Abstract

Un téléspectateur appuie sur un bouton spécifique d'un boîtier de télécommande (21) pour tenter d'acheter du mobilier (32) vu dans une scène (31) telle qu'une pièce de théâtre ou un film vu sur l'écran d'un récepteur de télévision (105). Un signal de télécommande émis par le boîtier (21) aboutit au récepteur, ce qui fait qu'une description (33) du meuble (32) vu dans la scène (31) vient s'afficher. Le téléspectateur décide s'il veut effectivement acheter le meuble (32) sur la base de la description (33). Lorsqu'il décide d'acheter le meuble (32), le téléspectateur appuie sur le bouton d'achat de la télécommande (21) de façon à envoyer à l'entreprise de commerce électronique un ordre d'achat portant sur le meuble (32), lequel ordre est accompagné de l'identificateur d'utilisateur. Une fois que l'entreprise de commerce électronique a pris en compte l'ordre d'achat accompagné de l'identificateur de l'utilisateur, le récepteur de télévision affiche une information confirmant que l'ordre d'achat a bien été accepté.
