You don't "end a thread" by compounding your errors, Craig.
I repeat: broadcasters do not design the TV sets.
Broadcasters DID NOT design the ATSC 1.0 standard
Broadcasters participated, but this is irrelevant. The fact remains, you are
obsessing over nonsense. Broadcasters cannot change the standard at the drop of
a hat, simply because they know that the receivers out there will go dark. So
you're just wasting words, and time, by insisting on this idea that
broadcasters should change the standard. It takes a big effort, a la ATSC 3.0.
Everything broadcasters need to move to h.264 compression, while
retaining ATSC 1.0 modulation and transport, is already included
in most new TVs.
That's too preposterous even for Craig (maybe not). You still have to define
the new container, Craig. Get real. Just because a TV set *might* also have an
IP front end, and an awful lot out there **do not**, it doesn't mean that the
H.264 decoder can be reached from an ATSC over MPEG-2 TS stream, just like
that. Besides, you obsess over old codecs. We have to get to H.265 or
equivalent, for 4K.
It is now trivially easy to build external boxes
It always was! So what's your point? You would still alienate a lot of TV
users. And as soon as a new standard exists, manufacturers build what's needed
into new sets. You're just repeating your old mantra from a couple of decades
ago, and it was just as simplistic back then.
What have CDNs got to do with this Bert.
Everything. They make the IP streams available in multiple formats, for the
different devices that use them. Unicast allows a receiver to negotiate with
the edge server, Craig. One-way broadcast does not. The only way to satisfy
multiple incompatible devices with broadcast is to simulcast.
Meaning that moving the ATSC 3.0 requires a lot of new infrastructure.
Not sure why you felt obliged to write all those words. Was this ever in
dispute?
You don't need a new TV to watch Netflix.
You need a new front end, though, unless you own a connected TV that allows
Netflix streaming. Again, are you just writing words for not good reason?
Wrong on all accounts. The camera DOES acquire HDR images using the
multiple exposure/image processing technique. And the new displays DO
deliver enhanced dynamic range under appropriate viewing conditions.
Aaargh! Insistent cluelessness. The camera's three exposures are going to
limited range displays. That's why they have to fill the display with a
combination of the three images, Craig. Read the explanations, confound it.
The dark parts of the scene, when sent to the display, are filled with the
**overexposed** camera content. So the dark parts of the scene don't look black
on the display.
The bright parts of the scene, when sent to the display, are filled with the
**underexposed** camera content. This is so the bright parts don't look washed
out, on the display.
**This is called "compressing the dynamic range."** The dynamic range of a
scene is reduced, to display a more pleasing, even if distorted, image. Read
the literature. Do not insist on things you don't get.
Bert FINALLY gets it.
I always "got it," Craig, but unfortunately you still don't. You are stuck on
this dogmatic view of the world, even when it makes no sense.
If a 4K display sells for no more than an HD display, then people will start
buying 4K. It's that trivially simple. Same happened with HD. It became cheaper
than much of the old analog fuzzy stuff, so obviously there was no point
getting stuck on dogma.
Same with your "high res audio." My first response to you was that eventually
it doesn't help much, so why bother. But you didn't understand that. The point
remains that if high res audio sold for the same price as CDs, then of course
everyone would start buying it, EVEN IF the difference was inaudible. When the
opportunity for a new audio player comes up, you just buy whatever is best and
still affordable. Sam with 4K sets, Craig. People don't care about your dogma,
get it? They buy a 4K set that is easily affordable, they see a smoother image
even if way up close, and they're happy. All depends on cost and perhaps size.
And neither are problems anymore.
