2.4 Description
The twin transmodulator cassette is a QPSK-converter, which converts all stations modulated according to DVB-S /
ed cable signals.
The
cassette
has two digital SAT IF inputs and an HF output. It
DVB-S2
standard into two QAM-modulat-
is equipped with two channel strips (“A” and “B”). The channel strips consist of
the digital tuners, the digital signal preparation units and the output converter.
The channel strips are indicated in the head-end station display with “Bx …A”
and “Bx …B”. Using an adequate CA module encoded channels can be decoded via channel strip “A”. The control of the cassette takes place via the control
unit of the head-end sta
tion.
Two 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. Additionally the quality of the data stream received is displayed
(“CN…”).
The integrated TPS module (Transport Stream Processing) processes the data
from the demodulated transport streams. This enables service information (NIT –
Network Information Table) to be changed, data rates to be increased (stuffing)
and for individual stations to be deleted from the transport stream (thus optimising bandwidth for the other stations being transmitted).
The HF output signals are sent through the HF output of the
cassette
to the output
collector. The common output level of the channel strips can be set at the output
collector.
When the head-end station is switched on, the two-line LC display shows the
software version of the control unit.
To operate this cassette the software version of the control unit must be “V 37”
or higher. You can find the current operating software for the control unit and
the cassette, the software “BE-Flash”
and the current assembly instructions
website “www.gss.tv”.
The
cassette is
designed for use in the following head-end stations:
– STC 1200
– STC 316
– STR 19-8
on the
- 6 -
- 7 -
2.5 Software query
Control unit
If necessary, you can activate the indication of the software version of the control unit manually:
• Press any two keys on the control unit of the head-end station simultaneously
until the display goes dark and
the software version, e.g. “
V 37
” appears.
2.6 How the TPS module works
After decoding QPSK- or 8PSK-modulated signals, the demodulated data stream
can be accessed via the integrated TPS module. This data stream, also called
transport stream, contains several stations in all their components (video, audio,
data and service information), which can be changed using the TPS module.
The individual functions
Station filter
Individual stations can be deleted. This reduces the data rate and, consequently,
the output symbol rate required.
Stuffing
The transport stream is padded using what is known as zero data. This ensures
a steady and constant output symbol rate.
Changing the 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 station data. The “NIT”
contains data which is required by the set-top box for the automatic search
feature.

2.7 Explanation of the term “symbol rate”
Modulation schemes such as QPSK and QAM transmit multiple bits simultaneously. 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:
1
256-QAM: SR (A) = FEC x
/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)
Example:
Output symbol rate 64-QAM,
Input symbol rate SR (E) = 27,500
SR (A)
= 3/4 x 1/3 x 27,500
SR (A)
=
6,875 kSymb/s
FEC= 3/4,
kSymb/s
kSymb/s
Note:
If no “FEC” is stated in the station lists, it can be assumed to be
“FEC = 3/4”.
Reception from a transponder with a very low symbol rate
(SCPC station)
The extremely low data rate means that the output symbol rate is very low. If
there are reception problems with different digital receivers, set output symbol
rate to a higher value.
Defined symbol rates
Some cable operators specify a fixed symbol rate (e.g. 6,900 kSymb/s).

2.8 Bandwidth-efficient assignment of cable channels with low bandwidths
(SelecPlex®)
Channels with low bandwidths are the result of filtering out stations which are
not required. These “narrow” channels can then be arranged in one channel to
save space. To do this, activate the “Setting the output frequency” menu (assignment outside the official channel raster).
—> The required bandwidth (in kHz) is roughly equal to the symbol rate
(kSymb/s) plus 20% in MHz.

3.4 Retrofitting a CA module
The cassette is equipped with a common interface. It allows you to connect
a CA module for various encryption systems and service providers. Encoded
channels can only be decoded with a CA module suitable for the encoding
system and the corresponding smart card. The smart card contains all the information for authorisation, decoding and subscription.
Caution
– Check with the distributor or manufacturer of the CA module to be
used to ensure that it is suitable for decoding several channels.
– The hardware and software of this cassette have been thoroughly pre-
pared and tested.
– Any changes made by program vendors to the structures in the program
data might impair or even prevent this function.
– When working with the CA module, please read the corresponding op-
erating manual from the respective provider.
• Insert the smart card into the CA module so that the chip on the smart card
faces the thicker side (top) of the CA module.
• Insert the CA module into the slot
module facing the top side of the cassette.
• Push the CA module without canting into the guide rails of the common interface slot and contact it to the common interface.

In this menu, you can choose the channel or frequen cy setting
for the adjustment of the HF output. The channel setting covers the range of channels S21 … C69, the frequency setting
covers the range from 42.0 MHz to 860.0 MHz.
The QAM signal is normally transmitted with a bandwidth of
8 MHz. This means that you can only use the channel centre
frequency of the existing channel raster in the range of channels S21 … C69 (frequency raster 8 MHz). The CCIR channel raster is 7 MHz in the range of the lower frequency bands
(channels C2 … S20). Therefore the frequency setting is used
here. If one uses the existing channel raster of 7 MHz in these
channel ranges, this will result in interference (overlapping)
with the 8 MHz QAM signal packages, thus causing transmission problems.
For programming in these channel ranges and in the frequency ranges below them, we recommend starting with channel
S21 / 306 MHz going back in steps of 8 MHz, or reducing
