Originally, the ATSC standard *did not* even include SDTV, so MPEG-2 MP@HL was 
mandatory. Even after SD was added, wisely enough, ATSC still mandated HD 
stream reception. So that, unless some sort of decimating feature was 
developed, MPEG-2 MP@HL would be mandatory regardless. Even if the image 
eventually went to an SD screen.

And that decimating feature was never developed. Why? Because the HL decoders 
became plenty cheap enough.

Just like DVB-T, DBS and cable were simply not forward-looking enough. And now 
all of them are stuck with having to support simulcast streams. But not OTA!

As I said back then, that was a mistake. For DVB-T, excusable given their 
history with HD-MAC. For DBS, maybe, given their spectrum issues? Not sure 
about that. For cable? No excuse. They were just dead set against ATSC.

May I instead use myself as the market average case?

I bought my first LCD HDTV in late 2003 or early 2004. I had a DVD player, but 
like (virtually) all DVD players from the years before then, this one had no 
component outputs. So I used, IIRC, S-video.

However, there was no question why I bought the HDTV set. It was in 
anticipation for the time when the CE companies would FINALLY provide a 5th gen 
ATSC STB. I got sick and tired of waiting, so in 2005 I bought an Accurian 3rd 
gen, quite decent STB. And then a few weeks later a second similar one, for our 
upstairs setup. (And since then, upgraded both systems to integrated sets.)

So yes, we did have DVD on HDTV sets before real HD content, but that's hardly 
why we bought them. We bought them for watching HD content as it was meant to 
be seen.
