Las Vegas -
University of Warwick spinout company GoHDR and home-theater display
manufacturer SIM2 will use the 2012 NAB Show
here this month to showcase new high-dynamic range (HDR) video technology using
content produced by GoHDR and a SIM2's HDR47E 47-inch professional LCD monitor,
developed several years ago with Dolby Labs.
GoHDR will present the world premiere of the
HDR video content, screened on the 47-inch HDR-capable SIM2 display.
The technology is
said to produce images with exceptional lighting detail. GoHDR has developed
compression technology that will enable the huge data streams produced by HDR
video cameras to be displayed on a TV screen.
"We are proud to
be part of goHDR's new video technology showcase in Las Vegas. Our HDR47E
monitor is a technological tour-de-force developed by SIM2 engineers to make
full use of the real-life dynamic range of HDR images," said Alberto Fabiano SIM2
USA executive VP. "The GoHDR presentation will be, yet again, another
opportunity to show the world SIM2's technology leadership: an experience that
streams down to our entire line of precision products hand-made in Italy."
Alan Chalmers, professor
of Visualization at WMG, University of Warwick and innovation director at GoHDR, said: "High Dynamic Range video is the next big step in TV imaging --
similar to the change from black and white to color TV. For the first time,
viewers will be able to see scenes on TV just as they would in real life, without
losing detail in the glare of bright sunlight or in deep shadow."
"The data stream
produced by HDR cameras is huge -- equivalent to a CD worth of data per second.
To address this issue, GoHDR has produced two products: an encoder which
compresses the data to allow it to be transferred to a display, and a media player, which reverses the process and allows the pictures to be viewed with
all the glorious lighting detail preserved," said Chalmers.
"We are very
excited to be working with SIM2 to display HDR content on the world's first
commercial HDR display," says Professor Chalmers. "TV viewers will get an
exclusive glimpse at the significant difference that this technology will make
to their viewing experience. HDR is coming. At NAB you will be able to see what
the future will be like."
Over the past two
years GoHDR has had exclusive access to the true HDR video camera, built by
German company SpheronVR, and has produced a number of short films to showcase
This will be the
first time the company has been able to demonstrate its work, using SIM2's
HDR47E monitor, to a wide audience, outside the laboratory.
The film clips
produced by goHDR are also available on www.gohdr.com,
where they have been specially treated, using a technique called tonemapping,
to give an idea of what they would look like on an HDR display.
