4K Ultra HD Television Production Camera
1 2
Hitachi's SK-UHD4000 system 4K color camera can be used with existing 2/3-inch
format ENG and Studio/Field lenses without the use of an optical-mechanical adaptor
between camera and lens.
2/3-inch lenses are the industry standard for studio and outside broadcast (OB) live
event production applications. The extended depth of eld required in sports television
production is therefore preserved.
A unique, high-precision 4-sensor optical system and latest MOS sensor technology,
provide 4K (3840 X 2160) and 2K (1920 x 1080) video simultaneously.
Camera controls and footprint are the same as current broadcast HDTV cameras
making it simple to replace existing 2K infrastructure with minimal diculty.
The use of a B4 (BTA S1005A) 2/3-inch lens format
overcomes many objections to the wide adoption of 4K
for TV program production including the use of Cine-style
lenses, shallow depth of eld and the limited ergonomics
of Cine-lens operation.
The use of a 4-port RGB color separating prism is instrumental in achieving the
performance of a 4K 35mm single CFA sensor in a standard portable camera chassis.
It is also the best method for preserving lens MTF (Modulation Transfer Function) to
provide the utmost contrast in 4K images produced by the Hitachi's SK-UHD4000
camera. The camera’s optical block employs 'dual-green' and 'pixel oset' technologies
to dramatically increase resolution in the Y (luminance) channel. Using highly accurate
sensor placement and Hitachi's advanced digital signal processing (DSP), the SK-
UHD4000 creates high resolution images from a total 8.8 million eective pixels.
The SK-UHD4000 camera system utilizes industry standard Hybrid Fiber-Optic Cable
(HFOC) connectors made of high-strength materials to ensure durability and reliable
performance under the most demanding TV production conditions.
Maximum HFOC length with applied camera power and fully operational facilities is
4,000m (13,200 feet) with no utility power*. The Optical power meters on the CCU
front panel indicate the optical condition of both transmitting and receiving signals
independently to accurately depict proximity to the “digital cliff” (maximum cable
distance) .
Each essential part of the Hitachi's SK-UHD4000 camera system has its own DSP
processor. Dierent DSP ICs are used independently for 4K camera head processing,
the transmission system and Camera Control Unit (CCU) processing. New, power
efficient Hitachi Digital Signal Processors are designed to work with any 4K imaging
technology now or in the future, oering a high ROI (return on investment).

It is dependent on type of lens used, viewfinder, studio adaptor, teleprompter, HFOC, connectors
and other
accessories that may be connected thereby consuming power otherwise available for the camera head.
