1.3 Description
General Information on D-ENG (Digital Electronic News Gathering)
The introduction of the DVB standard established the basis for digital broadcast video
transmission making efficient use of the available bandwidth. Powerful compression
algorithms allow a reduction in the amount of data to be transferred, while
maintaining the high quality standards for video and audio signals used in broad
casting applications. New modulation techniques and error correction algorithms
ensure a secure signal transmission even when the transmission conditions are poor.
The DVB T standard was established for terrestrial digital TV broadcasting, in
particular considering the difficult conditions of radio transmission. The highly efficient
OFDM multicarrier modulation procedure enables transmission without interference
even under multipath propagation conditions occurring with non directional
transmission or reception. Practical experience soon has proved that the DVB T
standard guarantees ruggedness of transmission to an extent even allowing mobile
reception.
Increasing miniaturization, in particular of MPEG encoders and OFDM modulators,
enables using the DVB T standard for mobile portable transmission systems.
Previous analog FM systems were adversely affected by signal reflections directly
resulting in video and audio interferences. Such effects do not occur when the digital
ENG system (D ENG) is deployed. Even mobile transmission from moving vehicles or
the use of omni directional antennas on the transmitting or receiving side does not
impair the picture or sound quality at all, opening a completely new range of
applications in TV production and news gathering.
Video Inputs
The CT6020HD accepts only HDSDI and SDI information at the input:
•SDI BNC(f)
OFDM (Orthogonal Frequenc Division Multiplex) Modulator
The digital data signal for wireless transmission is processed by the OFDM Modulator
and following IQ Modulator. The OFDM modulation procedure has a major impact on
the transmission properties and was specifically developed for terrestrial radio
transmission.
User interface
The integrated Multifunctional Display allows easy configuration of the device. The
current Software and firmware version can also be displayed.
Linear Power Amplifier
The linear power amplifier amplifies the output signal of the Modulator to an output of
about 200 mW (+23 dBm). The output port is located on top of the device.

2. Installing the Equipment
2.1 Safet instructions
Warning
The regulations of VDE0100 must be observed for
installation and operation of the unit.
Caution
•Establish all other connections before starting the unit by
connecting it to 12VDC. Essential, a valid video signal must be
connected to the desired input before power on the CT6020HD.
•When you connect the CT6020HD as described in the following
sections, make sure that the "Caution" instructions given there
are observed.
•Make sure that there is sufficient air circulation to ensure
adequate cooling of the unit.
External forced ventilation may be required if the unit is installed
in a rack or cabinet.

RF Connector
The RF output signal of the Low Power Amplifier is fed out at the N(f) connector on
top of the unit.
The CT6020HD provides RF output of about 200 mW (+23dBm).
Connecting Signal Sources
The Video signal supplied by the camera has to be applied to the HDSDI BNC(f)
connector of the transmitter.
The Audio signal supplied by the camera has to be applied to the Audio in 5pol Lemo
connector of the transmitter.
Connecting the RF Output
An omni directional antenna with N(m) connector can be directly mounted at the RF
out socket.
Connecting the UHF Data Input (optional)
An UHF antenna with SMA(m) connector can be directly mounted at the UHF in
socket.

Connecting the 12VDC Suppl Voltage
Caution
When using a battery or power pack, make sure that the minimum
supply current is at least 3A and the output voltage matches the
input voltage range of the CT6020HD.
Failure to comply with these requirements ma cause fatal
damage to the battery/power pack and/or CT6020HD.
Batter Powered Operation of the CT6020HD
Many types of batteries are available on the market and we tried to support the best
ones.
2.3 Shut-Down
Caution
To shut down the unit, first disconnect it from the 12VDC supply
voltage.
After disconnection from the supply voltage by removing the battery or disconnecting
the 12VDC supply cable, the other connecting cables can be removed from the unit.

3.4 Framerate (3)
After setting the resolution (1080p/1080i/720p/SD) it is important to set the correct
corresponding frame rate.
Please check, at all costs, which HD output signal, which resolution the video signal
has and which frame rate (1080p/1080i/720p) the camera is set to. A list of the
resolution and corresponding frame rates is added below.
The following Frame rates are available:
•23,98 Hz (1080p)
•24 Hz (1080p)
•24 PsF (1080p)
•50 Hz (1080i/720p/SD)
•59,94 Hz (1080i/720p/SD)
•60 Hz (1080i/720p/SD)
To edit the frame rate sub menu press Enter Button for 2 seconds.
Use the Up and Down Buttons for navigation and select the desired frame rate by
pressing the Enter Button.
To exit this submenu press Enter Button.
Note
With PsF, a progressive frame is sliced into two "segments", with
the odd lines in one segment and the even lines in the other
segment. This allows for a progressive picture to be processed
through the same electronic circuitry that is used to store, process
and route interlaced video. Technically, progressive segments are
equivalent to interlaced fields, but unlike native interlaced video,
there is no motion between the two fields to make up the video
frame, both fields represent the same instant in time.
