Overview
This section provides details of installing and powering up the Tektronix MTM400
MPEG Transport Stream Monitor.
The MTM400 is a single-stream, extended-confidence, MPEG-2 protocol,
monitoring device. It is used to monitor a single transport stream in MPEG-2,
DVB, ISDB and ATSC environments. The MTM400 is a rack-mounted device.
The basic MTM400 provides confidence monitoring by making key measurements
and comparing them with preset parameters; inconsistencies can be reported as
varying levels of error. Integrated flexibility allows the software to be upgraded
with diagnostic capabilities and to supply detailed information to enable fault
identification and analysis.
The user interface is accessed through a Remote User Interface (RUI). The RUI
allows the status of the MTM400 to be determined from anywhere in the world and
provides remote control of the measurements and configuration to the
administrator. The RUI is accessed through Microsoft Internet Explorer (Version 6
SP 1); the Microsoft Java Virtual Machine (Version 5.00.3809) must also be
installed.
The user interface can also be accessed by the Multi-Layer Monitor (MLM1000)
and the Web Monitoring Systems Manager (WebMSM),
The WebMSM is a Java application that is installed on any personal
computer; as for the RUI, Microsoft Java Virtual Machine (Version 5.00.3809)
must be available. The installation, configuration, and operation of the WebMSM
is described in the WebMSM User Manual (071-1239-xx).
The RUI and the WebMSM communicate with the MTM400 through the open
standard Simple Network Management Protocol (SNMP) and Hypertext Transfer
Protocol (HTTP).
ASI (Asynchronous Serial Interface) and SMPTE 310M (Society of Motion
Picture and Television Engineers, 19.392 Mbps only) interfaces are provided as
standard; optional QAM (Quadrature Amplitude Modulation), COFDM (Coded
Orthoganal Frequency Division Modulation), QPSK (Quadrature Phase Shift
Keying) (L-Band), and 8VSB (Vestigial Sideband) interfaces are available as
options.

Licensing
Options and upgrades are enabled using a License Key. A License Key is an
encrypted code that unlocks and enables functions that have been installed on the
Real-Time Monitoring (RTM) device. Using this method, upgrading an RTM
device may simply require the entry of a new License Key.
For new RTM devices, the appropriate License Key is applied during production.
However, it is also supplied as part of the product documentation.
When field upgrade options are installed, you must apply a new license key; this
will be supplied as part of the field upgrade kit documentation.
This user manual describes all available options including field upgrades. The
basic product (with no licensed options) includes the following transport stream
features:

Setting the Font Used By the RUI
If the RUI does not show the program names and logs in the correct character set,
first ensure that the correct standard is selected for the broadcast being monitored.
If the characters are still incorrect, you must configure the RUI to use a font that
supports the characters in use.
1. Locate the file MTM400.INI. This is typically in the Java folder inside the
Windows folder or in your home directory.
This file is formatted in Unix text. If a Unix file-format compatible text editor
(for example, PFE) is not available, edit file in Notepad. Be careful not to add
any new lines; only edit what is there.
2. Within the MTM400.INI file, change UnicodeOn=false to UnicodeOn=true,
save the file, and restart the RUI.
3. The RUI will attempt to select a suitable font installed on the system. If the
displayed characters are still incorrect, close the RUI and reopen
MTM400.INI.
4. Change the UnicodeFont=Arial Unicode MS section to the name of the
TrueType font you want to use, for example UnicodeFont=MS Gothic. Save
the file and restart the RUI.
The default Arial Unicode MS is shipped with many Microsoft products and
operating systems; it includes the whole Unicode character set. This font provides
the best compromise to display the non-English program names and the English
elements of the user interface. If this font is unavailable, similar fonts are
commercially available, for example from Bitstream Inc. (www.bitstream.com).
The preceding instructions relate to running the RUI under the Microsoft Java
Virtual Machine. Some users choose to run the WebMSM under the Sun Java
Virtual Machine, however, this is an unsupported configuration. In this case, the
user should see the Sun documentation relating to modifying ‘font properties’. The
exception is when the RUI is integrated into the MLM1000. In this case, refer to
the user manual (Tektronix part number 071-1433-xx) that accompanies the
MLM1000.

