Abstract

UN SISTEMA DE MEMORIA FIJA DIGITAL (10) RECIBE SEÑAL DE VIDEO 4:2:2: D1 DIGITAL COMPUESTA INTRODUCIDA EN PARALELO (12) O EN SERIE (14). LAS SEÑALES SE FACILITAN EN FORMA COMPONENTE SELECTIVAMENTE A UNA DE LAS MEMORIAS DE CUADRO (18) Y (20). LAS SEÑALES COMPONENTES SE FACILITAN DESDE LAS MEMORIAS DE CUADRO (18) Y (20) A DISCOS DUROS (22) A TRAVES DE UNA MEMORIA INTERMEDIA (24) Y CIRCUITOS (26) DE ENTRADA Y SALIDA (IÑO) DE DISCO. CADA UNO DE LOS DISCOS DUROS (22) ALMACENA IMAGENES DE VIDEO FIJAS COMO MARCOS DIGITALES DE 525 O 625 LINEAS PARA ENTRADAS Y SALIDAS DE SEÑAL COMPUESTA DE NTSC O PAL. CAMPOS Y Y C DE INFORMACION COMPONENTE DE SEÑAL DE VIDEO SE SUMINISTRAN DESDE LOS DISCOS DUROS (22) A TRAVES DE LA MEMORIA INTERMEDIA (24) Y UNA DE LAS MEMORIAS DE MARCO (18) Y (20) A UN COMPONENTE (28) PARA LA SALIDA COMO SEÑALES DE VIDEO 4:2:2 DIGITALES. LA MEMORIA INTERMEDIA (24) OBTIENE LOS CAMPOS DE SEÑAL DE VIDEO TANTO PARA IMAGENES DE TAMAÑO COMPLETO O IMAGENES DE TAMAÑO 1/4, DONDE SE NECESITA UNA RED PARA LA LECTURA Y SELECCION. CUANDO LAS IMAGENES DE TAMAÑO 1/4 SE DESEAN, LAS SEÑALES DE VIDEO DE CAMPO SE OBTIENEN DIRIGIENDO CADA PIXEL CUARTO DEL CAMPO PARA SU LECTURA.
