We can achieve that and much more already, and with easier reception in
many cases than Europeans have. The problem there is power restrictions.
But as Craig already pointed out, broadcasters here prefer to depend on
cable and DBS carriage. In Gainesville, they opted not to install
translators. The closest NBC affiliate is 80 miles away.

Is that successful in any successful DVB-T market? (Not to say it
couldn't be done. And by the way I read in TPV that Moviebeam is
shifting to ATSC. And A-VSB is now available for robust streams.)

I always get non-real-time ATSC content delivered to my TV set, Bob, but
Craig says broadcasters don't want to do it this way. They want me on

On non-real-time: *Any* content you record is consumed non-real-time. It
can be transmitted at any speed you want, slower or faster than real
time, or real time, to a storage device. The faster you stream it, the
more bandwidth it takes, so there's no free lunch.

No it wouldn't. Ask Craig. He'll tell you.
