Transport Stream

Compliance Analyzer

Transport Stream Compliance Analyzer - Getting Started

The MTS400 Series 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,
and ISDB standards.

The TSCA is specifically designed to enable you to quickly locate and identify
problems within a transport stream using a minimum number of 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 Win­dows 2000 or Windows XP operating systems.

File Analysis and Real-Time Modes

The TSCA can be run in offline (or deferred) File Analysis or Real-Time
Analysis mode.

The offline File Analysis mode is available on any recommended platform
(including the your own PC). In offline File Analysis mode, a static stream can
be analyzed and displayed; the content can then be inspected at leisure.

The Real-time Analysis mode, with which a live stream can be analyzed, is
available when the TSCA is installed on a Tektronix MTS400 Series instrument
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 your own
PC.

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 T ransfer
Protocol) to communicate. The port numbers used for communication are read
from a configuration file, CoreInfo.xml. In a default installation, the path to the
file is c:\program files\tektronix\mpeg\mts400\apps\tsca\xml\. The default port
range is 15700-15800. You can change these values 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 .

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.

User Interface

The TSCA software displays two primary views selected using tabs: FlexVuPlus
and Analysis.

Using the FlexVuPlus window, you can assemble up to four views that you select
from the Analysis window. This allows you to customize the view by selecting
the views that are most relevant to the analysis task. The FlexVuPlus window is
described in detail in the MTS400 Series Quick Start User Manual.

The Analysis window 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, T ests, Tables,PID, Packets, and Interface.

Program View

Tests View

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.

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.

1- 4

SI/PSI (Tables) View

The SI/PSI (Tables) view displays the service information tables that have
occurred in the analyzed stream that 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.

Version 00e

MTS400 Series Analyzer Applications User Manual

TSCA - Getting Started

PID View

Packets View

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.

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 and ISDB-TB
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, you can examine
packets in a real-time stream by using the CaptureVu feature.

Interface View

CaptureVu Feature

The Interface view provides a central location for information related to the RF
and IP interface cards (where installed).

H Test results

H Graphical representation of specific RF and IP readings

H RF and IP readings and control settings

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.

Interpreting a Stream

You can set up the stream interpretation standard in the following way:

1. C lick Change in the opening dialog box to open the Standard 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 that 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.

Figure 1- 4: Stream Interpretation dialog box

3. Select OK.

to the settings that were in effect when the application was last closed.

Off-Line File Analysis

Perform the following steps to start analyzing a transport stream file:

1. In the Open File Analysis dialog box, browse to a transport stream file.

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 File Name field at
the bottom of the window.

3. Calculating the Stream Bit 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

Version 00e

MTS400 Series Analyzer Applications User Manual

1- 11

TSCA - Getting Started

4. After you select the desired stream, select one of the following methods for
calculating the rate of the transport stream:

H Prescan first nnn PCRs. 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 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. The TSCA software calculates the rate of the

stream by prescanning the stream for all of the embedded PCRs.

H Manually set nnnn Mbps. The TSCA software uses the absolute value

(in Mbps) that you enter as the expected stream rate.

NOTE. Timestamps, which may be added when the stream is generated, will
be used, if present, and if either of the Use Timestamps check boxes are
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 PCR s ,
or timestamps, a message box is displayed. You must enter an estimated bit
rate before the TSCA software can analyze the stream.

Interface Card Overview

TSCA - Getting Started

This section describes the configuration and interpretation of results of the RF
and IP Video interface cards that you can install in MTS400 Series MPEG test
systems. The cards all use a common interface protocol for data handling and
firmware upgrading.

The interface settings described are as follows:

H QAM (Quadrature Amplitude Modulation) (Annex B II) (See page 1--88)

H COFDM (Coded Orthogonal Frequency Division Multiplexing)

(See page 1--91)

H QPSK/8PSK (Phase Shift Keying) (See page 1--96)

H 8VSB (Vestigial Side Band) (See page 1--94)

H IP Video Gigabit Ethernet (See page 1--99)

(Refer to the MTS400 Series Specification and Performance Verification
T echnical Reference, 077-0207-xx for the interface technical specifications.)

Only one of these interface cards 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 GbE interface and NIC input. All interfaces have
dual-level warning and failure alarms, and graphs for long term trend monitor­ing.

The input card screen and configuration of the card will depend on which
interface card is installed. (See the following pages.)

H Connection Type: Select the line speed and type of the physical connection

from the drop-down list: Force 10 (Copper), Force 100 (Copper),
Force 1000 (Copper), Force 1000 (Optical), Force 1000 (Optical Rx),
Auto 10/100/1000 (Copper), and Auto 1000 (Optical).

The term Force means that the IP Video interface card will not negotiate a
line speed; the linked device will have to be set in the specified forced speed
mode for this to work. For the Auto 10/100/1000 (Copper) mode, the IP
Video interface card will attempt to negotiate with the linked device for the
fastest available speed denoted by the number following the word Auto.

