Abstract: Data which is transmitted over the internet or other transmission networks is first divided up into individual information packets, transmitted and then reassembled into useful data after reception. Parity packets are included in with the information packets in the transmission of data in order to enable the regeneration of any information packets which were lost or damaged during transmission. The grouping of information packets and parity packets derived therefrom is termed a chunk. Chunk arrangements to recover from all cases of single and double lost packets are disclosed. Bursts of lost packets are recovered by interleaving the transmission of packets from different chunks. If the recovery is not successful then retransmission occurs in a manner similar to TCP.
