FORWARD ERROR CORRECTION ENCODING/DECODING METHOD AND APPARATUS, DIGITAL BROADCASTING RECEPTION APPARATUS AND DECODING METHOD THEREOF

摘要

PURPOSE: A forward error correction encoding/decoding method, digital broadcasting reception apparatus and decoding method thereof are provided to offer low-rank compatibility by applying encoding/decoding to payload after dividing header of packet stream. CONSTITUTION: A header separating unit(210) divides a first header part from a packet stream. A block interleaver(221) performs a block interleaving of a first payload. In order that a parity packet according to the preset encoding rate is included, a systematic encoder(223) encodes the block-interleaved first payload part. A block deinterleaver(225) generates a second payload part by block deinterleaving of the encoded first payload part. A header coupling unit(240) unites the first header part, and the second header part and the second payload portion.
