Interesting points. You do seem to put a lot of weight on the potentially
negative impact the ATSC itself has on this sordid state of affairs. I'm not
sure that's entirely warranted.
To keep this as precisely comparable as possible, what makes Australian DTT
successful is already doable with ATSC as is. No need to rely on the ATSC
being overly clever about implementing E-VSB or A-VSB, for example. And the
Aussies stuck with 64-QAM, same as us (well, equivalent to us).
And yet, even when nothing of extraordinary insight is being asked of
anyone, hardware is still not available. I understand your points about
DVB-T hardware theoretically being harder to stop, but there's no reason in
the world to believe that plain old A/53 hardware should have been easy to
block either. For the basics, we don't need anything new. And the basics is
all any other country is using for their FOTA TV, for the time being.
Why aren't plain old 4th/5th gen ATSC STBs, PVRs, and DVDRs positively
oozing out of China? Available for direct purchase on web sites?
So I have a lot of faith that DVB-T hardware would also be blocked. The
salesmen would simply be telling us that there's no demand for DTT hardware
(adjusted for US 6 MHz channels), and you wouldn't see anything in stock.
Another parenthetical point is that some text in ATSC documents is just
policy statements, I believe. Like the business quoted by John Shutt. To me,
those are easily changed with the stroke of a pen.
For instance, IIRC, A/90 included some policy statement that any broadcast
TV streams would have to use MPEG-2 compression. But that wasn't a technical
limitation of A/90, just a policy statement, which was obsoleted with the
draft standards for AVC and VC-1. As far as I can tell.
