Abstract
Apparatus and method for converting a Y-Pb-Pr component video signal to a R-G-B component video signal. A luminance component video (Y) signal and a red color difference component video (Pr) signal are decoded to produce a red component video (R) signal. The Y signal, a blue color difference component video (Pb) signal and the Pr signal are decoded to produce a green component video (G) signal. The Y and Pb signals are decoded to produce a blue component video (B) signal.
