The MTS4SA MPEG Transport Stream Compliance Analyzer (TSCA) enables you to monitor and interpret the contents of real-time IP streams or previously recorded or synthesized transport streams using the latest ATSC, DVB, ISDB-S, ISDB-T and MPEG standards.

The analyzer 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.

TSCA Features:

• Easy "program centric" UI quickly isolates information of interest
• CaptureVu technology captures and analyzes system events in real (IP only) or deferred time
• In-depth analysis of stored transport streams including support for MPEG, ATSC, DVB, ISDB-T and ISDB-S table types
• Data summaries and automated filters simplify the analysis of complex transport streams
• TR 101 290 Priority 1, 2, and 3 tests
• Syntax analysis and display supported for ISDB-T, TMCC, and IIP data
• Consistency checks performed between SI, TMCC, and IPP data
• Proprietary PSI/SI syntax section rate error testing
• Informational logging of detected errors
• Unicode support enables service information to be displayed in Japanese, Chinese, or other languages

Deferred and Real-Time IP Modes
The TSCA can be run in deferred-time. Deferred-time analysis mode is available on any recommended PC platform. In deferred-time analysis mode, a stored stream can be analyzed and viewed at any time. Real-time monitoring of Video over IP is also available as a standalone application for running on a user’s own PC. Using real-time IP analysis, live streams can be monitored on a continuous basis and can also be paused for more detailed deferred-time analysis. Real-time IP analysis can be resumed at any time.

TSCA User Interface
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:

CaptureVu Technology
The CaptureVu technology captures and analyzes system events in deferred time or IP streams in real time, to debug the intermittent and complex problems that traditional analyzers miss. The CaptureVu technology lets the user set a “breakpoint” on a specific test or event, and, when the breakpoint occurs, a dialog will show the breakpoint condition and exact location of the packet within the Transport Stream. The CaptureVu technology automatically pre-buffers the last 200 MB of the signal, pauses the analysis, and launches an in-depth deferred time analysis that lets the user drill down into the problem. The captured stream can also be permanently stored on the hard disk for subsequent re-analysis with the deferred-time TSCA application. This powerful debug mode enables fast debugging of troublesome intermittent problems.

Trigger Sources and Conditions

• Any of the DVB TR 101 290 1st, 2nd, 3rd priority tests or ATSC and ISDB tests
• Multiplex occupancy outside of user defined limits
• Date and Time
• In triggered recording mode, the size of the pre-trigger buffer can be specified as a percentage of the overall file size range from 0 to 100%

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.

A summary view displays key values for each table in a meaningful way. The view includes hyperlinks enabling you to quickly access related information within other tables and views.

When one or more tests fail, each failed test will be listed under the relevant PID. Specific PIDs can be selected to display a summary of all the associated tests. A specific test can be selected to display its Event Log and Parameters.

Packet View
The Packet View displays information about all of the packets found in the transport stream grouped according to content. These groups include PID value, SFN Mega-frame initialization packets (MIPs – DVB only), and information packets (IIPs – ISDB-T only). When you select a specific PID or MIP, only packets carrying that particular PID or MIP are displayed.

Section Graphing
Section repetition interval – This graph displays the interval between two sections of a table on a particular PID.

top >

Sub-table repetition interval – This graph displays the time between receiving one complete sub-table and receiving the next complete sub-table.

PCR Analysis
The MTS4SA Series supports comprehensive PCR measurements to the TR 101 290 standard. When the selected elementary stream PID contains PCR information, PCR trend analysis views are available, displaying graphs of: PCR accuracy, PCR arrival interval, PCR overall jitter, PCR frequency offset, and PCR drift rate.

The MTS4SA Series is also able to display PTS Arrival Interval graphing in real-time or deferred-time as shown.

Event Panel
This panel shows the events for one or more services, depending on the node selected. Individual events are color-coded and shown as blocks; each block (and its associated tool-tip) displays event information extracted from the EIT. When a block is selected, the complete event information is shown in the event detail panel, including a link to the section carrying the information.

Events are color-coded as follows:

• Red: Present Event
• Green: Following Event
• Blue: Schedule Event
• Yellow: (ISDB only) After Event

MPE/IP View Data Broadcast
MPE data (internet IP sessions over MPEG TS) can be viewed as a separate entry for each MPE session, either detected within the TS or manually signaled since the view became active.

