摘要： Methods and apparatus for an efficient multicast file distribution system. A method for transmitting a file over a distribution network includes encoding the file with a selected encoding scheme to form encoded packets, generating file delivery protocol (FDP) packets from the encoded packets, generating a file delivery control protocol (FDCP) packet that comprises control information associated with the FDP packets, and transmitting the FDCP packet and the FDP packets over the distribution network. A method for receiving a file over a distribution network includes receiving a FDCP packet and FDP packets, decoding the FDP packets based on the FDCP packet to generate encoded packets, and generating at least a portion of the file from the encoded packets.

摘要： In general, this disclosure describes techniques for exchanging information between a plurality of encoder modules and a multiplex module to combine segments of data from the encoder modules with an improved overall quality. In particular, the encoder modules associate their respective segments of data with quality and rate information and send at least the quality and rate information associated with the segments of data to the multiplex module. The multiplex module analyzes the quality and rate information to determine whether the segments of data that encoder modules desire to include in the current superframe fit within the available bandwidth of a transmission channel. If the multiplex module determines the plurality of segments of data do not fit within the available bandwidth, the multiplex module selects one or more of the segments to be resized based on the quality and rate information received from the encoder modules.
