Patent ID: 8619869

Claim:
A digital broadcast receiver, comprising: a demodulator to demodulate a transport stream received from a digital broadcast transmitter, the transport stream comprising data, a parity generated by encoding the data in a column direction, known data that is previously known between the digital broadcast transmitter and the digital broadcast receiver, and a Reed-Solomon (RS) parity of the data; a known data output unit that detects a location of the known data from the demodulated transport stream; an equalizer to equalize the demodulated transport stream using the known data; and a decoder to perform decoding on the transport stream, wherein the known data is different from payload data, the RS parity, a field sync and a segment sync, wherein the transport stream has been processed by initializing the internal memories of a Trellis encoder at a beginning location of the known data input to the Trellis encoder before the transport stream is received at the digital broadcast receiver, and wherein the transport stream has been further processed by regenerating an RS parity according to the initializing the internal memories so that the RS parity of the data is replaced with the regenerated RS parity.
