Abstract:
1. A digital broadcasting transmitter, comprising: a first Reed-Solomon (RS) encoder for performing RS encoding of a transport stream (TS), the TS comprising a robust data packet, a known data and a normal packet; an interleaver for interleaving the RS encoded stream; a Trellis encoder for Trellis-encoding the data output from the interleaver; a second RS encoder for RS-encoding the robust packet of the Trellis-encoded data to alter parity and inputting it to the Trellis encoder; and a modulator for modulating the data output from the Trellis encoder and performing RF upconverting, wherein the Trellis encoder has a memory for Trellis encoding, and initializes a value of the memory at a beginning location of the known data in the TS.
