Abstract
LOS SISTEMAS CONOCIDOS BASADOS EN CODIFICACION Y DESCODIFICACION ESTRATIFICADA NO CONTEMPLAN EL AREA SUPERFICIAL MAYOR DE UNA IMAGEN HDTV, QUE SE TIENE QUE CODIFICAR A ALTA RESOLUCION, COMPARADA CON EL AREA DE SUPERFICIE MENOR DE UNA IMAGEN CONVENCIONAL, QUE SE DERIVA DE LA MISMA, QUE TIENE QUE CODIFICARSE A BAJA RESOLUCION. UNA MEJORA EN LA EFICIENCIA DE LA CODIFICACION Y LA DESCODIFICACION SE CONSIGUE ACTUALMENTE TENIENDO EN CUENTA ESTO CON EL SISTEMA DE ACUERDO CON LA INVENCION Y MANTENIENDO EL ACOPLAMIENTO ENTRE LAS DOS CAPAS EN EL CODIFICADOR Y EL DESCODIFICADOR SI UN ELEMENTO DE LA IMAGEN SE SITUA EN UNA SECCION CORRESPONDIENTE DE DOS IMAGENES E INTERRUMPIENDO EL ACOPLAMIENTO SI UN ELEMENTO DE LA IMAGEN SE SITUA FUERA DE LA SECCION CORRESPONDIENTE DE LAS DOS IMAGENES.
