Abstract: A method is provided for transmitting a Low Density Parity Check (LDPC) code by a signal transmission apparatus in a multimedia system. The method includes generating the LDPC code based on a resulting parity check matrix, which is generated by performing a scaling down operation on a base parity check matrix; and transmitting the LDPC code. The scaling down operation is performed based on 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, and the scaling factor is determined based on a number of column blocks included in the base parity check matrix and a size of each permutation matrix included in the base parity check matrix.

Abstract: A method is provided for channel encoding in a communication system using a Low-Density Parity Check (LDPC) code. The method includes grouping information bits into a plurality of groups; determining an order of the plurality of groups to be shortened, based on whether a specific region in a frame is to be LDPC-encoded, where the specific region has a different ratio of a number of bits to be shortened to a number of bits to be punctured; determining a length of an information word to be obtained by shortening the plurality of groups; shortening the plurality of groups on a group basis in the determined order based on the determined length of the information word; and LDPC-encoding a shortened information word.

Abstract: A method and apparatus of transmitting/receiving a packet in a system are provided. The method includes dividing each symbol corresponding to each row of a two-dimensional array having a predetermined symbol size (T) as a width into a predetermined number (m) of regions, sequentially arranging source packets to be transmitted, starting from a first column of a first row of the two-dimensional array, setting a remaining part of a region in which last data of a source packet is allocated in a last row in which the source packet is arranged to a predetermined value, arranging a next source packet, starting from a starting point of a region next to the region in which the last data is allocated in the last row in which the source packet is arranged, constructing a source block by arranging all of the source packets in the two-dimensional array, FEC-encoding the source block, and transmitting the FEC-encoded source block.

Abstract: A method for transmitting a packet in a communication system is provided. The method includes dividing a data stream into data payloads of a predetermined size and adding a common header to each of the data payloads, to generate a source payload, adding a first Forward Error Correction (FEC) payload Identifier (ID) to the source payload and applying an FEC code thereto, to generate an FEC source packet for a source payload, adding a second FEC payload ID to at least one parity payload and applying an FEC code thereto, to generate an FEC parity packet for the at least one parity payload, and transmitting the FEC source packet and the FEC parity packet.
