Ikegami representatives head to the Dubai World Trade Centre in March for CABSAT 2020, the largest broadcast media show in the Middle East region. The exhibition together with its supporting conference and workshop will be held from March 31st through April 2nd. Highlights of the Ikegami exhibit on stand C4-20 will be the UHL-43 compact HDR camera which was shown in prototype at CABSAT 2019 and is now fully deliverable, the UHK-430 system camera with IP interface and the HQLM-3125X master grade video monitor.
Ikegami UHL-43 compact 4K HDR camera
The Ikegami UHL-43 is a compact HDR camera designed for applications such as robotic studios, outside broadcasting of live events, parliamentary television, point-of-view image capture, weather coverage, traffic surveillance and public security monitoring.
The UHL-43 employs three 2/3-inch 4K-native 8.3 megapixel CMOS sensors in the same workflow and remote control structure as Ikegami’s Unicam XE series UHK-430 and UHK-435 cameras. Unlike cameras using a single chip or pixel-offset technology, the integration of three 3840 x 2160 resolution CMOS sensors and prism optics provides true UHD capture resolution, high quality colour reproduction and complete freedom from colour aliasing. Measuring only 145 x 155 x 169 mm WDH and weighing just 2.6 kg, the camera head can be used on practically any support device such as a shoulder harness, long-reach arm or overhead mount.
Combining high sensitivity (F11 in 4K 50p) and very high signal-to-noise ratio (typically 62 dB), the UHL-43 can be deployed even in conditions of low illumination. Fully supporting HDR, it delivers detailed picture quality across the full range of brightness levels from deep black to peak white while also capturing wide colour gamut. HLG mode is included, conforming to the ITU-R BT.2100 international standard for HDR. Custom gamma curves can also be set and stored within the camera, allowing the implementation of any desired curve.
The UHL-43 is available as an HD-HDR model which can be upgraded via a retrospective software update to deliver 4K-UHD. Output options supporting 12G-SDI or 4 x 3G-SDI over coaxial cable or 12G-SDI over optical fibre are available. An RJ45 Ethernet connection enables remote camera operation via network hubs with low latency for use in remotely controlled studio production.
Control functions are accessible at the camera head or via a choice of remote control panels from Ikegami’s OCP-series. The integral Ethernet interface allows easy control from practically any distance, making the camera ideal for remotely supervised outside broadcasting.
Ikegami UHK-430 4K studio camera with optional Media-over-IP Gateway Module
Ikegami’s UHK-430 is a 4K-native studio camera system with simultaneous HDR/SDR processing. Its three 2/3 inch CMOS sensors provide full 3840 x 2160 UHD resolution plus the depth of field needed for studio and outdoor production. The camera is equipped with a B4 bayonet mount compatible with 2/3 inch UHD and HD lenses. An optional SE-U430 expander accommodates large studio or OB lenses.
Designed to slot directly into the UHK-430’s CCU-430 control unit, Ikegami’s 4K Media-over-IP gateway module allows 4K UHD video and additional signals such as intercom, return-video feeds to be exchanged between the CCU-430 and a local IP network hub. It enables easy and low latency signal distribution via a light weight optical fibre instead of requiring multiple SDI cables.
Uncompressed video can be transmitted via an integral optical interface using either one 25 GbE or two 10 GbE SFP modules. Redundancy can be implemented easily to ensure reliability by installing additional SFP modules. The MoIP interface module can be combined with an HD output option to deliver 2160p, 1080p and 1080i over IP and/or SDI simultaneously. Many broadcast systems currently use a mix of SDI and MoIP. For easy workflow transition, 2 x 12G SDI is therefore included as a standard.
Additional features of the UHK-430 include the newly-developed Ikegami AXII processor which allows 40 gigabit/s uncompressed full bandwidth video transmission. This processor enables the UHK-430 to deliver a wide range of features power-efficiently, including 16-axis colour correction and focus-assist for 4K and HD video modes. BT.2020 extended colour space specification is supported during 4K and HD operation. In its standard form, the UHK-430 weighs just 4.5 kg and comes with a 2 inch viewfinder and portable lens. Camera head dimensions are 149 mm wide x 243 mm high x 340 mm front-to-back.
HQLM-3125X master grade video monitor
Ikegami’s recently introduced HQLM-3125X is a 31 inch 4K-UHD master-grade monitor with 4,096 × 2,160 pixel 10-bit resolution and high brightness (1,000 candela per square metre). Fully compliant with BT.2020 wide colour gamut, the monitor is designed for critical image evaluation in broadcast production control environments. It employs a double-LCD-layer panel delivering a 1,000,000:1 contrast ratio with true black reproduction. A layer of light-modulating cells allows pixel-by-pixel control of backlight intensity, reducing light leakage and black float while reaching a black-level of 0.001 cd/m². Standard features include two 12G/3G/HD-SDI inputs and outputs, three 3G/HD-SDI inputs and outputs plus an HDMI input. The HQLM-3125X can thus accommodate a total of three simultaneous UHD feeds.
Viewing angle for critical image evaluation is a wide 178 degrees (horizontal/vertical). 1D and 3D LUTs are supported. The HQLM-3125X can be controlled remotely via Ethernet, RS-485 or locally from the front panel.―BCS Bureau
