System and method for efficient replication of files encoded with multiple description coding
First Claim
1. A method of distributing from a first node to a plurality of recipient nodes a file encoded with multiple description coding, the method comprising:
- distributing a plurality of descriptors of a file encoded with multiple description coding (MDC) from a first node to a first group comprising a plurality of recipient nodes, wherein at least one descriptor is distributed from the first node to each recipient node of said first group but not all of said plurality of descriptors are distributed from the first node to any of the recipient nodes of said first group; and
said plurality of recipient nodes of said first group exchanging their respective descriptors such that each recipient node of said first group obtains all of said plurality of descriptors.

Abstract
A method comprises distributing a plurality of descriptors of file encoded with comprising a plurality of recipient nodes, wherein at least one descriptor is distributed from the first node to each recipient node of the at least a portion of the first group. The at least a portion of the first group communicate their respective descriptors received from the first node to other nodes of the first group. A system comprises an origin node operable to distribute all of a plurality of descriptors of a MDC file to a first group of recipient nodes, wherein the origin node does not attempt to communicate all of the plurality of descriptors to all of the recipient nodes of the first group. The recipient nodes of the first group are each operable to communicate a descriptor that it receives from the origin node to other nodes of the first group.
