I don't want to get into a discussion of what M/H TV would be (or should
be) used for, but my guess is that it will not be just to replicate the
"main" feed more robustly. Maybe just the audio, but I digress/linger
here.
If we had DVB-T here in the US, I bet I wouldn't have OTA television at
my house (40-50 miles from the New York canyons.) Certainly not from at
least three markets, as I do now with "big stick" ATSC transmission. It
would work at my desk in Midtown (big deal, I don't watch TV there if I
can avoid it, but with current receivers, it even works there.) I don't
see stations in a position to build a repeater system to serve "rural"
viewers. One of the network O&O station has a permit for a repeater,
but hasn't built it yet. It would seem prohibitively expensive to
expand coverage by even 10 miles all around the coverage area.
Back in the day, the head end for my local cable company had their
antennas even farther away from town than I do. It's a moot point now
because it was bought by an MSO and is probably fed by some OC-whatever
link from their main system.
COFDM makes sense for some applications, like ENG operations. It would
probably work great on something like the NYC Marathon, but last time I
checked, it looked like they were still using analog. (At least the
video from the motorcycles broke up in the same places it did when they
were using analog FM.) Maybe that will change this year.
I don't think broadcasters are planning to use M/H to improve robustness
on their main feeds. Cable filled that "niche" decades ago, and has
moved on to deliver other things. I expect broadcasters will also do
"other things" with their M/H systems.
One last thing: Content downloaded, side loaded, or broadcast to a
phone or other mobile device doesn't *have* to be watched on that
device. I've seen 720p video with 5.1-channel audio. It could
happen... ;)
Regards,
Ken

Most people also had smaller screens back then, too.

Re-read the last part of my sentence, Bert. As even you should know by
now, we should have had DVB-T here in 2000.
