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.

4K sets need more space

Jason Perlow Unless you've been living under a rock -- or have been blissfully unaware of the goings on at this last CES, you'd know that the products at the front and center of every major consumer electronics manufacturer (save Apple) have been the latest and greatest 4K, ultra-high definition TV sets. And right now, they are crazy expensive, starting at around $25,000 each.

I'm not here to argue that people won't own 4K UHD sets, or that we won't see 4K being used in computer displays or even tablets in the near future. In fact, I'm absolutely certain that the prices of these things are going to come down and become commodities and low margin products -- just like the current generation of 1080p HD displays are today.

In three years or less, I won't even be surprised to see 4K screens on a full-size iPad, a 10" Android device, or even a Windows RT tablet.

My issue is not the price of the screens themselves, it's how the content that will be delivered to the displays will be achieved. And right now, if you examine the state of consumer broadband in the United States, most households are barely able to stream 720p movies reliably, let alone 1080p, which is Blu-Ray quality.

To move 4K movies across the Internet, we're going to need to move bureaucratic mountains at the state and municipal government level to get gigabit connectivity to the last mile in every major metropolitan area, unless we are prepared to distribute content on 128GB high-speed flash drives at Wal-Mart or figure out how to free up broadcast spectrum that doesn't exist.

  • Is it a big enough difference?

    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

    Everyone laughed at hi-DPI displays, too, until they saw one. Now it is a must-have feature on phones and tablets.

    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 . . .

      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

        But are the "stair steps" you are seeing a result of the display resolution or the games picture resolution? From what I have seen, many "John Q Publics" can't tell the difference between NTSC and 720p of 1080i(which is all ATSC braodcast allows!). Indeed many can. One of the biggest visible differences between old analog and newer digital TV, is the lack of "snow". That... people notice, resolution.. not so much. My opinion comes from 35 years experience as an inhome Television technician.

        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.

          "But are the 'stair steps' you are seeing a result of the display resolution or the games picture resolution?"

          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 issue of content will persist for many years. HD content is only now becoming truly common place and even it comes at a price premium. HDTV got started in the early 90's. That is 1990's and it is now 2013. 20 years. 20 years to go from SD to HDTV once the tech was available.

      The move to 4K will be even slower.

    • Much bigger than 50

      50" is a good sweet spot for 1080p, but just like a 30" HDTV, the higher resolution is lost on a smaller screen and 720 is fine for those. Thus it will be for 4K...I'm thinking massive, wall-size screens. On typical screen sizes that we see today, the difference in quality vs. price will only appeal to hard core enthusiasts. But the possibility of good quality, massive displays will bring something to the table that 1080 can't touch.

      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

    It is bizarre while there is supposedly are demand for higher and higher TV resolution much of the news broad casts consist of very low res picture shot on mobile phones or SKYPE hook ups where little attention is paid to lighting or microphone placing.
    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

    Do I see a use for 4k TVs? Yes, I think it would be awesome and I look forward to it. But that isn't the question. The question is delivering 4k content to the TVs. BluRay can scale to support it, one of the reasons it was a better choice than HD DVD. But outside of that? You can't stream it. 1080p stresses most connections. I'm not sure how existing providers would be able to deliver that bandwidth without major overhaul of the infrastructure. By the time that happens I think we'll be past even 4k TVs. Perhaps the 8K TVs that Sharp showed off would be more likely. When we have gigabit to the house.

  • 4K is about movie distribution - or not

    I feel both are off the mark. A new video technology is about the distribution of content. We do remember that Hollywood held up release of Bluray for more than 2 years while encryption was improved, right? Despite the fact the media and burners could benefit ordinary DVD quality in terms of less compression, size of the media, or use for backup. No mfg produced Bluray burners until Hollywood agreed to movie distribution.
    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.
