AMD-53-S2 MODULATOR / MULTIPLEXER
3. INSTALLING AND OPERATING INSTRUCTIONS
3.1. SAFETY INSTRUCTIONS
When assembling and commissioning the AMD-53-S2 MOD/MUX and executing the settings, always
follow the accompanying instructions exactly.
The devices are not to be assembled and brought into use by anybody who is not an authorised
technician.
When components are being installed in areas where reception is important, ensure that EMC
regulations are observed.
All assembly, installation and cable connection must take place when no electricity has been
connected.
The provisions of DIN EN 50083 must be observed at all times when working with the equipment. In
particular, DIN EN 60728-11 regarding safety may on no account be ignored.
3.2. GENERAL DESCRIPTION OF FUNCTIONS
The device is transport stream multiplexer and DVB-S2 modulator. With them the user‘s own digital
program “bouquets“ in the DVB-S2 carrier can be produced. The output signal are provided via RF-
output and configurable by IP interface. The signal can be broadcast or fed into the MVDS or
satellite TV network. Depending on the application, the device are pre-configured by hardware.
Using the integrated user interface, the operating parameters can be varied within wide limits.
Deliveries are made with the following configurations/ device versions:
Up to 120 input elementary transport streams are multiplexed at device and inserted into the output
DVB-S2 carrier with maximum bit rate of 100 Mbps and is transmitted via the N-type connector.
The output signal contains all the tables necessary to the program and associated services (PAT,
PMT, SDT and TDT).
3.3. MULTIPLEXER/REMULTIPLEXER/PID FILTER
A multiplexer has been integrated into the AMD-53-S2 device for processing the incoming transport
streams. On condition that in these transport streams an adequate transmission rate is available, or
additional transport volume is achievable by raising the transport streams bit rate, new services and/
or program components can be added.
PID filtering is enable in case of IP-input mode only. A raw MPEG Transport Stream consists data of
all the services transmitted on a particular transponders. The task on the remux/mux side is to filter
out the interesting packets and schedule them to their target DVB-S2 carrier.
MPEG TS packets are identified by the Packet ID, the PID. This is a 13-bit number located in the
2nd and 3rd byte of a TS packet.
