The BBC has begun a trial of 4K high dynamic range (HDR) video on its iPlayer streaming platform.
The test involves four minutes of footage from its Planet Earth II series, which promise to reveal more detail and present more vibrant colours than was possible before.
It is part of efforts to develop technologies that will make live broadcasts in the new formats possible.
But only a minority of TVs can screen the footage at this stage.
"One of the clips is a frog on a leaf with lots of rain, and the reason this is so interesting is that the redness of the frog is a really deep Ferrari red that you would never get in broadcast television at the moment," explained Phil Layton, head of broadcast and connected systems at BBC Research & Development.
[...] But programmes will cost more to make if they take advantage of the innovations. So, the improved quality will have to be weighed against the fact the majority of viewers will be unlikely to have TVs that support the new technologies for some time to come.
In the meantime, Amazon and Netflix both offer some pre-recorded shows and movies in HDR and 4K.
And BT and Sky both offer movies and sport in 4K but not HDR.
There's always the chicken/egg situation with video - without the screens that can view them, there's little point making the content, and without the content being available, there's little point in producing the screens. Has 4K reached the critical mass that will make it inevitable, or will it retreat the way that 3D did?

4K is great and all, but the reality is that it's just not that important. When we jumped from 480i to 720p and 1080p, yeah, the difference was very noticeable, but even then it wasn't THAT big of a deal. The amount of enjoyment one gets is from the quality of the programming, not the quality of the final image. Sure, watching The Avengers in high-def is great, but watching Hulk slam Loki around like a rag doll is hilarious because it's hilarious, whether it's in 480p, 1080p, or 4k.
I would never buy a TV just because it's 4K. I sure as hell wouldn't pay a premium for a 4K TV, especially if being 4k was it's only selling point. If I had to choose between a good quality 1080p TV and an average quality 4K, I'd pick the former without even thinking about it.

No ee didn't jump to 1080p, that's the problem. We jumped to 1080i, so we still had interlaced issues.
4K doesn't do interlace, it's 12gbit or bust. The extra resolution tends to be a bit by the by, but the increase in temporal resolution and in dynamic range makes a big difference.
Broadcasters are moving to 4K as the next step from hd,they're also moving to ip - although that's a far harder issue.

Well, yeah. From a technical perspective, 4K is obviously superior for a variety of reasons.
What I'm saying is that it's not superior *enough* to interest the average person and have them think, "Holy crap, I need this!". They certainly arn't going to pay extra for the privilege.

Without my glasses on I agree.

A sensible standard would bring an increase in the frequency and color range, without the unnecessary pixels associated with 4k. Apart from penis measuring, there's really no purpose in having that many pixels on screen for a TV set.
4k worth of pixels for a movie screen or a computer monitor make sense, but you'd have to sit so close to the TV in order to actually tell the difference that most people just don't have the necessary space for a screen like that. And then, there's the bandwidth and storage space necessary to make it happen.
For such a small gain, it makes no sense.

I completely agree, and I was at an SMPTE event where they presented findings which basically said that hardly anyone will benefit from 4K - based on the distance people sit from their TVs and their ideal TV size. At least in the U.K.
However when someone pointed this out, the chap in change basically agreed but said "panel manufacturers need a new gimick" to sell. 3D, curved screens, 4K without HDR, 4K with HDR, and I guess HDR with higher frame rate (there's a big difference between 60p and 120p in high speed movement). It's easier to persuade the average Joe that 4K is better than 2k, as the number is higher. Same thing we saw with cameras 10 years ago.

Or in processors at the time when Intel ranked up their CPU clock figures by simply doing less per clock.

Huh? Close? Not enough space? How much space is necessary for closeness?

Yes it was, but mostly for sports. Drama, and most movies, not so much.
Watching hockey on standard definition television is mostly a waste of time. You simply can't follow the puck. Tennis and baseball and golf are pretty much the same, and even football (any variety) can be hard to follow the ball in standard def.
I visit my neighbor, who's eyesight is not that great and he watches tennis all the time. Most of the time, I walk in, notice he is watching the standard def channel, and I switch to HD (1080p) channel for him and he is amazed all over again. I don't think he actually watches so much as listens to it.
At this time, I'm with you regarding purchasing 4K. 4K sounds like an excuse for the cable company to charge me more money, for the same crap quality drama and biased news with scrolling banners covering 1/3 of the screen.
I kind of wonder if 1080p isn't the sweet spot in this medium.
No, you are mistaken. I've always had this sig.
