Abstract

UN PROCEDIMIENTO PARA GRABAR Y LEER UNA SEÑAL DE AUDIO Y/O VIDEO (Y APARATO ASOCIADO DE GRABACION Y LECTURA), CONSISTE EN: A) CONVERTIR UNA SEÑAL DE AUDIO Y/O VIDEO EN UNA PRIMERA SERIE DE MUESTRAS, OBTENIDAS POR MUESTREO A UNA FRECUENCIA PREDETERMINADA, Y ESCRIBIR EN UNA MEMORIA DE LECTURA/ESCRITURA (46), B) FORMAR, MEDIANTE LA ULTIMA LECTURA DE LAS MUESTRAS DE LA MEMORIA A UNA FRECUENCIA QUE ES DIFERENTE A LA DE ESCRITURA, Y QUE POSIBLEMENTE ES VARIABLE, UNA GRABACION EN UNA CINTA MAGNETICA (43), ASOCIADA CON UNA SUCESION DE MARCAS TEMPORALES (34) QUE IDENTIFICAN BLOQUES DE GRABACION, Y UN TIEMPO PREDETERMINADO T PARA LEER DE CADA BLOQUE, C) OBTENER, MEDIANTE LA LECTURA DE LA GRABACION Y DE LA SUCESION ASOCIADA DE LAS MARCAS TEMPORALES, UNA SEGUNDA SERIE DE MUESTRAS QUE SE ESCRIBEN EN ORDEN EN LA MEMORIA, Y UNA SEÑAL TEMPORAL, D) APLICAR LA SEGUNDA SERIE DE MUESTRAS LEIDAS DE LA MEMORIA, EN UN ORDEN CORRELACIONADO CON EL DE LA ESCRITURA, A TRAVES DE UN FILTRO HASTA UN TRANSDUCTOR, LA FRECUENCIA DE MUESTREO DE LA GRABACION O LECTURA DE LAS MUESTRAS DE LA MEMORIA, QUE VARIA A LO LARGO DEL TIEMPO, SIENDO DETERMINADAS MEDIANTE LA SEÑAL TEMPORAL, DE TAL FORMA QUE CADA BLOQUE DE GRABACION SE LEA EN EL TIEMPO T.
