A method for processing a broadcast video signal includes identifying a first advertising component within the video signal; creating control information based on predetermined characteristics of the first advertising component; and recording the video signal and the control information to form an encoded video signal, which is arranged in such a manner that a second advertising component is substitutable for the first advertising component based on a playback status of the encoded video signal.
La présente invention concerne un procédé pour traiter un signal vidéo diffusé. Ce procédé consiste à identifier un premier composant d'annonce publicitaire dans le signal vidéo, à créer des informations de commande, sur la base de caractéristiques prédéfinies du premier composant d'annonce publicitaire, puis à enregistrer le signal vidéo et les informations de commande, afin de former un signal vidéo codé qui est conçu de telle manière qu'un second composant d'annonce publicitaire peut remplacer le premier composant d'annonce publicitaire, sur la base d'un état de lecture du signal vidéo codé.
