Title: Trellis encoding device for encoding transmission stream and method thereof

Abstract: A trellis encoding device includes a trellis encoder block that includes a plurality of memories, and outputs a bit value determined by a state of the memories; a Reed-Solomon re-encoder that receives the bit value output from the trellis encoder block, and generates a parity corresponding to the bit value; and an adder that receives the parity generated by the Reed-Solomon re-encoder and a transmission stream including a parity, and corrects the parity of the transmission stream by adding the parity generated by the Reed-Solomon re-encoder to the transmission stream, thereby generating a parity-corrected transmission stream.
