Group Series Call Speeds and Resolutions

Call Speeds and Resolutions
The following illustrations show the resolution and frame rate sent in a call, depending on the speed of the
call and the Optimized for setting of your Camera input. The values for sharpness and motion are the same
from 4 MB to 6 MB for systems that support higher call speeds.
The difference between NTSC and PAL cameras is how frame rates are calculated:
● NTSC 60 fps equals PAL 50 fps
● NTSC 30 fps equals PAL 25 fps
Table: Call Speeds and Resolutions in High Profile Calls on page 211 shows the resolutions for People video
on RealPresence Group systems with NTSC cameras in H.264 High Profile calls.

Group 700 only)

These values do not apply when the Lync Interoperability option is enabled, whether it is in
a Lync 2010 or Lync 2013 environment. When this option is enabled, all calls are CCCP
calls and are capped at 1.5 Mbps due to ICE restrictions.
