The MTM400A provides a complete solution for real-time transmission
monitoring of MPEG transport streams over RF, IP, and ASI interfaces.
It combines powerful confidence monitoring capability with deep diagnostic
measurements within a single integrated solution. This supports Broadcasters,
Cable, Satellite and Telecommunication operators to deliver superior
Quality of Service (QoS) levels with reduced operational expenditure
Flexible and Upgradeable
The MTM400A 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
- 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 enables
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
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.
The MTM400A transport stream monitor enhances video network QoS with:
- MTM400A'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
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.
MTM400A 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 MTM400A
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-packetised MPEG Stream
for analysis and recording. Input Source on the Gigabit Ethernet
Card can be switched between Ethernet Electrical (RJ45), Ethernet Optical
(SFP at Multi Mode 850nm, Single Mode at 1310nm, Single Mode at 1550nm)

Cable Headend
Cable companies need to verify content accuracy at multiple, unmanned
headend sites as operations are centralized. Budgets are tight and resources
are limited.
- The MTM400A is a cost effective solution which can be used
for unattended operation for unmanned regional headends
- Network monitoring units linked to central operations center
reduces manpower requirements
- Comprehensive coverage of QAM Annex A/B/C RF interfaces
allows cost-effective multi-channel, multi-layer monitoring
- RF interfaces allow cost effective scanning of all channels/multiplexes
on a cable
- Selection of PLL and AFC characteristics of the QAM interface
enables constellation analysis on signals that are too poor
for normal operation
|

QAM Signal Monitoring
|
Terrestrial DistributionTerrestrial broadcasters need to verify
the accuracy of content at unmanned transmitter sites. They need
to check for errors, troubleshoot problems and capture errors for offline
investigation.
- The MTM400A is designed of 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 8-VSB RF terrestrial interfaces allow monitoring at
the transmitter site or remote off air monitoring

DTH or Network Operator Satellite Uplink Monitoring
DTH networks are characterized by large numbers of channels monitored
by limited numbers of 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. Operators therefore need to monitor both
before and after modulation
- The cost-effective MTM400A 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
IPTV
IPTV presents new monitoring challenges for video test. MTM400A
offers broad IP monitoring capability to show multi session IP traffic
display with IP packet errors for all sessions on the link backed up
with deep MPEG measurement and recording capability. Strong linkage
between IP and MPEG layer errors in the MTM400A integrated error log
show the relationship between IP and TS errors.
Edge Device Monitoring
Edge device monitoring is becoming key in modern hybrid networks.
MTM400A addresses this need with ASI to IP or RF measurement interfaces:
- ASI to RF
- IP to RF (requires two MTM400A Units)
- IP to ASI

personal computer.
The interface initially displays a main status view with menu buttons
to access either stream status summary or device status summary.
The stream status summary provides an overview of the health and contents
of the stream with the ability to access all available tests and measurements
licensed for the unit. Summaries can be focused on Program content,
SI content, or on all PIDs
