Abstract

An exemplary method includes detecting a request to launch an application on a device, accessing metadata associated with the application over a network, using the metadata to determine whether sufficient resources are available to launch the application on the device, and performing at least one action based on said determination. The at least one action may include launching the application on the device when sufficient resources are available or blocking a launch of the application on the device when sufficient resources are not available. In certain embodiments, the method is performed by the device. In certain embodiments, the device includes a set-top box configured to access a media service over the network. Corresponding methods, systems, apparatuses, and computer-readable media are also disclosed.

Claims

1. A method comprising:

detecting a request to launch an application on a device;

accessing metadata associated with said application over a network;

using said metadata to determine whether sufficient resources are available to launch said application on said device; and

performing at least one action based on said determination.

2. The method of claim 1, wherein said detecting, said accessing, said using, and said performing are performed by said device.

3. The method of claim 2, wherein said device comprises a set-top box configured to access at least one media service over said network.

4. The method of claim 1, wherein said sufficient resources are determined not to be available to launch said application on said device, and said at least one action comprises blocking said launch of said application on said device.

5. The method of claim 4, wherein said blocking said launch comprises blocking a request to download data representative of said application to said device over said network.

6. The method of claim 1, wherein said sufficient resources are determined not to be available to launch said application on said device, and said at least one action comprises attempting to release at least one of said resources on said device.

7. The method of claim 6, wherein said at least one action further comprises:

releasing said at least one of said resources on said device; and

using said metadata to again determine whether sufficient resources are available to launch said application on said device.

8. The method of claim 1, wherein said sufficient resources are determined to be available to launch said application on said device, and said at least one action comprises launching said application for execution on said device.

9. The method of claim 8, wherein said launching comprises:

downloading data representative of said application over said network;

loading said data representative of said application; and

initiating execution of said application on said device.

10. The method of claim 9, wherein said downloaded application includes a development library vector table linked to a development library, and wherein said loading comprises overriding said development library vector table with a resident vector table linked to a resident library.

11. The method of claim 10, further comprising routing a function call initiated by said application from said development library to said resident library.

12. The method of claim 9, further comprising:

receiving a notification of a termination of execution of said application on said device; and

releasing device resources allocated to said application.

13. The method of claim 9, wherein said loading comprises loading said data representative of said downloaded application directly into non-permanent memory for said execution on said device.

14. The method of claim 9, wherein said data representative of said application comprises executable code native to said device.

15. The method of claim 9, further comprising:

running a resident service access module on said device; and

passing control of said device from said resident service access module to said application for said execution of said application on said device.

16. The method of claim 1, further comprising:

tracking usage of device resources on said device; and

using said tracked usage of said device resources together with said metadata to determine whether sufficient resources are available to launch said application on said device.

17. The method of claim 1, tangibly embodied as computer-executable instructions on at least one computer-readable medium.

18. An apparatus comprising:

at least one processor;

a computer-readable medium communicatively coupled to said at least one processor;

a resident service access module tangibly embodied on said computer-readable medium, said resident service access module configured to direct said at least one processor to access at least one media service provided by a media content service provider over a network; and

an application launcher module tangibly embodied on said computer-readable medium, said application launcher module configured to direct said at least one processor to;

detect a request to launch an application,

access metadata for said application over said network,

use said metadata to determine whether sufficient resources are available to launch said application on said device, and

perform at least one action based on said determination.

19. The apparatus of claim 18, wherein said application launcher module is configured to direct said at least one processor to launch said application on said device when said sufficient resources are determined to be available to launch said application on said device.

20. The apparatus of claim 19, wherein said application launcher module is configured to direct said at least one processor to launch said application within an operational context of said resident service access module.

21. The apparatus of claim 19, wherein said launch comprises said application launcher module directing said at least one processor to pass control of said device from said resident service access module to said application.

22. The apparatus of claim 19, wherein said application launcher module is configured to direct said at least one processor to return said control of said device from said application to said resident service access module in response to a termination of said application.

23. A system comprising:

a media content provider subsystem configured to provide a media service and maintain application data representative of an application and application metadata descriptive of said application;

a resident service access facility within a media content processing subsystem, said resident service access facility configured to access said media service over a network; and

an application launcher facility within said media content processing subsystem, said application launcher facility configured to;

detect a request to launch said application on said media content processing subsystem,

access said application metadata descriptive of said application over said network,

use said application metadata to determine whether sufficient resources are available to launch said application on said media content processing subsystem, and

perform at least one action based on said determination.

24. The system of claim 23, wherein when said application launcher facility determines that sufficient resources are available to launch said application on said media content processing subsystem, said application launcher facility:

downloads said data representative of said application to said media content processing subsystem over said network;

loads said data representative of said application in memory of said media content processing subsystem; and

initiates execution of said application on said media content processing subsystem.
