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

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

Optimal definition profiles

Under ideal lighting conditions the bandwidth requirements can
be substantially reduced with the optimal definitions profiles.
Generally, we recommend the Optimal Definition set at Normal.
If lighting conditions are good we recommend that you test
the endpoint on the various Optimal Definition settings before
deciding on a profile.
Go to Advanced configuration (menu on screen or web
interface) to set the optimal definition profile:
• Navigate to Video > Input > Source [1..n] > OptimalDefinition
> Profile and select a profile.
You can set a resolution threshold below which the maximum
frame rate will be 30 fps.
Go to Advanced configuration (menu on screen or web
interface) to set the threshold:
• Navigate to Video > Input > Source [1..n] > OptimalDefinition
> Threshold60fps and select a threshold.
The video input quality settings must be set to Motion to ensure
the Optimal Definition to work. With the video input quality set
to Sharpness, the endpoint will transmit the highest resolution
possible, regardless of frame rate.
Go to Advanced configuration (menu on screen or web
interface) to set the input quality:
• Navigate to Video > Input > Source [1..n] > Quality
the video quality parameter.
You can read more about the video settings in the
settings chapter.
