DVB-S2 is something you don't hear much about ... DVB-S2 allows MPEG-4 compression for HD and pilots to recover the signal during high noise conditions (rain fade).
Scott and/or others,

What are pilots in this context?

Thanks,
Dave

Pilots, or more correctly pilot symbols, consist of additional information which the receiver uses to help lock onto the carrier. That's a very simplified description....
Thanks Scott for the explanation and the link.

Its fun to learn about all this stuff.
