Camera power and cable condition supervision are also performed when
using standard SMPTE311-type Hybrid Fiber Cable. Full Auxiliary (up to
4 digital, HD or SD) video return and individual trunk video function for
one HD-SDI that use the space band of 1.5Gbps except triple speed
band of 4.5 Gbps are with a total of the SK-HD1500 transmission
system. The maximum HFOC length with applied camera power and
fully operational facilities is 4,000m (13,200 feet) with no utility power.
Unique to cameras in the SK-HD1500’s price range are optical power
meters at the camera head (via engineering menu) and on the front of the
CU-HD1500 camera control unit. These meters indicate the optical
condition of both the receive and, transmit signals independently to
accurately depict the proximity to the “digital cliff”, maximum cable
distance or provide basic fiber cable diagnostics in the field.
*HFOC distance with applied CCU power differs depending on the system configuration.
It is dependant on the type of lens used, viewfinder, studio adaptor, teleprompter and
other accessories that may be connected and thereby consuming power otherwise
available for the camera head.
Hitachi has brought to market the first 6Gbps, fully digital optical
transmission system in an HDTV production camera. It is the most
accurate transport available for the 10-bit, 1080i 150/180 images from
the camera head to the camera control unit. All command audio and
video signals to and from the camera are digitally transmitted hence,
totally immune to EMI/ RFI interference.
The SK-HD1500 is HITACHI’s fifth-generation, triple-speed, slow-motion
HDTV Studio and Field production camera. It has been especially
developed in response to increased market demand for the acquisition
of high-quality HDTV images in sports and action events.
The pristine image starts with an excellent signal-to-noise ratio of -58dB
which is attained by employing the latest Ultra-Advanced,
High-speed/Sensitivity CCDs, state-of-the-art 16-bit analog to digital
converters and patented HITACHI digital processing technologies.
The camera system outputs these slow-motion frame rates: 1080i/180
or 1080i/150, 720p/180 or 720p/150. It simultaneously outputs normal
speed images [1080i/60, 1080i/50, 720p/60, 720p/50] from its camera
control unit (CCU) thus allowing dual recording of 2 different HD signals.
The SK-HD1500 can effectively be deployed in camera positions within
a venue replacing normal frame-rate HD cameras costing just as much.
Luminance response tools
Selectable gamma tables
In addition to normal gamma point and balance adjustments, the
SK-HD1500 offers a multi-point gamma table that provides the user
with exposure control over just the darkest points in the image. It
enables adjustment of the initial gamma gain to optimize the repro-
duction of dark scene components. Hitachi’s DSPs assure that no
additional noise components are introduced in the image even with
the most aggressive Gamma Table settings. Additionally, this function
does not change any of the other parameters of the video signal thus
maintaining overall exposure, detail, color reproduction and composition.
Black stretch
Black stretch function allows for better reproduction of dark or
underexposed areas by evenly raising the luminance response without
changing the pedestal or white clip/ knee settings. It is especially
useful in high contrast image venues, outdoors or sport productions.
Linear and auto-knee
Like the peak video level control function of the white clip; the linear
knee function is made up of the actual knee (level compression) point
and its slope which improve overexposed portions of the picture by
compressing the video past a certain point. These points are user
adjustable.
The auto knee provides the perception of a wider dynamic range by
dynamically compressing (varying knee and slope) the video level in
accordance to the strength of its over-exposure.
Ultra Gamma
This function dramatically increases the exposure latitude of the camera
in shooting conditions where the intensity of lighting and scenery varies
widely. Seven different ultra-gamma responses are pre-programmed to
suit just about every possible adverse shooting condition.

Lens optimization
Gray-Scale automatic setup
The SK-HD1500 offers the Gray-Scale Automatic Setup function to
optimize the optical parameters that could negatively affect the image
you are trying to capture and faithfully reproduce. The Gain, Gamma,
and Flare are the video signal functions that vary from lens to lens.
Color reproduction excellence
Picture sharpness enhancement
Triple-masking
The triple-masking function includes the 12-vector, linear matrix and,
Skin-tone masking provide the user wide latitude in subject image color
control. The 12-vector color corrector provides independent control of
the hue and saturation for six primary and six secondary combinations
of colors. The 6-axis linear matrix provides overall color control thereby
providing the user with excellent and precise color rendition control.
Skin-tone masking
The Skin-tone masking function provides “fine Painting” (hue and saturation)
of Skin tones without affecting other colors in the scene. This functions
additional and independently from the linear and 12-vector-masking
functions thereby adding an additional color-correction (Triple-masking)
Channel to the overall image color control.
Skin-tone Detail
The Skin-tone Detail functions allow a flesh color-based softening of
the image to achieve the impression of more youthful TV personalities.
2 individual memories exist as well as a function to automatically
detect the hue, saturation and luminance of the Skin-tone to be
affected. This function is not limited to Skin-tones only ; it can
increase or decrease the sharpness of any pair of colors in the image.
Knee Saturation
The Knee Saturation function dynamically restores color saturation to
scene highlights above the Knee point. Color-saturated highlights lost
in overexposed scenes are now visible. This function provides
excellent results ; for example when imaging : high-contrast, sunny
outdoor scenes, fireworks, concerts, theatre stage lighting, and
colored night scenes.
Master Detail items
Master Detail items are available to adjust various parameters of the
detail signal to taste or to achieve a desired “look” in your productions.
Some of these adjustments are ; H/V detail, crisp, level dependence,
knee detail, limiter, source, frequency and balance.
Lens Files
The SK-HD1500 can store 8 lens files which include various lens
correction data such as vertical modulation shading.This lens
correction data can also be stored in a card (SD card), where it can be
recalled when necessary.
Absolute detail control
Hitachi provides 3 major detail controls designed to precisely place,
control and shape the picture sharpness characteristics of the
SK-HD1500.
High-chroma detail
The High-chroma detail adjustments allow precise control of the detail
level in highly color-saturated portions of the picture such as the petals
of a rose or a colorful fabric.
Automatic vertical modulation shading adjustment
The SK-HD1500 assures that with any lens used, an even, chroma
response will be attained by the automatic vertical modulation shading
correction function. At the simple push of a button, this function
provides separate memory of lens’ modulation shading characteristics
to optimize the X1 and X2 lens extender positions.
Preset Masking
The preset masking function reproduce various image color such as
STANDARD(Hitachi standard)/ITU-709/SMPTE240M/SMPTE-WIDE/NTSC/EBU.
Chroma Saturation
In addition to the extensive colorimetry controls offered in the
SK-HD1500, the overall color saturation can be varied to achieve
“dramatic” or artistic “effects” .
