(FR) CODAGE VIDEO

Abstract:

(EN)This invention relates to a system for compression of video sequences that is using motion compensated prediction. The key part of such system is motion vector field coding. The goal of motion vector field coding is to minimize the number of bits necessary for representation of the motion vector field while retaining at the same time very low prediction error. This invention discloses new matrix operations in the motion analyser of the motion field coder.
(FR)L'invention concerne un système de compression de séquences vidéo utilisant la prévision compensée de mouvement. Un tel système repose essentiellement sur le codage d'un champ vectoriel de mouvement. Le codage du champ vectoriel de mouvement a pour but de minimiser le nombre de bits nécessaires pour la représentation du champ vectoriel de mouvement, tout en n'ayant qu'une très faible erreur de prévision. L'invention décrit de nouvelles opérations matricielles dans l'analyseur de mouvement du codeur de champ de mouvement.
