Abstract

Mejoras introducidas en el objeto de la patente principal nº 379.687 por "Decodificador para reproducción en color en alta fidelidad de una señal de color sistema PAL" en la que para obtener las señales de diferencia de color de frecuencia portadora o video (o crominancia) de una señal de cromaticidad PAL que alterna de línea a línea con relación a la dirección en que se cuenta el ángulo de fase, se quita el error de fase que ha sido producido a lo largo del camino de transmisión y de la señal de cromaticidad alternada, con la ayuda de un decodificador de fase, se deriva una señal de fase independiente de la amplitud alternándose la dirección en que se cuenta esta señal de línea a línea, y la señal de fase alternada de esta forma se retarda en un dispositivo de fase conocido per se en alrededor de un período de línea.
