Abstract
A digital broadcast transmitting/receiving system and a method for processing data are disclosed. The method for processing data may enhance the receiving performance of the receiving system by performing additional coding and multiplexing processes on the traffic information data and transmitting the processed data. Thus, robustness is provided to the traffic information data, thereby enabling the data to respond strongly against the channel environment which is always under constant and vast change.

38. A digital broadcast receiver, comprising:
-
a tuner configured to receive broadcasting data having enhanced data, the broadcasting data being generated from reed solomon frame encoding the enhanced data, block processing the reed solomon frame encoded enhanced data, forming the block processed enhanced data into a group, packet formatting the group formed enhanced data, and post processing the packet formatted enhanced data in a digital broadcast transmitter, the group including known data in advance known to the digital broadcast receiver and the digital broadcast transmitter; a demodulator configured to perform demodulating on the enhanced data based on the known data; and a decoder configured to perform decoding on the demodulated enhanced data, wherein the demodulator comprises; an equalizer configured to channel-equalize the enhanced data based on the known data; a block decoder configured to perform soft decision decoding on the channel-equalized enhanced data; and a reed solomon frame decoder configured to perform an inverse process of a reed solomon frame encoder included in the digital broadcast transmitter. - View Dependent Claims (39, 40, 41, 42)

43. A method of processing digital broadcast data in a digital broadcast receiver, comprising:
-
receiving broadcasting data having enhanced data, the broadcasting data being generated from reed solomon frame encoding the enhanced data, block processing the reed solomon frame encoded enhanced data, forming the block processed enhanced data into a group, packet formatting the group formed enhanced data, and post processing the packet formatted enhanced data in a digital broadcast transmitter, the group including known data in advance known to the digital broadcast receiver and the digital broadcast transmitter; performing demodulating on the enhanced data based on the known data; and performing decoding on the demodulated enhanced data, wherein the step of demodulating comprises; channel-equalizing the enhanced data based on the known data; performing soft decision decoding on the channel-equalized enhanced data; and performing an inverse process of a reed solomon frame encoder included in the digital broadcast transmitter. - View Dependent Claims (44, 45, 46, 47)
