Provided is an error correcting encoder and, more particularly, to an error correcting encoder used for an improved transmission method of the Advanced Television System Committee (ATSC), and a method thereof . The error correcting encoder for digital television broadcasting, which is suggested in the present research, includes a robust encoder for encoding a one-bit input into robust encoded data; a pre-coding block for receiving the robust encoded data and performing pre-coding to thereby produce a pre-coded signal; and a trellis encoding block for performing trellis encoding on the robust encoded data and the pre-coded signal.

L'invention concerne un codeur de correction d'erreur et notamment un procédé et un codeur de correction d'erreur utilisés pour une méthode de transmission améliorée de l'ATSC (Advanced Television System Committee). Ce codeur de correction d'erreur pour diffusion télévisuelle numérique, qui est suggéré dans la recherche qui nous intéresse, comprend un codeur robuste conçu pour coder une entrée à un bit en données codées robustes ; un bloc de précodage conçu pour recevoir les données codées robustes et assurer le précodage afin de produire ainsi un signal pré-codé ; et un bloc de codage en treillis pour assurer le codage en treillis sur les données codées robustes et le signal pré-codé.
