MTM400 MPEG Transport Stream Monitor User Manual xiii

Getting Started

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.

Getting Started

Network Installation

The MTM400 is designed to operate in a networked (TCP/IP) environment. The network or system administrator may have already configured the TCP/IP parameters (including the network identity) for the MTM400. If this is not the case, refer to Appendix A: Network Installation for procedures to configure the TCP/IP parameters.

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.

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.

Powering Up the MTM400

After the connections have been made to the unit, all that is required to power up the MTM400 is to apply power. Connect the power cord to a properly grounded outlet. Connect the other end of the cord to the product's power input (see Figure 1-1).

There is no mains disconnect switch. Initialization will begin as soon as power is connected to the power input. The LEDs on the front panel will indicate activity (see Local Indicators, page 2-2). Initialization can take up to 60 seconds.

Disconnect the power cord to remove power.

The Remote User Interface

The Remote User Interface (RUI) provides a means of accessing the MTM400 configuration and monitoring features. The RUI can be run on any personal computer (client PC) that meets the minimum specification and has network access to the MTM400 unit. The full specification is given in the MTM400 MPEG Transport Stream Monitor Technical Reference.

Logging on

To access the configuration and monitoring features of the MTM400, use the following procedure:

1. At a networked PC, launch Microsoft Internet Explorer.

2. In the browser address bar, enter the network identity or IP address of the

MTM400 unit, for example:

http://TSMonitor01 or http://192.201.121.231.

When the Enter key is pressed, a Java applet is downloaded from the

MTM400 unit and launched. The file size is approximately 1.5 MB; the

download time will depend on the network speed and traffic.

CAUTION. The Java applet will not run unless a 'temp' directory is properly configured on the PC.

The Java applet will not run unless the Microsoft Java Virtual Machine is installed. Type ‘jview’ at the command prompt to verify that it is installed and that the version is 5.00.3809 or greater. If it is not installed, obtain the installation file from the Tektronix Web site.

If the Sun Virtual Machine also has been installed, the Sun Virtual Machine must not be set as the default in the Java control panel advanced tab.

or Internet Explorer options,
