ABSTRACT:
A data delivery system facilitates transmission of data packets from a content server to multiple clients over a unidirectional network. A redundancy formatter resident at the server groups multiple data packets into a redundancy group and generates at least one redundancy packet containing redundancy information derived from the data packets in the redundancy group. The data packets and redundancy packet are sent over the unidirectional network to the client. In the event that a packet is lost, a packet rebuilder resident at each client reconstructs the missing data packet from the successfully transmitted data packets in the redundancy group and the redundancy packet for the redundancy group.
