Cavena: Subtitling
And Transcoding
Subtitling is mainly used for two things; to make
foreign language material accessible, and to aid
hearing impaired people...

T

ranslation subtitling allows a
broadcaster to reach multiple
language audiences, which makes
it ideal for targeting multiple
language groups. The viewer can
select the language to receive.
For hearing impaired people,
subtitling allows them to follow,
and is a legal requirement in many
countries. And given, subtitling
follows the video to the pad and
the smartphone.
How does subtitling work?
Subtitling comprises of two stages
- preparation and transmission.
The preparation of the subtitle
files, along with the timecode
required to synchronise the
subtitle with the video, is done
ahead of transmission. These
are delivered to the transmission
site in a format defined by the
broadcaster, and stored until
needed for transmission.
Subtitle
transmission
is

an automated process. The
equipment interfaces to station
planning and automation systems
to receive programme and trigger
information. The transmission
units
then
synchronise
the
subtitles for playout using the
video playout timecode. Subtitles
are output in suitable formats for
the transmission platform.
Transcoding:
Transcoding of subtitles is the
process of reading subtitle data
from a signal or data stream and
convert those subtitles on the fly
to one or more other transmission
formats. In layman terms; what
comes in - goes out.
In Asia we see a growing need for
DVB in and DVB out, both as is or
with a short delay for censorship.

Subtitling is a legal requirement in many countries.

It is DVB Subtitling retime stamped
and output as DVB Subtitling.
Scaling from SD to HD DVB
Subtitles or vice-versa can take
place.
The Cavena transcode solution
is modular and flexible. Capacity is
dependent on input format being
an SDI signal or IP and number of
languages to be transcoded. The
start module being a 1RU solution,
based on an HP server, shipped
pre-configured and ready to go on
air. The Cavena transcode solution
can be standalone or automation
controlled. The Cavena transcode
solution can be upgraded to
cater for file-based play out or a

combination of transcode and file
based play out.
Trends in Subtitling:
The choice of more languages
anytime and anywhere includes
subtitles. We assist more and
more customers in transcoding,
for example DVB or teletext in
and DVB out. Temporary storage
by recording subtitles is also
possible, allowing editing and
censorship before the material is
re-transmitted.
We also assist with OTT
solutions, both integrating with
streaming vendors and standalone
solutions.
