1-2 Operator's Manual LDK 20(S) - Studio Camera Introduction
The digital contour processing uses full amplitude
600% video RGB signals via an extended dynamic
range contour circuit. It enables the optimum levels of
contour control at highlights (in knee) and at sharp
edges, without first having to compress the highlight
signal. The dual auto skin tone contour circuitry
handles 360° of the colour vector.
Colorimetryisselectedbymeansof a variable 6-point
digital matrix or via preset matrices (1:1, EBU, RAI,
BBC and Skin).
Digital gamma circuits as well as providing a wide
rangeofstandardisedgamma curves also enablesoft
contrast in black scenes to be enhanced, together
with hard contrast and saturated colour in bright
scenes.
Digital contrast circuitry provides a black stretch
function for more detail in black areas and a black
press function for improving the contrast impression
by simulating the S-curve of film.
The LDK 20(S) camera uses Dynamic Pixel
Management (DPM). This new technology enables
the format of the sensors to be switched between 4:3
and 16:9 aspect ratios at the touch of a switch without
loss of horizontal resolution. The 1000 pixels per line
in both formats ensures that there is no loss in
horizontal viewing angle.
Another aspect of the 2/3" DPM sensors is that there
isnolossofverticalresolution between formats. They
haveahighlightcompression/dynamic rangeof600%
and a high linear sensitivity over all camera lens
apertures. The frame transfer technology ensures
that there is no lag nor smear. The 2/3-inch DPM
sensor has been designed so that vertical pixels are
addressable in groups of 3 or 4, for operating in 16:9
and4:3aspectratiosrespectively.Switchingfromthe
basic 4:3 sensor format to 16:9 gives no loss of
horizontal or vertical resolution. In fact, 1000 pixels
perlinewith both aspectratiosensureshigh resolution
in the red, green and blue camera channels.
General
LDK 20(S)
The HiRes Digital LDK 20(S) is a Studio camera
whichuses2/3" frametransfersensors. Theadvanced
HiRes Digital processing of the camera is based on
12-bit A/D converters, 14-bit DSP circuits and more
than 20-bit internal processing. Two DSPs combine
all major camera functions in the digital domain,
including knee, gamma, contour, matrix and colour
correction. A software programmable video path
enables the sequence of the matrix and gamma
function to be selected for precise colour matching of
different cameras.
TheIntelligentContinuousAutomaticsfacilityprovides
automatic control of black levels and black shading.
Each sensor has two lines of elements that are
protected from incoming light and therefore give a
true indication of black. The black reference signal
that they provide is used in the camera pre-processor
circuits to monitor temperature changes which, if not
corrected, would alter the black level. In this way
continuous automatic correction is applied without
operator intervention.
To emulate the softly limiting S-shaped transfer
characteristics of film, the TV camera's near linear
characteristicsarecompressedabove a certainpoint,
the knee. The pivoting knee circuit of the LDK 20(S)
camera adapts both the knee point and the
compression ratio according to the highlight content
of the picture. Significant highlights lower the knee
point to give more room for compression, while minor
highlights only affect the upper part of the transfer
characteristic. Signals below the knee point remain
unaffected. As a result, compression is only applied
where necessary and in proportion to the highlight,
and the pictures obtained have true film-like quality.
The 12-bit A/D processing of a 600% video level
assures high levels of accuracy for this advanced
dynamic handling.
DigitalTrueColourKneecircuitrymaintains thecorrect
hue for 600% compressed video highlights. With this
system colours are faithfully reproduced, even
overexposed skin tones.

Aspect ratio
The two aspect ratios that can be selected are the
conventional 4:3 and the widescreen 16:9. Because
of the dynamic pixel management (DPM) used in the
LDK 20(S) camera, there is no loss of either vertical
or horizontal resolution between these two modes.
Letterbox mode
When the conventional 4:3 mode is selected, there is
the additional choice of a letterbox format providing a
16:9, 16:10, or 16:11 blanked display. In the letterbox
formatthenumberof vertical linesisreducedbecause
oftheblanking.Thesignal,however,isfullycompatible
with the conventional 4:3 standard. The use of the
letterboxmode therefore,isdictatedbytherequirement
of providing a widescreen shot while remaining
compatible with the present 4:3 standard.
True widescreen mode
The widescreen 16:9 aspect ratio is selected when
there is a need for shots that can take full advantage
of the picture performance of EDTV (extended

Important Precautions
To ensure continual high performance from the
LDK 20(S)cameratakethefollowingprecautions into
consideration:
Avoid very damp places. If the
environment is wet or damp a
raincover must be used to protect it.
Do not subject the unit to severe
shocks or vibration.
Do not expose the camera to
extremes of temperature.
Donotleavetheunitin direct sunlight
or close to heating appliances for
extended periods.
Do not allow sunlight to shine into the
viewfinder.
Avoid extreme highlights as these
can cause various kinds of optical
reflections.
Warnings
If the LDK 20(S) is in a wet or damp environment, a
raincover must be used to protect it for personal
safety reasons (EN60065). The raincover LDK6988/
00 protects the camera according to safety specifica-
tion EN60529 up to level IPX2 (spraying water).

3-2 Operator's Manual LDK 20(S) - Studio Camera) Configurations
Basic Configurations
Stand-alone mode
The LDK 20(S) is a studio camera that can be used in
various configurations. The first configuration is the
stand-alone mode where the camera is connected to
a separate VTR. The LDK 20(S) camera is delivered
ready to operate in the remote mode. If the camera
has been switched to the local (stand-alone) mode,
follow the instructions to switch it back to the remote
mode in Section 2 of the installation manual. The
power supply is now provided to the camera via the
mains AC power supply at the right side of the
camera. The VTR is connected to the 26-pole
connector on the rear of the camera by means of the
optionalVTRcableLDL2110. The camera connector
provides SMPTE/EBU video component signals for
the VTR. The playback signal from the VTR can be
monitored in the viewfinder. The camera controls are
alloperatedlocallyonthe camera or via asingleOCP/
MCP connected to the data connector.
It is also possible to connect a VTR to the camera
when it is operating in the Triax (Remote) mode for
parallel recording. In this case power is supplied via
the Triax cable.

Single camera triax mode
The second configuration is the single camera Triax
(Remote)mode.Inthis case the camera is connected
to a base station via a Triax cable which can have a
maximum length of 2,400m (7,875 ft). The base
station provides the power supply for the camera via
the Triax cable. The base station receives its power
from the AC mains supply. The Triax cable carries R,
GandBvideosignals, two audio signalsandintercom
signals from the camera head to the base station. It
also carries teleprompter and external video signals,
and intercom signals from the base station to the
camera.
Remote control of the camera when used in the Triax
mode is achieved by a remote control panel of the
Series 9000 Control System. This can be an
operational control panel (OCP) connected to the
base station. The data communication between
camera and base station is carried over the Triax
cable. The control panel can also be connected
directly to the camera.

The third configuration is the multiple camera Triax

in the single camera Triax mode, however, in an
environment with up to fifteen cameras the data bus
is looped-through from base station to base station.
The OCPs used to control the cameras are also
connected to the same data bus. A master control
panel (MCP) can also be connected to this data bus
