Telestream Closed
Caption Inserter
& Multiscreen Live
Streaming Solution

A

t NAB 2018, Telestream will
introduce a unique 'one-boxsolution' for closed caption encoding to
multiple live streams.
Sophisticated
608/708
caption
insertion capability is part of the latest
version of Lightspeed Live Stream,
Telestream's multiscreen live encoding
and packaging at scale solution for
broadcasters, content aggregators and
live event production companies.
From national broadcasters to college
sports, houses of worship, live event
producers and even the military,
the broadest range of organisations
need live captioning. As live video
streaming over IP networks continues
to grow exponentially, the need for
live closed captions within multiscreen
applications is becoming critical. In
response, Telestream's new integrated
live caption encoding solution is
now part of Lightspeed Live Stream,
helping avoid the cost and complexity
of going to baseband when inserting
digital captions.
Today, virtually all IP caption insertion
systems are Cloud-based, requiring
content to be moved first to the Cloud,
there captioned, then re-encoded
and re-streamed for delivery. This
introduces significant opportunity
for human and mechanical error,
ultimately impacting the quality of the
final content. In contrast, Telestream's
live
captioning
solution
with
Lightspeed Live Stream eliminates
restreaming, instead encoding the live
captions within the original stream and
ensuring the best possible quality.
And unlike expensive traditional onechannel baseband caption hardware,
Telestream has used its industry-

leading experience to develop a single
1RU enclosure that encodes captions
to multiple live video streams, saving
space and claiming to save between
US$7K to US$10K per channel. The
system's scalability offers on-demand
caption insertion over as many
streams as needed. Lightspeed Live
Stream uses standard captioning
protocols to receive caption data, so
existing third-party court reporting
software can connect to Lightspeed
Live Stream via IP, making the system
truly 'plug and play'.
"Whether its commercial broadcaster
streaming or live captions for
Facebook, YouTube or any other
streaming
platform,
we
have
developed functionality in Lightspeed
Live Stream that absolutely simplifies
live stream captioning," said Scott
Murray, VP Product Management at
Telestream. "Uniquely, our solution
involves no re-encoding or restreaming so there is zero possibility
of blips and glitches being introduced
into the streamed content."
In addition to the new live captioning
capabilities, users benefit from a
true enterprise-class live streaming,
encoding and packaging system.
For multiscreen live encoding and
packaging at scale, Lightspeed Live
Stream is Telestream's premiere live
encoder for broadcasters and content
aggregators. With this advanced
solution, users can add time delay
to the stream for synchronisation
purposes. In addition, they can use
Lightspeed Live Stream to route
captured recordings to Telestream's
Vantage Media Processing Platform for
further enhancement.
