Application Desktop icon

Multiplexer – Multiplexes table information and packetized elementary streams together to synthesize new transport streams. A ﬁne level of control is provided to allow nonconformances and test cases to be speciﬁed for new transport streams.

TS Editor – Viewing and editing transport stream packets, using a hexadecimal view of the packet contents and semantic interpretation of the header. Provides facilities to remap PIDs, recalculate PCR values and introduce PCR inaccuracies.

Multiplexer

Multiplexer - Getting started

The Tektronix Multiplexer provides off-line multiplexing of ATSC, MPEG-2, DVB, and ISDB transport streams.

Transport streams (TS), Elementary Streams (ES), Packetized Elementary Streams (PES), and Packet Identiﬁers (PID) can be selected, manipulated and recombined

orm customized, synthesized transport streams. Program Speciﬁc Information

Any ﬁle holding to the relevant standards, can be opened. Many nonconformant streams can be opened provided that the PAT, PMT, and MGT tables correctly specify all the other tables and their PIDs.

Multiplexer is used for generating both conformant and n onconformant streams. Having generated a nonconformant stream, it may not be possible to successfully open it again in Multiplexer.

The speciﬁcation for a new transport stream may be saved to a multiplex conﬁguration ﬁle. This also saves time for opening large MPEG ﬁles, since the speciﬁcation contains the results of the analysis from opening the original MPEG ﬁle.

NOTE. The multiplex conﬁguration ﬁle does not contain a copy of the transport

stream; instead it refers to the original MPEG ﬁle by the full path name. Deleting or moving the MPEG ﬁle will result in a dialog box prompting for the new location of the ﬁle.
