4K & Beyond Cont.
Miranda's
Kaleido-MX
multiviewer

switching
and
processing modules
as well as 4K support
in its Kaleido-MX
multiviewers.
And on the playout
and automation side,
Cinegy's broadcast
video player now
supports Sony XAVC
4K while Cinegy Air will
allow broadcasters to playout in
4K as well as streaming 4K via
IP (RTP/UDP).

Plugging The 4K Gaps
There are infinite amounts of
connections that need to be
made to preserve the quality
of a 4K signal all through the
workflow. Companies like AJA
address this by offering a range
of 4K capable products to help not
only with acquisition, but editing
and conversion.
AJA's 4K2HD and Hi-5 4K miniconverters help drive 4K, UHD
SDI and HDMI displays. The Io
4K capture and output hardware
provides support for the latest 4K/
UHD Thunderbolt 2 and 1-equipped
devices and the OEM-ready Corvid
Ultra system scales from a 4K frame
to HD for live and recorded work.
To handle 4K signal distribution,
extension and integration, Gefen
launched new UHD splitters for
HDMI 4K/2k, matrix switchers
for HDMI 4K/2k, and a new
4x1 switcher for HDMI 4K/2K
last September. Deltacast also
announced a number of OEM video
cards around that time, supporting
simultaneous 4K in and out at 30
fps or 4K-ready up to 60 fps.
And for the test and measurement
of 4K signals, the likes of OmniTek
now offer the Ultra 4K Tool Box,
which includes features for the
analysis, display, conversion and
generation of signals up to 4K/60p,
while Leader Instruments launched
its LV5490 SD to 4K multi-standard
multi-waveform monitor around
the same time.

AJA's 4K2HD down-converts
professional SDI 4K/UHD signals
to HD resolution

Realising 4K
4K is still far from being
the norm in live production. SD
distribution is common and the
majority of roll-outs are still
focused on HD. "Most of our rental
4K business is sports related, said
Tom Dickinson, CTO for Vitec
Group Services Division.
"The only 4K we are currently
doing involves HD extraction.
That isn't exactly 4K production,
it's a hybrid."
EVS Product Specialist Thierry
Pauwels concurs, noting that
apart from like 4K production at
the French Open last year, most
EVS 4K tests at sporting events
have involved capturing images in
4K zoom to feed them into a regular
HD production.
"All the pieces in the production
workflow can now address 4K,
though some are still in beta," said
Pauwels. "4K is most commonly
transported as four times 1080p,
which is a pain because now, you
have four cables instead of one."
Dickinson also notes that lens
flexibility and size is holding 4K
acquisition back. "The PL-mounted
single plane imager camera
technology is not conducive for
live sports, solely because of the
lenses. It's way too costly and
wastes production value."
The quality of true 4K also
depends on the ability to deliver
higher frame rates, higher dynamic
range and increased colour space.
"Some 4K is not true 4K at 60 or at
true colour depth," said Wheeles.
"When you go to build an end-toend solution, this comes to light."
Rowe concludes that nobody
has really put together a complete
4K production facility yet.
"We know how to do it and the
World Cup could be the catalyst for
that." And while 4K is achievable
on current infrastructure, both
Rowe and Wheeles feel that 8K
is one step too far at this point
despite NHK's plans for 8K Olympic
coverage in 2016. "If you look at
cost and technology difference to
get to that next step, it's several
years away," said Wheeles.
