Abstract
LOS DATOS CODIFICADOS SE REPRODUCEN DE FORMA INVERSA MEDIANTE LA DESCODIFICACION DE CADA IMAGEN SOLAMENTE UNA VEZ Y UTILIZANDO SOLAMENTE TANTAS SECCIONES DE MEMORIA DE MARCO COMO SEAN NECESARIAS EN UNA OPERACION DE REPRODUCCION NORMAL. UN DETECTOR DE CABECERA DE IMAGEN (34) DETECTA UNA CABECERA DE IMAGEN DE LOS DATOS LEIDOS DE UNA MEMORIA INTERMEDIA DE CODIGO DE VIDEO (10) PARA IDENTIFICAR EL TIPO DE IMAGEN. LA INFORMACION DEL TIPO DE IMAGEN CONTROLA UN CIRCUITO DE SELECCION DE DATOS DE IMAGEN (35) PARA SELECCIONAR LOS MARCOS DE LAS IMAGENES I Y P IGUALES EN NUMERO AL NUMERO DE LAS SECCIONES DE MEMORIA DE MARCOS EN UN BANCO DE MEMORIA DE MARCOS (16). LOS MARCOS SELECCIONADOS SON SUMINISTRADOS A UN CIRCUITO VLC INVERSO (11) PARA SER DESCODIFICADOS, INICIADOS EN LA CABEZA DE UN GOP CON UNA IMAGEN I. LAS IMAGENES I Y P DESCODIFICADAS SE ALMACENAN EN UN MARCO DE MEMORIA DE MARCOS (16) Y SE TRANSMITEN A UNA UNIDAD DE REPRESENTACION (18), COMENZANDO CON LA IMAGEN TEMPORALMENTE MAS RECIENTE Y LEYENDO HACIA ATRAS.
