Abstract:
1. A digital broadcast receiver, comprising: a demodulator to demodulate a transport stream received from a digital broadcast transmitter, the transport stream comprising payload data, a field sync, a segment sync 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 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 according to a control signal, 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 initializing the internal memories so that the added RS parity is replaced with the regenerated RS parity.
