Transmodulator Hexa DVBS/S2 - DVBC (QAM Annex A) Televes
Transmodulator that generates six QAM multiplexes (DVB-C) from services available on six SAT TV transponders. The inputs can be bridged or independent. In this last case, each TVSAT demodulator can be connected to any of the two inputs. Televes 564501

Transmodulator that generates six QAM multiplexes (DVB-C) from services available on six SAT TV transponders. The inputs can be bridged or independent. In this last case, each TVSAT demodulator can be connected to any of the two inputs.
Stands out for
- Provides overlap information, constellation accommodation and input SNR
- Very optimized consumption: allows to make very compact and reduced headers with a large number of services
- Remotely controllable with the CDC (Head Control)
Features
- Insertion of null packages ("Stuffing"), allows faster scanning by the receiver (STB)
- Direct digital conversion
