Abstract:
1. A digital broadcast receiver, comprising: a demodulator to demodulate a transport stream comprising known data which is previously known between the digital broadcast receiver and a digital broadcast transmitter and is used for equalization of the transport stream; a known data output unit to detect a location of the known data; and a decoder to perform decoding on the equalized transport stream, wherein the known data is different from a field sync, a segment sync and payload data, and wherein, before the transport stream is received at the digital broadcast receiver, the transport stream has been processed by adding a Reed Solomon (RS) parity thereto, initializing internal memories of a Trellis encoder when the known data is input to the Trellis encoder, 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.
