DVB-S(2) / DVB-T(2) / DVB-C into DVB-C
Conversion of 4 terrestrial channels

The triple tuner reception headend PCU 4111 converts the signals of four terrestrial or cable network channels into DVB-C channels.
The four inputs are each provided with a CI interface for decoding encrypted signals. The dual modulators can split the selected channels to two output channels in order to avoid bandwidth problems. The headend can be programmed fastly and easily via the USB interface.
Features like LCN, NIT, TSP and LAN administration complete the practical functionality.
The high quality components and the “Made in Germany” in-house development and production enable you to build up reliable and durable reception systems with POLYTRON's PCU 4111.
