System for deployment of value-added services over digital broadcast cable

A system for delivery of on-demand content at a cable multi-tuner set-top box, said system consisting of:

• a cable multi-tuner set-top box including a Digital Video Broadcasting-Cable (DVB-C) input for receiving one-way DVB-C channel, and a modem for establishing connectivity at said cable multi-tuner set-top box;
• a computing cloud configured to communicate bidirectional with said cable multi-tuner set-top box through said modem for enabling a user accessing said cable multi-tuner set-top box to request on-demand content from said computing cloud;
• and a cable headend configured to communicate with said computing cloud through an optical fiber or wireless link, and further configured to communicate with said cable multi-tuner set-top box via a unidirectional hybrid fiber-coaxial (HFC) network;
• wherein, said system is configured to initiate a tri-party communication between said cable multi-tuner set-top box, said computing cloud and said cable headend for authenticating said cable multi-tuner set-top box at said computing cloud or said cable headend, and thereafter routing said on-demand content from said computing cloud to said cable headend for delivery at said cable multi-tuner set-top box over said one-way DVB-C channel via said unidirectional hybrid fiber-coaxial (HFC) network in the form of a quadrature amplitude modulated compressed transport stream.
