Abstract: A data tracking system comprises a hub (1) for monitoring data transmissions passing through the hub. The hub (1) includes a store of audiovisual data files (2) and also has access to a number of external stores 3 of data files via respective Internet links (4). Data receivers (5), located within geographical territories (6), can access the hub (1) via respective Internet links (7) so as to request selected data files from one or more of the stores (2, 3). Each receiver (5) accesses the hub (1) in order to request a combination of data files in a desired format and for a selected platform. In response, the hub (1) collects the requested files from the appropriate stores combines them into a single file, together with an identity tag, and transmits the combined file and identity tag in an encrypted version to the receiver (5). Data transmissions are monitored in real time by a monitoring station (8), where information from the identity tag is used for accounting purposes.
