Distribution Solution
DIGICOMPACT CENTRAL STATION CHARACTERISTICS
- Transmodulation station for Satellite & Terrestrial Digital TV to Digital Terrestrial TV with C.I.
- Ideal for satellite & terrestrial digital TV distribution in hotels and communities using the TV’s with built in DTT receiver as well as the RF cabling
which is already installed.
- Possibility to combine up to 6 transmodulation boards per cabinet.
- DVB-T/COFDM output from DVB/S, DVB/S2 and DVB/T input signal.
- Optional wideband amplifier.
- Robust, lockable and ventilated aluminum cabinet with power supply and remote control.
- Compatible with previous existing systems & possibility to cascade several cabinets in a single installation.
- Easy to install (two screws per module) and to maintain (independent modules)
