Click on MPEG2 at the left menu, scroll down to the 4.2.2 section.

Another thanks from me, turbosat, lots of acronyms/terms there that I have been wanting good explanations for, bookmarked. :up

Glad it helped. Some of it I have read and re-read, still have trouble digesting it!

I found the modulation section really interesting, its a good read if you want to understand the differences between qpsk and 8psk and different fec and how they effect bandwidth etc.
