Important information

Read these instructions carefully and retain them for future reference.

During installation and operation of this equipment, local building safety and fire protection
standards must be observed.

Before connecting the equipment to the power supply of the installation, verify the proper
functioning of the protective earth lead.

Whenever it is likely that safe operation is impaired, the apparatus must be made inoperative
and secured against any unintended operation. The appropriate servicing authority must then
be informed. For example, safety is likely to be impaired if the apparatus fails to perform the
intended function or shows visible damage.

Any changes or modifications not expressly approved in this manual could void your authority
to operate this equipment.

Cautions and Warnings

Read and comply with the warning and caution notices that appear in the manual.

• Warnings indicate danger that requires correct procedures or practices to prevent death or
injury to personnel.

• Cautions indicate procedures or practices that should be followed to prevent damage or
destruction to equipment or property.

8 LDK 8000 HDTV camera system User’s Guide (v3.0)

Warnings

To prevent fire or shock hazard, do not expose the unit to rain or moisture. If the unit is in a wet
or damp environment, a rain cover must be used to protect it for personal safety reasons
(EN60065). The rain cover supplied with the unit protects it according to safety specification
EN60529 up to level IPX2 (spraying water).

To avoid electrical shock, do not remove covers or panels. Refer servicing to qualified
personnel only.

In case of an emergency ensure that the power is disconnected.

Use only fuses of the type and rating specified.

Connect the product only to a power source with the specified voltage rating.

The Base Station must always be connected to protective earth. Do not interrupt the
protection conductor inside or outside the unit. Do not disconnect the protective earth
terminal. Intentional interruption is prohibited and is likely to make the unit dangerous.

To prevent risk of overheating, ventilate the units correctly.

For safety reasons the Base Station must be mounted in a 19-inch rack which has safety covers
according to IEC65. When two Base Stations are mounted above each other, the minimum
distance between them must be 50mm or the rack must be force-air cooled.

LDK 8000 HDTV camera system User’s Guide (v3.0) 9

Triax cable systems

Only connect a Triax cable from the same LDK camera family to the unit.

Do not allow system earth currents to exceed 1.5A in the outer shield of the Triax cable or 0.2A
in other cable shields.

To avoid excessive earth currents in a Triax system, galvanically separate the power earth
connection of equipment connected to the camera from the camera earth.

It is strictly prohibited to short circuit the inner and outer shields of a Triax cable used to
connect a camera to a base station.

Galvanic separation

Because of the nature of Triax systems, with long distances between camera and Base
Station, the risk of earth currents flowing is greater. These earth currents can result in damage
to the equipment.

For example, a monitor connected directly to the CVBS output of the camera is powered
locally. The earthing point of the monitor’s power supply can be at a different potential with
respect to the earthing point of the Base Station. If the power earth of the monitor is also the
video earth, then this earth potential is transferred to the camera via the shield of the BNC
connector. The difference in earth potential between the camera and the Base Station results
in an earth current in the Triax system.

To prevent earth currents from flowing in the Triax system, we recommend galvanic separation
of earthed equipment connected to the camera. This separation can be achieved by using an
isolation transformer between the local power outlet and the equipment connected to the
camera. Alternatively, use equipment that has a double insulation and therefore does not
require an earth connection.

10 LDK 8000 HDTV camera system User’s Guide (v3.0)

Base Station earthing

The rear of the unit has two separate screw terminals for protective earth (PE) and video
earth (VE). These are normally connected by a metal strap.

The protective earth terminal is internally connected to the protective earth conductor of the
power cable. In normal circumstances the connection between the protective earth and the
video earth should not be broken. If required, the central earth connection wire of the studio
can be connected to terminal PE in accordance with VDE regulation 0800/part2.

Only if the studio (or OB van) is equipped with separate protective and video earth systems
may the metal strap be removed. Under these circumstances the video earth terminal must be
connected to the central functional earth potential (video earth) of the studio. This earth
potential should have functional protective and noiseless earth (FPE) qualities as stated in the
VDE regulation 0800/part2. A low impedance interconnection of both earth conductors must
be provided at the central studio earthing point.

Introduction

1.1 Technology

Chapter 1 - Introduction

The LDK 8000 is a high definition multi-standard, multi-format digital camera head using
three 2/3-inch HD-DPM
adapter for a flexible camera that is equally at home in the studio or out on location.

The SportCam version can capture true progressive HD images, natively, in multiple formats
and frame rates. It supports 2x high-speed acquisition at either 100

1.1. 1 HD sensors

The camera head uses HD-DPM+™ CCD sensors which offer superior performance and
ultimate flexibility. Native wide screen pictures in the high-definition formats 1080i, 1080p
(WorldCam) and 720p are produced at the touch of a button. This unique native multi-format
capability is realized with innovative 9.2 million pixel 2/3" CCD sensors. These allow vertically
grouping of different numbers of pixels on the sensors themselves. There is no need for HDTV
format conversion during digital signal processing which would lead to quality degradation.

