Abstract
L'invention concerne un procédé et un système pour augmenter la capacité de transmission numérique dans un système de distribution coaxial arborescent utilisant des amplificateurs de signal TV (650). Plus précisément, plusieurs bandes séparées sont utilisées dans un câble d'alimentation principal (624), bandes décalées en fréquence et appliquées à plusieurs réseaux de distribution coaxiale locaux. Dans le mode de réalisation préféré de l'invention, chaque réseau de distribution coaxial local (762, 766 et 770) utilise la même paire de fréquences d'amont et d'aval (116 et 120). L'utilisation de paires identiques de fréquences d'amont et d'aval permet l'utilisation d'une seule interface de données d'utilisateur final non syntonisante normalisée (modem client 408), pouvant être connectée à un réseau de distribution coaxial local, quel qu'il soit.
