The remaining transmission parameters are detected demodulating the
locked signal.
In case of a DVB-S2 signal, there will be some special settings for this
type of signal.
Physical Layer Scrambling or PLS is used in DVB-S2 as a way to improve
data integrity. A number called the "scrambling sequence index" is used
by the modulator as a master key to generate the uplink signal. This same
number must be known by the receiver so that demodulation is possible.
Most satellite transponders use PLS 0 as a default value but there are
some transponders that use other values.
If it is a multistream signal, it will appear an option that enables filtering
by the input stream identifier (ISI) and to select the stream to
demodulate.
