Abstract:
A method of delivering digital information includes joining a multicast group, and receiving a segment from a server directed to the multicast group. Further, the method further includes determining a transmission error has occurred resulting in an incomplete segment, and sending an error notification to the server requesting retransmission of at least a portion of the incomplete segment. Additionally, the method includes receiving a retransmission of the at least a portion of the incomplete segment. The at least a portion of the incomplete segment may be received through an IP unicast connection or as a multicast retransmission.
