(FR) SIMULATION DE CONNECTIVITE DOUBLE SENS POUR TRAIN DE DONNEES POUR PARTIES MULTIPLES
Abstract
(EN)
A host device (35) is disclosed. The host device includes a processor (38) and a control mechanism. The processor operates to receive primary and associated data, the associated data being targeted for different recipients, decode and separate the associated data from the primary data, and cause the associated data to be correspondingly rendered on separate hand held devices (200). The processor also operates the control mechanism to control a separate display apparatus to separately receive and render the primary data.
(FR)
L'invention concerne une unité centrale (35) comportant un processeur (38) et un mécanisme de commande. Ledit processeur est conçu pour recevoir des données primaires et associées, les données associées étant ciblées pour différents destinataires, pour décoder et séparer les données associées des données primaires, et induire le rendu correspondant des données associées sur des dispositifs portatifs séparés (200). Le processeur agit également sur le mécanisme de commande de sorte qu'un appareil d'affichage séparé reçoive et rende les données primaires.
