Abstract

UN TERMINAL DE ENTRADA VIDEO AUXILIAR (TERMINAL-S 10) ACOPLA LAS SEÑALES DE ENTRADA DE LUMINANCIA Y CROMINANCIA PARA LAS ENTRADAS RESPECTIVAS DE CIRCUITOS DE CORRIENTE DE PICO (52,58) EN EL PROCESADOR DE REPRESENTACION (40) DE UN RECEPTOR. LA SEÑAL DE ENTRADA DE CROMINANCIA (64) ESTA SUJETA A UNA PRE-DISTORSION (DESAPARICION DE CORRIENTES EN PICO (80)) PARA CORREGIR LA DISTORSION DE AMPLITUD DE BANDA LATERAL EN EL FILTRO DE CORRIENTE DE PICO DE CROMINANCIA (58) DEL RECEPTOR IMPIDIENDO DE ESTA FORMA LA DISTORSION DE COLOR EN LAS IMAGENES REPRESENTADAS. LA SEÑAL DE LUMINANCIA (62) ESTA SUJETA A LA CORRIENTE DE PICO ADICIONAL (70) A UNA FRECUENCIA MAYOR QUE LA FRECUENCIA DE CORRIENTE DE PICO CARACTERISTICA DEL FILTRO DE CORRIENTE DE PICO DE LUMINANCIA MEJORANDO DE ESTA FORMA LA NITIDEZ DE LAS SEÑALES DE ENTRADA DE LUMINANCIA DE BANDA ANCHA REPRESENTADAS POR EL RECEPTOR.
