And we want more colour too.
Are there any virtues in having uncompressed "2K" 1080P content along with a fuller colour spectrum, vs whatever means they choose to encode 4K ?

Uncompressed video is *much* too large to make sense. Uncompressed 1080p video with simple 8bit per channel RGB would already consume exactly 1TB for a 2 hour movie (hope my math is correct). If you use a larger colorspace, you probably want to use more than 8bit, then the movie file size increases accordingly. That just doesn't make any sense today. Ok, you could use lossless compression (similar to TrueHD for audio), that would help quite a bit, but it would still be too large to make sense. Video compression is still necessary today, but bitrate could be increased, or better codecs used. RED claims to have a codec which works much better than h264. Basically RED is saying that they can use Blu-Ray like video bitrates (file sizes), but they can compress 4K into that with a bigger color gamut, higher bitdepth, no color subsampling and less compression artifacts. Whether what they claim is really true is still up in the air. We'll have to wait and see on that...

I think the key problems with Blu-Ray today are studios/encoding houses screwing up, by using stone age 2K masters and/or by using DNR/edge enhancement and/or by using lower bitrates than necessary and/or by not applying proper dithering.

madshi, maybe the better solution right now is put pressure on the authoring houses to get their 'sh!t tog...' I mean get their ducks in a row.

New formats won't necessarily cure all problems. If we don't let them now about the problems... they will carry the same ones over along with possibly creating new ones specific to a new format.

The studeo will like that. We can now buy another copy of a Bluray because it A, was down resed from 4K, and B, it is at a longer bit rate. And then we can buy it again when it comes out in 4HD. brilliant.

That's exactly what I said and meant by saying having preordered the Redray hardware, I'm wondering if was that wise given Sony are moving into the hardware(download) based system alongside Red. If Sony had of jumped to a new 4K disc format, I'd say ok, that was kinda expected. But instead they've gone with essentially the same concept.

+1 Agree 100% Mark. Most def all the hallmarks of whats happened previously with all the high bit rate DVD of the past, then Bluray remastering,etc...I know I've bought my share the same movies in diff formats like that, starting with Laserdisc remasters!

There is essentially no information on the announced 4K content distribution system other than it will be server based. OK. Sony now has servers built into its commercial projectors. Distribution is by hard memory copy. The Sony head honcho knows such a system wouldnld work for the 4K display consumer and wants it to be download based. That's about it for now. Comming this summer (unless delayed to work out kinks like cidex and protection and how much it will cost for a piece of content and whether the purchase is in perpetuity or for a limited viewing window. Yada yada.

Are they trying to establish their own Odemax. We know absolutely nothing and we can infer that 4K bluray is several years off.

And/ what are they showing? Come look at our pretty server. It looks like a server. The only issue is content. We know the specs, they are quite acceptable. What we don't know about is content. What content was toshiba showing outputted from the Redray server?

It was just some 4k footage, which looked fantastic. I will see if I have time to go back.

Thanks. Prettyeasy to shoot something on a Redray 4K camera and load it on the server. And then use Odemax to send it to other servers on the Odemax network.

For some information about the Redray player, a little about the Red "Crimson" laser light engine projector and info about the Red 4K camera watch this video interview from CES 2013:
