What is 4K Resolution

4K is a variety of new resolutions coming out that pretty much center around a 4000 pixel side. There are a couple variants of the 4K resolution.
  • 4K Ultra HD - 3840 pixels × 2160 lines (8.3 megapixels, aspect ratio 16:9) - for UHDTV
  • 4K Film - 4096 × 2160 (8.8 megapixels, aspect ratio ~17:9)
  • Streaming Video - YouTube 4096 × 3072 (12.6 megapixels, aspect ratio 4:3), Vimeo 4096 × 3072 to be uploaded. Netflix will stream 4K sometime in 2014 reportedly, no specifications.
In comparison to current 1080 resolutions or roughly 2.1 megapixels, 4K will be roughly 8.3 megapixels, about four times as much.

If you do a small bit of looking, you will find that the human eye goes way beyond 8.3 megapixels, so asking whether or not the human eye can perceive the difference between 1080 and 4K has already been established.
Why Do We Need it?
Because the television manufacturers say so, might be the thought on the minds of many. It's true that TV manufacturers seem to latch on to something new every year and then cram it down the throats of consumers, see 3DTV.
Do we need it? Sure, the content will look all that much better, for the consumer that has a 4K screen and a setup that will allow the 4K content to get to the screen. How many of you have a 4K screen currently? Not many I'll wager. Television prices are ridiculously high still, most people won't be buying them this year, maybe not even next year. But if you've been lucky enough to attend a CES in the past couple years, you've seen a 4K TV in action. It's extremely impressive. They seem extremely bright and the images are indeed quite a deal better than 720p and 1080p for that matter.
Now, for streaming video, which is done much of the time on small screens like smartphones and tablets, are you going to be able to see a difference? Probably not, at least, not for some time.  Can you imagine 4K on a 10-inch tablet screen? Rtings suggests that if you've got a 20" UDHTV you need to be about 1.75 feet away from it, at 10 inches one could extrapolate that down to perhaps a foot or so. Which is very close to your face in order to see any noticeable difference.
There are no 4K tablets or smartphone screens. Even Apple's Retina Display maxes out at about 2K (although a 15" MacBook Pro is close to 3K). Those screens are about 300 pixels per inch. A 10-inch 4K screen would need about 450 pixels per inch. In fact, 458ppi is what a 9.5" 4K screen has right now.

Before 4K Streaming Becomes Reality

There are a great many things that need to happen before 4K really becomes a reality or needs to do so. First off, market penetration of 4K-capable televisions needs to grow, which it most likely will as prices descend from the stratosphere into more reasonable ranges for the average consumer. Of course, if you just purchased a new big flat screen in the past year or two, are going to be ready to spend on another one? Probably not.
As for PCs, most displays aren't capable of the high resolution either, and more graphics cards can't handle that level of information or detail. Dell does make some 4K-compatible monitors, 24" and 32" with price tags in the thousands, $1,400 and $3,500 respectively. EIZO makes a 4K display as well, but it requires dual display port cabling to achieve the 4K resolution.
Graphics cards are a bit easier to come by as they have been available for over a year now. Examples include the AMD HD 7970 and the Nvidia GeForce GTX 680 and GTX Titan. The GTX 680 will set you back a good $400-500 alone. On top of that you are going to need to do some upgrading in other areas of your PC as well if it's starting to show its age.

Streaming 4K is a Bandwidth Nightmare?

On top of all the consumer-side hardware issues are issues of network bandwidth and stability. For mobile video, it's not even close to becoming a reality as the US lags behind in both peak mobile data network rates and in average speeds. So much so that, even full on HD streaming, is hit or miss presently.
Home-based broadband is far better equipped for 4K streaming. According to Netflix CEO Reed Hastings, it won't require more than a stable 15 Mbps to stream 4K. For many that means a max speed of around 50Mpbs roughly. A quick check of my broadband speed today showed a steady 22 Mbps downstream from Milwaukee to Chicago, to St. Cloud, Minnesota and to NYC, meaning I could probably manage a 4K stream today as Netflix should have a server within reach. Amazon Studios also just recently announced that it will shoot all of its 2014 shows in that format as well. 4K and 4K streaming are definitely coming in 2014 regardless of how many people can actually view it.
But can the networks handle peak usage 4K streaming? Over the past couple years the ISPs have been trying to get bills passed through Congress that would allow them to treat streaming video differently from other forms of Internet traffic, most likely because they've oversold their networks and want to start charging more for higher profit margins and network upgrades. However, if they sold X number of connections with maximum speeds at Y Mbps, then the onus to deliver is basically on them and shouldn't be determined by what kind of data is being pushed through the pipe. After all, it all boils down to zeros and ones in the end, so it's all the same type of data.
Google is showing the traditional ISPs and MSOs that it is easy to supply massive bandwidth to households at a reasonable price thanks to their 1 Gbps Fiber projects in Kansas City, Austin and Provo. Those pilot programs are also offering 8-tuner DVR and terabytes of online DVR storage. Pricing is set at $120 a month for 1 Gbps Internet connectivity and 200+ channels with one terabyte of storage, a Nexus 7 tablet and 2-year contract. That's less than I currently pay Time Warner Cable for my Internet and cable TV right now.
According to the FCC's 2013 Measuring Broadband America Report (Feb, 2013)
...the average speed tier subscribed to by consumers increased from 14.3 Megabits per second (Mbps) to 15.6 Mbps. Nearly half of consumers who subscribed to speeds of less than 1 Mbps six months ago have adopted higher speeds, and nearly a quarter of the users who subscribed to speeds between 1 Mbps and 3 Mbps have upgraded to faster speed  tiers.
In terms of satellite,
...during peak periods, 90 percent of satellite consumers received 140 percent or better of the advertised speed of 12 Mbps.
Now, at the end of 2013, with just a year to go in the FCC National Broadband Plan goal of 100 million homes with affordable access to download speeds of at least 50 Mbps (goal is "by 2015") seems to be an attainable goal and that means streaming 4K video could also reach that many households by the end of next year, provided the pricing on consumer electronics with 4K capabilities drops to a rate where most can afford it.
Looking at the April 2012 subscription tier numbers from the FCC we see that many US households may have a fast enough Internet subscription tier for streaming of 4K video (20+ Mbps), if they are, as the FCC found, maintaining 90%+ of advertised speeds at peak periods.
In this report, we find the average subscribed speed is now 15.6 Mbps, representing an average annualized speed increase of about 20 percent.
With 20% growth year-to-year, it would be around 18.76 Mbps at the end of 2014. Extrapolating further, 90% stable speed at that average would be 16.848 Mbps - enough to stream 4K, probably with some minimal buffering.
But just because households have the connection to manage 4K streaming doesn't necessarily mean we will all be able to achieve a perfect viewing experience. Network congestion could still, at those estimated speeds, cause some buffering and degrade the viewing experience, unless the video front loads faster, which makes people less happy with the experience as well.

