Abstract

A method for managing media play tasks includes generating a media stack, storing current media play tasks into the media stack, and setting a play priority for each of the media play tasks, and selecting a media play task from the media stack, and playing the selected media play task. The method further includes storing a new media play task into the media stack if the new media play task is generated, and setting a play priority for the new media play task, suspending the media play task being played if the play priority of the new media play task is not lower than the play priority of the media play task being played, and playing the new media play task. A system performing the method and storage medium supporting instructions for executing the method are also provided.

Claims

1. A method for managing media play tasks in a handheld electronic device, the method comprising:

(a) generating a media stack in an operating system of the handheld device;

(b) storing current media play tasks into the media stack, and setting a play priority for each of the media play tasks;

(c) reading all media play tasks having a top play priority, and further selecting a media play task having first entered the media stack from the read media play tasks having the top play priority;

(d) playing a first media file corresponding to the selected media play task;

(e) determining if a new media play task is generated during execution of the first media file;

(f) storing the new media play task into the media stack if the new media play task is generated, and setting a play priority for the new media play task according to a type of the new media play task;

(g) determining if the play priority of the new media play task is lower than the play priority of the selected media play task; and

(h) suspending execution of the first media file if the play priority of the new media play task is not lower than the play priority of the selected media play task, and playing a second media file corresponding to the new media play task.

2. The method according to claim 1, after step (h) further comprising:

(i) determining if execution of a current media file is complete;

(g) deleting the media play task corresponding to the current media file from the media stack if the execution of the current media file is complete;

(k) determining if there are any media play tasks in the media stack; and

(l) returning to step (c) if there is a media play task in the media stack.

3. The method according to claim 2, wherein step (i) is executed if no new media play task is generated in step (e) or the play priority of the new media play task is lower than the play priority of the selected media play task in step (g).

4. The method according to claim 2, wherein step (e) is executed upon determination that the execution of the current media file is not complete in step (i).

5. A storage medium having stored thereon instructions that, when executed by a processor of a handheld device, causes the processor to perform a method for managing media play tasks in the handheld device, the method comprising:

(a) generating a media stack in an operating system of the handheld device;

(b) storing current media play tasks into the media stack, and setting a play priority for each of the media play tasks;

(c) reading all media play tasks having a top play priority, and further selecting a media play task having first entered the media stack from the read media play tasks having top play priority;

(d) playing a first media file corresponding to the selected media play task;

(e) determining if a new media play task is generated during execution of the first media file;

(f) storing the new media play task into the media stack if the new media play task is generated, and setting a play priority for the new media play task according to a type of the new media play task;

(g) determining if the play priority of the new media play task is lower than the play priority of the selected media play task; and

(h) suspending execution of the first media file if the play priority of the new media play task is not lower than the play priority of the selected media play task, and playing a second media file corresponding to the new media play task.

6. The storage medium according to claim 5, wherein the medium is selected from the group consisting of a hard disk drive, a compact disc, a digital video disc, and a tape drive.

7. A system for managing media play tasks, comprising:

a generating module configured for generating a media stack in an operating system of a handheld device;

a storing module configured for storing current media play tasks into the media stack;

a setting module configured for setting a play priority for each of the media play tasks;

a selecting module configured for reading all media play tasks having a top play priority, and further selecting a media play task first enters the media stack from the read media play tasks having the top play priority;

a playing module configured for playing a first media file corresponding to the selected media play task;

a determining module configured for determining if a new media play task is generated during execution of the first media file;

the storing module further configured for storing the new media play task into the media stack if the new media play task is generated;

the setting module further configured for setting a play priority for the new media play task according to a type of the new media play task;

the determining module further configured for determining if the play priority of the new media play task is lower than the play priority of the selected media play task; and

the playing module further configured for suspending execution of the first media file if the play priority of the new media play task is not lower than the play priority of the selected media play task, and playing a second media file corresponding to the new media play task.

8. The system according to claim 7, further comprising a deleting module, wherein:

the determining module is further configured for determining if execution of a current media file is complete; and

the deleting module is configured for deleting the media play task corresponding to the current media file from the media stack if execution of the current media file is complete.

9. The system according to claim 8, wherein:

the determining module is further configured for determining if any media play tasks are present in the media stack; and

the selecting module further configured for selecting a subsequent media play task from the media stack if a media play task is present in the media stack.

10. The system according to claim 7, wherein the handheld device is selected from the group consisting of a cell phone, a digital camera, and a personal digital assistant (PDA).
