2.3Description

The Cassettes convert two QPSK-modulateddata flows into oneQAM-modu-lated data flow. The Cassettes are controlled via the head end. Each Cassette has two inputs and one HF output, as well as an integratedmulti-transportflow processor for stuffing, PID pass, drop and service filtering.

For these Cassettes, information from a barker channel can be added or exchanged with a transport flow (MTP function, Dropand service filter). For this purpose, there are two autonomous reception tuners and one modulator on which the modified transport flow can be transmitted as a QAM-modulatedsignal.

The SDT and PAT tables are automatically generated. All data relevant to the operation of the Cassette is registered in a logbook with a maximum of 500 entries.

The operating software of the Cassette can be actualised via an external 9-pinSUB-D-socket,using a PC or notebook, (software“BE-Flash”)or settings in the channel strips “A” (service channel) and “B” (barker channel) of the Cassette (PC software “MTP”, component of software PSW 1000). You can find the current operating software of the Cassettes on the website “http://www.gss.tv”.

The prepared input signals are transmitted to the HF output collector of the head end via the HF output socket. The output level of the Cassettes can be set with the level regulator (max. –20dB) at the output collector of the head end.

After the head end has been switched on, the software version of the control unit is displayed briefly in the two-lineLC display and afterwards the type of Cassette of the first slot.

Approximately five minutes after the last button has been pressed, the software version of the control unit is displayed.

The Cassettes are designed for use in the following head ends:

2.3.1 Manual display of the software version

If necessary, you can call up the display of the software version of the control unit manually:

Hold down any two keys of the control unit simultaneously until the display goes dark and the software version, e.g. “V.34”, is displayed.

2.3.2How the TP module works

When converting the QPSK-modulatedsignal to aQAM-modulatedcable signal, the demodulated data stream can be accessed via the integrated TP module. This data stream, also called transport stream, contains several stations with all their components (video, audio, data and service information), which can be changed using the TP module.

The individual functions Station filter

Individual stations can be deleted. This reduces the data rate and, consequently, the output symbol rate.

Stuffing

The transport stream is padded out using what is known as zero data. This increases the data rate and, consequently, the output symbol rate. Changing the output symbol rate suitably alters the bandwidth used (halving the output symbol rate roughly halves the bandwidth at the output).

Changing service information

The transport stream contains data in the form of tables which the receivers evaluate and require for convenient use. The TP module can change the “Network Information Table” (NIT). The NIT contains data which the set-topbox needs for the automatic search function.

2.3.3 Explanation of the term “symbol rate”

High-qualitymodulation methods like QPSK and QAM can encrypt several bits as a single transferred and received symbol. The user data stream contains the audio and video signals of a station and is thus permanently assigned. If the value of the modulation and therefore the number of bits per symbol is increased, the symbol rate falls compared to the user bit rate.

Formulae for calculating the output symbol rate “SR (A)” at a fixed input symbol rate “SR (E)” and “FEC”.

256-QAM:SR (A) = FEC x1/4 x SR (E)128-QAM:SR (A) = FEC x2/7 x SR (E)

64-QAM:SR (A) = FEC x1/3 x SR (E)32-QAM:SR (A) = FEC x2/5 x SR (E)16-QAM:SR (A) = FEC x1/2 x SR (E)

4-QAM:SR (A) = FEC x1/1 x SR (E)

Example:

Output symbol rate 64-QAM,FEC=3/4,

Input symbol rate SR (E) = 27,500 kilosymbols per second

SR (A) = 3/4 x1/3 x 27,500 kilosymbols/s

SR (A) = 6,875 kilosymbols/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 QAM modulation with stuffing to a higher value.

Defined symbol rates

Some cable operators specify a fixed symbol rate (e.g. 6,900 kilosymbols per second).

3.1 Installing the Cassette

Warning

Before inserting or changing Cassettes, pull the mains plug of the head end out of the mains socket.

Unscrew the fastening screws from the bracket in the head end.

Insert the Cassette into a free slot and push it into the housing.

Align the Cassette and gently make it contact with the connections of the circuit board and the HF bus bar.

Fasten the Cassette with the 1 screws.

Note:

The operating software of the Cassette can be updated via the socket “RS 232” 3 (9-Pin-Sub-D)by means of a PC or notebook.

Use the “BE-Flash”software as the update software. You can make drop and pass filter settings in the channel strip “B” using the “MTP” PC software. You can find the current operating software of the Cassettes on the website “http://www.gss.tv”.

5 Programming

The following examples show how the PHDQ 4002 BC Cassette is programmed; the output channels can be set from S21 … S41. Set the other Cassettes listed in the same way.

5.1Preparation

Notes:

Using the menu “LEVEL CONTROL” the Cassette generates an equally powerful HF carrier on the video carrier frequency of the channel. In this way, the Cassette‘s level can also be set with an analogue TV test receiver set to the video carrier frequency of the channel. In order to prevent interference within the head end and the cable system, the output level of the digital Cassettes must be lowered by approx. 10 dB at 64 QAM and by approx. 4 dB at 256 QAM compared to analogue Cassettes.

• Connect the test receiver to the “TEST OUTPUT” 1 of the

 

L100

head end.

• Check the output level of the digital DVB-MTPCassettes

After programming the Cassette check the output level of the Cassette again and if necessary set it again.

The QAM signal is 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 frequency raster is 7 MHz in the range of the lower channel ranges (≤ channel S20). If one uses the existing channel raster here, this will result in interference (overlapping) of the 8 MHz QAM signal packages and thus transmission problems. For programming in this channel range, we recommend to calculate the output frequency of the QAM modulator,

starting with the upper output frequency of the Cassette listed in the “Specifications” going back in steps of 8 MHz, or

starting with the lower output frequency of the Cassette listed in the “Specifications” moving up in steps of 8 MHz.
