2.4 de s C rip t i o n
The Head-end Digital Transmodulator QAM "HDMA 784 C ASI", in the fol-
lowing called QAM module converts two DVB-S/DVB-S2 (also 16/32 APSK)
modulated data streams into four DVB-C (QAM) modulated data streams. The
QAM module has two SAT-IF inputs, one ASI input and one HF output.

The QAM module is equipped with four channel strips ("A" … "D"). For each
channel strip tuner or ASI input can be selected. The channel strips consist of the
digital SAT tuners, the digital signal processing units and an output converter.
For channel strips A/B resp. C/D adjacent channel setting is fixed.
Using adequate CA modules scrambled channels can be descrambled via
channel strips "A" and "C".
Four LEDs indicate if the respective channel strip is
switched on (LED illuminates) or off, and also provide
an indication of the signal quality based on their
colour.
The integrated TPS module (Transport Stream
Processing) processes the data from the demodu-
Status LEDs
Channel strip A

lated transport streams.
Channel as well as frequency setting is possi-
ble for modulators "A" and "C". The modulators
"B" and "D" work at a spacing of + 8 MHz to
modulators"A" and "C". Herein only frequency setting (frequency spacing of
channel strips "A <–> B" and "C <–> D") is possible.
The QAM modulated HF output signals are sent through the HF output of the
QAM module
to the output collector of the head-end station.
When the head-end station is switched on, the two-line LC display shows the
"SETUP" menu and the software version of the control unit. The head-end station output level can be adjusted in this menu.
The control of the module takes place via the control unit of the
tion. To operate the
QAM module
the software version of the control unit (headend station) must be "V 10" or higher. The operating software of the
module and the
head-end station can be updated using a PC and the software
head-end sta-
QAM
"BE-Flash" via the 9-pin D-SUB socket on the head-end station. You can find
the current operating software for the head-end station
the software "BE-Flash"
and the current assembly instructions
and the QAM module,
on the website
"www.gss.de/en".
The
QAM module
is designed exclusively for use in the STC 160 head-end
station.

2.5 ho w t h e tps modul e wo r ks
After decoding the satellite signals, the demodulated data streams can be
accessed via the integrated TPS module. These data streams, also called transport streams, contain several stations with all their components (video, audio,
data and service information), which can be changed using the TPS module.
statio n f i lte r
Individual stations can be deleted. This reduces the data rate and, conse-
quently, the output data rate.
Cha n g i ng th e trans p o r t s trea m a n d orgnet-id
The transport stream ID can be changed. If the stations of a transponder are
split into the transport streams of different channel strips, a new identification
must be allocated to the "new" transport streams to realise the channel search
of the settop boxes connected without mistakes.
If the ORGNET-ID is changed a new NIT must be generated.
Cha n g i ng th e nit
The transport stream contains data in the form of tables which the receivers
evaluate and require for convenient use. The TPS module can adjust the "Network Information Table" (NIT) to accommodate the new stations output data
(incl. LCN). The "NIT" contains data which is required by the set-top boxes
connected to the cable network for the automatic search feature.
2.6 ex p l anation of th e t e r m "sym bol r ate"
Modulation schemes such as QPSK and QAM transmit multiple bits simultane-
ously. These are referred to as symbols. In addition to the user data flow which
transmits video and audio information, error correction bits are transferred.
The FEC number states the ratio of user bits to the complete transmitted bits.
The output symbol rate is calculated as follows:
256-QAM: SR (A) = FEC x 1/4 x SR (E)
128-QAM: SR (A) = FEC x 2/7 x SR (E)
64-QAM: SR (A) = FEC x 1/3 x SR (E)
32-QAM: SR (A) = FEC x 2/5 x SR (E)
16-QAM: SR (A) = FEC x 1/2 x SR (E)
4-QAM: SR (A) = FEC x 1/1 x SR (E)
- 7 - HDMA 784 C ASI
Page 8
Example:
Output symbol rate SR (A) 64-QAM,
Input symbol rate SR (E) = 27,500
kSymb/s
FEC= 3/4,
SR (A)
tr an s p o nde r w i t h a v ery low sym bol r ate (sCpC stat i o n)
The extremely low data rate means that the output symbol rate is very low. If
de f i n ed symbol r ates
Some cable operators specify a fixed symbol rate (e.g. 6,900 kSymb/s).
= 3/4 x 1/3 x 27,500

"FEC = 3/4".
there are reception problems with different digital receivers, set output symbol
rate to a higher value.

– Ensure the head-end station is mounted so it will not be able to vibrate.
Avoid, for example, mounting the head-end station onto a lift shaft or any
other wall or floor construction that vibrates in a similar way.
– Before installing or changing a module, switch off the head-end station or
unplug the power cable from the mains power socket.
– Take measures to protect against ESD!
• Open the housing of the head-end station in accordance with the assembly
instructions for the STC 160.

3.1 retrofit t i n g a Ca mod u l e
The cassette is equipped with two common interfaces. This allows you to con-
nect two CA modules for various scrambling systems and service providers.
Scrambled channels can only be descrambled with a CA module suitable for
the scrambling system and the corresponding smart card. The smart card contains all the information for authorisation, descrambling and subscription.
– Check with the distributor or manufacturer of the CA modules to be used
to ensure that they are suitable for descrambling several channels.
– The hardware and software of this cassette have been thoroughly prepared
and tested.
– Any changes made by programme provider to the structures in the pro-
gramme data might impair or even prevent this function.
– When working with the CA modules, please read the corresponding oper-
ating manuals from the respective providers.
• Insert the smart card
1 into the CA module 2 so that the chip 3
on the
smart card faces the thicker side (top) of the CA module (fig. 1).
• Push the CA module 2 without canting into the guide rails 4 of the common interface 5 according to the following picture and contact it to the
common interface.

3.2 installing t h e Qam mod u l e
–
Check that the plug contacts of the CA module are tightly seated in the
terminal strips on the
common
interface of the
QAM
module and make
sure there is reliable contact.
– When installing a module, make sure that it is inserted in one of the long,
numbered grooves in front of the contact strip on the board at the rear wall
of the housing.
– The shorter, non-numbered grooves without a contact strip on the board at
the rear wall of the housing are for add-on modules only.
• Open the housing of the head-end station in accordance with the assembly
instructions for the STC 160.
• Open the locking device 1 in the direction of the arrow (fig. 2).

Cha n n el / freQuen C y
In this menu you can adjust the output channel (only at modulator A and C) or
the output frequency of the respective modulator.
—> The QAM signal is normally transmitted with a bandwidth of 8 MHz.
This means that you can only use the existing channel grid in the
range of channels C21…C69 (frequency grid 8 MHz).
The CCIR channel grid is 7 MHz in the range of the lower frequency
bands (channels C5 … C12, S2…S20). If 8 MHz QAM signal
packages are transmitted in these channel ranges, this will result in
interference (overlapping) and transmission problems.
For programming in these channel ranges and in the frequency rang-
es below them, we recommend starting with frequency 306 MHz
going back in steps of 8 MHz (see frequency table on page 39).
Please note thereby that many receivers cannot receive the channel
ranges S21…S41 (306 … 466 MHz).
