4k Resolution - What It Is and What It Means for TV and Home Theater

4K-2.jpg
As far as providing 4K over broadcast, satellite, cable, or even streamed via the internet - the required extra bandwidth that would be required could necessitate big infrastructure costs, and with the cost incurred by broadcasters and other providers for the recent required DTV transition, there is no enthusiasm to do it all over again for 4K.
On the other hand, development is in progress on new video compression techniques that might actually be able to squeeze all that additional data into the current HDTV transmission and streaming infrastructure.The Korean Broadcasting Service actually demonstrated possible 4K broadcast transmission technique, and Netflix demonstrated a possible streaming solution for 4K, at the 2013 CES. However, before these, or other solutions can be widely implemented, agreement for a specific standard would have to be settled, including provisions for some form of backwards compatibility with current technology.
For the uninformed, 4K refers to video displays with a resolution pushing 10 million pixels. That’s more than four times as many as you’ll find on current 1080p HDTVs. While 4K projectors have been demonstrated at previous trade shows, they were mostly professional models. But JVC and Sony showed consumer projectors at CEDIA 2011 that will begin shipping before year’s end at the real-world prices of $8,000 for the least expensive JVC model and $25,000 for the Sony. Why the big price difference? Sony’s VPL-VW1000ES is a native 4K (4,096 x 2,160-pixel) projector, while JVC’s models use a proprietary technology called e-Shift that displays 3,840 x 2,160-resolution images from a native 1,920 x 1,080-rez chip.
If you’re contemplating the move to 4K — either native or the e-Shift variety — what will it mean for your current setup?

Whenever a new technology comes out, there’s the question of whether existing cabling infrastructure will work. When DVD came along, component replaced S-video. And with HDTV, HDMI eventually replaced component.
Here’s what we know about 4K and HDMI: True 4K source material (not yet available to consumers), as well as video signals upscaled to 4K resolution by a video processor, will place significant data demands on the cable, requiring data rates of about 8.91 Gbps, or double that of 1080p/60.
To get the straight dope on whether 4K will mean another new cable, I reached out to two cable manufacturers, Audioquest and Kordz. The short answer: probably not. Audioquest’s Shane Buettner explained, “4K will undoubtedly increase the data demands of the HDMI cable significantly, and in all likelihood require a High Speed-rated HDMI cable that can transmit HDMI’s maximum data rate of 10.2 Gbps.” And Kordz’s David Meyer added a warning: “Since HDMI launched new labeling guidelines in 2009, the message has been that you need a Standard HDMI cable for 720p/1080i, and a High Speed cable for 1080p. Some segments of the market have taken this to mean that High Speed equals 1080p. [High Speed HDMI cables should support up to 4K-rez video, which is included in the HDMI 1.4 specification.] As such, we’ve observed many HDMI cables being promoted and labeled in the marketplace as High Speed, but actually only operating to 1080p/60 — around 4.45 Gbps or so.
“Bottom line,” concluded Meyer, “for 4K support, use an HDMI cable which is genuine High Speed and certified to operate to 3.4 Gbps/channel, being 10.2 Gbps total. Since many cables are mislabeled for marketing purposes, how can you tell? Stick with reputation, and stay away from cheap unknowns.”
What does the future hold for 4K 3D? Said Buettner, “There’s no current HDMI spec for 3D at 4K. HDMI 1.4 supports 4,096 x 2,160 at 24 frames and 3,840 x 2,160 at 24/30 frames. But it doesn’t support 48/60 frames. This seems to preclude a 4K 3D signal being transmitted over HDMI 1.4 from the source to the display.”
Will Your Blu-ray Player Still Work?

Since there’s no true 4K content available right now, 4K projectors take regular Blu-ray and HDTV signals and upconvert them. This scaling is performed in the display — or in a video processor connected to the display — so your existing Blu-ray player will function with no problem.
But according to Sony, if — or, more likely, when — true 4K content arrives on Blu-ray Disc, the situation will be just like when Blu-ray 3D came out. That means your player will definitely require more than just a simple firmware update; you’ll need to upgrade to a new model.
Next month, I’ll discuss how 4K will affect your selection of a projection screen and where you sit when watching movies.

HDMI :: Manufacturer :: HDMI 1.4 :: 4K Support

"The term actually covers two formats, both supported in the HDMI 1.4 specification:
  • 3840 pixels wide by 2160 pixels high
  • 4096 pixels wide by 2160 pixels high"

I hate that shit. They should just standardize it. Same as how there's some monitors that are 1920x1200 and there's some 1920x1080.

Just make it 4096 by 2160 and call it good. BTW the first one is 1920x1080 quadrupled, the second one I'm guessing they rounded it up to 2^12 for compression and rounding purposes...

As far as the "not exciting" part, no shit... I mean, they can always lower the bitrate (not sure if that's possible on TV) but that'll just look like shit. I think 4K is doable with internet speeds though. It'll take at least 30kbps for decent quality however, so it's right on the edge of "streaming" for the fastest connections today. It might be nice to have it offline though.

I'm guessing it'll take a while for it to pick up, but it should be pretty damn awesome for home theater/gaming enthusiasts (along with movies on *insert new post-blu-ray format here*<insert new="" format="" here="">).</insert>
 
Sorry for adding to this heat. I like the post. I hung a lot of RJ6 & 12. Along with a lot of fiber for comcast in the Chicago land area. It made me think of what is on the poles and can it do 4k. Looks like we have something to look forward to. I just hope it doesn't come at a big cost to us.

They had 4K upconverting Bluray Projectors out around 2008 for the rich folk. Last couple of years have seen Ultra Low Resolutions of 4K on 100 to 150 inch TV's I say that in a day in age where 1600P just made it to 10 inch form factor and 2160P (4K) is just now hitting "large" TV's :p yeah i know the weight of a large screen supporting high PPI would be crushing.

If they would wait for H.265 supporting hardware the bandwidth requirements would only be half of what they are expecting and only double that of 1080P OnDemand content or Bluray.
