DMD1050 Satellite Modem Board

Theory of Operation

3.12.3 Interleaving

The DMD1050 allows for interleaving depths of 4 or 8 R-S Blocks so that burst errors are spread
over 4 or 8 R-S blocks to enhance the error correction of the R-S Codec. In Closed Network
Mode, manually set the interleaver depth to 4 or 8. In DVB Network Mode, the DMD1050 sets
the interleaver depth to 12 automatically.
