Abstract

Устройство и способ, обеспечивающие форматирование исполняемых кодов и данных, определяющих интерактивные прикладные программы, с видео- и аудиопрограммным материалом с целью обеспечения надежного и удобного доступа включает в себя сжатие аудио- и видеопрограмм. Сжатые аудио- и видеопрограммы (A/V-программы) сегментируют на транспортные пакеты и идентифицируют первым и вторым служебными идентифицаторами SCID и SCID . Интерактивные прикладные программы, ассоциированные с аудио- и видеопрограммами, компилируют в функциональные модули и уплотняют. Образуют другие модули, называемые "сигнальными модулями", для инициирования в соответствующих приемниках способности приостанавливать или возобновлять исполнение интерактивной прикладной программы. Сигнальные модули мультиплексируют в пакетный поток, чем обеспечивается возможность надлежащего возобновления программы соответствующими приемниками при проявлении таких изменений в получаемых сигнальных компонентах. Модуль может представлять собой исполняемое программное обеспечение или данные. Модуль включает в себя код/данные и заголовок. Кодовая/информационная часть каждого модуля сопровождается битами контроля циклическим избыточным кодом (CRC), присоединяемыми к модулю. Соответствующие модули сегментируются на транспортные пакеты. Транспортные пакеты формируют в передаваемые блоки, содержащие целое число кодовых / информационных транспортных пакетов и заглавный транспортный пакет. Видеопакеты, аудиопакеты и модульные пакеты подвергают затем временному последовательному мультиплексированию с целью передачи.
