The system comprises a plurality of geographically distributed edge servers, each connected to a storage unit configured for locally storing a copy of a distributed database with a plurality of encoded copies of a plurality of media content elements and an authorization server which receives a request for streaming any of the plurality of media content elements to a client terminal in a relative proximity to a first of the geographically distributed server.
