Parameters : It shows the TPS parameters (Transmission Parameters
Signalling) for the locked signal according to the modulation
standard. This option is available only when these
parameters are detected.
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. They are:
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.
In case of a Generic signal, the menu shows an option to select the signal
bandwidth.
