Hitachi Kokusai Electric America, Ltd. (Hitachi Kokusai) will debut new features in its recently-introduced CU-HD550 camera control unit (CCU) at the upcoming 2020 NAB Show. New capabilities include simultaneous High Dynamic Range (HDR) and Standard Dynamic Range (SDR) output with independent adjustments, and 4K/UHD output over single-link 12Gbps SDI connectivity. The company will demonstrate these new functions alongside other Hitachi innovations in booth C4409 at the show, taking place April 19 to 22 in Las Vegas.
First previewed at NAB Show New York last fall, the CU-HD550 and its companion CA-HF550 camera adapter are designed to lower the cost of entry for 1080p60 video production. Also compatible with interlaced Z and SK-series Hitachi HDTV cameras, the full potential of these latest accessories are realized when combined with Hitachi Kokusai’s 1080p60-native camera heads to form video acquisition systems with progressive signal paths.
When used with an HDR-capable Hitachi camera model such as the award-winning SK-HD1800, new dual-workflow functionality in the CU-HD550 enables parallel HDR/SDR acquisition with a single camera by providing separate video shading adjustments for HDR and SDR outputs. This allows producers to fine-tune each output path to create content for distribution to both modern and legacy display platforms without the cost and operational burden of separate cameras.
Meanwhile, a new configuration of the CU-HD550 is designed for transforming natively-acquired 1080p video to 4K resolution and outputting the result over single-link 12G-SDI. The 4K output functionality supports High Dynamic Range when used with an HDR-enabled camera, while the color matrix of the 12Gbps SDI output can be switched between ITU-Rec.709 and BT.2020 color spaces.
“Our introduction of the CA-HF550 and CU-HD550 attracted a lot of interest by making broadcast-class 1080p60 production more affordable, and the new capabilities we’re unveiling at NAB add even further versatility and value,” says Emilio Aleman, Engineering Manager, Hitachi Kokusai Electric America, Ltd. “While 4K adoption is growing, HD production continues to thrive, with many high-profile events being produced natively in 1080p60 with HDR. The new 4K output feature is ideal for content creators who have some UHD production requirements but aren’t yet ready to invest in full 4K cameras and infrastructure, while the dual HDR/SDR workflow functionality helps producers optimally reach multiple generations of displays.”
Hitachi Kokusai will demonstrate the CU-HD550 and CA-HF550 at the 2020 NAB Show in conjunction with the aforementioned SK-HD1800 studio and field production camera. The feature-packed, 1080p SK-HD1800 combines the advanced, global shutter CMOS imaging technology first implemented in the company’s Z-HD5500 camera with a motorized, remote filter wheel to deliver image quality for mobile and event-based productions even in venues with challenging LED lighting and displays.
