Method for packet-level FEC encoding a stream of source packets using shifted interleaving
Abstract:
A method for transmitting interleaved shares of packet-level FEC encoded packets, in which a given time shift occurs between consecutive shares, includes determining a current state; associating a packet with a share based on the current state; and determining a position of the packet within the share. Each share includes source packets and error-correcting or wildcard packets. If the position of the packet corresponds to a source packet position, a contribution of the packet to the wildcard packets of the share is computed, and the packet is transmitted as a source packet. If the position of the packet corresponds to a wildcard packet position, the packet is transmitted as a wildcard packet.
