4k & 4k Blu-Ray....aka 4 layer discs talk thread
Though technically inaccurate, the term '4K' is being used loud and wide at this year's CES in regards to the next generation of TV sets that boast a 'Ultra HD' (UHD) resolution of 2160p, making it four times as detailed as the current 1080p standard.
As 3D has failed to take off in the home TV market, manufacturers are falling back on what they should be focusing on - improving sets via a combination of both higher resolution, and better quality images that boast stronger contrast ratios and wider color ranges.
The move to 4K is an issue at the moment because, frankly, there's little to no content available at that resolution. There's also the debate about perceptual differences - beyond better colors, a TV screen needs to be at least 60 inches before one sees a noticeable difference from an average living room viewing distance.
Netflix is testing the standard this year, broadcasting high-profile titles like its second season of "House of Cards" at the standard, and other VOD services are expected to follow suit in 2014. Even so, bandwidth issues relating to speed, overall cap limits, and compression artifacts mean streaming the amount of data required for a 4K broadcast remains an issue - especially in areas outside of major U.S. metropolitan areas. Even with the much more efficient video codecs in place, the data rate is still too much for a big chunk of potential viewers out there for at least a few years anyway.
That leaves discs. The catch with Blu-ray? Current dual-layered Blu-rays are 50Gb - not enough for a 4K film. This week though, Samsung Australia Philip Newton revealed to The Australian that Samsung had the technology in place to produce high-capacity four-layer Blu-ray discs with 100Gb capacity which should be large enough.
Newton expects these discs to become available "by the end of the year," and Samsung would make 4K players available. In fact, the optical technology has already been available "for years".
What's the hold up? At present it's manufacturers settling on a compression standard - either HEVC (H.265) which Netflix is about to employ, or Google's rival VP9 which is currently in use on select clips on YouTube. The industry doesn't want another format war, so four-layer discs will appear "once everyone is on the same page... except for the standard, it's good to go."

Gonna be interesting about the quality of streaming 2160p.
Compression artifacts galore?

I said the exact same stuff that's bolded in a thread like 8-12 months ago. Lol
And look into 265. Pretty cool stuff.

At least the industry got smart and kicked the 3D nonsense to the curb and are now focusing on the stuff that really matters like contrast, resolution, picture quality.
Once the content can be delivered, people will by the new 2160 screens in droves....assuming of course they are not rocking 48" televisions.

I will never buy a 2160P TV. Simply put, at my viewing distance of about 12-14 ft, the biggest TV I can have is 42" because of the size of the wall indentation I have. It's one of those closet inlet things typical of 5-10 year old Florida homes. Maybe one day I'll say screw it and get a 60" and just mount it on the wall, but that's still a couple of years away, at least.

I'd jump to 2160p if the content was there. The picture quality is fantastic.
That being said, I wonder if the new PS4 can read 4-layer discs?
Gonna be some pretty pissed off PS4 owners if it doesn't.

Most movies have been scanned and archived in 8k for years now.
Distribution is the issue.

I know my Baraka bluray says 8k on the cover...but those of us who anxiously waiting the movie all knew it was made from an 8k scan.
RED...does make a 4k "hub" for media called the redraw for about 1g...its probably the most worthwhile thing RED ever made.

I've never seen a movie on bluray try to sell itself as 4k...interesting.

'Mastered in 4K' is just a marketing trick to make consumers believe it's the super new UHD.
As Sarlacc pointed out most are mastered from one and encoded to 1080P.
