SDI-KVM converters automatically
detect the input video format and
instantly
change
between
SDI
broadcast formats to high-definition
DVI, HDMI, or DisplayPort computer
video formats.
LiveU extended its Solo product line
of professional-grade wireless video
encoders to accommodate the growing
needs of online content creators
streaming to social media and other
online destinations. The Solo HDMI
encoder offers a lower priced option
for portable and reliable live online
coverage. Solo Studio features cloud
graphics for branding content. Solo
app (for Apple iOS) enables users to
send live content over cellular and
Wi-Fi connections for more reliable
streaming than smartphones.
Miller Camera Support Equipment
showed its ArrowFX 7 fluid head which

Extended: LiveU Solo range

has magnetic encoders monitoring and
communicating the head's position. An
interface box connects with graphics
systems from companies such as Vizrt
and Orad. This provides real-time pan,
tilt, zoom and focus data, as well as
lens geometry information.
Nevion's Virtuoso is designed
for use in IP-based live production
environments where the distinction
between local and wide area networks
is becoming blurred. The latest
Virtuoso soft-ware update offers
bi-directional JPEG2000 encoding/
decoding
support
for
4K/UHD
(broadcast), 2K/4K (cinema), slowmotion and stereoscopic 3D for HD and
UHD. It also includes an alarm-based
input-switching capability which allows
automatic switching between multiple
SDI and SMPTE 2022-6 sources based
on the detection of specific conditions
such as black frame, freeze frame
or audio silence. The most recent
Virtuoso software update adds
SMPTE 2110-30 audio embedding/deembedding, with audio shuffling and
delay handling.
Tektronix' TekMOS is a fully
automated single-ended mean opinion

picture quality score evaluation
system. It uses machine-learning
techniques to evaluate picture quality
and identify distortions based on a
set of subjectively graded images.
It is designed to provides objective
measurement of picture quality so
broadcasters can grade picture quality
through their broadcast chain.
Telestream's Timed Text Speech is
a file-based auto-transcription service
for subtitling and captioning workflows
with MacCaption and CaptionMaker.
The latest version enables users to
modify transcripts directly in the cloud
from a web browser while the speech
engine continues to process the rest of
the video programme.
TSL Products' FlashBoard is a new
screen-based information distribution
and display system. Integrating with
TallyMan, third party control systems
or capable of independent operation,
FlashBoard drives multiple displays,
each with a unique combination of
data, clocks and timers, on-air and cue
lights and production details. Screens
can be configured quickly using the
drag and drop functionality in the
TallyMan virtual panel software for

display in monitor walls or distributed
wirelessly to tablets.
TVU Networks' TVU RPS allows
broadcasters to use their existing
studio control room infrastructure to
deliver frame accurate, genlocked and
synchronised multi-camera remote
production. A web interface is used
for monitoring and controlling all
aspects of the transmission, including
real-time previews of all channels,
current bit-rate and latency. Also
demonstrated was the TVU One live
mobile IP newsgathering transmitter
with integrated HEVC compression.
Designed to deliver HD quality video
with half-second latency at 3Mbps, it
is available with embedded modems
and can transmit simultaneously over
cellular, microwave, satellite, BGAN,
WiFi and Ethernet delivery channels.
Vitec's MGW Vision is a 1RU
HEVC/H.265
encoder
supporting
streaming of single UHD or four
HD HEVC channels ingested from
four 3G-SDI inputs. It can also store
encoded content while streaming onto
the network.

Bluebell Throwdown Multiplexer
12G-SDI Over Single Cable
By Paul McCann, Managing Director,
Bluebell Opticom

A

s UHDTV takes hold, singlecable transport of 4K signals is
becoming more and more imperative.
That's why Bluebell has put
considerable effort into building such
a solution: the BN390 standalone
interface supporting 4K/UHDTV in
broadcast studios and OB applications,
especially sport. With the BN390
multiplexer, broadcasters can avoid
using quad HD links, which are
cumbersome and time-consuming to
rig and install, in favour of sending all
signals on a single coax or fibre
cable. There are few if any other
products like the BN390 on the
market today.
There are two BN390 modules - a
multiplexer and a demultiplexer. An IN
and an OUT. That's it. However, despite
their simplicity, the BN390 units are

highly sophisticated configurable
tools for conversion between all of the
various formats of 4K UHD.
Because 12G-SDI doesn't travel far
on copper, these units come with
optical ports as standard. The factory
default is set to convert four 3G-SDI
signals on four BNC connectors to
12G-SDI on a single BNC and fibre optic
output. Beyond the default, a slew of
configurables includes HD-SDI, 6G-SDI,
dual link, and two identical 12G-SDI
images.

BN390
mutiplexer

Besides supporting SNMP
access, each BN390 unit
serves its own web page
for management, setup,
and configuration. An RJ45
port means the module can be
connected directly to a laptop or
hung on a network. The latest version
maps the existing control software to
Bluebell's emerging GUI technology
built for simple hardware control
during remote production.
The BN390 is small enough to be
strapped to the side of a camera. Most
4K cameras present their UHD signals
across four BNC connectors, creating a
headache for the operator, who must
manage four coaxial cables on the floor
out the back of the camera. Using the
BN390 alleviates that problem because
operators need only deal with a
single fibre optic cable or a single
coax - making setup tidy and less
time-consuming.
Besides studio and OB applications,

BN390
demultiplexer

the BN390 has also been used in 4K
edit suites. Most post houses already
have fibre installed, so jumping on
to their in-house networks is the
perfect way to move content between
processes. For example, converting
to fibre has proven to be a very neat
solution for moving rushes from one
suite to another.
In short, the BN390 is a small-formfactor, cost-effective, super-efficient,
agile, easy-to-operate multiplexer
product that slots into a 4K UHD
workflow beautifully. Simply plug it
in, configure it, and go. Unique in its
performance capability and signal
integrity, the BN390 saves time and
labour - and therefore money - for the
operator.
