I agree with the first part. Another enhancement would be a more
efficient codec. We'll see how this plays out, as the March 2007 date
approaches and ATSC becomes more ubiquitous.
As to how widely implemented any new parts of ATSC will become, I
suppose that depends almost entirely on consumer demand for the new
services. For example, ATSC as is would have been more in demand if
there were some specific reason for people to buy it. Other than just
prettier pictures and nicer audio, which is enough reason for me, but
apparently not reason enough for everyone.
Cable demand was created by specific program offerings such as ESPN and
HBO, and even Nickelodian. Terrestrial broadcasters haven't yet offered
something analogous to these programs, i.e. something that is only
available over DTT. Actually, PBS is doing a decent job of that, IMO,
but not any of the others. I like the PBS -2 channel. It is a real
alternative with real programs.
Contrary to the impression some on this list continue to have, people
didn't rush off and subscribe to cable TV because they liked the coax
copper cable coming into their house, or the way video was modulated on
it, or the monthly fee. Ditto for DBS. The "modulation standard" isn't
what attracted customers, and certainly its robustness isn't anything to
brag about either.
Also, there's nothing inherently bad with the A/81 standard that I can
tell. It seems to accept everything, including DVB and DVB-SI. If it's
not implemented, because DirecTV and Echostar went their own way, I
would not conclude that those proprietary standards are any better than
A/81.
