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.

ATSC, DVB, ISDB-T and ISDB-S table types
H Data summaries and automated filters simplify the analysis of complex

Systems.)
H Syntax analysis and display supported for TMCC and IIP data
H Consistency checks performed between SI, TMCC, and IIP data
H Proprietary PSI/SI syntax section rate error testing
H Error logging
H Suspension of all tests at program changeover based on PMT version change
H DII and DDB error checking
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

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).

CaptureVu Feature
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%