Getting Started
Installing Font Extensions on Your PC
The ARIB specifications for ISDB make use of private extensions to the standard
Unicode character set [0xE000-0xF8FF]. These extensions provide additional
characters and non-standard proprietary characters; they are used to extend an
existing font. Check with the transport stream broadcaster for the availability of
any font extension set for their transport stream. Because these font extension files
are specific to the broadcaster, they are not supplied by Tektronix.
The extension sets are provided as TrueType Extension files (*.tte). Any extension
sets should be installed using the Private Character Editor which is supplied as part
of the standard Windows installation.
The following paragraphs describe the general procedure required to install an
extension set:
1. Select Start => Run.
2. Enter eudcedit and select OK.
3. The Private Character Editor is opened. Close the Select Code dialog box.
4. Select File => Font Links….
5. In the Font Links dialog box, select the Link with selected fonts option. (If
Link with all fonts is selected, the following actions will overwrite any
existing extension sets.)
6. In the Select Fonts box, find and highlight the font to which the extension is
to be made; this font should be the one used in the RUI.
7. Select Save As…..
8. Browse to the supplied TrueType extension file (*.tte) and select Save.
9. In the Font Links dialog box, select OK.
10. Close the Private Character Editor.
To check that the extension has been successfully installed:
1. Open the Character Map application (Select Start => Run and enter
charmap).
2. Select font name (Private Characters) and note the extended character set.
3. Close the Character Map application.
The extended character set is now available for use when the font is selected.

Using WebMSM
Using MLM1000
If you have a system consisting of MTM400 units, you can expand your
monitoring capabilities by using the WebMSM Monitoring System Manager.
The WebMSM software is effectively an installed version of the RUI. The
WebMSM software provides additional functionality by allowing you to create
hierarchical network views of your systems using the WebMSM Configuration
Editor, and monitor and control multiple devices. The WebMSM user interface is
similar to the RUI.
For further information concerning installing and configuring the WebMSM, refer
to the WebMSM User Manual (Tektronix part number 071-1239-xx).
If you have a system with a number of Tektronix monitoring devices, which are
not limited to MTM400 units, you can enhance your monitoring capabilities by
using the MLM1000 Multi-Layer Monitoring software.
User Interface Version
The MLM1000 software manages a hierarchical network of MTM400 units,
waveform monitors, RF monitors and other instruments. Like the WebMSM
software, it is installed on the PC; the MTM400 interface is identical to the RUI.
For further information concerning installing and configuring the MLM1000
software, refer to the MLM1000 Multi-Layer Monitoring Software User Manual
(Tektronix part number 071-1433-xx).
The software version of the user interface (RUI or WebMSM) is shown on the
device information screen (page 3-1). Ensure that the RUI version is the same as
the FW version installed in connected MTM400s.

Time Zones
An inevitable consequence of allowing the RTM device user interface to be
accessed across networks is the crossing of time zones. Various features of the user
interface display timing information, including the Log files. You need to know the
time source being used to record events. Also, when scheduling the loading of
configuration files, time zones must be taken into account (see Scheduling,
page 3-91).
Figure 2-8 shows a typical setup in which an MTM400 is located in Denver and is
monitored from Portland. In local time, Portland is one hour behind Denver. In this
example Universal Coordinated Time (UTC) is 10 p.m. Therefore the local times
in Portland and Denver are 2 p.m. and 3 p.m. respectively.
Portland
Local Time = 2 p.m.
UTC = 10 p.m.

SNTP (Simple Network Time Protocol) A UTC-synchronized time
clock available over the internet. Appropriate IP addresses of
time servers should be available from the System
Administrator.
Local time is the time being used by the remote user interface; it is the local
PC time. It is referenced to UTC (Coordinated Universal Time) and may be
offset to allow for local time variations, for example, British Summer Time =
+60 minutes. The adjusted time is shown. Local time corresponds with the
current Windows clock and time zone parameters.
RTM Device time is the time being used by the RTM device; this may be in a
completely different time zone. It is referenced to UTC (Coordinated
MTM400 MPEG Transport Stream Monitor User Manual 3-9
Device View
Universal Time) and may be offset to allow for local time variations, for
example, British Summer Time = +60 minutes. The adjusted time is shown.
With Real Time Clock selected from the Time Source drop-down list, the RTM
device can be synchronized to local PC time using Sync with Local. Any offset
required (for a different time zone) is entered in the UTC to Time Zone
Offset field in minutes (range: ±12 hours) and activated using Set.
NOTE. There may be a slight delay between the RTM device time displayed and the
actual time on the device due to network delays incurred in retrieving the time.
This is most likely to be seen if you apply Sync with Local and observe that the
Local and RTM Device times are slightly out of step.
With either Longitudinal Time Code or Simple Network Time Protocol selected
from the Time Source drop-down list, the RTM device takes its time from the
respective input. Any offset required (for a different time zone) is entered in the
UTC to Time Zone Offset field (in minutes) and activated using Set.
To use a remote time server, Simple Network Time Protocol should be selected
from the Time Source drop-down list, and the IP address of a suitable SNTP
server entered in the SNTP field.
The network Gateway and Subnet Mask must be set up for the remote server to be
able to communicate (see Network Settings, page 3-7).

