Abstract:
1. A digital broadcast receiver, comprising: a demodulator to receive a transport stream from a digital broadcast transmitter, the transport stream comprising known data that is known between the digital broadcast transmitter and the digital broadcast receiver, and a sync signal, and to demodulate the received transport stream; a known data output unit to detect 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 equalized transport stream, wherein the transport stream is transmitted from the digital broadcast transmitter comprising a Trellis encoder to reset internal memories used for Trellis-encoding at a beginning of the known data and to perform Trellis-encoding the known data by using the reset internal memories, and a parity replacing unit to receive data altered according to the reset of the internal memories and to regenerate an RS parity corresponding to the altered data so that an RS parity corresponding to the data before altered is replaced with the regenerated RS parity.
