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 analyzing video comprising:

(a) identifying a plurality of events of said video, wherein at least one of said events contains a sports activity;

(b) identifying a region of at least one frame of said video containing scoring related information;

(c) identifying at least one value of said scoring related information based upon character recognition; and

(d) synchronizing said at least one value with at least one of said events in a manner free from manual association of said at least one value with at least one of said events.

2. The method of claim 1 further comprising:

(a) identifying a region of at least another one frame of said video containing additional scoring related information;

(b) identifying at least one value of said additional scoring related information based upon character recognition;

(c) associating said at least one value of said additional scoring related information with at least another one of said events; and

(d) modifying at least a portion of said scoring related information based upon said scoring related information.

3. The method of claim 2 further comprising:

(a) identifying a region of at least another one frame of said video containing additional scoring related information;

(b) identifying at least one value of said additional scoring related information based upon character recognition; and

(c) associating said at least one value of said additional scoring related information with said at least one of said events.

4. The method of claim 2 further comprising low pass filtering said scoring related information and said additional scoring related information.

5. The method of claim 2 further comprising analyzing said scoring related information and said additional scoring related information to determine appropriate scoring related information.

6. The method of claim 2 further comprising modifying at least one of said scoring related information and said additional scoring related information based upon the type of content of said video.
