I used to have a better document that outlines the modulations schemes 
for the different
Digital Television broadcast standards, but I seem to have lost it.  
This document seems
to get the job done however.

    As a side note any one interested in modulation, decoding, and 
transport stream
capture/transmission hardware should check out:
    
    http://www.computermodules.com

    These guys sell all kinds of hardware that should be useful to 
European and American
users (they sell both DVB and ATSC/SMPTE hardware).
