D-CINEMA 3D AND 48fps SINGLE-BOX REPLAYS FROM DOREMI
Doremi Technologies now offers capabilities for D-Cinema replays to provide
enhanced viewing experiences. Additions to the 2K-capable Doremi V1-HD server
complement new features of the latest TI technology-based DLP projectors to
create something more than a film replacement. Doremi have worked with TI to
provide single-box 3D and 48fps replays, with high bit rate JPEG2000 ‘visually
lossless’ compression quality.
DLNK-2K is the basic Dual Link and 2K option for the V1-HD. This now can add 3D
and 48fps modes to take advantage of the new TI technology for their larger DLP
projectors to display either 3D or 48p film playback. The original media is a
file in 1920 x 1080 at 48fps which is built from two interleaved 1920 x 1080
24fps images. The 3D feature supplies two motion streams for left eye and right
eye that are simultaneously replayed at up to 1080/24p, and a single projector
displays both these to give real 3D. Compared to traditional methods this avoids
using a second projector and all the associated alignment procedures between
them needed to produce convincing 3D.
D-cinema can now put a new spin on the double shuttering technique used by film
projectors to reduce flicker by showing each twice. Now, if original material is
48fps this can be replayed at that full rate using the new 48p mode on the V1-HD
for display as a dual interleaved 24p to generate 48 full progressive 1080-line
images on the screen. This not only reduces flicker but also gives smoother
motion rendition.
“Everyone knew that D-cinema would diverge from celluloid and it is happening
already,” says Patrick Zucchetta, Head of Business Development at Doremi
Technologies. “It is now much easier and more effective to show 3D material from
just one player and one projector. Providing a 48Hz frame rate means yet better
images with motion that is really smooth and gives flicker-free viewing. The DLP
projectors are ready for this and we can supply the signals in an economic and
reliable way in a single-box solution and with JPEG2000 quality. It’s important
that cinema should always be something beyond home viewing – and this certainly
is!”
The DLP projection technology from TI includes imaging chips that are capable of
showing much higher image refresh rates than normal film or television. With new
interfaces in place and high-speed high-quality replays available from Doremi,
the scene is set for the further enhancement of the D-cinema experience.
