I won't dispute that back in 2001, when the decision
on RF standards was up in the air, everything came to
a halt. But that's a long time ago. And as we have
discussed here, the NAB at the time did not go for a
known quantity, COFDM, but preferred to wait on the
unknown, i.e. the improvement of 8-VSB. And the FCC
went along with the NAB.
Okay, fine. That's water under the bridge. In April
of 2002, the CRC published the test results of the
Linx 4th generation receiver. Then came field tests
of that receiver, by Linx and by the CRC. In
September 2003 the CRC published the test results of
the Zenith/LG 5th gen receiver.
So here we had indications that a properly
functioning suppressed carrier scheme could be
designed, with the advantages in spectrum efficiency
and power that have been well known to radio
engineers since the 1920s, and certainly by the
1930s.
I'd say by then at least, the broadcasters should
have had enough rekindled interest to occasionally
mention their DTT streams? Other than the HDTV banner
at the beginning of prime time shows, I see nothing
about the transition, from broadcasters. Nada.
Two days ago, I happened to be browsing around a
Target store before the movie started. I looked at
the TV section. No mention of ATSC. I looked at the
DVDRs for sale. Only NTSC tuners built in. This is
crazy. The DTT transition is still a best kept
secret.
The market demand for DTT is supposed to be created
by the broadcasters. I would expect the retailers to
*respond* to this market demand, not to create the
demand on behalf of broadcasters. Broadcasters should
go in assuming that retailers are clueless.
