Abstract

Selon la présente invention, des données de sources locales sont tout d'abord échantillonnées (20) à une fréquence d'échantillonnage originale et ensuite rééchantillonnées (30) à une première fréquence d'échantillonnage qui est égale à la fréquence d'encadrement permettant de transmettre lesdites données à la source éloignée. Les données de sources locales rééchantillonnées sont ensuite différées (40) par le temps de transmission (36) existant entre les sources de données locales et éloignées. Les données issues du relais éloigné qui sont rééchantillonnées (48) au niveau de la source éloignée à la première fréquence de rééchantillonnage (48) et les données rééchantillonnées (42) différées au niveau de la source locale sont ensuite rééchantillonnées (46) à la seconde fréquence de rééchantillonnage, à une fréquence d'échantillonnage originale, pour donner des données alignées au niveau de la source locale.
