2.4 d esCription
The Head-End Digital Modulator HDTV "HDMH 660 CI TPS", in the following called DVB-S2-QAM module converts two DVB-S-/DVB-S2-modulated data streams into two QAM-modulated data streams. The DVB-S2-QAM module has two SAT-IF inputs and one HF output. Components (e.g. LNB) which are connected upstream can be powered through the SAT-IF inputs.
The DVB-S2-QAM module is equipped with two channel strips ("A" and "B").
The channel strips consist of the digital SAT tuners, the digital signal processing levels and an output converter. The channel strips for the DVB-S2-QAM module are indicated in the head-end station display with "Bx …A" and "Bx …B".
Using an adequate CA module scrambled channels can be descrambled via channel strip "A". The control of the module takes place via the control unit of the head-end station.
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 TP 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). In addition, the operator ID (required for e.g. visAvision) can be set.
The HF output signals are sent through the HF output of the DVB-S2-QAM module to the output collector.
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 DVB-S2-QAM module operating software can be updated using a PC or notebook and the software "BE-Flash" via the 9-pin SUB-D socket on the headend station. You can find the current operating software for the DVB-S2-QAM module, the software "BE-Flash" and the current assembly instructions on the website "www.gss.de".
- 6 - HDMH 660 CI TPS
The DVB-S2-QAM module is designed exclusively for use in the STC 160 headend station.
h ow 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.
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.
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.

e xpl anation of the ter m
" symbol r ate
"
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:
256-QAM: SR (A) = FEC x
1
/
4
128-QAM: SR (A) = FEC x
2
/
7
x SR (E)
64-QAM: SR (A) = FEC x

32-QAM: SR (A) = FEC x

/

SR (A)
=

x 27,500 kSymb/s
SR (A)
= 6,875 kSymb/s
—> 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).

b andwidth
effiCient assignment of 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 grid).
—> The required bandwidth (in kHz) is roughly equal to the symbol rate
(kSymb/s) plus 20%.

Caution:
The modulator in this module employs automatic neighbouring-channel assignment. This means that when the output channel or the output frequency for channel strip "A" is set, channel strip "B" will always be 8 MHz above channel strip "A".
If SelecPlex
®
will be used, the normal channel separation of 8 MHz can be reduced to 2 MHz via the frequency setting for channel strip "B".

3 i nstallation
– 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 r etrofit ting a
Ca module
The DVB-S2-QAM module is equipped with a common interface. It allows you to connect a CA module 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 module to be used to ensure that it is suitable for the reception of several channels.
– The hardware and software of the DVB-S2-QAM module have been thoroughly prepared and tested.
–
Any changes made by program providers to the structures in the program
data might impair or even prevent this function.
– When working with the CA module, please read the corresponding operating manual from the respective provider.
• Insert the smart card
• Push the CA module mon interface common interface.

In this menu, you can choose whether you require the channel or frequency setting for the adjustment of the HF output. The channel setting covers the range of channels S21 … S41 and C21 … C69, the frequency setting covers the range from 42.0 MHz to 860.0 MHz.

Channel
OUTPUT
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 grid in the range of channels S21 … C69 (frequency grid 8 MHz).
The CCIR channel grid 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 grid of 7 MHz in these channel ranges, this will result in interference (overlapping) with the 8 MHz QAM signal packages, thus causing transmission problems.
- 20 - HDMH 660 CI TPS
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 the bandwidth of the QAM output signal by removing stations.
The modulator in this module employs automatic neighbouring-channel assignment. This means that when the output channel or the output frequency for channel strip "A" is set, channel strip "B" will always be 8 MHz above channel strip "A".
If SelecPlex
®
will be used, the normal channel separation of 8 MHz can be reduced to 2 MHz via the frequency setting for channel strip "B".
Using "SelecPlex
®
" only the frequency setting can be used.
