2.3 Description
The COFDM AV module HDCT 460 AV, in the following called digital module, has
a COFDM AV converter which simultaneously converts four COFDM modulated
channels into AV signals using two DVB-T tuners.
The digita l module has two DVB-T inputs. Via the AV interface, the decoded
video and audio signals are fed to the corresponding modulator module. From
there, they are fed to the HF output collector of the head-end station, through
which the level of the output signal can be adjusted via the software in the
head-end station.
The channel strips “A” “B”, “C” and “D” can be individually programmed. This
means it is possible to select up to 4 channels out of two data streams. The fol-
lowing table shows the allocation of the selectable number of channels to the
tuners:
Tuner “A” Tuner “D”
Number of
channels
31
22
For example, if three channels from tuner “A” will be used, one channel from
tuner “D” can be used. If two channels from tuner “A” will be used, two chan-
nels from tuner “D” can also be used.
Signal transfer principle:
The operating software of the digital module can be updated via the 9-
pin SUB-D socket on the control unit of the head-end station using a PC or
notebook and the Software “BE-Flash”. You can find the current operating
software on the website “www.gss.tv”.
This digital module is designed exclusively for use in the STC 160 head-end
station.

3 Installation
Caution
Before installing or changing a module, switch off the head-end station or
unplug the power cable from the mains power socket.
Take precautions to prevent electrostatic discharge when working on the
device!
• Open the housing of the head-end station according to the instructions in
the STC 160 assembly instructions.
3.1 Installing the digital module
Caution
– Always position modules which belong together next to each other. The
digital module must be installed to the left of the modulator module.
– Insert the digital module in a long numbered groove in front of a contact
strip on the board at the rear wall of the housing.
The shorter not numbered grooves without a contact strip on the board
at the rear wall of the housing are for add-on modules only.

Note:
Slots 1 (digital module) and 2 (modulator module) are shown in the illustra-
tion. The open slots in between (without a contact strip on the board at the
rear wall of the housing) are intended for add-on modules.
• Insert the digital module in grooves Aand Bof an open slot (with contact
strip on the board at the rear wall of the housing) next to the associated
modulator module.
• Gently slide the digital module into the head-end station and ensure that
it makes contact with the contact strip on the board at the rear wall of the
housing.

activated.
Setting the input channel
Note:
–
If “– –” appears in the second line of the display, there is no
input signal present. Check the configuration of the antenna
system and head-end station.
– If the received signal is all right, “ OK ” is displayed.
• Set the desired input channel by pressing the but-
tons repeatedly or permanently.
Notes:
– Beside the input channel set the corresponding fre-
quency is displayed.
– The quality of the data stream received is indicated
by two status LEDs:

Setting the hierarchical modulation
In order to attain with less field strength a greater range for
broadcasters, with DVB-T so-called “hierarchical modula-
tion” is used. In this process, several data streams are modu-
lated onto a DVB-T data stream using “Quadrature Amplitude
Modulation” (QAM). The robust “High Priority” data stream
(HP) with a lower data rate is modulated onto the more
sensitive “Low Priority” data stream, which possesses a
higher data rate. In good reception conditions, the receivers
can receive both data streams; in poorer reception condi-
tions, only the “HP” portion. Several receivers can be sup-
plied simultaneously with various services via one channel.
• By pressing , set to “high “ or “low “
(not relevant in the case of standard modulation).
• Press the Mbutton.
—> The “Automatic channel search / station filter” –
e.g. “Bx 1A 01/04 + TV” menu is activated.

Automatic channel search / station filter
In this menu, select the channel from the data stream that is
to be made available through this channel strip.
If the error message “no transponder” appears, no input
signal is present. In this case, you should check the previ-
ous settings as well as the configuration of the receiving
system.
If the “scanning ...” message appears on the display, the
table of received channels is being read. Please wait until
this process is finished.
As soon as the automatic channel search has found all of the
TV or radio stations, the corresponding data appears in the
display of the head-end station.
Meaning of the indicators shown in this example:
“01/04” – The first of a total of 4 TV channels is being
shown or has been activated.
“+” – The audio stream for the current TV channel is
available in several languages.
“TV” –The data on the display corresponds to a TV
channel.
“arte” – Station name
Other possible indicators:
“RA” – The data on the display corresponds to a
radio station.
“ * “ – A star indicates that this TV or radio station is
encoded.

Notes:
—> For radio stations, the back ground of the screen of the
connected TV or test receiver is darkened.
—> If a service number (e.g. “SERVICE 131”) appears
instead of “TV” or “RA”, this indicates that an un-
named station or an undefined data stream is being
received.
• Select the desired TV or radio station with the
buttons.
• Press the Mbutton.
—> If the selected channel is broadcast with two or more
audio streams, the “Selecting the audio stream for a
TV channel” – “AUDIO” menu will appear.
Otherwise the “Setting the volume level” – “AUDIO
Level” menu is activated (see page 21).
Selecting the audio stream for a TV channel
This menu only appears if the selected channel is broad-
cast with two or more audio streams (languages). In this
menu, select the desired audio stream from the transport
stream.
• Use the buttons to select the audio stream you want.
—> In the example the audio stream “01” of two available
audio streams is selected.
• Press the Mbutton.
—> The “Setting the volume level” – “AUDIO Level” menu
is activated.
