Transport Stream Compliance Analyzer − Getting Started
The MTS400 MPEG Transport Stream Compliance Analyzer (TSCA) enables
you to monitor and interpret the contents of real-time, previously recorded or
synthesized transport streams using the latest MPEG, DVB, ATSC, ISDB-T, and
ISDB-S standards.
The TSCA is specifically designed to enable you to quickly locate and identify
problems within a transport stream using a minimum number of mouse clicks.
By quickly identifying the problem areas, the TSCA software helps you save
time during the development and test of equipment, networks, and services. You
can configure the TSCA software to display stream information in user-selected
fonts. This feature enables you to view stream information in your local language
or to use custom fonts.
The TSCA software will run stand-alone on computers with Microsoft Win dows 2000 or Windows XP operating systems.

Deferred and Real−Time Modes
The TSCA can be run in Deferred or Real-Time mode.
The Deferred mode is available on any recommended platform (including the
user’s own PC). In Deferred mode, a static stream can be analyzed and displayed; the content can then be inspected at leisure.
The Real-time mode, with which a live stream can be analyzed, is available
when the TSCA is installed on a Tektronix MTS400 series MPEG Test System
or an MTX100B with an Option 7 interface card. Real-time streams can be
paused for detailed offline analysis and then when the issue has been found,
real-time analysis can be resumed. Real-time monitoring of Video over IP
(internet protocol) is also available as a standalone application on a user’s own
PC.

Transport Stream Compliance Analyzer (Demo) User Manual
Technical Background
TSCA - Getting Started
The analyzer has a client-server architecture. Every time the analyzer opens, it
starts two processes: tsca.exe, which is the client, and MpegCore.exe, which is
the MPEG analysis engine. Additionally, when the analyzer opens for the first
time, another single process, CoreManager.exe, is started. CoreManager.exe
forms an intermediary between TSCA clients and MPEG cores.
The tsca.exe, MpegCore.exe, and CoreManager.exe processes use SNMP
(Simple Network Management Protocol) and HTTP (Hypertext Transfer
Protocol) to communicate. The port numbers used for communication are read
from a configuration file, CoreInfo.xml. In a default installation, this file can be
found in c:\program files\tektronix\mpeg\mts400\apps\tsca\xml\. The default
port range is 15700-15800. These values can be changed if they conflict with
other applications.
On the MTS400 platform, another process, mint.exe, runs from system startup.
This process controls shared access to the MTS400 Series hardware by the
analyzer and player.
User Interface
Program View
You must have local administrator rights to be able to use IP analysis. If you
need to change your rights , please consult your system administrator.
The TSCA software uses a single main program summary window with different
context sensitive views contained within tabbed frames. This provides the
maximum amount of useful information while keeping the screen from appearing
cluttered. From the main window, you can access the following views: Program,
Tests, Tables,PID, Packets, and Interface.
The Program view provides a fast overview of the transport stream contents in
terms of program content, bit rate use by each program, and TR 101 290 test
results. Red, amber and green LEDs highlight errors associated with each
program, or element of a program, within the transport stream. Red LEDs
indicate that there are current errors in the stream, amber LEDs indicate that
errors have occurred but are now clear, and green LEDs indicate that no errors
have been detected.
Errors that are detected at lower levels in the program stream hierarchy propagate
up to the highest level. This allows you to monitor all of the programs in the
stream at a high level and then quickly go to lower levels as necessary to locate a
problem.
Transport Stream Compliance Analyzer (Demo) User Manual
17
TSCA - Getting Started
Tests View
SI/PSI (Tables) View
PID View
The Tests view enables you to isolate errors to the specific tests that have been
applied to the transport stream. The error log is automatically filtered by the
selected test, and can also be filtered by Packet Identifier (PID). In addition to
the standard first, second, and third priority tests included in TR 101 290
standard, tests are available for Program Clock Reference (PCR) jitter and
program/PID bit rate. A variability test enables you to test the changes in the bit
rate of a specific PID, and there are many tests that are specific to ISDB-T and
ISDB-S streams.
The SI/PSI (Tables) view displays the service information tables that have
occurred in the analyzed stream which comply with the selected digital video
standard. This includes MPEG-specific program information, DVB service
information, and ATSC, ISDB program, and system protocol information. The
tables are grouped together by function and hyperlinks enable you to quickly
access related information within other tables.
The PID view displays information about all of the PIDs found in the transport
stream. When you select the transport stream, the associated summary view
provides a PID-oriented overview of the transport stream, displaying the relative
data rates of all of the PIDs contained within the stream. The information can be
displayed as either a bar chart or as a pie chart. Pop up menus enable fast limit
selection and links.
Packets View
Interface View
Each PID is associated with a number of tests. When one or more tests fail, each
failed test will be listed under the relevant PID. Select a specific PID to display a
summary of all the associated tests. Select a specific test to display the Event
Log and Parameters for only that test.
The Packets view displays information about all of the packets found in the
transport stream grouped according to content. These groups include PID value,
SFN mega-initialization packets (MIPs) (DVB only), and ISDB-T information
packets (IIPs). When you select a specific PID or MIP, only packets carrying that
particular PID or MIP are displayed. A section view is also available. Deferred
analysis of PCAP files allows you to see the ethernet packets.
The Packets view is not available in real-time mode. However, packets in a
real-time stream can be examined using the CaptureVu feature.
The Interface view provides a central location for information related to the RF
interface card (where installed).

