In a wireless network environment, a method of transmitting data from a source device to a set of sink devices, the method comprising the steps of: (a) initially the source device broadcasting packet data collectively to each of the sink devices; (b) the sink devices collecting packet data and identifying missing packets that have been missed; (c) upon a sink device detecting a missed a packet, the sink device separately requesting the transmission of the missed packet by the source device; and (d) the source device separately sending missed data packets.

Dans un environnement de réseau sans fil, l'invention concerne un procédé de transmission de données, d'un dispositif source vers un ensemble de dispositifs récepteurs. Le procédé comporte les étapes suivantes: (a) le dispositif source diffuse initialement les données en paquets collectivement vers chacun des dispositifs récepteurs; (b) les dispositifs récepteurs collectent les données en paquets et identifient les paquets manquants; (c) lorsqu'un dispositif récepteur détecte un paquet manquant, ce dispositif demande séparément la transmission, par le dispositif source, du paquet manquant; et (d) le dispositif source envoie séparément les paquets de données manquants.
