Title
(EN) SYSTEM FOR INTERACTIVE TELEVISION
(FR) SYSTEME DE TELEVISION INTERACTIVE
Abstract
(EN)
A system and method for interactive television (ITV) includes presenting both TV channels and 'virtual channels' on an ITV (22). A virtual channel can be a Web page stored in memory (44) of the ITV (22) (or remote therefrom) and accessed by a microprocessor (46) in the ITV (22) when a user selects the virtual channel number using a conventional TV remote control (3). The particular Web page can be established based on consumer data, such as demographic data supplied by the consumer or consumer responses to prompts displayed along with a channel. The Web page associated with the virtual channel can be updated or changed by sending data to the ITV (22) through the VBI of a TV signal (26) or via the Internet (24), through a modem on the ITV (22).
(FR)
La présente invention concerne un système et un procédé permettant d'obtenir une télévision interactive (ITV). Selon cette invention, à la fois des chaînes de télévision et des « chaînes virtuelles » sont présentées sur une ITV (22). Une chaîne virtuelle peut être une page Web, enregistrée dans une mémoire (44) de l'ITV (22) (ou à distance de celle-ci) et accessible par un microprocesseur (46) situé dans l'ITV (22), lorsqu'un utilisateur sélectionne le numéro de la chaîne virtuelle, par utilisation d'une télécommande de télévision classique (30). La page Web particulière peut être établie sur la base de données concernant le client, telles que des données démographiques fournies par le client, ou de réponses du client à des messages affichés avec une chaîne. La page Web associée à la chaîne virtuelle peut être mise à jour ou modifiée, par envoi de données à l'ITV (22), par l'intermédiaire de l'intervalle de suppression de trame (vertical blanking interval : VBI) d'un signal (26) de télévision ou par Internet (24), par l'intermédiaire d'un modem sur l'ITV (22).
