Will we see 1440p or 1600p Blu-Ray?

[Jacobisthe]

Will we see any 1440p or 1600p blu-rays. All current blu-ray will support up to 4 layers (100gb) with the possibilitie of 8 layers (200gb) in the future. Also, hdmi 1.3 willl support 1440p (it might do more I am not sure), and with display-port comming out on computers supporting something like 2160p, will we see any disks with support for 1440p or 1600p on the third and fourth layers, and leaving the 1080p on the first and second layers for backward support? It seems like a good idea with newer computer monitors that are 1440 and 1600, and projectors and high end hdtvs that will support those resoltions soon, it would be cool.

I won't be surprised if it does happen cause technology always gets better. Thats why I don't buy movies anymore, just the hardware.

The Blu-ray spec doesn't go beyond 1080p or offer anything higher than 48Mbps bandwidth.

1440p would really be a new format, and it isn't something you're likely to see unless 1440p displays become widespread.

And, it could be argued that it would be better to first go to 4:4:4 and deep colour before extending the luminance resolution any further, and could be taken advantage of sets even today.

Well, they have changed the specs once already. I think they should do deep color, and 1440p in a new profile, but keep the disks backwards compatible.

Remember, the current hardware would have to be able to handle it. So, it can't be 1440p (or deep colour) encoding.

It might be done with a layered codec approach (the secondary video channel containing missing information). But, you're stealing bandwidth from the primary to service that. So, in effect, you'd be downgrading Blu-ray for everyone but those with 1440p capability.

"1440p" or "1600p" are not working video formats for movies at all. No one is creating anything in those levels.

"1600p" is the only one of the two that could have any slim chance of being used since the 2560 X 1600 pixel level is currently supported by high end 30" widescreen computer monitors. Those operate via dual-DVI connections rather than HDMI (although HDMI possibly could be made to work with that).

The only area where 1440p figures in is with old, obsolete 1.33:1 computers monitors with 1800 X 1440 resolutions. Outside of that, 1440p is a very dead thing. It doesn't matter at all if 1440 is a 2X multiple of 720 (the main thing some are holding strong to for arguing the need for 1440p video). If any successor to 1080p is going to be marketed for movie playback formats and monitor display it will have to be a significantly higher jump in resolution than merely 1440p. The 4K thing is really the only standard that has any chance within the next decade.

In going from DVD to Blu-ray we've seen a 600% jump in pixel count. A 2560 X 1440 level is just not enough of a jump above 1080p to get lots of people to upgrade to an entirely new generation of video playback hardware.

Something along the lines of 3840 X 2160 or 4096 X 2304 would be more enticing and more supported by 4K digital intermediates by the time that generation beyond Blu-ray was ready for introduction to the consumer marketplace.

So, instead of needlessly talking about incremental "1440p" and "1600p" standards, it would be better to forecast the introduction a decade from now of 2160p or 2304p video.

1440p I can see but any higher I dont think its worth it.

[Turnda643]

I really don't even see the point of this topic. Blu-ray hasn't even become the main video format and some of you are already talking about 'upgrading.' Let this format evolve and make its way into every home. and then in a decade or so. We'll talk about the next 'best' thing.

[TenEightyP]

I think it is bound to happen. Any way that the studios can repeat sell titles to the public is always going to be attractive to them.

Still think they will hold off until Blu-ray have reached near saturation levels as it makes sense to squeeze every last penny from a format.

HDMI Category 2 cables are already rated with enough bandwidth to support 1600P video plus HD audio.


The players will need an upgrade to support the codec (simple firmware update via bdlive?)

The discs will need new codecs and larger capacities (both possible), and the players better be made backward compatable.

The problem is that there is no content (other than kung fu panda or wall-e maybe) that would be ready for the media for some time. Movies aren't made in 1600p or even 1440p. There's only a couple small exclusions to that rule however.

So it won't be for a LOOOOOOOOOOOOOOOOOOOOONG time.

Just be happy with Blu for now, i am.

They're going to change the Blu-ray specs anyway for 3D. I don't see why they can't add new resolutions to the specs as well for players with the new specifications. 1600p or even 4K could be Blu-ray's new years resolution

I doubt they need new codecs for higher res. The codecs themselves can handle higher resolutions than Blu-ray is currently capable of. They'd probably need need new codecs for the new version of 3d.

The PS3 could probably be updated to support higher res as I think it uses software playback, whereas the standalone players use dedicated chips don't they where those chips are designed to work at a specific resolution - eg. 1920x1080. So the current standalone players couldn't easily be updated for higher res - they'd probably need entirely new chipsets - there are chips that work at higher res but they aren't in any existing player - so it would be new versions of the players that they'd have to release.

No, the next logical step IMO would be to make the studio's 4k (4096x2160) masters available for home viewing. This is for you guys with the 8' + screens. For his mere mortals 1080p is plenty.

And I really don't think a firmware update would be possible to update existing players to support a resolution greater than 1080p.

You can be reasonably sure the studios will want to offer their upcoming 3D fair on such a new 3D spec.

Where are the >1080p movies coming?

I thought Sony for one had installed a 4K pipeline - and doing all their finishing of new projects at 4K? Wasn't Hancock also finished at 4K? Even some older films have been scanned at this res I think. CGI can be rendered at whatever res they want as long as they have the time. As well as film, they can use the Red cameras.

If you are saying the studios won't want consumers to have such resolution - they probably said the same thing about giving consumers 1920x1080 res content, and before that they probably said similar things about DVD and VHS. Some people already say Blu-ray gives a better quality picture than some cinemas - except that it doesn't have the colour depth - that would be another thing they could add to the spec. It would also still be 4:2:0 unless they changed it - which is something else which makes it different from cinema/digital cinema I think.

I've also read that they want to use 3D as one way to seperate cinema from HDTV to give a better/different experience for cinema watchers. But if the studios are prepared to put their 3D content on Blu-ray using a system similar to what's available at the cinema (ie. a better 3D system than is currently available on Blu-ray), then they may not mind so much putting higher res content on either. Also, if players could be updated to do higher res, once any one title is put onto Blu-ray at that res, even by someone just using a Red camera, it could make other studios do the same, as otherwise they could be seen as giving out a something not as good as what the other person had released resolution-wise.

You miss my point. Where is the drive for offering >1080p on disc going to come from?

If its robbing the 1080p space and bandwidth on the BD disc, that certainly won't be appreciated.

The higher res displays that will be shown at CES this year and people wanting content to display on them at their best quality and resolution.

I don't know what the best way to put them on the disc would be. They could put it as a seperate disc and charge a certain % extra for this version. Or as someone else suggested, they could make a 4 layer disc if possible and use some of layers 3 and 4 for the 4K version or layers 3 & 4 could contain the extra info somehow to increase the resolution. But an extra disc or discs would probably be easiest and charge extra for them.

Plus, if the specs were added to for 3D and higher res, the bandwidth max of BD could also be increased for this BD profile and if you used a seperate disc for the higher res version you wouldn't make any negative impact on the space or bandwidth of the standard BD version.
