Title
(EN) APPARATUS FOR PROCESSING STREAMS AND METHOD THEREOF
(FR) DISPOSITIF ET PROCÉDÉ DE TRAITEMENT DE FLUX
Abstract
(EN)
An apparatus for processing streams is disclosed. The apparatus includes a trellis encoding unit which changes a part of streams with parities, a RS re-encoding unit which corrects at least one of parity part and data part of the streams, and generates new codewords to match the changed part of the streams, and a multiplexer which re-constructs the streams with the generated codewords. This enhances a reception quality of a broadcasting receiver.
(FR)
Le dispositif de traitement de flux de l'invention comprend: une unité de codage en treillis qui modifie une partie des flux avec des parités; une unité de re-codage de Reed-Solomon qui corrige au moins soit la partie parités, soit la partie données des flux, et génère des nouveaux mots codés pour adaptation à la partie changée des flux; et un multiplexeur qui reconstruit les flux avec les mots codés générés. Il en résulte une meilleure qualité de réception du récepteur de diffusion.
