Achieving Optimal Quality
Contributing Editor David Kirk examines
the perpetual quest for optimal quality in
both picture and sound...

A

chieving Optimal Quality will be
the central theme of the 2016 NAB
Show in Las Vegas, as it has been since
I commenced the annual pilgrimage
in 1985. The specific focus this year
will be on 4K Ultra-High Definition.
Broadcasters are faced with an ever
widening range of standards, shortly
to embrace 8K in Japan at least where
regular test transmissions commence
this year.
Audio technology reached an
impressive level of realism with the
introduction of the 44 kHz Compact
Disc format back in 1982. It is my
prejudiced opinion that a decently
recorded CD heard on decent
transducers, ideally Bose QC15 noisecancelling headphones, very closely
matches concert-hall reality. Okay
the sound is between the ears rather
than external but, with a few years'
practice, that almost becomes an
advantage.
Human visual senses are much less
easily deceived than human hearing.
The only really convincing viewing
devices, short of direct sensory
induction, are likely to be head-worn
displays once these reach convincingly
realistic image quality and tolerably
low bulk. In addition to higher
resolution, the development path in all
aspects of video capture, processing
and display is now into high dynamic
range and - at least for slow motion
applications - higher frame-rate.
So, what is both new and optimal
quality at this year's NAB Show?
AJA Video Systems' Ki Pro Ultra
is a file-based 4K/UltraHD and 2K/
HD video recorder and player with a

built-in HD LCD monitor. Ki Pro Ultra
is capable of capturing edit-ready
4K (4096 x 2160), UltraHD (3840
x 2160), 2K (2048 x 1080) and HD
(1920 x 1080) Apple ProRes files.
Ki Pro Ultra also supports a range
of video formats and frame rates up to
4K 60p, and offers flexible input and
output connectivity - including 3G-SDI,
fibre and HDMI.
Bridge Technologies will show
a new graphical data analyser that
allows users to play through recorded
data in a timeline display to observe
correlations and patterns of errors
occurring over any time period.
An archive server provides the
data recording capacity in a simple
connect-and-forget form, with each
archive server retaining recorded
data for up to 25 services. When
connected to the company's VBC
controller and configured through
a simple setup routine, the server
automatically activates the VBC's
timeline analysis capability. Operators
can search through a chain of events
that led up to service failures, and
generate reports for remedial action
or fulfilment of regulatory SLA
obligations.
CEDAR will exhibit DNS 8 Live, a
dynamic noise suppressor designed
specifically for live use. With eight
simultaneous channels of dialogue
noise suppression (formatted as AES3
on XLR sockets plus DB25 using
the AES59 pin-out) it uses simple
controls and as a detailed editing
mode. A standard 4-pin 12 volt DC
input has been added.

Ikegami's UHK-430 4K/HD portable camera system

Ikegami will launch its new UHK430 4K/HD portable camera system
at NAB. First in the company's Unicam
XE series, the UHK-430 employs three
newly-developed 4K-native 2/3 inch
CMOS sensors which provide full 3840
x 2160 ultra-high definition resolution
plus the depth of field required for
studio and outdoor production. The
camera is equipped with a B4 bayonet
mount compatible with 2/3 inch HD
lenses. An optional SE-U430 expander
accommodates large studio or OB
lenses. Two piece construction allows
the UHK-430's sensor and lens head to
be detached as a compact unit for easy
deployment on a support devices such
as long-reach manually-controlled
camera poles. In this mode, the head
can be operated up to 50 metres
from the camera body. The head can
also be replaced by other assemblies
such as a Super 35mm large-sensor
front-end. This will be compatible
with Positive Lock lenses. Camera
heads for special applications will
become available as part of the UHK430 product range, including a high
frame-rate version. Additional features
include 12G and IP CCU outputs and a
new Ikegami processor which allows
40 gigabit/s uncompressed baseband

video transmission. A high frame-rate
option will provide easy access to
slow-motion effects both for sports
and stage-event coverage. The new
processor enables the UHK-430 to
deliver a wide range of features
including a 16-axis colour matrix
and focus-assist for 4K and HD video
modes. BT.2020 extended colour
space specification is supported in
4K mode. BT. 709 colour space is
supported in HD modes and can also
be switched in during 4K operation.
JVC will show its new GY-HM200SP
compact sports production camcorder
which has an integral score overlay
and game clock. Full Auto Mode
along with single-button streaming is
intended to makes the camcorder easy
for an untrained operator to use. PC
software enables the user to store up
to 90 team names and logo bitmaps
within the camera. The user can then
select 'left' and 'right' teams from this
stored list. The camcorder captures
to hot swappable SDHC/SDXC cards.
When one card is full, the camcorder
switches to the other. Features include
a 1/2.3-inch BSI CMOS imager and
integrated 12x zoom lens with optical
image stabiliser and 24x dynamic
