Title (EN) HYBRID VIDEO RECOGNITION SYSTEM BASED ON AUDIO AND SUBTITLE DATA
(FR) SYSTÈME DE RECONNAISSANCE VIDÉO HYBRIDE BASÉ SUR DES DONNÉES AUDIO ET DES DONNÉES DE SOUS-TITRES
Abstract:
(EN) A system (10, 50) a»d.method (20, 32, 85, 118) where a second screen app (15) on a user device (14, 52-54) "listens" to audio clues from a video playback unit (56) that is currently playing an. audio-visual content. The audio clues include background audio and human speech content The background audio is converted into Locality Sensitive Hashtag (LSH) values. The human speech content is converted into an array of text data, The LSH values are used by a server (12, 62) to find. a. ballpark estimate of where in the audio-visual content the captured background audio is from. This ballpark estimate identifies a specific video segment. The server then matches dialog text array with pre-stored subtitle information (for the identified video segment) to provide a more accurate estimate of the current play-through location within that video segment. A timer-based correction provides additional accuracy. The combination of LSH-based and subtitle-based searches provides fast and accurate estimates of an audio- visual program's play-through location.
(FR) La présente invention concerne un système (10, 50) et un procédé (20, 32, 85, 118) dans lesquels une seconde application d'affichage (15) sur un dispositif utilisateur (14, 52-54) « écoute » des indications audio provenant d'une unité de lecture vidéo (56) qui lit un contenu audiovisuel. Les indications audio contiennent un fond sonore et un contenu de parole humaine. Le fond sonore est converti en valeurs de mots-dièses sensibles à la position (LSH). Le contenu de parole humaine est converti en une matrice de données de texte. Un serveur (12, 62) utilise les valeurs LSH pour trouver une estimation approximative de l'emplacement dans le contenu audiovisuel d'où provient le fond sonore capturé. Cette estimation approximative identifie un segment vidéo spécifique. Le serveur met alors en correspondance la matrice de texte de dialogue et des informations de sous-titres prémémorisées (pour le segment vidéo identifié) de façon à obtenir une estimation plus précise de l'emplacement actuel de l'enregistrement de progression personnelle dans ce segment vidéo. Une correction basée sur un minuteur permet une précision accrue. La combinaison des recherches basées sur les LSH et des recherches basées sur les sous-titres permet des estimations rapides et précises d'un emplacement d'un enregistrement de progression personnelle d'un programme audiovisuel.
