Ikegami SHK-810 8K UHDTV camera

Ikegami Electronics Europe will demonstrate its latest television production and monitoring equipment on 8 June 2016 at MMC Studios in Cologne. The main focus of the event will be on the 8K Super Hi-Vision /4K UHD switchable SHK-810, the UHK-430 4K camera and the iHTR 4K Video Packetising Optical Multiplex Fibre Transmission system.



SHK-810 8K/4K switchable camera

Designed in collaboration with NHK, the SHK-810 is Ikegami’s fourth-generation 8K camera. It employs an 8K native 33 million-pixel Super 35 CMOS sensor achieving 4000 TVL horizontal and vertical resolution. The sensor allows the tight depth of focus often chosen for high-impact drama programmes. The SHK-810 provides 8K, 4K and 2K output. It can be used in a fully 8K production environment or alongside 4K and/or 2K cameras. Regular PL-mount lenses can be used.

8K offers 16 times more image detail than HD and delivers very sharp images on screen sizes or 85 inches or more. Public demand for 8K content is expected to be driven by coverage of the 2020 Tokyo Olympics. Ikegami is confident that 8K Super Hi-Vision will prove extremely useful across a wide range of applications including broadcasting and healthcare.

Ikegami UHK-430 4K UHD camera

4K resolution and high dynamic range have become important issues throughout the broadcast media industry as content producers and delivery channels plan their investment strategy for the coming five to ten years. The first in Ikegami’s new-generation Unicam XE range of cameras, the UHK-430 incorporates three newly-developed 4K-native 2/3 inch eight megapixel CMOS sensors which provide full 3840 x 2160 ultra-high definition resolution plus the depth of field required for studio and outdoor production. The UHK-430 delivers four times more image detail than high definition and has a colour depth of 10 bits per pixel instead of the current limit of 8 bits per pixel.

The UHK-430 incorporates 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 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.

At the heart of the UHK-430 is a new processor, the AXII, reducing power consumption and delivering a wide range of features including 16-axis colour correction and new focus-assist for 4K and HD video modes. The AXII also provides the processing for Ikegami’s newly developed i-Log transfer characteristic which delivers high contrast for a wider dynamic range. This allows more image information to be retained for greater headroom and colour grading. The ITU-R BT. 2020 extended colour space specification is supported in 4K mode. BT. 709 colour space is supported in both 4K and HD modes.

Ikegami viewfinders available for the UHK-430 include the 7.4 inch OLED VFE741D, the 7 inch full HD resolution LCD VFL701D LCD and the 2 inch portable LCD VFL201D. All three include a serial digital interface for integrated camera and viewfinder menu control.

The companion Ikegami CCU-430 camera control unit enables easy migration from HD to 4K live production. Features include switchable 4 x 3G-SDI 4K output as well as HD output. An optional plug-in board makes 4K video, HD video, and HD cutout from 4K available simultaneously. 12G-SDI and video-over-IP interfaces will be introduced in the coming months.

A built-in 40 gigabits per second optical transceiver delivers full bandwidth 4K RGB 4:4:4 component channels from camera to CCU, allowing very high quality chroma keying. Dual HD outputs are provided for teleprompt and talent monitor plus return video lines from studio to viewfinder. The UHK-430 also has a Gigabit Ethernet data port to allow networked control.

iHTR Multi-Camera Optical-Fibre Transmission System

The iHTR series multi-channel optical multiplex fibre transmission system. This comprises a range of modules which can be selected in various configurations to match a specific operational requirement. Up to 20 gigabit per second multiple full-bandwidth uncompressed camera feeds, and optionally power, can be delivered along a single cable.

The system is more compact than traditional multi-cable alternatives and can be deployed quickly. Applications including high capacity low-latency data links within or between buildings, outside broadcast coverage from a sports venue or event hall, live broadcasting from locations requiring secure electrical power, and emergency surveillance.

Central element of the Ikegami iHTR series is the iHTR-100 bi-directional interface. This allows six HD-SDI camera sources and two return video channels to be multiplexed along a dual-core optical fibre. When connected to a second iHTR-100 module, the combination delivers video across distances of up to 20km. Direct-current power can be delivered up to 1km to remote cameras using the iHTR-103 transmitter and iHTR-104 receiver modules.

A typical configuration can accommodate six cameras covering a field or stage to a 1km distant OB vehicle or control room, including return video channels. Where remote power is not required, six camera can be linked to control-area feeds as far as 20km away along with two return video channels. In all instances, the iHTR system can be accessed via 100 BASE-TX networked personal computers.
