Abstract
A digital television (DTV) transmitter includes a first randomizer randomizing enhanced data; a Reed-Solomon (RS) frame encoder generating an RS frame; a block processor encoding data in the RS frame, outputting data symbols, interleaving the data symbols, and converting the interleaved data symbols into data bytes; a group formatting unit mapping the data bytes into data groups; a deinterleaver deinterleaving data of the data groups; a packet formatter outputting enhanced data packets; a multiplexer multiplexing the enhanced data packets with main data packets; a second randomizer randomizing the multiplexed main data packets and MPEG header data in the multiplexed enhanced data packets; a Reed-Solomon (RS) encoder RS encoding the multiplexed enhanced data packets; an interleaver interleaving data of the RS-encoded data packets; and a trellis encoding unit trellis encoding the interleaved data.
