Patent ID: 8787500

Claim:
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 trellis-decoded additional data without deinterleaving the normal data; an outer decoder to outer decode the deinterleaved additional data; and an interleaver to interleave the outer decoded additional data and provide the interleaved additional data to the trellis decoder, wherein the TS is constructed by processing the additional data so as to be robust against errors, and inserting the additional data in the normal data, and is further processed by trellis encoder which is reset at a predetermined time, before the TS is received at the demodulator for the demodulation.
