1.2.2.2.1.3 Quantized Coefficients for Color Space Converter in HDTV
This section quantizes all the coefficients of color space conversion based on a 10-bit system for HDTV
application. These coefficients can be input to the registers of programmable color space converter. Refer
to register section for the corresponding register setting.
