Chapter 11 - Managing Participant Templates

Option | Description |
|
|
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 | Note: |
(con’t) | • 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. |
