Description
Select the video compression standard that will be
forced by the MCU on the endpoint when connecting
to the conference: H.261, H.263, H.264 or RTV.
Select Auto to let the MCU select the video protocol
according to the endpoint's capabilities.
The Auto check box is automatically selected to use
the Resolution defined for the conference.
To specify the Resolution for the participant, select
the required resolution from the drop-down menu.
To adjust the volume the participant broadcasts to the
conference or the volume the participant hears the
conference, move the slider; each unit represents an
increase or decrease of 3 dB (decibel). The volume
scale is from 1 to 10, where 1 is the weakest and 10
is the strongest. The default connection value is 5.
Select whether the endpoint uses encryption for its
connection to the conference.
Auto (default setting) indicates that the endpoint will
connect according to the conference encryption
setting.
AGC (Auto Gain Control) mechanism regulates noise
and audio volume by keeping the received audio
signals of all participants balanced. Select this check
box to enable the AGC mechanism for participants
with weaker audio signals.
Notes:
• To be enable AGC, set the value of the
ENABLE_AGC System Flag in system.cfg to be
YES. The flag's default value is NO.
• If the System Flag does not exist in the system, it
must be manually added to the System
Configuration. For more information see
"Modifying System Flags" on page 19-6.
•
Enabling AGC may result in amplification of
background noise.
