Abstract

Dispositif de recherche de composition musicale (101) inclus dans un système de navigation pour automobile. Les compositions musicales stockées sur un disque dur du système de navigation de l’automobile ont été toutes reproduites. En se référant aux compositions musicales reproduites, une nouvelle composition musicale à reproduire est recherchée. Le dispositif de recherche de composition musicale (101) comprend une section de réception (201) pour recevoir des informations sur le morceau spécifié par l’utilisateur, une section de recherche (202) effectuant une recherche dans une base de données contenant des données musicales sur des compositions musicales, pour trouver celle correspondant ou en relation avec le morceau spécifié, et une section de transmission (203) transmettant les résultats de la recherche. Grâce à ceci, il est possible d’obtenir du dispositif de recherche de composition musicale (101) des données musicales sur une composition musicale ne figurant pas sur le disque dur.
