Conversion of 8 DVB-S/S2 transponders into DVB-C or DVB-T

The new PCU 8000 series HDTV compact headends convert signals from 8 satellite transponders into either DVB-C or DVB-T channels. 
The transport stream can be modified e.g. to delete programs, to adapt NIT / ONID data or to sort channels (programmes) using the LCN function. The PCU 8000 headends feature also allocating new TS IDs or SIDs with the remapping function.

for 2 applications

In many buildings the existing distribution structures with coax cables make the installation of multiswitches too expensive because new cables would have to be installed. POLYTRON's new SCA 32 is to be used in this case.

  • for single cable distribution systems
  • ideal for apartment buildings and multi-family houses
  • power supply, power-inserter and termination resistors included in delivery

1x HDMI in DVB-S

Modulator for conversion of a HDMI signal into a DVB-S signal.
The HDM-1 SL can be used flexibly and is able to process HDMI signals e.g. from satellite receivers, personal computers, cameras or DVD players.
HD signals are fully preserved.

The output channels can be fed into multiswitch distribution systems and / or can be received by common DVB-S receivers or TV sets with built-in digital tuner.

4x HDMI in 2x DVB-C / DVB-T modulator

The modulator module SPM-H4TCT converts four HDMI signals into two DVB-C or DVB-T channels.

With the four HDMI inputs, four signals of digital receivers, DVD players or other HDMI sources can be processed and fed into the network with a single module. The changeable type of modulation allows the distribution of the output signals via cable (DVB-C / QAM) or terrestrial networks (DVB-T / COFDM).
In a single base unit SPM 2.000 up to six modules (up to 24 HDMI inputs), in a single base unit SPM 200 two modules (8 HDMI inputs) can be run.

Twin DVB-S/S2 to DVB-C/T module with 2x CI

The SPM-STCT-CI is a twin module with two DVB-S/S2 inputs, two CI interfaces and changeable output modulation via menu.
Both independent tuners have got one CI interface which allows reception and central decryption of two DVB-S/S2 transponders which are processed to DVB-C or DVB-T afterwards.
The output signals can be processed for distribution in DVB-C (QAM) or DVB-T (COFDM) networks due to the changeable output modulation.
