Abstract

L'invention concerne un procédé et un appareil de traitement d'affichage, ainsi qu'un système d'affichage, le procédé consistant à : recevoir des contenus d'affichage à partir d'un terminal; et à envoyer respectivement les contenus d'affichage à une pluralité d'appareils d'affichage pour être affichés. Par adoption des solutions techniques mentionnées ci-dessus de la présente invention, on peut résoudre le problème selon lequel les solutions d'affichage existantes peuvent uniquement utiliser un affichage biunivoque et selon lequel il n'y a pas de façon de réaliser un affichage co-univoque (c'est-à-dire, afficher les contenus d'affichage d'un terminal dans une pluralité d'appareils d'affichage) dans la technologie associée, permettant ainsi de réaliser l'affichage des contenus d'affichage du dispositif source sur une pluralité d'appareils d'affichage.
