PACKET INSERTION MECHANISM FOR AN IMPROVED ATSC DTV SYSTEM

摘要

Time packet insertion mechanism of the front end of a synchronous digital television transmission system has a spare for niseueul more robust multiplexes packets that are sent with the standard payload packet. The multiplexer also enter the position holding the packet in order to accommodate the content of a cloned robust packet. Multiplexing the robust position and holding the packet is configured to multiplex packets and interleaved with alternating standard. Distribution of packets in the robust frame is determined by the number of robust packet.
