Abstract

Methods and apparatus for selecting digital access technology for programming and data delivery over, e.g., a content-based network. In one embodiment, the network comprises an HFC cable or satellite network that includes a server process interfacing with a plurality of customer premises equipment (CPE), and/or associated client devices, each having different capabilities profiles. The server determines the one or more capabilities possessed by the CPE, and evaluates one or more program or content choices for possible delivery to that CPE based on its profile. The server generates a list of programs or content based on this evaluation, and transmits this list to the CPE, which displays the list for viewing by a user. The user is therefore offered a list of available content that is compatible with their specific configuration. A business and operational rules engine is also optionally employed to control the operation of the foregoing processes to accomplish particular business or operational goals.

obtaining first information relating to capabilities of a plurality of particular client devices serviced by said node;

obtaining second information relating to program requests from said plurality of particular client devices; and

comparing said first information relating to said capabilities of said plurality of particular client devices to said second information relating to said program requests to identify at least one of said plurality of programs as being both;

(i) requested by each of said plurality of particular client devices, and (ii) in a format which is determined that each of said plurality of particular client devices are capable of accessing.

2. The method of claim 1, wherein said first information comprises information relating to conditional access (CA) capabilities available to individual ones of said plurality of particular client devices.

3. The method of claim 2, wherein said conditional access capabilities are selected from a group consisting of:

(i) Powerkey, (ii) DigiCipher, (iii) VideoGuard, and (iv) a digital rights manager (DRM).

4. The method of claim 1, wherein said act of obtaining said first information comprises polling a hardware or software registry of said plurality of particular client devices to identify conditional access options.

5. The method of claim 1, wherein said network comprises a multi-channel distribution network of a hybrid fiber coax (HFC) type, and said plurality of client devices comprise one or more digital set-top boxes.

6. The method of claim 1, wherein said act of obtaining second information comprises:

providing a list of programs available for video-on-demand viewing to at least one of said plurality of particular client devices, said at least one of said plurality of particular client devices displaying said list of programs to a user thereof; and

receiving a request from said user.

7. The method of claim 1, wherein at least one of said plurality of nodes comprises a consumer premises equipment (CPE) servicing a respective plurality of locally connected devices.

8. The method of claim 7, wherein said first information is stored at said CPE.

9. An apparatus configured to control delivery of content to a plurality of client devices in a switched content delivery network, said apparatus comprising:

an interface configured to communicate with a plurality of nodes of said switched content delivery network, individual ones of said plurality of nodes being configured to service a respective plurality of client devices in communication therewith;

a storage apparatus; and

at least one microprocessor configured to run a computer program thereon, said computer program comprising a plurality of instructions which are configured to, when executed, cause said apparatus to;

receive a plurality of content from said switched content delivery network;

obtain first information related to one or more capabilities of respective ones of said plurality of client devices in communication with a particular one of said plurality of nodes;

obtain second information related to program requests from said plurality of client devices;

evaluate individual ones of said plurality of content and said obtained first information related to said one or more capabilities of said respective ones of said plurality of client devices to identify at least one of said plurality of content which is both;

(i) requested by each of said plurality of client devices, and (ii) in a format accessible by every one of said plurality of client devices; and

selectively reallocate bandwidth to accommodate delivery of said at least one of said plurality of content to said particular node.

10. The apparatus of claim 9, wherein said first information comprises information related to conditional access (CA) capabilities available to individual ones of said plurality of client devices.

11. The apparatus of claim 10, wherein said conditional access capabilities comprise at least one of:

(i) Powerkey, (ii) DigiCipher, (iii) VideoGuard, and/or (iv) a digital rights manager (DRM).
