Comprehensive
Monitoring for
Distribution Networks
As technology is rapidly evolving to allow users to view content when and where
they want, full-time monitoring is paramount...

E

nsuring that media content is
delivered intact to viewers has
become much more challenging
over the past few decades, as new
distribution technologies and partners
have been welcomed enthusiastically
by end-users. Not only do government
regulations on loudness and captioning
need to be observed, but also the
potential impacts of signal quality on
viewer engagement level and audience
measurements can have a critical
impact on a broadcaster's bottom
line. Ideally, all aspects of every
media stream type must be monitored
continuously, on every channel, and
across every viewer device type.
Comprehensive
end-to-end
monitoring of distribution networks
across multiple technologies is now
possible using the new Distribution
Monitoring solution within Volicon's
Media Intelligence Platform. Using this
system, actual customer experiences
can be measured and recorded for
a complete channel lineup across a
full distribution system. The rich data
gathered by this system can be used
for many purposes, including input
signal verification, monitoring internal
systems,
validating
downstream
networks/distribution
channels,
and supporting end-to-end system
diagnostics and troubleshooting.
Delivering high-quality, engaging
programming is the best way to
ensure a vibrant audience for any type
of media content, and this applies not
only to scripts and acting, but also
to the watchability of the delivered
programming. Even the most engaging
drama will fail to win an audience if
viewers are unable to comfortably
see and hear the content using the
delivery channel and device of their
choice. Achieving a consistently
high level of performance requires
continuous monitoring, so that
problems can be quickly detected and
addressed, and long-term trends can

be analysed to detect and resolve
degradations before they can affect
viewers.
Full path monitoring is the most
effective means to ensure that
video signals are being delivered as
intended. By capturing actual video
signals and making measurements at
as many locations as possible along
the path from source to viewer, the
greatest number of problems and
trends can be detected. In practical
terms, this means monitoring the
signal as close to the original source
as possible, at multiple points along
the transmission path (generally
whenever significant transformations
are made to the signals), and then as
far out towards the ultimate viewer as
possible. In some cases, when the feed
is being delivered to the consumer
by means of a distribution partner,
this can mean monitoring the signals
both before and after they have been
transmitted through a network that
is the property (and responsibility)
or another entity, such as an MVPD
(multichannel video programming
distributor). This is good practice
because it enables a programmer to
actually quantify signal performance
when it reaches the viewer, but can be
frustrating if problems are uncovered
that are outside of an organisation's
area of authority to correct them.
Nevertheless,
knowing
about
problems is better than not knowing
and suffering declines in viewership
due to poor-quality video delivery.
When monitoring is performed, it
is important to capture and measure
the signals from an actual customer's
perspective. This is where
measuring QoE (Quality
of Experience) is so
important
because
it reflects the quality of a
video signal based on what a viewer
actually sees in the video, rather than
measuring the QoS (Quality of Service)

of the network that delivers the
video. To understand the difference,
it is important to realise that a signal
can have a high QoE score, even if it
has been delivered over a low QoS
network, provided that the buffers
used are large enough to handle
any packet delay variation, and that
the FEC (forward error correction)
system is robust enough to handle
any lost packets. Conversely, a high
QoS signal can have a poor QoE, which
could happen when a signal being
delivered over a perfect network has
the wrong language audio track, or
has incorrectly set metadata for image
size or loudness.
Long-term trend analysis is also
an ideal way to detect and capture
intermittent problems, which, by their
very nature, are not easy to measure
and diagnose. Recording a continuous
stream at multiple points through a
network generates a rich dataset that
can be analysed in real time for live
monitoring, or stored for subsequent
review.
Comparing
data
sets
generated along
a path allows
patterns to be
uncovered and

Volicon's Monitor
application allows broadcasters
to monitor from anywhere, anytime

correlations discovered. Recorded
sequences also permit comparisons to
be made between current behaviours
and ones that have been previously
observed to discern if changes have
occurred.
Flexibility in measurement and
recording is also a key aspect of
system usability. The goal is to be
able to monitor any feed, at any
point along a path, any network
output, using any device available
to the viewer. Accomplishing this
goal requires a number of different
hardware and software options that
can be configured to accommodate
the wide range of different
architectures that are being used in
video production and distribution
networks today. Systems need to work
with compressed and uncompressed
video and audio, encrypted and nonencrypted streams, fixed and mobile
user devices, and be able to interface
with many different transmission
technologies including cable, satellite,
broadcast, IPTV, OTT, and private
media networks.
