Abstract

A találmány tárgya egyrészt egy dekóder egy továbbított csomagadatáram feldolgozására, ahol a továbbított adatáram a csomag hasznosrészekbe illesztett csomagokra bontott adatokat tartalmaz, másrészthordozható biztonsági modul a javasolt dekóderben való használatra,harmadrészt egy eljárás a csomag hasznos részben megtalálhatócsomagokra bontott adatokat tartalmazó továbbított csomagáramfeldolgozására. A javasolt eljárás, dekóder és hordozható biztonságimodul a digitális jelátviteli rendszerekben, különösen a digitálistelevízió rendszerekben használható előnyösen. A dekóder egyikmegoldás szerint egy hordozható biztonsági modultól egy meghatározottbiztonsági modul rendszer azonosítót fogadó eszközt, továbbá adekódert a kapott azonosító függvényében konfiguráló eszközt, továbbáa meghatározott biztonsági modulrendszerrel társított csomagokrabontott adatok szűrésére, szűrési adatokat a hordozható biztonságimodultól fogadó eszközt, valamint a kapott szűrési adatok függvényébencsomagokra bontott adatokat szűrő eszközt tartalmaz, másik megoldásszerint a csomagokra bontott adatokból egy meghatározott biztonságimodulrendszerrel társított adatokat kiválasztó első szűrőeszközt,valamint az egy hordozható biztonsági modultól kapott szűrési adatokfüggvényében a kiválasztott adatokat tovább szűrő második szűrőeszközzel rendelkezik. A hordozható biztonsági modul egy meghatározottbiztonsági modulrendszer azonosító eltárolására szolgálómemóriaeszközt, valamint az azonosítót a dekóder konfigurálásához adekóderhez továbbító eszközt tartalmaz. Az eljárás során egyikmegoldás szerint a hordozható biztonsági modultól egy meghatározottbiztonsági modulrendszer azonosítóját veszik, a dekódert a vettazonosító függvényében konfigurálják, a hordozható biztonsági modultólveszik a meghatározott biztonsági modul rendszerrel társítottcsomagokra bontott adatok szűréséhez szükséges szűrési adatokat, és acsomagokra bontott adatokat a kapott szűrési adatok függvényébenszűrik, másik megoldás szerint a csomagokra bontott adatokból egymeghatározott biztonsági modulrendszerrel társított adatokatválasztanak ki, és a kiválasztott adatokat egy hordozható biztonságimodultól kapott szűrési adatok függvényében szűrik.
