A method and system for transmitting data are described including packetizing the data, performing forward error correction (FEC) encoding on the packetized data in order to generate at least one parity packet, appending FEC information as padding to the end of payload data of the packetized data and transmitting the packetized data and the at least one parity packet. Also described are a method and system for recovering from loss of a packet including receiving a data packet, receiving at least one parity packet, buffering the received data packet, detecting packet loss, forward error correction decoding the at least one parity packet to recover from packet loss using forward error correction information extracted from the data packet and from the at least one parity packet and forwarding the recovered packet via an internal socket. Also described is a method for staggercasting.
