Abstract

El registro de produccion de una señal de television con un dispositivo de desplazamiento de corriente directa evita la distorsion de compresion de una señal de television PAL más. La señal de television PAL más incluye una señal de resolucion vertical para mejorar la resolucion vertical cuya señal de resolucion vertical queda incluida en los mismos bloques de compresion que algunas de las señales de video componentes. Estos bloques de compresion se desplazan hacia un valor establecido de corriente directa de manera que las señales dentro de aquellos bloques de compresion no tengan desplazamientos de corriente directa variables que de otra manera podría resultar la dispersion de compresion. De manera semejante, durante la reproduccion, el valor establecido de la corriente directa se remueve después de la descompresion, y la señal de television original se restablece con una resolucion vertical completa.
