1. An encoding apparatus comprising:

  • a low priority buffer;

    a high priority buffer;

    a priority classifier to receive a data stream in which an importance is indicated, to indicate time information in the data stream, and to classify the data stream into the low priority buffer and the high priority buffer based on the importance and thereby store the data stream; and

    a forward error collection (FEC) encoder to perform an encoding calculation for FEC parity data generation by fetching data of the same first time zone from each of the low priority buffer and the high priority buffer to thereby configure a FEC source block, and by fetching, from the high priority buffer, data of a second time zone different from the first time zone to thereby add the fetched data to the FEC source block.
