Product Overview

The MTS300 MPEG Test System is a component of the Video Quality of Service (VQoS) products offered by Tektronix. The MTS300 system (see Figure 1--1) is a high-performance MPEG protocol diagnostic and analysis tool that provides you with innovative solutions to meet the challenges of designing, verifying, and characterizing products and systems using MPEG-2 technology.
The MTS300 system offers powerful acquisition and computational capabilities for analyzing designs based on MPEG, DVB, ATSC, and ISDB standards. These flexible and expandable capabilities include real-time monitoring, data rate analysis, and Tektronix-exclusive timing analysis to help diagnose the most challenging problems and characterize real-time performance.
NOTE. Refer to the MPEG-2, DVB, ATSC, and ISDB-S/ARIB standards for detailed information about the syntax and semantics of each system.
The deferred-time (off-line) analysis provided by the MTS300 system helps you fully verify compliance to standards and diagnose problems in complex transport streams. Easy-to-use transport stream capture, playout, and on-line storage lets you build extensive suites of test streams, and then use these streams to exercise your designs. Additional stream editing capability, with error and jitter injection and real--time multiplexing, gives you the ability to create and playout test sequences that fully stress and characterize design parameters.
Each test system can monitor up to two transport stream inputs simultaneously and accepts inputs in the following electrical formats:
H ASI/M2S (the test system automatically detects the format)
H SPI (LVDS parallel); available when you order the MTS3FLV upgrade
H DHEI (GI Digicipher II): available when you order the MTS3FDE upgrade
H SSI (SMPTE 310M); available when you order the MTS3FSS upgrade

Server Manager. The Server Manager is the process that makes the results of the Analysis Servers and other real-time application servers available to Master Clients. The Server Manager starts automatically when you start the transport monitor. Only one Server Manager can run on a test system.
The Server Manager process interacts with the following entities:
H The Analysis Server sends analysis results (called traps)totheServer
Manager.
H The Stream Player, Stream Recorder, and optional OpenMux (MTS300,
Option OM) servers send state traps to the Server Manager. Unlike the Analysis Server traps, the traps sent by these servers is limited to
H The Master Client displays the data collected by the Server Manager.
Analysis Servers. The Analysis Server is the process that actually analyzes transport stream inputs. Each Analysis Server process consists of one MPEG Analysis Server and one TMCC Analysis Server . Each MTS300 system can support up to two Analysis Server processes of each type simultaneously.
The Analysis Server processes interact with the following entities:
H The Server Manager collects the Analysis Server results (called traps).
H The Expert Client displays the results of the MPEG Analysis Server directly.
Likewise, the TMCC Expert Client displays the results of the TMCC Analysis Server .
H The Configuration Client sets the monitoring and analysis parameters for
each MPEG Analysis Server process operating on the inputs to the MTS300 system. Likewise, the TMCC Configuration Client sets the monitoring and analysis parameters for each TMCC Analysis Server process.

Product Description
Master Client. The Master Client application provides an intuitive interface for controlling and monitoring the status of the I/O ports on the MTS300 system. You can run only one Master Client on each MTS300 system. In a network environment, if a remote MTS300 system has a Master Client open, you must shut down the remote Master Client before you can connect your local Master Client to the Server Manager running on the system.
NOTE. Each MTS300 system is limited to operating two Analysis Server processes of each type at a time, and can run only one Stream Player, one Stream Recorder, and one OpenMux application at a time. In addition, the MTS300 system is limited to an aggregate data rate of 140 Mbs between all operating applications.
From the Master Client, you can perform the following tasks:
H Monitor and analyze MPEG transport streams in real time using the Expert
Client and Configuration client applications.
H Monitor and analyze single- and multi-program TMCC transport streams in
real time using the TMCC Expert Client and TMCC Configuration Client applications.
H Record and playback MPEG and TMCC transport streams using the Stream
Recorder and Stream Player applications.
H Generate multiplexed transport streams in real time using the OpenMux
application (MTS300, Option OM).
The Master Client uses three areas to display different type of information:
H The I/O Port Manager panel displays icons representing real-time application
servers and the input and output ports configured on your test system.
H The Services panel displays icons for the services (also called programs)
encoded in the transport stream you are monitoring.

