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

Product Description

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.

H The Details panel displays icons indicating the type, status, and severity of

errors on a transport stream or service.

H Graphical displays that show the structure (hierarchy) of the input transport

stream and display characteristics of each component of the input stream (for example: PID and type allocation, section rate analyses, and timing analyses).

H Report views that indicate the types of errors recorded by the Analysis

Server and the characteristics of the input stream.

H Error views that show specific errors recorded for the various components

of the transport stream; for instance, PMT section rate errors and ETR290 errors.

The Expert Client can display the results of only one MPEG Analysis Server (input) at a time.

Configuration Client. The Configuration Client allows you to perform the following tasks:

H Specify to which standard you are testing: MPEG-2, DVB, ATSC, or ISDB.

H Set, remove, or modify the probes that test transport streams for valid syntax

and semantics and rates.

H Specify the way in which errors are reported in both the Expert and Master

Clients. You can configure each probe to report an error as Critical, Major, Minor, Warning, or as information only.

H Specify the types of transport stream events that are recorded using the Data

Logging function. You can also set the maximum file size and time period of each log file.

Product Description

Stream Recorder Client. The Stream Recorder application allows you to record a transport stream onto the hard drive of the MTS300 system using a VTR-like interface. You can specify the stream format, duration, file name, and location of the recorded file.

The Stream Recorder is governed by the following MTS300 system limits:

H Only one Stream Recorder can be launched at a time on each MTS300

system.

H The Stream Recorder can only record transport stream files with data rates

between 1 Mbs and 140 Mbs onto the hard drive of the MTS300 system on which the application was launched. You cannot record remote transport stream files or use a remote Stream Recorder to record a local transport stream file.

NOTE. It is recommended that you store transport stream files on the SCSI hard drives (E: drive) of the MTS300 system. The response time of the C: drive on the MTS300 system is limited and may affect the performance of the Stream Recorder and Stream Player applications when you try to capture or play back streams with bitrates greater than 30 Mbs.

H If the SCSI hard drives (E:) are 90% or more full, it is recommended that

you use a defrag utility to defragment the SCSI drives. You can use any defrag utility that is compatible with the Microsoft Windows NT 4.0 operating system.

H The MTS300 system is limited to an aggregate data rate of 140 Mbs between

all operating applications. You may have to shut down other MTS300 applications if you need to record a transport stream with high data rates.

NOTE. Only one TMCC Configuration Client at a time can set parameters on a TMCC Analysis Server. If a TMCC Configuration Client is already connected to a TMCC Analysis Server, you can view the current settings, but you cannot change them.

The settings in the TMCC Configuration Client only configure the measurements made by the TMCC Analysis Server, which are displayed in the TMCC Expert Client application. The TMCC Configuration Client settings do not affect the configuration settings in the Configuration Client, which is used to configure the measurements made by the MPEG Analysis Server.

The TMCC Configuration Client has the following characteristics:

SNMP Capabilities

H Uses multiple configuration panels to group related configuration functions.

H Uses a hierarchic navigation panel to select one of the multiple configuration

panels.

H Configures the TMCC Analysis Servers to operate in either TMCC basic or

TMCC data stream modes

H Enables you to specify a transport stream ID to analyze using the MPEG-2

Analysis Server (only in the TMCC data stream mode)

The MTS300 system includes SNMP management information bases (MIB) installed at the following directory location: C:\Mib\. The Tektronix MIB is a textual description of the Analysis Server objects (functions and parameters) that can be monitored and controlled via SNMP. Refer to the user manual or the online help for more information about the networking requirements of the MTS300 system.

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.

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).

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.

There are three methods to shut down the MTS300 system: soft power down, standard Windows NT power down, and hard power down. For the standard and hard power-down methods, it is strongly recommended that you exit all MTS300 applications prior to initiating an instrument power down.

Soft Power Down. The MTS300 system is shipped from the factory with a soft power-down capability enabled. The soft power-down capability allows you to directly exit Windows NT without closing the MTS300 applications first. The MTS300 system will automatically close all open applications and put the instrument into standby mode.

To soft power-down the MTS300 system, perform the following steps:

1. Press and release the On/Stby switch to initiate the soft power-down process. Some applications will prompt you to save unsaved data before exiting.

2. After the MTS300 system goes into standby mode, you can restart the instrument by pressing the On/Stby switch.

3. To completely remove power to the instrument, disconnect the power cord at the rear panel.

NOTE. If the soft power-down feature does not work properly, you can restore the Soft Power-Off Driver by performing the procedure located in the MTS 300

MPEG Test System Hardware and Software Installation Technical Reference

manual (Tektronix part number 071-0667-XX) supplied with the MTS300 system.
