2.4 Description

The twin transmodulator cassette is a converter, which converts all stations
modulated according to DVB-S /

DVB-S2

standard into two COFDM-modulated

signals according to DIN EN 300744 for feeding into a cable network.

The

cas-

sette

has two digital SAT IF inputs and an HF output. Additionally it is equipped
with an ASI input and an ASI output (ASI – Asynchronous Serial Interface acc.
DIN EN 50083-9).
The transport stream fed via the ASI socket can be inserted into the transport
streams of the receiving stages via the TPS module. The signal path is set in the
menu items input signal path

“INROUTE” and output signal path ”OUTROUTE”

.

Transport stream 1 is made available via modulator “A”, transport stream 2 via
the ASI output and the transport stream from the ASI input “TS ASI” via modula­tor “B” (MB).

2.4.3 General

The cassette 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 station.
Two LEDs provide an indication of the SAT IF input signal quality based on
their colour and indicate if the respective channel strip is switched on (LED
illuminates) or off. Additionally the quality of the transport stream received is
displayed (“CN…”). The integrated TPS module (Transport Stream Processing)
processes the data of the transport streams.
The COFDM modulated 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. Additionally a transport stream is made avail­able via the ASI output dependent on the signal path set.
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 38” 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 on the website “www.gss.tv”.
The cassette is designed for use in the following head-end stations:
– STC 1200
– STC 316
– STR 19-8

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 38” appears.

2.6 How the TPS module works

After decoding QPSK- or 8PSK-modulated signals, the demodulated data streams
and the data stream fed via the ASI socket can be accessed via the integrated
TPS module. These data streams, also called transport streams, contain 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. Additionally stations of the different transport streams
can be assembled to a new transport stream.

Stuffing

The transport stream is padded using what is known as zero data. This ensures
a steady and constant output data 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 boxes connected to the cable
network for the automatic search feature.

Changing the operator ID (CAT)

Some network operators transmit an operator ID in the data stream (e.g. visAvi­sion). By changing the CAT the operator ID can be adjusted to the current
demands.

3 Assembly

3.1 Installing the cassette

– 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 cassette unplug the power cable from the

mains power socket.

• Remove the fastening screws

1 of an unoccupied slot from the bracket of the

head-end station.

• Insert the cassette in this slot and push it into the housing.

• Align the cassette and apply slight pressure to connect it to the connections of
the board and the HF bus bar.

• Fasten the cassette with the screws 1.

3.2 EMC regulations
To comply with the current EMC regulations, it is necessary to connect the

lines leading in and out of the head-end station using F terminals.

When mounting the cassette in a STR 1 9-8 head-end station which is in-

stalled in a 19” cabinet, make sure the connections leading in and out for
the 19” cabinet are made using F terminals.

The at tenuation of s hielding of t he conne ction lines for ASI and an tenna

must meet the requirements for “Class A”.

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.

Caut ion

– 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 sof tware 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

6 (s. chap. 3.3) with the top side of the CA

module facing the top side of the cassette.

• Push the CA module without canting into the guide rails of the CA slot 6 and
contact it to the common interface.

Selecting the channel strip

.

“OUTPUT” menu is activated.

Selecting channel / frequency setting

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 C5 … C12 and C21 … C69,
the frequency setting covers the range from 42.0 MHz to

860.0 MHz.

The COFDM 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 C21 … C69 (frequency raster 8 MHz). The CCIR
channel raster is 7 MHz in the range of the lower frequency
bands (channels C5 … C12). If 8 MHz COFDM 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 ranges below them, we recommend starting with
frequency 306 MHz going back in steps of 8 MHz (s. fre­quency table on page 50).
Please note thereby that many receivers cannot receive the
channel ranges S21 … S41 (306 … 466 MHz).

Setting the output signal

In this menu, you can set the bandwidth, the carrier modulation
and the spectral position of the output signal.

Bandwidth of the output signal

To transmit the output signal in the channel range of C21 to
C69 a bandwidth of 8 MHz can be used.
In the channel range of C5 to C12 a bandwidth of ≤ 7 MHz
must be set.
If frequency setting is selected you can set the bandwidth
dependent on the frequency of the neighbouring-channel.

•

Use to set the bandwidth of the output signal
(“5 MHz” … “8 MHz”).

Carrier modulation

In this menu item the carrier modulation is set. At this the
setting “QPSK” corresponds to the lowest and the setting
“QAM64” to the highest output data rate.

• Use the

▶

◀

/

buttons to place the cursor under ”

QPSK /

QAM…

”.

• Set the carrier modulation of the output signal using the
buttons (“QPSK”, “QAM16”, “QAM64”).

Inverting the user signal

For exceptional cases and “older” digital cable receivers, the
spectral position of the user signal can be inverted “NEG”

.

The default setting is

“POS”.

Setting the transmission parameters

In this menu you can set the transmission modes, the code
rate and the guard interval.

Transmission mode

In this menu item you set the quantity of carriers:
2k mode: 1512 carrier for user data (total 1705 carriers)
4k mode: 3024 carrier for user data (total 3410 carriers)
8k mode: 6048 carrier for user data (total 6817 carriers)
—> The standard modes for

DVB-T are 2k and 8k.

• Using the buttons set the transmission mode re-

quired (“2k” … “8k”).

Code rate

During a transmission data can be lost or changed. To recover
this data redundancy is added to the signal to be transmitted
(forward error correction). The factor of the quantity of redun­dancy contained in the bits transmitted is called code rate.
Using the setting “C7/8” you can get the highest output data
rate at lowest redundancy.

• Use the

Guard interval

In this menu item you set the relation of the duration of the
user symbols to the duration of the guard intervals to be
transmitted. A high guard interval, e.g.

“G1/4”

causes a low
output data rate. For cable networks the setting “G1/32” is
adequate.

•

—> The “Setting the transmitter identification” –
“COFDM TPS” menu is activated.

Setting the transmitter identification

At terrestrial transmission an identification is referred to each
COFDM modulated transmitter. When COFDM modulated
signals are fed into cable networks this identification is not
necessary usually. If receiving problems should occur you
must refer a transmitter identification (CELL ID) to each output
channel and switch ”on” the transmitter identification.

• Use the

The current measured gross output data rate.
If the station filter is set correctly, this value is lower than

the value of the “Number 1”. The value fluctuates, since the
data rates of individual stations are dynamically modified
by the broadcasters.

—> “Number 2” is not displayed in the channel strips “A”

output data rate (“Number 1”) is not exceeded.

The data rates of the transport streams built

by the cassette can be measured at the setting
“OUTROUTE A SI=>ASI” and be displayed in the re-
spective channel strip.
