Abstract
(EN) The present invention relates to a method for transporting real-time data from a transmitter to a receiver on a radio packet communication network, said method comprising the steps of: generating, at said transmitter, real-time data frames, said time real-data frames comprising at least two bit portions; selecting said first bit portion and submitting it to a first modulation and coding scheme providing an error-resistance higher than an error-resistance threshold; selecting said second bit portion and submitting it to a second modulation and coding scheme providing an error-resistance lower than said error-resistance threshold; transmitting a first radio packet transmission unit corresponding to said first bit portion to said receiver; transmitting a second radio packet transmission unit corresponding to said second bit portion to said receiver, said second radio packet transmission unit being different from said first radio packet transmission unit.
(FR) L'invention concerne un procédé de transport de données en temps réel d'un émetteur-récepteur à un récepteur dans un réseau de communication radio par paquets. Ledit procédé consiste à générer audit émetteur-récepteur, des cadres de données en temps réel, lesdits cadres de données en temps réel comportant au moins deux sections de bit, sélectionner ladite section de bit et la soumettre à une première modulation et à un programme de codage fournissant une résistance aux erreurs supérieure à un seuil de résistance aux erreurs, sélectionner ladite section de bit et la soumettre à une seconde modulation et un programme de codage fournissant une résistance aux erreurs inférieure à un seuil de résistance aux erreurs, transmettre une première unité de transmission de paquets radio correspondant à ladite première section de bit audit récepteur, transmettre une seconde unité de transmission de paquets radio correspondant à ladite seconde section de bit audit récepteur, ladite seconde unité de transmission de paquets radio différant de ladite première unité de transmission de paquets radio.
