Applications
Transport Stream
Compliance Analyzer
The MPEG Transport Stream
Compliance Analyzer (TSCA) enables monitoring and interpretation of
the contents of real-time, previously recorded or synthesized transport
streams using the latest ATSC, DVB, ISDB, and MPEG standards.
The analyzer is specifically designed to enable quick location and
identification of 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.
Users 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 can be purchased
to run standalone on computers with Microsoft Windows 2000 or Windows
XP operating systems. Separate packages are available for Deferred-time
Analysis and Real-time Video over IP Analysis. Both packages offer
CaptureVu technology plus IP and TS measurement, logging, and graphing
capabilities.

Deferred and
Real-time Modes
The TSCA can be run in deferred-time or real-time
for analysis of compressed video streams carried over an IP interface.
Deferred-time analysis mode is available on any recommended platform.
In deferred-time analysis mode, a stored stream can be analyzed and
viewed at any time. Using real-time analysis, live streams can be
monitored on a continuous basis and can also be paused for more detailed
deferred-time analysis. Real-time analysis can be resumed at any time.
Real-time video and audio decode enables the user of the analyzer
to select a program from within a Transport Stream and display the
decoded video for viewing or listen to the audio. Video thumbnails
with video wall, summary, and ES header information views enable users
to choose whether to see many channels thumbnails simultaneously or
view detailed descriptions of one at a 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
CaptureVu technology captures and analyzes system
events in real-time and deferred-time to debug the intermittent and
complex problems that traditional analyzers miss. 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.
CaptureVu technology automatically prebuffers 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.
CaptureVu technology also supports triggering events based upon IP
layer measurements providing integrated cross-layer fault analysis
and logging in a single box solution for network fault diagnosis.
Triggered Recording
The TSCA supports triggered
recording, allowing the user to set up a sophisticated trigger condition.
When the trigger condition is met, the live input stream is captured
to disk without stopping or pausing real-time analysis.
Trigger Sources and Conditions
- DVB TR 101 290 1st,
2nd, 3rd priority tests, ATSC, ISDB, or proprietary tests
- IP layer measurements, including PIT tests, RTP dropped packet count
and rate, out-of-order packets count and rate
- Multiplex occupancy
outside of user-defined bit-rate limits
- Date and time
- In triggered recording mode, the size of the pretrigger buffer
can be specified as a percentage of the overall file size range from
0 to 100%
Program 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 DVB TR 101 290, ATSC, or ISDB test results. Red, amber, and green
LEDs highlight errors associated with each program or element. Video
wall, summary, and detail views enable the user to choose whether
to see many channels’ thumbnails simultaneously or view detailed info
of one at a time. Real-time video and audio decode enables the user
of the analyzer to select a program from within a Transport Stream
and display the decoded video for viewing or listen to the audio.
In addition to displaying a video thumbnail, the video format parameters
from within ES headers are also displayed and can be checked for consistency
with Transport Stream layer signaling of video parameters. This crosscheck
enables the operator to ensure that the format of the content in the
stream matches the format that they have signaled. An inconsistency
could cause the STB to be unable to decode video and the viewer to
lose their pictures.
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.
Tests 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 PID. In addition to the
standard first, second, and third priority tests included in TR 101
290 standard, tests are available for PCR timing, IP layer measurements,
and program/PID bit rate. A variability test enables you to test the
changes in the bit rate of a specific PID. In addition to TR 101 290,
there are many tests that are specific to ATSC, ISDB-T, and ISDB-S
streams.
SI/PSI and PSIP (Tables) View
The SI/PSI and PSIP tables view displays the service information
tables contained in the analyzed stream which comply with the selected
digital video standard. This includes ATSC PSIP, DVB, and ISDB service
information and MPEG program-specific information.
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.
PID View
The Packet Identifier (PID) view displays information about
all of the PIDs found in the transport stream. When you select a PID,
the associated summary view provides a PID-orientated 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. Popup menus enable fast limit
selection.
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
or for IP streams, Ethernet packets can be displayed for the session.
These groups include PID value, SFN Megaframe initialization packets
(MIPs – DVB only), information packets (IIPs – ISDB-T only), RTP or
UDP IP packet contents. When you select a specific PID, MIP, or IP
session-only packets carrying that particular PID, MIP, or session
are displayed. For Ethernet packets, the RTP/UDP header information
is displayed in both real- and deferred-time and can be used to display
packet header information and payload.
Section View
The Section View uses customizable script files, which allow
you to specify and view proprietary information.
Tables and
their data source are displayed. This shows the data bytes (in both
hexadecimal number format and ASCII character format), for the selected
table, version, and section. Tables and subtables are easily analyzed
and directly traceable to packet data.
Section Graphing
Section repetition interval – This graph displays
the interval between two sections of a table on a particular PID.
Subtable intersection gap – This graph displays the interval
between sections in a particular subtable.
Subtable repetition
interval – This graph displays the time between receiving one complete
subtable and receiving the next complete subtable.
Timing
Analysis
The TSCA 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.
PCR graphs
are available in real time and deferred time. Time stamping data ensure
that these can be captured and viewed on stream recordings. This time
stamp is compatible with recordings from other Tektronix equipment
including the MTM400 Transport Stream monitor. Selectable MGF filters
provide maximum flexibility and compatibility in these important PCR
measurements. The TSCA is also able to display PTS Arrival Interval
graphing in real time or deferred time.
IP Layer timing can
be analyzed using statistical display of mean Packet Interarrival
time (histograms).
