    I think any upscaling TV can do better than just copying the values of neighboring pixels for the new upscaled picture. This is not a new technology. I think really good upscaling needs some costly processing. My Samsung JS9000 does really good upscaling, and it has an "octacore" processor.

    I also think there is no real end point to how good upscaling can get in the future, for the pictures that we humans tend to watch. People's faces are important to us -- we can tell the TV more about the structure of faces, so the computation can be done better. One lawn resembles another. Mountains look a lot alike. ...

    There are lots of regular properties of English words that a guesser-of-missing-characters could exploit in order to make better guesses. I take your argument to be that upscaling is a difficult problem, and that good upscaling has to incorporate into the algorithm some knowledge of what video images are like. I accept that conclusion.

    I dispute it. There is no such fact of biology.

    So you think the human eye can view resolution to infinity?

    Nothing I said above has any reasonable connection with viewing "resolution to infinity". You said a fact of biology prevents us discriminating UHD, but you don't say what this "fact of biology" is. I say that's BS -- there is no such fact.

    Is that clearer?

    I most certainly didn't say "a fact of biology prevents us discriminating UHD". Read what I wrote again, without your in-built bias towards any post that isn't drooling over 4K like it is the greatest thing in history.

    Looking back, here is what I see:
    Supposing "a given person" is a human, "a given screen size" and "a given distance" are things the given person might encounter in the given person's media room, right there it is, in black and white.

    Now, are you going to tell us what this "fact of biology" is?

    The resolution of typical human eyesight. It is like using a 10 megapixel camera and expecting 40 megapixel results. Once you have exceeded the resolution and color depth of the camera in question (in this case, the human eye) adding resolution and color depth to the image being viewed does not help.


    (BTW: I am not defining the limits of human eyesight in this post. I am noting that there are limits, and once those limits are exceeded additional visual information is useless.)

    So if you try to see something that goes beyond the limit of what you can see, then you won't be able to see it. Yep, I guess I'd have to go along with that.

    Pretty much, you stop discerning detail. Have you ever been to the eye doctor? At some point on that scale you start seeing dots, or just blotches on a white background instead of the actually letter.

    Well, I see a sharper picture on my 4k TV's satellite programming. So what if it isn't native 4k. I can get that on Netflix, Amazon Prime and Youtube.

    Any news from DTV about 4k transmission ? Or plans of that ?

    Perhaps someone have an access to hidden 4k channels ?

    If DIRECTV was talking about live UHD, I'm pretty sure you would have seen it here.

    This article suggests that live UHD isn't really on the RADAR:

    http://advanced-television.com/2015/02/20/directv-outlines-4k-plans/

    The key quote:
    Ostensibly, "not any time soon" probably means not under Mike White's leadership.

    From my perspective, they've got some distance to go toward reaching all the UHD TV owners before they get serious about linear UHD programming.

    Weird. There's already a 4K channel announced :) :

    http://4k.com/news/dutch-media-company-brava-releases-first-real-4k-broadcast-channel-6594/

    Yeah, dbstalk is a small sample size in the big picture, but its probably a larger sample size of DirecTV fan boys and videophiles and I don't see too many people yelling from the roof tops about how they just watched Ghostbusters 2 in 4K for $20, so... :).

    Which is what I said in the post you took issue with. It was you who extrapolated that to you watching your TV in your media room.

    Been meaning to ask you this: What kind of TV did you have before you got the 4K set? Just curious, I've been reading your posts with interest.

    Yeah, its a POC channel. You weren't expecting CBS to air TBBT in 4K next week, were you? :) Still, it disproves the naysayers who still say "4K linear channels will never happen". The article that Harsh posted pretty much has Mr. White saying that he doesn't have the foggiest clue which direction things will go in, so DirecTV is prepped to go both ways. I do agree that VOD will happen first. But the truth is, 4K hardware isn't out yet. Only 4K TVs are available. And only the 2015 models are really full fledged 4K TVs. AVRs, UltraHD BluRay, STBs, etc. aren't out for another 6 months or so.

    With all that being said, I still think the 2016 Olympics will be available in 4K in some form in some country :).

    Those aren't true "native 4K" sources. I'd call them more like "4K resolution".

    I haven't heard anyone saying 4K linear channels will never happen. The dispute is over how quickly they'll come, and how many there will ultimately be.
