Abstract

Apparatus and methods for premises gateway functions that integrate or unify functions typically distributed across multiple devices within a content-based network. In one embodiment, the out-of-band (OOB) signaling functionality normally provided in each of a set-top-box (STB) and digital video recorder (DVR) are unified into a common OOB (e.g., DOCSIS) capable premises gateway device, thereby obviating OOB tuners and related components from each device. In another variant, the premises gateway is adapted for all-IP operation, such as for use with IP-based computers and IP set-top boxes, etc. Fully unified variants are also disclosed, wherein the DVR and/or STB functions are physically integrated within the premises gateway.

Claims

1. A premises gateway apparatus located at a first location proximate a user for use with a content distribution network, said apparatus comprising:

a first tuner configured to receive in-band signals from said network, and obtain first data from said in-band signals, said first data comprising first Internet Protocol (IP) packets;

a second tuner configured to receive out-of-band signals from said network, and obtain second data from said out-of-band signals, said second data comprising second IP packets;

a multiplexer, configured to multiplex said first data and said second data to form third signals; and

an interface configured to;

format said third signals; and

distribute said formatted signals to a plurality of consumer premises devices in data communication with said gateway apparatus.

2. The gateway apparatus of claim 1, wherein said network comprises a cable television network, and said in-band signals are delivered over said network associated with in-band Quadrature Amplitude Modulations (QAM).

3. The gateway apparatus of claim 2, wherein said out-of-band signals are delivered over said network associated with out-of-band QAMs.

4. The gateway apparatus of claim 3, wherein said interface comprises a Transmission Control Protocol (TCP) transport layer protocol and an IP network layer protocol, and said plurality of consumer premises devices comprises a personal computer.

5. The gateway apparatus of claim 3, wherein said plurality of consumer premises devices comprises an IP-enabled digital set-top box.

6. The gateway apparatus of claim 5, wherein said second tuner is further configured to transmit out-of-band signals over said network to a distant entity.

7. The gateway apparatus of claim 6, wherein said transmitted out-of-band signals comprise signals originated from said digital set-top box.

8. A premises gateway apparatus located at a first location proximate a user for use with a content delivery network, said apparatus comprising:

a tuner configured to;

receive in-band signals from said network comprising a Moving Picture Experts Group (MPEG) transport stream;

obtain first data from said in-band signals;

receive out-of-band signals from said network comprising an MPEG transport stream encapsulated in Internet Protocol (IP) packets, said out-of-band signals identified as intended for a first one of a plurality of consumer premises devices in communication with said premises gateway apparatus located at said first location proximate a user; and

obtain second data from said out-of-band signals;

a first interface configured to demultiplex and format said first data according to a protocol, and distribute said formatted first data to said plurality of consumer premises devices in data communication with said gateway apparatus; and

a second interface configured to demultiplex and at least distribute said second data to said first one of said plurality of consumer premises devices in data communication with said gateway apparatus located at said first location proximate a user.

9. The gateway apparatus of claim 8, wherein said network comprises a cable television network, and said in-band signals are delivered over said network associated with in-band Quadrature Amplitude Modulations (QAM).

10. The gateway apparatus of claim 9, wherein said out-of-band signals are delivered over said network associated with out-of-band QAMs.

11. The gateway apparatus of claim 10, wherein said at least one first premises device comprises an IP-enabled digital set-top box.

12. The gateway apparatus of claim 11, wherein said tuner apparatus is further adapted to transmit out-of-band signals over said network to a distant entity.

13. The gateway apparatus of claim 12, wherein said transmitted out-of-band signals comprise signals originated from said IP-enabled digital set-top box.

14. A method of operating a premises gateway apparatus, said method comprising:

receiving in-band signals via a first tuner from said network;

obtaining first data from said in-band signals, said first data comprising first Internet Protocol (IP) packets;

receiving out-of-band signals, via a second tuner, from said network;

obtaining second data from said out-of-band signals, said second data comprising second IP packets;

multiplexing said first data and said second data to form third signals;

formatting said third signals; and

distributing, via an interface, said formatted signals to a plurality of consumer premises devices in data communication with said gateway apparatus.

15. The gateway apparatus of claim 14, wherein said network comprises a cable television network, and said in-band signals are delivered over said network associated with in-band Quadrature Amplitude Modulations (QAM).

16. The gateway apparatus of claim 15, wherein said out-of-band signals are delivered over said network associated with out-of-band QAMs.

17. The gateway apparatus of claim 16, wherein said interface comprises a Transmission Control Protocol (TCP) transport layer protocol and an IP network layer protocol, and said plurality of consumer premises devices comprises a personal computer.

18. The gateway apparatus of claim 16, wherein said plurality of consumer premises devices comprise at least one IP-enabled digital set-top box.

19. The gateway apparatus of claim 18, wherein said second tuner is further configured to transmit out-of-band signals over said network to a distant entity.

20. The gateway apparatus of claim 18, wherein said transmitted out-of-band signals comprise signals originated from said digital set-top box.
