xvYCC/Deep Color? - Blu-ray Forum

Go Blue · 08-30-2007, 03:52 PM

I have a HLT5089S Sammy LED DLP, Onkyo TXSR605, and PS3. All support HDMI 1.3. I have HDMI cables connecting the components. In my Sammy's picture settings, there is an option to turn xvYCC/deep color on. When I do this the picture looks very dull and the color looks muted. Does anyone know why?

well, to start, there are not too many sources aside from camcorders that even use xvYCC/Deep Color...so its useless at the moment.

also, I imagine you would have to re-calibrate (brightness,contrast,color,tint...)the HDTV to adjust for this setting.

and, there is a setting in the Onkyo that either "enables" or "disables" this setting, do you have it on?

Yes, I turned it on in the Onkyo. When will I be able to see the benefit of this feature? Since all my components support it, do I just need BD's to support it?

yeah, BD's have to support it.

Home Theater:xvYCC and Deep Color

"But There's a Catch
In order to make for a wider color gamut and a higher bit depth for even more realistic-looking displays (capable of creating a wider range of colors), every step in the chain needs to do that exact thing, as well. If the camera can only do Rec.709, it won't matter that your TV can do more than that, because that extra color isn't in the source (which is, uh, the situation we have now). If the camera can do xvYCC but the medium (say, HDTV broadcasts) can't, again, it won't matter that your TV can do it. In other words, for you to see the new colors, material will have to be shot, transferred, encoded, and mastered in xvYCC and Deep Color. Sure, you could fake the wider color gamut at the mastering stage, but this won't be true extra color."

hope that helped.

Once you go Deep Color, you have to ensure that every step of the playback chain supports Deep Color.

Also, you will have to re-calibrate your display as your display probably has different profiles for normal and deep color.

Another thing to note is that just because its has more color fidelity and a calibrated display provides you with accurate color reproduction, doesn't mean it will look good to you, just means it looks the way it is supposed to look as it was shot/composed.

So, all BD's have xvYCC color?

If thats the case, and all my components accept and pass it, I have to say it does not look like anything I would call "deep color". I thought this would be a much more noticable feature even without callibration. I'm a little dissapointed.

Has anyone else seen xvYCC color in action?

In order for you to take advantage of deep color with Blu-ray movies, the movies themselves have to be encoded with the higher bit rate color. Either way, human eye can't distinguish any difference beyond 30 bit color, so I don't know how useful this feature will be.

yes in my store we have the sony xbr5 and the sony w3000 next to eachother and when you turn it on and off is a noticable difference. the w3000 with x.v.color on is a little better than the xbr when x.v.color is off...but when you turn the x.v.color on the xbr looks amazing

Are you watching a BD when you are comparing? If so, which one?
