Abstract

La presente invención se refiere a mejoras a aparato reproductor de videodiscos, que incluye un aparato de captación para recuperación de un disco, cuando el aparato de captación está en la posición de reprodución, ondas portadoras sujetas a modulación en frecuencia, de acuerdo con una señal de video compuesta que ocupa una banda de frecuencia predeterminada; que inclye: un aprato de demodulación de frecuencia que responde a una salida de onda portadora del aparato de captación, un conjunto de circuitos procesadores de señales que responden normalmente a la salida de señal demodulada del aparato de demodulación de frecuencia, un retardador de señales que responde normalmente a la salida de señal demodulada del aparato de demodulación de frecuencia, un detector de frecuencia acoplado al aparato de demodulación de frecuencia, un generador de impulsos; caracterizadas por un circuito de conmutación que responde a la salida del generador de impulsos de indicación de defectos para hacer que el generador de impulsos de desarrollo de señal de video compuesta de salida, responda a la señal de video compuesta, retardada en vez de la salida de señal demodulada del aparato de demodulación de frecuencia, durante la ocurrencia de un impulsor de indicación de defecto; un generador de señal de control que responde a la salida del generador de impulsos de indicación de defecto, para iniciar el desarrollo de una señal silenciadora, cuando la duración de un impulso de indicación de defecto excede un tiempo predeterminado; y un circuito de control para utilizar la señal silenciadora para inhibir el desarrollo de la señal de video compuesta de salida, mediante el conjunto de circuitos de procesamiento de señales.
