Abstract
Un aparato de reproducción para una señal de televisión en color registrada sobre un soporte de registro, cuyos sectores de período de línea individuales están alineados en pistas adyacentes sobre el portador de registro en una dirección perpendicular a las pistas y del cual al menos la señal de crominancia, modulada sobre una onda portadora y que contiene las señales de sincronismo de color, está grabada con polaridad periódicamente cambiada en dichos sectores al menos en una de dos pistas adyacentes, cuyo aparato comprende al menos un dispositivo para conmutar la polaridad de la señal reproducida en los sectores de período de línea individuales, cuya condición de conmutación esta controlada en pasos de conmutación consecutivos por un dispositivo de control, al cual está aplicada para obtener la magnitud de control al menos una señal de la frecuencia de sincronismo de línea, anulando la conmutación de polaridad el efecto de la conmutación de polaridad efectuada un circuito de identificación para la relación de fase entre cada dos señales de sincronismo de color, cuyo circuito está conectado a la vía de señal portadora de la señal reproducida de polaridad cambiada y que incluye un paso de comparación de fase, el cual recibe en una primera entrada las señales de sincronismo de color sin retardar y en una segunda entrada recibe las señales de sincronismo de color que han sido retardadas en un intervalo de tiempo predeterminado por medio de retardo, siendo dicho intervalo de tiempo igual a la duración de un período de línea para una señal de televisión en color de acuerdo con la norma NTSCe igual a la duración de dos períodos de línea para una señal de televisión en color de acuerdo con la norma PAL y cuya señal de salida está aplicada a un dispositivo de detección, el cual en el caso de una diferencia de fase entre las señales de sincronismo de color que han sido comparadas entre sí, suministra una señal por medio de la cual es cambiada la condición de conmutación de polaridaden un paso de conmutación.
