ok i'll wait

HDMI 1.3 displays seem right around the corner now that the PS3 has it incorporated and the new HD dvd player comign out next month will have it. hopefully Sony will release a new SXRD with 1.3 in febuary.

thats a great article thansk alot for posting that, that was exactly what i was looking for , for information about deep color and the new color standard.

reading that it seems like deep color and the xvYCC color space are two separet things. So does this mean that deep color woudl be able to hit the billions of color mark and get rid of banding without needing the new color standard?

The banding has already been covered but I can't deny that Deep Color and higher bit processing within the display can play a role in reducing the potential for that problem even more. The big key is...

A source that is meeting video standards will output 8 bit correctly making that function unnecessary.

... so don't make any more of it than what it is.

Absolutely!

Deep Color is the bit stream and communications specification for higher bit levels so we can expand the color gamut.

What will feed that capability?

xvYCC color space or the ability capture a far wider color gamut then we currently do!

You can't take full advantage of the system without having both in place and only services or products not related to mass broadcast and the DTV standard will be able to take advantage of it. DTV is locked in stone based on what was possible in 1996.

I predict PC graphics and gaming to be the first in line taking advantage of this new system.

i read a posting from some else on anotherr site talking about the new color standard saying its kinda pointless cause most of the tv's out now (except for some good CRTs) cant even display all of the RGB color from todays color standards . is this true?

Sure, there are some displays that don't have the right primary colors and can't be changed; remember, the manufacturer sets up the display to induce your purchase, not for accuracy. Many are capable but most require an ISF calibation to make it happen so I would disagree with that.

No displays are fully capable of the Deep Color capabilities yet but have certainly expanded what was. As stated, at this time it is nothing more than adding more sugar... it is an artifact... an ISF calibrator is going to shrink that gamut back to current SMPTE-C or HDTV primary colors if the display will allow it.

Based on everything we have discussed you need to decide if you seriously want to take this plunge and work with your local calibrator to make sure you get a display that will do current standards. It isn't nearly as easy as going to the store and picking one out on your own but the long term payoff is so much larger if performance is your goal.

This is a very cool link... may require Internet Explorer to get the java application working right. At the bottom are pictures of what happens when color decoding is not being performed properly.

If stuff like this matters to you then you want to work with an ISF calibrator to select the right display!
