Multimedia Montage

• We need more than metadata about content

• When creating new combinations of images and video we need continuity, e.g.

– lighting conditions – background sound

– gaze direction of speaker

• left, centre, right

– framing continuity

• close-up, medium shot, long shot

– camera movement

• none, pan left/right, shaking, tilt up/down, zoom in/out

Multimedia (Metadata) on the Semantic Web

To make the annotated media part of the Web, we need

• XML to describe the presentation

• URIs to point to the media

and

to the annotations

• RDF to attach the metadata

• ontologies to explain what the metadata means

– which may use MPEG-7 descriptions
