Abstract

A system and method are provided for analyzing media content and generating related metadata as it is provided to a computer. In one embodiment, the system includes at least one analysis object for analyzing the media content as it is received and generating metadata relating to said media content.

Claims

1. A method of transferring media content to a computer comprising:

capturing the media content in the computer by storing the media content in a queue of the computer and by creating a media file relating to the stored media content;

storing the media file in a computer readable memory;

analyzing the stored media content as it is captured to generate metadata relating to said captured media content; and

storing the metadata in the media file.

2. The method of claim 1 wherein the media content is analyzed for at least one of:

an audio pattern, a video pattern, a face, a color histogram, a motion vector analysis, a date stamp, a timecode, a color set, a scene change, an object, and a person'"'"'s voice.

3. A computer readable medium having instructions thereon for executing the method of claim 1.

4. The method of claim 1 further comprising:

storing the generated metadata in a metadata queue; and

storing the metadata in the metadata queue in the media file.

5. The method of claim 1 wherein analyzing comprises executing at least one of a plurality of analysis objects and said analyzing occurs in response to capturing the media content in the computer.

6. The method of claim 1 wherein creating a media file comprises:

decoding the media content stored in the queue from a first format into media information; and

encoding the media information into a second format; and

storing the encoded media information in the media file.

7. The method of claim 1 wherein capturing comprises receiving by the computer rendered media content from a recording device, receiving by the computer streaming media content from a recording device, or receiving by the computer data representative of the media content transmitted from a computing device.

8. A system for use with media content comprising:

a computer including a processor for receiving the media content;

a queue for storing the received media content;

a computer readable medium for storing a media file corresponding to the media content stored in the queue; and

an analysis object executed by the processor for analyzing the media content stored in the queue and generating metadata related to the media content simultaneously as the media content is received and the media file is stored.

9. The system of claim 8 further comprising at least one of:

(1) a recording device providing the media content to the queue by rendering said media content, (2) a recording device providing the media content to the queue by streaming the media content, and (3) a computing device providing the media content to the queue by transmitting data representative of the media content.

10. The system of claim 8 wherein the media content is analyzed for at least one of:

an audio pattern, a video pattern, a face, a color histogram, a motion vector analysis, a date stamp, a timecode, a color set, a scene change, an object, and a person'"'"'s voice.

11. The system of claim 8 further comprising:

a transcoder executed by the processor for converting the media content in the queue from a first format to a second format;

a metadata queue for storing the metadata generated by the analysis object; and

wherein the processor transfers the metadata stored in the metadata queue to the media file.

12. The system of claim 11 a preview object executed by the processor for displaying the media content to a user simultaneously as the analysis object analyzes the media content.

13. The system of claim 11 wherein the analysis object analyzes the media content in response to the media content being converted by the transcoder.

14. A method of creating a media file from media content comprising:

capturing the media content in the computer by storing the media content in a queue of the computer and by creating a media file relating to the stored media content;

analyzing the stored media content to generate metadata relating to said media content, wherein capturing the media content and said analyzing occur simultaneously;

storing the generated metadata in a metadata queue; and

transferring the media content in the media content queue and the metadata in the metadata queue into a media file.

15. A computer readable medium having instructions thereon for executing the method of claim 14.

16. The method of claim 14 further comprising:

providing the media content to the queue by at least one of (1) a recording device providing the media content to the queue by rendering said media content, (2) a recoding device providing the media content to the queue by streaming the media content, and (3) a computing device providing the media content to the queue by transmitting data representative of the media content; and

transcoding the media content in the queue from a first format to a second format.

17. The method of claim 14 wherein the media content is analyzed for at least one of:

an audio pattern, a video pattern, a face, a color histogram, a motion vector analysis, a date stamp, a timecode, a color set, a scene change, an object, and a person'"'"'s voice.

18. The method of claim 14 further comprising generating a table of contents based on the metadata.

19. The method of claim 18 wherein the media file has the following data structure:

the table of contents followed by the media content followed by the metadata.

20. The method of claim 14 wherein said analyzing comprises executing at least one of a plurality of analysis objects.
