Abstract
A method is provided for encoding a stream of source packets, in which a plurality of k source packets are packet-level forward error correction encoded to form a plurality of n-k error-correcting wildcard packets, wherein the k source packets and n-k wildcard packets are to be transmitted to a receiver. After the arrival of each source packet, for each byte of the source packet, the respective error correction contributions to the corresponding bytes of the plurality of wildcard packets are computed. The source packet is transmitted to the receiver without waiting for the arrival of another source packet of the plurality of source packets. For each wildcard packet byte, the error correction contribution of the source packet is summed in an accumulator. After the error correction contributions have been computed using all k source packets and summed for all n-k wildcard packets, the wildcard packets are transmitted to the receiver.
