New Applications and Features
This section describes the new application and features that were added for the
version 6.1 release of the MTS300 MPEG Test System.
One major improvement with this version 6.1 release of the MTS300 MPEG
Test System is support for ISDB-S/ARIB transport streams in addition to
existing support for MPEG-2, DVB, and ATSC standards. ARIB stands for the
Association of Radio Industries and Business. The ISDB-S/AR IB standard
defines elements (carried in table structures) for managing ARIB-compliant
transport streams. These are the ARIB structures analyzed by the MTS300
system:
H Broadcaster Information Table (BIT)
H Download Control Table (DCT)
H Download Table (DLT)
H Software Download Trigger Table (SDTT)
ISDB-S/ARIB transport streams are MPEG-2 compliant streams that conform to
the ITU-R standard for ISDB-S (Integrated Service Digital Broadcasting,
Satellite) multiplexing. An ISDB stream uses TMCC (Transmission and
Multiplexing Configuration Control) data multiplexed in the first eight bytes of
the 16 Reed-Solomon bytes of 204 byte MPEG-2 transport streams. TMCC
information is used to manage the modulation parameters of the transponders in
digital broadcast environments that include multiple broadcasters and types of
services with different transmission requirements.
MTS300 version 6.1 software adds a new Data Logging function for real-time
analysis. This new function allows you to specify which transport stream events
will be recorded into tab-delimited text files for further analysis.

Master Client
Expert Client
Configuration Client
TMCC Expert Client
You will start the new TMCC Expert and TMCC Configuration Clients from the
Port Manager Panel of the Master Client.
When analyzing in ISDB transport stream, the Expert Client will display the
ISDB specific tables BIT, DCT, DLT, and SDTT in addition to other tables
common with the MPEG-2/DVB/ATSC standards. Section analysis, rate errors,
and reports are displayed for the ISDB transport stream as with other
DVB tables.
The Configuration Client allows you to specify to which standard you are testing
an input: MPEG-2, DVB, ATSC, or ISDB.
A new Data Logging configuration panel allows you to enable or disable the
function, select the types of events that will be logged, and set the size and
time-period of the data files.
The new TMCC (Transmission and Multiplexing Configuration Control) Expert
Client is a new application included with version 6.1 of the Tektronix MTS300
MPEG Test System. This client allows you to analyze the TMCC data of an
ARIB-compliant transport stream input real time. You can also analyze an
ARIB-compliant transport stream file stored on your local disk using the TMCC
Deferred-Time Client.
The TMCC Expert client has the following characteristics:
H Indicates the presence of sync bytes (0x47 for TMCC basic streams and W1,
W2, or W3 sync bytes for TMCC data streams)
H Displays the syntax of TMC C data
H Displays Slot, TSID, TS Name, and Modulation mode information
H Displays information, warning, and error messages
H Indicates the presence of TMCC alarm and update flags in the transport
stream
H Displays the overall stream rate
H Provides access to the Stream Recorder client, enabling you to capture all or
part of a TMCC transport stream input
When you use the TMCC client to analyze local transport stream files, the
TMCC Configuration Client is automatically started, allowing you to specify the
file you need to analyze. The toolbar for the Deferred-Time Client provides
buttons with which you can navigate transitions in the TMCC data. Finally, the
stream capture buttons are replaced with buttons that you can use to save all or a
specific part of the transport stream file to a disk.

TMCC Configuration
Client
The new TMCC (Transmission Multiplexing Configuration Control) Configuration client is a new application included with this version of the Tektronix
MTS300 MPEG Test System. This client allows you to set the monitoring,
analysis, and reporting parameters of the TMCC Analysis Servers.
The TMCC Configuration client has the following characteristics:
H Configures the TMCC Analysis Servers to operate in either TMCC basic or
TMCC data stream modes
H Enables you to specify a transport stream ID to analyze using the MPEG-2
Analysis Server (only in the TMCC data stream mode)
H Sets parameters for the following TMCC probes:
H Frame size
H Super frame size
H Modulation mode and slot consistency
H TMCC syntax
H TMCC update counter (only in TMCC data stream mode)
Using these real-time applications, you can continuously monitor an input
bitstream for compliance with the MPEG-2, DVB, ATSC, and ISDB-S/ARIB
digital television standards. You can monitor an array of stream parameters to
ensure decodability, or you can concentrate on just a few parameters for closer
examination.
TMCC Combiner
8
The new TMCC Combiner is a wizard-like application that helps you configure
TMCC information that you want added to the Reed-Solomon area of 204 byte
transport stream packets. Once you specify this information, the TMCC
Combiner re-multiplexes your transport stream file with the added information,
creating a valid TMCC stream.

