Abstract

Methods and apparatus for extending the capabilities of a client device (e.g., consumer premises equipment in a cable network) using one or more on-demand applications. In one aspect, an improved media handling extension is provided within the device with which the various application(s) can interface to facilitate on-demand interaction between the CPE and the head end or other network entity. In one exemplary embodiment, the client device comprises a digital set-top box (DSTB) having Java-enabled middleware adapted to implement the OCAP/ACAP/MHP mandated Java Media Framework (JMF) APIs. A specially configured application is downloaded to the DSTB and run, the application configuring the paths within the device to provide, inter alia, media access to the on-demand application(s) according to one or more network specific protocols. Accordingly, the network MSO can also uniquely configure the CPE within its network for on-demand capability according to its own specific protocols from the head-end. Improved client device and head-end configurations, as well as methods of operating these systems, are also disclosed.

communicate between said CPE and another entity of said network;

process the content delivered to said CPE; and

enable a user of said CPE to control, via a user interface, playback of said content according to said network-specific protocol;

wherein at least one of said plurality of components comprises a shared component which is utilized by one or more second applications also having permissions from an OCAP monitor and simultaneously running on said CPE.

3. The CPE of claim 2, wherein said CPE comprises a digital settop box (DSTB) with Java-based middleware, and said at least one first software application comprises at least one class and at least one interface disposed within an application directory hierarchy.

4. The CPE of claim 3, wherein said CPE:

receives said at least one first application over said network; and

subsequent to said receipt, launches said at least one first application to configure at least one path to at least one of said plurality of components.
