Recovery from burst packet loss in internet protocol based wireless networks using staggercasting and cross-packet forward error correction
First Claim
1. A method for transmitting data, said method comprising:
- packetizing said data;
performing forward error correction (FEC) encoding on said packetized data in order to generate a parity packet;
appending FEC control information as padding to the end of payload data of said packetized data, said FEC control information including a padding length, a source block number and an encoding unit ID, the padding length indicating an amount of octets forming the FEC control information;
transmitting said packetized data including the FEC control information, enabling backward compatibility with non-FEC systems, and said parity packet.

Abstract
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 a 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 a parity packet, buffering the received data packet, detecting packet loss, forward error correction decoding the parity packet to recover from packet loss using forward error correction information extracted from the data packet and from the parity packet and forwarding the recovered packet via an internal socket. Also described is a method for staggercasting.
