From what I understand the PS4 can output 4K movies but not games. I may be wrong, but I remember reading something along those lines somewhere.
How would that not work for games? It can but the graphics wouldn't be as good as people would expect.

4K/8K will be just like 3D niche as fuck
Don't expect to see enough content worth purchasing hardware.

I tried to google but every source has something different.
The main question is:
If I buy a PS4 today, will I be able to play 4k (3d would be interesting too) blurays?
I need to convince my partner (who is not a gamer but a serious movie-nerd <3 ) that this console is needed in our apartment. So the more future proof ps4 is in this department the more chances are there for me to finally pull the trigger
But can the PS4 decode HEVC at 4k in software?
Because the underlying mechanics are the same, there's already what's needed inside the drive to physically move the lens up and down to change focus.A. "Matter of focusing the laser on another layer" is most likely a physical design issue which cannot be remedied with a s/w firmware update. I doubt that PS4 BD drive blue laser has any means of focusing anywhere but on two layers of 25/50 BDs. Because why would it?
As I've said, it's all about using a more efficient error correction algorithm.B. 66/100 4K BDs are not only about layers but are about density on each layer as well as each layer now holds 33 GBs of data instead of 25 on the old BD. This leads to different laser positioning mechanics which is a physical problem again that cannot be fixed with software.
You bet? ^_^I'm 100% certain that you will need a new BD drive to be able to read 4K BDs.
The SDK doesn't allow it for games, simple as that?How would that not work for games?
It's not like GPUs have been used for years as accelerators to decode videos, huh?That is an interesting question. The current hevc software decoder from vlc requires 4xi7 cores running at 2.3ghz. So with cpus alone this would be very tough and would require that the decoding can be appropriately multithreaded. Offloading to gpu could work, though.
Stop. 4k is literally 4x the pixel count of 1080p, it is insanely demanding. We will never see 4K games on PS4. Feel free to save this post, and if it ever happens (it won't), I will eat a shoe and post pictures for GAF.
Manufacturers are producing much less 1080p televisions. There probably won't be any in a year or two. 4k won't be niche.

From what I understand, the PS4 HEVC decoder for 1080p content is still a bit dodgy. 4k is going to require a lot of effort and as DieH@rd points out HDCP 2.2 support is not there.
Is there a decoder already? This is new to me. Also hevc doesn't require hdcp 2.2.
Reading UHD-BD requires it.Also hevc doesn't require hdcp 2.2.
Not enough processing power to run good looking 4K games?

Actually there's a lot of 4K content being produced. It's not being released though, because there's no platform right now, and not much of a market.They could stop making 1080p tv's today it doesn't change the fact No one is producing 4K content.

That is what they said about 1080p. This is only a natural progression of the medium. Either get with it or be left behind by technology. I've got my 4k Bravia ready to go and have watched a lot of 4k content already on my streaming. By the end of this year 4k blurays will be available. It's coming. I've also watched the entire Breaking Bad and DareDevil series on 4k streamed by netflix.
They're not the same as having two focusing positions is obviously different from having three of them.Because the underlying mechanics are the same, there's already what's needed inside the drive to physically move the lens up and down to change focus.
I don't know the details on the new UHD BDs yet - and I don't think that anyone does at the moment - but it's unlikely that a change in the error correction algorithm would bring a +50% capacity to the same physical base. That would mean that current BDs contain more than 50% of duplicate data for error correction which seems to be awfully inefficient and unlikely.As I've said, it's all about using a more efficient error correction algorithm.
Same thing used for reading BDXL, that Sony invented by the way, like somebody else said.
Never understood how that works in online, sorry.You bet? ^_^
I'm not forgetting anything but the matter of fact is that the hardware needed to read and playback UHD BDs is simply absent from today models of PS4. Even if it is possible to make it work through a shitload of hacks and standard breaches I don't think that Sony will bother - it is better for them and us to just get an updated h/w which will handle the task natively and in compliance with specs.Don't forget that Sony is a founding member of the Blu-Ray Disc Association and of the HDMI Forum.
They knew what was coming years before the specs were published, and they also told us they had designed the PS4 with the future in mind, so they may well have done what is necessary to upgrade the console through software.
Which codec do they use, which resolution and what is the bitrate?
I asked some guy at best buy (dunno how reliable he'd be), and he said all it'll take for Ps4 going 4K is a software update.
I should've said employee**** at best buy.About as reliable as any random jackass you might bump shoulders with on the street.
4K/8K will be just like 3D niche as fuck

