    Abstract: A system and method for multiplexing and remultiplexing whereby multiplexed programs from an input stream are only demultiplexed if they are to be copied or modified locally. Any multiplexed programs which are part of an input stream and which are intended to be part of the output stream are not demultiplexed but are simply passed along to be added to the transport stream with other multiplexed programs. A further inventive aspect comprises a multiplexer apparatus and process whereby dynamic bit rate adjustment is applied to eliminate the need to recalculate timebase information for altered streams.

    Abstract translation: 一种用于多路复用和再多路复用的系统和方法，由此如果要在本地复制或修改来自输入流的多路复用程序，则它们将被解复用。 作为输入流的一部分并且旨在成为输出流的一部分的任何多路复用程序不被解复用，而是被简单地传递，以便与其他多路复用程序相加以传输流。 另一发明方面包括多路复用器装置和处理，由此应用动态比特率调整以消除对重新计算改变流的时基信息的需要。

    Abstract: In order to avoid Packet Identifier (PID) conflicts in multiplexed MPEG-2 program streams, the PID's are re-mapped, in real-time, with unique values, by use of look-up tables. In operation, each program stream transport packet contains a PID value and each program stream has an associated stream identifier (eg queue ID, QID). The PID 11 is used to index a first table 10 for generating an offset value 13. The offset value is then used to address a region 22 of a second table which contains a plurality of new PID values capable of being mapped to the original PID value. The stream identifier (QID) is used to index this region to provide the new PID value 25 which is subsequently exchanged for the original PID.
