摘要： A DTV transmitter includes a pre-processor pre-processing supplemental data, a multiplexer multiplexing pre-processed data with main data, and a byte-symbol converter converting each data byte of the multiplexed data into a symbol. It further includes a symbol processor processing each supplemental data symbol outputted from the byte-symbol converter. It encodes one of upper and lower bits of each supplemental data symbol into first and second data bits, post-decodes the first data bit, and outputs the post-decoded data bit and the second data bit as a symbol. The DTV transmitter further includes a symbol-byte converter converting each symbol outputted from the symbol processor into a data byte.

摘要： A digital television (DTV) transmitter/receiver and a method of processing data in the DTV transmitter/receiver are disclosed. In the DTV transmitter, a pre-processor pre-processes the enhanced data by coding the enhanced data for forward error correction (FEC) and expanding the FEC-coded enhanced data. A data formatter generates enhanced data packets including the pre-processed enhanced data and inserts known data to at least one of the enhanced data packets. A first multiplexer multiplexes the enhanced data packets with main data packets including the main data. And, an RS encoder RS-codes the multiplexed main and enhanced data packets, the RS encoder adding systematic parity data to each main data packet and adding RS parity place holders to each enhanced data packet. Herein, the RS encoder may insert non-systematic RS parity data or null data into the RS parity place holders included in each enhanced data packet.

摘要： Disclosed are a channel equalizer and digital television receiver using the same. The equalizer comprises a channel estimator, a channel distortion compensator and noise canceller. The channel estimator estimates an impulse response of a transmission channel from a received signal. The channel distortion compensator transforms and processes the received signal and the estimated impulse response. The noise canceller predicts and eliminates amplified noise generated during equalization.
