Abstract

Изобретението се отнася до метод и устройство за гарантиране пълнотата и достоверността на данни, предавани между управляващ център и една или няколко получаващи единици (възли, устройства). Всяка получаваща единица съдържа декодер (IRD), защитен модул (SC) и средство за комуникация (NET, REC) с управляващия център. Методът се изразява в преценяване на контролната информация (Нх), представяща резултата от операцията, предвидена да бъде еднопосочна и безконфликтна, изпълнена върху цялата или част от предадената информация и предаваща резултата до управляващия център за проверка. Центърът може да информира декодера относно достоверността на данните чрез обратните канали или чрез главния каналза връзка.