NOTE. The GbE interface card does not support hubs under any speed setting;
connecting to a hub can cause undesired effects.

Two types of interface are available on the IP Video interface card: copper
and optical. The copper interface supports speed settings at 10 Mbps,
100 Mbps, and 1000 Mbps. The optical interface supports 1000 Mbps only.

The Force 1000 (Optical Rx) mode is a special mode that can work in
conjunction with a network splitter. In this mode, the receive laser needs to
be connected into a valid optical link between two other devices using an
optical splitter. This enables the IP Video interface card to monitor the
communication between other devices.

H MAC Address: Enter the MAC address of the IP Video interface card, for

example, 01-0a-02-0b-03-0c-04. The card is set with a unique MAC address
in the factory; do not change this. The MAC address of your instrument can
be found on a label affixed to the cover of the instrument.

H Network Interaction: Select the way that the instrument interacts with the

connected network: Passive is equivalent to listening, where no interaction
with the network is required. If you require interaction with the network to
receive traffic, such as identifying specific sources or pinging other
instrument, select Active. Selecting IPv4 and/or IPv6 in active mode will
depend on your intended data sources.

The following selections are available:

H Passive (IPv4 and IPv6) - If you select this option, IPv6 Addressing

fields are not used.

H Active IPv4 only - If you select this option, complete only the IPv4

Address field.

1- 20

H Active IPv6 only - If you select this option, complete only the IPv6

MTS400 Series Analyzer Applications User Manual

TSCA - Getting Started

H IPv4 Address: Enter the IP address of the IP Video interface card. This

address will be allocated by your network administrator. The null value is

0.0.0.0.

IPv4 addresses are normally written as four octets in decimal separated by
periods, for example, 192.0.2.235.

H IPv6 Addressing: If you have selected the active IPv6 network administra-

tion, use this field to select the means by which the IP address of the
instrument can be discovered by the network.

H Stateless only - The interface card will use its MAC address and an

address prefix used in periodic advertisement messages generated by the
local router to automatically calculate an IPv6 address (RFC 4862).

H Manual - Enter an address that has been assigned by your network

administrator in the IPv6 Address field.

H DHCPv6 (Dynamic Host Configuration Protocol version 6) - The

interface card will attempt to contact a DHCPv6 server on the network,
which will supply an IPv6 address for the card (RFC 3315).

If you selected manual IPv6 addressing, enter the address in the IPv6
Address field.

IPv6 addresses are normally written as eight groups of four hexadecimal
digits, where each group is separated by a colon (:).
For example, 2001:0db8:85a3:0000:0000:8a2e:0370:7334.
To shorten the writing and presentation of addresses, several simplifications
to the notation are permitted. Your network administrator will be able to
advise you.

A Link Local address is automatically assigned to allow your instrument to
communicate with the nearest network router or switch.

H ASI Output: Set the output format:

H As Received - The IP data is supplied in bursts as they are received

directly to the ASI output port. The data can then be looped to the
processor card for analysis.

H Smoothed - The incoming IP data is buffered in an attempt to smooth the

bit rate before supplying it to the ASI output port.

H VBR to CBR (Variable bit rate to Constant bit rate) - The incoming IP

data is received at a varying bit rate. Null packets are inserted into the
stream to achieve a constant bit rate output. The result can be recorded
and played back with the timing preserved.

H VBR Detection: Enhances VBR detection.

Not Joined No request to join this subscription has been sent, or a Leave

request has been sent for a previously joined subscription.

Processing The Join or Leave request is currently being sent to the network.

Join Requested A Join request has been sent out on the network but no matching

traffic has been detected.

Joined Traffic matching the subscription has been detected on the network.

A session will only cause a match if the destination IP address is the
same as the subscription’s multicast address. If the subscription also
specifies a Source Specific address, this must match the session’s
source IP address.

The Actions button on the right of the Multicast Database table, lists all the
available actions. These include joining, leaving, subscription management, and
setting the supported protocols. It is also possible to populate the database
automatically according to the detected traffic using the Mimic Current S essions
option; this will not overwrite the current subscriptions but will add to them.
Additionally, the context menu for the table includes the option to copy the table
or selected row contents in CSV format to the clipboard. Double-clicking a row
in the table is equivalent to clicking its Join/Leave button. Double-clicking on
the empty space at the bottom of the table will open the Add Subscription dialog
box.

The current Network Interaction setting is displayed above the table. This setting
dictates whether the network card will send outgoing traffic, for example, IGMP
Join messages. Consequently if IPv4 (or IPv6) is set to passive, no IGMP (or
MLD) or Ping messages will be sent by the interface card, and actions that
would produce outgoing traffic will be disabled on the context menus.

