Patent ID: 8542577

Claim:
A method for processing a digital television (DTV) broadcasting signal in a broadcasting receiver, the method comprising: receiving the DTV broadcasting signal from a broadcasting transmitter, wherein the DTV broadcasting signal is processed in the broadcasting transmitter by: pre-coding enhanced data for forward error correction (FEC), generating enhanced data packets, the enhanced data packets comprising the pre-coded enhanced data, known data which is known by transmitting and receiving sides in advance, and a transmission parameter that includes encoding-related information, wherein the encoding-related information is not known by the receiving side until the transmission parameter is transmitted by the transmitting side, and trellis-encoding, by a trellis encoder having at least one memory, data in the enhanced data packets, wherein the trellis encoder initializes the at least one memory at a position where the known data starts; decoding the encoding-related information from the transmission parameter; and decoding enhanced data included in the received DTV broadcasting signal based on the decoded encoding-related information.
