Hitachi To Show HD-HDR Studio Camera With Remotely Controlled Filter Wheel

At the 2019 NAB Show Hitachi Kokusai Electric will show a new HD studio and field production camera with HDR acquisition capability that features CMOS imaging technology and a motorized, four-position filter wheel for remote operation. This allows the new SK-HD1800 to deliver high image quality for mobile and event-based productions even in venues with challenging LED lighting and displays.

The SK-HD1800’s progressive-scan, CMOS imagers (with global shutter) are ideally suited to environments where LED lights or large LED displays are used. The advanced 1080p sensors combine with Hitachi Kokusai’s digital signal processing and low-noise circuit technology to deliver pristine visual quality with superior sensitivity, excellent color fidelity and a remarkable 62dB signal-to-noise ratio, according to the company.

John J. Humphrey, Vice President of Business Development, Hitachi Kokusai Electric America Ltd., said features like a remotely operated, motorized filter wheel have made the SK series of cameras a preferred choice for remote and mobile productions. The new SK-HD1800 combines with the CU-HD1300 family of camera control units (CCUs) to flexibly support High Dynamic Range (HDR), 4K and IP-based workflows.The camera supports the HLG (Hybrid Log-Gamma) and HPQ HDR formats, which is compatible with the HDR10 open standard for consumer TVs.

Pairing the SK-HD1800 with a CCU from Hitachi Kokusai’s CU-HD1300 series CCU system supports both SMPTE fiber and digital triax connectivity, and can be combined with a dedicated fiber or triax CCU or with Hitachi’s dual-cable CU-HD1300FT.

An optional 4K output module for the CU-HD1300 transforms natively acquired 1080p video from the SK-HD1800 to 4K/UHD resolution and outputs the result over single-link 12Gbps SDI or quad-link 3G-SDI connectivity. Meanwhile, a SMPTE ST 2110 option for the CU-HD1300 enables seamless integration of the SK-HD1800 camera system into next-generation IP-based production workflows, supporting broadcasters’ transition from traditional baseband video infrastructures to more flexible media networks.

Both the 4K output and SMPTE ST 2110 transport options fully support the HDR capabilities of the SK-HD1800. In addition, a firmware option for the CU-HD1300 enables users to acquire optimized HDR and standard dynamic range (SDR) video simultaneously with a single camera by providing separate video shading adjustments for HDR and SDR outputs.
