Abstract:
1. 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 which is generated by encoding the data in column direction, and known data which is previously known between the digital broadcast transmitter and the digital broadcast receiver; an equalizer to equalize the demodulated transport stream using the known data; and a decoder to perform decoding on the equalized transport stream, wherein the known data is different from payload data, 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 adding a Reed Solomon (RS) parity thereto, and regenerating an RS parity according to the initialization of the internal memories so that the added RS parity is replaced with the regenerated RS parity.
