TeamCast Green4Cast
DVB-T/T2 or ISDB-T/TB OEM Modulator
The Green4Cast product line is targeted to meet transmitter manufacturers requirements for high efficiency as well as high quality DVB-T/T2 or ISDB-T/TB transmitting products and is designed to be integrated within high, medium and low power Broadcast Transmitters.
It consists in high-end digital OEM DVB-T2 or ISDB-T/TB modulator featuring latest state-of-theart Digital Adaptive Pre-correction (DAP) circuits in a very compact and cost-effective platform.
Applications
- Transmitter manufacturing
- DVB-T/T2 or ISDB-T/TB transmission
Highlights
GAP® – Green Adaptive Processing
Green4Cast Digital Adaptive Precorrection circuits, powered by TeamCast GAP® – Green Adaptive Processing – algorithm, permits to run DVB-T/T2 or ISDB-T/TB transmitters very close to their saturation limit, with unequalled RF signal performances and allowing significant gain in term of transmitting Power Efficiency.
Low footprint
Thanks to its compact form factor, 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 software
State of the art modulation technologies
"Green4Cast inherits from the world-wide leading DVB-T2 and ISDB-T technologies designed by Enensys-TeamCast already in use in most of the commercial networks today in operation.
Enensys-TeamCast modulation cores brings unmatched standard usage flexibility.
DVB-T2 modulation core supports
MFN System A, SFN System B, SISO/MISO, Multi-PLP layered modulation and hybrid T2-Base & T2-Lite simultaneous transmission.
ISDB-T/TB modulation core supports MFN, SFN as well as multi layered modulation including «Partial Reception» mode (1-Seg modulation)."
