Abstract
A video signal in component form is processed by generating two chroma component signals which have a selected bandwidth and are GAMMA corrected, generating a linear luminance component signal which has a greater bandwidth than the chroma component signals and is not GAMMA corrected, and GAMMA correcting the linear luminance component signal to provide a GAMMA-corrected luminance component signal having a greater bandwidth than the GAMMA-corrected chroma component signals.