Triggered Recording
TSCA - Getting Started
The graphical views display a selection of graphs of instantaneous measurements
and measurement trends. Also available are an Event Log and a Parameter view.
The Interface tab is displayed only when an interface is installed.
The CaptureVu feature captures a snapshot of system events in real and deferred
time, and allows you to debug the intermittent and complex problems that
traditional analyzers miss. You can initiate CaptureVu either manually or
automatically by associating a CaptureVu Breakpoint with any test event. When
a breakpoint is detected, either manual or automatic, the stream is paused and an
in-depth deferred time analysis can be performed on stored data. This powerful
debug mode enables fast debugging of troublesome intermittent problems.
During real-time analysis, stream information can only be held for a finite time eventually it will be overwritten by more up-to-date information. Triggered
recording allows a portion of a stream to be recorded and subsequently analyzed
in detail.
The following trigger sources and conditions apply:
H Any test event
H External input; (TTL) edge specifiable
H Date and time
H Recorded file size can be specified
H Pretrigger buffer size can be specified as a percentage of the overall file size
range from 0 – 100%

Interpreting a Stream
You can set up the stream interpretation standard in the following way:
1. Click Change... in the Open Transport Stream dialog box to open the Stream
Interpretation dialog box.
NOTE. The TSCA software analyzes streams in strict accordance with the
standards defined by the digital television authorities: DVB (Digital Video
Broadcasting), ATSC (Advanced Television Systems Committee), and ISDB
(Integrated Services Digital Broadcasting).
The TSCA software uses preloaded scripts which establish the expected content
and syntax of the analyzed stream. The analyzer is supplied with a comprehensive range of scripts, which, in different combinations, can interpret the full
range of digital television standards.
2. Select the Base Standards and then (if available) select the Region. The
analysis scripts that will be used are displayed in the Script Files pane.

If necessary, select a file type from the Files of type drop-down list.
Currently, two types are available: MPEG Transport Stream files and PCAP
files.
H MPEG transport stream files contain interlinked tables and coded
identifiers, which separate the programs and the elementary streams
within the programs.
H PCAP files contain raw packets of network data. A PCAP may contain
more than one session. You will need to select a session using the
Browse dialog box.
2. When you select a stream, the stream name appears in the field at the bottom
of the window.

