Abstract
A method for correcting at least one error in a data transmission over a packet-based communication network includes the steps of: generating a sequence of data packets for transmission over the packet-based communication network, the sequence of data packets being arranged into a plurality of packet frames, each of at least a subset of the packet frames including at least a primary data packet and a number of redundant data packets which is a function of a prescribed redundancy pattern, the subset of packet frames having a non-uniform distribution of redundant data packets therein; transmitting the sequence of data packets over the communication network; and recovering at least one missing data packet in the sequence of data packets using at least one corresponding redundant data packet in at least one subsequently received packet frame when the missing data packet is identified in a receiver of the sequence of data packets.
