Title
(EN) WIRELESS SIGNAL TRANSMISSION SYSTEMS, METHOD AND APPARATUS
(FR) SYSTEMES, PROCEDE ET DISPOSITIF DE TRANSMISSION SANS FIL DE SIGNAUX
Abstract
(EN)
A local wireless audio system (22) where transmissions are conducted over the 900 MHz band to a portable receiver unit (22) supported on the headband of a stereo headphone unit (210). The receiver unit serves to downconvert the 900 MHz signal to a local signal which is received by an FM receiver which receives and reproduces the audio.
(FR)
Système (22) audio local sans fil dans lequel les transmissions sont effectuées sur la bande de 900 MHz vers une unité (22) réceptrice portative, supportée par la bande serre-tête d'une unité (210) casque stéréo. L'unité réceptrice sert à changer la fréquence du signal de 900 MHz en une fréquence de signal local reçue par un récepteur F.M. qui reçoit et reproduit les signaux audio.
