摘要： A content sharing system, for implementation in a requesting peer, to receive at least a part of a chunk from a serving peer, the chunk being part of a content item, the requesting peer being operationally connected to a plurality of peers including the serving peer via a communications network, the content item being media content originally broadcast in a media stream by a Headend to at least some of the peers, the system including a metadata module to receive chunk metadata identifying the location of the chunk based on an identifier in the media stream originally broadcast by the Headend, a content transfer module to request the at least part of the chunk from the serving peer based on the chunk metadata, and receive the at least part of the chunk from the serving peer. Related apparatus and methods are also described.
