Abstract

Se divulga un aparato para el procesamiento de flujos. El aparato incluye una unidad codificadora de entramado la cual cambia una parte de los flujos con paridades, una unidad de re-codificación por RS la cual corrige por lo menos una parte de la paridad y una parte de datos de los flujos, y genera nuevas palabras de código que corresponden con la parte cambiada de los flujos, y un multiplexor el cual re-construye los flujos con las palabras de código generadas. Esto mejora la calidad de recepción de un receptor de emisión.
