Abstract

Des circuits vidéo (204) sont agencés de façon à acheminer des signaux vidéo séquentiels, habituellement sous forme de séquences entrelacées, chaque séquence étant séparée par un intervalle de suppression de trame. Des circuits de données (203) sont agencés pour acheminer de façon aléatoire des données d'images adressables, sans inclure l'intervalle de suppression de trame. Le système de traitement (202) est conçu pour permettre la conversion entre données vidéo et données désignées par des adresses, assurant ainsi le transfert entre circuits vidéo et circuits de données à une cadence au moins égale à la cadence vidéo. Les données peuvent être lues au moyen d'un enregistreur vidéo numérique et enregistrées en continu à la cadence vidéo dans une mémoire locale, en format compatible avec l'environnement désigné.
