Abstract
A digital capture system, such as a digital still camera or digital video recorder, has 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.