Information displayed for each session includes:

• PID
• MAC address
• Network layer source and destination IP addresses
• Transport layer protocol and port numbers
• Total data transmitted by the session so far since monitoring commenced
• Instantaneous bit rate using MGB1 Profile

DVB SFN
For real time, data contained in the most recently received MIP will be interpreted and displayed in a view depicting each field value. TPS MIP, STS time-stamps, and other detailed information are available in navigator views.

Video over IP Analysis and Recording
The Ethernet port fitted as standard to most PCs running the MTS4SA analyzer will provide 10/100 Base-T or Gigabit Ethernet interfaces for monitoring IP streams carrying MPEG video. This allows connection to a streaming IP video source for Video over IP analysis with CaptureVu™ technology. The analyzer allows the selection of any current UDP session on a LAN segment for subsequent analysis and extraction to disk.*¹

*¹Network traffic loading is specified to 100 Mbps maximum bit rate.

Log Entry Format
Each log entry consists of Time stamp taken from the PCRs in deferred time.

• Error Reference.  This would normally be a PID or Program
• Event description can be in local language
• Errors per stream and per PID.  Circular log of 10k entries, with overwrite warning.
• Logs can be viewed in entirely or filtered pertaining to PID, Program Test, or Test and PID
• Log files can be saved in CSV or XML format for subsequent analysis

IP Recording
Time-Stamped transport stream recording can be made with packet arrival time information stored for offline PCR timing analysis. The maximum record length is limited only by available disk space. It is not necessary to pre-allocate a file before recording.

IP Triggered Recording
It is possible to make either an immediate or triggered recording, with the user definable pre-trigger buffer being used to capture stream before, during, or after the trigger point.

Complete Transport Streams are recorded, with recorded file parameters being displayed upon completion. These include file size, bit rate, number of packets, trigger conditions, trigger position, and time.

Multiplexer and DVB/ATSC Table Editor
When testing network elements or set-top boxes, a transport stream of the representative type needed is often not available. Even if there is a similar one, vital components within it may be missing or suffer from a lack of SI (system information) or other tables, or are multiplexed to the incorrect transport stream rate for the application.

Use the Multiplexer/Re-multiplexer/De-multiplexer application to create multi-program Transport Streams with custom SI/PSI/PSIP information for DVB, ATSC, ISDB, and MPEG compliant Transport Streams.

• MPEG-1 Video
• MPEG-1 Audio
• MPEG-2 Video
• MPEG-2 Audio
• AC-3 Audio
• AAC Audio
• All the above are supported in Elementary and PES formats
• PIDs from other transport streams can be imported including any format including H.264 and VC-1
• Other data - the bit rate must be specified

The solution
The multiplexer allows the user to collect together components from streams recorded off hard disk or CD/DVD-ROM, manipulate them in an unlimited manner, and then rebuild a fully compliant output stream. The software’s built-in knowledge of table syntax and descriptors ensures compliance and high quality output of the final multiplexed transport stream.

De-multiplex Existing Streams
The multiplexer accepts any recorded transport stream as an input source. The user can then de-multiplex this transport stream into its component PES. The user can then save the resulting PES and ES streams onto disk. The de-multiplexer is elementary stream agnostic and can be used to extract H.264 and VC-1 Elementary Streams from a Transport Stream.

Regroup Them with Stored Streams
These PES, or elementary video and audio streams, can be grouped together into logical groups – “Programs” of video, audio, and other associated data (such as Teletext/Closed Caption and MHP applications) with the original timing preserved. PIDs can be re-mapped as required.

Component Views and Available Bandwidth View
The Component Bit Durations View graphically displays the durations as well as start and stop times for each video or audio content PID. Duration and start and stop times can be changed by “drag and drop” or numerical entry. The available bandwidth view clearly shows the user how much content can be added into a transport stream so user can expand or optimize.

Map, Check, and Rebuild Your Own Multiplex
Streams can then be rebuilt into a larger multiplex stream and new SI/PSIP tables can be customized and added safely with in-built compliance checks.

Generate Compliant Timing and Output Bit Rates as Required
The multiplexer is able to insert PCRs at the correct repetition rate and also allows the user to specify the PCR repetition rate, if desired.

Create, Add, or Modify PSIP/SI/PSI Flexibility
The multiplexer allows all the standard ATSC/DVB/ISDB and MPEG PSIP/SI and PSI tables and descriptors to be added or edited. Scripting allows new or custom tables to be added. The user is permitted to generate illegal conditions that allow stress of decoder or transmission chain equipment to verify its robustness.

“Expert” and “Standard” Modes
Standard mode will calculate related fields and table pointers. Expert mode is also provided to allow the user to set these to illegal conditions for stress and robustness test of network elements and STB decoders.
