Methods and apparatus for an efficient multicast file distribution system

An apparatus for transmitting a file over a wireless broadcast network, the apparatus comprising:

• processing logic configure to:
• encode the file with a selected encoding scheme to form encoded packets;
• generate file delivery protocol (FDP) packets from the encoded packets;
• and
• generate a file delivery control protocol (FDCP) packet that comprises encoded control information associated with the FDP, wherein the FDCP packet comprises a file identifier and an encoding identifier identifying one or more forward error correction schemes for decoding the FDP packets;
• and
• transmitter logic configured to transmit the FDCP packet in a first wireless communication channel and the FDP packets in a second wireless communication channel over the wireless broadcast network.

An apparatus, comprising:
