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

to f (PSI), Service Information (SI), and Program and System Information Protocol (PSIP) are often referred to as simply SI in this section.

The functions provided include:

zards for common tasks, such as populating streams with Program Speciﬁc

Wi Information/Service Information/Program and System Information Protocol (PSI/SI/PSIP), and programs.

On opening, streams are analyzed and displayed according to the selected standard: MPEG, DVB, ATSC, or ISDB. Scripts are used by the analysis process; this allows private PSI/SI tables and descriptors to be deﬁned.

NOTE. Most examples given in this section of the manual are based on DVB SI.

However, when multiplexing streams containing DSM-CC or MPE addressable sections, the related scripts must not be active.

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 nonconformant 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 n ew location of the ﬁle.

The introduction of the Navigator Programs view has provided a more program-centered means of manipulating SI/PSI. Whole programs can be added to the multiplex and the application will update the associated tables, including the PAT and PMT.

Note that the nodes of the tree structure in the Navigator Programs view are context sensitive. When dragging and dropping ﬁles from either the Examine TS window or from another instance of Multiplexer, a node will be highlighted as the cursor passes over it only when the operation p roposed is valid. Note that there may be a short delay before the node is highlighted while the legality of the operation is checked.
