Patent

CA 2449032

Systems, methods, and computer products that facilitate transmission of information used for fast and responsive video and audio playback at non- standard, trick mode speeds. An embodiment of the present invention uses low resolution, compressed, and independent frames derived from the encoded digital video or audio information to facilitate the operation of user- requested VTR-like speed change functions associated with digital video and digital audio frames. The present invention greatly simplifies locating specific frames in a video or audio presentation for purposes such as fast forward and fast reverse scanning that is typically used in digital editing.

L'invention concerne des systèmes, des procédés et des produits informatiques facilitant la transmission d'informations propres aux fonctions vidéo en mode rapide et réactif et la lecture audio à des vitesses non standard en mode d'enrichissement. Selon une variante, on utilise des trames à faible résolution, comprimées et indépendantes, dérivées de l'information numérique vidéo ou audio codée, pour faciliter la mise en oeuvre des fonctions de variation de vitesse demandées par l'utilisateur, du type magnétoscopie, en liaison avec les trames numériques vidéo et audio. Cela permet de simplifier considérablement la localisation de trames spécifiques dans une présentation vidéo ou audio, par exemple en cas de défilement rapide avant/arrière, généralement utilisé pour les besoins du montage numérique.
