A method of composite decoding in which the input signal is converted into the frequency domain, and the symmetry of frequency components with respect to the subcarrier frequency is compared. The comparison is varied in dependence upon the frequency being processed. In this way, the separation can be adapted to suit known characteristics of different portions on the input spectrum. This is particularly useful for processing NTSC signals. The allocation of a particular component to chrominance may be biased in dependence upon a measure of the luminance information of the composite signal at a corresponding spatial frequency.

L'invention concerne un procédé de décodage composite consistant à convertir le signal d'entrée en domaine de fréquence, et à comparer la symétrie des composantes de fréquence avec la fréquence de la sous-porteuse. La comparaison est modifiée en fonction de la fréquence traitée. Il est ainsi possible d'adapter la séparation aux caractéristiques connues des différentes parties du spectre d'entrée, ce qui particulièrement utile pour le traitement de signaux NTSC. L'attribution d'une composante particulière à la chrominance peut être orientée en fonction d'une mesure des données de luminance du signal composite, à une fréquence spatiale correspondante.
