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 Windows 2000 or Windows XP operating systems.

TSCA Features

H Easy “program centric” user interface quickly isolates information of interest

H CaptureVut technology captures and analyzes system events in real or

deferred time

H In-depth analysis of stored transport streams including support for MPEG,

ATSC, DVB, ISDB-T and ISDB-S table types

H Data summaries and automated filters simplify the analysis of complex

transport streams

H TR 101 290 Priority 1, 2 and 3 tests

(European Telecommunications Standards Institute (ETSI) TR 101 290:

Digital Video Broadcasting (DVB); Measurement Guidelines for DVB

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.

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.

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).
