Member Function Documentation

void atsci_trellis_encoder::encode ( atsc_data_segment  out[NCODERS],
const atsc_mpeg_packet_rs_encoded  in[NCODERS] 
)

Take 12 RS encoded, convolutionally interleaved segments and produce 12 trellis coded data segments. We work in groups of 12 because that's the smallest number of segments that composes a single full cycle of the encoder mux.
