A content-based browsing system for a HDD and/or recordable-DVD personal video recorder

The personal video recorder such as recordable-DVD recorder and/or hard disk recorder has become popular as a large volume storage device for video/audio content and a browsing function that would quickly provide a desired scene to the user is required as an essential part of such a large capacity system. We propose an intra-program content browsing system using not only a combination of motion based video summarization and topic-related metadata in the incoming video stream but also an audio-assisted video browsing feature that enables completely automatic topic-based browsing.
