Patent

CA 2244356

A video database is indexed using the terms of closed-captioning which accompany the video components of the video database. When a query is run against the video database, a list of hits, corresponding to video components relevant to the query, are presented to the user by selecting a representative image from each video component in the hitlist and presenting the representative images to the user in an array of thumbnail images with the corresponding closed-captioned text.

Une base de données vidéo est indexée au moyen des sous-titres qui accompagnent ses composantes vidéo. Quand cette base de données vidéo est consultée, le système de l'invention présente à l'utilisateur la liste des coïncidences correspondant aux composantes vidéo qui se rapportent à la consultation en sélectionnant une image représentative dans chaque composante vidéo figurant sur cette liste et en présentant les images représentatives à l'utilisateur en un tableau d'images miniatures avec le sous-titre correspondant.
