Optimal Definition Profiles - Cisco TelePresence System Quick Set C20 Administrator's Manual

Cisco TelePresence System Quick Set C20 and Profiles using C20
Contents Introduction

Optimal definition profiles

Under ideal lighting conditions the bandwidth (call rate)
requirements can be substantially reduced.
The optimal definition profile should reflect the lighting
conditions in your room and the quality of the video input
(camera); the better the lighting conditions and video input, the
higher the profile. Then, in good lighting conditions, the video
encoder will provide better quality (higher resolution or frame
rate) for a given call rate.
In general, we recommend the optimal definition profile set to
Normal. However, if lighting conditions are good we recommend
that you test the endpoint on the various Optimal Definition
Profile settings before deciding on a profile.
Go to Advanced Configuration on the web interface and
navigate to Video > Input > Source [1..n] > OptimalDefinition >
Profile to select the preferred optimal definition profile.
You can set a resolution threshold below which the maximum
frame rate will be 30 fps.
Go to Advanced Configuration on the web interface and
navigate to Video > Input > Source [1..n] > OptimalDefinition >
Threshold60fps to set the threshold.
The video input quality settings must be set to Motion for the
optimal definition settings to take any effect. With the video input
quality set to Sharpness, the endpoint will transmit the highest
resolution possible, regardless of frame rate.
Go to Advanced Configuration on the web interface and
navigate to Video > Input > Source [1..n] > Quality
video quality parameter to Motion.
You can read more about the video settings in the
settings chapter.
