Patent ID: 8467458

Claim:
A digital broadcast receiver, comprising: a demodulator to receive a transport stream (TS) transmitted from a digital broadcast transmitter and demodulate the received TS, the TS comprising a known data which is a certain signal pattern which is predefined between the digital broadcast transmitter and the digital broadcast receiver and a RS parity encoded in the column direction; a known data output part to detect a location of the known data from the TS; an equalizer to equalize the demodulated TS using the known data; a transversal Reed Solomon (TRS) decoder to correct errors of the equalized TS using the RS parity encoded in the column direction, wherein the TS is generated by a digital broadcast transmitter comprising: an RS encoder to perform RS encoding the TS comprising the known data and the RS parity encoded in the column direction to add a RS parity to the TS; an interleaver to interleave the RS encoded TS; and a Trellis encoder to perform Trellis encoding the interleaved TS using internal memories, and to reset the internal memories at a beginning location of the known data.
