Update interface (in the cassette)

2.3 Description

The cassettes convert up to 4 DVB-SPI data streams

in one QAM-modulated

data stream.

The cassettes are controlled via the head end station. Each cas-

sette has four

DVB-SPI

inputs and one HF output.

Each of the cassettes has

fourchannelstrips("A","B","C","D")thatareindicatedinthedisplayofthe

controlunitwith"Bx…A","Bx…B","Bx…C"and"Bx…D".

The integrated TP module (TP – Transport Stream Processing) processes the

data from the data streams. It can be used to change service information (NIT

–NetworkInformation Table),select stations/channelstripsand increase

the data rates (stuffing). The TP module enables the generation of a new data

stream from up to 4 data streams.

The processed input signals are fed via the HF output to the HF output collector

of the head end station. The output level of the cassettes can be set with the

- 6 - PEDQ 3005/4005/5005 QMX

level regulator (max. –20 dB) at the output collector of the head end station.

 When the head end station isswitched on, the two-line LC display briefly

shows the software version of the control unit and then the cassette type of the

slot occupied first.

You can use a PC or notebook to update the operating software of the cas-

settes via the 9-pin SUB-D socket (RS 232) in the cassette ("BE Flash" software).

You can find the current operating software of the cassettes on the website

"www.gss.de".

The cassettes are intended for use in the head end stations PSU12,PSU8and

PGT8

2.3.1 Software versions

Cassette

How to query the software version of the cassette is described in "Querying

software versions" on page 18.

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 41

",isdisplayed.

2.3.2 TP module functions

 WhenconvertingthetransportstreamsignalstoQAM-modulatedcablesignals,

thedatastreamcanbeaccessedviatheintegratedTP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

TP module.

Station filter

Individual stations and channel strips can be switched on or off. This changes

thedatarateand,consequently,theoutputsymbolrate.

Stuffing

The transport stream is padded using what is referred to as zero data. This

increasesthedatarateand,consequently,theoutputsymbolrate.Changing

the output symbol rate alters the bandwidth used appropriately (halving the

output symbol rate roughly halves the bandwidth at the output).

- 7 - PEDQ 3005/4005/5005 QMX

Changing service information

The transport stream contains data in the form of tables that the receivers evalu-

ate and require for convenient use. The TP module can change the "Network

Information Table" (NIT). The "NIT" contains data that is required by the set-top

box for the automatic search feature.

2.3.3 Explanation of the term "symbol rate"

Modulation methods such as QPSK and QAM transmit multiple bits simultane-

ously. These are referred to as symbols. Error correction bits are transferred in

addition to the user data stream which transmits video and audio information.

The FEC number specifies the ratio of error correction bits to user bits.

Processing small symbol rates

A low data rate means that the output symbol rate will be very low. With some

digitalreceivers,thismaycausereceptionproblems.Thiscanberemediedby

using the stuffing option to set the QAM modulation to a higher value.

Defined symbol rates

Some cable operators specify a fixed symbol rate (e.g. 6900 kilosymbols per

second).

2.4 Updating the cassette software

The RS-232 interface required to update the cassette software is fitted on the

board inside the cassette.

Observe the ESD protective measures!

 • Screw3screwsS (TORX TX6) out of the cassette cover.

 • Pushthecassettecoverbackwardsandremoveit.

 • UseanRS-232cabletoconnectthePC/laptoptotheRS-232interfaceof

the cassette and update its operating software with the "BE-Flash" software.

You can find the current operating software of the cassettes on the website

"www.gss.de".

RS 232

 • Afterprogramming,pushthecassettecoverfromthebackintotheguidesof

the cassette and fasten it with the 3 screws S.

3.1 Installing the cassette

Note

Pull the mains plug of the head end station out of the mains socket before

inserting or replacing any cassettes.

 • 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.

3.2 Connecting the cassette

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

leading in and out of the head end station (e.g. cinch, HF) using cable termi-

nals.

When mounting the cassette in a head end station which is installed in a 19"

cabinet, make sure that the connections leading in and out (e.g. cinch, HF) at

the 19" cabinet are made using cable terminals.

 • Inserttherequirednumberofstandardcableterminals(e.g.cinch,HF)inthe

open ings provided (knock-outs) in the front of the head end station or the

19" cabinet.

—> The cable terminals used are standard and are not included in the scope

of delivery.

Tighten the nuts of the cable terminals until the teeth on the lock washers put

under the nuts have penetrated the exterior coating and a good connection is

made between the housing and cable terminal.

played instead of the "Channel setting" menu.

Bx 1

112.00 MHz

OUTPUT:

The QAM signal is normally transmitted with a bandwidth of 8 MHz. That

means that you can only use the mean channel frequency of the existing chan-

nel raster in the range of channels S21 … C69 (frequency raster 8 MHz). The

channel raster is 7 MHz in the range of the lower frequency bands (channels

C2 … S20).

That is why the frequency setting is used here. If one were to use the normal

channel raster in these channel ranges, this would result in interference (over-

lapping) with the 8 MHz QAM signal packages, thus causing transmission

problems.

Adapting the output level

This setting is not essential for these cassettes.

 Underthismenuitem,the"control" setting is used to set a digital carrier to the

analogue video carrier frequency of the output channel. This makes it possible

to measure the absolute output level of these cassettes with an analogue test

receiver.

Setting hotel mode

The hotel mode is designed for special applications and should only activated

for these applications. If the hotel mode was inadvertently activated please

observe the section "Deactivating the hotel mode" below.

Hotel mode is required to generate a fixed assignment of the PIDs when in-

put data changes. That means that if the PIDs of the incoming data stream

change,theoutgoingdatastreamisgivenasingledefinedPID.Evenifthere