3. Calculating the Transport Rate. To analyze a transport stream correctly, you
must do one of the following:
H Calculate the bit rate from PCRs (Program Clock Reference) carried in
the stream
NOTE. When the TSCA software analyzes a transport stream, it compares the
bit rate of the stream to the expected rate. Errors are reported based on the
expected rate of the stream. To analyze a stream correctly, it is necessary to
know the original bit rate of the stream or to calculate the bit rate from
PCRs (Program Clock Reference) carried in the stream. PCRs are generated
as a stable clock reference and are added to the stream during its generation. During analysis, the PCRs are extracted and synchronized with a local
clock reference.
H Know the original bit rate and enter it manually
H Use timestamps included with the stream
4. After you select the desired stream, select one of the following methods for
calculating the rate of the transport stream:
H Prescan the first nnn PCRs. When you select this method, the TSCA
software calculates the rate of the stream by prescanning the stream for
embedded PCRs. The entry box lists the number of PCRs that the TSCA
Transport Stream Compliance Analyzer (Demo) User Manual
23
TSCA - Getting Started
software recommends are necessary to determine the stream rate. You
can use the entry box to enter a different number.
H Prescan all PCRs in a file. When you select this method, the TSCA
software calculates the rate of the stream by prescanning the stream for
all of the embedded PCRs.
H Manually set nnnn Mbps. When you select this method, the TSCA
software uses the absolute value (in Mbps) that you enter as the expected
stream rate.
24
NOTE. Timestamps, which are added when the stream is generated, will be
used, if present, and if the Use Timestamps checkbox is enabled. Using
timestamps will override the PCR options (Prescan PCRs and Scan entire
file). The manual bit rate setting will override both PCRs and timestamps.
5. If the TSCA software cannot calculate the bit rate from the embedded PCRs,
or timestamps, a message box is displayed. You must enter an estimated bit
rate before the TSCA software can analyze the stream.
If the CaptureVu feature is to be used, the whole file can be captured or
analysis can be stopped either by a previously set CaptureVu breakpoint or at
a specific packet.
6. To stop analysis at a specific packet, enable Stop Analysis at Packet Index
and enter a packet number.
With a file selected and the transport rate calculation set up, you can start the
analysis (see page 26).

The fields, from left to right, are as follows:
TS Availability Indicates that either the stream bit rate has fallen below
the minimum value or that synchronization has been lost
(see also Sync below). The minimum stream bit rate is
set using the “Min stream bit rate for processing”
parameter, see Parameter Edit, page 118.
Sync Shows the status of the MPEG sync loss test. Loss of
sync during analysis of a stream may mean that analysis
of the complete stream was not possible.

Error Status LEDs
A major feature used throughout the TSCA interface is error status LEDs that
represent the status of the tests applied to associated items, for example,
programs, tests and PIDs. Colors used are as follows:
(Red) Error; test failed
(Yellow) Transient error (error not currently being detected but has
been seen since last reset)
(Green) No error; test passed
(Dark Blue) Warning (Interface tab only)
(Light Blue) Transient warning (warning not current, but has been
detected since last reset) (Interface tab only)
(Gray): Test disabled
(White) Test not applicable or unknown state
(Red) PID referenced but not found in the stream
(Green) PID referenced but not found in the stream.
Applicable test disabled.
When an LED represents a parent node in a tree (for example, a program node is
the parent of elementary stream nodes), the color represents the worst case of all
of its tests and the worst case of all of the tests represented by its child nodes.
Similarly, when an LED representing a parent node in a tree is disabled or
enabled, all subsidiary (or child) nodes are also disabled or enabled to reflect the
state of the parent node. When an LED representing a parent node is reset, all the
child nodes are also reset.
NOTE. The color scheme described here is used throughout the TSCA interface,
for example, the bit rate bars in the navigation views.

