Abstract:
A method and apparatus for staggercasting are described including encoding and compressing a first data sequence, packetizing the compressed encoded data sequence to form a data packet, performing forward error correction (FEC) encoding on the data packet in order to generate a second data sequence related to the first data sequence, appending FEC control information as padding to the end of payload data of the data packet, packetizing the second data sequence to form a packet, multicasting the data packet to a first multicast group, multicasting the packet formed using the second data sequence delayed by an offset time to a second multicast group.
