The Evolution from
Compliance Logging
Broadcast logging has evolved from a narrow compliance role to a much broader
range of monitoring and revenue generating capabilities...

T

he advances made in just over
a decade have turned loggers
into highly diverse appliances for
broadcasters, covering far more
territory than their original mandate.
The next generation of logging
applications needs to be ready to cater
to an even wider range of applications
in the broadcast chain.
Early Advances in Digital Logging
Media recorded from baseband
sources is essentially encoded, proxy
size media. Although this meets the
requirements of content compliance
and covers some quality assurance,
it does not offer an easy way to
enhance quality of service (QoS) of
the actual transmission, or to access
the metadata available in the original
transport stream (TS). The cost of
storage used to be relatively high and
retaining 90 or more days' of native
transmission quality video and audio,
as required by regulators, was not
cost effective. In addition, network
connections were not always fast
enough for larger files sizes and much
higher bandwidth was required to
stream native MPEG media. Moore's
Law over time delivered faster
hardware, larger capacity servers
and storage, and faster networking
infrastructure.
That
significantly
opened up new opportunities for
broadcasters.
Transport Streams as the Source
Leading the way to the dawn of the
second generation of digital loggers,
Mediaproxy's foresight and broadcast
experience brought recording from
transport stream sources to traditional
compliance logging as an industry first
in 2008. This allowed broadcasters to
monitor, review, and analyse native
transmissions, and to store them on

the same cost-effective local storage
array in parallel with their proxy
media. Engineers could now review
native transmissions from the past few
days to complete technical forensics
to improve their services. QoS
monitoring, whether live or offline,
provided seamless review from local
and remote locations. This technically
provides customers with a path to true
compliance, since baseband is not the
transmission format. Also being able
to perform ASI play out for sections of
interest directly from an intuitive use
web interface has given engineers a
powerful option to replay transmission
in its original format, on demand.
Metadata, Search, and Analysis
TS logging enables simultaneous
recording and streaming of up to
hundreds of ASI- or IP-based channels.
Metadata, such as closed captioning
(EIA608/CEA708/OP42/OP47),
DVB
subtitles, multiple language tracks
and, EGP and PSIP information,
is available for advanced search,
live detection, and after the fact
exports via extensive burn-in and
transcoding features. Adding to the
Swiss army knife of logging, extensive
transport stream analysis, digital
program insertion detection (SCTE35/104). Fingerprinting engines to
provide random content matching
(fingerprinting) and ad verification also
made their way into the ever growing
portfolio of the once humble VHS
replacement.

Green is Good
Energy consumption and form
factor is another important factor
for broadcasters. Mediaproxy heavily
invests in hardware R&D to offer
increased channel density, storage
capacity, and processing power,
whilst maintaining
the highest level
of redundancy and
reliability. Hardware
components
are
carefully chosen, and
undergo
rigorous
test cycles to support
24/7 environments.
offers
The sole focus at Mediaproxy is to deliver on high expectations Mediaproxy

Mediaproxy's flexible LogServer platform is intrinsically built to evolve with the
changing needs of broadcasters

the most power-efficient and costeffective enterprise grade SDI and
IP platforms in a 2RU form factor,
allowing for recording up to 60 IP
channels, and up to 21 SDI channels of
logging.
The Real Cost of Compliance
Today, broadcasters have to deal
with ever increasing scrutiny by
their respective regulatory bodies
and compliance agencies. Changes
are introduced at a faster pace
and sometimes suddenly to keep
up with, in turn, ever increasing
scrutiny by audiences around the
world, extending to pressures via
social media platforms. Making an
investment in the right platform
has become more critical than ever.
Considering the availability of a
broad range of products promising
to provide a suitable solution, savvy
customers are looking beyond
marketing hype and low price points
to find the most experienced partner,
who can provide a truly sustainable
solution. It's paramount to team up
with a technology partner that can
react to regulatory changes quickly,
and deliver both robust software
and reliable hardware to span the
many years of 24/7 operation of the
system, to ensure the investment
is protected. Having pioneered in
this field of broadcast for over 14
years, and substantially invested in
cutting edge software R&D to ensure
tomorrow's complex requirements
are sustainable, Mediaproxy's flexible
LogServer platform is intrinsically built

to evolve with the changing needs of
broadcasters.
Logging is often seen as one of
the less important parts of larger
scale projects or general compliance
purposes. This is certainly true from
the standpoint of weighing up cost
and performance of technology
that provides 'to-air' versus 'off-air'
services. The reality is that the modern
compliance logger will be accessible by
a wide range of users across various
departments beyond engineering,
including sales, marketing, master
control, company executives, etc.
The exposure and consequent
reliance on such a product for several
applications within the station, beyond
the regulatory requirement, calls for
a decision that takes more than the
obvious factors into consideration.
Making an investment in a product
that on the surface provides the
obvious
features
required,
or
potentially the cheapest price point,
may not always be the best decision.
Taking into consideration the total cost
of ownership requires a more rigorous
due diligence process to ensure the
chosen partner practises sustainable
software product development, and
provides the best value solution for
the future. Delivering on these high
expectations is Mediaproxy's sole
focus. Its constantly growing team of
highly skilled software and broadcast
engineers ensures that the LogServer
core engine is built on tomorrow's
development frameworks, to provide
the most reliable and flexible
technology available.
