    Abstract: A method and an apparatus for transmitting and receiving packets in a broadcasting system are provided. The present disclosure allocates a padding size field by using padding octets, and thus can increase transmission efficiency. Also, the present disclosure does not restrict the number of padding octets while maintaining compatibility with existing disclosures, and thus can carry out as much padding as desired and as necessary. In addition, the present disclosure variably allocates the padding size field depending on the number P of padding octets, and thus can increase header efficiency. Furthermore, since the number of padded octets in a header is immediately known, the size of an actual payload is known in advance, and thus rapid transmission is possible.

    Abstract: An apparatus and method are provided for transmitting and receiving a quasi-cyclic Low Density Parity Check (LDPC) code in a multimedia communication system. In the method, a signal transmission apparatus generates a quasi-cyclic LDPC code, and transmits the quasi-cyclic LDPC code to a signal reception apparatus. The quasi-cyclic LDPC code is generated by encoding an information word vector using a child parity check matrix, generated by performing one of a scaling operation, a row separation operation, and a row merge operation on a parent parity check matrix. In the scaling operation, a size of the child parity check matrix is determined. In the row separation operation, each of rows included in the parent parity check matrix is separated. In the row merge operation, the rows included in the parent parity check matrix are merged.
