Abstract:
1. A digital broadcasting reception apparatus, comprising: a demodulator to demodulate a transport stream (TS) comprising normal data and additional data; an equalizer to equalize the demodulated TS; a trellis decoder to trellis decode the equalized TS; a deinterleaver to deinterleave the additional data output from the trellis decoder without deinterleaving the normal data; an outer decoder to outer decode the additional data output from the deinterleaver; an interleaver to interleave the additional data decoded by the outer decoder and provide the interleaved additional data to the trellis decoder; and a Reed-Solomon (RS) decoder to RS-decode the additional data output from the outer decoder, wherein the TS is processed by a trellis encoder which is reset at a predetermined time, before the TS is received at the demodulator for the demodulation.