ARIB Table Editor
The MTS300 ARIB Table Editor allows you to create and change PSI and ARIB
table structures and parameters.
ARIB tables that you can edit using the ARIB Table Editor include the following:
H Broadcaster Information Table (BIT)
The BIT provides name and ID parameters and descriptions of the services
encoded in the transport stream for each broadcaster.
H Download Control Table (DCT)
The DCT provides a list of modules available in the transport stream for
download.
H Download Table (DLT)
The DLT is used to download code to set top boxes.
H Software Download Trigger Table (SDTT)
The SDTT is used to define the service, group, and schedule for items
encoded in the transport stream that can be downloaded.
Deferred-Time System
Analyzer
Deferred-Time TMCC
Analyzer
The Deferred-Time System Analyzer supports ISDB-S/ARIB transport streams.

Performance and Release Issues
This section describes known issues at the time of the MTS300 MPEG Test
System release.
Thomcast Name Change
Real-Time Analysis
Thomcast, Inc. has changed its name to Thales, Inc. The software was completed
before the name change was announced. Some of the opening screens for the
different applications still refer to Thomcast, Inc.
Configuration Profiles (Reference CSEdb19930). To save, load (restore), or delete
Real-Time Analysis 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 MTS300 system configuration, MTS300,isa
member of the Backup Operators group. To add a user or change the group
memberships of a user, log in as the administrator (password = MPEG2)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.
PID Bit Rate Limitation. Each PID of the stream is limited to a bit rate of
98 566 144 bits/s. The bit rates of any PID with bit rates over this limit will be
reported by subtracting 98 566 144 bits/s from the actual value. Therefore, a Null
packet rate of 150 Mbps is reported in the Expert client as 51 433 856 bits/s.
Deferred-Time System
10
Analyzer
Analysis of Large Files (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
suspend or abort most MPEG-2 S ystem Analyzer operations.
Fonts (Reference CSEdb03373). When displaying a large font, some characters are
displayed badly (or not at all) in the packet views. Use a smaller font.

Buffer Overflow using Dynamic Analysis (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)tothe
elementary stream buffer (EBn); therefore, 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.
Timing Analysis using the System Analyzer (Reference N/A). When using the
System Analyzer to examine a partial, filtered transport stream captured with the
Expert and/or Configuration Clients, 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 Expert Client.
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 PID filtered on the Data Storage Configuration tab of the Configuration Client Settings window.
M-TMCC Transport Streams. F or M-TMCC transport streams compliant with the
ISDB-S/ARIB standard, the Deferred-Time System Analyzer is not able to
determine the rate of the transport stream. Use the Deferred-Time TMCC
Analyzer to determine the rate of the transport stream, and then enter the
observed rate in the Analysis/Multiplex Characteristics/Rate dialog before
performing other timing-related analysis.
AC-3 Audio in ATSC Mode. In ATSC analysis mode, if the first AC-3 audio packet
appears more than 3000 packets from the beginning of a transport stream file,
the Deferred-Time System Analyzer is not able to recognize the AC-3 elementary stream correctly. The reason is that the PMT itself cannot determine the
elementary stream type from the ATSC standard. The Deferred-Time System
Analyzer must look into the actual packets containing the AC-3 audio to
recognize the AC-3 audio, but the searching is limited to only the first
3000 packets.

Analysis Server
Open Mux Server
Stream Player
SPI (LVDS) Interface Input
Some MPEG2 and ATSC compliant transport streams use packets with PID 16
to carry video elementary streams. Do not try to analyze transport streams with
video in packets with PID 16 while in the DVB mode. In the DVB mode, the
analysis server expects packets with PID 16 to be NIT sections, complying with
the DVB standard.
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.
The Stream Player is not able to determine the rate of M-TMCC transport
streams. To work around this problem, you can use the Deferred-Time TMCC
Analyzer to determine the rate of the transport stream, and then enter the
observed rate into the Stream Player before you play back the transport stream.
The SPI (LVDS) input (Option LV or MTS3FLV) does not support the use of the
Data Valid signal. If you need to use this signal, the Data Valid signal can be
enabled by performing the work-around procedure described in the DValid.doc
file on the MTS300 Application Software CD-ROM in the Tools directory.
However, this work-around setup will be lost when the instrument is rebooted.
You will have to perform the work-around procedure each time you reboot the
instrument.
Rackmount Installation Kit
ATSC Corrigendum
The kit instructions included with the rackmount kit for the MTS300 system
indicates that the kit is for RFA300 instruments. The rackmount kit is correct for
all instruments using the mainframe common to a number of Tektronix instruments, including the MTM300, RFA300, and PQM300.
The MTS300 system is compliant to the Corrigendum for Program and System
Information Protocol for Terrestrial Broadcast and Cable (A65). The corrigendum is an amendment to the A65 standard that replaces the 2-bit zero field
taking the value 00 with the reserved field taking the value 11 in all P SIP tables.
Disregard syntax errors reported in the Expert client related to this field because
the transport stream being analyzed may not be compliant to the corrigendum.
