Technical Overview

Increasingly, monitoring of Gigabit Ethernet and RF transmission is becoming essential for efficient MPEG network operations and proactive fault prevention. The MTM400 is the industry-leading solution for 24×7 MPEG network monitoring, and with both RF and IP interfaces is ideally positioned for monitoring trunk IP feeds and RF drops to the end customer. The Gigabit Ethernet Interface, which was announced to the market in August 2006, has successfully provided full TR 101 290 Priority 1, 2, and 3 monitoring on a single session within an IP stream.

The new 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, combined with the ability to construct and manage multicast groups using IGMP, makes a single MTM400 probe a broader tool, monitoring large numbers of network points in a time-sampled measurement mode.

Enhancements included in the new firmware also provide incremental functional performance within the core product, as well as flexibility offered by the polling capability.

The MTM400 GE with Option 7 provides:

  • Broad but shallow IP and narrow and deep MPEG monitoring in a single solution
  • RF and IP polling capability to cost-effectively monitor multiple RF and IP channels
  • Monitoring across both the IP and MPEG layers
  • Optional RF measurement interfaces for network edge monitoring
  • Downloadable remote GUI
  • Integrates through SNMP with large network control systems

Features and Benefits

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.

The Gigabit Ethernet Interface allows monitoring and measurement of key IP parameters Designed for monitoring networks which carry Multiprogram Transport Streams (MPTS) or Single Program Transport Streams (SPTS) over Gigabit Ethernet networks MTM400 Opt. GE provides:

  • Simultaneous monitoring of both IP and MPEG layers to enable rapid fault isolation
  • Comprehensive confidence monitoring of video over IP with optional Gigabit Ethernet electrical and optical interfaces, IP Protocol support including UDP, RTP with Internet Group Management Protocol (IGMP), Address Resolution Protocol (ARP) and Internet Control Message Protocol (ICMP remote ping)

IP session monitoring support for:

  • Discovery of all sessions/flows on the link with RTP/UDP and TS present indicators
  • Session bit rate monitoring
  • Simultaneous IP packet error and TS error*1 status of all sessions

*1 Sync Byte, Sync Error, and Continuity Count.

*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*3
  • 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
  • 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

In addition, key enhancements provided by the v.2.5.x firmware release and new Option 7 are as follows:

  • Channel Polling: Allows up to 200 channels to be polled sequentially from either the IP or the RF interface (requires Option 7 enabled)
  • Monitoring up to 500 IP Sessions: Wide but shallow IP monitoring of key MPEG parameters, including Continuity Count, Sync Loss, Sync byte, and Packet Interarrival Time (PIT)
  • Logging and Trap Enhancements: Provide logging and SNMP trap support for all identified streams to include TS and IP errors
  • Multichannel IGMP: Manually construct and manage groups of multicast (IGMP) streams for monitoring
  • Automatic Template Generation: Simple automated template generation from reference stream for exception monitoring
  • Filtered error logs for all IP sessions, locked session only, and all error entries

*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.


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.

MPEG over IP Distribution

Internet Protocol distribution of MPEG-2, MPEG-4/AVC (H.264), and VC1 encoded material is increasing dramatically due to the low cost, and ease of routing of packet-based transmission networks. While IP distribution has some clear advantages it also brings its own challenges, particularly in terms of ensuring consistent quality of service. MTM400 with its IP interface option provides MSOs, broadcasters, and network operators with the toolset required to monitor and diagnose complex transmission problems seamlessly across an IP to MPEG network.

With dedicated Gigabit Ethernet electrical and pluggable optical Small Format Pluggable (SFP) modules, the IP monitoring option on MTM400 provides all the industry-standard interfaces required to connect to IP-based MPEG transmission and distribution networks.

Additionally the Gigabit Ethernet Interface provides an ASI/SMPTE310M input and output allowing access to a direct de-packetized MPEG stream for analysis and recording. Input source on the Gigabit Ethernet card can be switched between Ethernet Electrical (RJ45) and Ethernet Optical (SFP at Multi Mode 850 nm, Single Mode 1310 nm, Single Mode 1550 nm).