These sensors have a high dynamic range and high linear sensitivity across all camera lens
apertures. They are based on Frame Transfer technology, which ensures that there is neither
lag nor smear.

1.1. 2 Digital processing

The advanced digital processing of the camera is based on 14-bit A/D converters and more
than 22-bit internal processing. All major camera functions are processed in the digital
domain, including knee, gamma, detail, matrix and colour correction.

+

™ sensors. The camera head can be combined with the TriaxHD

Hz or 119.88 Hz.

The intelligent continuous automatics facility provides automatic control of black levels and
black shading. Each sensor provides black reference signals that are used to monitor
temperature changes. This means that continuous automatic correction is applied without
operator intervention.

The digital detail processing uses full amplitude video RGB signals via an extended dynamic
range detail circuit. Colorimetry is selected by means of a variable 6-point digital matrix or via
preset matrices. Digital gamma circuits provide a wide range of standardised gamma curves
and enable soft contrast in black scenes to be enhanced, together with hard contrast and
saturated colour in bright scenes. The matrix and gamma sequence is software programmable
for precise colour matching.

LDK 8000 HDTV camera system User’s Guide (v3.0) 13

Chapter 1 - Introduction

1.1. 3 Film-like characteristics

The pivoting knee circuit adapts both the knee point and the compression ratio according to
the highlight content of the picture to emulate the softly limiting S-shaped transfer
characteristics of film. Digital True Colour Knee circuitry maintains the correct hue for
compressed highlights, reproducing colours faithfully, even overexposed skin tones.

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.

1.1. 4 Focus assist

With HDTV, focusing is even more critical than before. The LDK 8000 has special patented
focusing aids. A unique viewfinder zoom function enlarges the viewfinder image instantly
with a simple press-button action, thus providing improved means for focusing. A patented
crawler circuitry adds motion in the viewfinder to objects in sharp focus.

1.1. 5 Standard version

The Standard version supports 1080i/720p HD formats in 50, and 59.94 Hz, and
simultaneously provides high-quality SDTV outputs in either 50 Hz or 59.94 Hz.

The following acquisition formats are available for the Standard version:

– 1080i at 59.94 Hz

– 1080i at 50 Hz

– 720p at 59.94 Hz

– 720p at 50Hz

1.1. 6 SportCam version

The SportCam version provides, in addition to the Standard version formats, high-speed
acquisition formats that are output as a two-phase signal from the high-speed base station.

The following acquisition formats are available for the SportCam version:

– 1080i at 59.94 Hz

– 1080i at 119.88 Hz

– 1080i at 50 Hz

1.1. 7 WorldCam version

The WorldCam version provides, in addition to the Standard version formats, digital
cinematography formats in 1080p and 720p, which give an impression of motion comparable
to film cameras running at identical speeds.

The WorldCam also provides convenient built-in frame-rate conversions for easy connection
to existing HD peripherals, offering possibilities for cost-effective monitoring and recording
combined with the motion portrayal of film cameras. The 1080p format at 23.98 Hz, for
example, can be converted using 3:2 pull-down to 1080i at 59.94 Hz right inside the camera.

The following acquisition formats are available for the WorldCam version:

– 1080i at 59.94 Hz

– 1080i at 50 Hz

1.1. 8 Advanced TriaxHD features

TriaxHD, which is a further development of the Emmy Award winning triax transmission
system, makes the camera compatible with industry standard triax cables. This allows the
reuse of existing, reliable and valuable cable inventories.

TriaxHD allows video transmission and remote control of cameras up to a distance of 1,200 m
(4,000 ft.) and beyond, using industry standard 14 mm triax cables. It is based on 30MHz full­bandwidth 4:2:2 transmission (Y/Cr/Cb components).

The double side band modulation technique used in combination with Y/Cr/Cb transmission
ensures linearity, resolution and an optimal signal-to-noise ratio over the maximum cable
length. Bandwidth efficient channel combining and equalization techniques minimize cross­talk and interference. Teleprompter and viewfinder signals maintain high performance with
relatively long cable lengths.

The communication facilities provide for two-wire or four-wire high quality intercom signals.
Full camera control is provided via a C2IP Ethernet-based control network.

The TriaxHD adapter is equipped with a rotary triax connector which provides freedom of
movement during portable use of the camera and protects the connector from being
damaged in near-floor conditions.

3.1 TriaxHD mode

A camera head with the LDK 5860 TriaxHD adapter is connected to a TriaxHD Base Station
using a Triax cable. The maximum length of cable that can be used without significant
degradation of the video signal is 1,200 m (4,000 ft.) for a 14 mm Triax cable.

The power supply is applied to the Base Station and via the Triax cable to the camera. An
OCP 400 operational control panel can be connected directly to the Base Station using a cross­over Ethernet cable.
