Abstract

Устройство для отбора заранее заданных пакетов компонент сигнала из потока пакетов сигнала включает устройство управления, реагирующее на выбор пользователя и на переданный программный указатель, для определения кодов идентификаторов пакетов (ScID), для компонент сигнала соответствующей программы. Идентификаторы соответствующих компонент хранятся в программируемых регистрах. Идентификаторы из соответствующих пакетов потока сигналов последовательно загружаются в дополнительный регистр. Схемы сравнения, связанные с программируемыми регистрами, сравнивают хранимые идентификаторы с идентификаторами пакетов из потока сигналов. Выходные сигналы от соответствующих схем сравнения управляют использованием соответствующих пакетов компонент сигнала из потока сигналов. Программирование идентификаторов в соответствующих программируемых регистрах осуществляется в определенной последовательности для предотвращения случайного принятия системой нежелательных данных.
