AZ860 Concentrator - Deconcentrator

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 leased line.

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 (HZ930)

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.

AZ860 Key Features

  • Concentrates and deconcentrates up to 8 DVB or ATSC Transport Streams into a single Transport Stream
  • Fully transparent: no PID translation, no PCR restamping, no rate adaptation and no modification of SI/PSI tables
  • Compliant to SFN requirements
  • Each transport stream can be scrambled and descrambled Independently
  • Matrix routing capability between the multiple inputs of the concentrator and the multiple outputs of the deconcentrator

Main Advantages

  • Reduced capital investment on hub and remote sites
  • Lower operational cost thanks to efficient use of transmission bandwidth
  • Cost effective and easy-to implement technology compared to traditional multiplexer solutions
  • Protection of the data content against unauthorized access by other parties

Applications

  • Primary distribution for Digital Terrestrial TV
  • Primary distribution for Mobile TV
  • ASI networking and routing
