/* According to ETSI EN 302 307 5.5.4 the PLS (Physical Layer
Scrambling) for DVB-S2 consists of a complex randomization
sequence which is ultimately derived from two recursively
defined m-sequences (=MLS or maximum length sequences)
x(i) and y(i) of polynomials over GF(2) with m=18
(thus their length is 2^18 - 1).
These m-sequences with sequence y starting from y(0) and
sequence x starting from x(n) are combined to form a set
of 2^18 - 1 different Gold code sequences.
This starting number n of sequence x selects which
of those 2^18 - 1 Gold code sequences to use.
As a DVB-S2 tuning parameter n is called the scrambling sequence index
(cf. ETSI EN 300 468 table 41) or Gold sequence index,
commonly also just called "Gold code".
The 18 values of the sequence x starting from x(n)
(x(n) ... x(n+17)) are also called the "Root code".
So, Gold and Root codes are not different ways of PLS, they are
just different ways to select the same sequence start point.
The initial values for x(i), i=0..18 are x(0)=1, x(1)=0, .., x(17)=0 .
The polynomial used for the x sequence recursion is 1+x^7+x^18.
If the lower 18 bits of a variable "uint32_t X" contain x(n) ... x(n+17),
then we can simply calculate x(n+1) ... x(n+18) by doing:
X = (((X ^ (X >> 7)) & 1) << 17) | (X >> 1);
So, if X contained the "Root code" corresponding to "Gold code" n,
it will now contain the "Root code" corresponding to "Gold code" (n+1).
Note that X=0 and n=2^18 - 1 do not exist (or rather the lattter is the same
as n = 0) and for n=0 to 2^18 - 2 and X=1 to 2^18 - 1 there is a
one-to-one correspondence (bijection).
Note that PLS has nothing to do with encryption for DRM purposes. It is used
to minimize interference between transponders.
"Combo code":
There is no such thing as a combo code. It is the result of a bug in older
STV090x drivers which resulted in a crazy race condition between a Gold->Root
conversion in the STV and an ongoing I2C write.
Better forget about it and determine the proper Root or Gold code.
