Introduction
The MTM400A provides a complete solution for real-time transmission
monitoring of MPEG Transport Streams over RF 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 QoS levels with reduced operational expenditure.
Deployed at key network nodes, the MTM400A provides an intuitive and
simplified presentation of video quality and diagnostic information. This
supports the delivery of superior Qualify of Service (QoS) levels in an
increasingly complex broadcast environment.
When used together with VQNet™, facility and network-wide views allow
engineers to sectionalize network problems.
Features & Benefits
Multilayer, multichannel, remote monitoring and measurement at RF
and TS layers to DVB, ATSC, DCII, and ISDB-T/Tb standards with
content-checking support for both MPEG-2 and H.264/AVC
Displays key RF monitoring parameters for DVB-T and DVB-S/S2
interfaces to provide early indication of signal degradation before any
picture impairment is visible to the end customer (Note: In DVB-S2
mode only Transport Stream inputs are supported)
No additional analysis software is needed; all confidence and diagnostic
analysis is carried out from the MTM400A alone
When used in conjunction with the VQS1000 Video Quality Software
application, provides reliable and sophisticated analysis algorithms
applied to decoded MPEG-2 or H.264 video to identify stuck, black,
macro blocking, and compression artifacts
Data Sheet
Product Information
Critical RF measurements; MER and EVM, constellation displays, RF
levels, channel power, SNR, BER, Phase Noise, and Impulse Response
Provides early indication of signal degradation before any picture
impairment is visible to the end customer
DVB-S2 interface includes 16 and 32APSK for contribution and
distribution applications
Video/Audio content checking for both MPEG-2 and H.264/AVC
Thumbnail decode and display of multiple channels, simultaneously
provides a visual check of content with encoding parameters available
to the user (such as codec type, profiles and levels, aspect ratio,
program guide event information, etc.)
Backhaul of actual video and/or audio allows content to be fed back
to the central monitoring point to see and hear the content being
broadcast (encrypted content can be routed to a STB for hardware
decode)
FlexVuPlus™ configurable windows with DVB-S2 display.
PSI/SI/PSIP/ARIB SI analysis and repetition rate graphing
Allows broadcasters to determine that the system and service
information is present and correct in the Transport Stream
"Green Stream" learning mode
Allows monitoring by exception and elimination of false alarms
Multiplex view
Allows an at-a-glance view of program utilization over an extended
period allowing the user to see if bandwidth spikes occurred
Unique 2-level alarms
Uniquely provides advanced warning of impending problems to avoid
customer complaints. Single-level alarming means the alert can only
be generated. With 2-level alarms, separate warning and failure
alarms are not possible
FlexVuPlus™
Uniquely presents simplified presentation of video quality and
diagnostic information
Filtered logs
Allows diagnostics to be performed at the TS, Program, or PID levels
to "zoom in" on problems quickly
Simultaneous connection of multiple remote users and Multi-sink SNMP
traps for Network Management Systems (NMS)
Provides early visibility of problems to key individuals throughout the
organization, supporting quicker notification and corrective action
Allows multiple users and/or NMS to access the MTM400A
simultaneously

Video and audio content monitoring to ensure QoE is maintained.
Digital TV Monitor — MTM400A
MTM400A Diagnostic Analysis Software Option
Trigger recording to be captured and rapidly analyzed in greater depth
using powerful offline analysis tools such as the Tektronix MTS4SA
software
Exception monitoring with simple, automated template generation from
reference streams. Template testing checks a number of key parameters
to ensure the Transport Stream has been constructed as 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
Advanced Timing Analysis including unique PTS-PCR graphs for
real-time buffer measurements. This provides indication of encoding and
multiplexing errors and in-depth PCR analysis; the resulting graphical
views enable timing and jitter measurements to ensure correct operation
of the network
Bit rate testing determines whether PIDs, programs, services, or
user-defined groups of PIDs are within user-definable limits, ensuring
correct multiplex operation. Tektronix proprietary PID variability test
gives indication of PID bit rate variation to assess effects of statistical
multiplexing
Advanced Timing Analysis including PTS-PCR for real-time buffer measurements to give
indication of encoding and multiplexing errors.
Comprehensive service logging enables verification of service level
agreements to ensure contractual obligations are met
The channel polling capability for the MTM400A, combined with RF
interfaces, allows up to 200 RF channels to be monitored in a repeating
cyclical 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

Technical Overview
SCTE-142 and A/78 monitoring modes classify five distinct levels of
importance
Transport Stream Off Air (TOA), Program Off Air (POA), Component
Missing (CM), Quality of Service (QoS), Technically Nonconformant
(TNC)
Enables filtering and display only of errors that require immediate
attention
Comprehensive TR 101 290 Priority 1, 2, and 3 MPEG measurements
Provides in-depth analysis of Transport Stream, syntax, timing, and
content to support root-cause analysis of system errors
Superior PCR measurements (PCR_OJ, DR, and FO)
PCR_OJ enable deterministic measurements on Transport Stream
and network induced jitter allowing such errors to be isolated
DR and FO measurements allow diagnosis of longer-term system
degradation
PSI/SI/PSIP/DC-II conformance and consistency checking
Closed Caption (EIA608/708 and SCTE20/21) and Regional Ratings
Descriptor (RRT) check ensures conformance to regulations
SI/PSI/PSIP testing ensures set-top box performance (channel
change, EPG, etc.) can be verified
SCTE 35 DPI monitoring
Allows analysis and diagnostics of "splice" advertising and other local
content
SCTE-142 and A/78 modes classify five distinct levels of importance.
