Hitachi Kokusai Electric has developed the SK-UHD4000, a broadcast 4K Ultra HDTV camera system which can use the 2/3-inch B4 mount lenses used in conventional HD broadcast cameras. The system is scheduled for release in October.
The use of standard HD lenses with the SK-UHD4000 eliminates the need for special conversion adapters, and allows broadcasters to use existing lenses and shoot video in 4K resolution. The 4K Ultra-HDTV camera system is designed to provide solutions to the challenges of live outside sports broadcasts, such as sensitivity and depth of field. The newly developed 2/3-inch MOS sensor makes it possible to produce video images with high sensitivity and high resolution.
The company promises a number of key features, including direct installation of B4 lenses for conventional HD broadcast cameras; handling and operability on par with existing HD broadcast cameras; high quality video in 4K resolution; and a small 2U-size 4K camera control unit. The SK-UHD4000 also boasts low power consumption, the company claims, with the amount of power consumed by the camera head having been reduced to 38W, which is equal to the power consumption of a 1080pHD broadcasting camera.
This camera system will be exhibited at the Hitachi Kokusai Electric booth at IBC2014, stand 11.D39.
