NRK Invests in Leader T&M
for OB24 Expanding Trailer

Norwegian public broadcaster NRK has chosen Leader waveform monitors and rasterising test equipment
as the core reference instruments for its latest-generation mobile production trailer, OB24...

R

ecently completed by Lithuanian
system integration specialist
TVC (www.tvc.tv), the vehicle includes
seven Leader test instruments and an
LT4448 error-detecting automatic
channel switcher.
"At 13.6 metres long and weighing
26 tonnes, OB24 is one of the largest
vehicles in our fleet," comments Aras
Kriaučiūnas, Head of TVC's Projects
Management Group. "Equipped with
24 dedicated workplaces, it comprises
a camera control suite, a slow-motion
video effects facility, two production
galleries, an audio control suite, plus
an apparatus and server room. OB24
is a no-compromise vehicle designed
to handle simultaneous feeds from
28 cameras. Colour matching that
number of sources during a largescale OB requires very careful signal
monitoring. Four Leader ZEN-series
LV5350 portable 12G/3G/HD/SD-SDI
waveform monitors were chosen for
the camera control suite plus a ZENseries LV7300 rasterizer for the main
production gallery."

Leader ZEN-series LV5350 portable
12G/3G/HD/SD-SDI waveform monitor

"We have also integrated two LT4610
3G/HD/SD multi-format video sync
generators into the apparatus room
where they will be used to generate
reference sync, test patterns, logos,
safe-action and safe-title markers
as well as audio test tones. A Leader
LT4448
auto
changeover
unit
constantly monitors critical channels
during the production process and
either generates an alert if it detects
any error or, if desired, switches
automatically to a backup source.
Other key infrastructure provided
includes EVS slow motion effects,
Genelec loudspeakers, Grass Valley
(video router and multiviewer), Lawo
and Yamaha audio mixing, Riedel fibre
networking, Sony (cameras, video

NRK's OB24 can handle up
to 28 camera inputs

mixer and picture monitors),
Vislink wireless camera
links and Vizrt graphics."
"Leader test instruments
have become the preferred
choice for many OB fleet
operators and production facilities,"
adds Leader Europe Managing Director
Koichi Fukagawa. "Recent examples
include TVN's UE6 4K HDR OB truck,
Mediapro for its UHD coverage of
the UEFA Champions League Final
in Madrid and dock10 for its 4K/
UHD and HDR-capable grading and
finishing areas at MediaCityUK. Our
strategy is to provide all the test and
measurement capabilities required
to meet current broadcast media
standards and, at least as options,
the features needed to ensure new
creative content is as future-proof as
possible."
Test Instruments
Leader's
LV5350
waveform
monitor and LV7300 rasterizer
incorporate a very wide range
of SDI signal testing features.
These include engineering-related
reference tools such as test pattern
generation, closed-caption monitoring,
CIE colour chart, high dynamic
range measurement, focus assist,
customisable screen layout, tally
interface, 4K/UHD operation and
12G-SDI interfaces. The LV5350 and
LV7300 also incorporate Leader's
intuitive CINEZONE and CINELITE
which are familiar to many camera
crews, editors and colourists. A focus
detection algorithm enables
the two instruments to
sense edges across a
very wide range of image
contrast levels.
The LT4610 is a 1U x 400
mm front-to-back 3G/HD/SD

ZEN-series LV7300 rasterizer

multi-format video sync generator.
Test patterns available from the
LT4610 include 100% and 75% colour
bars, multi-format colour bars and
SDI check fields with user-selectable
scrolling in eight combinations of up/
down/left/right. Scrolling speed is
user adjustable from 1 to 256 pixels or
lines. Y/G, Cb/B, Cr/R components can
be turned on or off independently for
each output channel. The LT4610 has a
genlock input and can be synchronized
with NTSC/PAL black burst or HD trilevel sync signals. Standard support
for SNMP via Ethernet makes it easy
to integrate the LT4610 into a network
environment. Alarms are generated
with SNMP and displayed on the front
panel when errors do occur.
Designed for use standalone or in
combination with the LT4610, the
LT4448 is a changeover unit that
automatically switches from the
primary signal to the backup signal
when problems are detected in the
primary signal. A single LT4448
provides 11 channels which can receive
LTC, SDI, NTSC/PAL black burst, HD
tri-level sync, AES/EBU digital audio,
and word-clock signals. SDI signals are
switched with relays. All other signals
are switched with electronic switches.
Redundant power supplies are
included.

TVC Systems Integration
With more than 150 OB vehicle
projects and 60 studio installations
completed since its establishment
in 1996, TVC is one of Europe's
fastest growing independent systems
integrators. Among regular projects
are systems design, equipment supply
and integration of television and radio
studios, master control rooms,
playout systems, news rooms
and archives. A special focus
is paid to outside broadcast
van projects with a track
record of over hundred
OB vans supplied to clients
across Middle East, Africa, Asia and
Europe.