Cross-layer Timing
Provides the user with an at-a-glance view of timing
at IP, TS, and PES layers. This functionality addresses tough unsolved
timing problems introduced by the use of video and audio over IP technologies.
Enables rapid time to insight when diagnosing at which layer a fault
was introduced.
Real-time and Deferred-time Electronic Program
Guide (EPG) View
The EPG view allows at-a-glance
checking across many EIT tables and can be set to any time zone from
local time, UTC, or the transport stream time itself. The number of
days of EPG events displayed are broadcaster dependent, but are not
limited by the analyzer. When a transport stream EPG is selected,
a panel shows the names of the services currently displayed in the
event panel. The services displayed will depend on the node selected
in the navigation view. ATSC, DVB, and ISDB EPGs are supported.
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
tooltip) 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
10/100Base-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.*1
UDP sessions
carrying MPEG TS traffic are indicated and may be selected for analysis
and recording. Transport Stream packets are time stamped as they are
received from any Network Interface Card, allowing PCR measurements
and graphing to be supported. In addition, a display of the mean IP
Packet Interarrival Time (PIT) histogram is available.
*1 Network traffic loading is specified to 100 Mbps maximum
bit rate.
Multiplexer and SI 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/Remultiplexer/Demultiplexer
application to create multiprogram Transport Streams with custom SI/PSI/PSIP
information for DVB, ATSC, ISDB, and MPEG compliant Transport Streams.
A new ISDB-T Single Segment mode is added in version 3.1.
H.264
Elementary Streams may also be multiplexed into a Transport Stream.
H.264 streams both with and without SEI timing messages are supported.
The PTS and DTS generated for non-SEI streams are based upon the POC
(Picture Order Count) information. PTS/ DTS generation may be suppressed
for SEI streams. Bit-rate and frame-rate auto-detection features aid
the import process. These may be overridden for non-SEI streams.
This enables the user to create their own test streams that they
can use to validate and debug their designs more quickly, and also
to create errored streams to perform parametric stress testing and
ensure the robustness and quality of their MPEG-2 or H.264 implementation.
The Tektronix Multiplexer/Remultiplexer/Demultiplexer Application
Supports:
- MPEG-1 Video
- MPEG-1 Audio
- MPEG-2 Video
- MPEG-2 Audio
- MPEG-2 AAC Audio
- AC-3 Audio
- H.264 ES (both with and without optional
SEI timing messages)
- MPEG-2 Video PES (packetized elementary
streams)
- MPEG-2 Audio PES
- AC-3 Audio PES
- 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.
Demultiplex
Existing Streams
The multiplexer accepts any recorded Transport
Stream as an input source. The user can then demultiplex this transport
stream into its component PES. The user can then save the resulting
PES and ES streams onto disk. The demultiplexer is an elementary stream
diagnostic 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 remapped 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 built-in 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.
Wizards for Common Tasks

new transport streams
- Specify ATSC, DVB, ISDB, and MPEG standards
- Add programs
- Add events
Buffer Analyzer
When developing professional and consumer equipment, particularly
encoders and set-top boxes, the characteristics of the test streams
being either generated or used as stimulus need to be ascertained.
Of critical importance amongst these characteristics is adherence
to the buffer model. That is, when the stream is processed by a receiver,
will any of the internal buffers be caused to either under- or overflow.
Consequences of these conditions will be freeze frames and receiver
resets.
There are two types of buffer model. The one to use
by the receiver is signaled within the Elementary Stream itself. The
T-STD method is based upon the DTS values within the PES header and
can be used for any contained CODEC type. Additionally, certain video
CODECs such as MPEG-2 and H.264/AVC may contain buffer parameters
within the ES itself. The Buffer Analyzer verifies conformance of
a stream to the T-STD model. Verification of the H.264/AVC HRD method
is covered by the MTS4EA product.
The Tektronix Buffer
Analyzer Application Supports:
- MPEG-2 Video
- H.264/AVC (MPEG-4 part 10)
- MPEG-2 Audio
- MPEG-2
AAC Audio
- AC-3 Audio
- PSI (ISO/IEC 13818 parts 1)
The Solution
The Buffer Analyzer accepts any recorded
Transport Stream as an input source. The TS is then demultiplexed
into its component PES, grouped by Program. The user can select one
or more PES to analyze for conformance to the T-STD model according
to the buffer parameters for the CODEC type in question. General information
such as profile and level together with any buffer errors are recorded
in a log.
The user may manually set buffer sizes and other
parameters prior to analysis, rather than use those specified by the
standard or signaled within the stream.
Buffer Graphs
The occupancy level for each buffer within the model (3 for video,
2 for audio, and 2 for PSI) is plotted on a graph for each PES being
analyzed. Graphs may be zoomed for ease of use. A Synchronization
feature allows for comparisons at a particular point in time between
each of the graphs and individual log entries.
Trace View
Version 8.0 enhancements have integrated the previously separate
Tracer utility into the Buffer Analyzer application. The Trace view
provides details of the buffer movements for in-depth analysis of
the results. Trace entries are included in the Synchronization feature
for ease of diagnosis.
Buffer Model Results (BMR files)
The analysis results will be stored in a .bmr file to save having
to re-analyze the same file. Results files may be opened directly
in the Buffer Analyzer, whereby logs, graphs, and Trace contents (max
7000 entries) are repopulated. They are far smaller than the original
TS files and thus useful to add as e-mail attachments.
