Variable Coding and Modulation (VCM) (Used in the HRD-106 and
IRD-70)
Variable Coding and Modulation is a mode of operation that allows different
modulation parameters to be applied to the different DVB-S2 streams of a
multistream signal. If each of the streams are intended for a different
receiving site, VCM allows optimizing the parameters of each stream to get
the best performance for each receive station, instead of dimensioning the
whole link according to the smallest station.

Adaptive Coding and Modulation (ACM) (Used in the HRD-106 and
IRD-70)
In Adaptive Coding and Modulation mode, the modulation parameters of the
Baseband frames can vary over time, according to the instantaneous
receiving conditions of the site where the frame will be received. In ACM there
is a feedback mechanism between the demodulator and the modulator. This
feedback mechanism dynamically tells the modulator which modulation
parameters to use for each baseband frame. ACM allows operating satellite
links with almost no margin, since the system adapts automatically to fading
or interference conditions.
