That's funny. Craig, what "you told" the FCC back then was basically wrong. You
didn't understand the difference between "the service" and "the layered
protocol." We've been over this many times. "The service" can and *must*
establish standards, to *ensure* interoperability. The problem was, your camp
was still uninformed. It was early days of the Internet, though, only 10 years
into its existence, and you confused the "extendible" and layered IP suite,
with the apps that run over it.

And anyone who understood the difference between the service and the digital
link KNEW, even back then, that A/53 could easily be updated. That's the point!
We've been over this countless times too, way back. You thought that A/53 was a
"point solution," which you repeat that in this post, and I kept telling you
that it wasn't. The standard can be changed at the stroke of a pen. THE ONLY
PROBLEM IS LEGACY. Apple *wants* to obsolete its iToys as soon as possible.
Instead, the ATSC does not have the luxury of obsoleting everyone's TVs every
couple of years. Not everything in the world has to emulate iToys, Craig.

Hardly. The "real world experience" is that TV over the Internet is habitually
problematic still (what? Can't get cbs.com and fox.com on your iToys yet?),
while ATSC TV is totally reliable. If you have at least -85 or -80 dBm of
signal strength, and at least 15 dB of CNR, you get reception.

Rubbish. There were many office suites, and MS Office won out. We ourselves
used multiple suites, e.g. Smartware, Framemaker, Lotus, but the corporation
had to standardize for interoperability. Practically the entire industry, and
government, chose WordPerfect at first, and then migrated to MS Office.
*That's* why it had to happen. If you're going to collaborate, within the
corporation and between the company and the clients, you naturally want to use
the digital tools available out there, but the tools have to be compatible.

Another funny from Craig. Yes, I admit that upgrading is a nuisance, but hey!
Aren't you the same Craig that was extolling the virtues of innovation up
above, telling us that the ATSC TV app is "stagnant?" Obviously, Office is
updated to offer new features, to keep competition at bay. And yes, competitors
are still there, and they might even take MS Office's place. That changes
nothing. Enterprises will still want compatible apps. That's the only important
point.

Again, you're getting lost in your rhetoric. In principle, **OF COURSE**
one-way broadcast distribution pipes are not mandatory for TV distribution.
That's already true today. But the TV app still needs to work reliably, no
matter what the distribution medium. The real-world experience is, over ATSC it
does. Over the Internet, well, a little bit amateur night still.
And it's almost certainly true that "the TV app" will need a two-way medium of
distribution, for any significant new features it might want to introduce. So
yes, the one-way broadcast pipe is likely to be phased out in due course.
That's why I am not waiting with baited breath for ATSC 3.0. SO WHAT? That
changes nothing about the need for standards.
