Abstract

L"invention concerne un procédé et un système de transmission de données (21) à qualité d"image et de mouvement selectionnable par le destinataire. Les données sont décomposées en trames (figure 2), lesquelles peuvent être décomposées en bandes, chacune des bandes ajoutant des données à la bande précédente. Les trames et/ou bandes sont transmises individuellement ou en groupes à différentes vitesses sur différents canaux (figure 4). Chaque destinataire peut s"abonner aux canaux qui assurent le niveau désiré de qualité d"image et de mouvement pour la bande passante disponible pour chaque destinataire.
