Abstract
A method of distributing media content over networks where content is shared includes coupling downloading metadata, which is accessed to start downloading media contents from the network, with semantic metadata representative of the semantic information associated with at least one of the content, and with source metadata indicative of the source of the media content. At least one of the semantic and the source metadata may be made accessible without downloading, even partially, the media content. A digital signature may also be applied to the metadata to enable the verification that, at reception, the metadata is intact and has not been subjected to malicious tampering.
