The DVB-S DSNG FEC Encoder adds forward error correction information to a data stream according to the DVB and DVB DSNG standards. The design is compliant to the relevant sections of EN 300 421 and EN 301 210.

The Encoder accepts byte wide data and generates byte wide data complete with error correction information, ready to be fed into an external modulator function. The core performs the following operations:

• Transport Multiplex Adaptation and Randomisation (to EN 300 421)
• 204/188 (shortened) Reed Solomon Outer Encoder (to EN 300 421)
• Depth 12 Convolutional Interleaver (to EN 300 421)
• Convolutional Inner Encoder (K=7)
• QPSK Code Rates of 1/2, 2/3, 3/4, 5/6 & 7/8 (to EN 300 421)
• 8PSK Code Rates of 2/3, 5/6 & 8/9 (to EN 301 210)
• 16QAM Code Rates of 3/4 & 7/8 (to EN 301 210)
• "Parallel to Parallel" & "Parallel to Serial" Encoders (to EN 301 210)
• Symbol Sequencer (to EN 301 210)
