Am wanting a digital cinema projector, capable of playing DCI spec content from a media block, that is also capable to display non-DCI 4K content via outboard devices connected via DVI interface. The Sony R320 does not have that capability. To do both, I'd need two projectors, e.g. an R320 and R420. Does anyone know if, once Christie ships 4K CP2230, or Barco ships 4K DP-2000, if those boxes will support 4K via DVI interface in addition to the media files-based method for DCI spec content? Thanks!

Yes to series 2 Barco Christie.

The 4k will be able to thorough the PCIE connector to the media block, hd sdi or through the hdmi 1.4 port of the IMB.

if the new 4k dlps have a true hdmi 1.4a input they should do it
at least in 2d with 3840x2160 may also 4096x2160 at 24p.

so press your fingers that the picture Peter post from the doremi media block will have full 1.4a hdmi standart.

for me the problem will be bigger as i like to feed my own
3D stills at 4096x2160 in 3d at 48p from a computer
and i not see anything that can do it today.

but as beside me others like the vr people will need this as well
i hope for a solution that will be easy.

If you buy an IMB board now , it will not be 1.4. In July.

Same with the dimension 3-D box.

i hear this displayport can do also 4k in 2d.

do you have more informations about it?

max resolution max hz......
i not have it.

you know my problem to feed 4k resolution in 3D and that means
3840x2160 or 4096x2160 at 48P!!!

Wolfgang, I only knew it would support much higher datarates than even the latest 5.6 gig of HDMI, but don't know the standard itself. 1.2 was standardised and issued late December, so I expect the website to have some discussionpapers on newly added/updated 3D support (according to wikipedia this is new in 1.2). http://www.displayport.org/cms/?q=co...s-white-papers
http://en.wikipedia.org/wiki/DisplayPort

Seems Displayport isn't to forthcoming with whitepapers at least not on its website.

This doesn't spell good news, Wolfgang: http://www.reghardware.co.uk/2010/01...es_dp_1_dot_2/

"For a single display, this enables up to 3840 x 2400 resolution at 60Hz, or a 120Hz 3D display at 2560 x 1600."

But 21.6Gb/s, 5.4Gb/s per lane, should be plenty of bandwidth for two 4K signals, shouldn't it. The 4K monitors to date are perfectly happy with 4 HDSDI inputs...

if displayport can do 4k at 60 hz its fine as the input to the
4k pr. needs to be 4k at 48p only(2x24 p left and right interleave)

the tripleflash 2x 72 hz will be anyway create inside the pr.

peter i only like to say that may the first true 4k dlps
will be ship still end of this year if everything runns well

And in a years time Intel will start the roll out of Light Peak.

“Sony is excited about the potential for Light Peak technology that Intel has been developing, and believe it could enable a new generation of high-speed device connectivity.”
- Ryosuke Akahane, Vice President of VAIO Business Group, Sony

“Nokia believes that Light Peak technology enables new wired connectivity solutions for Mobile Computers and Smartphones, and looks forward to working with Intel and the industry to create a global standard based on Light Peak technology.”
- Markku Verkama, Director, Devices R&D Technology, Nokia



Light Peak module with four fibers each capable of carrying 10Gb of data per second. (Light Peak module with laser light added for illustration; actual infrared light is invisible to the eye)

Quote:


Light Peak Overview

Light Peak is the code-name for a new high-speed optical cable technology designed to connect your electronic devices to each other. Light Peak delivers high bandwidth starting at 10Gb/s with the potential ability to scale to 100Gb/s over the next decade. At 10Gb/s, you could transfer a full-length Blu-Ray movie in less than 30 seconds. Optical technology also allows for smaller connectors and longer, thinner, and more flexible cables than currently possible. Light Peak also has the ability to run multiple protocols simultaneously over a single cable, enabling the technology to connect devices such as peripherals, displays, disk drives, docking stations, and more.

Existing electrical cable technology in mainstream computing devices is approaching practical limits for speed and length, due to electro-magnetic interference (EMI) and other issues. However, optical technology, used extensively in data centers and telecom communications, does not have these limitations since it transmits data using light instead of electricity. Light Peak brings this optical technology to mainstream computing and consumer electronic devices in a cost-effective manner.

Some images postet on Reduser of the RED RAY pro 4K player/server as shown Reduser event Wednesday 14 april in Vegas.
This machine was reported demoed doing 4K playback from CF or SSD at 15mbs to the latest model Sony 4K projector.

What compression scheme are they using. 15mbs seams very low especially for 4k material.

RED has not released any proper specs. for this player yet. The original idea was to use DVD as media at 10mbs. But because the lack of 4K displays I guess they estimated that when 4K displays starts to be available in the future the Compact Flash and SSD media would be affordable as delivery media.

This is the Pro player, and it would probably be more correct to call the media stream "as low as 15mbs 4K". The machine can probably play back at much higher bit rate. Without knowing for sure, just reporting "rumours" and reading between the lines, this machine might have the same ASIC processor that is in the new small Epic Camera that can process 5K Cmos signal up to something like 100fps. and store it.
Logic is that it should be possible to decode and playback the same.

Basis for all RED codecs (Cameras, Processing and Editing software) is their own REDCODE, which some say is a variation of Jpeg2000, but is not something they have published.
So a variation of REDCODE is probably the codec for RED RAY.

There will also be a Consumer version of this player, which originally was said to cost $1000, but no other or new pricing for these machines has been given.

The reports on the image quality was like "fantastic" and "impressive on a Huge screen". But the pictures I have seen from the event was that the screen was not particularly large and I believe it was a backprojection, and I would not trust enthusiastic "camera gearheads" to report accurately on this.

There are rumours of an upcoming REDUSER event on the east coast and maybe some critical HT people from AVS could attend and check out the quality.

4K @ mere 10~15Mbps with "fantastic" quality, ONLY if they put Merlin (the wizard) inside that thing!
