The core of MEX II is represented by a new modulator card that implements all the modulation, control and supervision functions.
All operations necessary for the generation of a high quality RF signal, in accordance with all analog television standards (ATV) B/G/D/K/M/N (including NICAM) and digital television standards (DTV) DVB-T/H, ATSC, DVB-T2, ISDB-Tb, are completely performed by a Real Time Digital Signal Processing using a FPGA.
By loading two different firmware in the memory card, the modulator can operate as Dual Cast, with the possibility to switch from analog to digital transmission with a simple command (local or remote).
