Great for Australia. That experience would most likely not be repeated
here, no matter what RF modulation standard is used.
If high performance and low cost ATSC receivers are being kept from the
market, by whatever forces and for whatever reasons, there's absolutely
no reason to believe that a different modulation scheme would change
matters.
If you believe in a conspiracy of cable and DBS vendors (which I don't
but just humor me a a second), I would suggest that they would work that
much harder to keep COFDM boxes out of the market than they have done
with ATSC.
FWIW, I'm fully enjoying my DTT at this time. Looking forward to
watching the Olympics in HDTV. And optimistic that the dam will soon
burst, if for no other reason than the March 2007 date for ATSC
inclusion in all TV sets and recording devices.

Over here, without any govt HD mandate, I receive 13 multiplexes, Ian,
each one of which transmits HD much of the time. Craig says that many of
these are duplicates much of the day? True, but I get at least seven
multiplexes today, and hopefully nine in the near future, that are not
duplicates. So again, there's no shortage of channels, compared with any
other DTT system in the world. Not only that, but the HD doesn't need to
be simulcast, because all receivers can decode the HD stream. So we
don't waste a multicast just to transmit the HD program.
My wife does make a good point, though. She says that possibly ATSC lost
momentum when the early receivers were so bad. That makes more sense to
me than conspiracy theories. I would hope that momentum could be
regained with the 4th and 5th gen stuff out there, but we'll see.
And finally, there is no technical reason why every single Aussie DVB-T
STB cannot be sold in the US, in ATSC livery. None.
