System overview.
The VP305/6 decoder, together with the SL1710 I/Q down converter and the VP216/7 dual analog to digital converter (ADC) devices will provide a DVB compliant, satellite receiver system, see figure 2 on page 9. Before transmission, the data is processed using forward error correction techniques. Energy dispersal is added to even out ones and zeros for the power handling of the satellite output transmission devices. The VP305/6 device decodes the signal by reversing all these encoding techniques.
