Abstract
System, apparatus and method are provided for transmitting and receiving packets over first and second channels. An FEC encoder generates forward error correction (FEC) packets corresponding to an original stream of packets. A packet transmitter transmits the original stream of packets over the first channel and transmits the FEC packets over the second channel. A packet receiver receives a stream of packets over the first channel, and receives the FEC packets corresponding to the stream of packets over the second channel. An FEC decoder uses information stored in the FEC packets to determine a correspondence between the FEC packets and the stream of packets, and recovers one or more lost packets of the stream of packets using the FEC packets.
