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.
Claims41
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 integrated 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 encoding of the content;
- a storage device capable of storing the encoded media content and the metadata, wherein selected portions of the metadata are associated with selected portions of the encoded media content;
- and
- an output interface in data communication with the storage device and generating output data, wherein the output interface is capable of preserving a temporal relationship between a sequence of the metadata and the digital content,
- wherein the digital capture device comprises a digital video camera including an audio capture capability, and wherein the feature extraction engine generates a plurality of time-based tracks of metadata that index the audio content and the video content.
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 integrated 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 encoding of the content;
- and
- a storage device capable of storing the encoded media content and the metadata, wherein selected portions of the metadata are associated with selected portions of the encoded media content, and wherein the storage device comprises separate storages for the encoded media content and the metadata.
An integrated data and real-time metadata capture method, comprising:
- sensing analog signals;
- converting the analog signals to a digital representation of one or more forms of media content;
- compressing the digital media content;
- automatically extracting metadata in real-time from the digital media content simultaneously with the compressing of the digital media content;
- and
- storing the compressed digital media content and the metadata, wherein selected portions of the metadata are associated with selected portions of the digital media content, and wherein the storing includes storing to separate storage devices for the digital media content and the metadata.
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 frame buffer storing a frame of the digital content;
- a feature extraction engine integrated 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 stored in the frame buffer, and wherein the feature extraction engine generates a plurality of time-based tracks of metadata that index audio content and video content;
- and
- a storage device capable of storing the digital content and the metadata, wherein selected portions of the metadata are associated with selected portions of the digital content.
