Patent ID: 8537918

Claim:
A digital broadcast receiver, comprising: a tuner to receive a stream; a demodulator to demodulate the received stream; and an equalizer to equalize the demodulated stream, wherein the stream is transmitted from a digital broadcast transmitter comprising a symbol-to-byte converter to convert a symbol in a first stream to a byte and an interleaver which interleaves the stream having a structure in which an initialization byte before the interleaving is arranged in a first direction, and the initialization byte as a result of the interleaving is arranged in a second direction perpendicular to the first direction, and the digital broadcast transmitter transmits the interleaved first stream to the digital broadcast receiver, wherein 2 symbols of the initialization byte are used by the digital broadcast transmitter to initialize a memory of a trellis encoder, and wherein the digital broadcast receiver further comprises: an RS decoder to perform RS decoding of the received stream, wherein the received stream comprises a parity used by the RS decoder, the parity being generated by RS encoding the initialization byte.
