Subtitling Made Easier with OCR
Real-Time Bitmap Conversion
With competition increasing in the online TV space, the value of attractive
content is higher than ever...

C

ontent needs to not only be accessible at
the right time and on the right screen, but
also in the right language.
With a population of more than four billion
people speaking about 2,300 languages,
translation is not just necessary, but critical
in Asia. However, several factors make this
problem harder than it might seem at first.
We've seen the industry adopt several
alternative subtitling standards, but many
subtitling solutions cannot handle Asian script
at all. For Asian linear TV, there are mainly two

technologies used: burned-in or DVB.
Burned-in is also referred to as 'in-vision',
which means that the text is part of the
picture. In some countries, there are two
different languages presented on top of each
other. There can be up to four rows of text at
the bottom of the screen, which takes up a lot
of space.
DVB, also known as DVB bitmap subtitling,
generates pictures of the subtitles at the
broadcast center which are then multiplexed
into the transport stream and distributed to
the end viewer. This supports any language,

character set and many subtitle tracks, so the
end viewer can select what subtitle language
to display. These image-based subtitles work
well for linear TV and IPTV using conventional
set top boxes.
However, OTT streaming formats generally
don't support bitmap-based subtitles. In fact,
HLS and Smooth streaming formats don't
support it at all. And even though DASH has
some support for bitmap subtitles, it doesn't
behave well with a variety of aspect ratios.
This means that image-based subtitles need
to be converted to text on-the-fly, so they can

render well on the multiple screens the OTT
streaming service supports.
At BroadcastAsia, Edgeware is presenting
its new cloud-based solution which
tackles this problem. Edgeware's subtitling
technology is developed by Cavena Image
Products, which was acquired by Edgeware
earlier this year. Cavena OTT subtitling uses
Optical Character Recognition to convert
bitmap subtitles to text in real-time. This
is integrated with Edgeware's TV Content
Capture, which takes in the text and segments
it together with the audio and video into a
synchronized stream. It is then repackaged
on-the-fly into the required format (for
example, HLS or DASH).
OCR subtitling is now available as part
of the Edgeware Cloud Service that will be
presented on stand in the TV Everywhere
Zone.
