MTS300 Series Program Stream Analyzer

Preface

This manual describes how to use the Tektronix MPEG Program Stream
Analyzer application. Using the MPEG Program Stream Analyzer, you can view
the fields and values of MPEG2 program streams and MPEG1 system streams at
the pack and PES packet level, extract and save all or part of program and
system streams, and analyze streams for coherence to the MPEG standards.

The MPEG Program Stream Analyzer is part of the MTS300 suite of hardware
and software components used to create, generate, acquire, and analyze MPEG
and DVB transport and program streams and can be used by itself or as an
integral part of the MPEG test system. If you have the Elementary Stream
Analyzers installed on your system, you can send video or audio elementary
streams directly to the appropriate analyzer for analysis at the elementary stream
level.

For information about other MTS300 test system applications, refer to the user
manuals provided with test system or software option. For information about
MTS300 test system hardware installation, specifications, and first-time
operation, refer to the MTS 300 PEG Test System Hardware and Software
Installation Technical Reference, Tektronix part number 071-0667-XX.

For information about the Windows NT Workstation operating system, refer to
the Microsoft documentation that accompanied your test system.

Table i lists the MTS300 MPEG Test System application version supported by
this manual. To verify an application version number, select Help in the
application menu bar; then select About from the Help menu.

Product Description

The MPEG Program Stream Analyzer is used to view and analyze MPEG1 and
MPEG2 program stream structures, fields, and values. This section lists the
various views and analysis functions enabled by the MPEG Program Stream
Analyzer and describes how to find the information you need to install and use
your analyzer the first time.

You can display graphical representations of the MPEG structures of a program
stream using interactive view windows, called interpreted views. Interpreted
views are used to display the following MPEG program stream structures:

H Pack header
H PES packets
H Program stream map (PSM)
H Program stream directory (PSD)

In addition to the interpreted views, the analyzer provides other ways of viewing
MPEG structures and values:

H Hierarchic view
H Hexadecimal and binary views
H System clock reference (SCR) views
H Presentation time stamp/Decoding time stamp (PTS/DTS) views

You can analyze syntactic, semantic, and temporal (time-based) characteristics
of a program stream using the analysis functions provided by the analyzer. The
analysis functions provided are indicated in the following list:

H Multiplex rate analysis
H Syntactic analysis
H Consistency analysis (coherence between all components of the stream)
H System clock reference (SCR) analysis
H Presentation/Decoding time stamp (PTS/DTS) analysis

Getting Started

First Time Operation

Using the MPEG Program Stream Analyzer you can also extract individual
elementary streams for analysis later. Alternatively if you have the Tektronix
MPEG Audio Stream Analyzer and/or MPEG Video Stream Analyzer installed
on your system, you can extract an elementary stream and display a graphical
representation of it using one of the elementary stream analyzers automatically.

The MPEG Program Stream Analyzer is part of a suite of hardware and software
components used to create, generate, acquire, and analyze MPEG and DVB
transport and program streams. Before you can use the analyzer, you need to
ensure that you have entered the correct password for your software configura­tion. To enable the software you have purchased, use the procedure for entering
the general password described in the MTS300 Series Software Only Installation
Instructions, Tektronix part number 075-0630-XX.

Operating Basics

Operating Basics

This chapter provides a functional overview of the MPEG Program Stream
Analyzer interface elements and provides basic operating procedures that will
help you become familiar with the application. This chapter is organized into the
following sections:

NOTE. For basic Windows operating techniques such as minimizing windows or
using the scroll bars, refer to your Windows documentation.

H Functional Overview shows you how to start the MPEG Program Stream

Analyzer and describes user interface elements and characteristics of the
windows used by the analyzer.

H MPEG Program Stream Analyzer Views describes the Hierarchic view and

the common characteristics of Interpreted views.

H Basic Operations describes how to open, extract, and save program or

system stream files; how to print data encoded in the active file; and how to
exit the application.

H Menu Selections provides a table that summarizes the menu selections.

Operating Basics

Functional Overview

Double click the MPEG Program Stream Analyzer icon in the MPEG Test
System program group window.

The MPEG Program Stream Analyzer uses two types of windows to display the
elements of a program stream: the application window and view windows. This
section describes these window types. (See your Windows documentation for
information about common Windows display elements.)

Operating Basics

Menu bar. The menu bar provides access to the commands you use to control the
display, analysis, and look of the MPEG Program Stream Analyzer. A list of
menu selections is provided in Menu Selections beginning on page 2–18.
Complete descriptions of each menu selection are provided in the Options Menu
Reference section beginning on page 3–19.

Upper toolbar. The Upper toolbar provides shortcut buttons to five commonly
used menu selections. These buttons, and the menu selection they represent, are
described in Table 2–1.

Edit toolbar. Selecting an Edit toolbar command button is identical to selecting
the Edit menu selection of the same name. These buttons, described in
Table 2–2, allow you to move through the items of the displayed element and to
view errors in the program stream file.

Operating Basics

NOTE. Items are instances of specific data types, or elements. The first instance
of the program_stream_map() element in the bitstream is the first item displayed
in the PSM interpreted view.

Status bar. The Status bar, located just below the Edit toolbar, provides you with
first level help on using the menus. As you highlight a menu item, the status bar
briefly describes the selection.

View Windows

View windows are used to display program stream files at different levels. Most
of the important information displayed in view windows is discussed in the
discussions of the individual view windows elsewhere in this manual. However,
in addition to standard window controls, the title bar and top line of most view
windows have the following information types in common:

View type Item number PositionFile name

H File name. Indicates the file name of the view displayed.
H View type. The view type indicates the program stream element displayed.

For instance, pack_header() and PES_packet() data represent Pack header
and PES packet elements respectively

H Item number. Indicates the item number of the element displayed. If you

have previously selected the last item, or have selected the Number of Items
command button, the item number is followed by the total number of items
for the displayed element in the bitstream.

2–4

H Position. Indicates the position (in bytes) of the first bit of information

displayed in the interpreted view relative to the first bit of the program
stream. The first bit of the program stream is zero.
