Colorspaces
DVI is limited to the RGB color space. HDMI supports RGB, but also supports YCbCr 4:4:4 and YCbCr 4:2:2.

^ - As this is digital, it's not actually YUV but YCbCr - See http://en.wikipedia.org/wiki/YUV#Confusion_with_Y.27CbCr
xvYCC-encoded video retains the same color primaries and white point as BT.709, and uses either a BT.601 or BT.709 RGB-to-YCC conversion matrix and encoding. This allows it to travel through existing digital YCC data paths, and any colors within the normal gamut will be compatible.