Shortcut Menus
Tests can be disabled and enabled as required using the shortcut menu associated
with the LED icon. However, it is important to note that the extent of the action
depends on the hierarchical level of the icon chosen. For example, choosing
Disable from a program node shortcut menu will disable all tests in the program
group.
NOTE. In deferred time, if any disabled events are reenabled at the end of
analysis, the LEDs will become green. You will have to restart the analysis if you
wish to see the status of the test when the test is enabled.
Shortcut menus provide an important way of navigating around the TSCA
application. They are available on most displayed objects, for example, program
tree nodes. These menus provide options relevant to the selected object. For
example, after failure, all tests associated with a node can be reset, by selecting

Program Navigation − Transport Stream Node
The transport stream node represents the entire transport stream in terms of the
programs that it contains. The adjacent LED icon represents the status of the
entire transport stream; any status error in the stream will be represented by this
LED. When this node is selected, the detail view displays the transport stream
summary.
The associated detail view provides a program-orientated overview of the
transport stream, allowing you to see the relative data rates of all of the programs
contained within the transport. A summary of the overall stream is also
displayed. The information can be displayed as either a bar chart or as a pie
chart.
TSCA - Using the Program View
The data rate of a program is the cumulative data rate of all the PIDs that are
associated with that particular program, including PCR and ECM PIDs.
NOTE. Components can be shared between programs, so the overall data rate of
all the programs may appear to be greater than the total data rate of the
transport stream as shown in the status bar.

Bar Chart
You can display the transport stream bar chart by selecting the bar chart icon.
Each program identified in the stream is allocated one row of the table. Related
information includes the overall program status (icon), the program name,
program number, and the maximum, minimum and average bit rates.
In addition to the basic display, you can associate a maximum and minimum
threshold value with each program in the bar chart (see page 125). For deferred
analysis, where these values are set after analysis, the stream must be reanalyzed
for the new values to be applied. In real-time analysis, the new values will take
effect immediately. The color of the bit rate bar indicates that the program has
stayed within the bit rate limits (green) or exceeded the limits (red).

program is color-coded. Related information given includes the overall program
status (icon), the program name and number, and the bit rate. The values given in
the pie chart labels are bit rates expressed as percentages of the overall bit rate.
The Null PID is shown in this view.
The color of the bit rate labels (and the bit rate values in the legend) reflects the
status of the bit rate measurement, for example, green indicates that the program
has stayed within the bit rate limits, and red indicates that the bit rate has
exceeded the limits.

Test Status Panes
Figure 27: Bit rate values display
NOTE. The bit rate value shown in the Status Bar is always the mean bit rate. It
is unaffected by the mean/current selection.
The lower view pane allows you to see a summary of the states of all the
associated tests as well as the event log for the entire transport stream (an
unfiltered event log). The test tabs available will depend on the interpretation
standard chosen. For example, with the DVB interpretation standard, the
available tabs are TR 101 209 and Other. Other interpretation standards will
generate different tabs and different sets of tests (see SI/PSI Nodes, page 171).
When any test in the transport stream has failed (and has not been reset), you can
identify which individual tests have failed by observing the red LEDs.
You can use the shortcut menus to reset and disable tests, to set alarms,

Test Structure
The test tree structure represents all of the tests that can be applied to a transport
stream complying with a particular digital video standard: MPEG, DVB, ATSC,
ISDB-S, and ISDB-T. The standard must be selected before beginning analysis.
The test tree contains nodes for each test that the analyzer can implement.
An example of a tree structure for a selected standard is the TR 101 290 group of
tests for DVB transport streams (shown in Figure 31). The Group node is split
into priority groups: First Priority, Second Priority, and Third Priority. Each of
these priority groups contains a number of individual tests.
Test grouping differs between digital video standards. However, all of the
currently implemented standards contain a subset of the relevant TR 101 290
tests. Note that in standards other than DVB, the tests are not numbered.
Where relevant, PIDs will be associated with a test in the test tree when the test
has either been disabled, or when it has failed.
The LED associated with each node indicates the status of the node and its child
node tests (see Error Status LEDs on page 40). Total entries in the Event Log for
each group of tests and for each test are are indicated in parenthesis; resetting a
group of tests or a test restarts the count in parenthesis.

