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.

5. The method of claim 1, wherein the determining the at least one access privilege of at least the second IP-enabled end user device comprises determining that:

(i) the second IP-enabled end user device has one or more sufficient access privileges to access the one or more digital content elements; and

(ii) the first IP-enabled end user device is within a trusted or authorized content domain which includes the second IP-enabled end user device.

6. The method of claim 1, wherein the digital content delivery network comprises a managed network having a network operator, and one or more users of the second IP-enabled end user device comprise one or more subscribers who are bound to the network operator pursuant to one or more respective subscription agreements.

7. The method of claim 1, wherein enabling automatic forwarding of the one or more digital content elements to the third end user device comprises enabling automatic delivery to a non-IP-enabled end user device.

8. The method of claim 1, wherein the first IP-enabled end user device comprises an out-of-band (OOB) data communication proxy for communication between the digital content delivery network and one or more of the second IP-enabled end user device and the third end user device.

9. The method of claim 1, wherein the enabling automatic forward of the one or more digital content elements to the third end user device at least in part comprises:

causing processing of a digital signal, the digital signal (i) received at the first IP-enabled end user device using at least the IP-based packetization protocol, and (ii) comprising at least the requested one or more digital content elements; and

causing delivery of the processed digital signal to the third end user device, the third end user device being unable to receive the one or more digital content elements without the processing of the digital signal.

10. A method of delivering digital content via a digital content delivery network, the method comprising:

transmitting, from a first Internet Protocol (IP)-enabled end user device to a computerized network entity, data indicative of a request for digital content on behalf of a second IP-enabled end user device in data communication with the first IP-enabled end user device, at least the first IP-enabled end user device disposed at a user premises;

based at least in part on the data indicative of the request transmitted from the first IP-enabled end user device, enabling determination of at least one access privilege of at least the second IP-enabled end user device, the at least one access privilege configured for accessing the requested digital content;

based at least in part on the determined at least one access privilege of at least the second IP-enabled end user device, receiving the requested digital content at the first IP-enabled end user device using at least a network layer packetization protocol, the requested digital content obtained from one or more personal content storage devices of the digital content delivery network;

based at least in part on the receiving of the requested digital content at the first IP-enabled end user device, both (i) automatically delivering the requested digital content from the first IP-enabled end user device to the second IP-enabled end user device, and (ii) automatically forwarding a processed version of the requested digital content to a third end user device; and

wherein the second IP-enabled end user device and the third end user device are disposed at the user premises.

11. The method of claim 10, wherein automatically forwarding the processed version of the requested digital content to the third end user device at least in part comprises:

enabling processing of a digital signal, the digital signal (i) received at the first IP-enabled end user device using at least the network layer packetization protocol, and (ii) comprising at least the requested digital content; and

enabling delivery of the processed digital signal to the third end user device, the third end user device being unable to receive the requested digital content without the processing of the digital signal.
