Abstract: A method and an apparatus for transmitting and receiving a packet in a broadcasting and communication system are provided. The method and apparatus allows a receiver to recognize data in a packet lost due to data loss occurring in a network. To this end, Forward Error Correction (FEC) control-related information is generated, a packet including the generated FEC control-related information is generated, and the packet is transmitted. The FEC control-related information includes at least one of FEC configuration-related information and FEC encoding configuration-related information.

Abstract: Methods and apparatus are provided for transmitting data in a broadcasting system. Input data is encoded by an encoder. A first demultiplexer generates first transmission symbols using the encoded data. The first transmission symbols are modulated, and the modulated first transmission symbols are transmitted. A second demultiplexer generates second transmission symbols using at least a portion of the encoded data. The second transmission symbols are modulated and the modulated second transmission symbols are transmitted.

Abstract: Methods and apparatuses are provided for transmitting data. A codeword is generated by encoding an information word. Parity bits of the codeword are grouped into a plurality of groups. The parity bits are interleaved according to a predetermined order. One or more of the interleaved parity bits are punctured to generate a punctured codeword. A frame including a portion of the punctured codeword is transmitted.

Abstract: Methods and apparatus are provided for transmitting and receiving encoded data. A codeword is generated by encoding an information word. Some parity bits are punctured in the generated codeword. A frame including the punctured codeword is transmitted. Additional parity bits for decoding the information word are transmitted in one or more other frames.
