Abstract

A media player is executed on an electronic device by implementing a runtime of a media player in a modular framework on the electronic device. The modular framework is configured to have each of multiple types of media player runtimes implemented therein and to host modules that configure any of the types of media player runtimes for respective device types. The runtime is configured for the electronic device using a module hosted by the modular framework. The module abstracts at least one resource in the electronic device available to the media player. The electronic device is prepared for execution of the media player on the electronic device, and the media player uses the resource during the execution based on configuration according to the module.

Claims

1. A computer-implemented method comprising:

implementing a runtime of a media player in a modular framework on an electronic device, the modular framework being configured to have each of multiple types of media player runtimes implemented therein and to host modules that configure any of the types of media player runtimes for respective device types;

configuring the runtime for the electronic device using a module of the modular framework, the module abstracting at least one resource in the electronic device available to the media player; and

preparing the media player for execution, the media player using the resource during the execution based on configuration according to the module.

2. The computer-implemented method of claim 1, wherein the modules are created using code that is object oriented according to object-oriented programming, and wherein the modular framework is not object oriented.

3. The computer-implemented method of claim 2, wherein the modular framework prevents cascading dependencies between the modules.

4. The computer-implemented method of claim 1, wherein the modular framework models an abstract machine and the runtime is ported to the abstract machine.

5. The computer-implemented method of claim 4, wherein the module abstracts device hardware of the electronic device.

6. The computer-implemented method of claim 5, wherein the device hardware includes at least one hardware selected from:

an audio decoder;

a video decoder;

an image decoder;

a graphics scaler;

a video scaler;

a display compositor;

a 2D, 3D or video graphics accelerator;

an input and output connector; and

combinations thereof.

7. The computer-implemented method of claim 4, wherein at least one of the modules abstracts local multimedia capability of the electronic device.

8. The computer-implemented method of claim 4, wherein the local multimedia capability includes at least one capability selected from:

a media source;

a media item;

a media stream;

a media player; and

combinations thereof.

9. The computer-implemented method of claim 1, wherein at least one of the modules exports one interface class and wherein an interface according to the interface class is used in configuring the runtime for the electronic device.

10. The computer-implemented method of claim 1, wherein the media player requests a function of the electronic device by acquiring the module.

11. The computer-implemented method of claim 1, wherein each of the modules is self-contained without static linkage dependency on any other module.

12. The computer-implemented method of claim 1, wherein at least one of the modules is self-contained and statically linked into a single assembly of the modular framework.

13. The computer-implemented method of claim 1, wherein a source code of the module is self contained within the module.

14. The computer-implemented method of claim 1, wherein at least one of the modules represents a software library that the media player can call using the runtime.

15. The computer-implemented method of claim 1, wherein the modular framework is configured so that all resources including the resources of the electronic device are optional.

16. The computer-implemented method of claim 15, wherein another resource is made available to the media player by hosting another of the modules in the modular framework without otherwise adapting the modular framework and the module.

17. The computer-implemented method of claim 1, wherein implementing the runtime in the modular framework makes the media player platform independent.

18. The computer-implemented method of claim 1, wherein configuring the runtime using the module makes the electronic device independent of version of the media player.

19. The computer-implemented method of claim 1, wherein the electronic device includes at least one device selected from:

a computer;

a handheld device;

a consumer electronics device;

a television;

a set-top box;

an appliance;

an electronic picture frame;

a cellular telephone;

a gaming device; and

combinations thereof.

20. The computer-implemented method of claim 19, wherein the electronic device includes a television operated by a system-on-a-chip, further comprising implementing the modular framework in the system.

21. The computer-implemented method of claim 19, wherein a media provider uses the media player also to provide content online, and wherein the modular framework allows the media provider to use the media player also to provide the content using the television.

22. A computer program product tangibly embodied in a tangible program carrier and comprising instructions that when executed by a processor perform a method comprising:

implementing a runtime of a media player in a modular framework on an electronic device, the modular framework being configured to have each of multiple types of media player runtimes implemented therein and to host modules that configure any of the types of media player runtimes for respective device types;

configuring the runtime for the electronic device using a first module of the modular framework, the first module abstracting at least one resource in the electronic device available to the media player; and

preparing the media player for execution, the media player using the resource during the execution based on configuration according to the first module.

23. A system comprising:

an electronic device configured to present media output to a user; and

a computer-readable medium accessible to the electronic device and comprising;

a modular framework configured for having each of multiple types of media player runtimes implemented therein and for hosting modules that configure any of the multiple types of media player runtimes for respective device types; and

a runtime of a media player implemented in the modular framework, the runtime configured for the electronic device by a module hosted by the modular framework, the module abstracting at least one resource in the electronic device available to the media player.

24. The system of claim 23, wherein the runtime includes:

a first library comprising built-in classes available to a programmer of the media player in multiple versions of the modular framework;

a second library that abstracts device-specific notions and allows the media player to work with corresponding multimedia objects; and

a third library providing for specific extensions not covered by the first and second library.

25. The system of claim 23, wherein the modular framework includes an application manager that allows multiple applications using the media player to be instantiated and run on the electronic device.

26. The system of claim 23, wherein the modular framework includes a library that allows a programmer of the media player access to device configuration and control for the electronic device independent of a type of the electronic device.
