Dans les récepteurs de télévision en couleurs [...], après la séparation des signaux-son et des signaux-image, les composantes de chrominance sont aiguillées vers leurs canaux respectifs pour être démodulées, décodées. [...] L'orientation des signaux est obtenue à l'aide de "lignes d'identification", c'est-à-dire de signaux particuliers qui permettent de bloquer la voie de chrominance lorsque les signaux [...] ne sont pas appliqués sur leur voie propre [...]. Ces signaux d'identification modulent la sous-porteuse et sont émis durant le temps du palier de suppression de trame qui suit les impulsions d'égalisation. 3, record 1, French, - impulsions%20d%27%C3%A9galisation
