    摘要： Data (200) is reliably transported from a sender (210) to a receiver (290) by organizing the data into data blocks, wherein each data block comprises a plurality of encoding units, transmitting the encoding units of a first data block from the sender to the receiver. The sender detects acknowledgments of receipt of encoding units by the receiver and a probability that the receiver received suffient encoding units of the first data block to recover the first data block at the receiver. The probability is tested whether a predetermined test is met. Following the step of testing and prior to the sender receiving confirmation of recovery of the first data block at the receiver, when the predetermined test is met, transmitting encoding units of a second data block. If an indication of failure to recover the first data block is received at the sender, sending further encoding units for the first data block to the receiver. The predetermined test is a comparison of the probability againstt the threshold probability and the predetermined test is met when the probability is greater than the threshold probability.

    摘要： 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.
