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 initialization 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.
L'invention concerne un codeur en treillis comprenant un bloc qui comporte une pluralité de mémoires et génère une valeur binaire déterminée par un état des mémoires; un recodeur Reed-Solomon qui reçoit la valeur d'initialisation émise par le bloc du codeur en treillis et génère une parité correspondant à la valeur binaire; et un additionneur qui reçoit la parité générée par le recodeur Reed-Solomon et un flux de transmission comprenant une parité, et corrige la parité du flux de transmission en ajoutant la parité générée par le recodeur Reed-Solomon au flux de transmission, ce qui génère un flux de transmission à correction de parité.
