Abstract

Perfeccionamientos en aparatos para convertir información de crominancia codificada SECAM a una señal de crominancia apropiada para alimentación a un descodificador PAL, cuya información de crominancia aparece durante partes de la imagen de intervalos de línea a partes de las mismas, caracterizados porque el aparato comprende: un dispositivo discriminador de frecuencia, que responde a la información de crominancia codificada en forma SECAM, para desarrollar en secuencia, durante parte de imagen de intervalos de líneas sucesivas una primera y una segunda señales de diferencia de color respectivas, una fuente de oscilaciones de una frecuencia que corresponde a la frecuencia de la subportadora de color PAL normal; y medios que responden a la salida del dispositivo discriminador de frecuencias y a la salida de la fuente de oscilaciones, para desarrollar una señal de crominancia de salida.
