Abstract

Selon l'invention, la distribution de documents sonores ou visuels sur une liaison de télécommunications (2) à partir d'un serveur (1) à un terminal (3) est effectuée au moyen de la division du document en une séquence de sous-fichiers, chacun de ces sous-fichiers étant demandé individuellement par le terminal, qui commande ainsi le débit de distribution. Une disposition peut être prise pour basculer entre d'autres ensembles de sous-fichiers représentant d'autres modes de distribution ou des débits de données.
