4K vs UHD

@thecreativeone91 Maybe broadcast is more locked down in the US, but with Digital Broadcasting, a network can stream at the resolution and aspect ratio that it wants. The TV receiving it will downsample or stretch the image, but that's up to the hardware on the user end. And HD does not refer to Interlaced Scan video, only Progressive Scan. Interlaced is used for TV broadcasting, and the occasional piece of professional equipment, most everything else is progressive scan.
This use of the 'p' was my understanding.
Yes, the need for i and p was because HD did not originally imply either. If you HD in the English way, there is nothing interlaced that is truly HD. But if you use it the marketing way, you must specify as low definition interlacing is common.

Granted Hulu does this I think.
Yeah, they suck.
Exactly - why would anyone want Hulu? I suppose if you could ditch cable and just do Hulu.. that might be OK.

Because they have exclusive show rights.

Has anyone seen or heard of 4K interlaced yet?
Hopefully no one will use it. high end cameras shooting which are the only ones doing true 4k, wouldn't offer interlaced as you'd be insane to use it. I would not be surprised to see UHD 2160i at some point even though Interlacing sucks, especially now days. was really meant for CRT days.

If you refer to something as 1080p or 720p yes then it would be progressive. But it doesn't have to be progressive. There is 1080i and 1080p. He also contradicted himself saying her that HD is only progressive and then later stating that it's understood full hd is 1080i.
Letting go of the last part - I've heard, though never really cared - that HD is either 720p or 1080i or 1080p, but HD could never be used to describe 720i. Don't ask me where I heard that, but I have heard it for years.
I'll have to double check, but I'm pretty sure my local cable company is transmitting at 720p (at least that is what my TV is telling me when I turn it on). I should call and ask if the box can be bumped to 1080p - and if it would make any real difference is the cable company is limiting itself to 720p anyway.

@Dashrender There's your answer. Film is done to look good, TV is done to comply to stringent FCC rules.
The FCC only adopts the rules created by the broadcast associations. It would be impossible to do the level of a Film OTA. You get shipped multiple harddrives that create a raid to plug directly into the the digital projector both because of size and needed data rates to get high quality. Film is DPX files, one file per frame (it's actually just a large picture file with no compression). Audio is done separately, and synced with timecode.
LOL I heard that - it's basically a giant flip book.. LOL
Though I heard they are streaming or at least downloading that data now, is that not true?
nope, all hard drives the only thing online about it is unlocking them, they have to be de-encrpyted per show to make sure theaters don't to unlicensed showings, but using them at slots they didn't pay for. That used to be a common thing in the 35mm/S35mm film days, which wasn't that long ago.
I know our local theaters had employee showings usually a day or two beforehand.. those days are gone.

It's actually worse than cable is some respects, because I can't fastforward through commercials.

Well hd would be resolution only. so it could be 720i, 720p, 1080i or 1080p. But the reality is 720i is almost never used. 720i is not a broadcast standard either.

Well that's probably where these sales guys get it from... it's not broadcast.. so the chances of seeing it are low... so we'll just not include it.

They were calling 480p "HD" back when we were doing home theatre installs with it before the last generation of HD terminology rolled around. 480p was part of the same spec group as 720i, 720p, 1080i and 1080p once upon a time.

They call it EDTV today.

For me, this type of technology, it is all about the specs given. If I'm going to buy a 4k TV, I'm going to want to know the resolution. It doesn't matter to me if you call it 4k, UHD, FHD, or SupercalifragilisticHD.... (God, please, don't make me type that again...)... If the resultion is only 320 x 240 on my shiney new 65" TV... I think I may have a problem with picture quality.
However, on a TV with higher resolutions, there comes a point where the human eye won't be able to tell a difference between the various resolutions... 4096 x 2160 and 3840 x 2160 could be a good example... Can the human eye even detect a single pixel at that level on a 55 inch screen?
-
@dafyre No no no, there comes a point where resolution is high enough and you can make a bigger TV/Monitor or sit closer

They've already proven I believe it's around 60" or bigger screens need to tell any difference between a 1920x1080 screen and a 3840x2160 screen. But, having source 4k over 1080p content does make a difference the image will be sharper and have more contrast.
Supposedly Contrast is the biggest deal in image quality is contrast, our eyes see bigger contrast as higher quality, alot more so than resolution (at least at a distance).

The problem then becomes how do I afford said bigger TV / Monitor? 8-)
-
@dafyre I shop for factory 2nd's or refurbs. Got my 39" 4k for $400 right when the GTX970 came out - sure, it turns off after 4 hours and you can't change that setting but it gives you a whole 60 seconds to abort it lol
-
@MattSpeller That sounds cool... except for the part where the abort screen pops up while I am trying to tank or heal in WoW... (emphasis on trying).
-
@dafyre I swear to god it monitors what you're doing and knows the worst possible moments.

I currently have a 45" Sharp Acquos that i purchased in 2005. I sit around 15 feet from my TV. From the papers I've seen I can get something around 75-80 and I should be still comfortable at my seating distance without it seeming to big.
I've been looking at the HD (lol) 1080p TVs. A Sharp is around $1900, but the "4K" model is around double... and in the store it really doesn't seem like that much better (if any) than the 1080p model.
