The CU-HD1500 and the CA-HF1500 constitute the camera control and transmission system for the new multi-standard camera SK-HD1500. The
Camera Control Unit CU-HD1500 provides significantly reduced power consumption and improved functionality. SDI
（ 1080i/720p/480i/ 576i ）
inputs/outputs are offered as standard. This flexible system is capable of providing many modern HD/SD-SDI video signals required by today's HDTV
program production demands.
HD up-converter
The HDTV up-converter for displaying the SDTV return signals in the
HD Viewfinder is provided as standard with the CU-HD1500. The up
converter is of a line-correction type capable of displaying 1080
effective scanning lines. In addition, AUX and Return color signals
can be displayed in the TFT-LCD color viewfinders offered.
High-quality digital transmission using optical fiber cable.
An HFOC (Hybrid Fiber Optic Cable) is used to connect the camera
adaptor (CA) and the camera control unit (CCU). The 6Gbps signals
are transmitted using two spectra of 3G-SDI to ensure high-quality
and wide-band transmission.
The effective HFOC length can be up to 4,000m (13,200 feet) with
no utility power and up to 10km with normal single mode fiber (2
required per camera).
SDI Embedded audio Two channels of MIC audio can be
embedded in HD-SDI/SD-SDI output.

ACCESSORIES
Versatile CCD drive functions
Three modes of shutter operation are provided in the SK-HD1500
camera system :
Four PRESET electronic shutter speeds, for stopping action or fast
moving objects in the image.
LOCK SCAN to image non-synchronous displays without flicker.
Automatic Electronic Shutter (AES) maintains the video level when the
maximum F-stop shooting condition is reached.
Motorized and remotely controlled optical filters
In traditional photography, ND filters are used for depth of field control.
Four optical ND filters are provided as standard on a motorized,
remotely controlled filter wheel. These are: Clear, 4-point Cross,
1/16ND, 1/64ND.
Full auto mode
The AES and automatic iris maintain the video level even with rapidly
changing light intensity. These functions are accessed via the menu
system or the shutter buttons provided on the RU-1500JY and
SU-1000 remote control panels. Full-time Auto White balance (FAW)
corrects in real-time color temperature variations due to changing
types of lighting conditions on the scene object.
ECC (Electronic Color Correction)
Due to the wide gain characteristics of the SK-HD1500, the ECC
function corrects color temperature electronically by providing preset
gains to equal color temperature gradations of 3200K, 4300K, 5600K,
6300K and 8000K.The ECC can be controlled by the remote control
panel and the base station like an optical filter. The setting can be
stored in the Scene files and its status can be displayed on the view
finder and the monitor output.
Optical and image capture functions
Programmable soft-switches (CS-1, CA-CS)
The operator or cameraman/woman can assign Zebra, marker, VF
Detail, Quick Focus or FAW to the CS-1 switch via the operation menu.
The CA-CS switch can take on the functions of VF Detail on/off,
marker-1 or marker-2 on/off.
Viewfinder options
Three viewfinder options are offered with the SK-HD1500 camera
system. Black & White CRT-type viewfinders are manufactured for ENG
(2-inch) and OB (5-inch). These are of high-brightness and contrast
making them ideal for easy visibility in field production.
A 9-inch color TFT-LCD screen viewfinder is offered for critical viewing
such as encountered in studio productions.
Viewfinder markers & functions
The SK-HD1500 provides an excellent gamut of thoughtful viewfinder
markers and functions to aid the camera operator in providing
outstanding results during a TV program production.
All VF parameters can be stored in 4 dedicated memories which can
catalog preferences for different operators, programs, shooting
conditions or events.
Programmable functions include; color/mono, detail, crisp, safety zone,
2 movable markers, center cross-hair, 2 movable effects boxes, variable
aspect ratio side panels, side panel contrast/ bright, 2-mode zebra and
variable line display level polarity.
Advanced Flicker Reduction Function
The video flicker seen in a modern HDTV slow-motion camera is mainly
caused by the asynchronous frequencies between the camera’s CCD
scanning and the charge-discharge cycles of artificial lights typically
used in stadiums, arenas and auditoriums.
The SK-HD1500 can minimize the observed flicker in the image by its
unique, automatic flicker-frequency detection algorithms which use the
actual level fluctuations in the captured video frames to correct the
flicker in real-time.
The optimum reduction in flicker can be thus easily obtained by
adjusting the detection response and method via the SK-HD1500
operational menu.
Focus Assist
Advanced Focus Assist Functions are available to support the camera
operator in finding the right focus regardless of the viewfinder model
used. The Area Marker detects edges inside area, while a focus
indicator shows the actual detail level by a horizontal line. A Focus
Indicator Gauge can further be set to lock the maximum achieved level
for a few seconds.
Ease of use characteristics & functions
The SK-HD1500 incorporates heavy duty mounts for both the ENG and Studio viewfinders.
Comprehensive control panel
In Studio and Field production, the panel provides the camera operator
with a wide array of controls for intercom audio, program audio, aux
video switching controls, script lamp connector, dual-tally and call
functions the norm in high-end broadcast cameras. These functions
along with available 100VA of teleprompter monitor power and
dedicated prompter SD signal make the SK-HD1500 a logical choice
for sophisticated productions.
Camera head inputs & outputs
The camera head provides 2 buffered HD-SDI, 1 SD analog teleprom-
pter out, and 1 HD-SDI switchable as Monitor or VF and RET video
output via BNC connectors. The MIC-1 channel is switchable with
balanced XLR input connector located at the front of the camera
(shotgun mic) or at the rear of the CA-HF1500. All the microphone
inputs provide phantom power supplies and accept mic or line levels.
These IOs satisfy a wide variety of production requirements.
Viewfinder status displays
Iris F-stop, Lens Externder position, Shutter speed, Optical and ECC
filter in use, and Gain setting are all displayed or defeated via menu
selection. Menu selection also includes the over-level or between
range-type zebra are also provided.
Quick focus + Precision Focus (Auto Focus)
The Quick Focus function automatically opens the iris then sets the
video level with the electronic shutter. The resulting shallow depth of
focus, allows the cameraman to set the exact focus with ease.
Lenses with Precision Focus(Auto Focus) technology are supported
equally.