IP Traffic Table. This table shows the sessions or “flows” detected by the network
card. The number of sessions and the total bitrate are displayed above the table.
The currently selected session being routed for deeper analysis is shown
highlighted (and is marked in the Active column, if visible). Additionally, the
context menu for the traffic table includes the option to copy the table or row
contents in CSV format to the clipboard.

Double clicking on a row in the table is the equivalent of selecting that session
for deeper analysis. Double clicking on the empty space at the bottom of the
table will open the Add/Update Session Alias dialog box. Note that selecting a
session will automatically set the Session Selection Criteria parameters on the
Configure Interface dialog box.

Aliases. To better distinguish the sessions in the traffic table, it is possible to
create a list of “aliases”, which are names up to 32 characters in length. An alias
will be assigned to a session if it matches the specified destination address, the
optional destination port, and the optional source address. Aliases will be
displayed in the Session Alias column. For adding multiple aliases, it is
recommended to download the Session Aliases list for manual editing in a text or
XML editor. This list can then be uploaded to overwrite the previous list.

Error Status LEDs

TSCA - Understanding the TSCA Window

Error status LEDs are used throughout the TSCA interface to represent the status
of the tests applied to associated items, such as 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.

Context Menus

Tests can be disabled and enabled as required using the context 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 context menu will disable all tests in the program
group.

NOTE. In offline file analysis, 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
want to see the status of the test when the test is enabled.

Context 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
the context menu option Reset All Tests. The context menu options provide both
actions (for example, enable and disable a function) and quick links to associated

Program Navigation - Program Nodes

Each of the program nodes in the transport stream represents a single program
referenced within the stream. When a program node is selected in the navigation
view, the detail pane displays the details of the program. The LED adjacent to
the program node represents the status of its child nodes (elementary streams)
and the related tests.

TSCA - Using the Program View

The program detail view provides you with an overview of the selected program,
allowing you to see the relative data rates and stream types of all of the PIDs that
are associated with the program (including PCR and ECM PIDs). If the program
contains an MPEG2 or H.264 video stream, it is decoded to produce a thumbnail
picture of the content; this is updated during real time analysis. Similarly, where
EPG information is associated with the program, a summary (Now and Next
program) is displayed. PID content is indicated using icons, which are described
on page 1--112. Bar chart and pie chart views are available.

PID related information is available under the Summary tab.

The Thumbnails tab displays thumbnails and details of the streams for each of

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,
and ISDB. 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 1--26). 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 1--43). 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 Tables View

The Tables view (SI/PSI tab) displays service information in tree form, as in the
other navigation views. The tree represents the service information tables that
have occurred in the analyzed stream and which comply with the selected digital
video standard. This includes MPEG program specific information, DVB service
information, ATSC and ISDB program information, and system information
protocol. The tree contains nodes for each table that is found; tables/nodes are
grouped together by functionality. Figure 1--29 shows an example of the Table
navigation view with DVB stream interpretation selected.

Figure 1- 29: Tables view

Every node within the service information tree has a corresponding summary
view. Nodes that represent tables will also provide you with access to the table
structure and hex data (see Tables Detail View - Section View on page 1--69), and
graphical displays of data rates and interval data (see Tables Detail View - SI
Repetition Graphs on page 1--71).

Table Summary Pane

Some of the nodes that represent less common tables or table groups may not
have specific summary views available in the analyzer. In these cases, a generic
summary view is used.

The table summary view provides a summary of the table related information for
the analyzed transport stream. There is a table summary view for every node of
the service information. The content is dictated by the selected node.

All summary views for nodes that represent an individual table or subtable will
display the table identity and version number of the table from which the
information is extracted. Where relevant, links (underlined text) are provided to
associated objects, for example, in the programs summary (Figure 1--30), links
are provided to the individual program summary views. Similarly, arrow icons
provide links to the electronic program guide (EPG) tables. Where the section is
carried on a PID, a link is also provided to the PID view.

Figure 1--30 shows an example of the summary pane with the PMT PIDs node
selected in the navigation view.

T ables Detail View - Section View

The detailed section view is available when the selected node in the service
information tree represents a table or subtable in the transport stream. During
real-time analysis, the view is continually updated.

The subtable identity, version, and section are displayed at the top of the table
pane.

NOTE. In deferred mode, where two or more subtables, versions or sections are
found in the stream, the relevant field is active, and an alternative selection can
be made from the drop-down list.

In real-time mode, only the latest version and section can be viewed.

The table pane shows all fields that make up a section (for example, PMT). The
fields are arranged in a hierarchical order. The presence of subordinate fields is

In the navigation view, PIDs are grouped under the following subordinate nodes:

H Reserved PIDs

H Referenced PIDs

H Unreferenced PIDs

H SI/PSI 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
that are 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 P IDs
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

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 1--123).

A Presentation Time Stamp (PTS) graph may also be available on PIDs carrying
audio and video information. And a PTS-PCR graph showing the variation
between the PTS and PCR values; this can help detect buffering issues.
