Title (EN) A THIN MULTIMEDIA COMMUNICATION DEVICE AND METHOD
(FR) PROCEDE ET DISPOSITIF DE COMMUNICATION MULTIMEDIA DU TYPE CLIENT MAIGRE
Abstract:
(EN) A communication system and method comprises endpoint devices (10, 11), each of which has one or more audio transducers (23-26) and a touch screen (29, 31). The devices (10, 11) are connected by a network (12) providing non-dedicated communication paths to servers (14, 15). An application (16, 17) is resident in each of the servers (14, 15) and has the ability to affect the image displayed on at least part of the screen (29). The server (14, 15) performs signalling for controlling an audio connection between the devices (10, 11). The touch screen (29, 31) is interactive and is able to initiate the audio connection. The application (16, 17) allows the screen (29) or each screen of devices (10, 11) participating in the audio connection to display the path of consecutive measured positions of a pointer (30) on the screen (29) from one or more of the connected devices (10, 11). The screen (29) is able to display an image supplied by a remote server or other apparatus after the audio connection has been initiated.
(FR) L'invention concerne un procédé et un système de communication comprenant des dispositifs d'extrémité (10,11) dotés chacun d'un ou plusieurs transducteurs audio (23-26) et d'un écran tactile (29, 31). Lesdits dispositifs (10, 11) sont connectés par un réseau (12) fournissant des voies de communication non spécialisées aux serveurs (14, 15). Une application (16, 17) réside dans chaque serveur (14, 15) et a la capacité de modifier l'image affichée sur au moins une partie de l'écran (29). Le serveur (14, 15) assure la signalisation pour la commande d'une connexion audio entre les dispositifs (10, 11). L'écran tactile (29, 31) est interactif et peut déclencher la connexion audio. L'application (16, 17) permet à l'écran (29) ou à chaque écran des dispositifs (10, 11) participant à la connexion audio, d'afficher le chemin des positions mesurées consécutives d'un pointeur (30) sur l'écran (29) à partir d'au moins un dispositif connecté (10, 11). L'écran (29) est capable d'afficher une image fournie par un serveur éloigné ou un autre appareil une fois la connexion audio déclenchée.
