[opendtv] Re: Frames Per Second of 720P

Yeah, I just don't see that as being what M/H really becomes.  Entirely
possible, however.  But, the report made the assumption that N/H wouldn't
work in home receivers.

The statement by the authors assumes that programming in the M/H channel is 
simply a simulcast of programming in the main channel.  If this were the 
case, then this could also provide a low quality 'graceful degradation' for 
fixed receivers as well.
