Green4Cast
DVB-T/T2 & ISDB-T/TB OEM Modulator
Green4Cast is an OEM Modulator, fully compliant to DVB-T/T2 Standards as well as ISDB-T/TB standards, targeting transmitter manufacturer requirements to design high quality terrestrial transmitters. Compact and cost effective, with its latest generation of Digital Adaptive Precorrection, Green4Cast is the ideal solution to build your high, medium and low power Digital TV Transmitters.
Highlights
DVB-T/T2 & ISDB-T/TB Standards
With its multi-standards modulation core, your TV transmitters based on Green4Cast are ready for the main world wide market: no need to redesign, that's just a question of set up.
GAP® – Green Adaptive Processing
Green4Cast Digital Adaptive Precorrection permits to run DVB-T/T2 or ISDB-T/TB TV transmitters very close to their saturation limit, with unequalled RF signal performances and allows significant gain in term of transmitting Power Efficiency.
Very compact module
With its small size, Green4Cast can be easily integrated into a transmitter. It comes with a complete software API that allows the user to integrate the control and monitoring of the module into its own control unit
MFN & SFN Transmissions
In DVB-T/T2 Mode and ISDB-T/TB Mode, Green4Cast is performing MFN & SFN Transmissions: the synchronisation can be based on 1PPS/10MHz external signal as well as on its internal GPS/Glonass Module.
