Abstract

La présente invention concerne un dispositif de réduction de défauts de transmission dans un dispositif de transmission de données en parallèle. Des données étant transmises entre une entrée 1 et une sortie 10 par l'intermédiaire de trajets en parallèle passant par des mémoires 1 à n, la présente invention prévoit des sélecteurs de données tournants S1l à S 1n avant les mémoires et S2l à S2n après les mémoires. En cas de défaut de l'une des mémoires, les commutateurs tournants sont entraînés en rotation pour appliquer la ligne en défaut à la mémoire n correspondant au bit le moins significatif. Ainsi, l'influence du défaut est minimisée. Application aux stations d'émission de télévision.
