Abstract: L'invention concerne un système pour le codage efficace de plans de bits de données de coefficients de transformation, telles que les données utilisées dans un système de codage vidéo. Les valeurs décimales pour les coefficients de transformation, par exemple dans un bloc de plusieurs coefficients, sont converties en valeurs binaires, chaque bit occupant un plan de bits correspondant, du bit le plus significatif au bit le moins significatif. Un bit de chaque coefficient est produit dans un plan de bits commun. Un indicateur ou un mot de code à un bit (tel que <= 0 >=) est utilisé pour le codage d'un ou plusieurs plans de bits exclusivement composés de zéros, alors qu'un autre indicateur à un bit (tel que <= 1 >=) est utilisé pour la désignation du premier plan non exclusivement composé de zéros suivant. Pour ce qui concerne le premier plan non exclusivement composé de zéros, une table de codage réduite est utilisée pour la production des mots de code suivant l'indicateur à un bit. La table de codage est de taille réduite du fait qu'un mot de code <= exclusivement constitué de zéros>= spécial n'est pas requis. De plus, l'utilisation d'un indicateur à un bit pour la désignation des plans de bits initiaux, exclusivement constitués de zéros permet la réduction du nombre de bits de codage requis par rapport aux systèmes de la technique antérieure dans lesquels des mots de code exclusivement constitués de zéros et multibits sont nécessaires. Un codeur (200) comporte une fonction de mot de code <= 0 >= (242), une fonction de mots de code <= 1 >= (244), une table réduite (246) et des tables classiques (248). Un décodeur correspondant (400) comprend une fonction de mot de code <= 0 >= (442), une fonction de mot de code <= 1 >= (444), une table réduite (446) et des tables classiques (448).
