Methods and apparatus for device capabilities discovery and utilization within a content-based network
Methods and apparatus for determining and selecting digital coding and/or decoding technology, delivery bitrates, and resolution parameters 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 display resolution, bitrate, and/or decoding capabilities profiles. The server determines the one or more capabilities possessed by the CPE or client device, and evaluates one or more program or content choices for possible delivery to that CPE or device based on its profile. The selection process may also take into consideration network and/or CPE operational considerations, such as conservation of downstream bandwidth, CPE uprating capability, client device power consumption, and the like.

generate profile data relating to said video display resolution capabilities for transmission to a network entity;
transmit a request for one or more of a plurality of content elements in standard definition (SD) display resolution to said network; and
receive said requested one or more of said plurality of content elements as a multicast distributed at least to said networked apparatus and at least one other networked apparatus, said networked apparatus and said at least one other networked apparatus sharing at least a high definition (HD) video display resolution capability, said requested one or more of said plurality of content elements being transmitted according to said high definition (HD) display resolution.
7. The apparatus as set forth in claim 6 , wherein said at least one computer program is further configured to generate and transmit a video display resolution capability message using a session-based protocol.
8. The apparatus as set forth in claim 6 , further comprising a radio frequency (RF) interface for at least receiving modulated digital RF signals from said network.
9. The apparatus as set forth in claim 6 , wherein said at least one computer program is rendered using an object oriented programming language.
10. The apparatus as set forth in claim 6 , wherein said networked apparatus comprises a mobile device configured communicate with a set-top box adapted for use in cable television network.
11. The apparatus as set forth in claim 6 , wherein said networked apparatus comprises a mobile device in data communication with a DOCSIS cable modem adapted for use in cable television network.
