Abstract

L'invention concerne un système numérique de haut-parleurs sans fil comprenant un dispositif de transmission audio servant à sélectionner et à transmettre des données audio numériques, ainsi que des haut-parleurs sans fil servant à recevoir les données et à diffuser le son. Le dispositif de transmission audio sélectionne les données audio numériques avec un signal d'horloge d'échantillonnage en provenance d'un disque compact stéréo ou de données DVD décodées. Le signal d'horloge d'échantillonnage cadence un élément générant des trames de données et fournit une protection contre les erreurs. Les messages d'état sont inclus dans les trames de transmission afin de commander numériquement les attributs des haut-parleurs, tels que le groupe de haut-parleurs, l'activation ou désactivation du sub-woofer et le volume du haut-parleur. Ces trames de transmission sont synchronisées dans un émetteur RF et transmises aux haut-parleurs. Le train de bits reçu et le signal d'horloge symbole sortant du récepteur RF dans chaque haut-parleur sont introduits dans un décodeur de trames et de protection contre les erreurs et un générateur de signaux d'horloge d'échantillonnage. Les données audio échantillonnées récupérées et le signal d'horloge d'échantillonnage sont introduits dans un dispositif de conversion dénumériseur et un sélecteur de canaux.
