(EN) A MULTIMEDIA DIRECT COMMUNICATION SYSTEM LINKED WITH HTTP PROTOCOL
(FR) SYSTEME MULTIMEDIA DE COMMUNICATION DIRECTE ASSOCIE A UN PROTOCOLE HTTP
Abstract
(EN)
A multimedia direct communication system linked with http protocol, which comprises application programs and a Web server, wherein the application programs are installed into a plurality of client personal computers (PCs), reside in the PCs such that they are displayed for many hours on the PCs occupying a part of the space on the display of the PCs, and are linked at all times with a Web server via http; the Web server has a CGI interface and is connected to each of the PCs through communication circuits to execute the http communication programs and applications; and each client can transfer (chat) electronic mails with each other in pseudo-real time via Internet and/or Intranet using the application programs.
(FR)
On décrit un système multimédia de communication directe associé à un protocole http, qui met en oeuvre des programmes d'application et un serveur Web. Les programmes d'application sont installés dans plusieurs ordinateurs personnels de clients (OP), affichés pendant plusieurs heures à l'écran desdits ordinateurs dont ils occupent une partie de l'espace, ces programmes étant reliés en permanence à un serveur Web grâce à un protocole http. Le serveur Web, qui comprend une interface CGI, est connecté à chaque OP par des circuits de communication pour exécuter les programmes de communication http. Les clients peuvent envoyer les uns les autres des messages électroniques (causerie) en temps pseudo-réel, via Internet et/ou l'intranet, au moyen desdits programmes d'application.
