Abstract

Selon la présente invention, une unité de stockage (101) stocke un contenu à reproduire et une unité de calcul de temps de reproduction (102) calcule un temps de reproduction de contenu stocké dans l'unité de stockage (101). En outre, une unité d'entrée (103) reçoit une entrée d'informations de point de destination concernant un point de destination d'un corps mobile et une unité de calcul de temps de mouvement (104) calcule un temps de mouvement nécessaire pour que le corps mobile atteigne le point de destination en fonction des informations de point de destination entrées par l'unité d'entrée (103). Une unité de comparaison (105) compare le temps de reproduction au temps de mouvement. En fonction du résultat de la comparaison obtenu par l'unité de comparaison (105), une unité de définition (106) définit une vitesse de reproduction de contenu et une unité de reproduction (107) reproduit un contenu conformément à la vitesse de reproduction définie par l'unité de définition (106).
