Abstract

UN METODO DE REPRODUCCION ESPECIAL DE DATOS CODIFICADOS LEE Y DESCODIFICA DATOS DE GRUPO DE UNIDAD COMPUESTOS DE DATOS CODIFICADOS EN EL INTERIOR DEL MARCO, DATOS CODIFICADOS PREDICTIVOS HACIA ADELANTE EN EL INTERIOR DEL MARCO Y DATOS CODIFICADOS PREDICTIVOS BIDIRECCIONALMENTE, ESCRIBE LOS DATOS DESCODIFICADOS EN UNA MEMORIA INTERMEDIA DE MARCOS (2-3) Y, DESPUES DE LEER LOS DATOS DESDE LA MISMA, MUESTRA (3) LOS DATOS. EL METODO COMPRENDE LOS PASOS DE DESCODIFICAR DE FORMA CONTINUA PARTES DE LOS DATOS CODIFICADOS EN EL INTERIOR DEL MARCO Y LOS DATOS CODIFICADOS PREDICTIVOS HACIA ADELANTE EN EL INTERIOR DEL MARCO QUE CONSTITUYEN LA LECTURA DE DATOS DEL GRUPO DE UNIDAD, MIENTRAS QUE DESCODIFICA INTERMITENTEMENTE LOS DATOS CODIFICADOS RESTANTES; ESCRIBIR LOS DATOS DESCODIFICADOS EN LA MEMORIA INTERMEDIA DE MARCOS (2-3); LEER LOS DATOS DE LA MISMA EN UN ORDEN INVERSO AL DE LAS IMAGENES ORIGINALES; Y MOSTRAR LAS IMAGENES (3) ASI LEIDAS. UN APARATO DISEÑADO PARA LLEVAR A CABO EL METODO ANTERIORMENTE DESCRITO COMPRENDE UNA MEMORIA INTERMEDIA (2-1) PARA ALMACENAR LOS DATOS DE EN GRUPO; UN DESCODIFICADOR (22) PARA DESCODIFICAR LOS DATOS CODIFICADOS OBTENIDOS A PARTIR DE LA MEMORIA INTERMEDIA; Y UNA MEMORIA INTERMEDIA DE MARCOS (2-3) PARA ALMACENAR LOS DATOS CODIFICADOS RESPECTIVOS DESCODIFICADOS POR EL DESCODIFICADOR. PUEDE CONSEGUIRSE UNA REPRODUCCION INVERSA ESPECIAL DE LOS DATOS CODIFICADOS PARA REALIZAR IMAGENES REPRODUCIDAS, NATURALES SOBRE UN DISPOSITIVO DE PANTALLA (3) SIN LA NECESIDAD DE ELEVAR LA VELOCIDAD DE TRANSFERENCIA DE DATOS CODIFICADOS HACIA EL DESCODIFICADOR (2-2) O DE ELEVAR LA CAPACIDAD DE ALMACENAMIENTO DE LA MEMORIA INTERMEDIA DE MARCOS (2-3).
