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.

ou can initiate a playout in the Multiplexer application using the playout feature

Y as soon as the multiplex operation is complete. Multiplexer creates a temporary transport stream in the location speciﬁed by the Playout Settings and then initiates a playout by loading this ﬁle into the player. To play the stream in the loop mode, enable the loop mode in the Playout settings.

SI scripts are necessary to enable SI table and descriptor data to be analyzed successfully. Scripts are used to enable analysis of SI data dictated by the various international standards, for example, MPEG-2, DVB, ATSC, and ISDB.

Essential scripts are installed and enabled using the Stream Interpretation dialog box. In the absence of any enabled scripts, only the PAT table will be analyzed; all other data will be presented as private data.

Scripts can be loaded from any directory.

Delete the highlighted script.

Change scripts default directory: by default, all scripts are found in a default directory created during installation (tektronix\scripts). This button can be used to set a different default directory.

Note that all scripts supplied by Tektronix in the default installation are installed in a single directory; as long as this directory is designated as the default directory, they will work satisfactorily.

View highlighted script with the associated application; by default, script ﬁles are associated with the ScriptPad utility.
