Abstract:
A method of encoding a non-linear, color space video signal includes converting the non-linear video signal to a linear video signal, transforming the non-linear signal to produce a transformed non-linear signal, transforming the linear signal to product a transformed linear signal, using the transformed linear signal to determine errors, applying the errors to the non-linear, color space video signal to produce a compensated non-linear color space signal, and encoding the compensated signal.
