The feds are going to provide ATSC to NTSC converters free (cough
cough) of cost to the poor.

Cable and dish are a big part of the market. It isn't clear to me if
the feds are going to mandate that HD be delivered over those services.
Even if they feds do mandate HD to subscribers, there is cash flow to
recover the cost of new set top boxes.

The feds are not even mandating HD on OTA stations. As far as I can see,
most programming on DTV stations is in low res format (720i?) And I'm not
impressed in the least, analog looks much better (we're stuck with digital
satellite feed for our US/English content, and it looks like total garbage).

I think 720p is a minimum and it's 4x the resolution of NTSC. Going
from 720p to 1080i isn't that much of a difference, though you notice
the difference in a side by side comparison.

May be 4x the resolution of a VHS VCR (but not even quite that, at SP speed
most get 270 lines), but not quite twice what regular broadcast NTSC
resolution is. And NTSC STILL looks better because there's no artifacting
in it, and no pixelization. Our satellite feed is so bad you can see
artifacts in it every time there is a rapid pan or sweep, and when you have
color gradients, you can see large amounts of pixelization in the
transitions. I'll keep my analog, thanks, even if that means never watching
OTA TV again.

I think it is interesting that you bring up a similar point about
digital video that I have been expousing about radio digital audio.

It's all about trying to cram a digital signal bandwidth and digitized
signal resolution in an analog spectrum space. This not unlike trying to
put a square peg in a round hole. You can do it but the results are not
pretty.
