Abstract
A method for determining a chroma gain for a modulated chroma signal, comprises the steps: receiving the modulated chroma signal; generating a first chroma gain as a function of a color burst of the received modulated chroma signal; generating a second chroma gain as a function of a peak amplitude of the modulated chroma signal; and determining a final chroma gain for the received modulated chroma signal as a function of the first generated chroma gain and the second generated chroma gain, wherein the determined chroma gain is applied on the modulated chroma signal.
