Abstract:
1. A digital broadcast receiver, comprising: a demodulator to receive a transport stream (TS), and demodulate the received TS; a known data output part to detect location of known data from the TS; an equalizer to equalize the demodulated TS using the known data; and a TRS decoder to TRS-decode the TS, wherein the TS is generated by a digital broadcast transmitter adding an RS parity at an end position of data, inserting the known data into the data, RS encoding the data to add a parity, and interleaving the data which the know data is inserted, wherein the TS is trellis-encoded by a trellis encoder included in the digital broadcast transmitter, and the trellis encoder resets a plurality of internal memories, which are used to trellis-encode the TS, at a predetermined time in response to a control signal for controlling the memory reset.
