Abstract

Perfeccionamientos en aparatos para sistemas de procesamiento de señales de vide, que comprenden medios para reproducir una imagen en color en respuesta a componentes de luminancia y crominancia representativos de l imagen de dicha señal de vide, comprendiendo el componente de luminancia, que es susceptible a transiciones rápidas de amplitud, componentes de alta freciencia dentro de la gama de frecuencias de crominancia, comprendiendo dichos sistemas también un canal de crominancia para utilizar el componente de crominancia, medios para acoplar de una forma selectiva señales de video dentro de la gama de frecuencias de crominancia al canal de crominancia.
