New Applications and New Features
This section describes new applications and features that have been added to
existing applications for the MTS 200 Series. For more information about these
changes, refer to the user manual that shipped with your product.
Dolby Digital Audio
Stream Analyzer
ATSC Table Editor
This new application provides the ability to analyze AC-3 audio streams that
have been stored on the MTS system hard drive. The analysis is based on the
same paradigm as used in the MPEG-2 Audio Analyzer (AUSTRAL), which is
currently available from Tektronix. Structural, interpretive, and graphical views
are available. These include a Dialog Normalization Graph, a Heavy Compression Graph, and a Dynamic Range Control Graph. You can select which
portion of the stream you wish to analyze.
This new application provides both a table editor for creating or altering
ATSC-specific tables and an analyzer function, which checks edited tables for
compliance with the ATSC standard. You have access to two types of hierarchical representations of the table/stream data: one specific to the tables themselves
and one showing the relationships between all the tables and the programs that
contain them.

Open Mux Server
MTS2AN
MTS2CR
This new application allows you to take MPEG-2, DVB, or ATSC-compliant
transport streams and remultiplex them into a single compliant transport stream.
It also provides the ability to take video and audio elementary streams as input
and multiplex them into multiple-program transport streams. Remultiplexing is
accomplished by a client operation.
Open Mux supports the ability to provide seamless looping of specially
constructed streams.
Version 3.0 of the software adds the following new features to the Transport
Stream Analyzer:
H ATSC/PSIP Analysis
H Mega-frame Table Analysis
Version 3.0 of the software adds the following new features to the Transport
Stream Creation (Multiplexing):
H ATSC Deferred-Time Multiplexer
H Capability to apply Mega-frame information to output
MTS2TS
MPEG-2 DVB/ATSC
System Analyzer
Version 3.0 of the software adds the following new features to the Transport
Stream Analysis/Creation:
H ATSC/PSIP Analysis
H ATSC Deferred-Time Multiplexer
H Mega-frame Table Analysis
Version 3.0 of the software adds the following new features to the MPEG-2
System Analyzer:
H Mega-frame Table Analysis. You can analyze the tables associated with
Mega-frame for correctness of content.
H ATSC/PSIP Analysis. You can specify ATSC/PSIP analysis by selecting
ATSC/PSIP in the Options menu of the DTA. When you select this option,
the following information and displays are available:
H Hierarchical view of the selected ATSC transport stream complete with
new icons for the ATSC-specific tables.
H Interpreted views of the information within each of the ATSC tables in
the selected transport stream.

H Analysis of the selected stream for consistency with the ATSC specifica-
tion, including table repetition rates, semantic analysis, and syntactic
analysis.
H Buffer information for the video, audio, and system elements of the
selected ATSC transport stream.
Multiplexer
Real-Time Analyzer
With version 3.0 software, you can use the Deferred-Time Multiplexer to
multiplex ATSC-compatible transport streams.
Version 3.0 of the software adds the following new features to the Real-Time
Analyzer:
H Open Table Private Syntax Generator/Interpreter. This application allows you
to create a private table syntax. This syntax can be linked to the Real-Time
Analyzer so that streams containing tables of this type can be fully analyzed.
H ATSC/PSIP Analyzer capability. You can now use the RTA to display a
hierarchical view of the transport stream contents using the same paradigm
as used for the DVB and MPEG-2 stream analysis. You can analyze the six
table types specified by ATSC. Semantic and syntactic analyses are
performed in accordance with the ATSC standards documents.
H SNMP Agent. An MIB interface has been added. The MIB provides
information on analysis data collected by the RTA. Trap functions have also
been added, to provide you with immediate notification of errors or
predetermined conditions during analysis. At this release, the MIB does not
provide access to ATSC analysis information or SI-DAT information.
H IP Data Monitoring. This feature allows you to analyze DSM-CC compliant
protocols described in the DVB standard. You can:
H Display transport streams containing IP datagrams in the tree view
H View the SI-DAT tables in detail
H Analyze the SI-DAT tables for proper syntax
H Monitor data flow on TCP/IP data broadcasting sessions.
H Screen Resolution Control. Pie charts, bar graphs, and various control or
error indicators can be properly displayed on screens which have resolution
down to 800 x 600 pixels.
H Ghost PID Analysis. The RTA can identify ghost PID types. Analysis is
available for each ghost PID whose type can be identified.

