Does anything? My understanding is Blu-Ray doesn't support it. How about when viewing photos on these HDMI 1.3 media players.

How about when viewing photos on these HDMI 1.3 media players.There is talk that the first thing to take advantage will probably be games - but that may be a while off. I don't know about photos, but if the device you are using to send the photo doesn't support it, then no.

It's a big chicken and egg thing. Deep Color won't be supported by media until there are enough compatible devices; Deep Color-capable devices won't show up until there is something to play on them.

One thing for sure - you will pay a premium to be the first on your block! :D

Yes... it is my understanding that everything in the chain needs to be Deep Color compliant: the media, the connection, and the display.

It sounds like video won't be happening anytime soon. However, I was curious whether digital photos would make use of it right now if you have the supported hardware.

Today, right now for consumers, there isn't much.

You can download a few of the "open source like" cg movies, such as Elephant's Dream and Big Buck Bunny as exr files (www.openexr.com - Exr is a great file format used mainly in vfx post production and in 3d rendering).
The exr files can carry p3 (and really any) color gamut desired. I don't know what colorspace the people who created Elephant's Dream or Big Buck Bunny used though. However, even if they just used rec 709, there could still be some advantage to having more than 8 bits per color channel. Why both sony and usoft both dictacted a new media format with only 8bits per channel is beyond me....
I especially dark scenes having more bits makes a huge difference.


All of that said, you'll need to come up with a solution to do real time playback, and here I'm afraid it isn't really plug-n-play. You could buildup your own tool set (see djv_view for a starter.. it's very good). If you are dong this just to watch some content I'd highly suggest you save the hassle and just buy RV, FrameCycler, or pdplayer http://www.pdplayer.com/downloads.html


Windows 7 does have a few new video driver models that include display modes with more than 8 bits per color channel. They aren't commonly used by programs now, but as others have said I suspect we may see games use this soon. If people notice, then I bet you'll slowly start to see more media coming. Stuff like shorts, special one of ads, that sort of thing.

As for "real" content, in theory the DCI and digital content packages could potentially really take off, and those could in theory be sold to end consumers.