SNMP
The MTM400 Simple Network Management Protocol (SNMP) agent is a software
process that responds to queries using the SNMP to provide status and statistics
about the MTM400. This enables management applications to be developed that
can access MTM400 units remotely across a network using SNMP.
Each of the events available from the MTM400 is kept in a database described by a
Management Information Base (MIB). The various values that can be retrieved
from the MIB are called MIB variables. These variables are defined in the MIB for
the MTM400. Each MIB variable is named by an Object Identifier (OID).
The MTM400 MIB is documented in the MTM400 MPEG Transport Stream
Monitor Programmer Manual, Tektronix part number 071-1375-xx.
The MTM400 MIB definition files can be downloaded from the MTM400 using
http://address/mib/adsys.mib and http://address/mib/admpeg.mib.
Communities
An SNMP Community String is like a password. It is sent along with each SNMP
request and allows (or denies) access to the MTM400. Most agents accept a default
password of “public”. Alternative community strings can also be used to enhance
security. The MTM400 uses the standard community string “public”. However, it
allows a secondary community string to accommodate older systems that use
different values and cannot be changed. Even if these values are changed, the
“public” community string can still be used. Read and Write community strings
can be set in the Network Settings dialog (see page 3-7).
SNMP Traps
An SNMP Trap is an unsolicited message from an MTM400 to an SNMP agent
that an event has occurred. Traps provide an immediate notification for an event
that might only be discovered during occasional polling using normal SNMP
techniques.
SNMP traps have a default community string of “public”. An alternative
community string can be assigned in the Network Settings dialog (see page 3-7).

effective bitrate of all the active services in the stream (due to PID reuse the total
effective bitrate may be greater than the transmitted stream bitrate), this ensures
that the NULL PID bitrate shows the true available bandwidth. Bit rates of
individual services are given in the service list. The icons in the service list give an
indication of the program content: video, audio or data.

NOTE. It is possible that in certain transport streams, different programs may
reference a single PID; for example, programs may reference one PCR PID. In
these cases, the PID bit-rate will be included in all the programs from which the
PID is referenced. Therefore the total bit-rate of all the programs may add up to
more than the total stream bit rate displayed at the top of the window.

Bit Rate Limits
For each PID Group, you can set a minimum (
) and maximum ( ) bit rate limit.
If the incoming bit rate falls outside the values that have been set, an alarm is
indicated on the screen by the graphical bit rate bar changing from green to red or
yellow; the corresponding State icon is also set to the correct color. This test can
also activate the external alarm outputs. When enabled, the limits appear as in the
following diagram:
Minimum Limit
Maximum Limit
The maximum and minimum bit rate limits are set in the Limits dialog box; click
on the program bar to open the dialog box:
The maximum and minimum values can be set either by using the appropriate
slider bar or by entering a value in the numeric field. Values are expressed in
kilobytes per second. The Enabled checkbox must be selected before the limit will
be implemented.

Common Elements
Statistical information for each graph is shown at the bottom of each graph. When
enabled, the View Limits checkbox ensures that the parameter limits are shown on
the Y-axis. When disabled, the data is allowed to expand to fill the available
screen. Limits are set using the parameter function on the Test and PID screens.
PCR Inaccuracy (PCR_AC)
The PCR Inaccuracy graph shows the difference between the actual and expected
values for each PCR on the y-axis. Expected PCR values are calculated from the
byte index of the PCR and the overall bitrate derived from the PCR.

Figure 3-15: Stream view - PCR graph - PCR inaccuracy
The MPEG-2, DVB and ATSC standards specify that PCRs must be within
±500 ns of the actual transport rate. By default, the scale is set to ±500 ns. If the
Inaccuracy in any of the displayed PIDs is greater than ±500 ns, the y-axis is
drawn to show the complete range of values as full scale.
The Maximum PCR Accuracy Error can be adjusted for all PIDs as follows:
Tests screen Î 2.4 PCR Accuracy parameter (right-click) Î Max PCR
accuracy error.
For individual PIDs:
PIDs screen Î Test: select PCR Accuracy Î individual PID parameter
(right-click) Î Max PCR accuracy error.
Right-click on the graph and set the limit for each PID.
PCR Arrival
The PCR Arrival graph provides a display of the time interval between successive
PCRs. The interval is displayed on the y-axis. By default (with the View Limits
checkbox enabled) the y-axis scale shows the conformance thresholds for the
DVB, ATSC or MPEG-2 standards.

Figure 3-16: Stream view - PCR graph - PCR arrival
The PCR Arrival graph provides a display of the time interval between successive
PCRs, during the last 256 PCRs. The interval is displayed on the y-axis. Points are
color-coded with respect to the Maximum Repetition Period set in DVB test 2.3
(The DVB default value is 40 ms). Points are plotted in blue when they fall within
the specified period. Any points that exceed the interval are plotted in red. If the
interval exceeds the limits displayed on the screen, the scale is adjusted
automatically as necessary to include the maximum displayed values.
The PCR Maximum Repetition Interval can be adjusted for individual PIDs as
follows:
PIDs screen Î Test: select PCR Repetition Î individual PID parameter
(right-click) Î PCR max repetition interval.
Right-click on the graph and set the limit for each PID.
