Compact Headends

Multiplexing Compact Headends with 8 Triple Tuners and 4 CI ports

The multiplexing headends PXU 848 C and PXU 848 T convert the content of eight SAT, terrestrial or cable network channels into DVB-C (QAM) or DVB-T (COFDM). The multiplexing function allows to create new output channels with content from different input channels..

The new freedom of reception: Conversion of DVB-S(2), DVB-T(2) and DVB-C in DVB-C or DVB-T

The new compact headend series PCU 4000, PCU 8100 with triple tuners and PCU 8000 with DVB-S/S2 tuners offer all freedoms in the project planning of community reception systems due to triple tuners:

• compact design
• triple tuners: freely selectable input signals DVB-S(2), DVB-T(2), DVB-C
• mixed reception possible
• also with 4 CI slots for central decryption
• output options: DVB-C (QAM), DVB-T (COFDM) – switchable via firmware update
• made in Germany

Type of reception flexibly adjustable

The innovative triple tuners of the PCU 4000 and PCU 8100 headend series allow to determine the type of reception of each single tuner independently and flexibly.
DVB-S(2), DVB-T(2), DVB-C or all three – you can decide depending on the given conditions what the headend has to convert. Very easy with only one mouse click in the programming software.

Flexible content configuration

With a PCU headend you have the possibility to process the data stream. You can remove, for example, unwanted programmes of a transponder, create a LCN allocation and program the headend to a provider-specific receiver (NIT). You also have the option to split the contents of a transponder to two output channels in order to avoid e.g. bandwidth restrictions.
The PCU 4000 and PCU 8100 series headends are available with four built-in common interface slots, enabling a central decryption for the community system.

Flexible output selection

The PCU headends’ output signals can be changed easily from DVB-C to DVB-T and vice versa by a firmware update. The PCU headends are completely flexible and universal applicable.

Flexible setting of the parameters

The easy PC programming and the integrated LAN controller allow flexible and reliable management of the headend.

Universal application

Whether modernization of existing reception systems using the existing wiring or new installations, with the POLYTRON PCU series you are able to build TV reception systems on the latest state of the art.

Uncompromising: Made in Germany
