Abstract: Methods and apparatuses are provided for transmitting signaling information by a transmitting apparatus in a broadcasting system. A controller generates a codeword by encoding information bits of the signaling information. The codeword includes the information bits and parity bits. The controller punctures one or more of the parity bits to generate a punctured codeword. The controller generates a plurality of frames. The plurality of frames include a first frame including at least a part of the punctured codeword and a second frame including at least one additional parity bit for the signaling information. A transmitter transmits the plurality of frames. The at least a part of the punctured codeword is included in a preamble part of the first frame and the at least one additional parity bit is included in a preamble part of the second frame.
