Abstract:
1. A network-based content distribution system, comprising a centralized distribution server and a number of subscriber terminals, wherein said centralized distribution server comprises a converter module for embedding content data into a digital delivery stream, said digital delivery stream containing data packets having content data embedded therein, and a transmitter module for transmitting said digital delivery stream from said centralized distribution server to at least one of said subscriber terminals via a forward network channel, and wherein said at least one subscriber terminal comprises a receiver module for receiving said digital delivery stream containing said data packets from said centralized server and an interface module for enabling access to said data packets of said digital delivery stream and/or the content data embedded therein by a subscriber, wherein said receiver module comprises a first generator module configured for automatic generation of a receipt acknowledgement upon receipt of each data packet of said digital delivery stream by said receiver module and a second generator module configured for automatic generation of an access acknowledgement upon release of each data packet of the digital delivery stream and the content data embedded therein to a user via the interface module, wherein said access acknowledgement is generated after decryption of an encrypted stream into an unencrypted data stream, said receipt and access acknowledgements to be transmitted from said at least one subscriber terminal to the centralized distribution server via a return network channel, and said centralized distribution server comprises a feedback management module for receiving said receipt and access acknowledgements transmitted from said at least one subscriber terminal to the centralized distribution server and for tracking access of the user to the data packets of said digital delivery stream and the content data embedded therein.
