Abstract
Forward error correction may be implemented in a network having first, second and third nodes. The second node receives streaming media message packets and one or more check packets from an upstream first node. The second node transmits the message packets and check packets to a downstream third node. The second node uses the check packets to decode missing message packets and transmits the decoded missing packets to the third node before the missing message packets are to be presented by the third node. The third node may receive message packets and a first set of check packets from the second node and a second set of check packets from the first node. The third node may use check packets from both sets to decode missing message packets.
