Abstract:
1. A digital broadcast receiver, comprising: a demodulator configured to receive a transport stream (TS) and demodulate the received TS; a known data output part configured to detect a location of a supplemental reference signal (SRS) from the TS; an equalizer configured to equalize the demodulated TS using the SRS; and a decoder configured to decode the TS, wherein the TS is processed by adding a Reed Solomon (RS) parity at an end position of data, inserting the SRS into the data, and RS encoding, interleaving and trellis encoding the data in which the SRS is inserted, before the TS is received by the demodulator, and wherein the TS is further processed by resetting a plurality of internal memories of a trellis encoder for the trellis encoding at a start of the SRS in response to a control signal for controlling the resetting, before the TS is received by the demodulator.
