    摘要: A method and apparatus for transmitting a Forward Error Correction (FEC) packet block including a plurality of FEC packets in a multimedia system are provided. The method includes generating a plurality of first FEC packet blocks by performing a first FEC encoding on a plurality of source symbols, each of the plurality of first FEC packet blocks including at least one source packet and at least one repair packet for repair of each of the at least one source packet, generating a second FEC packet block by performing a second FEC encoding on the plurality of first FEC packet blocks, the second FEC packet block including at least one repair packet for the plurality of first FEC packet blocks, and transmitting the second FEC packet block that includes, in header information of each of the at least one source packet and the at least one repair packet.

    摘要: An encoding apparatus and method in a communication/broadcasting system are provided. When an encoding symbol is generated using at least one source symbol from among total source symbols to be encoded, encoding symbols are generated by using each of the total source symbols with a uniform probability before repeatedly using any of the total source symbols.

    摘要: A method for channel coding by a transmitter in a communication system is provided. The method includes determining a degree of coded bits of a Luby-Transform (LT) code based on a coding rate of a pre-code and the number of coded bits of the LT code, selecting at least one associated bit used for coding of the coded bits of the LT code from among information bits of the LT code, depending on the determined degree, and generating the coded bits of the LT code by applying a coding function to the selected associated bits.
