JVC has also joined the 4K projection party

These prices are getting interesting ... still way off my perception of the mark where regular people will buy.

If these are the prices the "big guys" are coming up with, I'm increasingly excited to see Red's offering!

4K e-Shift?

Curious to see this side by side with the other entrants.

What little we know about the JVC at this point sounds like fuzzy math meets marketing fluff, but once it's on the street we can see for ourselves.

The other DILA projectors produced very filmic images, so I'm hopeful this turns out better than it sounds... definitely seems like a questionable approach versus native chip/panel resolution.

The JVC does not support 4k input. http://www.hometheater.com/content/jvc-goes-4k

As a side note, the Sony 4k uses a single HDMI 1.4 cable, which means 4096x2160 @ 24p and 3840x2160 @ 30p. No 48 or 60p possible using a single HDMI cable. http://www.hometheater.com/content/sony-vpl-vw1000es-demo

How do we get there, from here?

How do we get there, from here?

I have been banging this drum for 3 years:

We need a viable interconnect standard for 4K.

When I demoed 4K "dailies" (actually shown 3 minutes after I pulled the drive off the camera!) at CineGear in 2010 I had to run SDI over 8 BNC cables from the RedRocket Breakout Box to the Sony L560 monitor (thanks again Band Pro and Miguel from JMR). I'm sorry but 8 lanes of SDI is not the answer.

While 4 lanes of HDMI should support 48fps 4K S3D it still doesn't strike me as a great idea.

What will the I/O be on the REDray player?

With 4K display products hitting the streets, like the Sony VW1000ES, that use limited bandwidth interconnects like single HDMI 1.4 taps, what kind of investment are they? I understand that I will have to pay the early adopters price for such products but the idea that it will either be obsoleted or require a serious hardware retrofit in the not too distant future is cooling my ardor.

I fervently hope that one of the reasons RED has not yet released the REDray is that they want a robust interconnect with display devices hitting the market. I suppose RED could just put a whole bunch of ports on the REDray (adding to the expense and complexity of the back panel) to support current and evolving interconnection options...

Anyone with specific technical knowledge PLEASE chime in, the following is my best understanding and reflects my belief that any standard that cannot support 48fps 4K (4096 please, not 3840) S3D is not worth developing/implementing as its shelf life would be too limited. Let's take a quick look at some of the candidates:

HDMI - unless there is a lot more unused potential in the HDMI spec than I know about we are talking about a 4 cable solution. There are also cable length issues. Hard to imagine that catching on.

SDI - still looking at 4 cables even on the 3G (sometimes referred to as dual link) versions. I have heard of 6G SDI but have never seen it, this could make a 2 cable solution possible.

Display Port - AFAIK a 2 cable solution is possible in theory...

Thunderbolt - I am hoping this might be the single cable answer, from what I have read a fiber version of TB could carry two channels offering 20Gb/sec throughput...

DisplayPort is used by many CE companies today as an internal interface. However, they are still using HDMI as the external interface. I know of multiple 4k devices that are planning to use a single HDMI interface. This prohibits 3D 4k with one cable. The same InfoFrame field that is used to signal 4k is the same one that is used to signal 3D. You can signal one or the other over HDMI today.

We may see a 4k update to the Blu-ray spec down the road, but will probably not be until HE AVC is finished, which is the successor to AVC. (H.264)

I agree -- the dynamic range of the mid-2000s JVC pro D-ILA projectors were really good, the best blacks I saw with mid-sized (16' and under) screens. And they were really, really reliable, too. But not cheap.

The 4K Sony SRX-420P is very costly, but does 4K very well. The Sony requires a proprietary dual-channel SRLV connection plus an accessory LMT-300 Media Block, so it's not a simple "plug it in and go" set up. But it puts out a great picture.

While this isn't a true 4K image (the imaging chips are still 1920 x 1080 and the projector will not accept a 4K input source

Whats the point if there is no 4K input......????:furious3:
