MTS 100 MPEG Test System User Manual
Product Description
This section describes the capabilities and components of MTS 100 MPEG Test
System.
Overview
The MTS 100 hardware and software makes it possible to create, generate,
acquire, and analyze MPEG-2 transport streams and DVB multiplexes.
From a single program with one elementary stream to multiple programs with
many video, audio, and data elementary streams, the MTS 100 can create an
extensive variety of transport streams.
Elementary stream files containing both stationary test signals and motion
sequences are provided on the Bit Stream CD ROM. With the MTS100
Multiplexer and Table Editor applications, you can create a variety of transport
stream files that contain one or more of the provided test signals and motion
sequences.
The Data Store system enables output and acquisition of transport streams at
rates from 1 Mbit/s to 55 Mbit/s. Based on the standard 8 Gbytes of hard disk
(18 Gbytes in instruments with serial number B060000 and later) space
available, the MTS 100 can store transport stream data equivalent to over 20
minutes of acquisition or output at 55 Mbits/s. You can also use end-to-start
looping to continuously (and indefinitely) acquire or output up to 8 Gbytes of
transport stream data. Data Store I/O can be through a variety of hardware
connections, including TTL serial, ECL parallel, ECL serial, G.703, and RS-422.
You can analyze transport stream data (acquired by the Data Store System) with
the Analyzer application. The Analyzer provides a graphical view of MPEG and
DVB transport stream; the graphical view gives access to each field—and each
bit, if you wish, in the transport packets, PES packets, and the various PSI and
SI tables.
The platform for the MTS 100 is a Windows NT workstation. The whole system
arrives at your site fully configured and ready to use; it includes the Data Store
System (hardware and software) and five application programs.
Applications
The five MTS 100 MPEG Test System applications are the Analyzer, the
Multiplexer, the PSI and SI Table Editor, the Channel Coder, and Packet Jitter.
MTS 100 MPEG Test System User Manual

Product Description
Analyzer
The Analyzer displays transport stream data in several ways, including the
Hierarchic view, the Interpreted view, and two types of timing display.
Hierarchic View . The hierarchic view provides a diagram of the data components
carried by the transport stream. Icons are used to identify the PAT (Program
Association Table), NIT (Network Information Table), PMT (Program Map
Table), PES (Packetized Elementary Stream), packets, and the three types of
elementary streams (video, audio, and data). Additional icons indicate the PID
(Packet Identification) number for each data component.
Interpreted View. The interpreted view shows every field in the selected transport
packet, table section, or PES (packetized elementary stream) packet. Any packet
in the file may be accessed. Search for errors in this view.
Timing Displays. Two types of timing displays are available: PCR (Program
Clock Reference) contained in the transport packet headers and PTS/DTS
(Presentation/Display Time Stamp) contained in PES packet headers. The PCRs
are shown in a graphical form indicating their arrival time. The graphical display
of the PTS/DTS shows a time line for each access unit (such as a video frame)
indicating data arrival and value of each time stamp.
Multiplexer
PSI and SI Table Editor
Channel Coder
The Multiplexer provides the means to develop a limitless variety of MPEG
transport stream files, using the elementary streams provided.
Transport streams are produced by the software in non-real time, typically 10 to
100 times the play time of the resulting file. A hierarchy display, similar to the
Analyzer, displays the structure of the transport stream.
Up to 20 programs, with 10 elementary streams each, may be included in one
transport stream file.
Data necessary for the DVB IRD (Digital Video Broadcasting Integrated
Receiver Decoder) to automatically configure itself is available in the MPEG2
Program Specific Information (PSI). Digital Video Broadcasting Specific
Information (DVB-SI) adds information that enables DVB IRDs to automatically
tune to a particular service and allows services to be grouped into categories with
relevant schedule information.
The PSI and SI Table Editor allows the user to enter and change the data in the
SI and PSI tables to fit requirements.
The European Digital Broadcasting Project (DVB) has specified a baseline
system for satellite broadcasting. The Channel Coding portion of the specification has the following coding flow:

Product Description
MPEG2 Transport stream file (Multiplexer)
Energy Dispersal — randomizing
Outer Coder RS (204, 188) — for byte error correction
Interleaver — better burst error correction
Inner Coder (Viterbi p/q) — bit error correction
QPSK Modulator
This application provides the defined channel coding for the transport stream file
and also provides the decoding to return the coded file to a standard transport
stream file.
Packet Jitter
In addition to creating error-free transport streams, the MTS100 can also create
transport stream files with known errors.
The Packet Jitter application allows you to create transport stream files with
simulated timing errors that affect the clocks derived from the transport file. This
allows you to test the robustness of decoders under various conditions.

The MTS 100 server and monitor are designed to operate from a single-phase
power source having one of its current-carrying conductors at or near earth
ground (the neutral conductor). Systems that have both current-carrying
conductors live with respect to ground, such as phase-to-phase or multiphase
systems, are not recommenced as power sources. A protective ground connection, by way of the grounding conductor, in the power cord is essential for safe
operation.
WARNING. This equipment is designed for connection to a earth-grounded AC
outlet. The grounding plug is an important safety feature. To avoid risk of
electrical shock or damage to your equipment, do not disable this feature.
The MTS 100 server (the ProLiant 2500) operates from 100 VAC to 230 VAC
power mains.
The monitor operates on either 115 VAC or 230 VAC source also without having
to set a voltage selection switch.

Power Cord Options
The ProLiant server and the monitor both operate on either 50 or 60 Hz line
frequencies.
CAUTION. To prevent damage to the MTS 100 server, you should protect the
instrument from power fluctuations and temporary interruptions with a
regulating uninterruptable power supply (UPS). This device protects the
hardware from damage caused by power surges and voltage spikes. In addition,
it keeps the system in operation during a power failure.
The server and monitor are delivered from the factory with a 60 Hz/117 VAC
power cord, unless one of the power cord options was ordered. Table 1–1
provides a description of the power cord options.

The parallel port must have the software enable key (HASP) installed to operate.
The software is enabled by a software enable key which is referred to as a HASP
(see Figure 1–2). It comes installed on the parallel port and is transparent to
parallel port applications, such as connection to a printer. The HASP must be in
place on the ProLiant parallel port for the MTS 100 to operate. Do not lose the
HASP. The software enabler (HASP) should remain with the MTS 100 at all
times. If the entire instrument is returned for service, ship the HASP with the
server.
CAUTION. Do not lose the HASP (software enable key). The MTS100 will not
operate without it being installed on the parallel port. The software enabler key
(HASP) also is required by the Tektronix Service Center if the ProLiant server is
returned for repair.

ECL Parallel/Serial I/O Port
The ECL Parallel/Serial I/O port receives and transmits MPEG-2 transport
streams at ECL levels. It is a differential, bidirectional port that operates
independently or in conjunction with the ECL Control Port. The port transmits
or receives either parallel or serial data depending on settings made in the Data
Store Administrator application.
Operating Modes. When the ECL Parallel/Serial I/O port is used independently of
the ECL Control Port there are three operating modes:
Slave acquisition. Captures input signals using the clock signal on the ECL
Parallel/Serial I/O port as the timing source.
Master generation. Outputs signals using the MTS 100 internal clock.
Master generation with external clock. Outputs signals using a timing signal
applied to the external clock input (Clk In).
When the ECL Parallel/Serial I/O port is used in conjunction with the control
port, there are three additional operating modes:
Master acquisition. Captures input signals using control signals from the
ECL Control Port to drive the signal source.
Master acquisition with external clock. As above, but uses a timing signal
applied to the external clock input (Clk In) as the clock source.
Slave generation. Outputs signals using the ECL control port inputs as the
timing source.

Asserted Low differential signal.
This serial interface complies with the electrical characteristics of ITU-T
Recommendation G.703 (HDB3 code) for 8.448 Mbit/s and 34.368 Mbit/s.
There are two modes of operation:
Acquisition. Locks to incoming signal and is self clocking.
Generation (internal clock source). Uses an internal clock source.
This interface uses three Data Store circuit board mounted SMB connectors. One
connector is a dedicated input for both bit rates. The other two connectors are
dedicated outputs, one for the 34.368 Mbit/s output and the other for the
8.443 Mbit/s output. To reduce spurious emissions, only the output currently
being used should be connected.
NOTE. Do not leave an SMB-to-BNC adaptor cable on an unused G.703 output.
It will cause the MTS 100 to exceed EMI emission requirements.

10 Mbit/sec. It uses RS-422 voltage levels, with line-to-line input termination of
110 W. The pinout is shown in Table 1–5.

The 10 Mbit Serial port uses the following signals:
Clock Input
Data In and Data Out. These are MPEG serial bit streams.
Clock In and Clock Out. These are continuous data transmission clocks.
You can choose from three modes of operation:
Acquisition. Captures an input signal using external timing reference.
Internal generation. Generates an output signal using the MTS 100 internal
clock as the timing reference.
External generation. Generates an output signal using the Clock input as the
timing reference.
The Clk In connector provides optional timing input for the ECL Serial, ECL
Parallel, TTL and 10 Mbit Serial outputs. Its maximum operating frequency is
45 MHz.

TTL 50 Serial Port
(Data & Clock I/O)
The TTL 50 W Serial Port receives and transmits at TTL levels. It consists of
clock and data inputs with dedicated connectors. The Data signal is a serial bit
stream, and the Clock signal is a continuous data transmission clock. The
maximum operating frequency is 45 Mbits/s.
There are three modes of operation:
Acquire. Captures an input signal.
Internal Generation. Generates a signal that is locked to the internal clock.
External Generation. Generates a signal locked to an external reference (the
Clock Input).
Cables and Mating Connectors for MTS100 Inputs/Outputs
The MTS 100 comes with adapters for connecting the SMB connectors on the
Data Store to standard BNC connectors. It may be necessary to acquire or
assemble other signal connecting cables and adapters in order to install the
MTS 100 in your facility.
The maximum usable cable length for the various ports, on the MTS 100, are a
function of data rate, cable type, and ambient environment. See Table 1–6. Low
data rates can stand longer cable lengths than high data rates. Low-loss coaxial
cable and low-capacitance properly pair-twisted cable can support longer
transmission paths than miniature coaxial cable or ribbon cable. Excess RF noise
can induce noise in the cable which will reduce the usable length.
The only ports designed as a transmission system are the G.703 I/Os. The others
are basically short-range interconnects. Note that most ports must control cable
delay matching, to maintain clock to data timing margin, or data integrity will
suffer.

The MTS 100 comes with six SMB-to-BNC adapter cables. Three of the adapters
are 75 W to match the impedance of the G.703 inputs and outputs. The other
three adapters are 50 W for use with the TTL Serial Port (Clock and Data) and
Clock Inputs.
Do not leave an SMB-to-BNC adapter cable on an unused G.703 output. It will
cause the MTS 100 to exceed EMI emission requirements.

Tutorials and reference information are provided to help familiarize you with the
six software applications in the MTS 100. The first of three tutorials begins on
page 2–7. The Reference section begins on page 3–1.
The tutorials step you through both analyzing transport stream files and creating
(multiplexing) MPEG2 transport streams files and transport streams. They are
presented in a step-by-step manner and designed so that you can follow along
using your own MTS 100. The files required for these exercises are shipped with
the MTS 100.
The Reference section explains all of the commands available from each of the
six applications that are part of the MTS 100 package. The explanations are
given in the following order: Menu Bar commands, Command Buttons, and
finally commands that can only be accessed through “mouse-clicks”.
Getting Elementary Bit Stream Files
CD ROM
The standard configuration of the MTS 100 MPEG Test System contains several
video and audio elementary stream files and a sample transport stream file.
These files contain pictures, common industry test signals, and sample signals in
MPEG-2 format. They may be used for the following tutorials and for constructing your own transport streams.
There are two sources of additional elementary stream files: a CD ROM (part
number 063-1914-0x) that is supplied with the instrument and the Tektronix
FTP site.
To use files from the CD ROM, either copy the files to the appropriate directories on the MTS 100 system disk (drive C) or leave the CD ROM in drive D.

2. Select Stream from the list of File Types.
3. Select SAMPLE.TRP from the file name list.
4. Choose OK. Figure 2–8 shows the resulting document window. This is the
hierarchic view of the multiplex encoded in the sample transport stream.
NOTE. The Analyzer cannot generate a hierarchic view if the stream does not
contain a PAT (program allocation table, PID 0) or PMT (program map table).
The hierarchic view that appears when you first open a file is based on the first
versions of the PAT and PMT tables found in the stream. You can use the Next
command in the Edit menu or click on the Next command button (in the lower
toolbar) to go to the next PSI version, if any, in the stream.
Figure 2–8: The hierarchic view of the SAMPLE.TRP stream
The Hierarchic View
The hierarchic view allows you to select an icon that represents a particular
element in the stream and make a more detailed analysis. When selected, an icon
displays in reverse video. After selection, all the extraction and analysis
functions are available through the toolbars and menus.

4. Close the PID map so you are ready to look at Multiplex Allocation in the
sample transport stream.
You can use the Multiplex Allocation view to discover what fraction of the
transport stream multiplex is used by each PID.
1. Once again, click on the hierarchic view TS icon with the right mouse button
to open the shortcut menu. This time, choose Multiplex Allocation to create
the window shown in Figure 2–20.
2–18
Figure 2–20: The Multiplex Allocation document window
The multiplex allocation pie chart is useful in determining which PIDs are
present in the transport stream and in confirming that each PID is using the
expected amount of the multiplex.
NOTE. PID 8191 is the stuffing PID; it is not shown in the hierarchic view.
MTS 100 MPEG Test System User Manual
2. Close the multiplex allocation window so you are ready to look at the
transport packets of a particular PID with a minimum of clutter.
Additional Information from the Transport Packet Icon
The transport packet (rail car) icon represents transport stream packets that are
identified with a particular PID. Other elements (such as table sections or PES
packets) are the payload contained within these transport packets; the elements
may be fully contained within one packet or constructed from the payload of
several packets with the same PID. The PID number appears under the transport
packet icon. In the hierarchic view, the icon immediately to the right of a
transport packet icon represents the payload.
1. Press function key F2, if necessary, to display hierarchic view values in
decimal base.
2. Double-click on the PID 21 transport packet icon, as shown in Figure 2–21.
Tutorial: Analyze a Signal
Figure 2–21: Double-click on the PID 21 icon
The analyzer opens a window similar to Figure 2–22.

Tutorial: Analyze a Signal
You can search for errors and get additional information about the fields and
field values just as you did with the transport packet at the TS level. The
difference is that now you are looking at only the packets of PID 21, which
contain PMT sections describing program one.
3. Click the Last command button in the lower toolbar to go to the last PID 21
packet in the transport stream (if you have forgotten which button to use,
move the cursor slowly over all buttons in the lower toolbar while watching
the messages in the status bar, immediately below). Notice—by looking at
the item data near the top of the window as shown in Figure 2–23—that
there are only 14 transport packets of the 9300 in the SAMPLE.TRP stream
that are identified with PID 21.
Item data
Figure 2–23: The last PID 21 packet in SAMPLE.TRP
By the way, the item position is the number of the first byte in the packet relative
to the beginning (byte 0) of the transport stream file. In other words, there are
1625260 bytes in the file (and stream) before this packet.
As with the TS interpreted view, you can open a hexadecimal view of the packet
through the Add View command button. Another way to look at the packets is in
a binary view.
1. Click on the Add View button as shown in Figure 2–24.
Figure 2–24: The View Type submenu
2. Select Binary from the View Type submenu. The analyzer opens a window
similar to Figure 2–25.
Notice that the first eight-bit byte, which corresponds to the sync byte (see
the interpreted view in Figure 2–22), is 01000111. Not surprisingly, this is
the binary equivalent of 71 decimal and 0x47 hex. The next three bits
correspond to the following three packet fields, and the 13 bits after that (to
the end of the third byte) correspond to the PID. Sure enough,
00000 00010101 equals 21 decimal.

You can do all the same things at the PAT section level that you can at the
transport packet level. You can search for errors, get information on the fields
and field values, and scroll among the PAT sections contained in the stream.
3. Close this window before you proceed.
The analyzer automatically calculates and checks the CRC of the first PAT
section when opening a transport stream file. Select the second PAT shortcut
menu command, Check CRC, to calculate the CRC (cyclic redundancy code) of
every PAT section in the stream and compare it to the number coded into the
section’s CRC field.
4. Click on the PAT icon with the right mouse button and hold the button down
to show the PAT shortcut menu. Highlight the Check CRC command and
release the button. If no erroneous CRCs are found, the analyzer creates the

Syntax Analysis
Perform a Syntax Analysis on this PMT section.
1. From the Analysis menu choose Syntaxic, as shown in Figure 2–31.
Figure 2–31: Choosing Syntaxic from the Analysis menu
Syntax analysis checks all PMT sections in the stream for errors and variations
from the standard. It searches for errors that are within the PMT itself and
relative to the other tables (NIT and SDT for example). The example does not
have any PMT syntax errors, as shown in Figure 2–32.
2–24
Figure 2–32: The Syntax Analysis message window
2. Click OK to close the Syntax Analysis message window.
Now, the fact that no syntax errors were found in any of the PMT sections does
not guarantee that there are no such errors in the entire stream. Let’s widen the
search.
3. Click anywhere on the hierarchic view window to select it. (Or minimize the
PMT interpreted view window; the remaining, hierarchic view window is
then automatically selected.)
4. Once again, choose Syntaxic from the Analysis menu. This time, the
analyzer searches the entire stream for errors. If it finds any (and it does in
SAMPLE.TRP), it opens a window similar to Figure 2–33.
MTS 100 MPEG Test System User Manual
Tutorial: Analyze a Signal
Figure 2–33: A message window listing syntax errors
Each line in the message window represents one syntax error. You can doubleclick on a line to open an interpreted view of the item that contains the error.
Notice that in this case all errors are in one PES packet. Let’s wait until the
discussion of the PES icon to talk about these errors.
5. Close the syntax error message window before you proceed.
Check CRC
You can check the CRCs in all PMT sections through the shortcut menu just as
you did with the PAT sections.
You can also check every CRC in the transport stream just like you checked the
syntax of all items in the stream:
1. Select the hierarchic view again.
2. Choose Check CRC from the Analysis menu, as shown in Figure 2–34.
Figure 2–34: Choosing Check CRC from the Analysis menu
If CRC errors are found, the analyzer lists the errors in a window similar to
Figure 2–33. Because SAMPLE.TRP contains no CRC errors, however, the
analyzer displays the message window shown in Figure 2–35.

(numbers 11 through 20) in the stream.
T-STD Analysis
7. Select the PCR diagram window again—the window title says: PCR of
SAMPLE.TRP (PID 50, Program 1):1—and notice that the diagram also
shows PCRs 11 through 20.
8. Close all windows except the hierarchic view before continuing with the
tutorial.
T-STD analysis checks the selected program against the (transport stream system
target) decoder model that is defined in the MPEG-2 standard.
1. Select the Options menu and make sure that Visual TSTD and LTW is
selected as shown in Figure 2–41.

MTS 100 MPEG Test System User Manual
Tutorial: Analyze a Signal
Figure 2–42: Choosing T-STD Analysis from the shortcut menu
Because visual mode is selected, the analyzer opens a Buffering Simulation
window similar to Figure 2–43. The window contains dynamic bar graphs of the
video, audio, and system buffers; the graphs show how full each buffer is at a
given point in decoding and change color from blue to yellow to red as buffer
overflow approaches and occurs. Notice that the simulation is not real-time and
may take several minutes. If you have the time, do watch to see what happens, as
SAMPLE.TRP will cause buffer overflows and have errors to report when the
simulation in done.
Figure 2–43: The T-STD Buffering Simulation window
3. If you don’t have the time to let the simulation finish on its own, click the
Abort button in the lower-right of the simulation window. The simulation
pauses and you can choose to resume analysis or close the window.
Buffer overflows occur near the end of SAMPLE.TRP, and the analyzer opens
the window shown in Figure 2–44. Each line of text in the window represents
one error. As the analyzer discovers additional errors, it adds them to the bottom
of the list. At the end of analysis, all activity in the Buffer Simulation window
stops.

Additional Information from the PES Packet Icon
The PES (Packetized Elementary Stream) packet icon represents all packets that,
together, contain a given elementary stream. Individual PES packets are
assembled from the payloads of several transport packets. You can learn more
about the PES packets and their PTS/DTS (Presentation and Decode Time
Stamps) through this icon.
Interpreted View
1. Click on the PID 50 PES icon with the right mouse button and hold the
button down to take a look at the PES shortcut menu, as shown in Figure 2–45.

2. Choose PES Packets from the menu (or release the right mouse button and
double-click with the left button) to open an interpreted view similar to
Figure 2–46.
Notice that the item data (near the top of the window) now includes a Time:
entry. This is the time that the first byte of the packet appears in the transport
stream, relative to the beginning of the stream. The time is included in all
interpreted views that you open after performing an analysis that involve a
multiplex rate calculation. Both the PCR analysis and the T-STD analysis,
performed while looking at the PMT icon, involve a “mux rate” calculation.

This interpreted view offers all of the same options as were given in the previous
discussions. Remember the syntax errors the analyzer reported when you
performed a “Syntaxic” analysis of the entire stream? They are in a PID 50 PES
packet.
3. Click the Next Error button on the lower toolbar. The program checks each
packet in the stream for errors. If it finds an error, it automatically jumps to
the transport packet containing the error. There are several errors in the last
PID 50 PES packet in SAMPLE.TRP, as shown in Figure 2–47. The errors
are highlighted in red on the MTS 100 display.

PTS/DTS analysis extracts the presentation and decode time stamps embedded in
the elementary stream and shows their relative time positions in a graphical
display window. Through this display, you can check that all of the time stamps
“make sense” (PTS must be later than DTS, and both must be after the
associated data arrives) and check for the existence of B fields, which have no
DTS.

Intra (I) and predicted (P) pictures must be decoded before presentation and
therefore have both DTS and PTS. B (bidirection) frames are decoded and
presented at the same time and therefore have only presentation time stamps.
B frames use information in an associated P frame; the P frame must be
decoded before the B frame(s), but is presented after. In the example, then,
the order of frame decoding is IPBB, but the order of presentation is IBBP.

7. Close the NIT section window.
In the course of this tutorial, you have used the MPEG-2 System Analyzer to
perform several kinds of analysis on various stream elements. The analyzer also
has an automatic analysis feature that simplifies evaluation of the entire transport
stream, yet still permits detailed analysis of many types of error.
The following procedure assumes that you still have the hierarchic view of
SAMPLE.TRP open on your MTS 100 display. If you closed that window to
view a DVB stream in the last section of this tutorial, open SAMPLE.TRP again
before you continue.
1. Choose Automatic analysis from the Options menu. The dialog box shown
in Figure 2–59 appears.
2–38
MTS 100 MPEG Test System User Manual
Tutorial: Analyze a Signal
Figure 2–59: The automatic analysis Options dialog box
2. By default, automatic analysis includes all the listed tests. Automatic
analysis takes several seconds to several minutes, depending on the size and
complexity of the file, speed of your MTS 100, and the number and type of
analyses selected through this dialog box. Dynamic analysis, the last
selection in the dialog box, takes much longer than all other tests combined.
If you are following this exercise to familiarize yourself with the analyzer,
click on the Dynamic check-box to de-select Dynamic analysis.
NOTE. The MPEG-2 System Analyzer can conduct three kinds of Dynamic
analysis: T-STD (transport stream target decoder), LTW (legal time window),
and Smoothing Buffer. Automatic analysis includes only T-STD analysis; the
remaining dynamic analyses must be performed manually. Refer to the Reference
section of this manual for more information about Dynamic analysis.
3. Choose OK to confirm the selections and close the dialog box.
4. Choose Automatic from the Analysis menu. The window shown in
Figure 2–60 appears. This Automatic analysis window contains a table that
shows the progress and results of the various tests. As the analysis sequence
proceeds, cells in the Status column change from blank to Running to
Completed. As each test is completed, either OK or Errors (in red) appears in
the corresponding Result cell, depending on the results of the analysis.
If you wish to end the analysis at any time, click Abort after current task, at
the bottom of the window.

Tutorial: Creating an MPEG-2 Transport Stream
This section explains how to create an MPEG-2 transport stream. First, you will
make a simple transport stream file, then a significantly more complex one.
Finally, this section gives a brief introduction of how to send the signal that you
created out one of the ports on the MTS 100 rear panel as an actual transport
stream. There is an optional tutorial following this one that explains how to build
a transport stream file that contains DVB (Digital Video Broadcast) information.
This section steps you through the Multiplexer, Edit Table, and Disk Manager
applications. These procedures are “step-by-step,” so you can follow along with
your own instrument. You will use files provided with the MTS 100.
NOTE. To aid in following along with your own MTS 100, all steps requiring
action are numbered.
Terms
Start the Multiplexer
There are two specific terms used in this section that are not interchangeable:
transport stream and transport stream file.
A transport stream is the signal that comes out (or in) one of the connectors on
the rear panel of the MTS 100.
A transport stream file is a file on a disk. When the MTS 100 sends this file out
one of the rear-panel connectors (properly timed), it becomes a transport stream.
Click on the Multiplexer name in the Tektronix MTS100 V2.1 submenu. This
starts the Multiplexer application as shown in Figure 2–64.

Notice that you are not going to make a transport stream file right away, but
rather a configuration file. Since transport stream files can be huge, they are not
generated immediately. Instead, configuration files (*.cfg) are created first. These
contain all of the information required to make the transport stream. (For more
information on how they work, please see File Conventions, beginning on
page 3–59.)
2. Enter the name “simple” in the File Name text box (the *.cfg extension is

The Duration gauge gives the status of the multiplex operation. The gauge sits at
0% until you tell the application to create the transport stream file. Since this
process often takes some time, the Duration gauge tells what percentage of the
operation is complete.

The Rate gauge shows the percentage of the available transport stream currently
used. Above the rate gauge bar the target multiplex rate. Below the rate gauge is
the amount currently in use, the actual rate. The actual rate is calculated with the
following formula:
Rate = PSI rate + SI rate + Video rate + Audio rate + Data rate
Below the actual rate is the time period when the highest multiplex rate occurs.
The Multiplex window displays the current configuration file in hierarchic form.
Several icons appear in the Multiplex window to represent specific elements of
the transport stream multiplex. Table 2–4 explains these icons.

The simplest transport stream possible would have one program with one
elementary stream in it. In this example, you will put two elementary streams in
one program.
Add an elementary stream to program 1.
1. Select the program 1 icon.
2. Click the Add (+) command from the tool bar (or choose the Add command
from the Edit menu). This opens the dialog box shown in Figure 2–67.

8. Click OK.
NOTE. The List Files of Type box in the Video Stream Selection dialog box does
not specify the .mp2 file extension. However, you may not select “just any file”
for use as a video elementary stream file. If you select an unacceptable file, you
will see the message box shown in Figure 2–72.
Figure 2–72: Click OK and select another (.mp2) file
All the information about the video elementary stream file loads automatically
into the Video Stream dialog box, as shown in Figure 2–73.

Just like the Video Stream dialog box, the Audio Stream dialog box allows you
to edit only the parameters near the bottom of the dialog box. (Learn more about
these parameters under Selecting an Audio Stream, on page 3–93 of this manual.)
The default parameters are acceptable for the current application.
14. Click OK to select the settings and close the dialog box. This returns you to
the hierarchic display of the configuration file as shown in Figure 2–78.
Figure 2–78: The display after an audio file is associated
Notice that 10KHZ.MP2 is now associated with the Audio Icon and the
Multiplexer Rate gauge is now a little closer to full with the addition of the audio
stream.
You would follow a similar procedure to associate a file with the Data icon.
15. Double-click on the Data icon to open the Data Stream dialog box as shown
in Figure 2–79.

Notice that this dialog box does not have as much information in it as the Video
Stream and Audio Stream dialog boxes. This is because it does not require
elementary streams — a file of any type is acceptable.
16. Click Cancel to close this dialog box without entering a file.
17. Select the Data icon again. This time you will delete it.
18. Choose either the Delete (–) command button from the tool bar or Delete

Create the Transport
Stream File
You are ready to create a transport stream file.
1. Choose Go from the Multiplex menu, or Go from the tool bar. The Multiplex
Output File dialog box appears as shown in Figure 2–82.
Figure 2–82: The Multiplex Output File dialog box
NOTE. The transport stream files can be large. Make sure you have adequate
space on the selected drive before beginning.
You can create the transport stream file directly on the Data Store Board hard
drives by placing the Multiplex Output file in either c:\carb0\mono or
c:\carb0\loop.
Notice that the current configuration file name becomes the default transport
stream file name (with the file name extension changed to .trp).
2. Choose OK to begin creating the simple.trp transport stream file in the
default directory (c:\mts100\cfg-trp). As the MTS 100 generates the transport
stream file, the Duration gauge fills, showing the status of the operation.
When generation is complete, the gauge reads 100% and the Information
message box appears to indicate that the Transport Stream has been
multiplexed.
3. Click OK to continue. The multiplex display resembles Figure 2–83.
MTS 100 MPEG Test System User Manual
2–59
Tutorial: Creating an MPEG-2 Transport Stream
Figure 2–83: Transport stream creation is complete
You have now successfully created an simple transport stream file. Next you will
make a more complex transport stream file.
Making a Complex Transport Stream File
Now you are going to add to simple.cfg file to create complex.cfg, a more
complicated configuration file. Start at the point where you left off (as shown in
Figure 2–83) from the previous steps.
1. Choose Save As from the File menu. The standard Windows Save As dialog
box appears.
2. Enter “complex” in the File Name text box.
3. Choose OK. This saves the information in simple.cfg to a new configuration
file called complex.cfg, creates a new .pmt file (called complex.pmt), and
places the name “complex” in the window title. (Notice that the Duration
gauge has also reset itself to 0%.)