4K Video Advertising?

I haven't even touched on what it could mean for advertising. We all know how bad standard definition advertising looks on high definition television. There are still some local stations that are showing SD ads on HD channels and it's terrible. With the shift from HD to UHD and 4K that is going to happen yet again unless the video advertisers are ready to quickly adopt higher resolution rigs. How much is a 4K camera you ask? The RED ONE, which can do 4K, will cost you more than your average new car. Sure, you could go with a Sony FDR-AX1 Digital 4K Video Camera Recorder for just $5,000 or their pro PXW-Z100 for $6,500, just make sure you have an new enough video editing software suite to subsequently edit that content, and a strong enough computer to do it on. But that shouldn't be a problem if you've got the $6K for the camera, right?

4K Future

Perhaps once the prices of 4K cameras drop below $4K we might all start thinking about it more regularly. Meanwhile, some of you might already be shooting in 4K which means your work is somewhat future proof already. As 4K video starts working its way into the streaming video industry mainstream there are going to be a whole new set of things to think about like bandwidth for sending the ads and content, storage space for it all and market penetration of 4K-capable televisions and computer displays. It will all need to be taken into account in terms of how much it costs to place those ads as well which could mean higher prices for those ad placements for the foreseeable future.

4K Ultra-HD TV Faces Bandwidth Challenge to Get Into Homes

New Video Format could be in trouble without the compression technology it needs.

Now that consumers have proven uninterested in today’s 3D TV, the consumer electronics companies have turned to 4K Ultra-HD TV as the Next Big Thing that will trigger the new upgrade cycle.
But 4K won’t get anyone excited if there’s no way to get the format into homes, or worse, if it looks no better than today’s HDTV.

4K has four times the pixels of today’s 1080p HD. The information for all those pixels can eat a lot of bandwidth. Yet the delivery infrastructure for video — satellite links, over-the-air and cable channels and Blu-ray discs — isn’t getting more bandwidth any time soon, and most consumer Internet connections can barely handle simple HD streaming.

So dreams of next-generation broadcasting and consumer electronics firms’ hopes for billions of dollars in new TV sales rest upon an arcane combination of high tech and black art: video compression.

In a nutshell, compression turns the beautiful but huge digital images coming out of video cameras into smaller, but hopefully still beautiful, digital files. Or, more precisely, it reduces the bitrate of the video stream to something the TV and Internet infrastructure can handle.

When video engineers worry over whether 4K will ever live up to its promise, it’s the bitrate they’re concerned about. The pixels will be there, but will there be enough data to make them worthwhile?

The bitrate for video can be squeezed in many ways. Color can be sampled less frequently than the rest of the picture. Pixels that don’t change, or barely change, from one frame to the next can be transmitted less frequently. Subtle information that average viewers probably won’t be able to see in a frame can be trimmed away. Or some resolution can simply be tossed out.

Peter Putnam, president of Roam Consulting and an expert on video compression, explains that the signal coming out of an HD camera has a bitrate of 1.5 gigabits per second. But the broadcast TV channels they feed are limited by law to just 19 megabits per second. Neverthess, he adds, “You’ve watched CBS, NBC, PBS high definition, and it looks pretty good.”

Peter Symes, director of standards and engineering for the Society of Motion Picture and Television Engineers says CBS pushes hard for its affiliates to use their full 19Mbps to deliver the best HD picture their bandwidth will allow. “Most broadcasters don’t do that,” he says. “They allow maybe 12 megabits for HD, and the quality is less. Maybe it’s got a resolution corresponding to about 1200 pixels instead of 1920 or whatever, but it certainly isn’t the full 1920 x 1080.”

So even today, the HD picture on some channels isn’t delivering the full potential of the format. Squeezing 4K into the same infrastructure is likely exacerbate that problem.

Today’s TVs and other devices have decompression software on a chip inside the device. But chips with 4K decompression haven’t hit the market, so the 4K TVs arriving in the marketplace are improvising their decompression solutions. Sony’s new 4K TVs and accompanying 4K media player use compression from tech company eyeIO, but the media player sidesteps the problem by downloading content instead of streaming it.

Eventually, the software and hardware for encoding and decoding commercial 4K will make it to market. The new High Efficiency Video Codec is up for official approval, and should squeeze 4K video down enough to fit into today’s infrastructure. The encoders and decoders will also improve, so 4K broadcasting and streaming should improve over time, as HD has.
