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.
