Don't forget that I'm still using under 2 Mb/s for this.
And enjoying the level of quality commensurate with that bit rate.
Not saying this is ample, but surely 5+ Mb/s is ample.
Netflix SuperHD uses 6 Mbps. Sports needs a lot more. And that's just to
support ONE stream. Cox is running commercials here showing a kid using a
laptop, while dad and friends are watching multiple football games, some MPEG-2
TS streams and some via the Internet. It's not hard to eat up 25 Mbps.
So those who insist on multiple simultaneous high quality HD streams would
work to move that average figure down to 300, while those who are satisfied
with fewer simultaneous high quality HD streams would move the average up,
even way up.
Those who do not want at least 15 Mbps ( the lowest level of broadband Cox
offers in Gainesville) would likely choose DSL service from AT&T.

Yes, some of the DBS subscribers buy broadband from the cable
In urban and suburban areas, they likely buy their broadband already, either
from cable or from telco systems. So that's pretty much covered. Those who
have no access to broadband now tend to be in rural communities, and there
are, or there can be, different options for them. For rural homes, satellite
broadband is already available, and terrestrial WISPs either exist or are
being set up.
Missed it again.
DBS subscribers are doing the heavy lifting of TV via satellite. No doubt some
are also subscribed to Netflix, and may use other OTT services. But we are
talking about turning off the MVPD streams and moving everyone to the Internet.
That's nearly 40 million additional homes that will need broadband, or will
significantly INCREASE their use of broadband over current levels.
The infrastructure is mostly already in place. For example, I can get either
Cox or FiOS any time I want. The transition can happen more rapidly than you
think. And over and above any of these considerations, repurposing the cable
broadcast spectrum to broadband or "wideband" can only HELP solve this
problem.
Yup, most of us have access to the level of broadband service we would need to
move exclusively to OTT TV. But most of us still use FOTA or a MVPD service to
access most of the TV watched in the U.S. This is changing, albeit much slower
than you claim.
The distribution oligopolies are upgrading at the pace they need to keep up.
And they are benefitting by leveraging their sunk investments in the legacy
services, while only deploying the upgraded broadband they can sell. They know
that the broadband standards are evolving rapidly, and they benefit by waiting,
and not deploying more than they need to keep up.
Not quite. My repeated position is that the FOTA broadcast aspects of TV can,
and probably should remain ATSC 1.0, as long as OTA broadcast is used in the
US. To support 2-way service, the broadcaster *COULD* reinvent themselves as
wireless broadband providers, taking on a whole new business model that has
little to do with TV broadcasting, or they could leave that up to the
incumbent cellcos. (To support Internet delivery of their/conglom content,
broadcasters could fill the role of CDNs).
Fair enough. Bottom line there's not much reason to obsolete all of those ATSC
receivers you love so much. I would only add, that it would NOT be difficult to
add h.264 capability to almost all existing TVs with ATSC receivers - many
already have chips that can support this as part of their Smart TV features.
Stations could offer a legacy MPEG-2 service using say 2-3 Mbps, and recover
the rest for h.264 service. Worst case, a cheap HDMI dongle would be needed,
and I suspect that all of the "limited-use" boxes would be happy to support
such a broadcast upgrade.
I think that the advanced ATSC 3.0 broadcast schemes may have more appeal in
other countries than the US, countries where unmetered Internet broadband is
still very hard to come by.
Clearly this is part of the reason that ATSC 3.0 is moving forward.
