Well now that the FCC is talking SFNs and if as you say there were few
legacy receivers and most receivers could decode MPEG4 and MPEG2 and
receive most modulations then they could, might allow for numerous
modulations and MPEG2/MPEG4. As long as a broadcasters using another
modulation didn't interfere with another broadcaster because of such
use. Onus being on the broadcaster. LPTV stations seem to do just fine
under such limitations.
It seems logical to me that all receivers in the not too distant
future will do all modulations and all major codecs. An maybe even be
upgradeable.
It seems this would be logical from an inventory position for a
manufacturer in say China.
