Abstract

Perfeccionamientos en aparatos para la televisión en color, caracterizándose por ser del tipo en que los detalles "cromáticos" están contenidos en una sub-portadora y en el que se presenta una descarga sincronizadora de frecuencia de la subportadora, durante los intervalos comprendidos entre el final de un impulso de sincronización y el comienzo de la línea de imagen subsiguiente y por contener una válvula, medios para aplicarle señales de televisión como corriente de entrada, un circuito restaurador de corriente continua conectado a dicha válvula, un interruptor electrónico en un circuito alimentado con señales de salida de corriente continua restaurada, procedentes de la válvula, medios electrónicos para cerrar el interruptor durante los períodos de fijación de las señales de televisión y medios para reintroducir como corriente de entrada superimpuesta a dicha válvula el voltaje dependiente del nivel del voltaje de salida de la válvula cuando el interruptor está cerrado.
