Abstract

Perfeccionamientos en aparatos de identificación de conmutación de línea a línea en receptores de televisión de doble norma, del tipo que se disponen en un receptor de televisión en color sujeto a recepción de señales de televisión en color compuestas inclusivas de un canal de crominancia codificadas en formato SECAM; comprendiendo el componente de crominancia codificado en formato SECAM, durante las partes de imagen de intervalos de líneas alternos, una primera frecuencia de la subportadora modulada de acuerdo con una primera señal de diferencia de color, y durante las partes de imagen de los intervalos de línea intermedios, una segunda frecuencia de la subportadora modulada de acuerdo con una segunda señal de diferencia de color, con una impulsión de entrada de oscilaciones a la frecuencia central de la primera subportadora que precede a la parte de imagen de cada uno de dichos intervalos de línea alternos, y con una impulsión de entrada de oscilaciones a la frecuencia central de la segunda subportadora que precede a la parte de imagen de cada uno de los intervalos de línea intermedios.
