Abstract

Группа изобретений относится к технологиям для спутникового цифрового вещания, в частности для предоставления медиаконтента конечному пользователю без канала обратной связи пользователя. Изобретение включает формирование на сервере электронной программы телевизионных передач передающей стороны файла метаданных сервиса, содержащего предустановленный набор информационных параметров, включающих по меньшей мере версию файла метаданных сервиса, и передачу упомянутого файла метаданных сервиса на вход мультиплексора. Посредством мультиплексора формируют транспортный поток без канала обратной связи пользователя путем встраивания в транспортный поток медиаконтента, поступающего на вход от оператора вещания, метаданных телевизионных передач, файла метаданных сервиса и дополнительную служебную информацию, являющуюся Linkage дескриптором. Передают сформированный транспортный поток на вход клиентского устройства, снабженного тюнером, и осуществляют поэтапно обнаружение файла метаданных сервиса в транспортном потоке посредством Linkage дескриптора, сохранение медиаконтента сервиса на накопитель клиентского устройства на основании сохраненных метаданных сервиса и его шифрование посредством персонализированного аппаратного ключа конкретного клиентского устройства, с возможностью отображения посредством модуля пользовательского интерфейса конечному пользователю в соответствующих категориях списка сохраненного медиаконтента с последующей возможностью его дешифрования и просмотра.
