Deep color may also be referred to as xvYCC, or Extended gamut YCC.
It is extremely important to understand that every movie that was ever transferred to a DVD or other digital format has been transferred using 8-bit color depth. While the newest Deep Color format might give an improvement in the quality of the picture, there is no content currently available, no archived material, no movies, and no TV shows, that can be trans-coded easily into the new system. With the current problems of Digital Rights Management (DRM) and High-bandwidth Digital Content Protection (HDCP) just starting to be worked out, it is highly unlikely that the entertainment industry and Hollywood will hurry to produce software that is an exact copy of the original movie quality. The first place Deep Color will be used is in advanced gaming systems, starting with the Playstation 3 in November 2006.
What deep colors actually means is that
there are more colors.
With a color bit depth of 30 bit the number of available colors becomes one billion. If the color bit depth is changed to 36 bit, the number of available colors jumps significantly to sixty nine billion colors. If the color bit depth is changed, this time to 48 bit, the available colors will number 2800 times one trillion. This is an enormous amount of colors. Plus a higher bit resolution can display more shades of gray. With 30 bit color depth four times more gray can be represented. Eight times more gray, or even higher, can be represented by a 36 or 48 color bit depth.
Researchers have estimated that the amount of colors seen by the human eyes number in the tens of thousands. But, depending on the lighting conditions and any surrounding colors, a human eye can tell the difference between millions of differing shades, an example is that you’ll be able to distinguish many more shades of black in darkness than you can see in brightness, so the additional shades will show a noticeable difference, but it is uncertain when the number stretching stops becoming useful to the human eye.
