Synchronizing text-to-audio with interactive videos in the video framework

1. An interactive video playing device, comprising:

a memory operable to store:

a video timing map comprising a plurality of timestamps, wherein each timestamp is associated with a source scene identifier for a video scene and an animation identifier for an animation; and

an audio sample buffer comprising a plurality of audio samples; and

a processor operably coupled to the memory, and configured to:

determine a time on a progress bar;

identify a timestamp in the video timing map based on the time on the progress bar;

identify a source scene identifier corresponding with the identified timestamp;

play a video scene corresponding with the identified source scene identifier;

identify a first animation identifier corresponding with the identified timestamp;

play a first animation associated with the first animation identifier;

play a first audio sample associated with the first animation.

2. The device of claim 1 , wherein the processor is further configured to:

determine the source scene identifier is associated with a background audio sample; and

play the background audio sample before playing the first animation.

3. The device of claim 2 , wherein the processor is further configured to reduce an audio level for the background audio sample before playing the first audio sample.

4. The device of claim 1 , wherein the processor is configured to:

determine that a second animation is scheduled to be played while the first animation is playing; and

play the second animation while the first animation is playing.

5. The device of claim 4 , wherein the processor is further configured to continue playing the first audio sample while the second animation is playing.

6. The device of claim 1 , wherein the processor is further configured to:

determine a second animation that is associated with the video scene is scheduled to be played before the first animation; and

play the second animation before playing the first animation.

7. The device of claim 1 , wherein identifying a timestamp in the video timing map comprises identifying a closest timestamp that precedes the time on the progress bar.

8. An interactive video playing method, comprising:

determining a time on a progress bar;

identifying a timestamp in a video timing map based on the time on the progress bar, wherein:

the video timing map comprising a plurality of timestamps; and

each timestamp is associated with a source scene identifier for a video scene and an animation identifier for an animation;

identifying a source scene identifier corresponding with the identified timestamp;

playing a video scene corresponding with the identified source scene identifier;

identifying a first animation identifier corresponding with the identified timestamp;

playing a first animation associated with the first animation identifier;

playing a first audio sample from an audio sample buffer, wherein the first audio sample is associated with the first animation.

9. The method of claim 8 , further comprising:

determining the source scene identifier is associated with a background audio sample; and

playing the background audio sample before playing the first animation.

10. The method of claim 9 , further comprising reducing an audio level for the background audio sample before playing the first audio sample.

11. The method of claim 8 , further comprising:

determining that a second animation is scheduled to be played while the first animation is playing; and

playing the second animation while the first animation is playing.

12. The method of claim 11 , further comprising continuing to play the first audio sample while the second animation is playing.

13. The method of claim 8 , further comprising:

determining a second animation that is associated with the video scene is scheduled to be played before the first animation; and

playing the second animation before playing the first animation.

14. The method of claim 8 , wherein identifying a timestamp in the video timing map comprises identifying a closest timestamp that precedes the time on the progress bar.

15. A computer program comprising executable instructions stored in a non-transitory computer readable medium that when executed by a processor causes the processor to:

determine a time on a progress bar;

identify a timestamp in a video timing map based on the time on the progress bar, wherein:

the video timing map comprising a plurality of timestamps; and

each timestamp is associated with a source scene identifier for a video scene and an animation identifier for an animation;

identify a source scene identifier corresponding with the identified timestamp;

play a video scene corresponding with the identified source scene identifier;

identify a first animation identifier corresponding with the identified timestamp;

play a first animation associated with the first animation identifier; and

play a first audio sample from an audio sample buffer, wherein the first audio sample is associated with the first animation.

16. The computer program of claim 15 , further comprising instructions that when executed by the processor causes the processor to:

determine the source scene identifier is associated with a background audio sample; and

play the background audio sample before playing the first animation.

17. The computer program of claim 16 , further comprising instructions that when executed by the processor causes the processor to reduce an audio level for the background audio sample before playing the first audio sample.

18. The computer program of claim 15 , further comprising instructions that when executed by the processor causes the processor to:

determine that a second animation is scheduled to be played while the first animation is playing; and

play the second animation while the first animation is playing.

19. The computer program of claim 18 , further comprising instructions that when executed by the processor causes the processor to continue playing the first audio sample while the second animation is playing.

20. The computer program of claim 15 , further comprising instructions that when executed by the processor causes the processor to:

determine a second animation that is associated with the video scene is scheduled to be played before the first animation; and

play the second animation before playing the first animation.
