Abstract
The present invention concerns a file repair method for recovering a file, in a system for distributing content to more than one receiver, comprising, at a first receiver, the steps of receiving a set of files in a push multicast from a transmitter, receiving an identifier of a second receiver that owns a missing file that is not comprised in the received set of file; and recovering the missing file from the second receiver in a pull mode using a peer-to-peer mechanism. Another object of the invention is a method for file recovery in a server and in a peer device.
