Patent

CA 2199485

A video recording and playback device (10) incorporates a processor (114) for processing the video signal to detect the presence of commercial messages. Video and audio event detectors (102, 104) detect the presence of events in the signal as it is recorded. The timing relationship of the detected events is analyzed to classify the video segments between events as program material or as commercial messages. After a program is recorded, control marks are generated (132) to indicate the beginning and end of commercial groups so that they will be skipped during subsequent replay of the recorded program.

Un dispositif vidéo (10) d'enregistrement et de lecture comprend un processeur (114) conçu pour traiter le signal vidéo et détecter la présence de messages publicitaires. Des détecteurs d'événements audio et vidéo (102, 104) détectent la présence d'événements dans le signal lors de son enregistrement. La relation temporelle des événements détectés est analysée pour classer les segments vidéo entre les événements comme faisant partie de l'émission ou comme correspondant à des messages publicitaires. Après avoir enregistré le programme, on génère des marques de commande (132) pour indiquer le début et la fin des pages de publicité, de manière que ces dernières soient sautées lorsque le programme est relu.
