The following displays the transport and audio default C/N Margin relationships:
Transport Default C/N Margin Relationship
DVB-S/DVB-S2
Audio Mute
-5.0 to 20.0
dB
This is used to set the Audio channel
Cutoff and Restore C/N margin values
(limits) to mute audio when the signal
quality is severely degraded when using
DVB-S or DVB-S2 modulation.
The Cut Off is the lower limit for the audio
C/N margin setting. Audio will be muted
when the C/N margin is below the Cutoff
setting for a nominal delay of 4 seconds.
The delay is between the time the
condition is first detected and the time the
transport is muted.
0.0
DVB-S/DVB-S2
Audio Restore
-5.0 to 20.0
dB
This is used to set the Audio channel
Cutoff and Restore C/N margin values
(limits) to mute audio when the signal
quality is severely degraded when using
DVB-S or DVB-S2 modulation.
The Restore is the upper limit for the
audio C/N margin setting. Audio will be
un-muted (e.g., restored) when the C/N
margin rises above the Restore setting for
a nominal delay of 8 seconds. The delay is
between the time the condition is first
detected and the time the transport is
restored.
