H.264 est la dernière norme de compression vidéo HDTV, qui offre une amélioration significative de l'efficacité du codage au prix d'une énorme complexité de calcul. Après transformation et quantification, si tous les coefficients des données résiduelles du bloc sont nuls, ce bloc est appelé bloc tout nul (AZB). À condition qu'un AZB puisse être détecté tôt, le processus de transformation et de quantification sur un AZB peut être ignoré, ce qui réduit considérablement les calculs redondants. Dans cet article, une analyse théorique est effectuée pour déterminer la condition suffisante pour la détection d’AZB. En conséquence, une somme partielle des différences absolues (SAD) basée sur 4

Abstract: H.264 is the latest HDTV video compression standard, which provides a significant improvement in coding efficiency at the cost of huge computation complexity. After transform and quantization, if all the coefficients of the block's residue data are zero, this block is called all-zero block (AZB). Provided that an AZB can be detected early, the process of transform and quantization on an AZB can be skipped, which reduces significant redundant computations. In this paper, a theoretical analysis is performed for the sufficient condition for AZB detection. As a result, a partial sum of absolute difference (SAD) based 4
