Ikegami Reports Ongoing
Transition from HD-SDR to
UHD-HDR and SDI to IP Broadcast
Production Through 2022

kegami reports ongoing broadcast
and professional media innovation
throughout 2022 with a continuing
transition from HD-SDR to UHDHDR
across the EMEA markets and
worldwide. Ikegami innovations
announced during the year included
the Unicam UHK-X750 IP-capable
UHD HDR HFR camera plus
the
R2 Real Remote production system.
" UHD-HDR has replaced UHD-SDR
as the default standard for consumer
TV displays in the retail market, "
says Michael Lätzsch, Broadcast &
Professional Video Division Manager
at
Ikegami Electronics
GmbH.
" This in turn has
broadcast-focused
(Europe)
encouraged
production
companies to invest in UHD-HDR
camera systems. UHD-HDR content
is becoming increasingly available
online
from dedicated
streaming
channels. A growing number of
broadcasters are also supplementing
their HD-SDR terrestrial and satellite
transmissions with online UHD-SDR
content. "
" The transition from SDI to IP
continues
technology
to gain
momentum for studio and
field applications, given
the
greater system flexibility and easy
expandability of IP, " adds Alan Keil,
Vice President
and
in
strong demand,
Director of
Engineering at Ikegami Electronics
(USA), Inc. " HFR shooting is
additionally
especially for slow-motion coverage
of sports. "

front end of the
UHK-X750 are three 2/3-inch CMOS
UHD sensors with a global shutter
to minimize artifacts when shooting
LED screens or scenes illuminated
with flash or strobe lighting.
Full HDR/SDR support is included
plus the ability to choose between
BT.2020 and BT.709 color spaces.
High-frame-rate shooting at up to
2x speed in UHD or up to 8x in HD
via the base station is possible
as an option. Five neutral density
filters (clear through to 1/64) and
four chroma filters
(3200, 4300,
6300 and cross) are included plus
provision for an optional optical lowpass-filter
to minimize moiré effects
when televising subjects such as LED
video walls.

production system, announced at
necessary to guard against infection,
particularly in close-up sequences.
It is designed for use with cameras
such as the compact full broadcast
quality UHD/HD Ikegami UHL-43.
Support is provided by a six-axis
programmable articulated robot arm
mounted on a motorized pedestal.
This combination allows fast changes
in camera height from a 400 to
2,350mm above floor level.
Integral
automation enables
precise control of camera motion.
Individual or simultaneous changes
in the angle of view can be captured
live and stored as a preset. Camera
and support movements
reproduced
can be
directly
from stored
memory. Multi-vector motion
sequences
can be achieved
smoothly, quietly and fully remotely
under timeline-based
control.
Forward, backward, sideways
and height parameters can all be
rehearsed, stored
and
adjusted,
including bird's-eye views. Motion
data can be entered via a graphic
user interface and real-time or
recordable joystick. A viewfinder in
the GUI displays the incoming video.
Occupying just 1,100mm in pedestal
width and depth, the R2 is much
more compact
than a traditional
studio crane and can be relocated
easily from one studio to another.
