Compliance Logging Served
Up With Jünger Audio J*AM
W

ith
loudness-based
normalisation now adopted
by many countries, broadcasters are
increasingly being asked to measure
loudness values to ensure compliance
with
local
regulations.
These
measurements need to be backed up
with a log of historical values.
In response to this need, German
manufacturer Jünger Audio has
created the J*AM Application Manager,
a software package that runs on
Windows and allows for real-time
monitoring and measurement of
loudness and true peak input and/or
output values.
"Although we are best known
for our extensive line-up of realtime hardware based digital audio
processors, we also offer compliance
logging software tools such as J*AM
that are designed to make life easier
for broadcasters," says Peter Poers,
Business Development Manager at
Jünger Audio. "When coupled with
an optional Loudness Logger license,

J*AM allows broadcasters to store all
measured values in log files for future
recall."
Available as a free of charge
download, Jünger Audio's J*AM
software can be installed anywhere
on a broadcaster's network and can
communicate
simultaneously
via
Ethernet with multiple Jünger Audio
devices. An intuitive user interface
makes set-up and configuration very
straightforward and all currently
connected devices are displayed in the
main control window. An on-screen
level meter displays bar graphs of
peak input and output for both stereo
or 5.1 channel processors, along with
an indication of the gain changing
activity of the leveller, dynamics and
limiter sections. In addition, numerical
readouts display both short term and
integrated (LUFS or LKFS depending
on the selected standard) loudness
input and output values.
An array of extra features and
functionality can be accessed by

broadcasters
who
choose to access the
Loudness
Logger
license
option.
Installed via a USB
dongle,
Loudness
Logger opens a
separate
window
that displays a live
plot of short-term
loudness and true
peak
input/output
values. A loudness
distribution
graph
also
shows
the
evolution of pre-treated compared to
post-treated signals over time.
The license also allows for logging
of measured data from all channels
of each connected device to a folder
location anywhere on the network.
The frequency and duration of the
log files can be easily customised.
The log files are stored in csv format
but to aid future interpretation, a
comprehensive log file analyser tool is

Edgeware Explore Case
For Dedicated CDNs

A

t IBC2017, Edgeware, the
pioneer of TV CDN technology
will showcase its latest research into
when content owners and online TV
distributors should consider ceasing
CDN rental and instead build their own
delivery infrastructure.
"We understand that private TV
CDNs aren't the right approach for
everyone but more and more giants
in the content delivery industry are
recognising that it's the right option
for them," says Edgeware CEO Joachim
Roos. "We work with customers
that have turned to private
networks so they can take
control of their content
and deliver high-quality TV
services while benefitting from
a cost-effective solution."
To demonstrate when a
self-built solution is right for a
content distributor Edgeware
commissioned Frost & Sullivan
to create a whitepaper which

lays out a set of criteria which helps
operators decide if a self-built network
is for them. Building Your Own CDN
For Video Delivery: Why, When, And
How, explains how many regular users
a service needs to have, where those
users need to be based and for how
long they watch a service for as the
basis for the answer to the build vs
buy question. The Frost and Sullivan
whitepaper states that "as content
volumes grow, the cost of owning and
operating a private CDN begins to look
more attractive than pay-as-you-go."

Avni Rambhia, Principal Analyst
at Frost & Sullivan says: "The
unicast nature of on-demand TVEverywhere strains infrastructure. As
OTT consumption grows, operators
are aggressively seeking options
to optimise use of their existing
broadband infrastructure to maximise
delivery capacity."
To back up the paper's criteria,
Edgeware has also built a business
case tool based on real customer
experience which shows the economic
tipping point where building your

included. This opens the selected log
file and rebuilds the stored data into
its original graphical plot format. The
date and time stamp makes it simple
to look back at a specific point, and a
zoom function allows precise analysis.
A log file comparator can display two
plots simultaneously for side-by-side
comparisons.
J*AM supports all current broadcast
audio loudness standards.

own TV CDN becomes beneficial. This
balances up the cost of equipment,
software licenses, backhaul capacity,
rack-space, power and operational
staff vs the price of renting a CDN as a
service.
"There are many different metrics
that determine the business case
for and against a CDN service. These
culminate in a tipping point where
content owners should deliver content
through their own network," explains
Edgeware Chief Marketing Officer
Richard Brandon. "For TV operators
who are serving audiences in close
geographical areas and have a growing
number of viewers regularly tuning
in, then a self-built TV CDN will pay
for itself within months while also
delivering services with no buffering
delays or glitches."
The trend towards self-built
TV CDNs is reflected in Edgeware's own business - after
floating on the NASDAQ stock
exchange in December 2016,
the company posted an endof-year annual increase in
sales of 23.9%.
