Abstract

L'invention concerne un procédé de commande par rayonnement infrarouge. Ce procédé de commande consiste à envoyer au récepteur de l'appareil à commander un signal sous le forme d'un code d'impulsions pour lequel on utilise un code biphasé qui est interrogé à des intervalles de temps t0 , ce qui fournit une pondération binaire selon un profil binaire à 7 bits 2**0 à 2** 6, l'exploitation du code d'impulsions s'effectuant après un retard t1 . Application notamment à la télécommande d'appareils de télévision.The invention relates to an infrared radiation control method. This control method consists of sending to the receiver of the apparatus to be controlled a signal in the form of a pulse code for which a two-phase code is used which is polled at time intervals t0, which provides a binary weighting. according to a 7-bit binary profile 2 ** 0 to 2 ** 6, the pulse code is evaluated after a delay t1. Application in particular to the remote control of television devices.
