Abstract

L'invention est un processeur vidéo servant à traiter un premier et un second signaux vidéo composites analogiques et à produire un signal vidéo analogique de sortie. Ce processeur vidéo comporte un décodeur vidéo et un réducteur qui sont utilisés pour convertir le second signal vidéo composite analogique en un signal vidéo numérique réduit. Le processeur vidéo comprend également un codeur vidéo servant à convertir le signal vidéo numérique réduit en un troisième signal vidéo composite analogique. Des circuits de synchronisation sont incorporés au processeur pour synchroniser le premier et le troisième signaux vidéo composites analogiques. Le processeur vidéo comprend également un multiplexeur vidéo composite servant à combiner le premier et le troisième signaux composites analogiques pour produire un signal vidéo composite analogique de sortie qui est constitué d'une partie du premier signal vidéo analogique et d'une partie du troisième signal vidéo analogique.
