About this Manual
This Operator's Manual is part of a complete
documentation set for the camera system which also
includes an Installation and Service Manual.
Purpose of this manual
The purpose of this manual is to present a detailed
descriptionof how to operate the LDK23HS mkIIEFP
-Studio Camera. Itprovidestheinformation necessary
to use the camera system in different configurations
and with various attachments. With this manual it is
possible to discover the operating features of the
camera system and so use it to its full potential. The
manual should be used together with the camera
system to explore and learn about the many
sophisticated control functions available.
Intendedaudience
ThisOperator'sManual can be used byinexperienced
cameraoperatorswhoare newtoThomsonMultimedia
Broadcast Solutions cameras as well as those who
have previous experience of operating cameras. The
guide is so designed that it can be used as an
introduction to those who are new to the camera
system, as a simple procedural guide to those who
wish to setup and start shooting immediately, and as
areference worktobeconsulted asrequiredduringthe
long life of the camera system.

1-2 Operator's Manual LDK 23HS mkII - HS Camera System Introduction
Technology
The LDK 23HS mkII is a lightweight EFP/Studio high
speed camera system which uses 2/3" frame transfer
sensors with Dynamic Pixel Management (DPM).
Super Slow Motion
Unique live slow motion capability. The LDK 23 HS
mkII scans at three time the normal rate. Instead of
scanningat50 HzforPALand60 Hz forNTSCtheLDK
23HS mkII scans at 150 Hz for PAL and 180 Hz for
NTSC.
Various preset settings for artificial light conditions
ensure a slow motion picture without pulsing light
effects.
Sensortechnique
Frame Transfer Dynamic Pixel Management allows
the format of the sensors to be switched between 4:3
and 16:9 aspect ratio 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
horizontalviewingangle.
Another aspect of the 2/3" DPM sensors is that there
isnolossofvertical resolution between formats. They
haveahighlightcompression/dynamic range of 400%
and a high linear sensitivity over all camera lens
apertures.Theframe transfer technologyensuresthat
there is no lag nor smear.
TheIntelligent ContinuousAutomaticsfacilityprovides
automatic control of black levels and black shading.
Each DPM sensor has two lines of sensor 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
preprocessorcircuitsto monitor temperature changes
which, if not corrected, would alter the black level. In
this way continuous automatic correction is applied
withoutoperatorintervention.
Film-likecharacteristics
To achieve film-like quality it is necessary to emulate
the softly limiting S-shaped transfer characteristics of
film. This is done by compressing the TV camera's
near linear characteristics above a certain point, the
knee. The pivoting knee circuit of the LDK 23HS mkII
camera system adapts both the knee point and the
compressionratioaccordingto 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
wherenecessary and inproportiontothe highlight,and
the pictures obtained have true film-like quality.
AdvancedTriaxFeatures
The Triax system allows remote control of camera up
to a distance of 800 meters (1000 meter with minor
performance degration). The Triax system uses YUV
transmission.
The communication facilities provide for two-wire or
four-wire high quality intercom signals.
The LDK 23 HS mkII is compatible with the existing
ThomsonMultimedia BroadcastSolutionsSeries9000
UniversalCameraControlsystem.Basestationoutputs
include triple and normal scan serial digital video
signals.
SuperXPander
The optional LDK 4482 SuperXpander enables the
camera to be used with large lenses so extending the
camera's use in studio and EFP situations.

Important Precautions
To ensure continual high performance from the LDK
23HSmkII camera take the followingprecautions into
consideration:
Avoid very damp places. If the
environment is wet or damp a
raincovermustbeused to protect it.
Do not subject the unit to severe
shocks or vibration.
Do not expose the camera to
extremes of temperature.
Do not leave the unit in direct
sunlight or close to heating
appliances for extended periods.
Do not allow sunlight to shine into
theviewfinder.
Avoid extreme highlights as these
can cause various kinds of optical
reflections.
Warnings
If the LDK 23HS mkII 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 IPX3 (spraying water).

Assembling the Units Operator's Manual LDK 23HS mkII - HS Camera System 2-1
Section 2 provides information on the physical assembly of the camera system and on how

Transport Case
It is important to protect your camera against damage
when transporting it. To do this, a transport case is
available for the camera, lens, viewfinder and some
accessories.
The camera is packed in the transport case as shown
in the figure above. This ensures that the camera is
notdamagedduringtransport.Donotforgettosecure
the straps around the items to keep them in place.