How many posts did it take. Here's your answer and it wont support streaming from say Netflix either without thisThe current PS4 does not support HDCP 2.2 protection so no, it will not support UHD Blu-Ray playback.
I'm pretty sure the team behind Trine 2 said they managed to get the game running in 4k at 30fps on a PS4 dev kit.
(The game also runs in native 1080p/120fps for its 3D mode)
Whether it ever sees the light of day is dependant on Sony unlocking 4K games output of course.
If film is shot in 4K+ then I'm sure film companies will sell 4k versions of the film, If I'm buying a bluray (as I often do) its a no brainer to pick up the 4k version instead of the SD version IF the cost differential is small.
As 4k tv adaption increases it will become the norm to have the 1080p and 4k versions bundled, just as they do with DVD and bluray now.
It already does!!!111!

Wouldn't Sony corp prefer people buy new players?

Think the best answer is "maybe" or "ask again later" no one really knows for sure. I would be happy with updated Netflix 4k and other streaming 4k content
It's really the same, because optical drives are already permanently adjusting focus to compensate the disc's surface irregularities.They're not the same as having two focusing positions is obviously different from having three of them.
Read this: BDXL brings the expanded layer capacity by increasing the linear track density (which by itself doesn't need any hardware change) and using an algorithm called i-MLSE.I don't know the details on the new UHD BDs yet - and I don't think that anyone does at the moment - but it's unlikely that a change in the error correction algorithm would bring a +50% capacity to the same physical base. That would mean that current BDs contain more than 50% of duplicate data for error correction which seems to be awfully inefficient and unlikely.
DBXL is a different beast altogether.
if 3D is possible through an update why isn't 4K?In order to play 4k Blu-ray, it would need entirely new player hardware. Unfortunately this will not be possible on PS4.
However, prior to PS4's launch, Sony mentioned that even though games would not be output in 4k, video can. What they were referring to is 4k streaming/downloads, which is 100% possible.
So 4k video yes, just not 4k Blu-ray specifically.

No. Current PS4 BD drive doesn't support the new BD capacities of 66 and 100 GBs which will be used for 4K BD standard. And I don't think that any BD player on the market support them at the moment.

Ultra HD Blu-ray's a new format requiring new dedicated players, it's backward compatible with Blu-ray and DVD.I thought Blu-rays didn't have the storage or bandwidth for 4k? Or is this a new format and they're just sticking with the Blu-ray name?
SPECIFICATION NOTES
4K / up to 60p
High speed display in 60 frames per second of 4K video (3,840 x 2,160 pixels - Ultra HD), which has four times the resolution of Full HD/Hi-vision, for highly detailed videos with extremely smooth movement.
10-bit gradation
Previous Blu-ray Discs displayed the color signals (Y, Cb, Cr) in 8-bit gradation each (256 gradations). By expanding this to 10-bit gradation each (1,024 gradations), even minute signals can be faithfully reproduced to realize richly textured video.
High Dynamic Range
A technology that drastically expands the brightness peak from the previous 100 nit to 1,000-10,000 nit, marking a significant leap in the dynamic range of the picture. Bright light sources (e.g. lights or rays of the sun) and reflected light (from metal or water) that up to now were difficult to display can now be shown in rich textures.
BT.2020 wide color gamut
Compliant with the ITU-R BT.2020 wide color gamut signal formulated for 4K/8K broadcasting. Enables vividly rich coloration not previously possible on Blu-ray discs (BT.709 standard).
HEVC (H.265) / 100Mbps
Support for the highest 100Mbps video signal using the latest high-efficiency video compression technology. Compression efficiency and high bit rate far beyond previous Blu-ray discs (MPEG-4/AVC (H.264), maximum 40Mbps) enabling outstanding playback of high quality video with 4K/60p/10bit, High Dynamic Range, BT.2020, etc.

Doubt it. Prices already dropping to reasonable levels on 4k sets. It's just a higher resolution, not some gimmick that requires you to wear goofy glasses.

AAA games that sell consoles, obviously.What's a good looking game?
Yeah, there are actually. And I want developers to have the choice to make simpler, stylish games at 2160p.So many good looking 1080p games that weren't running like shit on the PS3, right?
