As we have discussed, h.264 is not available in most cabled systems.

That's false. When cable system broadband transfers streaming media, it uses
H.264. So clearly, any numbers you do to estimate the capacity of repurposed
cable bandwidth, repurposed for Internet streaming, only needs to consider
H.264 (and eventually H.265).

The case was simple: both OTA broadcast and cable are locked into
legacy technology.

You got lost in this thread, Craig. We are talking about gains to broadband
deployment which can be achieved if cable systems convert their broadcast
spectrum to 2-way Internet use. You old mantra does not apply. (Plus,
parenthetically, there's no reason in principle why codec upgrades can't be
transmitted over ATSC 1.0. There's already a standard that covers that. It's
not used, but that's not because the standard can't handle it. You've been
confused for years on this point.

Yup. Just tell your subscribers to suck it up and live with reduced
quality...

Not at all. Instead, you ask subscribers of the broadband service how much
quality they want to pay for. A home with 5 Mb/s service can get very decent
H.264 HD, in fact.

It is not the FCC that matters here. It is the ability to deliver
a comparable or superior service that will determine when we move
from bundles of linear streams to bundles of live and on demand
content delivered over the Internet.

Again, Craig, you get lost in your rhetoric.

A single person living alone can get excellent Internet streaming image
quality, with 5 or 6 Mb/s of broadband. And so on, with increased capacity
required depending on how many simultaneous HD streams that household expects
to use. The 5.7 Gb/s of capacity now broadcast into every home is wasted for
the most part. Internet streaming works on a different principle.

This just proves that the cable part of the infrastructure in place today *can*
be used for Internet streaming. It is, if anything, the mirrored server aspects
that have to be improved. OBVIOUSLY the cable companies can improve both. Just
don't try to make us believe that we're decades away from this being possible.
