Deployed at key network nodes, the MTM400A provides an intuitive and simplified presentation of video quality and diagnostic information, to support delivery of superior QoS levels in an increasingly complex broadcast environment.

Technical Overview

The MTM400A provides a complete solution for real-time transmission monitoring of MPEG transport streams over RF, IP, and ASI interfaces. Powerful confidence monitoring capability and deep diagnostic measurements are both combined into a single integrated solution. This supports Broadcasters, Cable, Satellite and Telecommunication Operators to deliver superior quality of service (QoS) levels with reduced operational expenditure.

The confidence monitoring capability uniquely simplifies DTV monitoring with the FlexVuPlus summary displays, that includes video thumbnail and electronic program guide (EPG) views. This empowers operational staff with the simplest information necessary to ensure their service is delivering above their defined thresholds for superior QoS.

The deep diagnostic options provides engineers with intelligent hierarchical views of network information, media and data to support rapidly identifying the root cause of underlying service problems. These 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.

The MTM400A provides a single transport stream processor platform packaged in a 1 RU rack mount chassis to provide monitoring of SPTS and MPTS transport streams. The optional IP and RF confidence monitoring interfaces including Gigabit Ethernet, COFDM, 8VSB, Turbo 8PSK, QPSK (L Band) and QAM. The RF Interfaces allow the MTM400A 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. The Gigabit Ethernet interface is designed for monitoring networks which carry both multi program transport streams (MPTS) or single program transport streams (SPTS) over gigabit ethernet networks. It monitors the IP key parameters for up to 500 sessions including Continuity Count, Sync Byte and Packet Inter-Arrival Time (PIT).

The channel polling capability for the MTM400A, combined with RF and IP interfaces allows up to 200 RF channels or 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 MTM400A a broader tool, monitoring large numbers of network points in a time sampled measurement mode.

The MTM400A remote user interface provides a highly simplified presentation of video quality and diagnostic information for operations and engineering teams. For a fully integrated monitoring solution network management platforms are supported with a full set of APIs to support wider distributed network intelligence. This also includes video walls that can display up to the full transmitted resolution of the video stream for network operation centers.

Flexible and Upgradeable

The MTM400A provides a highly scalable and field upgradeable monitoring solution to tailor capital expenditure with operational growth. The extended confidence monitoring probes can be installed throughout the network and powerful diagnostic capability can be added to the key monitoring points where transport streams are manipulated.

• Triggered recording to be captured and rapidly analyzed in greater depth using powerful offline analysis tools such as the Tektronix MPEG Test System Standalone Software*².
• 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.
• Exception monitoring with simple automated template generation from reference streams. 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.
• Comprehensive service logging enables verification of service level agreements to ensure that contractual obligations are met.
