Integrated data and real-time metadata capture system and method
First Claim
1. An integrated data and real-time metadata capture system, comprising:
- a digital capture device producing a digital representation of one or more forms of media content;
a feature extraction engine in direct digital data communication with the digital capture device, the feature extraction engine having a plurality of feature extractors to automatically extract metadata in real-time from the digital content simultaneously with the capture of the content, wherein the plurality of feature extractors extract a plurality of metadata types; and
a storage device capable of storing the media content and the metadata, wherein selected portions of the metadata are associated with selected portions of the media content.

Abstract
One aspect of the invention is directed to a system and method for a digital capture system, such as a digital encoder, having an embedded real-time content-based analysis function in the capture device to extract metadata from the digital signals. In one embodiment, metadata (descriptive information about the digital content) is formatted and stored separately from the content. In another embodiment, the metadata may be formatted and combined with the digital content in a container format such as MPEG-7, QuickTime, or FlashPix. Digital encoding mechanisms, both pure hardware and hardware/software combinations, convert an analog video signal into a digitally encoded video bitstream. The system extracts metadata in real-time during the encoding process.

17. An integrated data and real-time metadata capture method, comprising:
-
receiving analog signals;
converting the analog signals to a digital representation of one or more forms of media content;
encoding the digital media content;
automatically extracting a plurality of metadata types in real-time from the digital media content simultaneously with the encoding of the digital media content, wherein the digital media content is directly communicated for the automatically extracting; and
storing the encoded digital media content and the metadata, wherein selected portions of the metadata are associated with selected portions of the encoded digital media content. - View Dependent Claims (19)
