MTG300

The MTG300 MPEG-2 Generator is a flexible,
cost-effective source of MPEG-2 transport
streams for design evaluation and conformance
testing of compressed digital video products.
This instrument offers storage and playback of
MPEG-2 transport streams compliant with the
ATSC,DVB and ISDB standards.The MTG300
generates error-free, seamless transport
streams for long term playout.To facilitate
complete stress testing, the MTG300 features
the most comprehensive capabilities for
customizing transport streams on the market.
The basic functionality of the MTG300,
combined with the customization features
of the MTG300, makes this MPEG generator
ideally suited for use in research, design
and manufacturing applications.

Seamless Looping

Any transport stream can be looped, with real-time
update of all time stamps, continuity counters and
time tables (TDT or STT).

PSI, SI or PSIP
Tables Manipulation

PSI/SI/PSIP tables can be dynamically deleted, inserted
or replaced by user-defined tables.Tables can be
created by the MTS300 Series.The starting and ending
time of the table changes can be set to any value
within PCR reference time.

Real-time Stress Addition

The following can be applied to any transport stream:

TS Header Stress –

The packet headers for any TS element can be
modified to any value.
Packets from any PID can be deleted over a
user-specified interval.
Time tables (TDT or STT) can be inserted,including
real-time updating of the time.
Undefined PIDs (i.e., not default PID numbers,or those
referenced by the PAT or any PMT) can be inserted.

PCR Stress –

PCR Jitter: For a PCR value change,pattern,period,
duration and amplitude can be defined.
PCR Period: For a PCR packet period change,both
period and period jitter are supported; pattern, period,
duration and amplitude can be defined.

Transport Stream Storage

At least 18 GB standard.Any transport stream length,
up to the entire storage amount, can be generated.

Sample Transport
Streams

Sample streams can be seamlessly looped, including
updating of all time stamps, continuity counters and
time tables (TDT or STT), without buffer under- or
overflow.

Transport Stream Creation

Compatible with transport stream recorders, such as
the MTS300 Series, that can export a captured file in
*.trp format.Also compatible with custom transport
streams created by the MTS300, the MTS300 Stream
Application Creation or any other software package that
creates files in *.trp format.

Networking

100Base-T

MTG Comm, an included standard accessory PC
software program, can download and upload
transport streams through the Ethernet port to/from
the MTG300.

Remote Control

MTG Comm, an included standard accessory PC
software program, can control MTG300 through the
Ethernet port. Stream generation start/stop, output
stream selection and the recall of user presets can
be controlled.