Connecting MTS300 System I/O Ports

Figure 2--4 through Figure 2--11 show the available input and output (I/O) connector configurations on the MTS300 rear panel. For I/O port specifications, refer to the Specifications section beginning on page 3-1. Use the I/O ports that best suit your operating environment and signal sources. A description of each connector type follows.
Installation
Input
Trigger Input
Clock Input
Output to Other
Equipment
You must provide input to the MTS300 system to monitor an MPEG-2, DVB, or ATSC bit stream. The MTS300 system I/O ports can be ASI serial, SPI (LVDS), DHEI (GI-Digicypher), or SSI (SMPTE310M). To change the configuration, refer to Configuration Client Reference in the MTS300 MPEG Test System Real-Time Analysis User Manual.
The trigger input accepts a TTL level (0 V to +5 V) signal you can use to control capture of the MTS300 system input stream to the system disks. You can configure the system to start/stop data capture on either the rising edge (low to high transition) or the falling edge (high to low transition) of the trigger signal. Refer to the MTS300 MPEG Test System Real-Time Analysis User Manual for further information on capturing transport stream inputs.
Each output port has a corresponding clock input which can be used to clock the transport stream output when using Stream Player. The clock rate is at the byte rate of the transport stream for the ASI/M2S and SPI (LVDS) formats. The clock rate is at the bit rate of the transport stream for the SMPTE310M (SSI) and DHEI (GI Digicypher) formats.
Applications generating an output will do so on the I/O port to which the application has been assigned. Applications requiring an input have an output activation option that will loop-through the input signal to the output connector on the assigned I/O port.
When an output port is used to generate signals using the Stream Player or OpenMux applications, the corresponding input port cannot be used.

Networking

This subsection provides the following information:
H Network requirements for the Tektronix MTS300 MPEG Test System
H Network installation procedures for configuring the TCP/IP and SNMP
parameters of your test system
H Network troubleshooting techniques for solving basic networking issues
common to many network installations
Refer to Network Troubleshooting on page 6--14 for information to help you solve problems with installing the MTS300 system on your network.
Network Requirements
The Transmission Control Protocol/Internet Protocol (TCP/IP) protocol stack is pre-loaded on Tektronix MTS300 MPEG Test Systems. The open nature of TCP/IP allows you to create networks using various protocols and signaling techniques. This section lists the physical and network requirements for using test systems over a network.
Physical Requirements. The following list describes the physical requirements for networking MTS300 systems:
H Ethernet network or subnetwork to the MTS300 system
H 10Base-T / 100Base-T network drop to your local MTS300 system
H Network interface card (NIC) and driver
NOTE. The Intel EtherExpress Pro/100B Adapter NIC and E100BT.sys adapter driver are pre-loaded on all test systems; this combination of NIC and adapter driver is the only one supported by the test system.
Network management stations do not have requirements beyond basic connec­tivity between two points; the network adapter at a network management station can be of any type that allows it to communicate over a TCP/IP network. The routers installed in the network convert data to the appropriate format for the protocols used in your network.
2- 12
MTS300 MPEG Test System Service Manual
Installation
Minimum Network Requirements. To use the test system over a network, you must install it in a TCP/IP network. TCP/IP networks have specific addressing and routing requirements that your network administrator will typically have already configured. Use this section as a checklist for the TCP/IP parameters that your network administrator assigns to your test system.
H Unique IP address
H Unique host name
H Subnet mask (if you are installing the test system in a network with multiple
subnets)
H Default gateway IP address (if your environment uses multiple networks or
subnets)
H DNS server IP address(es) (if you use the DNS service to resolve Internet
addresses; some networks use multiple DNS servers)
H WINS server IP address(es) (if your system uses WINS to resolve computer
names to IP addresses; some networks use multiple WINS servers)
Network Installation
NOTE. In order to use test systems over a network, your network administrator needs to assign your host machine an IP address: you cannot use the test system with Dynamic Host Configuration Protocol (DHCP).
This section describes how to set the parameters listed in Minimum Network Requirements, and how to configure test systems to be managed in an SNMP-
based network management environment. The information in this section will not replace the value added by networking professionals and describes only basic network installation procedures.
Setting TCP/IP Parameters. Each network uses specific values for such parameters as IP addresses and default gateways, so the parameter values used in the examples for this section are for illustrative purposes only unless otherwise specified. You can configure test systems as stand-alone instruments which need only minimal network parameters set, or you can configure them to be installed into a LAN or WAN (local or wide area network, respectively).

