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.