H Mega-frame table analysis. You can analyze the tables associated with
Mega-frames for correctness of content.
H Event Reporting. A hierarchical view has been added to the events reporting
panels. This view is a structured index to the error reporting groups, which
are defined as Multiplex, Syntax, Clock, and Rate. A high-level display of
errors is provided for each group, to include a summary list of the errors and
an error-occurrence histogram. You can display lower-level information by
double-clicking on the error category in the hierarchical view.
H Timing Graph Improvements. Histogram displays plot frequency deviation
or timing intervals on the X-axis and frequency-of-occurrence information
on the Y-axis.
H Events Viewer. The identifier code word has been extended from 16 bits to
32 bits for individual events. In this way, the events number duplication can
be eliminated.
H Version Information Display. The About Box now contains more information
about SW and HW versions.
H Settings Dialog Box. The tabs at the top of the panels are replaced by a
narrow hierarchical view panel at the left of the display, which lists each
panel title. Click the icon for a panel to access the panel.
H PID Allocation View. You can define the PID selection by dragging and
dropping an icon from the hierarchical display to the Selection button. You
can also display the Average Rate or Current Rate by clicking the toggle
button near the top of the view window.
H PID List View. The location of the pie chart and the PID list has been
inverted from its alignment in version 2.5.
H Program Allocation View. A horizontal bar graph display of the current
bitrate usage for each program has been added, so that you can select specific
programs for viewing. The display also includes an indicator of the peak
bitrate detected during a measurement session.
H MPEG-2 Enhancements. A Transport Stream Description Table (TSDT) icon
is added to the RTA hierarchical view when this table type is detected.
H Enhanced ETR 290 measurement capability. The ETR 290 measurement
suite has been updated to reflect the latest specified measurements. However,
the T-STD buffer analysis is not included with this release.

This section describes problems you might encounter while using version 3.0
and describes how to minimize or eliminate the impact on product operation.
MTS2AC3
MTS2ES
ATSC T able Editor
Data Store Administrator
The MTS2AC3 is a stand-alone software product intended for installation on
personal computers running Windows NT 4.0. You cannot install MTS2AC3 on
a Tektronix MTS100 or MTS200-series test system. To install the Dolby Digital
Audio Stream Analyzer on your personal computer, order MTSFAC3; please
contact your Tektronix representative for additional information.
The MTS2ES is a stand-alone software product intended for installation on
personal computers running Windows NT 4.0. You cannot install MTS2ES on a
Tektronix MTS100 or MTS200-series test system. To install the elementary
stream analyzers on your personal computer, order MTS2F07; please contact
your Tektronix representative for additional information.
Reference IRSdb05538: ETT Saving & Loading. When you save a new EIT file
using the PSIP Table Editor, the following error message may appear when you
try to reopen the saved file: “The file name is not correct.” To avoid this error,
use the file naming convention: namexxx.ett, where xxx is a number between 0
and 127. For example, toto001.eit.
Reference N/A. Stream length limitations can be encountered when you attempt
to generate streams saved on the Loop Partition of the Data Store.
To avoid generating incomplete streams, copy the stream from the Loop Partition
to the test system hard drive with the Data Store Administrator. Then copy the
stream from the system hard disk to the Single Shot Partition. This will ensure
that a complete stream is generated from the Single Shot Partition.
Reference CSEbd12699. All four Data Store disks must read/write at the rate
required for acquisition and generation. As a disk ages, its performance can
degrade until it cannot always read/write quickly enough for the highest Data
Store acquisition and generation rates—even though it continues to meet the disk
manufacturer’s specification for average access speed. One degraded disk can
prevent acquisition or generation at high data rates; in these circumstances, a
“Disk n too slow” (where n is the number of the inadequate disk) error message
appears.
Replace the slow disk to restore the Data Store system’s ability to acquire and
generate at the desired data rate.