7. Set the following DNS values as indicated in Figure 2--14:
NOTE. Do not set DNS parameters unless your network uses the DNS service. Setting these parameters when your network does not use this service will make your host machine run very slowly when trying to resolve network addresses.
a. Enter your host machine name provided by your network administrator
into the Host name text box. Host/domain name pairs must be unique.
b. Enter the name of the domain of which your MTS300 system is a
member in the Domain text box as directed by your network adminis­trator.
c. Click Add in the DNS Service Search Order group, and then enter the IP
address of the Domain Name System server in the TCP/IP DNS Server dialog box.

8. Click OK when you are finished configuring the IP Address and DNS tab parameters and are certain that all of the values correct.
9. Restart your MTS300 system or network management station for the TCP/IP changes to take effect.
SNMP Network
Management
SNMP is a communication protocol built on the top of UDP/IP. It implements a set of commands consisting of operations and variables. Equipment or applica­tions (such as the MTS300 test system MTS300 system) that support SNMP present a set of variables that you can modify or consult as well as a set of notifications. All of these parameters are grouped into a Management Informa­tion Base (MIB).
MIBs are specifications containing definitions of management information so that network systems can be remotely monitored, configured, and controlled.
Accessing the MIB files. The Tektronix MIB is a textual description of the Analysis Server objects (functions and parameters) that can be monitored and controlled via SNMP. The MIB text files are installed at the following location:
C:\Mib\
The MIB files are used by the real-time analysis applications and the Stream Player, Stream Recorder, and OpenMux (MTS300, Option OM only) applications.
The MIB file pairs for each application, for example, the RTAv1.mib and RTAv2.mib files, are used for SNMPv1 and SNMPv2 systems respectively.
The operations in SNMP are limited to retrieving the value of management information, modifying the value of management information, and reporting an event.
Retrieval. The most common type of retrieval operation requires that the identities are those that exactly match the identity of returned variables. This retrieval operation is called GET.
For instance, from a DOS prompt window you can run the following command to check that the Analysis Server is running on the first input:
getone -v2c <machineName> rta0 rtaStartStop.0
Where <machineName> is the network name of the test system for which you are trying to determine the Analysis Server status.
MTS300 MPEG Test System Service Manual
2- 17
Installation
Modification. There is one modification operation, which is called SET. The operand for SET is a list of pairs. Each pair consists of the identity of a variable and its desired value. Use this operation to configure and control a managed system.
For instance, from a DOS prompt window you can run the following command (all on one line) to stop analysis on the first input of a named MTS300 system:
setany -v2c <machineName> rta0 rtaStartStop.0
-i stop
Where <machineName> is the network name of the MTS300 system for which you are trying to start the Analysis Server.
To restart the Analysis Server, use the same syntax, but change the -i switch parameter to start.
setany -v2c <machineName> rta0 rtaStartStop.0
-i start
Event Reporting. The SNMP event reporting operation is called TRAP. It specifies an event and a list of pairs. A pair consists of the identity of a variable and its value or values. This operation reports the occurrence of events on a managed system to a list of managers configured to receive events.

Assigning Servers and Generating a Transport Stream

In this part of the tutorial, you will assign servers to specific I/O ports, and then you will generate a transport stream that you will monitor and analyze later in this tutorial. These steps assume you have performed the steps in the Starting and Configuring the Master Client procedure starting on page 2--44.
1. Right click the Free icons in the Port Manager panel, and then assign an Analysis Server to I/O#1 and the Stream Player to I/O#2 as shown in Figure 2--28.

In this part of the tutorial you will learn how to interpret the icons used by the Master Client, and you will learn how the different Master Client panels allow you to see different levels of error details. These steps assume you have performed the steps in the Assigning Servers and Generating a Transport Stream procedure starting on page 2--47.
1. Right-click the Analysis Server icon (the train icon) and select Start Analysis from the shortcut menu. The Services panel (to the right of the Port
Manager panel) should update showing the services that are part of the transport stream you are now monitoring. The display should now look similar to Figure 2--30.
2. Experiment with the icons by right-clicking each and familiarizing yourself with the contents of the shortcut menus.
If your input is displaying any critical or major errors, you will see error icons overlaying the icons in the Port Manager and Services panels. Refer to the online help for descriptions of the error icons.
3. Select one of the icons in the Port Manager panel. Notice the changes to the Details panel and the Selection Indicator bar. Notice also that when you select an icon in the Port Manager panel that the Error gauge changes.
The Error gauge shows you the severity of errors being recorded on the selected item. In step 5 on page 2--46, you set the Master Client workspace to show only critical or major errors. Refer to the online help for descriptions of the error icons.
