Abstract

Network based just-in-time compilation based on A Priori knowledge of a set of disparate clients is disclosed. One embodiment comprises using a web service to register a device and store a device profile containing the capabilities of the device, receiving a request from the device to subscribe to a content service, and to create a client runtime for the device for a requested service corresponding to the device capabilities. In this way, the embodiment may send the client runtime to the device to allow the device to communicate with the content service through the web service.

Claims

1. A method of providing network based just-in-time compilation, the method comprising:

registering a device having a device profile containing device capabilities, the device being registered with a web service;

receiving a request from the device to subscribe to a content service;

creating a client runtime for the device corresponding to the device capabilities contained in the device profile; and

sending the client runtime to the device to provide functionality for the device to communicate with the content service through the web service.

2. The method of claim 1, further comprising:

associating at least one user identity corresponding to a plurality of services with the device; and

logging in to at least one of the plurality of services in response to a device authentication.

3. The method of claim 2, further comprising:

providing a service directory on the device corresponding to the plurality of services; and

creating a client runtime for the device corresponding to at least one of the plurality of services in the service directory in response to a subscription request.

4. The method of claim 1, further comprising:

connecting the device with the content service; and

providing additional functionality to the device to communicate with the content service in response to a pluggable request handler on the device.

5. The method of claim 4, wherein the additional functionality includes at least one of media transcription, content caching, or protocol conversion.

6. The method of claim 1, wherein registering the device further comprises storing the device profile.

7. The method of claim 1, wherein the device capabilities includes at least one of a device capability at a user interface level, a transport level, or a protocol level.

8. The method of claim 1, wherein registering a device having a device profile containing device capabilities involves registering a first device having a first device profile, the method further comprising:

registering a second device having a second device profile; and

creating a client runtime for the second device corresponding to a device capability contained in the second device profile.

9. A system for network based just-in-time (JIT) compilation, the system comprising:

a web service to register a device and store a device profile comprising device capabilities in memory;

a protocol endpoint to receive a request from the device to subscribe to a content service;

a runtime service to create a client runtime for the device corresponding to the device capabilities contained in the device profile, the client runtime configured to communicate with the content service when run on the device; and

a communication service to provide communication between the client runtime on the device and the content service.

10. The system of claim 9, wherein the web service further comprises an identity service to associate at least one user identity corresponding to a plurality of services with the device, wherein the web service uses the identity service to log in to at least one of the plurality of services in response to a device authentication.

11. The system of claim 10, wherein the web service is configured to provide a service directory corresponding to the plurality of services, and the runtime service is configured to create a client runtime for the device corresponding to at least one of the plurality of services in the service directory in response to a subscription request.

12. The system of claim 11, wherein the runtime service is further configured to create a client runtime for the device corresponding to a user selected group of services out of the plurality of services in the service directory.

13. The system of claim 9, further comprising a pluggable request handler to provide additional functionality to the device to communicate with the content service.

14. The system of claim 13, wherein the additional functionality includes at least one of media transcription, content caching, or protocol conversion.

15. The system of claim 9, wherein the device capabilities includes at least one of a device capability at a user interface level, a transport level, or a protocol level.

16. The system of claim 15, wherein the web service is configured to register a plurality of devices having a plurality of device profiles, and to create a corresponding plurality of client runtimes for the plurality of devices.

17. A computer-readable medium comprising instructions executable by a computing device to provide network based just-in-time compilation, the instructions being executable to perform a method comprising:

registering a device having a device profile containing device capabilities, the device being registered with a web service;

receiving a request from the device to subscribe to a content service;

creating a client runtime for the device corresponding to the device capabilities contained in the device profile;

sending the client runtime to the device to provide functionality for the device to communicate with the content service through the web service;

associating at least one user identity corresponding to a plurality of services with the device; and

logging in to at least one of the plurality of services in response to a device authentication.

18. The computer-readable medium of claim 17, further comprising instructions executable for:

providing a service directory on the device corresponding to the plurality of services; and

creating a client runtime for the device corresponding to at least one of the plurality of services in the service directory in response to a subscription request.

19. The computer-readable medium of claim 17, further comprising instructions executable for:

connecting the device with the content service; and

providing additional functionality to the device to communicate with the content service in response to a pluggable request handler on the device.

20. The computer-readable medium of claim 17, wherein registering a device having a device profile containing device capabilities involves registering a first device having a first device profile, further comprising instructions executable for:

registering a second device having a second device profile; and

creating a client runtime for the second device corresponding to a device capability contained in the second device profile.
