Abstract: A system includes a content management database configured to access a plurality of media signatures corresponding to a respective plurality of media assets and a signature component configured to process a media request from a requestor to access a given media asset from a content provider via a network and to generate a signature to substantially uniquely identify the given media asset, the signature being derived from media content data corresponding to the given media asset in response to accessing the media content data via the network. The signature component can also be configured to provide to the requestor the given media asset retrieved via the network if the generated media signature does not match any of a plurality of media signatures and provide the given media asset from a content storage system if the generated media signature matches a respective one of the plurality of media signatures.
