Opening Statements
The future of TV is 4K
Steven Vaughan-Nichols I have seen the future of TV and it's 4K. Don't get me wrong I love my 1080p HDTV, but 4K's 3,840×2,160 pixels, aka Quad Full High Definition (QFHD), blows it out of the water.It's not just the four times better definition. I see 4K TV becoming a blockbuster because it will be bundled with organic light-emitting diode (OLED) technologies with their exceptional color reproduction.
Yes, there are two major problems. First, it takes a heck of a lot of bandwidth to move 4K video. Lossy video codec technologies, such as the just approved High-Efficiency Video Coding (HEVC) is going to bring that down to 100Mbps broadband speeds.
The other problem is that OLED 4K TVs are more expensive than some cars. Those prices will go down eventually.
So why is 4K's going to win anyway? Because, I'm taking the long view. By 2015/6 Gigabit Internet connections will be more common. Simultaneously, I see 4K TV prices will drop into the 2-grand range.
4K will still only be for hardcore TV fans, but it will be a mass market. It happened with HDTV, it will happen with 4K as well.
Talkback
Is it a big enough difference?
I'm sure that I'll likely notice a difference - but I'm not so sure that most people will care.
Especially the tech press who claims that the difference between 720p and 1080p is indistinguishable (although I personally beg to differ - I can tell the difference). I can see similar claims popping up with 4k.
There's also the issue of we have nothing that supports it. We'll likely need a new optical media format to fit an entire movie (increasingly unlikely as more people just use the internet for video), and it would require even larger internet bandwidth. Nevermind that it's currently really hard to get an internet connection that can handle 1080p.
And of course it will likely require we do something to how changing channels works on both broadcast and cable. And I don't think there are very many channels that go the whole 1080p even now.
It's the chicken and egg problem all over again. Except this time I don't think people are really gonna be convinced to move to the new format.
I'm sure I'd personally love it. But selling to to the public and the tech press may be hard.
Similar to Retina
Beyond crunching the numbers on pixels and 20/20 (or less) visual accuity, there is something inherently satisfying about a display that looks great close up even after you step away from it. At around 50 inches or bigger, which isn't rare these days, even the John Q Publics will want one.
A note about that 20/20 thing . . .
. . . it's not a maximum.
20/20 is basically "you don't need glasses or contacts." It's not the maximum possible vision for humans. Some people have vision as good as 20/10, and possibly as good as 20/8. I'd imagine that before age starts deteriorating their vision, most people likely had better than 20/20 vision at some point in their lives. There are of course exceptions. Most doctors will simply stop the test at 20/20, and most people won't bother to ask their doctors to test their vision beyond 20/20.
On my iPhone 4: In 3D games (and yes, at a comfortable distance, at about 10 inches which the phone is designed at), I can see the stairstepping effect from a lack of antialiasing - that means even on a so-called "retina" display, it's still possible for some people to still see the pixels.
Stair steps
There is also a bit of the, "I just spent $2500(well, $800 today) on this new tv, of course it looks better!", going on as well!
In the next 2 years? Pipe Dream! in the next 20? I don't have a crystal ball!
on an iPhone, they are the same.
On an iPhone, they are the same, unless it's a really old game that never updated to add retina support. iPhone games generally don't render at a different picture resolution than the display resolution.
The "stair step" effect is caused by a lack of antialiasing, and I very much know it when I see it, as somebody who has played games for years. I can certainly tell the difference between upsampling and aliasing. Photographs and live action videos are naturally antialiased, but game images aren't, due to the way that rendering technology works for 3D games.
The Wikipedia article on "Aliasing" shows the stairstepping effect I am talking about.
While the screens are simply gorgeous, content will be a serious issue.
The move to 4K will be even slower.
Much bigger than 50
I don't think 2014/15 is going to be the coming out year though. 10 years maybe? We'll see. Bandwidth must get much bigger and much cheaper for this to gain traction.
4k TV
much of the information content of TV broadcasts is carried by the sound channel but lapel mikes are commonly used which lead to very muffled speech also there is an increasing tendency to deliberately blur pictures to prevent people being recognised.
The only things that would benefit from higher resolution are adverts where no expense is spared to get the best sound and picture quality.
Talkbacks need to keep in mind the subject of the debate
4K is about movie distribution - or not
This will play out again: no serious use or driver to the larger displays without media content, and the question becomes: when/how will Hollywood agree to near-theater-quality material being distributed? I feel the encryption and protection will take many years to sort out. In any case it is not about the technology or Internet bandwidth, it is about the content protection.
