System for deployment of value-added services over digital broadcast cable
A cable set-top box and cable distribution system architecture for deployment of value-added services over digital video broadcasting-cable is disclosed. A consumer can request for an on-demand service or a data at the cable set-top box system 122 , where the request may be executed by extracting data from storage means provided in the cable set-top box, and/or the request may be forwarded via a wireless data modem to a telecommunication network where the source of the request is identified and routed to a corresponding cable headend 106 for execution through the DVB-C and/or the modem, and/or the request may be forwarded by the modem via the telecommunication network to a computing cloud 130 where the source of the request is identified and routed to the corresponding cable headend 106 for execution through the DVB-C and/or the modem.
1. 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.
2. The system as claimed in claim 1 , wherein said cable multi-tuner set-top box contains a high-definition multimedia interface, a Wi-Fi hotspot, an RF interface, an infrared interface and IP telephony interface.
3. The system as claimed in claim 1 , wherein said cable multi-tuner set-top box contains a CVBS and a S/PDIF output.
4. The system as claimed in claim 1 , wherein said cable multi-tuner set-top box contains a hard disk interface operatively connected to at least one tuner of said cable multi-tuner set-top box.
5. The system as claimed in claim 1 , wherein said cable multi-tuner set-top box contains an optical fiber interface for enabling fiber-to-home connectivity on said cable multi-tuner set-top box.
6. The system as claimed in claim 1 , wherein said system is configured to employ the available spectrum of HFC network for delivering said on-demand content from said cable headend to said cable multi-tuner set-top box.
7. The system as claimed in claim 1 , wherein said system is configured to employ a digital storage media command & control (DSM-CC) program for delivery of said on-demand content at said cable multi-tuner set-top box.
8. The system as claimed in claim 1 , wherein said cable multi-tuner set-top box contains a high-speed downlink packet access (HSPDA) modem for establishing the connectivity with said computing cloud.
9. A method for delivery of on-demand content at a cable multi-tuner set-top box, said method consisting of:
requesting on-demand content at said cable multi-tuner set-top box from a computing cloud by establishing a bidirectional connectivity between said cable multi-tuner set-top box and said computing cloud via a modem;
communicating said on-demand content from said computing cloud to a cable headend where said computing cloud and said cable headend are connected by means of an optical fiber or wireless link;
forwarding said on-demand content from said cable headend to said cable multi-tuner set-top box via a unidirectional hybrid fiber-coaxial network, where by initiating a tri-party communication between said cable multi-tuner set-top box, said computing cloud and said cable headend, said cable multi-tuner set-top box is authenticated at said computing cloud or said cable headend, and upon successful authentication said on-demand content is delivered at said cable set-top box over one-way DVB-C channel via said unidirectional hybrid fiber-coaxial (HFC) network in the form of a quadrature amplitude modulated compressed transport stream.
10. The method as claimed in claim 9 , wherein said on-demand content includes broadcast tv, canned content, global channels, local content, T-commerce, applications and educational courses.
11. The method as claimed in claim 8 , said method including pushing said on-demand content over said one-way DVB- C channel using digital storage media command and control (DSM-CC) program.
