Meeting The Test & Measurement Challenge Cont.

a different way of

"

Balancing Act

74

Over at Nevion, meanwhile, Product
Manager Azzedine Abchir, sees
4K more as a change of scale
that simply requires evolution.
The challenge, he believes, lies
elsewhere. "OTT and second
screen approaches are more
revolutionary, however, as they
require a fresh approach in terms
of monitoring," he says.
"The distribution is done in an
entirely different way. There's
interaction between the viewer
and the provider which really
changes things. Traditionally we
had a unidirectional information
flow from the broadcaster or
service provider transmitting to
the homes, but now viewers want
to see content on demand so this
interaction requires a bi-directional
communication which has to be
monitored accordingly. The viewer
now controls the transmission, and
his ecosystem (client device and
broadband connection bandwidth)
define the transmission parameters,
so some new ones need to be
monitored and existing ones have
to be monitored differently in order
to ensure that the service meets the
viewer's expectations.
"OTT and second screen are
actually a different way of thinking
where we have to change our way
of thinking and create new rules,
directives, codes of practices

a n d re c o m m e n d a t i o n s o n
how to monitor."
Of course, it is hedging against
future development which is
exactly what initiatives such as the
increasingly infamous periodic table
of EBU Tech 3363 are all about; an
agreed set of terms and tests across
languages and broadcast cultures
that will guarantee consistency in
QC and QA. And Hamlet's Nunney
is one of those that sees it as a
good way of identifying the potential
issues and fixing them before they
leave the workflow system.
"The down side is the extra number
of tests that will need to be made
(Tech 3363 mentions 53 and a
further 100 tests being worked
on)," he says. "With all the different
formats and devices that people
are now watching the broadcasts
tests are being made overall and
not necessarily by device so
what looks great coming out the
workflow system "might not look
very good on a smartphone" - but
will it matter? Even professional
broadcasters who are replaying their
transmission using the on-demand
systems over the broadband to a
home PC are reducing the quality
of the programme so audio and
video errors are clearly visible - If
these professional companies are
not worried about the quality then
where do we go from here?"

Forward Paths

So, what progress will be made
along that path at NAB this
year? Where are we going in the
immediate future?
B r i d g e Te c h n o l o g i e s i s
showcasing its Objective QoE
system, which avoids the robotised
simulation of user experience in
favour of empirical signal analysis
to detect errors that affect QoE.
The VB288 is the window on this
process, with its web-based 'virtual
videowall' that allows QA staff to
see what the viewer is seeing.

DK Technologies' T7 Audio, Loudness & Logging System

"It's a rational approach to QoE,
without the historical baggage from
QoE's origins in telecoms testing,"
says Frostad.
DK is emphasising its work on
Loudness with its DK T7 Audio,
Loudness & Logging System,
while Hamlet is showing
new versions of
i t s Vi d S c o p e
software.
Nevion
is
shipping its NS4200
media monitoring probe,
a high density, flexible media
monitoring solution for IP/Ethernet,
DVB-S/S2 and DVB-ASI streams.
"The concept was announced at
IBC2013 but it is now shipping
and we've since added additional
functionality; it can now also monitor
satellite feeds and streams which
is a big step forward," says Abchir.
OmniTek, meanwhile, is targeting
4K. "Our new 4K Tool Box launching
at NAB is targeted at 4K/60 early
adopters, where the ability to
analyse the multiple streams that
comprise 4K resolution video is
required, coupled with the tools to
convert and generate 4K test signals
to exercise, e.g. manufacturers' own
products or integrators' systems,"
says the company's David Ackroyd.
Triveni is demonstrating the fifth
generation of its StreamScope realtime DTV transport stream analysis
and troubleshooting system and
GuideBuilder PSIP, SI, and mobile
ESG generator, as well as products
that support ATSC 2.0, ATSC 3.0,
and that all-important emerging
multiscreen viewing environment
for local television content.
Video Clarity is showcasing

Triveni Digital's
portable, tablet-based
MPEG analysis and monitoring tool,
StreamScope Portal

its reduced-reference operating
mode for its RTM solution, which
is intended for secondary content
distributors. When a content
originator sends a satellite feed to
secondary distributors, a device on
the content originator end sends
out a small amount of data via
the Internet about portions of the
source signal.
Secondary distributors may
subscribe to that data stream so
that when they receive a satellite
feed from the content originator,
their RTM unit will compare the
incoming video signal with the
Internet data about the original
source signal.
It's a neat system and one that
nicely illustrates some of the new
paths test and measurement needs
to be heading down if it is to keep
up with the challenge of maintaining
optimal picture quality across all
screens at all times.
