Abstract

La présente demande a trait au domaine technique des communications. Sont divulgués un procédé et un appareil de transmission de données. Le procédé comprend les étapes suivantes : un dispositif mandataire reçoit des premières données codées envoyées par une station source de données, les premières données transportant un premier identifiant ; le dispositif mandataire duplique les premières données, de façon à obtenir N éléments de premières données, le dispositif mandataire étant connecté à une pluralité de terminaux, et N terminaux parmi la pluralité de terminaux demandent les premières données sur la base du premier identifiant, N étant un nombre entier supérieur ou égal à 2 ; et le dispositif mandataire envoie les premières données à chacun des N terminaux. Dans la présente demande, des premières données sont dupliquées et transférées au moyen d'un dispositif mandataire, et permettent ainsi même s'il existe une pluralité de terminaux demandant l'acquisition des premières données, d'éviter à une station source de données de devoir envoyer les premières données de multiples fois, ce qui permet de réduire le nombre de transmissions des premières données par la station source de données, de réduire la consommation de bande passante de transmission de la station source de données, et de réduire le retard et la latence se produisant dans un service correspondant aux premières données.
