Default HD or BluRay?

And as for on-line delivery, It may well be ten years or
more before most people can regularly download a single
20GB+ movie!


I don't have any facts to refute you, but my "gut" tells
me this is way off-base. I would guess that "most" folks
(in the U.S.) have the ability
to download 20 GB more or less overnight right now [1],
and that the internet pipes are only going to grow bigger
over time.


The questionable presumption here is that it would always take 20 GB in
order to download a HD movie.

The size of lossy-compressed video files is shall we say, negotiable. ;-)

Is overnight, or even a couple of days, too long to wait?


I think the benchmark would be to download a movie in an amount of time
equal to its duration.

I don't think so - many folks wait two to four days to exchange a movie
from Netflix these days.


That would be a very relaxed standard, but one that might sell.

[1] The average cable modem download speed is around 4
Mb/s == 500 kB/s. Then


(20 GB) * (1 s / 500 kB) * (1E6 kB / GB) * (1 hour /
3600 s) = 11.1 hours


Back in the days when cable modems were unfettered by vendor performance
management, they could run at close to 10BT speeds - at least 1000 kB/sec.
Ah, those were the days!
