viewer experience, especially
in
live production. HDR provides
substantially
brighter highlights,
deeper shadow details, brilliant
colors, and
remarkable picture
quality. But since not every device
today
supports
HDR, there are
multiple challenges to implementing
a seamless
end-to-end workflow
that is compatible with both HDR
and legacy Standard Dynamic Range
(SDR) content at the production side
and delivers it
efficiently
to both
legacy and new playout devices on
the receiving side - without image
quality compromises.
Producing in HDR for live
programming would be the ideal
scenario but
requires
legacy SDR
sources be converted to HDR. This
way, the whole production can
be done in HDR. Bridging the
SDR-HDR gap has been a focus for
Cobalt
Digital, and working with
technology partner Advanced HDR
by Technicolor, the Company has
developed an innovative workflow
to deliver a mix of SDR and HDR
sources in a seamless, dynamic, and
automated process using Advanced
HDR by Technicolor Intelligent Tone
Management (ITM).
The innovative workflow leverages
Cobalt's 9904-UDX-4K
for
processing card
SDR-to-HDR
conversion, providing an elegant and
easy solution to allow legacy SDR
sources to be ingested into an HDR
production environment and turn SDR
into HDR using a dynamic algorithm
that optimizes the output based on
the content.
