Remember, Craig, that the verbiage used to describe ATSC 3.0 is still quite
vague and even seemingly illogical. There is no reason to believe, at least
not that I've seen, that the 6 MHz channels must only be applied to one-way
broadcast. Some of the words we have seen, to describe ATSC 3.0, only make
sense if the spectrum becomes a cellular scheme. Now how many unicasts could
it support then?
Not many. Obviously it would depend on the density of cell sites, but 6 MHz is
not much to work with, especially is you are also delivering a live HD stream.
Let's focus again, Craig. What you call "live stream" is ALREADY not live. It
is simply streamed from one source location, as a mosaic of recorded segments
and some actual live studio content.
OK, how about linear streaming channel?
You are trying to convince me, and the broadcast community that the era of
programming a "channel" is over. This despite the fact that you rave about all
of the linear streaming channels you can access via DC and Baltimore multicasts.
I agree that consumer behavior is changing, especially as it relates to the
consumption of episodic television programs. And the broadcast ratings tell us
that their audience share is declining - FWIW, this decline is far more
precipitous than the decline in MVPD subscribers.
Now federate that, as I described, so you can assemble this supposedly "live"
stream at multiple distributed servers. Now tell me why you need any one-way
broadcast pipe. I repeat: historically, that was the only way to distribute
wide-spectrum content to the masses. It's not the only way anymore.
Because the industry is still making billions operating the one-way broadcast
pipes Bert.
I would add, that many of the hundreds of cable networks most subscribers don't
watch are fed from multiple distribution servers. Server technology is not
limited to the Internet. Cable and DBS systems use servers to insert local ads.
The fact remains that some "linear broadcasts" still attract audiences in the
tens of millions, and advertisers still pay big bucks to reach these audiences.
Ever browsed the web, Craig? Did you need a "screen full of icons"? I can
access the entire world of Internet content, with hardly any icons on the
desktop screen. Why is it any more difficult to use browser shortcuts, or a
search engine, than it is to punch some 3-digit number on the old remote?
Each new technology brings with it a new way to navigate. There are many
ways, far far far better than your "channel numbers," to access huge amounts
of content.
Agreed. Almost everyone agrees that the UI for TV is horrible. And many people
are not interested in using a web browser as the front end to their TVs.
I would also add that when I click on an icon on my Apple TV I see a front end
that has far more in common with a web browser than a TV remote control. The
push for HTML5 extends well beyond a web browser interface - it is a toolbox
for GUI design, just as was the case with Flash, which it is replacing.
Actually, what you said was "why not broadcast." You don't need to stop all
"live" distribution, but there is no longer a need to BROADCAST that live
material. That's all.
That is your opinion. I doubt that Mark Aitken would agree.
Funny question. What do you do with all these stables, if no one has any
horses anymore? Gotta keep horses standing around, I guess, otherwise no more
stables. You need to progress beyond these legacy notions.
You are hopeless...
;-(
Ever heard of cellular 2-way networks?
Yup. And they keep buying up more spectrum and building new cell sites to stay
competitive. 6 MHz is a rounding error for the Telco's.

Craig
