The Newtec AZ860 Concentrator-Deconcentrator is the ideal
product to realize transparent and efficient transmissions
of several MPEG Transport Streams on a single transmission
channel, such as a satellite DVB-S or DVB-S2 carrier, or a terrestrial
The concentrator is installed at the transmit side and is designed
to combine up to 8 input Transport Streams into one single
stream on an ASI interface. The deconcentrator is installed at
the receiving end and restores the original Transport Streams.
The concentration/deconcentration process is completely
transparent and the combined stream is fully compatible with
MPEG/DVB transmission equipment.
The AZ860 makes use of an innovative proprietary concentration
technology developed by Newtec. This technology combines
Transport Streams into a single MPEG stream without changing
anything in their content, their bit rate or their clock reference
information (PCR). This feature is essential in networks with strict
synchronisation requirements like SFN networks where adjacent
towers are transmitting on the same frequency.
The AZ860 is widely used in primary distiribution networks for
terrestrial and mobile TV.
The AZ860 Concentrator – Deconcentrator also contains
a proprietary scrambling feature to protect each stream
individually against piracy. The inputs of the concentrator and
the outputs of the deconcentrators are standard ASI interfaces.
The concentrator and the deconcentrator are part of the Azimuth
family and are available as stand alone units.
The deconcentrator functionality can also be integrated in a
demodulator allowing deconcentration of up to 4 ASI streams
The AZ860 is easy to operate and monitor. All control and
monitoring parameters are available locally on the front panel
and remotely through a web interface. It is also possible to
control or monitor the AZ860 via RMCP or SNMP.
