A great question and it's kind of the
big buzzword right now.
HDR it's a way of presenting video with
more luminance, more contrast and more
colour and we're used to seeing on
standard TVs today. It's very demonstrative,
it looks great, it's even more
eye-popping than just seeing standard 4K
content. You can have 4K UHD content or
you can have 4K UHD content with HDR on
it and it's just an enhancement to that
4K picture. Dynamic range is important
because to the human eye were most
sensitive to dynamic range. Which is our
contrast - it's a difference between the
peak white light and that darkest dark
that your display can create. It's a
dynamic range and the greater that
dynamic range, the more steps we get in
between it and the more exciting it
looks to the eye when we do that contact.
sSo with HDR displays and all the new
features we have in HDR, we not only have
our colour palette - but we have a much
wider colour palette. And that palettes
not flat anymore, you think of it as
volume of colour because of all the
luminance we get out of this
HDR TVs. We have colour that is not only
just flat, but it's deep and we have a
volume of every shade of colour with that
gigantic colour palette. There's the
problem - we will use the same name for
two different things.
Photo HDR and TV HDR are not the same! TV
HDR is exciting it's a different way of
displaying video with more luminance,
more colour and more contrast. It takes
both the display and the content to make
that happen. With HDR you got to have
content that's encoded in HDR, it's film
that way, you have metadata that goes
along it's layered on top of that HDR
video. Then you have to have a display
that's HDR capable. Meaning that display
has to have peak brightness of a minimum
of a thousand nits. Plus it's got to have
enhanced contrast and a very wide
colour gamut. Then that display reads
the metadata that comes along on that
HDR video stream and that display then
now knows how to display each one of
those pixels on the screen to make that
amazing HDR content. Whereas photo
HDR is a different process. Photo HDR is
using two or more independent photos
merging them together and taking
qualities out of each one to create one
finished product. There's a number of
different standards out there and the
issue is they're all independent. They're
not compatible with each other and we've
seen this in the industry before so
hopefully one day we'll settle on the
standard. But right now we're looking at
a couple of different ones that are out
there. And two of them more popular are the
HDR 10 and the Dolby vision. Is one
better than the other? Not necessarily -
they're both really good it's different
ways of producing that HDR signal. But
you got to make sure that whatever your
HDR content is, you have the right
display to go along with that.
