Abstract

A method, system, apparatus, and computer program product for optimizing power consumption in special media playback scenarios. The method includes identifying a scenario where decoding of a first portion of a multimedia stream can be interrupted; and interrupting the decoding of the first portion of the multimedia stream while continuing to decode a second portion of the multimedia stream. The first portion may be a video stream and the second portion may be an audio stream, and the scenario may include a playback window for the video stream being hidden. The first portion may be an audio stream and the second portion may be a video stream, and the scenario may include the audio stream being muted. The method may further include determining that the scenario has changed and resuming decoding of the first portion of the multimedia stream.

Claims

1. A computer-implemented method comprising:

identifying a scenario where decoding of a first portion of an multimedia stream can be interrupted;

interrupting the decoding of the first portion of the multimedia stream while continuing to decode a second portion of the multimedia stream.

2. The method of claim 1 wherein

the first portion is a video stream and the second portion is an audio stream;

and

the scenario includes a playback application for the video stream being hidden.

3. The method of claim 1 wherein

the first portion is an audio stream and the second portion is a video stream;

and

the scenario includes the audio stream being muted.

4. The method of claim 1 further comprising:

determining that the scenario has changed; and

resuming decoding of the first portion of the multimedia stream.

5. The method of claim 4 wherein resuming decoding of the first portion of the multimedia stream comprises:

identifying a first frame currently being decoded in the second portion of the multimedia stream;

identifying a second frame in the first portion of the multimedia stream, the second frame corresponding to the first frame; and

resuming rendering of the first portion of the multimedia stream with the second frame.

6. A system comprising:

at least one processor; and

a memory coupled to the at least one processor, the memory comprising instructions for performing the following;

identifying a scenario where decoding of a first portion of an multimedia stream can be interrupted;

interrupting the decoding of the first portion of the multimedia stream while continuing to decode a second portion of the multimedia stream.

7. The system of claim 6 wherein

the first portion is a video stream and the second portion is an audio stream;

and

the scenario includes a playback application for the video stream being hidden.

8. The system of claim 6 wherein

the first portion is an audio stream and the second portion is a video stream;

and

the scenario includes the audio stream being muted.

9. The system of claim 6 wherein the instructions further comprise instructions for performing the following:

determining that the scenario has changed; and

resuming decoding of the first portion of the multimedia stream.

10. The system of claim 9 wherein resuming decoding of the first portion of the multimedia stream comprises:

identifying a first frame currently being decoded in the second portion of the multimedia stream;

identifying a second frame in the first portion of the multimedia stream, the second frame corresponding to the first frame; and

resuming rendering of the first portion of the multimedia stream with the second frame.

11. A computer program product comprising:

a computer-readable storage medium; and

instructions in the computer-readable storage medium, wherein the instructions, when executed in a processing system, cause the processing system to perform operations comprising;

identifying a scenario where decoding of a first portion of an multimedia stream can be interrupted;

interrupting the decoding of the first portion of the multimedia stream while continuing to decode a second portion of the multimedia stream.

12. The computer program product of claim 11 wherein

the first portion is a video stream and the second portion is an audio stream;

and

the scenario includes a playback application for the video stream being hidden.

13. The computer program product of claim 11 wherein

the first portion is an audio stream and the second portion is a video stream;

and

the scenario includes the audio stream being muted.

14. The computer program product of claim 11 wherein the instructions further cause the processing system to perform operations comprising:

determining that the scenario has changed; and

resuming decoding of the first portion of the multimedia stream.

15. The computer program product of claim 14 wherein resuming decoding of the first portion of the multimedia stream comprises:

identifying a first frame currently being decoded in the second portion of the multimedia stream;

identifying a second frame in the first portion of the multimedia stream, the second frame corresponding to the first frame; and

resuming rendering of the first portion of the multimedia stream with the second frame.
