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

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:

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.

then initiates a playout by loading this file into the player. To play the stream in

The generated transport stream will contain DTS and PTS values calculated
at a constant frame and bit rate. A default frame rate of 25 fps will be used,
unless otherwise specified by the user or derived from the optional VUI

You can specify the constant bit rate or it may be detected automatically by

H.265/HEVC support

The Multiplexer will open and remultiplex CBR Transport Stream files that
include H.265/HEVC video elements. The streams received and generated by the
Multiplexer should comply with the following standards:

H.265/HEVC: ITU-T H.265, Series H: Audiovisual and Multimedia Systems,

Be aware of the following:

The Examine TS window allows you to copy H.265/HEVC elements or
programs from another CBR transport stream file into a new Multiplexer file
(See page 61, Examine Transport Stream window.)

The Multiplexer will not import H.265/HEVC elements directly from disk
