Abstract

A set top terminal includes a processor and a runtime execution engine adapted to run on the processor. The runtime execution engine has at least one interface to expose one or more functions of the runtime execution engine. The set top terminal also includes a software application adapted to run on the runtime execution engine. An application interface shim is also provided to chain calls between the software application and the runtime execution engine and to redirect select functions calls over a communications network to a remote device. The select function calls enable at least one feature not otherwise available to the software application.

Claims

1. A set top terminal, comprising:

a processor;

a runtime execution engine adapted to run on the processor, the runtime execution engine having at least one interface to expose one or more functions of the runtime execution engine;

a software application adapted to run on the runtime execution engine; and

an application interface shim to chain calls between the software application and the runtime execution engine and redirect select functions calls over a communications network to a remote device, wherein the select function calls enable at least one feature not otherwise available to the software application.

2. The set top terminal of claim 1 wherein the software application is a DVR application.

3. The set top terminal of claim 2 wherein the remote device includes a DVR and the at least one feature enabled by the select function calls includes remote rendering.

4. The set top terminal of claim 2 wherein the remote device includes a remote set top terminal and the at least one feature enabled by the select function calls includes remote rendering and remote recording.

5. The set top terminal of claim 1 wherein the application interface shim is adapted to return a java media framework player from the remote device to the software application in response to a select call from the software application.

6. The set top terminal of claim 1 wherein the runtime execution engine is OCAP HN compliant.

7. The set top terminal of claim 1 wherein the runtime execution engine includes a Java virtual machine.

8. The set top terminal of claim 1 wherein the interface exposing the runtime execution engine is an application program interface (API) and the calls chained between the software application and the runtime execution engine are API calls.

9. The set top terminal of claim 1 wherein the software application is adapted to call non-networking APIs associated with the runtime execution engine and not networking APIs associated with the runtime execution engine.

10. The set top terminal of claim 1 wherein the at least one feature enabled by the select function calls includes network-enabled features.

11. A computer-readable storage medium containing instructions which, when performed by one or more processors disposed in an electronic device, performs a method comprising:

receiving a function call from a non-network enabled software application to render in a selected rendering state content available on a remotely located device;

re-directing the function call along a code path over a communications network to an execution engine residing on the remotely located device; and

in response to the re-directed function call, receiving the selected content in the selected rendering state.

12. The computer-readable medium of claim 11 further comprising receiving over the code path a media player through which the content is rendered in the selected rendering state.

13. The computer-readable medium of claim 11 wherein the selected rendering state is selected from the group consisting of pause, play, rewind and fast-forward.

14. The computer-readable medium of claim 11 wherein the function call is an API call.

15. The computer-readable medium of claim 11 wherein the software application is a DVR application and the remotely located device includes a DVR.

16. A method of enhancing features offered by a software application operable on a network-enabled set top terminal, comprising:

installing the software application on the network-enabled set top terminal, the set top terminal having a software stack that includes an execution engine; and

providing an API shim between the software application and the execution engine, wherein the API shim is configured to redirect select API calls to an external resource capable of performing functions of which the execution engine is incapable and which enable at least one enhanced feature accessible to a user through the software application.

17. The method of claim 16 wherein the API shim is further configured to receive a software object from the external resource and forward the software object to the software application so that the enhanced feature can be enabled.

18. The method of claim 17 wherein the software object is a media player.

19. The method of claim 16 wherein the software stack is an OCAP software stack having OCAP HN extensions.
