I can't think of a better/clearer structure than this - I've put an example up
on the wiki:
Now however, the multiplex differentiators are the problem (for distinguishing
between transponders with the same IDs). Does anyone have any suggestions as
to good numbers to use?
Obviously they have to be based on the frequency somehow, but they also have
to take into account tuning varaiations between people's systems (e.g.
different LNB drifts).
The first thing that springs to my mind is something like the following:
DVBS: ((frequency / (symbolrate/1000)) << 1) | polarisation
DVBT: (frequency / bandwidth)
DVBC: (frequency / symbolrate)
A naive implementation
