Abstract

Système de télécommande pour dispositif de commande de récepteur de télévision. Le système utilise une émission de rayons infrarouges pour transmettre une impulsion de données de rayons infrarouges à chaque front d'un signal de durée d'impulsion comprenant un motif codé de 0 et de 1 binaires qui sont formés par des impulsions de longueurs respectives différentes. Le signal de durée d'impulsion original peut être reconstitué dans un récepteur par un élément bistable qui réagit aux impulsions de données infrarouges. Comme la forme d'onde de modulation régénérée pourrait être en opposition de phase avec la forme d'onde de modulation originale, la séquence d'impulsions de données est transmise deux fois et une impulsion de donnée supplémentaire est transmise entre des transmissions successives de telle sorte que l'une ou l'autre des deux formes d'onde de modulation régénérées soit nécessairement en phase avec la forme d'onde de modulation originale. Application : fabrication de télévision.
