Abstract

Un circuito de conversión de norma de líneas para convertir una señal de televisión de líneas entrelazadas a ser convertida, que tiene un número dado de líneas por imagen, en una señal de televisión convertida que tiene sustancialmente el doble de número de líneas por imagen mientras conserva la frecuencia del campo, que comprende un convertidor y un interpolador, caracterizado porque el interpolador comprende un circuito de interpolación de campo para obtener cantidades de información prácticamente iguales de cada uno de los campos sucesivos de la señal de televisión a convertir en las líneas de la señal de televisión convertida.
