Abstract: A method and apparatus are provided for transmitting an LDPC code in a multimedia system. The method includes generating an LDPC code based on a resulting parity check matrix which is generated by performing a row splitting operation on a base parity check matrix; and transmitting the LDPC code. The row splitting operation includes splitting each row block included in the base parity check matrix into row blocks, a number of the row blocks is determined based on a splitting factor, and the splitting factor is determined based on a number of repair symbols included in a repair symbol block of the base parity check matrix, a number of rows included in the base parity check matrix, and a scaling factor for determining a size of each permutation matrix in the resulting parity check matrix and a size of each zero matrix included in the resulting parity check matrix.

Abstract: A method and apparatus for receiving control information in a digital broadcasting/communication system. The method includes receiving signaling information having a fixed number of bits in a coded block of a received frame; and decoding signaling information having a variable number of bits in at least one coded block of the received frame, using the signaling information having the fixed number of bits. The signaling information having the fixed number of bits includes information about a number of Radio Frequency (RF) channels, and the signaling information having the variable number of bits includes information representing a frequency for each of the RF channels, respectively.
