CA 2686274

A digital broadcasting receiver comprises a demodulator for receiving and demodulating a transmission stream including a normal data stream and a supplementary data stream, an equalizer for equalizing the demodulated stream and a turbo decoder for decoding the supplementary data stream from the equalized stream. The stream is processed by a digital broadcasting transmitter so that the stream is converted from a byte unit into a symbol unit, encoded and interleaved, and reconverted from a symbol unit into a byte unit and then Trellis- encoded. The turbo decoder comprises a plurality of decoders which decode the supplementary data stream, respectively, and exchange information regarding reliability of decoding with each other.
