Abstract

L'invention a pour objet un dispositif qui reçoit toutes les images visualisées sur l'écran d'un récepteur de télévision sous forme d'images immobiles, reçoit des sons, si nécessaire, et visualise les images immobiles et reproduit les sons. Une image immobile provenant d'un terminal de sortie vidéo du récepteur de télévision est reçue, numérisée et enregistrée dans une mémoire d'images. L'image immobile numérisée enregistrée dans une mémoire d'images est convertie en une image analogique et fournie au terminal d'entrée vidéo du récepteur de télévision. Le dispositif peut également être pourvu d'un dispositif d'enregistrement de sons numérique qui reçoit les signaux sonores provenant du terminal de sortie sonore du récepteur de télévision, les numérise, enregistre les signaux numériques dans une mémoire de sons, convertit le signal enregistré en signaux analogiques et fournit les signaux sonores analogiques au terminal d'entrée sonore du récepteur de télévision. En outre, ce dispositif peut intégrer un dispositif de mémorisation externe dont le support de mémorisation, tel qu'un disque souple, peut stocker des données d'images immobiles et des données sonores enregistrées en mémoire.
