Abstract: Peer to peer distribution is provided by a digital media clearing house platform, where content is transferred from one peer (provider) to another (recipient) in return for a payment. When the recipient pays, a portion of the payment is passed to the owner of the rights in the content, according to an agreement enforced by the digital media clearing house platform. Thus, a peer in a peer-to-peer system who distributes content is compensated for the role played by that peer in the distribution of the content, and content owners maintain control over the licensing and distribution of content. The digital media clearing house platform may be implemented using a content metadata repository, an online transaction processing engine, and a purchasing side user interface to provide distribution of digital rights managed content.
