A method of detecting video sequences involves creating on-the-fly candidate digital signatures uniquely characteristic of successive groups of frames in accordance with a predetermined algorithm. The candidate digital signatures are compared with at least one signature of a stored sequence created in accordance with the predetermined algorithm. A candidate is identified as corresponding to the stored sequence in the event of a positive match.
Cette invention se rapporte à un procédé pour détecter les séquences vidéo, qui consiste à créer à la volée des signatures numériques candidates qui, par leur nature unique, sont caractéristique de groupes successifs de trames en fonction d'un algorithme prédéterminé. Les signatures numériques candidates sont comparées à au moins une signature d'une séquence mise en mémoire, créée en fonction de l'algorithme prédéterminé. Un candidat est identifié comme correspondant à la séquence mise en mémoire en cas de correspondance positive.
