Alignment of compressed data packets on the nominated respect packets of a transport bit stream, with control of the output bit rate of data compression as a function of the rate of the nominated respect packets

摘要

To enable a single programme in a multiple programme MPEG transport stream (MPTS) to be replaced seamlessly by a locally generated programme, the local coder received the MPTS as a reference signal and outputs transport packets in alignment with the packets of the programme to be replaced. Timing and other packet parameters are also copied.
