  • the Internet is a worldwide, decentralized conglomeration of computer networks.
  • the World Wide Web (hereinafter the "Web") was created in the early 1990' s, and is comprised of servers (computers connected to the Internet) having hypertext documents or Web pages stored therewithin. These Web pages are accessible by client devices (hereinafter “clients”) using browser programs (hereinafter “browsers”) utilizing the Hypertext Transfer Protocol (HTTP) and the Transmission Control Protocol/Internet Protocol (TCP/IP) .
  • HTTP treats characters, images, tables, and the like, as objects and provides various correlations between objects.
  • Exemplary browsers include Netscape Navigator ® (Netscape Communications Corporation, Mountain View, CA) and Internet Explorer ® (Microsoft Corporation, Redmond, WA) .

  • FTP File Transfer Protocol
  • a Web page using a standard page description language known as HyperText Markup Language (HTML) , may display text and graphics, and may also play sound, animation, and video clips.
  • HTML provides basic document formatting and allows a Web page developer to specify hypertext links (conventionally manifested as highlighted text) to other servers and files.
  • a URL Uniform Resource Locator
  • a URL is a standard addressing technique for identifying information resources on the Internet.
  • a URL is conventionally an alphanumeric character string that identifies both the Web page and the server in which the Web page is located.
  • the specifications for URLs are governed by RFC1738 which is one of the official Request for Comments documents prepared by the Internet Engineering Task Force (IETF) .
  • IETF Internet Engineering Task Force

Abstract

L'invention concerne des dispositifs de communication, tels que des assistants numériques personnels (ANP) dotés de fonctionnalités de communication radiotéléphonique, d'accès et d'informations d'affichage provenant d'un serveur Internet par balayage d'une URL à code barres ou alphanumérique affichée sur différents supports. Après avoir déterminé si l'information scannée est une URL, on peut établir la communication client-serveur avec le serveur identifié par l'URL. L'information transmise par le serveur est affichée sur le ANP via un navigateur.
