Abstract

Se describe un método para controlar la decodificación de una pluralidad de corrientes de transporte de programas recibidas por un sistema receptor que comprende recibir una secuencia de mensajes en un sistema secundario de acceso condicional, comprendido en el sistema receptor, cada mensaje se asocia con una de varias corrientes de transporte de programas codificadas y representa una solicitud para regresar información que permite que la corriente de transporte codificada asociada sea descodificada por al menos un módulo descodificador en el sistema receptor, determinar si los mensajes recibidos dentro de cierto intervalo se asocian con una cantidad de corrientes de transporte de programas codificadas diferentes y negar por lo menos una de las solicitudes representadas por los mensajes recibidos en cierto intervalo si el número de corrientes de transporte de programas codificadas diferentes con las cuales se asocian los mensajes excede un número determinado de antemano.
