Description
Readout of the link margin. The link margin is calculated by subtracting
the modcod dependent margin from the estimated Eb/No in DVB-S or
Es/No in DVB-S2.
It indicates the receive margin before reaching the threshold point of quasi
error free operation (QEF) operation. The Eb/No for quasi error free
operation is taken from the DVB standards EN300421 and EN301210.
Basically it is the margin in dB that a signal can decrease in Eb/No before
errors will have noticeable effects on the output transport stream.
