7.3. YCrCb to RGB Color Conversion (HDTV).
Color information recorded in the color palette provided by each PGC is encoded as luminance and color difference coded signals (YCrCb). This encoding is popular among many component video systems and is used by the DVD-Video standard.

The reason for using YCrCb signal is that the human eye is less sensitive to chrominance than luminance. Compression algorithms can take advantage of this phenomenon and subsample the values of Cb and Cr without significant visual degradation of the original color signal.

On computers, color information is recorded as red-green-blue signal (RGB). Use the following equation to approximate the converted values of YCrCb color information into the RGB components. The coefficients in the equation are recommended by the ITU-R BT.709-5 standard for HDTV.

The equations to compute the R, G, and B components from Y, Cr, Cb are demonstrated below. The complete equations and coefficients and other DVD related information are available from the Unofficial DVD Specifications 2.2 PDF ebook.
Enter values for Y, Cr, Cb in decimal (from 0 to 255) Y or choose from the following colors: Cr Cb	R = 238 G = 222 B = 2
