Abstract

L'invention concerne les procédés et appareils d'échantillonnage de signaux. Elle se rapporte à un procédé qui comprend le prélèvement d'un certain nombre d'échantillons, pendant chaque intervalle d'échantillonnage successif, et la sélection, comme représentant cet intervalle, d'un échantillon qui présente l'écart maximal par rapport à l'échantillon choisi pour l'intervalle immédiatement précédent d'échantillonnage. Application à la compression des données vidéo par prélèvement d'échantillons très représentatifs.
