Abstract

Método y sistema de generación de un flujo de transporte corregido (2) a partir de un flujo de transporte original (1) que demultiplexa un flujo de datos de señalización que comprende información de señalización (8) en la que se indica si en el flujo de transporte original se multiplexa un flujo de datos de un servicio de accesibilidad (9), verifica si dicha información es correcta, y en caso contrario, genera el flujo de transporte corregido (2) sustituyendo dicha información de señalización (8).
