Abstract

L'invention concerne les magnétoscopes. Le dispositif de l'invention reçoit sur une borne d'entrée 1 un code de temps qui est enregistré sur une bande vidéo, et il fournit sur une borne de sortie 14 un signal qui indique si la fréquence d'image des signaux vidéo enregistrés est de 25 ou de 30 images par seconde. Cette discrimination est basée sur l'irrégularité dans l'alternance des numéros d'image pairs et impairs qui se manifeste dans le cas d'un signal à 25 images par seconde. Application aux magnétoscopes bistandard.
