Enhanced Video This option is applicable to standard Video cards and
is not required for participants connecting to
conferences running on the Video+ cards (the
VIdeo+ card provides the high quality video
combined with high Line Rates using one video
codec).
The MGC Manager can provide high quality video
(30 frames per second for incoming and outgoing
video streams) for line rates up to T1/ E1 in
Transcoding and Continuous Presence conferences.
This is done by allocating two video codecs to the
participant instead of one. One of the video codecs is
used for encoding, while the other is used for
decoding the incoming video stream.
Select this check box to enable the high quality video
feature for the participant.
Enhanced Video
(con’t)
Note:
• In a Video Switching conference, this field is
disabled.
• To work with 30 frames per second the High
Frame Rate flag in the system.cfg must be
enabled.
• To work with bit rates higher than 768 Kbps, the
High Bit Rate flag in the system.cfg must be
enabled.
• During an On Going ISDN/ATM/MPI connected
conference this setting may be greyed out.
AGC The Auto Gain Control mechanism regulates noise
and audio volume by keeping the received signal to
all participants balanced. Different endpoints and
phones produce different types of source noise and
volume. The Auto Gain Control mechanism can be
applied to all incoming audio streams prior to mixing,
thereby dynamically changing the amplification of the
input signal providing a constant output amplitude.
Select this check box to enable Auto Gain Control
(AGC) for the participant.
