Abstract

L'invention concerne un procédé permettant de réaliser des pistes audio multimédia pour un système de diffusion multimédia mobile. Ce procédé comprend une étape consistant à envoyer des données audio d'une voie de communication comprenant au moins une piste audio. Ensuite, le système de diffusion multimédia mobile divise les données audio en un en-tête de données audio et en N unités audio. L'en-tête de paquet comprend le nombre de pistes de chaque unité audio. Puis, le procédé consiste à envoyer les données audio dans au moins une voie de données ayant servi à la distribution pour la voie destinée à la transmission. Une synchronisation peut être insérée dans les unités audio pour une séparation. L'invention est de préférence utilisée dans un système de diffusion multimédia mobile pouvant envoyer des données audio d'une voie comprenant au moins une piste audio. Ainsi, le système de l'invention présente une efficacité de transmission supérieure à celle d'un système de l'état de la technique.
