Abstract
A method and apparatus is disclosed for converting audio-video data from a full motion video format to a slide show presentation with synchronised sound. The full motion video is received from a source, separated into an audio stream and a video sequence, the video sequence is divided into a number of shorter video segments, key frames are extracted for each segment and a significance measure is calculated for each frame. A database is created wherein the extracted data is stored for subsequent (off-line) processing and reproduction. The system may have more than one system retrieving data from the database, selecting slide frames and subsequently displaying a slide presentation.
