The STV0900 features a high speed DVB-S2 Forward Error Corrector (FEC) which is designed to handle up to 180 Mega Channel bits per second at its input. To feed the FEC the STV0900 implements two identical demodulators, each capable of handling QPSK legacy, DVBS2 constant coding and modulation for satellite broadcast and Advanced Coding and Modulation for interactive services. The STV0900 supports mode switching on a frame basis without synchronization or data loss.
