Enhanced Video | 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. |
| Note: |
| • 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. |
|
|
AGC | The Auto Gain Control (AGC) is the system |
| default. |
| Clear this check box to disable the Auto Gain |
| Control (AGC) for the participant. |
| 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. |
