Abstract

SISTEMAS DE TRANSMISION DE IMAGENES DE TELEVISION, EN LOS QUE, EN UN TRANSMISOR, SE COMPARAN SEN/ALES QUE REPRESENTAN CUADROS SUCESIVOS DE UNA IMAGEN A TRANSMITIR CON REPRESENTACIONES DE CUADROS ANTERIORES DE DICHA IMAGEN, ALMACENADOS PREVIAMENTE EN UNA PRIMERA MEMORIA DE IMAGENES, Y SE GENERAN DATOS RELATIVOS A CAMBIOS EN LOS ELEMENTOS DE LA IMAGEN QUE SON TRANSMITIDOS A UN RECEPTOR DONDE SE MODIFICAN LAS REPRESENTACIONES DE LOS CUADROS ANTERIORES ALMACENADOS ANTERIORMENTE EN UNA SEGUNDA MEMORIA DE IMAGENES, EN RESPUESTA A LOS DATOS TRANSMITIDOS PARA REPRODUCIR LOS CUADROS POSTERIORES DE LA MENCIONADA IMAGEN.CARACTERIZADOS PORQUE LA FRECUENCIA DE LOS CUADROS DE LA IMAGEN A TRANSMITIR ES DIFERENTE DE LA FRECUENCIA DE CUADROS CON QUE SE PRODUCEN LOS CUADROS POSTERIORES EN EL RECEPTOR; Y PORQUE LA FRECUENCIA DE CUADROS CON QUE SE TRANSMITEN DICHOS DATOS ES MENOR QUE LA MENOR DE LAS DOS FRECUENCIAS O IGUAL A ELLA.
