Abstract
Un método de grabar y/o reproducir señales de televisión en colores, con arreglo al cual los sectores individuales de periodo de linea en pistas contiguas del soporte de registro se alinean unos respecto a otros en dirección perpendicular a las pistas y en por lo menor una de dos pistas contiguas la polaridad de las señales que se van a registrar y que Están aplicadas por modulación a una portadora, se cambia periódicamente en los periodos de linea, en tanto que para las señales que en el espectro de frecuencias presentan máximos separados a distancias equivalentes a la mitad de la frecuencia de lineas, las señales de dos periodos de linea consecutivos de una pista respecto a los dos periodos de linea contiguos a estos de una pista contigua por parejas presentan alternativamente las mismas y distintas polaridades y para las señales que en el espectro de frecuencias presentan máximos separados a una distancia equivalente a la frecuencia entera de lineas, las señales de los periodos de lineaconsecutivos individuales de pistas contiguas presentan alternativamente las mismas y distintas polaridades una respecto a otra, caracterizada dicho método por el hecho que para la grabación de señales, en todas las pistas la polaridades de las señales en los periodos de linea se cambian por grupos periódicamente recurrentes, con el mismo diseño de distribución de polaridades consecutivas, y de que los grupo comprenden por lo menos cuatro periodos de linea, es decir, un múltiplo entero y también un múltiplo par de los m ismos, para una señal que en el espectro de frecuencia presente máximos separados a distancias equivalentes a la mitad de la frecuencia de lineas, y se corren o desvía uno respecto a la frecuencias presente máximos separados a distancias equivalentes a la mitad de la frecuencia de lineas y se corren o desvían uno respecto a otro en por lo menos un periodo de linea, en pistas adyacente.
