Title (EN) H.264 QUANTIZATION
(FR) QUANTIFICATION H.264
Abstract: front page image
(EN)Low complexity (16 bit arithmetic) H.264 video compression (Fig.1a, input macroblock) replaces a single quantization table (Fig.1a, input quantization parameter) for all quantization parameters with multiple quantization tables (Fig.1a, quantization) and thereby equalizes quantization shifts and round-off additions (Fig.1a, encoded quantized transformed macroblock); this eliminates the need for 32- bit accesses.
(FR)Une compression vidéo H.264 à faible complexité (16 bits arithmétiques) remplace une table de quantification unique pour tous les paramètres de quantification au moyen de tables de quantification multiples, ce qui permet ainsi d'égaliser les décalages de quantification ainsi que les additions arrondies au plus près. Ainsi, le besoin d'accéder à 32 bits est éliminé.
