Abstract

Selon l'invention, les technologies classiques ont un problème en ce que des « scènes d'utilisation d'informations de recommandation sur la prémisse d'un réseau » (lequel de multiples dispositifs d'enregistrement/reproduction connectés à un réseau devrait utiliser des informations de recommandation) ne sont pas prises en considération. Par exemple, l'exécution d'une commande de manière à enregistrer des informations de recommandation concernant un dessin animé d'enfants sur un enregistreur HDD installé dans la chambre des parents, ou autre, n'est pas considéré comme une recommandation appropriée. De manière à résoudre le problème susmentionné, la présente invention concerne un dispositif serveur qui est équipé de fonctions pour conserver/gérer des informations qui indiquent des utilisations respectives de multiples dispositifs AV qui sont connectés au moyen d'un réseau, par exemple « installé dans la chambre des enfants », « l'utilisateur primaire est âgé de 40 ans », « l'heure d'utilisation principale est comprise entre 13h00 et 16h00 », et pour effectuer une commande pour une visualisation ou un enregistrement par utilisation du dispositif AV installé dans la « chambre des enfants » si le contenu recommandé par les informations de recommandation est un « dessin animé pour enfants ».
