Perhaps. But we have stations that transmit one HD plus four and even five SD
subchannels. I submit to you that this is roughly equivalent. And it works.
No, Europe chose to take full advantage of the digital video
infrastructure already in place at most state broadcasters
I said that Europe missed out on HD (over DTT), and you come back with
meaningless words? How many Euro TV markets support 12, 14, or more HD channels
OTA, Craig? They can't, because of the simulcast requirement.
and HD has been available in MVPD packages for years.
Wasted words. Obviously, systems that don't use OTA spectrum won't have OTA
spectrum's restrictions. Even US MVPDs took the wasteful approach of having to
simulcast. But when you have enough spectrum, wasting it is not so bad. Plus,
you can stick your customer with higher fees for the HD, if you want to.
In other words they threw away the HD information...
In other words, they used as much as they needed. A 480p plasma set made more
use of the HD information than did those cheap 480i CRT sets. In a broadcast
medium, this is the way to go. Without making any changes to the broadcast
infrastructure, SD and ED sets faded into oblivion, and were replaced with HD
sets, and all kept using the same HD streams.
With unicast streaming, as opposed to broadcast, the equation
changes.
Yes, because - unlike broadcasters - new Internet competitors
are willing to offer these streams, and device makers like
Google and Roku are building boxes to support these streams.
Funny how Craig just can't get these concepts. No, Craig. It is much more
difficult to introduce a new service that demands a lot of bandwidth, when your
medium has to continue feeding 24/7 broadcast streams to a huge base of
incompatible installed sets. With unicast, this is not the case. As long as
your edge servers can feed the individual sets, system capacity is not much
impacted. *Server capacity* might be, except that the 4K streams can use H.265
compression, and also the 4K stream can be downconverted to HD in real time, to
feed legacy sets. Unicast, fed by servers on the network edge, makes all the
difference.
On the other hand, ATSC 3.0 could be used as the way to solve this problem.
Just like ATSC 1.0 did with HD, ATSC 3.0 will be compatible with 4K and H.265.
So no matter what set you have, there won't be a need for simulcast. Any ATSC
3.0 TV set, or HDMI stick, or STB, will be compatible with 4K and H.265, and
downconvert as required for legacy displays.
And forget H.264, will you? We have to move beyond, with 4K. How is it that you
were so anxious to have H.264 adopted, when H.262 was the norm, and now you're
stuck?
Everything can evolve if the system is designed properly
There's no problem with ATSC, as I've painfully explained to you on multiple
occasions. The problem is that TV sets are not upgradeable. Broadcasters don't
manufacture the TV sets, Craig. You didn't know? ATSC 1.0 can transmit H.265
compressed 4K video no problem. Just define a new container. What is so hard to
understand about this, Craig?
A 43" 4K set is an oxymoron.
Again, you feel compelled to grind this axe. The simple fact is, just as HD
sets became totally ubiquitous, even in small 22" sizes, heck even in
smartphones, 4K is showing every sign of doing the same thing. The new normal.
In spite of your protests.
I know exactly what HDR is, and where you can buy products that support
it.
No, you don't. You mentioned smartphones and tablets. Smartphones use a camera
that has to take three different exposures, to get a more pleasing image, and
call that "HDR." And you fell for it. So no, Craig, you evidently still haven't
a clue. And when I explain HDR, you think I'm changing the subject. Huh?
This has NOTHING to do with high resolution audio Bert. It is just the
use of better transducers to deliver commonplace digital audio.
Poppycock. So Craig, you spend the time to explain what you think high
resolution audio is, in full detail. That way I don't have to try to decipher
what it is you're missing. Because clearly, you missing something. Invest the
time to explain in detail.