Using the PID View
The PID view displays information about all of the PIDs found in the transport
stream being analyzed. The navigation view contains the PID tree structure
representing all of the PIDs that have occurred within the transport stream.
In DVB analysis mode, the MPE tab is always present. However, the MPE view
will only be populated when MPE data is present in the stream (see page 133).

PID View − All PIDs
In the navigation view, PIDs are grouped under the following subordinate nodes:
H Reserved PIDs
H Referenced PIDs
H Unreferenced PIDs
H User PIDs
H Obsolete PIDs (deferred analysis only)
The number of PIDs in each group is shown adjacent to the node. The root node
label shows the total number of PIDs found and the Network Name.
When highlighted, the All PIDs node displays in the detail pane all of the PIDs
found in the analyzed stream.
Each of these subordinate nodes contains PIDs belonging to that group. PIDs are
allocated during analysis, and the number of PIDs is identified for each node.
You can also allocate PID numbers to the User PID node, although User PIDs
may not necessarily have been found in the stream. This feature allows you to
compare the properties of one or more PIDs more easily.
The associated summary view provides a PID-oriented overview of the transport
stream, allowing you to see the relative data rates of all of the PIDs contained
within the transport stream. The information can be displayed as either a bar
chart, or as a pie chart. Columns in the summary views can be sorted in
ascending or descending order by clicking on the column header. PID related
information is available under the PID Information tab.
Each PID is associated with a number of tests. If one or more tests fail, they will
be listed under the relevant PID node in the navigation view. Selecting the PID
node will display a summary, in the detail view, of all associated tests that have
been found. Selecting a specific test in the Associated Tests pane will display the
Event Log and Parameters for only that test.

When a PID does not contain PCRs, the main view in the PID pane is the
Associated Tests view. This view lists the tests associated with the selected PID.
The status of the individual tests is indicated with LED icons. Also available are
Bit rate Graphs which show the bit rate of the selected PID in graphical form.
Also on the Associated Tests tab is an event log and a parameters pane. The
event log shows all PID related events. If a test is selected in the PID pane, only
the events associated with that test on that PID are shown. Similarly, when a test
is selected, the Parameters pane shows the parameters associated with that test
(when applicable).
When the selected PID contains PCR information, PCR inaccuracy and PCR
interval data graphs will be displayed in addition to a bit rate graph. When the
transport stream contains time stamped data, the PCR overall jitter, the PCR
frequency offset, and the PCR drift rate graphs will also be available. For
real-time IP analysis, the Packet Interval Timing (PIT) graph is also available
(see page 115).
A Presentation Time Stamp (PTS) graph may also be available on PIDs carrying

Data in the stream is carried in 188- or 204-byte packets. The Packets view
allows you to examine the contents of each packet in the analyzed stream.
The packet navigation view shows a tree structure which represents the packets
within a stream grouped according to content, including PID value, SFN
mega-initialization packets (MIPs) (DVB only), and ISDB-T information packets
(IIPs).
The All Packets, MIP and IIP nodes do not have any child nodes. The All
Packets node represents all of the packets in the transport stream. The MIP node
represents all of the DVB SFN MIPs in the transport stream. The IIP node
represents all of the ISDB-T information packets in the transport stream.
The PIDs node represents all of the PIDs that are of interest. You can add PIDs
in the transport stream to this node, and to PIDs that are contained within the
user PID list.

