What video is sourced at the 4K level today? Broadcast, cable, DVD, Blu
Ray? Anything?

I think it's easy to argue that, aside from the greater flexibility in
modulation choices, everything else described here can be offered with fully
backward-compatible upgrades to ATSC 1.0.
This piece is purely promotional...
"Look at all the opportunities!"
But it is based on a false premise:
In the modern digital era of smartphones, Wi-Fi, tablets and the Internet of
Things, broadcast television based on ATSC 1.0 just can't keep up. It can't
address consumers' powerful desire for higher-resolution images, improved image
quality, a better sound experience, and enhanced personalization and
interactivity, as well as better accessibility and more robust emergency alert
capabilities. Nor can it deliver the accurate audience measurement that media
companies demand, or allow them to take advantage of the latest innovations in
video compression.
This is just pure PR crap.
Most of the new competition, especially video streaming to mobile devices, is
not better quality/higher resolution/better audio. It is accessibility and
convenience. 480P is becoming the new standard for video delivered via the
wireless data carriers.
Whatever market there is for 4k video is mostly premium at this time, not
something broadcasters need to offer. As we have discussed recently, 2K (or
less) with HDR and WCG is more than adequate to deliver the kind of quality
viewing experience the masses are looking for.
And all of this can be added to ATSC 1.0.
This comment is telling:Thank you Bert!
"Not one of the aforementioned functions or content delivery models is pinned to the
ATSC 3.0 standard. The standard was carefully defined as a platform capable of enabling
such functions and models, but it is up to broadcasters to decide how best to leverage
this powerful platform to improve the television viewing experience, extend their reach,
and address their own technical and business requirements."
Which is the whole point. I think that after all is said and done, the one-way
broadcast physical layer improvement is the only true advantage of ATSC 3.0,
and all of the other advanced features, always mentioned, are layered above the
physical layer, and can be added just as easily to ATSC 1.0.
There is a strange similarity in this comment, and one we made to the FCC way back in
1992. "Just standardize the modulation layer and let the marketplace decide about
the stuff above the physical layer."
It's called extensibility. It is what everyone BUT broadcasters are doing as
technology evolves. It's time for broadcasters to update their service;
actually long overdue.
The big breakthrough will be the realization, and action by broadcasters, to
move into the 21st century and understand that they don't need a new standard,
they need to embrace the standards that their competitors are using.
That being said, I have no problem with broadcasters moving to an improved
physical layer, as long as they leave the rest open to innovation...
Just like the Internet.
