Abstract

Dans un mode de réalisation de la présente invention, six canaux de télévision numérique terrestre sont spécifiés à titre de canaux à décaler, et du contenu diffusé sur lesdits canaux (par exemple, du contenu à regarder gratuitement qui est protégé contre la copie conformément aux règles "Dubbing 10" du Japon) est réglé pour être enregistré sur un lecteur de disque dur (HDD) pour un décalage normal. Également, un canal de télévision par satellite diffusé par l'intermédiaire d'un satellite de diffusion est spécifié à titre de canal supplémentaire à décaler, et du contenu diffusé sur ledit canal (par exemple, du contenu payant copiable une seule fois) est réglé pour être enregistré sur un HDD pour un décalage supplémentaire. Une première période de temps dans laquelle le premier décalage peut être effectué et une seconde période de temps dans laquelle le second décalage peut être effectué peuvent être réglées séparément.
