By inserting weighting data, for example in the form of two bits, which already allow four different weight classes, the weighting of the stream can be taken into account in the billing. Additionally or alternatively, data may also be provided in the acknowledgment data record which identify the requested data stream or contain information about it, which allows a subsequent assessment of the significance, eg in the context of billing.

Abstract

L'invention concerne un procédé dans un système de distribution de données (10) pour la distribution décentralisée de flux de données en temps réel au moyen d'un système pair à pair entre des terminaux de données (14, 16, 18) reliés par un réseau de communication, procédé selon lequel des ressources de mise à disposition des terminaux des utilisateurs sont utilisées pour générer les flux de données en temps réel. Selon l'invention, les flux de données en temps réel (30) sont divisés sous forme de paquets de données; les paquets de données sont stockés dans une mémoire du terminal de l'utilisateur (16) en relation temporelle avec la transmission; les paquets de données sont transmis du terminal de l'utilisateur (16) à un autre utilisateur (18) sur demande; un ensemble de données d'accusé de réception (32) est renvoyé à l'utilisateur (16) par le terminal de données de l'autre utilisateur (18) en réponse à la réception des paquets de données, cet ensemble contenant des informations concernant les données mises à disposition et l'identité du terminal de données de l'utilisateur (16) mettant à disposition les données; les ensembles de données d'accusé de réception reçus pour des mises à disposition sont transmis (34) par l'utilisateur (16) au système de distribution de données; l'utilisateur (16) reçoit du système de distribution de données une compensation pour les données mises à disposition conformément aux informations contenues dans les ensembles de données d'accusé de réception. Ce procédé permet d'inciter les utilisateurs d'un système de distribution de données à mettre à disposition de la capacité de transmission de données sans exclure les utilisateurs qui ne le font pas.
