Abstract
A broadcast transmitting system and method are provided. The method includes performing RS encoding and CRC encoding on mobile service data bytes to build an RS frame, dividing the RS frame into a plurality of portions, adding K bytes of dummy data to one of the portions, converting data bytes of the plurality of portions into data bits, encoding each of the data bits to output data symbols, interleaving the data symbols, converting the interleaved data symbols into data bytes, forming data groups, inserting a plurality of known data sequences in each data group, deinterleaving data of the data groups, RS encoding mobile service data packets to insert first RS parity data in the data packets, interleaving data of the RS-encoded data packets, trellis encoding the interleaved data, recalculating second RS parity data based on initialization data and replacing the first RS parity data with the second RS parity data.