This section describes the configuration and interpretation of results of the RF
interface cards that can be installed in MTS400 Series MPEG Test Systems.
The interface settings described are as follows:
H QAM (Quadrature Amplitude Modulation) (Annex B II) (see page 88)
H COFDM (Coded Orthogonal Frequency Division Multiplexing)
(see page 91)
H QPSK/8PSK (Phase Shift Keying) (see page 96)
H 8VSB (Vestigial Side Band) (see page 94)
(Refer to the MTS400 Series Technical Reference, 071-1724-xx for the interface
technical specifications.)
Only one RF interface card can be installed in the MTS400. All RF interface
measurements and graphs include a constellation diagram with MER rings,
EVM, SNR, and BER measurements. The installed interface can be used
simultaneously with an IP input. All interfaces have dual-level warning and
failure alarms plus RF drift tests for long term trend monitoring.
The input card screen and configuration of the card will depend on which
interface card is installed.

QAM(B) Interface Settings. The following QAM (Annex B) settings are available
on the Open Transport Stream - Real Time Analysis dialog box, and also in the
Interface tab - Controls area.
Tuner Frequency : This value, set in kHz units, is the center frequency of
the channel to be received. Any frequency can be entered. There is no need to follow a channel plan. The
frequency resolution is determined by the tuner step size
of 62.5 kHz.
Transport Stream Compliance Analyzer (Demo) User Manual
TSCA - Using the Interface View
Modulation Format: This drop down list allows 64 QAM or 256 QAM opera-
tion to be selected. Note that SCTE07 and ITU-Tj83
annex B specify exact symbol rates for the two modulation formats, so there is no dialog box to enter the symbol rate separately.
Interleaving Mode: Interleaving assists in the correction of burst noise in-
duced errors. All interleaving modes mentioned in
SCTE 07 are supported, including all Level II modes up
to I = 128 J = 6.
Carrier Lock: This allows the carrier lock range to be increased from
the normal ±150 kHz to approximately ±500 kHz. This
is useful if you are attempting to lock on to badly mistuned or wandering carriers.
Tuner Phase Noise: This control modifies the carrier loop bandwidth to al-
low the acquisition of noisy carriers. Normal mode is
recommended for general use.
Equalization Range: The channel equalizer can be configured to give a long
equalization range, at the expense of equalizer resolution, or, in normal mode, optimized for typical cable
environments. Normal mode is recommended for general use.
QAM(B) Instantaneous Graphs. The following instantaneous graphs are available
for the QAM (Annex B) RF interface card.
RF Constellation: I and Q data are collected from the QAM front end and
displayed as a conventional constellation of 256 points
by 256 points. The samples collected are not real time,
so there is some dwell (delay) before a complete constellation is displayed. The persistence of the display can be
varied using the Persist slider control at the bottom of
the graph.
MER (Modulation Error Ratio) and EVM (Error Vector
Magnitude) calculations are performed on the constellation data according to the formulas in ETR290-101.
SNR After Equalizer: This graph represents the signal-to-noise ratio over time,
typically over 256 seconds. It is useful for examining
signal-to-noise trends, for example, if an alarm condition
has been breached, the graph can be used to examine
trends in the signal-to-noise performance before the
alarm occurred.
Transport Stream Compliance Analyzer (Demo) User Manual
89
TSCA - Using the Interface View
MER: This graph gives a time record of MER over the last
255 seconds.
Equalizer: This graph shows the status of the equalizer taps, and
gives an estimate of the channel state. If there are echoes
or other time related distortions on the signal, the Equalizer display will display the amplitude of the corresponding tap correction values versus time.
NOTE. The Equalizer graph amplitude values are approximate.
QAM(B) Trend Graphs. The trend graphs extend the principle of the instantaneous
graphs by graphing measurements over longer periods. Each graph is associated
with a measurement that is also displayed in the Readings panel on the right side
of the display. The measurements have status LEDs associated with them.
Individual trend graphs can be opened by making a selection from the drop-down
menu of the Trend graph or from the context menu of the measurement in the
Readings panel.
The following trend graphs are available for the QAM B interface card: RF
Lock, MER, EVM, Pre-RS BER, Input Level, SNR after Equalizer, and Carrier
Offset.
