Abstract

La présente invention permet de changer d'animateur (DJ) de manière adéquate et de recevoir une demande de musique. Ce dispositif de lecture (1) est capable de lire tout en recevant des données transférées à partir de multiples terminaux sans fil (3), et est équipé : d'une unité de communication sans fil (21) qui se connecte à un réseau de communication sans fil (NW) pour effectuer des communications sans fil avec les terminaux sans fil (3) ; d'une section d'établissement de liaison (61) qui établit des liaisons dédiées pour les terminaux sans fil (3) afin de transférer des données de musique depuis les terminaux sans fil (3) par l'intermédiaire du réseau de communication sans fil (NW) ; d'une section de restriction de connexion (62) qui limite les connexions par l'intermédiaire des liaisons dédiées à un certain nombre de terminaux sans fil (3) supérieur à un nombre prédéterminé ; et d'un moyen d'affichage de quantité de terminaux (26, 64) qui affiche le nombre de terminaux sans fil (3) avec lesquels des liaisons dédiées sont établies.
