Abstract

L'appareil comprend des moyens de réception R de signaux numériques entrants, des moyens de mémorisation 10, 11 des signaux numériques entrants, reliés aux moyens de réception, des moyens 14 générateurs d'adresse d'écriture servant à causer la mémorisation des signaux numériques entrants dans les moyens de mémorisation, dans un premier ordre, des moyens 17 générateurs d'adresse de lecture servant à causer la lecture des signaux numériques contenus dans les moyens de mémorisation, dans un deuxième ordre différent du premier. Des moyens de commande servent à relier successivement et sélectivement aux moyens de mémorisation 10, 11 les moyens 14 générateurs d'adresse d'écriture et les moyens 17 générateurs d'adresse de lecture, et des moyens d'enregistrement sont reliés aux moyens de mémorisation de manière à enregistrer sur un support d'enregistrement les signaux numériques lus dans les moyens de mémorisation. Application, notamment, à l'enregistrement de signaux vidéo sur bande magnétique.
