MTS300

Real-time Monitoring

The MTS300 uses intuitive icons and colors

to indicate the current status of MTS300

I/O ports and any MPEG transport stream

under analysis. A simple, easy-to-use

display indicates:

The current usage and status of the MTS300
I/O ports. You can install up to four I/O ports
on an MTS300

The current status of monitored transport
streams and the programs within monitored
transport streams. Highly visible indicators let
you quickly identify the transport stream or
program with problems

The type of problem detected in a monitored
transport stream. Intuitive icons show problems
in transport stream protocol, timing errors,
or problems in the video or audio elementary
streams

Using this display, you can easily configure

and control the product in real-time testing

applications, to quickly identify and diagnose

problems with designs or to characterize

design or system performance.

Real-time Analysis

In addition to being an MPEG-2 protocol moni-

tor, the MTS300 gives you powerful real-time

analysis capability to help diagnose difficult

real-time performance problems. The MTS300

real-time analysis capabilities include:

The evaluations recommended by DVB
standard TR 101 290 to verify decodability,
quality and reliability

Tektronix-exclusive timing analysis, including
PCR overall jitter and wander measurements

Flexible, intuitive displays of data rates and
program allocations

Analysis of Mega-frame Initialization packets
used in DVB-T Single Frequency Network
applications

Real-time analysis of transport streams used
in data broadcasting applications based on
ISO/IEC 13818-6 (DSM-CC) and EN 301 192
standards

Fully selectable monitoring depth, fault criteria,
and error reporting and alarms

Triggered capture of transport streams for later
in-depth analysis

Status and error logging

Deferred-time Analysis
and Custom Transport
Stream Creation

A collection of optional MTS300 software

gives you powerful tools for analyzing MPEG-2

transport streams in detail and for creating

your own custom streams to use in functional

and stress testing.

Option DT –

Deferred-time analysis and stream

creation: software tools for detailed syntactic
and semantic analysis of the transport stream,
including T-STD buffer simulation, and for
creating custom streams, including error and
jitter injection utilities

Option ES –

MPEG video and audio elementary

stream analysis: Software tools for detailed
analysis of MPEG video elementary streams,
including GOP (Group of Picture) structure and
I-frame decoding, and for detailed analysis of
MPEG audio elementary streams, including
extraction of audio content into .WAV files

Option AC3 –

Dolby Digital AC-3 analysis:

Software for detailed analysis of Dolby Digital
AC-3 audio content

Option TM –

Transmission Multiplexing

Configuration Control (TMCC) Combiner:
Software for adding TMCC information
into transport streams

New Advanced Multiplexer
and DVB/ATSC Table Editor –
Multiplexer (Option MTS3FMX)

The software can re-multiplex:

MPEG-2 Video elementary streams

MPEG-2 Audio elementary streams

AC-3 Audio elementary streams

MPEG-2 Video PES (packetized
elementary streams)

MPEG-2 Audio PES

AC-3 Audio PES

PIDs from other transport streams

Other data – the bit rate must be specified

The Solution

The multiplexer allows the user to collect

together components from streams recorded

off hard disk or CD/DVD-ROM, manipulate

them in an unlimited manner and then rebuild

a fully compliant output stream for whatever

use is desired. Along the way, the system’s

in-built syntax knowledge of tables and

descriptors ensure compliance and high

quality output of the final multiplex transport

stream.

Decompose Existing Streams

MTS300’s off-line multiplexer accepts any

recorded transport stream as an input source.

The user can then decompose this transport

stream into its component PES. The user can

then save resulting PES and ES streams

onto disk.
