Abstract

L'invention concerne un dispositif et un procédé correspondant permettant de corriger des erreurs dans un train de données qui comprend des données utilisateur codées en mots de code long distance (LDC), des données de commande codées en mots de sous-code indiquant des rafales (BIS) et des données SYNC, les mots LCD et BIS étant alternativement agencés en grappes physiques commençant avec les données SYNC. Afin de s'assurer que le résultat d'une correction d'effacement peut être prédit et que cette correction d'effacement est compréhensible et d'utilisation facile, un dispositif prévu comprend: une unité de séparation (122) permettant de séparer les mots LDC et les mots BIS du train de données, un décodeur LDC (129) permettant de décoder les mots LDC et de corriger les erreurs et les effacements dans lesdits mots LDC, un décodeur BIS (125) permettant de décoder les mots BIS et de détecter les erreurs BIS dans lesdits mots BIS, un détecteur SYNC (121) permettant de détecter les données SYNC et les erreurs SYNC dans lesdites données SYNC, une unité de commande (126) permettant de marquer des effacements afin de décoder les mots LDC en fonction des erreurs BIS et des erreurs SYNC par marquage d'emplacements dans les mots LDC adjacents aux erreurs BIS et/ou aux erreurs SYNC comme effacements dépendant de paramètres de commande qui déterminent le comportement de la correction d'effacement du décodeur LDC.
