Abstract:
1. A digital broadcasting receiver, comprising: a demodulator for receiving and demodulating an encoded signal from a digital broadcasting transmitter, the encoded signal being encoded by inserting a pre-determined known data in a certain location of dual stream; an equalizer for equalizing the demodulated signal; a known data output part for detecting the location of the known data from the demodulated signal and outputting the known data to the equalizer; a decoder for error-correcting and decoding of the equalized signal using the detected known data; a deinterleaver for deinterleaving data output from the decoder; and a derandomizer for derandomizing data output from the deinterleaver, wherein an additional data stream included in the encoded signal is a stream which is first Reed-Solomon (RS) encoded, first interleaved, packet-formatted, second RS encoded, second interleaved, trellis encoded and third RS encoded by the digital broadcasting transmitter.
