Abstract
UN SOPORTE DE ARCHIVOS (36) TIENE GRABADA UNA SEÑAL DE INFORMACION QUE REPRESENTA PALABRAS DE INFORMACION, PALABRAS CLAVE AÑADIDAS DE UN PRIMER TIPO Y DE UN SEGUNDO TIPO. LAS PALABRAS CLAVE AÑADIDAS DEL PRIMER TIPO TIENEN UNA RELACION PREDEFINIDA PRIMARIA CON LOS PALABRAS DE INFORMACION. LAS PALABRAS CLAVE DEL SEGUNDO TIPO TIENEN UNA RELACION SECUNDARIA PREDEFINIDA CON LAS PALABRAS DE INFORMACION Y LAS PALABRAS CLAVE DEL PRIMER TIPO. LAS PALABRAS CLAVE AÑADIDAS DEL PRIMER Y SEGUNDO TIPO HACEN POSIBLE LA CORRECCION DE ERRORES SEGUN UN ALGORITMO DETERMINADO. LA SEÑAL DE INFORMACION SE DIVIDE EN BLOQUES (1) QUE CONTIENEN CADA UNO UNA PORCION DE CONTROL (20) CON INFORMACION DE CONTROL Y UNA PORCION DE INFORMACION (21) CON INFORMACION PROPORCIONADA POR EL USUARIO. LAS PALABRAS DE INFORMACION Y LAS PALABRAS CLAVE AÑADIDAS DEL PRIMER Y SEGUNDO TIPO ESTAN ORDENADOS E INTERRELACIONADOS DE UN MODO EN EL QUE EL ORDEN DE LAS PALABRAS DE INFORMACION, UNA VEZ QUE LA CORRECCION DEL ERROR SE HA PRODUCIDO SIGUIENDO EL CRITERIO DADO, NO SE VEA AFECTADO. ADEMAS LA APLICACION OFRECE UN MECANISMO PARA LEER LA SEÑAL DE INFORMACION REGISTRADA EN EL SOPORTE DE ARCHIVOS (36). EL MECANISMO SE COMPONE DE UN PRIMER Y UN SEGUNDO DISPOSITIVO DE CORRECCION DE ERRORES (45, 47) PARA CORREGIR LOS ERRORES DE LAS PALABRAS DE INFORMACION EN RESPUESTA A LAS PALABRAS CLAVE AÑADIDAS DEL PRIMER Y SEGUNDO TIPO. EL MECANISMO ADEMAS SE COMPONE DE MECANISMOS DE DECODIFICACION (50) PARA SEPARAR LAS PORCIONES DE CONTROL (20) DE LOS BLOQUES (1) EN RESPUESTA A LAS PALABRAS DE INFORMACION PRODUCIDAS POR EL PRIMER DISPOSITIVO DE CORRECCION (45) AL MISMO TIEMPO QUE LOS RESULTADOS GENERADOS POR EL SEGUNDO DISPOSITIVO DE CORRECCION SE DESCARTAN.
