Abstract

Preferred implementations of the invention permit a user to seamlessly switch from a first media stream to a second media stream in a synchronized way, such that the second media stream picks up where the first media stream left off. In this way, the user experiences events chronologically but without interruption. In a preferred implementation, a user watching a skim video switches to a full length video when, for example, the skim video reaches a frame that is of particular interest to the user. The full length video begins at a point corresponding to the frame in the skim video that is of interest to the user, without skipping over video segments, so that the user does not experience any time gaps in the story line.

Claims

1. A method of browsing, comprising:

accessing a first media stream;

allowing the first media stream to play up to some point in the first media stream; and

switching media streams by selecting a second media stream different from the first media stream, said selecting thereby starting the second media stream at a point corresponding to said point in the first media stream.

2. The method of claim 1, wherein the second media stream has media content in common with the first media stream.

3. The method of claim 1, wherein the second media stream includes a full video.

4. The method of claim 1, wherein one of the media streams includes audio.

5. The method of claim 1, wherein one of the media streams includes closed caption text.

6. The method of claim 1, wherein one of the media streams is selected from the group consisting of skim video, moving storyboard, full video, audio, text, animation, and graphics.

7. The method of claim 1, said switching comprising clicking on a mouse or depressing a key on a keyboard.

8. The method of claim 1, wherein said point in the second media stream is selected from one of a plurality of points in the second media stream corresponding to the first media stream.

9. The method of claim 1, wherein said point in the second media stream corresponds in the chronological sense to said point in the first media stream.

10. The method of claim 9, wherein the first media stream includes a skim video and the second media stream includes a full video.

11. The method of claim 9, wherein one of the media streams is dedicated to audio.

12. The method of claim 9, wherein one of the media streams is sped-up audio.

13. The method of claim 9, wherein one of the media streams includes text.

14. The method of claim 9, wherein one of the media streams is dedicated to closed caption text.

15. The method of claim 9, wherein one of the media streams includes moving storyboard with fast or slow audio.

16. The method of claim 9, wherein one of the media streams includes both audio and video.

17. The method of claim 9, wherein one of the media streams includes video, and the rate at which the video is streamed out is controlled by a user.

18. The method of claim 9, wherein one of the media streams includes a low bandwidth video stream.

19. The method of claim 9, wherein said starting point in the second media stream is determined by accessing a look-up table.

20. The method of claim 9, wherein said starting point in the second media stream is determined from a mathematical formula.

21. The method of claim 9, wherein said starting point in the second media stream is computed from data which is streamed with the first media stream.

22. The method of claim 9, wherein said starting point in the second media stream compensates for user response time and thus is not precisely synchronized with said point in the first media stream.

23. The method of claim 9, wherein any synchronization mismatch between said first and second points is less than about 3 seconds of viewing time.

24. The method of claim 9, wherein said starting point in the second media stream corresponds to the beginning of a shot or a video scene.

25. The method of claim 9, wherein said starting point in the second media stream corresponds to the beginning of a sentence.

26. The method of claim 9, wherein one of the media streams includes more than one track.

28. The method of claim 27, wherein the second media stream has media content in common with the first media stream.

29. The method of claim 27, wherein the second media stream includes a full video.

30. The method of claim 27, wherein one of the media streams includes audio.

31. The method of claim 27, wherein one of the media streams includes closed caption text.

32. The method of claim 27, wherein said point in the second media stream corresponds in the chronological sense to said point in the first media stream.

33. The method of claim 32, wherein the first media stream includes a skim video and the second media stream includes a full video.

34. The method of claim 32, wherein one of the media streams is dedicated to audio.

35. The method of claim 32, wherein one of the media streams includes text.

36. The method of claim 32, wherein one of the media streams includes both audio and video.

37. The method of claim 32, wherein said starting point in the second media stream compensates for user response time and thus is not precisely synchronized with said point in the first media stream.

38. The method of claim 32, wherein any mismatch between said first and second points is less than about 3 seconds of viewing time.

39. The method of claim 32, wherein said starting point in the second media stream corresponds to the beginning of a shot or a video scene.

40. The method of claim 32, wherein said starting point in the second media stream corresponds to the beginning of a sentence.

41. The method of claim 27, wherein said point in the second media stream is selected from one of a plurality of points in the second media stream corresponding to the first media stream.

42. A computer program product for carrying out the method of claim 1.

43. A computer program product for carrying out the method of claim 2.

44. A computer program product for carrying out the method of claim 9.

27. A method of providing media streams to a browser user, comprising:

providing a first media stream;

receiving a request from the user to access a second media stream different from the first media stream, the request being generated at a point in the first media stream; and

providing, as a result of said request, the second media stream from a point corresponding to said point in the first media stream.
