Technical Overview
The MTM400 is a real-time MPEG Transport Stream monitor. The MTM400 provides a complete solution for transmission monitoring of MPEG Transport Streams over RF, IP, and ASI interfaces.
The MTM400 uses a single Transport Stream processor platform packaged in a 1 RU rackmount chassis to provide monitoring of a Transport Stream at data rates up to 155 Mb/s*2. The platform is used to provide an extended confidence monitoring product that, with the addition of software options, provides diagnostic monitoring capabilities.
The extended confidence monitor provides the key MPEG tests; this basic level of functionality and low cost enables widespread deployment throughout a transmission network, facilitating rapid fault isolation. The diagnostic monitoring options provide more in-depth analysis of the MPEG Transport Stream including recording capability, PSI/SI/PSIP/ARIB analysis, and unique user-defined template tests to ensure right content, right place, right time. Deployed at key network nodes, the MTM400 equipped as a diagnostic monitor enables the cause of faults to be pinpointed and solved.
Optional IP and RF confidence monitoring interfaces including Gigabit Ethernet, COFDM, 8VSB, Turbo 8PSK, QPSK (L Band), and QAM are available. RF interfaces allow the MTM400 to receive RF inputs and display key RF monitoring parameters including MER, BER, and constellation displays before demodulating the signal to provide measurements on the health of the Transport Stream. Channel polling allows up to 200 channels to be polled sequentially from either the IP or the RF interface*1.
The polling capability for the MTM400 probe, combined with RF and IP interfaces, allows up to 200 RF channels or IP sessions (discovering up to 500 IP sessions) to be monitored in a repeating cyclic measurement process. Control and configuration of the polling is undertaken using flexible XML scripting. This polling ability makes a single MTM400 probe a broader tool, monitoring large numbers of network points in a time-sampled measurement mode.
The MTM remote user interface provides a summary screen for MPEG Transport Stream thumbnails and video metadata support for confidence monitoring. A full set of APIs is available to support displaying this information within network management platforms. This includes video walls that can display up to the full transmitted resolution of the video stream.
*1 Separate data sheet is available.
*2 Maximum Transport Stream bit rate is dependent on Transport Stream content and depth of analysis being performed. Depth of stream analysis is handled gracefully if SI/PSIP max content is exceeded to ensure critical measurements continue to be performed.
Flexible and Upgradeable
The MTM400 provides a flexible solution with an upgrade path, including diagnostic monitoring features that enable customers to build a cost-effective monitoring system to suit their individual requirements. Diagnostic capability can be added to the key monitoring points where Transport Streams are manipulated while extended confidence monitoring probes can be installed throughout the network:
- Triggered recording enables problems to be captured and analyzed in greater depth using offline analysis tools such as the Tektronix MPEG Test System Standalone Software*1
- PSI/SI/PSIP/ARIB SI Analysis and repetition rate graphing allows broadcasters to determine that the system information is present and correct in the Transport Stream
- Automatic Template Generation: Simple automated template generation from reference stream for exception monitoring. Template testing checks a number of key parameters to ensure that the Transport Stream has been constructed as the broadcaster intended. These parameters include the Transport Stream ID and Network ID, the number of programs in the multiplex, that each program has all of its components (Video, Audio, Data, Teletext, Subtitles) and Conditional Access (CA) status
- Bit rate testing determines whether PIDs, programs, services, or user-defined groups of PIDs are within user-definable limits to ensure correct multiplex operation. Tektronix-proprietary PID variability test gives indication of PID bit rate variation to assess effects of statistical multiplexing
- In-depth PCR analysis with graphical results views enable timing and Jitter measurements to be made to ensure correct operation of the network
- Service logging enables verification of service-level agreements to ensure that contractual obligations are met
- Offline analysis software applications for in-depth deferred-time analysis of streams captured using the MTM400 gives Tektronix the most powerful MPEG monitoring diagnostics available in the world today*3
*3 MTS400 Series MPEG Test System offline software tools are available for use with the MTM400. These are standalone software applications intended to run on the customer's control PC. Separate data sheet is available.
Applications
Contribution and Primary Distribution
Digital video contribution and distribution networks carry compressed video from many origination points to multiple delivery points over limited bandwidth links. Delivery of the right content at the right place at the right time is key to efficient network operation and customer satisfaction. Failure to deliver video services at the appropriate Quality of Service (QoS) leads to potential loss of revenue if video content is not delivered per the service-level agreement.
- MTM400’s low-cost extended confidence monitoring enables widespread deployment
- High bit rate capability, up to 155 Mb/s*2, for monitoring Transport Streams carried over GbE/ATM/OC3/SDH
- Bit rate testing and logging enables bandwidth usage to be monitored and Service-level Agreements to be verified
*2 Maximum Transport Stream bit rate is dependent on Transport Stream content and depth of analysis being performed. Depth of stream analysis is handled gracefully if SI/PSIP max content is exceeded to ensure critical measurements continue to be performed.
Cable Head-end Monitoring

QAM signal monitoring
Cable companies need to verify content accuracy at multiple unmanned head-end sites as operations are centralized. Budgets are tight and resources are limited. MTM400 solves these issues:
- The MTM400 is a cost-effective solution which can be used for unattended operation for unmanned regional head-ends
- Network monitoring units linked to central operations center reduces manpower requirements
- Comprehensive coverage of QAM Annex A/B/C RF interfaces allows cost-effective multichannel, multilayer monitoring
- Selection of PLL and AFC characteristics of the QAM interface enables constellation analysis on signals that are too poor for normal operation
Terrestrial Distribution

COFDM QAM64 Constellation

COFDM Channel C/N
Terrestrial broadcasters need to verify accuracy of content at unmanned transmitter sites. They need to check for errors, troubleshoot problems, and capture errors for offline investigation.
- The MTM400 is designed for 24×7 unattended operation
- Low-cost extended confidence monitoring enables widespread deployment
- Centralized, networked operation minimizes staffing requirements
- Remote stream capture means engineers do not have to visit the site
- COFDM and 8VSB RF terrestrial interfaces allow monitoring at the transmitter site or remote off-air monitoring
DTH or Network Operator Satellite Uplink Monitoring
Large numbers of channels may be monitored by limited personnel. A fault on a single signal could result in great customer dissatisfaction and churn. Errors in the stream or incorrect content must be identified before large numbers of viewers are affected. Therefore, operators need to monitor both before and after modulation.
- The cost-effective MTM400 solution provides low cost per stream
- QPSK (L Band) and Turbo 8PSK RF interfaces allow a stream to be monitored both at the ASI/SMPTE310M interface and the RF interface by switching between the two
