SailTracks Selects AVIWEST
to Broadcast Live
S

ailTracks, a German video
producer specialising in sailing
competitions, deployed AVIWEST
PRO3 bonded cellular transmitters
and StreamHub transceiver for live
coverage of world-renowned sailing
races, such as the Medal Races at
the 2020 Hempel World Cup Series in
Enoshima, Japan.
SailTracks streams the races directly
onto Facebook and YouTube, providing
all followers with real-time results
and insights. Compact and robust, the
PRO3 Series has been directly installed
aboard SailTracks' vessels, which track
sailors closely during the competition.
"We were very impressed by the
AVIWEST units' performance reach.
The PRO3 allows us to go live in the
open sea and stream high-quality
videos, bringing the action to fans,"
said Marcus Baur, Managing Director
of SailTracks. "We've tested several
providers, and only AVIWEST could
handle tough weather conditions - the
temperature, humidity, and waves

- while offering us the requested
quality."
Using the PRO3 Series, which
implements the Emmy Awardwinning Safe Streams Transport
protocol, SailTracks
can
seamlessly
stream
live
HD
sailing races and
store and forward
recorded
content
even in the midst
of
unpredictable
and
unmanaged
network conditions.
Moreover, the AVIWEST PRO3 can
synchronously backhaul multiple live
feeds with perfect genlock and lip sync
for multicamera, remote, and at-home
productions.
With up to 12 3G/4G/5G-compliant
network connections and Wi-Fi
modems with patented high-efficiency
custom antenna arrays, the PRO3
Series makes it easy for the German
video producer to conduct live

interviews
and
sailing events with
flawless premium HEVC encoding.
Another key benefit of the PRO3 Series
is its SIP-based intercom to simplify
communications between SailTracks'
master control room and remote
transmitter operators aboard ships.
"We provide SailTracks' team with
an easy-to-deploy and easy-to-use
live transmission solution that is
efficiently integrated into its existing
video production workflow," said

Alexandre Augereau, Sales Manager at
AVIWEST. "Moreover, by detecting and
bonding together multiple IP network
interfaces, our transmitters assure
the delivery of live transmissions over
internet networks, allowing highquality streams from any location, even
in the open sea."
SailTracks is the live broadcaster
for the Hempel World Cup Series,
the German Sailing League and the
international
Sailing
Champions
League.

Bogotá TV Station Citytv Automates
Live Closed Captioning
E

NCO's enCaption4 automated
closed captioning system has been
deployed by Colombian TV channel
Citytv.
The TV station serving the capital city
region of Bogota has since increased
speed and accuracy while reporting a
reduction in captioning costs of 75%.
Citytv, owned by media company
Casa Editorial El Tiempo, licenses
the Citytv brand from Canadian
communications company Rogers
Media. The station, which broadcasts
on UHF channel 21, follows a mandate
that requires Colombian over-the-air
TV stations to provide closed captions
in three-quarters of their programmes
between 6am and midnight. Citytv
captions its daily news programme,
Citynoticias, along with other popular
shows such as Arriba Bogotá and
Bravissimo.
"We
have
closely
monitored
enCaption4's
development,
and
it clearly has reached the level of
accuracy we required," said Walter

Gomez Zuluaga, Engineering and
Operations Manager, Citytv. "We now
have a solution that fully automates the
captioning process, better serves our
hard of hearing viewers, and ensure we
meet all regulatory obligations."
The speed by which enCaption4
generates closed captions, especially
compared to the manual "listen and
talk" speech recognition system that
it replaced, was a key factor in Citytv's
decision. Building on ENCO's patented
automated
captioning
approach,
enCaption4 combines machine learning
with a neural-network speech-to-text
engine to deliver exceptional accuracy
with extremely low latency.
"We typically encountered a 10 to
15 second delay between the spoken
word and its on-screen caption with
our previous system," said Gomez.
"enCaption4 has reduced this gap to
just four seconds while maintaining a
high degree of accuracy. Furthermore,
the 75% reduction in operating costs
will deliver an estimated return on

investment of roughly 24
months."
While the system can
be deployed on premises
or in the cloud, Citytv
preferred to install it
locally in its broadcast
master control room.
There, it's configured
to receive a programme video signal
with embedded audio. The captions
generated by enCaption4 travel
over IP to an Evertz encoder, which
embeds them into the live broadcast
video.
Citytv also interfaces enCaption with
its MediaCentral (iNews) newsroom
computer system (NRCS) to familiarise
it with specific words that it will
interpret into captions. Using MOS
standard protocol, enCaption4 can
access news scripts and rundowns
from any NRCS and learn correct
vocabulary, spellings, names, places,
and other special content that will
be mentioned in the local newscasts.

ENCO's enCaption4

It retains these terms in its everexpanding
internal
dictionary,
becoming more valuable to the user
over time.
Continual product development has
also resulted in enCaption4's ability to
distinguish between multiple people
speaking.
enCaption4 today supports more
than 30 languages with accurate
spelling,
capitalization,
and
punctuation to strengthen caption
quality.
