Abstract

A mobile multimedia framework API is provided that is capable of operation in mobile hardware devices. The mobile multimedia framework API includes a playback interface, controls, an event listener, an error list, exceptions, events, control types, and protocol handlers. Advantageously, a memory size of the mobile multimedia framework API is less than 100 kilobytes.

Claims

1. A mobile multimedia framework application program interface (API) capable of operation in mobile hardware devices, the mobile multimedia framework API consisting of:

a playback interface, a control interface, an event listener interface, an error list interface, an exceptions interface, an events interface, and a protocol handler interface,

wherein a memory size of the mobile multimedia framework API is less than 100 kilobytes.

2. A mobile multimedia framework API as recited in claim 1, wherein the playback interface is a top-level entry point to the API for an application.

3. A mobile multimedia framework API as recited in claim 2, wherein the playback interface further defines start and stop playback functionality.

4. A mobile multimedia framework API as recited in claim 1, wherein the control interface defines advance playback functions.

5. A mobile multimedia framework API as recited in claim 1, wherein the event listener interface defines objects to receive update events from players.

6. A mobile multimedia framework API as recited in claim 1, wherein the error list interface defines error classes for the API.

7. A mobile multimedia framework API as recited in claim 1, wherein the exceptions interface defines exception classes for the API.

8. A mobile multimedia framework API as recited in claim 1, wherein the protocol handler interface defines classes to handle data delivery protocols.

9. A mobile multimedia framework application program interface (API) capable of operation in mobile hardware devices, the mobile multimedia framework API comprising:

a playback interface consisting of a manager API, a package manager API, a player API, a time API, a time base API, a system time base API, and a media locator API;

an event listener interface; and

a protocol handler interface, wherein a memory size of the mobile multimedia framework API is less than 100 kilobytes.

11. A mobile multimedia framework API as recited in claim 9, wherein the protocol handler interface defines classes to handle data delivery protocols.

12. A mobile multimedia framework API as recited in claim 9, further comprising a control interface.

13. A mobile multimedia framework API as recited in claim 12, wherein the control interface defines advance playback functions.

14. A mobile multimedia framework API as recited in claim 9, further comprising an error list interface.

15. A mobile multimedia framework API as recited in claim 14, wherein the error list interface defines error classes for the API.

16. A mobile multimedia framework API as recited in claim 9, further comprising an exceptions interface.

17. A mobile multimedia framework API as recited in claim 16, wherein the exceptions interface defines exception classes for the API.

19. A mobile multimedia framework API as recited in claim 18, further comprising an exceptions interface.

20. A mobile multimedia framework API as recited in claim 19, wherein the exceptions interface defines exception classes for the API.

18. A mobile multimedia framework application program interface (API) capable of operation in mobile hardware devices, the mobile multimedia framework API comprising:

a playback interface consisting of a manager API, a package manager API, a player API, a time API, a time base API, a system time base API, and a media locator API;

an event listener interface that defines objects to receive update events from players; and

a protocol handler interface that defines classes to handle data delivery protocols, wherein a memory size of the mobile multimedia framework API is less than 100 kilobytes.
