Abstract

L'invention met en application un canal de système de transmission de données acoustiques afin de communiquer avec des objets à distance, tels que des jouets ou d'autres appareils nouveaux. Des données de contrôle sont encastrées dans des données acoustiques qui sont diffusées vers un jouet. Ces données sont reçues par le jouet qui est situé à proximité d'un récepteur. On peut modifier le fonctionnement de ce jouet à réception des données encastrées. Ce récepteur peut consister en un appareil de télévision et les données peuvent être diffusées par l'intermédiaire d'un programme télévisé.
