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.

ISDB-T Remux – Remultiplexes an existing 188- or 204-byte transport stream file into an ISDB-T/Tb
(ARIB STD-B31) compliant file (204 bytes per packet). The created file extension is .RMX and includes
TMCC and IIP sections.

MPEG Player – Plays MPEG-2 streams.

Multiplexer - Getting started

The Multiplexer provides offline 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

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 o f 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.

While examining transport streams, it is possible to copy sections to the main
multiplex using the standard Windows techniques: copy and paste or by dragging
and dropping them with the aid of the mouse.

For example, to import a section that is visible in the Examine TS window intothe
new multiplex configuration:

1. Select the Navigator Tables view.

2. Highlight the section to be copied in the Examine TS windowanddoone

of the following:

Select Edit > Copy. With the Navigator Tables view active, click Edit >

Paste .

Using the mouse, place the cursor over the highlighted section, press and

hold the left button on the mouse and drag the section onto the Navigator
Tables view. Release the mouse button.

3. Note that the copied section is placed in the PSI/SI structure at the correct
location. If any conflict arises concerning similar PID numbers, a new version
is created.
