Abstract

Procédé de traitement de signaux vidéo composites pour la production d'effets spéciaux. Le signal vidéo composite analogique est digitalisé par codage séparé, puis écrit dans des memoires numériques à accès aleatoire 4, 6. Une commande d'adresse 7 différente de celle adoptée pour l'écriture permet, lors de la lecture des mémoires numériques, et après décodage approprié, de comprimer, symétriser, reproduire, distordre ou déformer à volonté des images de télévision couleur.
