Abstract

A system including a video stream and a data stream. The system synchronizes the data stream to different portions of the video stream.

Claims

1. A method of displaying a video with associated data comprising:

(a) providing a video from a first data stream that includes a plurality of segments and providing a second data stream including associated data respectively descriptive of the content of ones of said plurality of segments, wherein neither said first data stream nor said second data stream includes synchronization information that synchronizes respective ones of said plurality of segments with said associated data descriptive of its content; and

(b) displaying said video to a viewer in a manner such that while a selected one of said segments is being said presented said associated data to said selected one of said segments is simultaneously presented to said viewer.

2. The method of claim 1 wherein said video includes sporting activity.

3. The method of claim 1 further comprising synchronizing said associated data with said plurality of segments using information from a third data stream from a source different than that providing either of said first and second data streams.

4. A method of displaying a video with associated data comprising:

(a) providing a video from a first data stream that includes a plurality of segments and providing a second data stream including associated data respectively descriptive of the content of ones of said plurality of segments, wherein neither said first data stream nor said second data stream includes synchronization information that synchronizes respective ones of said plurality of segments with said associated data descriptive of its content;

(b) displaying said video to a viewer in a manner such that while a selected one of said segments is being said presented said associated data to said selected one of said segments is simultaneously presented to said viewer using information from a third data stream from a source different than that providing either of said first and second data streams; and

(c) selecting a previously viewed segment of said video for presentation to said viewer and simultaneously presenting to said viewer said associated data to said previously viewed segment.

5. The method of claim 4 wherein said video includes sporting activity.

6. The method of claim 4 further comprising synchronizing said associated data with said plurality of segments.

7. A method of displaying a video with associated data comprising:

(a) displaying a video that includes a plurality of segments wherein a plurality of said segments include associated data descriptive of the content thereof; and

(b) modifying the amount of said associated data that is presented to a viewer based upon a user'"'"'s preferences without modifying the plurality of segments displayed to said user that is associated with the data descriptive of the content thereof.

8. The method of claim 7 further comprising a selector that results in said modifying.

9. A method of displaying a video with associated data comprising:

(a) displaying a video that includes a plurality of segments wherein a plurality of said segments include associated data descriptive of the content thereof; and

(b) modifying the amount of said associated data that is presented to a viewer based upon, at least in part, the duration of said segment without modifying the plurality of segments displayed to said user that is associated with the data descriptive of the content thereof.

10. The method of claim 9 wherein a segment of a relatively shorter duration is presented relatively less said associated data.

11. A method of displaying a video with associated data comprising:

(a) displaying a video that includes a plurality of segments wherein a plurality of said segments include associated data descriptive of the content thereof; and

(b) modifying the speed at which said associated data that is presented to a viewer based upon at least one of the duration of said segment and the amount of said associated data.

12. The method of claim 11 wherein said speed is based upon said duration.

13. The method of claim 11 wherein said speed is based upon said amount.

14. A method of displaying a video with associated data comprising:

(a) displaying a video that includes a plurality of segments wherein a plurality of said segments include associated data descriptive of the content thereof; and

(b) modifying the associated data that is presented a viewer based upon a profile of the viewer without modifying the plurality of segments displayed to said user that is associated with the data descriptive of the content thereof.

15. A method of displaying a video with associated data comprising:

(a) displaying a video that includes a plurality of segments wherein a plurality of said segments include associated data descriptive of the content thereof; and

(b) modifying a number of lines of said associated data that are presented to a viewer.

16. The method of claim 15 wherein a viewer may modify said number of lines.