MPEG-2 DVB/ATSC
System Analyzer
Reference N/A. While analyzing large transport stream files, the analyzer can
appear to be busy with no indication of progress; in addition, the message
window can obscure the “Press Escape to abort” reminder. Analysis of large
transport stream files can take many minutes; press
MPEG-2 System Analyzer operations.
Reference CSEdb03373. When displaying a large font, some characters are
displayed badly (or not at all) in the packet views. Use a smaller font.
Reference CSEdb08680. Violations of the repetition time limits for PAT, CAT, and
PMT (as defined by the DVB guidelines) are not reported. The limit used is 100
ms instead of the correct 40 ms.
Reference CSEdb17277. Streams generated with the MPEG Test System
Multiplexer application can cause buffer overflow during Dynamic Analysis with
the MPEG-2 System Analyzer. This can occur because the Dynamic Analysis
algorithm uses the “Leak method” to transfer video elementary stream data from
the main buffer (MBn) to the elementary stream buffer (EBn); therefor, buffer
overflow can occur when analyzing streams—such as those created with the
Multiplexer application—that require “VBV delay method” data transfer.
Refer to ISO/IEC 13818-1 for additional information about leak method and
VBV delay method buffering.

Open Mux Server
Real-Time Analyzer
Reference IRSdb05528: PMT video description. In ATSC mode, when the
configuration is one PSI/ATSC input and one ES video only input, the video
descriptor and smoothing descriptor may be missing.
Reference N/A. When using the System Analyzer to examine a partial, filtered,
transport stream captured with the RTA, timing analysis is not advised for the
following reasons:
H The System Analyzer cannot compute the bit rate if the first PMT declared
in the PAT has no PCR information, which occurs when the corresponding
PID has been filtered by the Real-Time Analyzer.
H Even if you input the correct overall bit rate, all information related to timing
(PCR, PTS/DTS, section rates, and dynamic analyses) can be incorrect
because the time distribution of the packets repartition is lost when filtered
data is captured. PCRs, for example, will be incorrect because they are
computed at the source on the complete stream, not on a filtered part of it.
If you intend to perform in-depth timing analysis of a captured stream, always
select No filtering mechanism on the Data Storage Configuration tab of the
RTA Settings window.

Reference CSEdb19930. To save, load (restore), or delete Real-Time Analyzer
configuration profiles, you must be logged in to Windows NT as a user that is a
member of either the Administrators user group or the Backup Operators user
group. To restore or delete a profile, you must be logged in as the user who saved
the profile.
The default user in the standard MTS200 series V2.5 configuration, MTS100, is
a member of the Backup Operators group. To add a user or change the group
memberships of a user, log in as the administrator and select the User Manager
application from the Windows NT Start/Programs/Administrative Tools
(common) subdirectory. Refer to the Windows NT documentation for additional
information about the User Manager application.
Reference CSEdb20616. Files acquired through RTA data storage are always
truncated to a multiple of 24064*N bytes, where N is the number of data store
disks. In a standard MTS200 Series test system, therefore, the saved file size
must be an exact multiple of 96256 bytes, and the resulting file can be up to
96255 bytes smaller than the total size specified in the Before Event and After
Event settings fields.
Reference IRSdb05371: Unable to start analysis after Data Storage start/stop
warning. Under certain conditions (if the Data Store Administrator is already
running and you start the real-time analyzer), selecting Configuration/Settings/
Data Storage may prevent you from starting analysis. Click Cancel to exit the
Data Storage Window, and then start analysis.
Reference IRSdb05445: Semantic errors not shown in View Section analysis.
For some streams, the Section Analysis view shows only syntactic errors, and
not semantic errors.
Reference IRSdb05587: EMM syntax error reported as ECM syntax error. In some
cases, the EMM table might have the table id of an ECM, which creates an error
message.
Reference IRSdb06399: Maximum rate for a single PID seems limited to 30 Mb/s or
48 Mb/s. 48 Mb/s is the maximum rate of a single PID that can be analyzed by
the real-time analyzer.
