Abstract

Systems and methods for nonlinear media playback using a linear media player are described. In one implementation, a video tree representing a branching video presentation is provided, and a dynamic playlist is provided to a linear video player. A controller component interacts with the linear video player through a standard interface of the linear video player. During playback of a video content segment in the dynamic playlist by the linear video player, an indication of a user interaction with the playing video content segment is received by the controller component and from the linear video player via the standard interface, and the dynamic playlist is modified based on video content segments in a branch of the video tree. In another implementation, an uncompressed media file is selected and combined with a preceding and/or following media file. The combined files are compressed and a portion of the compressed file corresponding to the original media file is extracted.

Claims

1. A computer-implemented method comprising:

a) selecting an uncompressed media file;

b) identifying, based on the selected uncompressed media file, at least one of a preceding uncompressed media file and a following uncompressed media file;

c) concatenating the selected uncompressed media file and at least one of the preceding uncompressed media file and the following uncompressed media file to form a concatenated uncompressed media file;

d) compressing the concatenated uncompressed media file to form a compressed media file; and

e) selecting a portion of the compressed media file as a compressed version of the selected uncompressed media file.

2. The method of claim 1, wherein the media file comprises audio data.

3. The method of claim 1, further comprising providing a video tree comprising a plurality of branches, each branch comprising a plurality of media files.

4. The method of claim 3, wherein the identification of the at least one of the preceding uncompressed media file and the following uncompressed media file is based on a branch of the video tree.

5. The method of claim 3, further comprising performing steps a) through e) for a plurality of media files in the video tree.

6. The method of claim 3, wherein the media files in the video tree each comprise compressed audio data, the method further comprising selecting a media file from the video tree, and converting the compressed audio data of the selected media file from the video tree to uncompressed audio data, wherein the selected uncompressed media file comprises the uncompressed audio data.

7. The method of claim 1, wherein the concatenating comprises concatenating the selected uncompressed media file to the end of the preceding uncompressed media file.

8. The method of claim 1, wherein the concatenating comprises concatenating the following uncompressed media file to the end of the selected uncompressed media file.

9. The method of claim 1, further comprising storing a duration of the selected uncompressed media file, and wherein selecting the portion is based at least in part on the stored duration.

10. The method of claim 1, wherein selecting the portion comprises extracting an intermediate portion of the compressed media file, and storing the extracted intermediate portion as the compressed version of the selected uncompressed media file.

11. The method of claim 1, further comprising selecting a plurality of portions of the compressed media file as respective compressed versions of the concatenated uncompressed media files.

12. The method of claim 11, wherein playback occurs seamlessly among the compressed versions of the concatenated uncompressed media files.

13. A system comprising:

one or more computers programmed to perform operations comprising;

a) selecting an uncompressed media file;

b) identifying, based on the selected uncompressed media file, at least one of a preceding uncompressed media file and a following uncompressed media file;

c) concatenating the selected uncompressed media file and at least one of the preceding uncompressed media file and the following uncompressed media file to form a concatenated uncompressed media file;

d) compressing the concatenated uncompressed media file to form a compressed media file; and

e) selecting a portion of the compressed media file as a compressed version of the selected uncompressed media file.

14. The system of claim 13, wherein the media file comprises audio data.

15. The system of claim 13, wherein the operations further comprise providing a video tree comprising a plurality of branches, each branch comprising a plurality of media files.

16. The system of claim 15, wherein the identification of the at least one of the preceding uncompressed media file and the following uncompressed media file is based on a branch of the video tree.

17. The system of claim 15, wherein the operations further comprise performing steps a) through e) for a plurality of media files in the video tree.

18. The system of claim 15, wherein the media files in the video tree each comprise compressed audio data, and wherein the operations further comprise selecting a media file from the video tree, and converting the compressed audio data of the selected media file from the video tree to uncompressed audio data, wherein the selected uncompressed media file comprises the uncompressed audio data.

19. The system of claim 13, wherein the concatenating comprises concatenating the selected uncompressed media file to the end of the preceding uncompressed media file.

20. The system of claim 13, wherein the concatenating comprises concatenating the following uncompressed media file to the end of the selected uncompressed media file.

21. The system of claim 13, wherein the operations further comprise storing a duration of the selected uncompressed media file, and wherein selecting the portion is based at least in part on the stored duration.

22. The system of claim 13, wherein selecting the portion comprises extracting an intermediate portion of the compressed media file, and storing the extracted intermediate portion as the compressed version of the selected uncompressed media file.

23. The system of claim 13, wherein the operations further comprise selecting a plurality of portions of the compressed media file as respective compressed versions of the concatenated uncompressed media files.

24. The system of claim 23, wherein playback occurs seamlessly among the compressed versions of the concatenated uncompressed media files.
