Abstract

SE DESCRIBE UN METODO PARA INCREMENTAR LA EFICACIA DE COMPRENSION DE LA TRANSMISION O ALMACENAMIENTO DE SEÑALES DE IMAGENES DE VIDEO. EL DISPOSITIVO PARA LLEVAR A CABO EL METODO DE CODIFICACION INCLUYE UNA UCP (10), UN ROM (20) UN RAM (30) Y UNA SECCION DE ESCANEO POR ZIG-ZAG. LA UTILIZACION DEL METODO IMPLICA PRIMERO LA EJECUCION DE LOS CAMPOS, UN CONTADOR Y UN NUMERO COEFICIENTE SON INICIALIZADOS. A CONTINUACION, EL COEFICIENTE AC SON ZIG-ZAG ESCANEADOS Y LOS COEFICIENTES AC SON COMPROBADOS PARA VER SI SON 0 O NO. SI EL COEFICIENTE AC ES CERO, LOS CAMPOS EJECUTADOS Y EL CONTADOR SON INCREMENTADOS EN 1, Y LOS COEFICIENTES NO CERO SON AGRUPADOS CONJUNTAMENTE. LOS COEFICIENTES NO CERO SON CODIFICADOS Y UN CODIGO EONZ ES INICIADO PARA INDICAR LA FINALIZACION DE LA CODIFICACION DE LOS COEFICIENTES NO CERO. A CONTINUACION, LOS COEFICIENTES EJECUTADOS DE LA TABLA DE CODIFICACION SE HACE MAS PEQUEÑA, LA LONGITUD MEDIA DE LOS CODIGO PALABRAS PUEDEN ACORTARSE Y LA CODIFICACION Y DECODIFICACION SE PUEDE LLEVAR A CABO DE UNA FORMA SIMPLE.
