2.4 d e s C r i p t i o n The Head-end Digital Transmodulator QAM "HDMA 784 C ASI", in the fol- lowing called QAM module converts two DVB-S/DVB-S2 (also 16/32 APSK) modulated data streams into four DVB-C (QAM) modulated data streams. The QAM module has two SAT-IF inputs, one ASI input and one HF output.
